IT's hard to figure how a 1750 tone would control a repeater on HF.
And, I doubt that the system is a true repeater. Possibly, it's a -re-

immediately re-transmitted. An unattended system like that would not
be permitted
I *think* I recall reading about a freeware computer program that would

Hi Folks,
I posted a query about K3 Serial ports a few months back - we could not
get the K3 to work properly with the RS232 connection. It turned out to
be a fault with the sound card, which took out the serial connections.
When I first built the K3, I bought a cheap Prolific USB converter,

USB uses differential signaling. Your problem may not be conductive noise, but
instead it could be radiated directly from the adapter, where the ferrite won't
help.
KeySpan makes a USB - serial adapter that is pretty much noise-free. Its model

else. I recently discovered that if I disconnect my logging program (so it
is not directly controlling my K3) it will reduce noise level on 15m, about

First of all: Please send emails via the Elecraft mailing list only as plain text. Your

The first bounding factor is the internet provider. For example AOL cuts the subject line

Sending as 'plain text plus HTML' format will also get through the server. HTML
