137kHz tests with an E-field probe mobileP

Before my stroke, I did some mobile tests on 137kHz QRSS QRP using an EFP
with an FT817 RX. Results totally exceeded my expectations. After I
reached 24km, I gave up. This was with a very low ERP.

10m Phaser

Because of my poor building skills, a very kind amateur in Scotland has
built and tested my 10m Phaser kit. All being well, it should be back this week.
The Phaser is a QRP SSB transceiver, for FT8 mainly, producing about 3W
pep. It is a phasing rig designed by Dave Benson K1SWL. It should allow
the "big rig" to be used for other things.

10m FT8 QRP (Monday)

After a brief session on 2.5W TX I have been on RX the rest of the time. It
is now 0840z, and just 1 G spotted and nobody spotted me.
UPDATE 1037z: Just 3 stations spotted so far. The 2 from mainland Europe
were probably Es, but could have been aircraft reflection. At this point yesterday, things were better.
UPDATE 1917z: Only 7 stations spotted. All in Europe. A bad day.
UPDATE 2058z: 10 stations spotted with the furthermost LU8EX (11209km) in Argentina.
