My mcHF has suddenly developed spurii every 1.5khz high and low of tuned freq. They are big and strong and quite numerous. Pretty sure its the driver...i isolated the pin diode change over and the PA too. I changed the PA gate R from 220 to 100 ohm.

Im at a loss really as to why its developed and thus how to fix the driver. Anyone else had this?
