RTTY-SO2R audio clips

Those mp3 files, recorded during the ARRL roundup 2006, demonstrate how it is possible to boost a slow running rate, into something decent using SO2R... To enjoy them, you need to open 2 instances of MMVARI or MMTTY(or one of each!) and select stereo left-channel for one instance and stereo right-channel for the second one... (using MMVARI select mode RTTY-L and tones 2210Hz).
If you are interested, my general station setup is described here (my modest domestic station!):
http://f6irf.blogspot.com/2005/08/so2r-minimal-setup.html
And here are pictures of the high-band beams and the low band dipoles:

roundup extrait 1.mp3 Audio1: Calling on right radio (IC756pro2), searching on left radio (IC706). While the rate on 20m is relatively low, the overall rate becomes quite good. The antennas are side by side, separated by12m.- Absolutely no desensitivation/interference between the 2radios, here at 150W power level.


roundup extrait 2.mp3 Audio2: Same as above but the steppIR(on 15m) is looking at the back of OB6-3M(on 20m)... no interferences either. Note that it is possible to make 2 QSO's at the same time, while never having more than one signal on the air!


roundup extrait 3.mp3Audio 3: Same radio configuration but calling on 80m, while searching on 40. The antenna separation is only 1 m ! To hear me at LP-level, it means that VK6HD hears are much better better than mine!

F6IRF: And the QSL's ?

With over 30,000 QSO's per year, QSL'ing becomes a big problem. Sending 1QSL /QSO would be both expensive and useless (a majority of contest QSO's are done with the same stations... who furthermore are not QSL's hunters...). As it is impossible to guess who is interested by your card, the best remains to wait for the cards to come, and to try to answer them in an efficient way...





Step1: the received bureau cards are sorted by bureau.
Step2: Each received card is captured in BV7 software. Each small window corresponds to a different callsign I used in the pass. Entering the callsign, I can immediately see which band/mode for which of my call still needs to be confirmed.





Step3: when all the cards for a given bureau, have been queud, the calls are printed. The software takes care of the alphabetical order sorting. I do not use anymore labels, but rather directly print on the cards (it saves the annoying sticker gluing step!)





step4: each card printed is verified and signed


Here are the main bureau customers: from left to right K, SP, I, JA and DL... To be noted, the K stations are by far the most present in my logs... ahh if the rest of the world could also use LOTW!



Step5: Finaly the cards are packed and sent to the REF !
This represents only 4 monthes, the same volume is sent 3 times/year





Following are the statistics provided by BV7 (started to use it in 2004)
F6IRF: QSOs printed: 7855
FG/F6IRF: QSOs printed: 1961
F6IRF/P: QSOs printed: 195
IS0/F6IRF: QSOs printed: 105
UT/F6IRF/P: QSOs printed: 25
So from the nearly 10,000 QSO's have been confirmed via the bureau since 2004... (by the way, not all bureaux are slow ! UT/F6IRF/P operation is only 5 monthes old !)

In short: QSL'ing represents time money and energy that I would prefer to use on the air, on station improvments and on travelling; so please:
- Refrain sending 1 card per QSO (only new band/mode) This may be easier for you, but it is a nightmare for me ! (once again I am not interested by cards, they all endup to the trash !).
- Be friendly with the environment and the trees: try to use LOTW or E-QSL...

As shown by this graph, during 2005, I have focused on RTTY contesting, not missing any of the organized contest in this mode... (this chart includes EM5F multi-op expedition for the IOTA contest, thus the high number of SSB qso's in July !)

Results: Of course only a few results have been published, but among the good surprises is the 4th World and first EU-place in the Makrothen TTY contest (together with a 1st world place on the 80m band). More to follow...

CN2WW operation is over ;-(

Over 6000 QSO's in 7days (all already uploaded to LOTW)
2500 QSO's in CQWW on 20m LP - In theory a new World all times record, but most probably a new continental (once UBN's decounted)

Just received the good news...
will be CN2WW in CQWW-CW (normaly SOSB20... or 15 depending on condx)
Callsign is valid 19/11 through 28/11 for peri-contest activity (will be active mostly in CW, maybe RTTY on WARC if there is some demand)

QSL only via EA7FTR (or LOTW)
See you on the bands !

The weekend conditions: better on saturday than on sunday, the 6 hours SSNe dropped to 0 for a couple hours...


