Gang,
Per Don's suggestion, I have forwarded all info to E-Support. One more thing
for here. I have summarized my Troubleshooting voltages.
The following numbers that are not consistent with the charts.
RF PWR Module, U7, Pin 3, 2.5V in TX vs the stated 3.5-4.5
TP1, 3.6V in Rx and 3.5 in Tx vs
Robert,
What DC voltage do you measure at the output pin of U6.
5.0V in TX
Are you able to set the bias current of U7 with R39 as stated in the
manual?
Yes, no problem
Does the receive side work?
Yes, I think. When I turn on the Elecraft N-Gen the noise goes a lot.
Bob
On Mon,
Robert,
One more thing on the last tests. I WAS able to peak up FL1 and C1 on RX
with the N-Gen.

Hi Gang,
Just finished my XV432 expecting to use it next weekend in the ARRL VHF in
my rover setup. Murphy has hit and maybe someone can give me a hand.
My setup is a K2/XV60/IO module running xverter duty with an XV222 using the
split IF, Elecraft control cable, etc. I've used this for a few
Mark,
I am going to guess that you are plagued with the gremlin of 432 MHz
energy getting back to the K60XV and interfering with its power
measurement mechanism.
Plug the XV432 for high power input and drive it from the BNC on the K2
until you get it aligned.
If all goes well when connected
Don,
I rearranged the XV432 to be driven at 5W with my FT817 (my uW IF radio).
Now, all the tests up to the one originally in question, were fine. I still
have 0 Volts at TP5.
What is new: When I rotate R22 CW while feeding 5W from the 817, at about
25% rotation of R22, the overload LEDs on the
Mark,
I am out of help on that one. If you have not already, it is time to
email support at elecraft dot com.

Mark,
Even though TP5 is zero, do you measure power output power with an external
meter? What do you see at TP6 (marked TP5 on the schematic. TP6 is at the
input of the gain block)

Hi all,
I have put together an XV432 transverter and it went together very well.
But I have a problem on alignment, so can somebody assist please.
Aligning the local oscillator, the instructions are to peak L3,L4,L5 for
maximum, for a peak voltage which should be between1.5 and 3volts,
nominally
