K60XV Low Power Issue

[k2qo]

Hi Gang,

Setting my XV222 and XV432 up to run with my K2/10 with I/O has been an
issue and I just found out why. With the K2 set for LP, split path, the
power out at the phono plug is not 1.0 mW as setup in the menu, but 0.2 mW.
The transverters work FB when set to single cable and HP, say 5W drive.

I figure that the K60XV has a problem. The manual says to check the parts in
the LP path. Without any RF voltage info to go with, I figure that just
replacing Q1, D1, and D2 will likely solve the problem. It's a shotgun
approach, but looks reasonable to me.

Comments?

I'm also on the fence. I really need a rig in the shack that'll do 100W on
6M and be a b/u on HF. I had a TS-690SAT and did not care for it much.
Choices are the XV50 and TE Systems 170W amp or an FT-450D or maybe an
FT-950. A K3 is not in the FY11 or FY12 budget. E-Skip season is almost
here!

  Mark,

Do you have the KAT2 installed in that K2?  And if so, did you change
the KAT2 R6 to 470 ohms as mentioned in the manual - the K60XV kit
includes the 470 ohm resistor.