Good weekend despite poor conditions.
To be honnest my primary objective was to consolidate my leader place for the DJ3NG's "top-ten trophy", nothing more...
(
http://www.rtty-contest-scene.com/index1.html )
So I focused first on QSO's, forgetting abt QTC's on saturday. When I passed the 1000-Qmark sunday at 08:35z with 24h of airtime, it was clear that my primary objective was met... So I started to hunt the QTC'ers.
Once again noticed that as a EU-stn I would make very few QTC-points, if I did not actively/agresively search for the QTC'ers...very few spontaneous offers - except a few ones from Ukrainian stations, which I had to decline ;-)
But finaly the "non-strategy" payed; Far better score than last year, despite smaller antennas (was at F6HYE stn) with much more QSO's and mults,
and almost the same nr of QTC's at the end ! Once again the SO2R-bonus is obvious here, and QTC'ing only on sunday when the rate is getting low, may not be that crazy...
10 and 15m have been the good surprises of the weekend, especialy 15m better than 20 with this low SSN... 20m closed very early, especialy on sunday, and central and west-US signals strongly affected by auroral flutter.
I suffered from noisy condx (high statics level on 80, local-line QRN on high
bands), making QTC-sending my preferred choice (thanks to all who accepted to grab my QTC's).
Eqt-wise, some troubles with 2 N1MM serious crashes but fortunately without major damages, except 10QTC's and a few minutes lost (next time will put a recorder on a separate PC to recover lost QTC's).
Must also say that a few N1MM features need to be improved for this contest: QTC's on main radio only, no QSO/QTC distinction, no "section summary", saving of QTC's sometimes capricious, received NR's turned to 0, etc... Anyway, it did not work that bad for me, I shouldn't complain...
Thanks to the DARC for organizing, to all for the QSO's and see you from CN in CQWW-CW.

Full contest stats at

This chart clearly shows the important role played by QTC's in the final score... I focused on QSO's on saturday and on QTC's on sunday.

F6IRF News and agenda

- October 23-30 : I have been active from IN87 during a week hollidays on the Atlantic coast (abt 500 QSO's)... Taking advantage of the exceptional weather and temperature , I did an excursion with 3 hours "on the beach" operation from EU-048 (Houat).
Equipment used: IC706, laptop, microkeyer, AT130 tuner, and "spiderbeam" 12m fiberglass pole mounted vertical.
- October 29/30 : A bit more that 100 Q's in the CQWW-SSB... more than enough ! (For me SSB remains the most unadequate mode for contesting !)
- November 5/6 : Took part in the "Ukrainian DX contest" - see
http://lists.contesting.com/archives//html/3830/2005-11/msg00484.html
- November 12/13: Will be active in WAE-RTTY contest...
- November 19: Departure to CN. I have been allocated CN2PD callsign, which I am currently trying to get changed (this callsign has already been used in 2003 and I cannot access qrz.com data)
QSL manager for this operation will be EA7FTR
- November 26/27: CQWW-CW, SOSB20
- November 28 back to France...


My current CN-license.
Hope I can get another one for the new dates, with another callsign...
Inshallah !!!

F6IRF number one!

At the end of 2004 I decided to give first priority to RTTY contesting for the 2005 season, taking part in all posssible contests (22 so far)... So far, some 17,000 RTTY QSO's have been logged since January...






F6IRF number-one on DJ3NG "world contesting RTTY contesting scene" top-list....
Also currently "temporary" number one on DJ3NG's 2005 challenge (remains 2 counted contests)
Only the number of RTTY QSO's is taken into account for DJ3NG's palmares.









Below ,
Also number one on DK3VN's "world ranking list"(official points and places in contests are taken into account) .

(sorry for the cat. mistake on 3830 - sent a correction request immediately but it was not taken into account)


