WSPR, JT65 and other screen shots

Here are some screen shots that should be largely self explanatory but I'll add more if I think necessary.

1296.500MHz WSPR 



The 220km path on 23cms
WSPR & JT65 at he same time on 30 metres
The relocated GB3USK beacon on 23cms not to strong with me
200 mW heard in Antarctica

A good day on 70MHz

WSPR setup

Here's my WSPR setup.
Two Metres: home brewed hybrid SDR (has IF at 10.7MHz) nine element Tonna.
Four Metres; home brewed SDR loosely based on a design by WB6DHW and a two element HB9CV
 Have the same arrangement on Six but not used it to date.
Can also receive using home brewed TRX with SDR IQ output from 160 to 2.
Antennas are 80 metres from the house with amplifiers and pre-amps in shed below the mast.
Keeping power low has been no small challenge!
