Any hints on why this happens, and the best way to cure it?

I can think of two causes of this. 1) They are designated as unprotected
radio devices and operate in a radio band which has several licensed
user (MoD, amateurs, etc.) permitted to use hundreds of watts and lawful
transmissions by these users causes it. 2) If the receiver is close to a
PC

About 5ft, but it's always this close and the problem is sporadic not
continuous.

then RFI from it could be raising the noise level and making the
wanted signal harder to detect. If it's due to a PC then moving the
three items should solve the problem; if it is due to other licensed
higher power transmissions moving the two thermometer parts might
improve the performance, if not then there is not much you can do other
then moving.

I think I'll just have to put up with it.

Thanks anyway.
