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. 73, Mark K2QO FN03ra On Mon, Sep 6, 2010 at 5:23 PM, Mark Adams msadam...@gmail.com wrote: Robert, What DC voltage do you measure at the output pin of U6. 5.0V in TX Are you able to set

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, 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) Bob On Sun, Sep 5, 2010 at 5:48 PM, Don Wilhelm w3...@embarqmail.com wrote: Mark, I am out of help on that

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
