GI4NKB Awarded First Place for Northern Ireland in the CQ WW CW 2007 Contest using a FLEX-5000

Frank, GI4NKB was recently presented with a pleasant surprise when he found out that he had won first place the CQ World Wide CW 2007 contest for Northern Ireland in addition to setting a new country record.  Frank contributes his unexpected success to his FLEX-5000 and PowerSDR for providing that edge needed to put him in first place.  Frank was quoted as saying...

"My score, [in the CQWW CW 2007 contest] while not exactly earth shattering was achieved with wire antennas and my amazing FLEX-5000. You can imagine my surprise when a certificate from CQ was delivered a few minutes ago emblazoned with these words:


To say I'm chuffed would be an understatement!  I credit my success to the FLEX-5000's superior receiver and feature set; there is nothing else that comes close to it. NOTHING!  Long live FlexRadio Systems and software defined radios!

Congratulations on a well earned accomplishment.

Bob McGwier Wins the 2007 John Chambers Memorial Award for Technical Achievement

At the Central States VHF Society (CSVHFS) meeting held recently in San Antonio, Bob McGwier , (N4HY) the co-author of DttSP and a major contributor to FlexRadio PowerSDR, was presented the 2007 John Chambers Memorial Award for Technical Achievement, recognizing his many SDR and AMSAT activities. Bob joins prestigious group of previous winners which includes FlexRadio CEO GeraldYoungblood (K5SDR) along with John Fox (WØLER), Ron Dunbar (WØPN) JanKing (W3GEY) and Tom Clark (K3IO).

Bob, ever modest in his reactions to such awards was quoted as saying:
"Ihave had great partners in all of my work. I am grateful for all ofthe ideas, support, trust, complaints, advice etc. that have flown freely from the SDR, Flex groups, TAPR, ARRL, and of course, AMSAT. It has been amazing fun to try out new ideas here and to work with Frank[Brickle], Eric [Wachsmann], and many others on our joint endeavors. I do not covet awards and I certainly don't seek them but the John Chambers award is one I am extremely proud to have as all of my engineering mentors in amateur radio have received it including, but not limited to Tom Clark and Jan King. This was a complete shock.”
Bob credited Tom Clark with talking him into doing the DSP project with TAPR and AMSAT while still in college. That advice and encouragement made a tremendous impact on Bob’s life, defining its trajectory almost totally. His close relationship with Tom has gone on for over 25years.
“Tom often does not seem to see that of all his contributions, the most important of all byfar is the impact he has had on others through his friendship,mentoring, and leadership. In my mind, it is the one of the most accomplished lives in amateur radio and beyond if you completely subtract all of his technical work.” said Bob.
Congratulations on winning the award and thank you very much for your continuing work to advance the state of the art of radio communications. We all owe Bob our deepest thanks and appreciation, for if it was not for his contributions, there would probably not be FlexRadio PowerSDR and the fine transceivers it runs.

KMØT Record Breaking Rainscatter QSOs with the SDR-1000 EN13vc to EN73cb on 5.7 GHz and 10 GHz – 1st Place for US5.7 GHz and 2nd Placefor US 10 GHz Rainscatter Distance

On June 22, 2007, Mike, KMØT in grid EN13vc worked Erv, K8EB in grid EN73cb on 10,368.103 MHz CW – a total distance of 526 miles (847 km). This distance was enough for 2nd place for the longest distances on 10 GHz rainscatter in the US. After this record breaking QSO, Mike then was able to work Erv on 5.7 GHz after having to make an emergency rotor repair. This 5.7 GHz QSO broke the US distance record for a 5.7 GHz rainscatter QSO.

Mike uses the SDR-1000 with FlexRadio PowerSDR as a 28 MHz IF to drive multiple microwave transverters along with the Universal Controller Board (UCB) for IF switching.

Mike has been quoted saying:
"I had always dreamed about a radio and interface like this, but I never thought it would ever happen. I sometimes catch myself staring at the screen showing the microwave band frequencies thinking "Man this is awesome!" Seems like every time I turn around, there is something new coming down the pipe to make the whole setup better!"

Mike has been active on the VHF and microwave bands for a number ofyears now utilizing the Flex-Radio SDR-1000. He has won 1st place nationally in the ARRL UHF contest the last 3 years. In 2005 he used the SDR-1000 for the 902 MHz thru 24 GHz bands. In 2006 he utilized two SDR-1000s to feed all the bands used in the contest. He also holds one end of the US distance records for other microwave rainscatter contacts utilizing the SDR-1000, namely 902 MHz, 2.3, 3.4 and 24 GHz.

It is worth the time to make a visit Mike's web site where he describes in detail how he has modified his SDR-1000 to make his fabulous award winning VHF+ station.

Congratulations are in order for Mike and the SDR-1000. Great job, Mike!

NJ1H using a SDR-1000™ & R5 Vertical Takes First Place Low Power in the 2006 CQ SSB World Wide WPX Contest

Bill, NJ1H using a SDR-1000™ and a R5 vertical has taken first place in the low-power CQ SSB World Wide WPX Contest for the Single Operator Assisted category - All Band division for 1ST Area.

