I'm looking for an online source for a manual for a Douglas Microwave Company Wattmeter, TS-1285/URM-120. User or service manul will help.

Hi Harry,

I used to calibrate these units. Not much service manual to speak of
as the circuitry is fairly straight forward and adjustment is too.

Short of a copy of a manual, any questions I could answer?

Thanks Richard
I understand they can be used as an swr meter, reads forward and reverse. While looking around today, I found the Army version AN/URM-120 via Sierra also numbered 164B and called a Bi-Directional Power Meter. The manual is on BAMA I and downloaded it from there, There are other contractors also, one being Struthers. Thanks for the offer.

Hi Harry,

Take heart that you've got an instrument that is superior in every
respect to the common Bird.
