Steve,
It can take a while to be picked up by a grabber. Things to check :-
Your beacon is transmitting within the 100 Hz QRSS sub band of the ham band you have built the beacon for. I guess 30 meters is your band. The deviation should be set for about 4 Hz.?
You are not loosing power by transmitting into an inefficient antenna/tuner arrangement. I have had good results connecting my QRSS Labs kits into 50 ohm coax then onward into to a horizontal half wave dipole in the garden.?
There may not be grabbers on-line for your band, they tend to come and go as people change operating modes. Also propagation conditions might not be good.?
QRSS is a bit like fly fishing....you have to be patient!
