J-38 Question

OK... So Every one of them seems to have it but of all the pictures I've seen on all the QRZ profile pages no one seems to use it.. So

What is the eyelet on the front-left of the J-38 supposed to be used for?

Why is it there and what is it's intended purpose?

73s & Enjoy! N4IVE - David Gale


To thread wires through to secure them when the J-38 was used as part of a practice system (that is what the shorting bar is for as well, though they were used in Railroad telegraph systems as well).

I have my cable fed through the eyelet, and then secured with a very small zip tie.

The first week I had my station on the air (1961) with my J38, I removed that shorting lever !

I kept accidentally kept bumping it and sticking my transmitter on the air.

The first time I saw the plate on my 6AQ5 final (only) transmitter tube get red hot before I saw the shorting lever was closed.!

CW is Real Radio

If you have a burned out DMM, it can be opened up where there is gold traces on the board.

Scraped some off and grind it between the j-38 contacts.

I haven't actual tried this. Just a thought.

73, kt4nn


The contacts on my J-38 appear to be coin silver or the like.

One of the old "point files" cleans them up nicely.

You want a square contact.

Mine got roughed up over the years by cathode keying vacuum tube rigs.

Th eyelet on the base was for a cloth tie from the cord.

Actually, it was the outer cord cloth cover when the conductors were removed.
It provided tension relief for the two conductors in the cord.
    Proper name is "circuit closure switch" for wire line telegraphy.

It remained for some time.

When the pivot screw is adjusted properly and the pivot is not worn, it will move, but not too freely.

A piece of clear tape over the contact area can insulate it.

REM : Wow !?

Hi Bill, I am the proud owner of four new pistols, FNS-9, Springfield HD Mod 2, (both 9 mm), one 22 single action and one BB pistol along with a Mossberg Patriot 3006 along with a 22 rifle.

I have owned since 1955 and a BB pump that I inherited from my brother.

I bought a 36" Gun Safe and built a save room.

I am in the process of fixing up the house to get ready for a Zombie attack.

I bought a comm trailer from TARS because its real owner decided he only has a short time to live.

(he is 69 and I am only 75 now, so I still have 20 years to enjoy it!

The trailer has a couple of bunks a radio room and some solar cells so will be good for a park with a community bathroom.

Been too busy with carpentry to get on the air much, but I hope to change that soon.

Well done Durk, keep up the good work and have fun!
