Javornik 14/144MHz VHF transverter H.M. by I1KFH – still wait on air test .. [update 02/2018]

update 02/2018:

I want to add some detailed pictures about Javornik transverter 14/144MHz finally boxed and tested in order to highlight the great work done by Sergio I1KFH. Some years ago we focused on this project, but it wasn’t available already build nor also in kit, then we bought only the original board with other few particulars components from the producer (S53RM) while we purchased the remaining parts from the major supplier in Europe. Some components were even found during my job trip in UK, too.

Finally, a lot of work by Sergio with his skilled level then my boxing . Here the result:

Javornik 14/144MHz VHF transverter H.M. by I1KFH – still wait on air test

 

JAVORNIK-  short description: 144/14 is a very high performance transverter for 144 MHz optimized for use with the FT-1000MP as a 14 MHz base station , and it has two (synchronous) receive converters with enough gain to overcome the 18 dB of FT-1000MP’s noise figure (in IPO ON state).

Summers,14-17: IS0/IZ1ESM/M activities.

Last years in July and August I had the opportunity to enjoy  Sardinia island more than once (in particular the south-east zone). I’ve personally never performed in portable before, so I decided to discover mobile activities thanks to my son’s Suzuki G.V. using this setup: RTX YAESU FT100, HF mobile HUSTLER  antenna with 10, 15 and 20 meters coils on a triple magnet base (also if I don’t transmit while running)  or in alternative  I used also a six meters fishing rod with a 4:1 balun and AT120 tuner by Kenwood. Working in these conditions has been really amazing and I gained  also some nice DX with my simple setup and I must highlight that Hustler antenna has been really performing and for my experience better than the 6mt  fishing rod antenna.

Anyway, the beauty of this land has been the most marvellous aspect of this experience.

Dec. 2017: NIR-12 dual dsp by JPS

Many years ago I tested the external DSP signal processing, but I  wasn’t really certain about its real functionality, because I didn’t appreciate any important improvements. Then the first RTX with internal DSP was launched into the market and it entirely replaced the audio DSP. But in the last time due my choice to use on HF my preferred rtx (the YAESU FT1000, an old style radio) and thanks to the visit to the I1POR’s shack (FT1000 and NIR12 user too), the functioning of NIR12 surprised me a lot. I’ve surely evaluated the recent BHI DSP module or some alternatives, but I’ve decided to look for the same setup heard.

IMG_3411.JPG

After few months I visited a Hungarian ham web market, and finally found the NIR12. Some tests confirm its good functionality, really helping in many situations. I will make some videos showing its high level.

Feb.2017: UltraBeam !

with the first nice weather, the good TH5 Hy Gain it’s been replaced by a powerful and actual  UltraBeam 3 elements 6-20 meters yagi … first test was on full functionality, elements adjustement and check of CAT command through PC to rtx … also rotator it’s been improved and now is an HAM IV always by Hy Gain.

Sept.2016: VHF IARU reg.1 contest

After long time I’d Enjoy again this VHF appointment and worked 6 hours category in Saturday using the VHF home setup like Elecraft K3 and transverter TR144- H by Kuhne with 500 W on a single 17 el. M2-5WL … without adding  other antenna systems. The activity was interesting and after the usual short QRB contacts with nearest zone answering to my call, finally I’ve looked to improve the final QRB average (and also my personal pleasure) with some DX QSO. Not new calls or locators: ODX with OM6A (as usual) and its 902 Km and for stats 16 QSO over 700Km and among others the QSO in JO31 with DL0GM and jn JN94 with YT4B …. not so usuals squares  from home location … closed with declared of nr. 109 QSO and over 45K points with 416 QRB average really in-line with past results with similar working/location conditions. On Italian side I would like to highlight the usual top ops/teams activities as IQ4AX drived by IK4WKU Marco, the new call IQ5NN for Nerone Team with I5PVA Paolo and IK5ZWU Andrej, the IK1TBE Team drived by I1AXE then IO2V with IK2CFR Marco and his team, this time (as already done on 2001/2002) working over 3000 mt a.s.l. from “Marmolada” for sure the biggest Italian windows on EU countries and at the end with the great operation done by IK3UNA Mirko that worked DQ8T contest club form DG8NCO shack in JO50 that gained a top score (over 600 QSO more than 210K pts) in Italy normally reached  only by multioperators and portable teams: really a great job !

