Practical Wireless QRP Contest

In this contest I worked just 3 locals when active. I was quite close to the bottom in the results. 

The last time I seriously entered this contest (30-40 years ago?) I was using 1W AM and ran a large parabeam antenna /P from a good QTH.  

This time we could not operate /P and only from home. My antenna is just the big-wheel omni antenna.

70cm activity contest

Unless I am mistaken, this evening, starting at 2000z, is the 70cm activity contest organised by the RSGB. I use 10W and the 2m big-wheel. As yet, I have not seen an email reminder. I usually stay on for less than 1 hour, although the contest lasts 2.5 hours.

UPDATE 1815z:  Guess what? The reminder email has just arrived.

2m FT8 QRP

At 1433z, I QSYed to 2m (FT-817ND) FT8 with 2.5W to the big-wheel omni antenna. At 1445z, 3 stations had spotted me with the furthermost being G7RAU (461km) on the Lizard in Cornwall. So far today, just 1 station spotted and that was G8VDP (182km).

UPDATE 1520z: A quick look at G0LRD's grabber showed my QRP signal a little down on normal, so I have increased the ERP just a little by adjusting the SignaLink USB. See http://82.71.9.63:8080/cap/ . Now being spotted by 7 stations in 3 countries with the furthermost being EI2FG (565km). Also spotted by GI6ATZ (479km). If I got these ranges on 2m SSB with QRP I would be totally amazed. On 2m FT8 this is daily.

UPDATE 1800z: 18 spots of me so far today.

6m FT8

OK, I must like white noise! 

For a change today I am on 6m FT8 QRP with 2.5W and the V2000 vertical omni. It would not surprise me at all if the whole day passes without any spots. Outside of the Es season people often leave the band. With FT8, there is some chance.

UPDATE 0945z: Well, I have already been spotted by G0PQO (50km) at -21dB S/N. This was almost immediate. So much for the whole day without spots!

UPDATE 1035z: I have been spotted by a second station! M1ABK (70km) at -18dB S/N.  I suspect this is ordinary tropo i.e. these stations, if active, would spot me most of the time.

UPDATE 1430z:  1 station has spotted me and I have only been spotted by the 2 G stations earlier. I think I shall QSY to 2m FT8 shortly.

OT2CARE

This is a special Belgian call that I spotted this evening on 2m FT8. At first I wondered if it was a pirate!

2m FT8 QRP

At about 1645z I QSYed to 2m FT8. So far (it is now 1652z) 6 stations in 3 countries have spotted my 2.5W to the big-wheel omni antenna.  On RX no-one yet spotted.

UPDATE 1757z:  9 stations in 5 countries have spotted me so far on 2m FT8 today with the furthermost being GI6ATZ (479km). On RX 3 Gs spotted so far.

UPDATE 2055z: 18 stations have spotted me and I have spotted 8 stations.

Repairing the "better" 10m loop

This afternoon, I tried in vain, to mend my "better" 10m loop antenna. I failed. 

Before, there was a distinct peak when tuned and the SWR dipped significantly on resonance. Sadly, just a few minutes of soldering work left me totally exhausted and giddy. I shall have to try again another day. After about 10 minutes of physical or mental work I am just knackered. Whether this is my stroke or just old age I do not know.

At the moment I am still on 15m FT8 on the "poorer" loop.

Covid vaccine - NOT amateur radio

There is news today of a Covid-19 vaccine. Already the stock markets have reacted positively. Hopefully this will be the first vaccine of many. 2020 has been a nightmare year. Let's hope 2021 is better.
