There was a group which disliked his use of quaternions so he was forced
to rewrite the system into other systems. Most of the work was carried

Certainly you could try re-seating that board, but I would be more
inclined to look for something on that board which could cause a short.
Re-seating will often correct an open circuit condition, but a short to
ground is a different animal. If you find any bits of conductive

Hi Don, yes, I have checked this - there is nothing connected to the
ACC connector or the RS232 port when this occurs.

Jeff,
It sounds like the Remote Power ON signal (on the ACC connector) is
becoming active for some reason or another. If anything external to the
K3 or internal is pulling ACC pin 8 to ground, the behavior will be as
you describe. If you have a cable plugged into the ACC connector it

If you are in CW mode you cannot select from front to rear or line in.
The display does tell you this but only if you are paying attention! I
am not sure why the radio cares what mode I am in when I want to change

My 43' antenna works very well on 160 and 80 as I have reported. In fact,

Hi
I have an 1.8kHz filter that I'd like to swap for a 400hz one so I can

If you have one and would like to swap, please email me off-list!

What you are seeing is the monitor output, which is mono (both

in both displays, adjust the MON control to zero. Using MMTTY, you will

No, 43' is 5/8 wave on 20 meters (984/14.3*0.625 == 43). That is
the point (well, 0.64 wave if you want to be precise) that the
first lobe has maximum radiation in a vertical. That the 43' or

Good question, that has never crossed my mind; but now that you mentioned

One variation on that. While your technique of using the wide filter to
listen on the DX frequency is a good one, the lower cost 2.7 kHz filter
accomplishes that just fine. The
This is the technique the K3 Utility's terminal program uses. EOT is sent
when the ESC key is pressed, when the input buffer empties, when you toggle

Yes, I would recommend having both matching filters in your subreceiver.
In my main receiver I have filters for 13/6/2.8/0.4 kHz. In the sub I chose
only 2.8/0.4 kHz filters and am happy with the choice. I've found no need (so
far!) for AM & FM filters in the sub.

If you are going to use it for Diversity RX, the best option is to

and 500 on the sub, an
