After a long pause start wispering again (but only listening)

Yesterday I started receiving in WSPR again after a long pause of not being active in this mode. Unfortunately I only could be active by receiving in case of some "internal problems" with other rf-equipment nearby my wire-antenna.

Maybe I get my pappradio running again with wspr - at the moment it wouldn't receive any signal in WSPR... Must be a problem with Fiq-frequency or something with "swap i/q-channel" I think.

It's very difficult to find the cause of this but I am sure I would find it some day.
