On a recent cross country, the 530 was noted to have a receiver
desensitization problem. The companion 430 heard just fine and both
transmitters were said to be transmitting well by ATC. I have a radio
telephone license and was a former broadcast engineer. This
installation is new with new coax and old antennas. I am told some
issue may exist with WAAS radios. Any confirmation or information on
this?