April 2016: HF tuner Palstar AT2K

Just replaced the HF tuner MFJ 989C, in the shack since an old trip to Freidericheshafen (2001),  with the powerful Palstar AT2K .. just looking the external dimensions and confirmed by the same range of the capacitors (4,5Kv) drived by 6:1 ratio Vernier dials more than the inductor variable ceramic core roller with a silver plated roller wheel and an high precision mechanical counter, this tuner gives a good idea about its performance … it is capable of manage 2KW PEP SSB from 1,8 to 54MHz .

March 2016: worked on CQ WPX SSB contest

The first HF contest experience  started with the category choice, dropped on Single Op, 15mt, Low Power, Assisted, TB, then some quick tests with the powerful QARTtest contest software by IK3QAR , and rig “setup” like the YAESU FT2000 (100W) more the voice keyer MFJ434B with the Heil headset and  footswitch …  The band was really crowded with many prefixes on-air, as the intent of this contest due they are multipliers, and only the power limitation of my category has added a bit difficulty to complete some QSO (especially in answering while not on my CQ calls), caused by the power difference because the OMs contacted often were HP, furthermore adding for sure the worsening of reception levels due local high QRM everywhere … remarkable on Saturday the first CQ with a nice East land feedback particularly from JA, and Sunday late afternoon when the band normally went closed while this time had a new increment peak with a lot of activity until 22Z that seemed with no end …

I’ve really joined this experience and I’ll surely reapeat and improve it because this time I’ve lost too much time with personal problems both days  … In the end  I’ve reached  385 QSOs for a declared over 290K pts. but this time the points weren’t the real objective ….

UPDATE on 06, April 2016 :

as  in the picture from CQ WPX web site the RAW score where I’m temporary in positions :      # 1 ITALY ,  #3 EUROPE ,  #13 WORLD

March 2015: the milestone in the shack ..

I’ve been looking for a YAESU FT1000 transceiver since long time and now finally is in the shack … the charm of this milestone is really incredible.

Introduced at the end of ’80 with the high-end competitors  like Icom IC781  and Kenwood TS 950 , this rtx came out as “… the highest third-order input intercept of any commercial radio ever tested in the ARRL Lab … “ more ” .. .ultimate contesting and Dxing machine available today  …  YAESU has every reason to be proud of this achievement …” on Product Review in QST March 1991. In the short test performed until now, I’ve been really impressed about the result by the comparision with the most modern transceiver on the desk …

Sept. 2014: HF antenna system ready !

The TH-5MK2 by “Hy-gain” has finally found it’s right location over the 12 mt. “Angelucci” tower with trolley, driven with cellflex RFS LCF14-50 and inflex RT 50/20 cables while the rotator is a CD45 always “CDE Hy-Gain”. I know that this antenna isn’t “actual” (i.e. without WARC bands or dynamical) but is for sure enough for my actual HF target.

May 2014: ARI VHF Trophy Award 2013

Last May,18th, I attended the ARI VUSHF Meeting in Marina di Pietrasanta where I received this award for the 1st place in the 2013 ARI VHF Trophy cat.6h  from Alex IK3KKW ARI VUSHF Manager. It was a very nice end for an intense 2013 season lived with Roberto I1BPU, starting with some “contest” setup improvements to my fixed station, until the portable operation of July and November as detailed in the previous posts and also with the big result in September again in fixed station but with Davide IZ2UPJ. The main competitor Alex IW3INQ and his team (IK3TPP, IV3KKW and others ) has been overtaken with a great and powerful effort, always with setup changes more than improvements and relative better results.

