Re: [Elecraft] KP3A circuit ?

Andy,
yes indeed I had a closer look and it seems that the left pin on P68A is by 
factory. I compared pictures of the pa board at google and there it is the same 
depend on board revision.

Re: [Elecraft] KP3A circuit ?

[Erwin Witt - DK5EW]

I have found now the circuit at the elecraft ftp server.

Found out also that there is a brocken pin at the PA board at jumper at P68A 
male connector. This brocken pin still remains in the according female 
connector. So lots of problems.

[Elecraft] Power can be set only to 12W on 100W version

[Erwin Witt - DK5EW]

Hi all,

suddenly I can set the power of my K3/100W version with the power knob on
shortwave only to max 12W and on 6m only to 8W.

That all happened when I was operating on shortwave the K3 got's suddenly
very hot. Hope that the finals did not shot.
I checked the KPA3 setting it is on "nor".

Any help on that ?

[Elecraft] HI SIG

[Erwin Witt - DK5EW]

Hi all,

last evening I switched on my K3 and got direct "HI SIG" in the display. I
dsconnected all cables but still the same. K3 is not RXing anything anymore.

Strange thing is that the morning I was operating my K3 (serial # 5776) as
normal and switched off after. 4 days before I updated firmware to latest
one but had no problem last days when operating.

Any help on that ?
