[OT] Strange noise

[Vic Rosenthal]

Has anyone experienced this:

When I let the key up after sending a dash or two there is a "static
crash" which seems to start AFTER or just as I stop sending.

- It happens on various bands, but seems to happen more often on 30m or 20m.

- It happens whether I am running my K3 barefoot or with a kW amp active.

- It is intermittent. For example, this morning (6 am) it was bothering
me on 30m. Now (8 pm) I can't make it happen.

- On the P3 it looks like a series of horizontal lines extending across
the display. Sometimes it is very short in duration, but sometimes it
can go on for several seconds. You can imagine how annoying this is in a
DX pileup.

It is as if my RF is triggering an arc somewhere.

Could a CFL lamp do this?

I should have added that sometimes what appears to be the same noise
occurs when I am NOT transmitting.

Could also be bad points on the RX side of relay in the RX path somewhere.
