Aptos, I have a problem: I have been working the RTTY contest this weekend and everything has been working smoothly. 700+ Qs in 13 hours. This morning after being on the air for about one hour and running a pileup the rig stopped keying and I got a ERR 12V msg. Here is the setup: K3/100 w/55w to Acom 1000, output 600w. Interface is microHAM mK II. Software N1MM Antenna is Steppir, swr below 1.2 on 15m and 20m.
I have tried a different power supply but no change...the voltage on both fluctuate between 13.9 and 13.3; the PA temps do not seem to matter as this happens when temps are as high as 40C or low as 25C. I tried with amp in and out of the line and with different software, N1MM then WinTest. When I have the ERR12V msg, the power defaults to 5w and 12w becomes max...the rig keys ok only after cycling the power off/on; then will key up to 12 w in cw and rtty. I have to cycle the power on/off to reset the msg then I can move the power up to 55w...as soon as I key the rig, the error comes back and power reduces to 5w and does not key anymore in cw nor rtty. Gentlemen/ladies, any suggestions? 73 Tom CX7TT P.S. No T-storms or adverse weather here... ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