VHF Int.”Cinisello” May 2014: looking for DX …

In this appointment  I’ve tried to hunt any good DX available on the band, leaving any relation about the total score, but only looking for the system capability in order to evaluate one time more any possible improvement. For this reason the “home setup” with Elecraft K3 & Kuhne TR144 and the M2 2M5WL 17 el. it’s been used without any addition due his capability on that kind of activity. The tropo condition was nice since the contest startup on  saturday confirmed with  the good QSO with OM3W in JN99CH and 874Km going to the ODX with HA6W and his KN08 with 974Km worked in the evening. On Sunday, the tropo condition wasn’t so good, confirmed by some unlucky test on sked through KST chat, however some interesting QSO has be done like with  HG7B in JN97 and 865Km , 9A0V in JN95 and 850Km or OM5AW in JN88 and 827Km .

At the end the total QRB average about this test was 653 Km. Here a graphic detail:

Upgrading Bird 43 with PeP card

Some time ago, I had the opportunity to get this original Bird kit upgrade (mod.4300-400) that convert any Model 43 to accurately read Peak as well as CW power. The main card of this kit need to be fixed directly on the instrument, while at the place of DX socket for extra element, must to be installed a command plate with a switch and a LED to indicate the meter is switched to Peak mode. Here few shot to show the steps of this easy and  “no wiring” installation …..

VHF Int. Contest “Lario” March 2014

This appointment was performed with a temporary installation of a 10el. BJ9BV design added to the main 17el. 2M5WL drived by the new couple Elecraft K3 more Kuhne TR144 and 500W. The activity was related to winter conditions with a low average and not enough interesting DX but anyway on the top 20 QSO there are nr. 4 QSO over 800 Km and 16 QSO on 600 / 700 Km range while the DX was with HA5KDQ in JN97LN and his 853 Km. The first experience with the improved setup it’s been very interesting showing the high capability of the system.

Last 2013 setup update: Elecraft K3 !

What better way to close  the winning 2013 VHF Activity with a new setup upgrade like a new rtx K3 by Elecraft ? I don’t think more other : so here in the shack my last improvement, instead of my glorious Yaesu FT1000 MP ( still on side) to drive the TR144H+40  transvert by Kuhne El. (DB6NT).
The K3 was arrived on 24,Dec in “VHF model”  like K3/10 with the option KXV3A transverter interface, in kit version. In the firsts 5, 6 hours available, I’ve assembled it without any problems: the instructions are very detailed and all the parts supplied have found their location. At the end, after hold my breath at the first power up, I’ve started to experience the basically functions in order to discover and learn how to take advantage by it’s high performance. After the mainly setup and some test  in HF bands, the K3 is already connected to the Kuhne …

The first approach was very interesting  and a few time after the use on-air, is quicly and easy understand the fame and the success of this great and widely reviewed tranceiver. I have also connected the PMSDR on IF out and with POWER SDR/IF-stage software now I am testing the PC based Panadaper tool for the next ES and  Tropo activity season.

2013 ARI Trophy last step: [MMC] Marconi Memorial VHF

I’ve reached this last appointment with the 2nd position in the 2013 ARI VHF Trophy “6 hour category” and about 5k pts backward so, in order to try to gain the 1st position, I haven’t any other choice to make a portable operation: obviously the season bring many doubts about weather conditions especially on high mountain locations ! Moreover Roberto I1BPU cooperation was not sure until few hours before the deadline … but at the end he confirmed and we started with this hard attempt.
Saturday, after about 3 hours travelling arrived in place over 1500 mt a.s.l. but unfortunately inside fast clouds with low visual, strong (and cold) wind and high humidity level. In this situation we have raised up the two systems, a 2 x 7 el. and a 4 x 5 el. (all vertically stacked) on DK7ZB design h.b. by Roberto …

 

