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 that it is *possible* for data to be corrupted *if* a write process is going on wh

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 modern UPS's link to the computer via USB and will provide an orderly shutdown to t

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. 73, Geoff GM4ESD Joe Planisky wrot

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. 73, Wayne N6KR On Jun 7, 2009, at 9:45 AM, Joe Planisky wrote: > From the owners manual (page 44 in rev D2): > > "

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): "Remote Power On/Off 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

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. An orderly shutdown requires the POWER button be pressed on the K3 before the power supply is

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 on
