Hi Brian,
you have just solved a long standing problem I had with CW not working for me too!
I have a U3S Receiver. Is there also a trick to make it stay in receive mode continuously? I use it set for 'RX' mode but it only runs for 2 minutes. I have to run multiple 'RX' cycles but it has breaks at the end of each 2 minute cycle.