Who could guess that condx would be that good with such a quiet sun, and that 10m would open... even the most advanced prediction software do fail to predict such unpredictable phenomenae.
The contest story
Based on last year and expected conditions, and the fact that it was my birthday, my objective was modest...
Thought it would be nice to reach 1000QSO's. Started very well on 40m with good transatlantic conditions, and the first good surprise came after only 20mn with FR1HZ. However, and as usual at this season, 40m conditions declined before sunrise. 80m was very noisy, and the activity quite low, so I started to fall asleep... I usually don't need any break during the first 24 hours, but I had obviously started the contest already tired. Anyway 268 QSO's was not to bad for 4 hours and a half of traffic on low bands.Came back at 0620 and the first 2 QSO's were ZL2AMI on 40m and NL7V on 20, but did not stay much on 20 when I saw that 15 had already opened to JA. Great JA session which allowed to pass the 500 mark before lunch time... Was again falling asleep after lunch so took another hour nap before the opening of the15m W-window, was keeping an hear on 10m, but FR1HZ was the only station heard and QSO for this first day... 15m declined quickly after sunset, so I moved to 20m for another great 75Q in the 17th hour.
One of the problems of contesting from home is that you cannot dedicate full time to the contest, and you have to make the sacrifice of a minimum of airtime to social and family life... took another full hour break for dinner !
Came back directly on 40m. expecting a few JA's, but only logged JA1OVD in the first hour... was a bit too early; JA opening started 1 hour later. QSO #1000was logged at 22h29 after 18h30 on-air time... Then the rate started to slowdown, and again the bed appeal got stronger, so closed the stations at 00:00z with 1054 QSO's in the log. I came back at 0335, and this time 80 was in better shape, which allowed to log a few NA stations and multipliers, and again the bed appeal got stronger ! Went back for 40mn short sleep around sunrise...When I came back, I could not re-open my windows session... "you forgot youpassword?" damned ! Finally managed after 2 or 3 reboots... then the PC crashed several times before Norton detected a "spyboot.worm" virus attack !
Lost another 40mn there and gained a lot of stress !
At 0800, while CQ'ing on 15m I moved the 706 from 20 to 10m... great choice, I logged 50 QSO's and quite a few mults on 10m... all countries coming with antenna the antenna to east - apparently some multi-hop strong E's, with associated backscatter... until I had to stop, for my birthday celebration - had 1267QSO's in the log !Guess what I received as birthday present: An expresso machine ! ( I am readyfor the full time in the next one!)
The rest of the contest would have been a usual "boring second day" without 10m opening to states... W3MR was the first one on 10m with antenna toward west, quickly followed by a few others in K1 to 4 areas... K4GMH was the stronger and stabler signal for the whole duration of the opening, which I assume is a E's multi-hop, very similar to 6m transatlantic openings... same as last year in CQWW SSB, so it seems to be a speciality of the "indian summer" season... But never heard any VE, though VE1OP had been spotted by a few EU's, which seems to confirm my E's hypothesis: pathes are very localized, and even 100 kms on the ground can make the big difference between S9 and nothing.
I came back for a couple of hours after dinner, focusing on 80m... as usual the 80m activity gets better as the end of the contest approaches... had the pleasure to be called by VK6HD with a strong and clear signal.I finally gave up at 2245z... had to take some sleep to respond to the office appeal on Monday morning !Finally 1600 QSO's for 35 hours of traffic is not that bad... But contacted Nick UX0FF operating UY6F who told me they had passed the 2M points and the2000QSO's...
Wish I could be in better shape for this one and do over 40hours, but it's life, sometimes your body needs a rest, and it is not getting better with years... Has been a nice birthday though!

Total 777 4097378 5273
DK3VN web-engine score: 4,101,726 (dupes removed)

My small domestic simplified SO1R station: IC756pro2 - HB 2x4cx250=500w - 2el TB-yagi@40' - LB dipoles @63 and 66' N1MM 5.9.7 - DX-cluster
Seen from my location Makro-contest strategy can be summarized as: work as many W's as possible!
Nice contest, but somewhere a bit too much "brute force". Must say that I personnaly missed the mult-hunting part and the SO2R fun... what makes RTTYcontesting a bit more than just F-key push. Of course I could have entered the Mult-trx category, but this category really lacks the competitors to make it fun... (and why SO2R if no mult to hunt?)
Anyway congrats to Mike K4GMH for his great score... (I know that I am missing real antennas to compete...). Conditions have been better that expected, but the low bands strongly affected by statics. Once again VOACAP based simulations were far too pessimistic: 15m has been far better than predicted (no JA no W according to pre-test simulations;-). Suffered from local power-line QRN especialy on 15m with antenna to NA...Thanks to VK6HD for the QSY to 80m; I usualy refrain from "moving" stations but this is the best point/QSO in my log... deserved an exception !
My weekend "dummy award" goes to UY8IF who refused to work me on 20, though Iwas claiming loud and clear "YOU ARE NOT IN MY LOG !" (once again: there is no penalty for dupes just work'em all and basta! why this endless/repeated ridiculous behavior ?)
My apologizes to 7X0RY for calling twice, but a remaining bug in N1MM does make callsigns starting with a figure to ever appear as dupe ! (however, except this small marginal bug N1MM worked well...).Thanks "Waldemar & friends" for organizing; Good time-format, but still missing a few participants (indicators: vy large % of 4bands stations + low hour rates despite short exchange).
