AW: [Elecraft] Problems = Alignment Part III K2 #4993

[Renardy, Martin]

Hallo Tim,

I don't think that you do have problems with the power supply. How do you run the power test? Do you use
a dummy load with a SWR/ Powermeter?

Do you align the band filters for every band?

Regards

Martin

Betreff: [Elecraft] Problems = Alignment Part III K2 #4993


Well, everything went fairly well up to the part III alignment.  I was able to get slightly over 2 watts during the first few steps of the alignment. However during the next steps, I get higher current than I should, and the max out is about 5.5 watts even with the current cal set to 3.5 amps.

3 watts = 1.1 amp
4 watts = 1.8 amps
5 watts = 2.4 amps

I have checked and swapped power supplies, changed power cords, and set current cal to 3.5 amps, but the max output seems to be about 5.5 watts. I get "Hi Current" indication even with the current cal set to 3.5.

I would appreciate any insight, I have visually checked everything  of course and don't see any obvious problem.. I looked at the troubleshooting section , but it seems pretty generic, I'm hoping someone might have run into this problem before and could point me to the right area to check...Any ideas?

Thanks
Tim
