OK, I built my transceiver (20m QCX from QRP Labs, build notes here). It seems to work -- I can listen to people, copy CW when it's slow enough, etc. I was even able to see my (very faint) signal on one of the WebSDRs (in Virginia, and I'm in Baton Rouge, LA, so that's pretty cool!). I tried sending CQ some, but I know I'm a really faint signal. I'm probably getting something like 2W out of the antenna (after feed line and matching loses), but it's what I've got until I can save up for something better (going from 12V to 16V might help...). I thought another good test would be to see if I can show up on RBN. Despite trying a bunch of times on different frequencies, and with the automated beacon feature on the QCX so I know it's not my bad straight key timing, I don't get anything. I've tried sending "TEST KI5FXG", and "CQ TEST KI5FXG", which I think should work according to the docs. Is that right, or should I be doing something else there? And given that I'm a weak signal, how do I know when is the best time of day, best frequency, etc. to maximize my chances? Is there some special juju I should know for the 20m band? Thanks!
