K2 - Lost 40m Tx after install of K60XV option

Hi all,

need some advice.   I have a K2, and it was working fine.   Then I put
together the K60XV option and installed it.   Messed something up as 40M
Tx went away.    The rig switches to Tx, but I do not see any power
coming out of the system.

Any suggestions on what I messed up :(

Thanks,

Neil, KN3ILZ

Neil,

Does 60 meters work, but not 40 meters?

The only things that could 40 meters to fail after installing the K60XV are:

1) C6 is not the correct 4.7 pF value - it will be marked either 4.7 or 479.

2) Relay K1 not working properly, check the orientation and soldering.
3) P2 and/or RF J15 not installed properly.

73,
Don W3FPR

Don,

I don't see 60M working either. I'll check these tomorrow after work.

Neil,
When you did initial setup of the K60XV, did you
set D19 to Yes?
Cheers,
Alan

Re: K2 - Lost 40m Tx after install of K60XV option

In reply to this post by Neil Zampella

Thanks to all who sent advice ... Don (as usual) steered me in the
right direction.

I need to replace the K1 relay as I accidentally touched it when
removing the RF Board C6 capacitor for the K60XV installation. Didn't
think much at the time, but definitely bit me in the tail here.
