Gents,
I'd greatly appreciate a comment or two regarding a TR-3 circuit
question. I'm fairly new to the group and have been following
recent threads with interest. Unfortunately, I’ve not found any
comments related to my question in the reflector or linked websites
so will be grateful for some feedback by members of the group.
I recently re-entered the hobby after a 30 year hiatus and picked
up a TR-3 with an unsalvageable open frame relay. John Kriner
supplied me with a Drake relay conversion kit but a problem
surfaced when I ended up with an extra choke not mentioned in the
Drake instruction sheet. The mystery choke is single wound, about
an inch long and the diameter of a pencil. I had another TR-3
sitting on the shelf for comparison, but, unfortunately, it already
had a kit installed and no mystery choke connected.
So I contacted John, explained the situation and got this reply: "
I am confused now too. There are different versions of the TR-3.
I don't believe the small choke is used. I think the 3 tier choke
should be un-soldered from the load cap terminal. Run it to the
center of the SO-239. And then connect the other side of the choke
to the load cap frame. Finally, run a wire from the load cap
terminal to terminal #4 of the relay board. I think this will do it."
To clarify things a bit, I’ve posted some pictures of it on the
Halo.net website (see link below). So before I wire it up, I
thought I'd run it by the group in the hope that someone can
identify this particular choke.. is it a Drake factory variation or
an owner modification? Thanks for any help you can give me..
