Robert, for some reason the Rangemaster is not effected by RFI from nearby FM broadcast in the 100 milliwatt range. After alerting Procaster to the problem, they were able to recreate it with a remote control used for model aircraft. I was told part 15 rules say you have to accept such interference.
Just plugging an XM radio into a Procaster, will send it into self osculation, I know it’s not just the Procaster. Many Sstran users report the same problem, when it is used near an FM transmitter like the EDM.
One fix is to use an isolation transformer in the audio path, and ferrite beads on both the audio & power pack. sending a balanced signal over shielded cable helps a bit too.
Out of the box as shipped, plug your ears if you are near an FM transmitter when you turn it on!
The Panaxis AM transmitter for some reason is completely immune to RFI. Now the Panaxis FME 500 is a different story, it can’t be operated around a 40 watt AM transmitter or it goes bonkers.
