[Elecraft] K3 variable power output
Many thanks to Mike, N5WNG, and Jeff, W7BRS, for comments. I'm measuring the output power on an external power meter and the internal power meter is pretty well spot on. I have a KAT3 and I've been doing the ATU TUNE (10W) before I key at 50W or whatever. I noticed that the PA TEMP was set quite high (27 deg C) so I turned it down to 22. I've just upgraded the firmware to 2.63 and it hasn't solved the problem! 73 Bob MM0RKT ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K3 variable power output
I'm running firmware 2.57 and I've recently noticed this... An odd effect with the output power: it builds up from 5W to the dialled in power over the course of about 5 QSOs after I change bands. If I stay in a band and increase the power from, say, 50 to 70 watts, the output immediately drops to around 5W and then increases to 70W in the next 5 or so QSOs. If I drop the power, the same thing happens. I originally thought it might have been heating up - or something - of the the new balun on my Windom antenna, but it does it with a dummy load as well. Any help would be appreciated. 73 Bob MM0RKT K2 #5339 K3 #1456 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

RE: [Elecraft] K3 variable power output
Don't know if you got a reply on this yet or not. But try doing the TX Gain calibration described in the manual again on ALL bands at exactly 5W and 50W. 73 Greg AB7R -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Bob Towers Sent: Monday, November 24, 2008 8:07 AM To: elecraft@mailman.qth.net Subject: [Elecraft] K3 variable power output I'm running firmware 2.57 and I've recently noticed this...