A quick test with the antenna analyzer highlighted a problem on the 4 x 5 system (also if all checked before) that forced us to tear down and then up again all the system to clear it, and in that bad weather conditions isn’t been so simple . The dark of the evening was arrived early but we finish antenna mounting not long after  … On Sunday morning we were really pleased to see the two system still upright, due the high wind bursts of the night, and still there, so we started to connect all equipments inside the van.. then the first QSO in log … the local activity appeared less than usual related to the other contest due to “only CW”  reason, but on the other side the higher QRB average is evident and many good QSO with remarkable QRB are easily in log simply coming back to our call on our QRG. This is confirmed by the 30% of QSO that have QRB over 700Km (detailed on nr.3>900Km, nr.17>800Km, nr.19>700Km), by the 7 QSO in KN field (from 04 to 08) and also by the ODX with YU7ACO in KN05QC and his 959Km. Obviously the “KST” chat has brought some support to our hunting but hasn’t defined a heavy result difference. All the activity was done while the weather conditions were changing with the first sun was breaking the overcast …. At 14 UTC all switched off, and we go ahead to dismount all, finishing more than 2 hours later and more 3 hour’s travel for archive this hard but nice and successful experience with Roberto, closing with these numbers:

158 QSO, QRB average 481Km, DX YU7ACO in KN05QC QRB 959Km, declared 76089 points

and, as said, inside these ; nr. 51 differents WWL, nr.13 DXCC calls,  42% points vs. dist. over 700Km,  nr. 3 QSO over 900Km QRB, nr.17 over 800Km QRB , nr.19 over 700Km and nr. 18 calls 9A, nr. 11 calls HA, 17 calls OK, nr.8 calls OM ending with nr.21 calls S5 , nr. 5 calls YU and nr. 1 call ON … really fun !

October 2013: new improvement with a PHOENIX 1000 LDMOS amp. by ITALAB

Recently I’ve decided to upgrade the glorious and very reliable amplifier AM6155 by ITT Aerospace  with his 8930 Eimac tube and over 500W (in my shack since year 2000 and sold few days ago) with a new generation technology amp offered by the last equipments on the market.  After some phone calls I’ve met Nico, ITALAB head, in his lab nearby Milan to purchase his last product:

PHOENIX 1000A 144MHz, 8W @ 1 KW,  Tho-Tzu CX600N / CX140D relais,

EATON-TDK APR48 power supply and MRFE 6VP61K25H Freescale LD MOS

Really a compact and powerful equipment. Below some pictures about Nico while is testing my amplifier on his power desk lab (with Franco,I2FHW on the background), checking the full power and all protections (max.input, high SWR … etc.) and finally the new amplifier test in my shack …..

IARU VHF 2013: over 80K points in 6 hours !

I never reach a great result like this from my home station on side of QSO number and total score … really a great result and probably is the Italian record in 6 hour category from fixed station and, more important, also this time in the current ARI trophy season, the score is better then the previous (beyond the portable op.). 
In the shack I’ve had the cooperation of my dear friend IZ2UPJ Davide (ex IW1DMC) that give me his really appreciated availability while I1BPU Roberto was engaged as a member of the IK3UNA, Mirko’s Team , moreover the home setup it’s been improved with a temporary 2×7 elements DK7ZB h.m. provided by IZ1GDZ Cesare (thanks) in addition to the main 17 elements by M2 inc. (2M5WL) drived by the couple FT1000MP with the Kuhne TR144H+40 and the power (500W) splitted in the two aerial systems.

