Re: [Elecraft] K3-Front panel shut down question.

No problem to shutdown K3 from the PS during normal operation, except that the last used frequency and controls wouldn't be memorized. No chance for any hardware or software trouble. The UPS or battery only would allow you to finish off the QSO, no other benefits. Even the interruption during FW up

Re: [Elecraft] K3-Front panel shut down question.

I would not have thought that this is recommended, Val. The K3 is a 'computer'. Do you also switch your computer off at the supply without closing Windows down? 73 de David G4DMP In a recent message, Val writes > >No problem to shutdown K3 from the PS during normal operation, except that >the

Re: [Elecraft] K3-Front panel shut down question.

David, I would switch my computer off at the supply only if it, the OS and the other software were designed in such way, that the hard switch off wouldn't cause any harm. We all know that this is not the case with the PC and Windows. K3 however is different. Most of the modern house appliances

Ed, Can I suggest a work-around while you are waiting for the K3 memory editor to be changed. Note that what I see in the K3 Frequency Memory Editor is just a selection of DATA mode - I do not see the selection of the data sub-modes nor the selection of which sideband is to be used in DATA mode

Re: [Elecraft] K3-Front panel shut down question.

The danger with the K3 seems to be if power is removed while it's actively writing new data to memory. Early in the K3 program several people who switched power off at the supply quickly reported finding the firmware "corrupted" in various ways upon restoring power because of that. Certainly no ph

[Elecraft] K2 volume

Hi, I’m still trying to pin down the cause of the low-ish volume of my K2 (s/n 6905), which seems to be something occasionally reported with this transceiver. Dave White, VE6DRW, recently sent me the documentation of the AGC mod to try. (Thanks Dave for digging it out for me – I tried

Re: [Elecraft] K2 volume

Hi Ian, Do you have access to a RF signal generator, or can you build the crystal oscillator source shown in the troubleshooting section of the K2 manual? I've found the receiver signal tracing protocol described there to be helpful. The RF probe supplied with the K2 is useful if you have a good

Perhaps a solution can be found in a WestMountain Radio product called a PowerGate. See: _http://www.westmountainradio.com/content.php?page=dc-power_ (http://www.westmountainradio.com/content.php?page=dc-power) It may be what you're looking for. Bert, N4CW __

Re: [Elecraft] K3-Front panel shut down question.

But first, before plugging the K3 DC supply into any UPS, make sure the UPS has true "Sine Wave" output and is not "Pseudo Sine Wave" when on battery power (or when creating AC from its built in voltage converter circuitry). Your 12v supply's capacitors may clean up a lot of the hash and harmonics

Re: [Elecraft] K3-Front panel shut down question.

I'll repeat W2CS suggestion, get a UPS, then plug the K3's power supply into the UPS. Since you are trying only to allow yourself to shut down cleanly, you can get the smallest capacity, and therefore the cheapest version. It will handle the K3's RX current for quite a while, even with a small UPS.

Re: [Elecraft] K3-Front panel shut down question.

Someone also mentioned that the UPS might generate some hash - BUT that would only be true if the AC is removed from the UPS. Under normal conditions with AC present, the inverter is not active. It was not the initial question, but -- if you want to keep transmitting after an outage, you will

Re: [Elecraft] K3-Front panel shut down question.

Not necessarily true -- I had an APC UPS that created continuous 60Hz-flavored hash on all ham bands (at least up to 21 MHz), S6-S7 level, whether commercial power was present or not. I wrote to APC and they said their equipment met FCC regulations with regard to spurious emissions, and very k

I've heard similar things about APC UPS's. However I now have 5 of them sprinkled throughout the house and the modern versions (c last 3 yrs) are clean. I also have a cyberpower UPS that claims sine wave output that is clean. I needed the latter for one computer that would not accept the pseudo

Good Day All, Going through the inventory for the KSB2. RP1 & 2 are 8pin 101577083272p however I have only got one of these, the other 8 pin is L83C103. Have things changed or have I been sent an incorrect part? Regards Brendon VK8FQRP -- View this message in context: http://elecraft.365791.

Re: [Elecraft] KSB2 Resistor Packs

Brendon, I would wager that you purchased the KSB2 about 3 months ago. There was a short period of time when only 1 of those R-Paks was placed in the bag. That problem has been corrected by the kiting quality control. I spotted the problem when I found 2 kits with only one 2.7k R-Pak - one

Hello to all, Need some help. After finishing up on 80 cw last night I moved up to 20, hit the auto tuner for the beam and received HI CUR. And this only ocurred on 20 even with a Dummy Load attached. Msg seemed to go away once I reduced the wattage down around 60 watts. Hepl!!!

Looks for an RFI problem that only occurs on 20m. Or a grounding problem, maybe with a long leg like 5m or so. Nice resonant section there. matt W6NIA On Fri, 19 Aug 2011 00:31:53 -0400, you wrote: >Hello to all, > Need some help. After finishing up on 80 cw last night I moved up to 20, hit
