Yes. The trick is to set the XVxADR config item to either Int. trnX for
internal 144 IF use or trnX for the external 28MHz transverter. Both can be
set to display the same or different RF dsiplay frequency. Setting Int.TrnX
always uses the 144 internal transverter. The choice of the value of X
I have run my XV144 and the internal k144XV side by side on the same and

Thanks for your questions and helping me work through this. The RF voltages
I'm seeing are (on 30 M) are:
PRE - .068
ATTN - .023
OSC - .014
MIX -.105
BUF - 1.37
TR1 -.62
BPF -.076
The DC voltages on page 46 were all within the ranges indicated.
The output power in tune
OK, I assumed that tweaking the trimmers on the filter board would just move
the power out small bits. such as if you have the power out set at P2.0, the
trimmers would tune between P1.7 and maybe P2.3. I want in and starting
adjusting them, and I get power out now in the right ranges, and
I found one, Thanks!

Are you transmitting into a dummy load, or into an antenna. If you are
transmitting into an antenna, I have to ask - what are the
