My thanks to Markus and others in debugging my set up here - my first night of receiving much for a number of weeks with nearly nightly Aurora - last night for some reason was a little better  - Fair QRSS signals from Bob XEB on the East coast - I don't think Bobs pastes it but heres a link on the loop - a little clearer than the probe

On 475kHz WSPR2  some decodes from XXM on 630m at around 4600Kms on my K9AY/East  - Ive just uploaded them


Opds -  On 137 I ran (or run) two instances  on two different antennae systems  :- kind of interesting - Id had time to cal the loop receiver sound card (first table) but not the L400b sound card at 12K but I think its pretty close -  Ive added the Opera decodes. Note the loop isnt pointed at BDQ but was generally NE/SW - I know its not a huge range but even on this path the Aurora etc can make for some challenges and this was a good shakedown.
