10m and 12m QRP WSPR (Tuesday)

Today I am trying 2W frequency hopping WSPR on 12m and 10m.

UPDATE  0938z: Plenty of spots on 10m, and 2 stations spotting me on 12m with the furthest Brazil.

WSPR and frequency hopping

Yesterday I tried WSPR frequency hopping at 10, 12 and 15m with 2W. Furtherest was Antarctica. This could be really useful. 

24GHz radar module

 Yesterday I mentioned a very low cost 10GHz radar module ripe for hacking into a 10GHz WBFM transceiver. I see there’s a 24GHz version too! If only I was fitter 😢. 

Outside St John’s, Cambridge

 This was outside St. John’s College in Cambridge yesterday.

Sunspots - Tuesday October 14th

 Solar flux is 141 and the SSN 122. A=23 and K=1.

10GHz radar module

These are available very inexpensively (just £1.25 on Ali-Express!), so I am wondering has anyone adapted these to 10GHz wideband FM (WBFM) transceivers? These look as if someone will "hack" them!

WSPR and band hopping?

As we approach declining sunspot numbers, many just give up on the higher HF bands. 

Often, these bands are "open" (just listen to the CB band next door to 10m!) whereas a lack of activity is the real cause. Especially on N-S paths the bands are open far more often than we think. 

With WSPR we can check how good our higher HF bands really are. WSPR is widely monitored so we could send WSPR on several bands in sequence into an antenna that covers these bands (like an EFHW) and watch who spots us around the world on various bands using WSPRnet.

FT7 Yaesu transceiver

My very first HF commercial transceiver was the 10W Yaesu FT-7 bought second hand in the late 1970s. 

It was a great rig and allowed me to work 10m QRP DXCC with 10W SSB back in the 1980s. This was with low wire dipoles and a CB  half wave antenna. 

By comparison with modern rigs it was big but it was very quiet on RX. If I had to rate it I would give it 11/10. In all my years it was the best transceiver I have ever owned. No synthesisers, no memories, fully analogue …just great.

Sunspots - Monday October 13th

 Solar flux is 143 and the SSN 127. A=29 and K=4.

Times Radio

Quite often, I watch Times Radio on YouTube. They interview some interesting characters on the world stage and often, their views are full of incite, even if you may not agree. 

In my view it is worth getting world news from several sources as often one source  may be biased.
