This afternoon I fixed the problem with RX desense by adding a relay to switch the RF input and to turn off the PA supply when not on TX. It has fixed the RX sensitivity issue and added about 10-15dB to RX sensitivity using the transverter. PA0A was about 30dB S/N on QRSS and DK7FC about 20dB S/N on QRSS. M0PPP is now a better signal with me too on WSPR. The TX is still running at 500uW ERP and GW0EZY is copying me in mid-Wales OK (251km) this evening on 137.5kHz WSPR.
