KD4APP listening to AO-40 using a DSS dish


The temporary setup outside (left) and inside (right). Outside is a 2 1/2 turn helix and a 13ULNA preamp. Inside is the power inserter for the 13ULNA and the TranSystem 3733 converter and the 3733 power inserter (not shown). I was able to copy telemetry with good CRC's and voice QSO's all the way out to maximum range at very low squint angles. More tests to follow. See the same setup with a 5 1/2 turn helix here.