The activity it’s been in high level as IARU VHF reg.1 main contest, also if lower in the nearby area, with nice QSO in 9A (nr.21), OK/OM (nr.20), S5 (nr. 22) with a total of nr. 2 QSO over 900Km and nr. 19 QSO over 700Km. and among that YT4B from JN94SD and HG7B from JN97LW really loud, until the best DX with OM6W in JN99LJ and its QRB of 927 Km. QSO Map

 208 QSO, DX OM6W in JN99LJ, QRB 927, average 386Km, declared of 80423 points 

Now 2 month in stand-by, waiting the last 2013 ARI Trophy appointment : Memorial Marconi VHF CW on next Nov.02/03 fighting for the first position

9A Activity Contest 2013

It’s long time that I’m active looking for DX each third sunday morning due the “VHF Activity Contest” present in the East Lands, but I’ve never sent the logs. This year, also thanks to 9A2HM mail invitation received in February and in order to highlight the VHF activity of my zone gaining more attention in the International contest (i.e. antenna turning), I’ve decided to send the log in “9A VHF portal” of my activity.

After the first log sent about the 5° period (May) with a score of 21 QSO and 13722 pts, average 653Km/QSO and the  pos. of this period, while the 6°  tournament (June) has got a better result with 35 QSO for 24264 pts. and an average og 693Km/QSO, that reach the  position in this classement. Need to be highlighted the good QRB average of these appointments that permit to have a low total QSO numbers but with remarkable total score: the nearby competitors often are over 100 QSO instead my few but long contacts. I hope to have time availability to attend the next appointments. More info and full classement on 9A VHF portal.

2013 ARI Trophy: July step, IZ1ESM/1 from JN44OR !

In order to improve again the score and after the previous test from my home locator and thinking to have reach the physical limit of my location, this time me and Roberto, I1BPU have decided to … pass up to the portable operation.
Saturday 06 July in the afternoon we moved in JN44OR at 1550 mt ASL, a wonderful location that only with the panorama let thinking about wonderful performance….but we have encountered the first problem due the BPU “Contest VAN” didn’t gained the top of the field with the wheels sleeping on the humid grass, and only pulling it with the 4×4 we arrived in the right place. Started with the two  antenna systems mounting, the first with turnable 2 v.stacked 7 elements and then the second with 4 v.stacked 5 elements fix to NNW, all on DK7ZB design H.M. by Roberto and after the place in position of the Power Generators.
In the evening we started to connect all the radio setup inside the Van and performed the first receiving test in order to verify all the systems, but we have encountered the second problem: a remarkable low signals on the 4×5 group confirmed by high SWR . At 0:00 AM we decided to take down the system (dismounting step by step the stack) finding the problem. Found it, we fit up again the system, finishing at 1:00 AM.
Sunday 07 July  after the last check, we have started our 6 hours: the first was closed with 61 QSO (!) and after the second the QSO numbers was 105 (!). It was  the first time the I experienced a mini pile-up on my calls on VHF … really extraordinary. Also incredible is the “normal” replay at our calls of YU station from KN field. Very high the feedback received from  9A, OK and YU lands stations, many with strong signals that has  permitted  really fast QSO.

The difference of the location has definitely done the confirmation of the powerful range because  also the best setup cannot be compared with the position chances, and this one is wonderful ! The top is reached in the DX with  YO2YLN from KN15 and his 1011km …. and at the end we have nr. 19 QSO over 800km !
between the other, the best numbers are nr. 27  9A,  nr.25  DL, nr. 18  F, nr. 11 OK , nr. 6 HA and nr.9  YU and with nr. 10  JO more nr. 7 KN field locators, permitting this great final result :

229 QSO, DX YO2YLN, QRB 1011, average 393Km, declared of 90041 points

For our knowledge, is the highest score never reached in the 6 hours category … really a great success !! and this probably will get the temporary first position in the ARI Trophy, but for sure it’s been a great interesting HAM experience, and also this time thanks to Roberto and his incredible enthusiasm.

