I seriously doubt this is an RF issue. TV is all digital and has no discrete
audio carrier. TV RF interference would sound like white noise. This sounds
more like an audio ground loop of some sort.

If the K4 is *off*, then there's no active circuitry involved. However, the
headphone plug-insertion detect circuit may involve an IC downstream that could
include a schottky diode junction -- a potential way a very strong signal could
be rectified right at the radio end of the cable. We'

My CM500 died on me, looks like the electret element … I replaced the set with
a Koss SB/45
which was cheaper and quite comfortable and plugs into the K3 as well (K4 too).
The price of the CM500 had doubled up here in Canada for some reason, so the
Koss looked more attractive.

Interesting, and possibly related (and I kind of forgot till I read Jim’s
email).
Noticed that when the antenna are disconnected, and the K4 turned off, I hear a
local TV station in the headphones… Never happened on the K3.
Headphones connected to the rear panel jack.

I have to temporarily re-arrange my amp table to troubleshoot one of my two

come on it should direct the heatout of the normal top vents. I
It seems to depend on the headset being used. I have an IC-705 (my K-line is
packed in storage currently) and have tried Bluetooth with it. Using several
different BT headsets (Bose QC, Apple Air Pods, Avantree) it was an utter
failure on CW. However, I recently got an Srhythm NC35 noise cancell

The important (and killer) issue with Bluetooth is latency when you try
to run CW. The delay makes it impossible to send with any form of bug,
paddle, or straight key. The delay

I was hoping the K4 would have BT audio, but it doesn't. So the next
best option would be to send the sound card audio to BT in a computer,
linked to the aids or headset... I don't hav

I’m gonna try ferrites next.
