I've seen consistently that the 6M TUNE power on my K3S, s/n 10163
defaults to 16 watts. I have set the TUNE power at 20 watts and it
performs correctly on all bands except 6M. I've completed the TX Power
Calibration with the K3 Utility. All looks good there. I have PWR
Per Band set such that the KPA500 is driven correctly from the K3S. The
TUN PWR value as set in the CONFIG menu is 020 for 6M. But when TUNE
is pressed the VFO B display is 16 watts and the measured output is 16
watts. On other bands, when TUNE is pressed the VFO B display is 20
watts and the measured power is 20 watts +/- 1 watt. Also when the
PWR is set to 100 watts, the 6M measured output power is 100 watts +/-
10% This is measured using a known good 50 ohm dummy load and two
different power meters to confirm the results.
MCU is 5.66, FPF 1.26, DSP1 is 2.88. I think these are current.
Not a big deal in any way but just curious as to why?
Any ideas?
