Hello Marty,
You have obtained one of the RF/IF click boxes that was used by Drake
technicians to test and/or troubleshoot the Drake products. These were
designed and built in house for use on several product lines. If you go to the
Drake Museum of LA6OP and the late Jean-Marie Cherry you will find a
description of this unit that I wrote for their web-site.
http://www.dproducts.be/Drake_Museum/rf_&_if_test.htm
We had several dealers with service departments and we produced the RF/IF test
fixtures for each dealer that wanted to service Drake equipment on site. They
sent their service technician down for a weeks training and they were given the
test fixture upon completion of the training.
Let me know if you have additional questions after reading the article on the
click box.
73, Bill

Subject: Can You Identify this?
Bill,
I hope all is well with you. I recently bought this and would like to know how
it was used. Before I bought it and it arrived here I thought it had a built in
power supply (Maybe a clone of an AC-4) but apparently it was used with an
external supply for the rig under test. I see that it does have built in
supplies for the RF and IF signal generators. I also got three sheets of
schematics with it in an envelope with Amateur Electronic Service of London.
Ontario on it. I bought it from a Canadian ham with the last name of Shack.
Was this used mainly for repair or for new rig calibration?
I plan to share some pictures and what info you can give me with the Hams on
the Drake List. The rigs listed on it are the T4-X, TR-4, TR-44, TR-6, TC-2 and
TC-6. The schematics have a 1969 date on them with a Miamisburg address and
drawn by a "EDF"
Thanks!
Marty
