xv50
Locked

Hello everyone. I just wanted to give an update and post a question. I spoke with don last week was working on a few xv transverters. After speaking with don I found the control cable from the K-3 was not fully seating in the plug due to screws on the plug were not in there proper place. Fixed that and everything started to work. But I was having some stability problems with the XV144 model transverter Don once again stated to check the attachment of the power module that it is grounded through the board where bolted to it. I also to some pics of the board. And for some reason when I looked at them I noticed all the flux I had not cleaned off the board. Never really noticed it much before even when looking at it through a large lighted magnifying glass. So I cleaned up the board. And the instructions have you putting a small washer between the board and the power module. So as he stated the is where the grounding is happening and a bad ground would affect the stability. I rep
laced the washers with ones slightly larger to give a little more contact area. I believe it was Don that told me Elecraft sells or did sell A power module that the mounting area is thicker so there is no washers required there used as a spacer. But now everything is good. When I turn it on cold I will get about 22 watts out with 20 indicated. When I leave it on for a hour or so and everything is up to temp. I get about 20 watts out with 20 still indicated. So every thing seems to be good on the XV144 model. The question I have is on the XV50 At first it did not work I found Q5 to not be biasing. So I replaced it. This kit was partially put together by my father in law who purchased it before he passed. Then about ten years later I decided to finish it. But any how when I went to replace Q5 it looked like two of the legs may have been solder bridged and shorted. Maybe it as not bad. But I was already unsoldering it and had a new one so I just went ahead and replaced it. Then it would turn on after that. Then in the alignment I was not getting voltage at TP5 with the radio keyed. Re soldered some joint I found that looked suspect and once again cleaned all the flux from the board. I had voltage at TP5 for a short time. Then it went away upon investigating I realized I did not have that coax selected at the coax switch to go to the dummy. So I guess I transmitted into an open ended coax. Probably SWR way to high. And I probably burned up the power module. Looking fr om the front of the Xverter on the third lead toward the rear I have 13 VDC. On the second one back I get 4.4 VDC when keying. But never get any worth while at the fourth one back. All I get there is about .011 when keyed. So IT looks like the power module is getting power and is being keyed but I am not getting anything out of it. Just hoping for someone to tell me if this is correct and maybe if I can get this part from Elecraft or not.

Joe,
Great that you now have the XV144 now stable. It would appear that the power module has gone "belly up". I don't know if Elecraft has any left (the XV50 was discontinued), but you can check. Also check at RF Parts to see if you can find one. As I recall, that power module was discontinued. 73, Don W3FPR On 7/18/2020 9:50 AM, Joseph McIntire wrote: > The question I have is on the XV50 At first it did not work I found Q5 to not be biasing.

Don I found one online same part number says 68-88 MHz, 30 watt, 12.5 V is that the correct one.

If the specs I gave is the correct one that is. I think it is correct due to the part numbers are the same. Just the 68-88 MHz through me off a little.
