[K3] 6M power setting anomaly

[Vic Rosenthal]

This is strange. Firmware 5.33. On 6 meters when the PWR control is
turned all the way up, the VFO B display only reads 106 watts. On all
other bands it is 110 watts.

I know that the actual maximum power output might vary per band, but
shouldn't the PWR control set the requested power to 110 watts on all bands?

Do others have the same result?

Same here, Vic. Pretty sure it has always been that way on 6
meters.

Hi Vic,

I have the K3S with 5.33 firmware and see what you see. I believe this is
normal. Page 9 of the manual (Transmitter - output power) implies 6 meters
will be lower power max, although 106 watts is never actually stated. Based
on the statements of a lower max setting for 6 meters in this specification,
it would be a reasonable assumption the max power setting would be something
lower than 10-160m. Also, when setting CONFIG:PWR SET NOR, 6 meters will
operate independent of the other HF bands. Supporting some difference on 6
meters.
I actually thought I saw a thread some time ago from Wayne or Eric
confirming the difference in MAX power sets on 6 meters compared to the rest
of the HF bands, but have not been able to find.

Thanks to all who answered. I guess I never noticed this before.
