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!

10m QRP WSPR (Friday)


My 500mW WSPR beacon is on again and there is plenty of Es about.  50 stations have spotted my QRP beacon in the last day with the furthermost Brazil.

UPDATE 1142z:  58 spots of my 500mW 10m WSPR this morning.

UPDATE 2140z:  776 spots of my 500mW 10m WSPR in the last day.

6m QRP FT8 (Friday)


Stations that spotted
my 2.5W 6m FT8 today
My QRP 6m FT8 is on again. In the last day, I have been spotted by 512 stations on 6m, with several in Newfoundland, Canada. I suspect the latter were Es.

UPDATE 1135z:   449 spots of my QRP 6m FT8 this morning. Mostly Es.

UPDATE 2125z:  557 spots of me today.

Early Es

 Today seems to be a good Es day with lots of stations across Europe spotting my QRP on 10m and 6m already at 0631z.
