Thank you Stefan.
I could try two microphone transmitters back to back as I have only one
1:1 isolation transformer and again I might try a short range LED link
although these tend to have linear modulation and the dynamic range of
digital radio signals seems quite high.

Hi Hugh,
Maybe there is some improvement when trying 2 isolation transformers
and grounding the TP cable in the center?
The other solutions will not work well i think, because the dynamic
range is not high enough.

To avoid having laptop running in the shack, which occasionally
produces some QRM, I can send received audio from the shack to a
desktop computer in the house on a twisted telephone pair. This works
but any wire connection between shack and this desktop introduces
some spurious signals on 136khz even if I use an audio isolating
transformer.
