Timothy (and TR),
My board has etched in copper "Bitx40v3 (C) HFSIGS.COM, 2016"
I doubt that PC board has been updated since then, if so it wasn't mentioned in the forum.
D15,D16 have a little diode symbol in the silk directly under the component.
That might be what you see in the photo and figured was a component marking.
If he's a hired gun, he probably gets all the dog boards that other folks give up on.
Not surprising he would run into the occasional head scratcher.
On my Bitx40, there was some sort of short under C107.
Must admit, that took me awhile to figure it out.
Removed the cap, it ohm'ed out fine, didn't see anything?wrong with the board.
Cleaned everything with alcohol, put it back, and all was well.
Perhaps a solder whisker shifted over a few microns in position during shipment,
or some solder flux picked up moisture?
But these do get checked out at HFSigs before shipping.
Would be interesting to take good random poll of forum members, see how many?
had trouble with the boards as received.
We hear tens of people with trouble in the forum, but there are thousands of boards out there.
> I get the feeling though that I was the only one who gave half sensible answers to is queries a while back.? (many by PM).
I vaguely remember somebody talking about stuff not being right and buying all new crystals.
And I may have posted my best shot at an intelligent response,
though I've been pretty busy these last few months.
Seemed the wrong approach, but wasn't going to argue.
Lots of people think I take the wrong approach too.
