Problem wth new K1 Build

m0bmn
Hi All and all the best for Christmas

 

I Have just completed the build of my new K1 (Christmas present to myself)
but I have a problem,

I have a 4 band module that I now works fine in another K1 I have tried it
in so im sure that there is no problem with that

It passed all the tests fine on RX ,and with the 4 band module above fitted
no problem picking up sigs.

I carried on and added the Tx section and started doing the checks there,
all seemed fine until I got to the TX check stage.

I use a current limiting supply and set it to 500mA @ 13v

I noticed the rx current with the back light on was just under 70mA so
that’s about right.

When I go to TX by holding in WPM+ & WPM-

I found that the psu was drawing the 500ma and current limiting (even with
power request set to 0.1W)

I stopped the test at this stage, unplugged the filter board and re-checked
all the voltages in section 9 page 46 of the manual,

All seems bang on, I put it back into tune mode without the filter board and
noticed that Q6 was just warming up, current drain was around 200mA

Im not sure where to go from here anyone any ideas, it would be great to get
the K1 running in the next couple of days for the g-qrp clubs winter sports.

Hope someone can help

Paul
