[Elecraft] Re: New K3 Power output problem

[Fern Rivard]

Hi Barry:

    It looks like your radio will need calibration of the power settings which as NOT shown in the owners manual. You will need to get that info from Elecraft or someone else on this reflector that has that info hany. I had to do that with my K3 back in Feb of 08 as it did not have full spec output on all bands
    73 from Fern  VE7GZ with K3 #412

Subject: [Elecraft] New K3 Power output problem


I have just completed building K3 #1397. It includes the KPA3, KXV3, KBPF3
and four filters.

 

It went together very well and all is working fine so far except the power
output.

 

I have done the 50W calibration per band and that produces an output of 50W.
However a setting on the power control of 71W gives 100W out and 76W gives
an actual 120W out. From there the power controls gives an output of up to
and beyond 150W.

 

I have tried recalibrating and I have downloaded the latest but to no avail.
I have also emailed Elecraft but given it is the weekend I do not expect to
hear from them for a few days.

 

I wonder if anyone else has had this problem and if so how it was cured. Or
has anyone any suggestions. I think I might take out and reseat the KPA3 in
case it is a bad contact but I don't think it is that.
