The HW-16 is mostly a transceiver in name only with very little commonality between the transmit and receive sections and for the warble to appear on both transmit and receive the power supply is the overwhelming favorite as the cause.

That does sound like the most likely cause, but don't overlook the possibility that the warble may be caused inside of whatever you are using to monitor your signal.
