European Es (Sunday)

It looks very promising with lots of Es to central Europe.

10m QRP WSPR (Sunday)

My 500mW 10m WSPR beacon was re-synced to internet time at 0855z. 

UPDATE 0920z: In the last hour alone 27 stations have spotted my QRP 10m WSPR beacon.

UPDATE 1346z: 33 spots of me today.

FT8 versus WSPR

My impression is that I get better results on 6m FT8 than I do on 10m WSPR.  

Yes, on 6m FT8 I use 2.5W whereas recent tests on 10m WSPR have been at 500mW. 

Now, FT8, is supposed to be less sensitive at picking up weak signals than WSPR but WSPR needs almost 120 seconds whereas FT8 needs just 15 seconds. I suspect FT8 catches more, shorter, openings. Also, I suspect there are more FT8 users.

Someone else trying my designs

 It is always good to see others trying their hand at my designs. DX Explorer has a video of him breadboarding my 2 transistor 80m transceiver. My designs are always a starting point. Pretty sure you will be able to improve them!

St Ives - NOT amateur radio


 This was St Ives (near Cambridge) earlier this week .

6m QRP FT8 (Saturday)

My 2.5W to the V2000 vertical omni antenna has been on since about 1940z. 

UPDATE 2035z:  28 stations have spotted me.

UPDATE 2146z:   125 spots of my QRP FT8 today, after a very late start.

10m QRP WSPR (Saturday)


My 10mW 500mW WSPR has been on since we got back from London earlier. So far, 7 stations have spotted me.

UPDATE 2037z:   24 spots of me, mostly Es.

UPDATE 2212z: 39 spots of my QRP 10m WSPR so far, after a late start.

European Es (Saturday)

 Whilst I was in London seeing an Australian friend who had a stroke in the last 30 minutes of a flight (he is in hospital) I gather European Es has been very good ... and I missed it!
