[Elecraft] K2 #4520 up and running...

[HB9DUT]

Hi,

yes, K2 #4520 is up und running :-)
After i have changed the two transistors Q9 & Q10 the internal frequency 
counter has no problem anymore.
It is really a pleasure to work with the K2.

But i have one small problem. On 17m and 15m my K2 has only very low output.
All other Bands are ok. Receiving is ok, only the output is low.

All measurements are done with an Wavetek SI 4031 Stabilock and should 
be ok.
Voltage is 13.8V

Frequency      Offset        Pout       Current
  3.75 Mhz     10 Hz       14.9W    3.18 A
  7.10 MHz      7 Hz       14.9W    3.18 A
10.10 MHz      8 Hz       13.3W    3.08 A
14.10 MHz    13 Hz       14.0W    2.80 A
18.10 MHz      2 Hz       0.29W    0.75 A
21.10 MHz    10 Hz       0.32W    0.72 A
24.90 MHz    20 Hz       13.9 W   2.80 A
28.20 MHz    11 Hz       10.6 W   2.61 A            

I think the problem is not T1 or T2 because the output power on 12m and 
10m are ok.
Maybe i have a problem with L10 & L11 or C32 & C32?