Bill's final score was 186,714 points which was accomplished by logging 323 QSOs and 253 prefixes. On air time was about 17 hours. Of the 329 submitted QSOs, only 6 were bad or "busted" QSOs.

The award was officially announced on page 111 of January 2007 edition of CQ Magazine
"This [award] was a surprise to me as I have a modest station. My effort was search and pounce with all contacts on 20M through 10M using the R5 vertical except for 2 contacts on 40M with a random wire in the attic. The [SDR-1000's] Panadapter is great for search and pounce. I almost always click tune with the mouse on frequency enough to make the QSO. The SDR-1000™ was definitely a contributing factor [in winning first place]." Bill commented.

Bill's "contest station" consists of N1MM contest software in conjunction with the SDR-1000™ operating with M-Audio Delta-44, Santa Cruz & MB sound circuits running all software on a 2.53 MHz P4 & 1G byte of memory. N1MM to rig communication was accomplished using a virtual port. A voice keyer were also used. The Santa Cruz soundcard provided microphone pre-amp and voice keyer output/mixing function. MB sound circuit provides additional computer sound mixing functions.

FlexRadio Systems congratulates Bill on a job well done!

 First SDR-1000™ to SDR-1000™ EME "Moonbounce" QSO

I'm happy to report that Dave, W5UN , and I completed what we believe is the first EME contact using an SDR-1000™ on each end of the contact on August 19, 2006.

I was able to visit Dave, W5UN on Saturday, August 12th, 2006 with the purpose of getting his SDR-1000™ (original owner W3EME ) upgraded and operational. Dave upgraded his sound card to a M-Audio Delta 44, and loaded up the virtual serial driver, Vcom , from Phil N8VB . He had all this installed, and running, prior to my arrival at 10 PM that night.

We "tuned" the installation, and listened to signals off the moon until 3 AM. Things seemed to be working as desired. His old setup was using a Sound Blaster Audigy 2 (if memory serves me). Upon installing the Delta 44, his observation was

"This radio went from something with potential (read that as poor ) to a real high performance radio!" .

Fant, AA5F , and I left his QTH around 11 AM in the morning with Dave on a mission to incorporate the SDR-1000™ into the primary operating position of his station. I continued my trip from east Texas to an unplanned week long work assignment in Raleigh, NC arriving back at my home QTH a week later.

After finally arrived home at 1900Z on Saturday, August 19th W5UN calls and says he's ready to run at 2200Z. We start our EME QSO using a digital mode called JT65B from the application - WSJT . Twenty five (25) minutes later I finally heard and saw Dave's signal on the radio. I was a little worried because they was a ripping aurora going on with some signals reaching 20 over S9 on my receiver whenever I aimed north. We completed this historic QSO by 2230Z.

It was a great day in my shack!

Both SDR-1000™ computer configurations used one (1) CPU
(everything running on one PC)

  • Preamp in the shack

  First DXedition using the SDR-1000™ in Belize as V31SR

Well the Belize DXpedition is officially on it's way. Tuesday everyone arrived and our host Bob Fox was very welcoming and helpful, getting us settled in the resort. The afternoon and early evening was spent getting V31SR computer and radio set up as well as the DSL modem, wireless router and other gear. It is a minor miracle that the AA4SW gear made it. A rugged looking file case containing the entire bare bones station could not be carried on as anticipated, and arrived in Belize with the bottom of the case falling off. Some packing tape at the airport temporarily held the bottom on and nothing was lost, The ATX case was dented. Also the rugged transit case looked 'sucked in' on the sides putting in doubt whether the LCD monitor made it. Everything did, but it should be a challenge to get it all re-packaged for the trip home . The flight down from Belize City was rather a hair raiser. About 20 folks packed into the plane which seemed a little overloaded. Carson, the last person on sat in the co-pilots seat. The 'airports' are not much more than poorly paved strips only a little wider than a 1.5 lane road!


V31LL jumped right on Bob's Kenwood and had a pile up going for about 1/2 hour before we kicked him off the air so we could set up. We were all thrilled to listen to him make many contacts, with anticipation of what is to come. Terry V31TG made a couple of Q's on the SDR-1000™ before we all went to 'happy hour' and ate.  The 8' x 10' foot shack is not really conducive to setting up 2 - stations and an Internet communications post, but will do the best we can.  Carson and I collapsed after 21 hours of combined travel and set up.

We did manage about 3600 Q’s in the 48 hour period. Not shabby, but not top score, which I now know that this radio is fully capable of doing. Murphy took advantage of all our mistakes. The biggest one perhaps was not being able to run more power in a contest, where ‘more power’ does not make any difference. The 3600 q’s were managed at 60 to 100 watts on 2 radios. Both the laptop station and desktop performed magnificently as did the operators! It is a bit frustrating to be able to hear everything and even ‘select’ it out, and not have the ‘punch’ to work it over the American stations.

Several highlights of the trip was working K5SDR (Gerald) one time and working multi – 2 exclusively with SDR– 1000™ radios and faring pretty well – AND realizing that with a few tweaks this WILL be the consummate contest rig for any contest!
