Sorry, misspoke -- it was not T501 I touched up, it was the Trifilar.

I also just touched up T501's joints. No real help.
Transmit diagnostics still show 0W, and 10-ish V (which I think is low). SWR bounces around between 1 and 5 but never constant.

Yeah, I'd noticed those were iffy, too. I touched them up. No real help, there. Same results when I powered back on and ran the diag.

The joint top right in your pic is not soldered well, and the one top left, 2 down, also looks suspicious.

Here is the area in question, zoomed in from my phone camera.?

OK, so: the jumper wire looks good. So far, most of my other joints also look good.
The BNC connector itself though, I get continuity between the four ground pins, and the fifth middle pin which I assume is the signal pin. I'm pretty sure I should not have continuity there!
There are no obvious bridges, so I may have to actually try to rework the whole part. I'm open to suggestions :-D
Meanwhile, I will keep looking for other areas of the board touchups might be needed!

I'm pretty sure I did add that jumper....but that doesn't mean it's right :-D I will check it!

I think Ian was asking about the jumper wire on the main PCB that has to be installed to get the RF signals in and out of the BNC connector.
It's described in the assembly manual on the same page as the 'Wind and install transformer T501' instructions.?
