Ahhhh, so I've been trying to receive AX2VLB the last couple of nights on WSPR… but no joy (even though everyone else seemed to have success).
Well I was instructed on a couple of things to check and one of which was the balun in my dipole – something I'd not considered. However, when you read the specs for it (it's a Diamond BU-50) you can see it has a passband of 1.7MHz to 40MHz. This obviously means it would be effectively filtering out the 508.1kHz I was trying to receive, plus no wonder there is nothing registered on the S meter down there.
So, looks like if I want to do LF I need a different antenna configuration. I think I really need to get that long wire up I was planning to play with….
On other news though, I did finally manage to setup my HF gear somewhat permanently in my garage last night – and thereby was able to leave WSPR listening all night. 🙂
