G3TXF : CQWW RTTY Contest : 40m SOSB (A)


The antenna used for the 40m Single Band (Assisted) entry in the CQWW RTTY Contest was a pair of wire dipoles at right angles to each other at about 80ft (25m) above ground, each fed separately through baluns.

The rate graph shows that there were only two of the forty-eight hours in which zero QSOs were made. There were also a couple of hours where there were low numbers. Overall with a total of 1,437 net QSOs, the average QSO rate during the full 48 hours was just on 30 QSOs per hour. There was active operating during 44 out of the 48 hours.

Although N1MM was used for contest logging, the above images come from WinTest, where the graphics are generally better. The Cabrillo exported from N1MM was imported to WinTest. During the contest the GRITTY decoder was added to the MMTTY and 2Tone decoders already in place. The appalling conditions during the contest made decoding of weak and fluttery signals very difficult at times. Having all three decoders running in parallel really helped, particularly the last minute (during the contest) addition of GRITTY.

The table shows the number of stations worked in the "top twenty" countries. The only non-EU countries here are W (223), VE (24) and PY (16). Although there were 48 European Russians worked, there are only 8 Asiatic Russians.

European QSOs were 73.8%, followed by North America 18.7%, Asia 2.7%, South America 2.4%, Oceania 1.9% and Africa 0.6%. The relatively poor conditions would explain the proportionally higher number of EU QSOs.

G3TXF logged into the Contest Online ScoreBoard for the first time ever during this CQWW RTTY Contest.

The screenshot shows the four SOSB-40m-(A) entries that were logged in. As well as G3TXF there was HF9M, K9OM and PY4AZ. One immediate side-effect of logging into the Contest Online ScoreBoard was the competitive impact of seeing another station in the same category with a similar score.

Had HF9M not been on the ScoreBoard and had he not also been actively taking part in the contest, G3TXF probably would not have put in the number of hours that he did in order to try to build his own score!

The competitive impact of the ScoreBoard will probably lead to increased competition and therefore bigger scores in various contests. Connecting into the Contest Online ScoreBoard from N1MM was remarkably simple.

In the category above "SO-40 HP (A)" in the screenshot there is the SO-80 QRP (A) category, which includes Ian G3WVG operating as M5A on 80m QRP. Although there are many hundreds of scores listed in the Contest Online ScoreBoard, you can adjust the view to show just those categories in which you are interested.

A few days before the CQWW RTTY Contest, we received a visit from Mike G3SED. Here Mike G3SED (l) and Nigel G3TXF (r) are seen correctly "social distancing" by means of an antenna element over 2m in length.

In the background is the trailer tower supporting the two 40m wire dipoles used during the CQWW RTTY Contest.

The CQWW RTTY Contest website has a searchable scores database going back to 2007.

The data for these entries by G3TXF have been extracted from that excellent source. CQWW also has similar searchable databases for CQWW CW and CQWW SSB. They are veritable treasure troves of interesting data.

A further indicator that conditions were down this year, was that this year's score was not significantly ahead of the score made in 2017. However in 2017 the CQWW RTTY entry was UN-assisted and this year it was Assisted.