E-Sporadic 144 MHz summary on 2013

June, 18

ESmap18giu2013

Third chanches of this 2013 ES season with a new big opening in the later afternoon where the east zone has been present for more than 2 hours, ending with a fast QSB of the last QSO. More evident than the previous opening, the “reception” zone with some close locator was still working while not here and viceversa but not enough to avoid some little pile-up. To leave the band clear, also this time from my side I’ve used 150W. The log:

16:52 LZ1ZX KN32IO ; 16:59 LZ1ZP KN22ID ; 16:59 LZ1KG KN31CS ; 17:03 TA1D KN41LB ; 17:08 LZ1DP KN22TK ; 17:09 LZ1JH KN12PQ  ; 17:10 LZ3RX KN12TQ ; 17:15 LZ2RBB KN12QP ; 17:20 LZ1GHT KN12QP ; 17:22 UX0XFF KN45KJ ; 17:48 YO6XK KN25BS ;  17:55 YO7GM KN05EI ; 17:59 YO3FOU KN34BK ; 18:21 YU5C  KN02XX ; 18:24 ER1LW KN46KW  ; 18:29 LZ2ZY KN13OT ; 18:32 LZ2FO KN13KX

  

June, 09 ESmapEU_09giu13

Second opening worked on 2013, but this one really great since long time… I’ve started at 17:20 UTC and a lot of activity is gone until 18:50 …in the log 9 CT stn adn 8 EA stn.. this time also a remarkable high local activity due  sunday holiday. Here the log:

17:21 CT1DDW IN60BP ; 17:26 EA4AZZ IN80AR : 17:28 CT1HZE IM57NH ; 17:30 CT1HSO IN61CB ; 17:37 EA4BMF IM69TL ; 17:40 EA4LU  IM68TV ; 17:46 EC4TR  IN80ER ; 17:48 CT1ANO IN51RE ; 17:55 EA1BYA IN70WW ; 17:58 CT1ASM IN60BP ; 18:01 EA1BYC IN70DX ; 18:10 CT1APE IM59KL ; 18:18 EA4RN  IN80BC ; 18:19 EA7ITL IM66WK ; 18:21 CS7/PD0HNL IM67EF ; 18:45 CT1EWD IM58KP ; 18:50 CT2ILN IM59JK.

 

May, 30 ES30may13

Today I’had the opportunity to enjoy the first couple of ES QSO in this year …
After hearing EA1ASC but quickly dropped in the noise, the first chance at h 18:12 CT1BXT frm IM59PF ( 1556 km) and after dinner, the second openiing at h 19:53 CT1DIZ frm IM58PK (1602 km) with a strong signal (over 10dB) really coming up like a thunderbolt . Remarkable the very low number of station active on the band in both side, missing the opportunity to take advantage about this strong ES opening. More info about the 2013 ES opening season with full database on MMMONVHF site .

May 2013, back on 50MHz again …

FT100_50MHz

Since 2002 I haven’t works on six meter … my activity on  this band, was started on 1999 when the 50MHz was available also for class. 2 licensed, and  that time as IW1ESM, I’ve got the first experience with a Kenwood TS60 ( 50-54 MHz 100W ) and a simple 4el. Fracarro ( modified TV antenna for VHF channel E2 ).

Few time later I’ve upgrade the aerial in a A50-6S by Cuschcraft, installed in a little 6mt.  tower, and also the transceiver in a more flexible Yaesu FT100. Also if I’ve bought a 6 el. by Hy-Gain (mod. 66DX) I’ve never installed, and in the last day I’ve sold it. Looking on web cluster a lot of spot about six, I’ve decided to install my old 4el .again and just today I have enjoyed some nice EU QSO with a full day ES … really fun ! so, back on 50 MHz again ….

2013 VHF A.R.I. Trophy : the second step ..

May,05 2013  VHF Intern. “Cinisello  Balsamo”:

Another nice Contest with I1BPU Roberto, using one time more an upgraded and powerful system rather than before. A new 2x7el. DKZB system ,vertically stacked and fixed to SE has been added to the previous setup of the 1x17el. 2M5WL and a 4x5el. DK7ZB system also vertically stacked and fixed to E direction: these three systems have got a large coverage allowing to capture an extended area full time. Furthermore, the first test on-air of the TR144H+40 by Kuhne, has got a very good impression with an optimized FT1000MP setup: only one very close local station (with an uncertain output quality)  have created sometimes little problems to this strong couple.

