What happens when you do it manually at this same power setting? Does the power continue to jitter around 5.0 to 5.2?
The calibration code samples the power shown in VFO B every 100 msec, for up to 20 samples, until the last four samples have the same value. If they don't settle to the same value, and if that value isn't between one digit of the target value, the utility reports failure. But the code sets the power to 5.0 watts before the calibration begins. I'll play with this a bit to see what happens here. Thank you!

I don't know why the pre-calibration power setting would affect the automatic calibration, because the power is set by the calibration routine to 5 or 50 watts or 1 milliwatt (on each band) before any transmission. 73 de Dick, K6KR -----Original Message----- From: Dave G4AON [mailto:elecr...@astromag.co.uk] Sent: Saturday, December 27, 2008 2:26 AM To: elecraft@mailman.qth.net Subject: Re: [Elecraft] K3: Automated Transmit Gain Calibration at 5 W, 50 W, and 1 mW Dick, nice utility. I've noticed an error can occur if the K3 is set to lowish power when you start the calibration run. I had power set to 5.6 Watts and the 5 Watt cal routine failed. Setting the power to 35 Watts allowed it all to run correctly. Apologies if this has already been noted. 73 and all the best for 2009 Dave, G4AON K3 #80 f/w 2.76 _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
