For my local and not so local chaps
At 1630Z Changed to WSPR2 Tx
carrier appx 506.5kHz , 0.5W 100% - to receive WSPR2 use "dial" USB
505.00 kHz Antennae is 1/4 Y loop
This continues to be a shake
down of the Ultimate2 Hans Summers QRPLabs tx as the future driver for the main PA.
Its GPS's refd and appears highly suited (and can be built in a an
evening for not a lot of moolah) does WSPR2/15/QRSS/DFCW/CW/FSK/Helli
and more. Ive added the second PA transistor and added a few more turns
on the output transformer and is basically flat (if using the correct
plug in filters) from 137k to 21MHz (or more). Love it.
Ill also post this on Blacksheep so apologies now for the dupes
