[Test-Equipment] RF spectrum analysis

[Tom Frobase]

I have a great one, I invested $220 in an Alfedri SDR radio and I use Simon
Browns SDR-Radio allows concurrent reception of 500KHz of bandwidth
throughout HF with a signal to noise ratio -120DB and it will record 500KHz
at one time as well ... tom, N3LLL
