At about 1610z I QSYed to 70cm FT8 with my 2.5W and the 2m big-wheel omni antenna. No spots.
UPDATE 1914z: No spots, so have QSYed to 630m QRP WSPR.

10m 500mW WSPR TX
UPDATE 1513z: I have turned off the PA in my beacon. Even though it will report as 0.5W (programmed in), the actual output is 0.5mW (500uW).
UPDATE 1600z: No spots since turning PA off.
2m 2.5W FT8
My 2.5W FT8 (using the big-wheel omni antenna) is now on 2m 144.174 MHz. So far 11 stations have spotted me.
G0LRD has a monitor (see attached). This is about 25km away and is a good check that things are working and the signal is clean.

UPDATE 1422z: 19 stations in 5 countries have spotted my QRP signal on 2m FT8 today with the furthermost GI6ATZ (479km). See map. This is too easy too!
UPDATE 1528z: Interesting that I am only spotting 5 UK stations. My RX is working properly, so this suggests low activity.
New challenge needed
HF bands present no real challenge. Recent microwatt tests on 10m WSPR have been fun, but I need a new challenge.
My 2.5W 8m FT8 signal has been received in most of the places I had hoped for, and this is not likely to change until there are a few new countries on the band. At the moment I am inclined to ask for a new 8m permit from April 2024 - April 2025 even though I have to pay to do research, which I find utterly stupid!
Later today, I may QSY to a VHF band FT8 as this is "different" and not something I have tried for a while.
8m going "off the boil"?
In recent days, 8m seems to have lost its attraction a bit.
The FCC does not want to renew access to the band to USA stations and F2 has probably peaked for now. The main Es season in the northern hemisphere is long over and even 6m has been good for F2 DX. At the moment, I have moved down to 10m FT8, although this is really no challenge.
We could definitely do with more countries legally TXing on the 8m band. Even just CW, FT8 and WSPR only at low power 40.680 - 40.685 MHz would be a start. As this would be within the ISM band I cannot see this should be a problem.

How efficient is my earth-electrode "antenna" in the ground on 630m?
My best comparison is with Jason M0NYW who is using the same G3XBM transverter, but I believe a more conventional antenna. He is also reporting his ERP as 10mW. Jason gets better results that me. In the last 12 hours he was spotted by 39 stations, whereas I was spotted by 16.
How much difference is there? Clearly, he is getting better results, so his antenna and ground are better. Most of my reports are quite close to the limit. Also, for some stations, the local noise can put a stop to very weak signals being decoded. When near the limit of decode, a few dB could make a great deal of difference.
So, it is very hard to say how much better Jason's system is than mine.
All I can say is a more conventional setup is better. What I can say is the earth-electrode "antenna" in the ground does work and is just about invisible.
10m QRP FT8 (Saturday)
My 2.5W 10m FT8 was turned on about 0915z. So far, 10 spots of me by what looks like single hop F2. For some reason PSK reporter was not reporting my spots. I have restarted WSPR-X. Since restarting, I am getting spots from all over the world appearing on PSKr.porter.
UPDATE 0950z: My 10m QRP FT8 has been spotted by 26 stations and 82 stations spotted here.
UPDATE 1033z: 57 stations have spotted my 2.5W and 175 stations have been spotted here.

630m QRP WSPR (Friday)
My 10mW ERP from the earth-electrode "antenna" in the ground was turned on about 1855z. So far, 2 UK stations have spotted me.
