Thanks......Gil

You seem to have a classic example of the RFI issue but I don't think
you can attribute it specifically to tube or solid-state technology
inasmuch as you can attribute it to the tighter rf packaging of more
modern rigs. Nothing about tubes per se makes them more prone to problems.

That said, while RF shielding integrity of a commercial xmtr/xcvr has
generally improved over the years, the RF integrity of consumer devices,
and that includes telephones, has gone down the tubes (no pun intended)
since Nixon went to China!

A poorly shielded xmtr in the ring with a cheap offshore home electronic
device is a guaranteed KO for both of them.
