I have a K3 that was working fine one day and then the next day it would not
transmit or tune. We had no weather and I unplug the antennas and power supply
after each useage.
When I would try to tune I would get - - on screen..

Thanks Mike; VOX was the answer...

I am using an Alinco DM-330M power supply. Across the output of the power
supply I have a 26 AH battery. If the AC power quits I have many hours to shut
down the K3.
I have the output of the power supply set to 13.8 V. Should it be slightly
higher? How much?
Sometimes I do not even turn on t
Keep in mind that I've powered down my K3 many, many times by pulling the
plug, not hitting the POWER button, with no problems whatsoever.
That's why I asked Wayne about it when the issue came up before and he said

Personally, I don't see that as a major jeopardy. A UPS is fairly cheap
(certainly in comparison to a K3), kicks in within milliseconds, and
should easily give you enough time to do an orderly shutdown. Most

Joe,
Many thanks for your help.
I had been toying with the idea of buying a K3 for use at another QTH, but
there the mains supply is not 100% reliable. If bad things can happen if the
13.8V supply shuts down as the result of a mains outage, that is serious.

Hi Joe,
Give it half a second (literally). In practice it should never take
more than 100-200 ms, but this will give you some margin.
I'll also note this in the Owner's Manual.

Just felt that a word of reassurance may be worthwhile. My older K3 (#228) has
now worked about 35000 QSOs in Africa with appalling power problems - switching
off the rig before the PSU would be a luxury indeed. Also losing power while
transmitting has been quite frequent (and unavoidable). The
From the owners manual (page 44 in rev D2):

A remote-control system can pull the POWER ON line to ground (ACC
connector, pg. 18) to turn the K3 ON. To turn it OFF, the controller
must send the K3 a "PS0;" remote-control command via the RS232
interface, then deactivate
cord or shutting off the supply.

Ron,
Is there any interface available on the K3 which would allow an external

Sid -
Any good computer UPS will keep the K3 running for 32 seconds. I wouldn't
transmit during that time, however, unless you allow for that in your UPS's
capacity. I recently bought a large-capacity APC unit for our plasma TV to
isolate it from the mains (Florida is lightning capital of th
This brings up the question of what is a good UPS for the K3 and usually
attendant computer?
I live in a rural area and I have the entire house on a 15 KW backup
generator but it requires 32 seconds to kick in. This morning we lost
power for 5 seconds and I was fortunate the "brains" didn't get
Glad to hear it was such an easy fix, Maarten! But you do bring up an issue
that has appeared on the reflector before: the K3 *wants* an orderly
shutdown sequence to avoid unusual and troublesome issues.

Thank you Dave for your reply, but it was a entirely different "problem".
I'm embarrassed like you won't believe. Before posting my problem on the
reflector I thought I had checked everything to make sure that is was a
genuine problem. After an hour of doing something else, I turned the K3 back

I had a similar "oops" with my K3, a faulty cable/adapter on the KEY
input socket caused my K3 to go to full CW carrier output on 6m, in a
hurry to stop the transmission, I turned the power supply mains off as
the K3's controls seemed to be locked... Big mistake, the uncontrolled

Today I was playing with my K3 AGC settings to learn more about them. At
some point I had placed my Heil Pro Set Plus on top of the K3. A strong
