After posting about my problem with not getting the dialled up power output in DATA A mode, it occurred to me that perhaps it might be a good idea to run the Low-Power (5W) Wattmeter Calibration. When I assembled my K3 I never had to touch this adjustment because it produced 5W as accurate as I could measure it right out of the box.
Well, now I can't seem to get this to work. I tuned to 20m (14.071 fwiw), put the ATU out of circuit and connected my dummy load power meter to ANT1, which is selected. I set PWR=5.0. In the CONFIG menu I located the WMTR LP menu entry, which has the value 100. When I press TUNE the power meter reads 3W, which perhaps not coincidentally is the power level I set for tuning using the TUN PWR menu entry. When I press TUNE the SWR is displayed not the value of WMTR LP, and rotating the VFO A knob seems to have no effect on the output power anyway. I don't think there is anything wrong with the power meter calibration as PWR=5.0 produces 5W on CW and FM, but how exactly is the low power wattmeter calibration supposed to work? ----- Julian, G4ILO K3 s/n: 222 K2 s/n: 392 G4ILO's Shack: www.g4ilo.com Zerobeat Ham Forums: www.zerobeat.net/smf -- View this message in context: http://www.nabble.com/K3-FIRMWARE-UPDATE%3A---MCU-1.87%2C-DSP-1.69---%28Finally%21%29-tp17041394p17052554.html Sent from the Elecraft mailing list archive at Nabble.com. _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
