[BVARC] Any uSDR users in BVARC?

[Daniel Poirot]

Hi Steven,

I just got on the 10, 12, and 15 meter qrp calling frequencies with my
EFHW. I can hear a few folks but got no response to QC QRP.

I am itching to get on the 80 meter rag chew. It’s time to build Big John’s
loaded dipole!!!

Thanks for the pointer.
