Thank List and Don x2 and Matt
You hit it right on.
Pressing Display & Tune bypassing the power reduction of the KAT2, did get
the power up to about 0.57mW from the 0.2. Replacing R6 with a 470 Ohm on
the KAT2 did the rest. Now low power controle seems to be ok and the first
on air test of the XV144 work great. Still a few things to do RF seems to
sneak in some where, maybe i was not good enough removing the paint. Then a
issue on the K2, that the freq on XV144 are 1,2 Khz off. Proberly the VCO
alignmant of K2 or maybe i just need to make an adjustment in the Menu setup
of the transverter.
The Transverter also seems to drift on TX for the first 5-10 min of use. I
had a VHF contester to provide me with report. So maybe an oven are needed.

alignment )
Michael,
The ATU automatically cuts the power when using tune. You can prevent
that by setting the ATU menu to CALS or CALP. Remember to set it back
to AUTO when you're done calibrating the xv144.

When i installed the kxv60 i did not have the atu installed. After a
broken diode every thing tested ok. atu was installed. And tested ok. I
did not recheck the kxv60. when pressing tune to tx while aligning power
on xv144 i saw that the power from k2 could only reach something like 0.2
mW. i mentioned it here and got some help. now i did an other test on
kxv60 having taken the lid of k2 every thing worked ok 1mW was send when
pressing tune. I put the k2 together and started the xv144 alignment. Now
the problem was back. I have now found that pressing tune with the atu
installed result in only 0.2 mW on the low power out.
removing the atu control cable from the control board the low power out are
now 1mW pressing tune. i do not have a power meter able to measure that
level, but i belive having the atu installed makes the low power output to
be about 1/5 using tune to tx. Seems that low power out are ok when keying
the k2 with the mic and with the atu installed. Only measurement i could
do was to to check the output from the transverter. I aligned the xv144
using the k2 with out the atu. so 1 mW displayed on the display giving 20W
on the xv144. Installing the atu in k2 pressing tune give 6w from the
xv144. Now keying with mic shouting the south european olaaa drive xv144
to 20w. any word on this please
thanks in advance
