[ARC5] BC-221-J vs BC-221-T or what?

[Commtekman at aol.com]

You are correct, I just found my manual, it is TM  11-300, dated 20 July 
1944, I was
almost two years old!  My manual includes change  1 (C1) which is 19 pages 
long
and it is dated 25 February 1946. Someone also posted  a TM 11-300A and I 
don't
know what it contains. The C1 addendum is expanded to  include set AN.

TM 11-300 is the one that covers all models. I think mine was  originally 
in a canvas case but I have only a canvas carrying sling.

Hello,
I follow your forum and thought I would mention that I do  have a TM on 
BC-221 sets, not
sure which one it was written for, I could probably find  it if it would 
help someone. I have
two BC-221, I think one is in a canvas case, both are  in storage and I am 
going over
there tomorrow.

Somewhere I found a military TM that  covers all of the BC-221 meters. 
Noton BAMA and I can't find it. It may  help because at least it would tell you 
what differences are between  them.  I have a BC-221, a late one with 
factory power supply. I have  to look to see which version it is.  Its in a wooden 
case which makes  setting the crystal calibrator difficult since it drifts 
a little with  temperature and I don't want to drill a hole in the case. It 
is quite  accurate once warmed up.

I guess the time has  come for me to keep one of these in the shack. I have 
had literally  dozens of them go through my hands over the years. Now I 
have two here  and one of them is going to stay. But which one? The J model is 
in  lesser condition. The T model is almost like new. Both have AC supplies  
in them--the one in the T model might be a factory supply. The one in  the 
J model is almost certainly homebrew. Both have the spare tubes and  hex 
wrench where they ought to be. Both have the correct calibration  books. Both 
were made by Zenith. 


Is there any reason to  prefer one over the other except overall condition? 
I have not tested  them yet. But it does not seem like they would be hard 
to get running.  Is there an achilles heel in them that I should check?


Any suggestions welcome.
