[Elecraft] KPA500 operating current values...

line voltage. Set to 120 vac...and at 500 watts output it shows right about 60 supply volts. Just wondering if maybe he has 4-1000 prejudice against solid state linears...:) - Chuck, KE9UW -- View this message in context: http://elecraft.365791.n2.nabble.com/KPA500-operating-current-values

Re: [Elecraft] Preferred upgrade sequence

The general assembly manual shows the KXVA3 installed well before the KPA3. You might try it that way. - Chuck, KE9UW -- View this message in context: http://elecraft.365791.n2.nabble.com/Preferred-upgrade-sequence-tp6736111p6737868.html Sent from the Elecraft mailing list archive

[Elecraft] Turning KPA500 with K3?

How to turn on KPA500 by command from K3...and maybe even the operate power? - Chuck, KE9UW -- View this message in context: http://elecraft.365791.n2.nabble.com/Turning-KPA500-with-K3-tp6734902p6734902.html Sent from the Elecraft mailing list archive at Nabble.com

Re: [Elecraft] Turning ON KPA500 with K3?

would turn off the KPA500...and turning off the K3 would turn on the KPA500...hmmm...or is that not a problem? - Chuck, KE9UW -- View this message in context: http://elecraft.365791.n2.nabble.com/Turning-ON-KPA500-with-K3-tp6734902p6735630.html Sent from the Elecraft mailing list archive

Re: [Elecraft] Turning ON KPA500 with K3?

wouldn't be that useful and couldn't be disabled with CONFIG (I guess). But I think I would like the option...an inline switch on my part would suffice for disabling the feature. Something to think about. Thanks for the info. - Chuck, KE9UW -- View this message in context: http://elecraft.365791

Re: [Elecraft] Turning ON KPA500 with K3?

Probably a simple circuit using the 12 volts on output would be the best approach to provide a neg pulse to the pin #8 to the KPA500 for both power on and power off. Also the pin #7 outputs a logic 5 volts when the K3 is turned on...another possibility. - Chuck, KE9UW -- View this message

All built. Everything I've tried works. Drives very easily compared to the Hercules II. ...still learning how to set PWR LEVEL per band... Chuck, KE9UW -- View this message in context: http://elecraft.365791.n2.nabble.com/KPA500-337-almost-built-tp6704216p6713696.html Sent from the Elecraft

Re: [Elecraft] KPA-500 HUM from PA and not from Speaker !!!

The hum seems to be the 50 Hertz power supplies? -- View this message in context: http://elecraft.365791.n2.nabble.com/KPA-500-HUM-from-PA-and-not-from-Speaker-tp6647675p6652787.html Sent from the Elecraft mailing list archive at Nabble.com.

Re: [Elecraft] KPA 500 Hum PC Speakers.

The hum is due to magnetic field in close proximity of the speaker...usually. Sometimes RF gets into them usually on the power cord. Ferrite fixes this, moving the speakers fixes the former. Chuck, KE9UW -- View this message in context: http://elecraft.365791.n2.nabble.com/Re-KPA-500-Hum-PC

Re: [Elecraft] KPA500 Serial 0194 Done!

Ha! I just put a Elecraft Noise Gen. kit together...missing one of the screws for the battery holder. BUT! All the other important parts were there, so I forgive them. I love the instructions and the way stuff just works when it's done. Chuck, KE9UW -- View this message in context: http

Re: [Elecraft] [KPA500] Serial Port Connections on KPA500

be connected to a transceiver (like a Kenwood with serial band data) for band data, etc. The KPA500 AUX (VGA type 15 pin connector) can be connected to the K3 for band data, etc. Thanks.

[Elecraft] KPA500 on 240 VAC in the USA?

Anybody using 240 VAC in the US? So it uses the same connector on the amp, but you have to fit a different plug to mate with your 240VAC/20A wall socket? Looks like this -! ...only without the dot. Or better still, any droop using the 120VAC option? About 10 amps I guess. Chuck, KE9UW -- View

Re: [Elecraft] KPA500 Serial 0194 Done!

I am really wanting to order this, started to twice, but the LED alignment kind of is holding me back. The screws I can manage. Any chance one of you can post a picture so I can see what or not the misalignment looks like? Thanks, Chuck KE9UW Tony Estep wrote: On Sun, Jul 24, 2011 at 12:40 PM