Analyzing the result, also if we have obtained an higher QSO number and a good score improvement, the location don’t permit the right jump related to the system upgrade. This is easily observed looking the operating system condition of other competitors, also in other category, that with more simple system can obtain a bigger result (more QSO ad higher score). Also the useful QSO maps that we can find everywhere on Internet, highlight that the main Italian activity area is centered in the nord west and in nord center Italy zone.
Anyway a personal higher score it’s been reached, and this is really close to  the best one obtained in the past 24h contest but now worked only in 6 hours:

165 QSO: DX OL9W in JN99CL with 884km, 6 qso OVER 800km,  declared of 62220 points      Report   QSO map

Apr.2013: new transverter TR144 H+40 by KUHNE electronic GmbH of DB6NT

Great improvement of the 144Mhz setup with this new arrival !  After the use of the LT2S since 1999 I’ve decided to get the most quoted transverter actually available on the market: the TR144 H +40 by Kuhne electronic.  It’s been supplied with the option nr.05 related to 14MHz  IF frequency, in oder to take advantage about the best receiver linearity of many rigs, including the  YAESU FT1000 MP, on that frequency. Now I hope to test it in contest asap.

March, 2013: “Contest Sezioni VHF” worked with call IQ1AO/1

After long time and some nice results (2° on 2001 and 2002 in 2nd class call category with my old call IW1ESM) , this year I’ve  decided to participate to the contest related to the ARI sections but, enjoying the spirit of the contest, I’ve chosen to use the ham-call of section ARI of Casale Monferrato nr.1503 were I’m proud signed:  IQ1AO/1 . Basically on this contest the multiplier are the ARI section number and for this reason hunting the new one is very fun. Started with a lot of I2 zone, a great crowded field, followed by I3 and many I5, two I0 until IC8FAX and IC8AJU from JN70 and F1EIT in JN03 closing with nr. 14 QSO in 9A land (no one Slovenian Station heard: all on holidays ?) but unfortunately I’ve not taken any improvement by the presence on air of the Chzech Activity contest active in the morning. Nice it’s been to receive the support of other ARI Casale  members,  like Giuseppe I1OJE, Mario I1RJP, Sergio I1KFH, Giampiero IW1CKM and Giovanni IW1ANL. Thanks to all!   Here the result:

108 QSO and 49 section;  DX 9A4V in JN75KI with 817km,  declared of 1248030 points

Update on Oct.2013: IQ1AO/1 3rd place in the final classement, and 3rd place as “North Italy ARI Section”

2013 VHF A.R.I. Trophy : SEASON STARTED !

March,03 2013: VHF Int. “Lario”:

Great news! In this appointement with Roberto, I1BPU the setup it’s been improved with a temporary installation of a 4x5el. (design DK7ZB,  HM by I1BPU) vertically stacked and fixed to 70° in addition to the main 17el. by M2 mod. 2M5WL. The power it’s been divided in the two systems, full active on TX  with the choice of the RX group. Also the operations it’s been centered on the “CQ calling” instead of  finding QSO on the band going only on reply. These changes, have permitted to reach a remarcable result about QSO number and final score (NB always related to 6hour operation and previous editions):

145 QSO:  DX OM3W in JN99CH with 875km, 6 qso OVER 800km,  declared of 51897 points  Map   Rep

This is a very nice result, especially if compared with the winner team of  IW3INQ,  for sure an high level team but based on multioperator and portable station. Moreover the latest operating mode differences with the long (neverending) setup optimization, have permitted to overtake IZ1OKG team (also multiop. and portable station) since the middle of the season, underlined also with the first place and the good score of the last two appointement  IARU and Marconi.  Here the podium of the Trophy, and you can find whole classement in the official data.
