Collins S-Line KWM-2 Enlarged Photos and Descriptions Left Right You just have to love this gear. They look like real radios and better yet, they set the standard of performance for many years. Heathkit heaped tons of flattery on the S-line by producing as close a copy as they could. However, it took the Drake C-line to reestablish the performance standard. The Jap junk didn't do it until rigs ...

Collins R-390 (1951 contract) This Collins manufactured R-390 is the only other piece of Collins gear I own besides the KWM-2A. When this receiver came to me it was missing all the small front panel knobs, the PTO was in pieces, a bank of the variable inductors had all the flexible tuning shaft thingies broken off, and the PTO shaft coupler was missing. After taking care of those problems, I ...

R-390A Audio Modifications by Chuck Rippel, WA4HHG In troubleshooting my 32V-3, a condition occurred which bears repeating as a warning to other owners of Vintage Equipment. However, I am not an electrician so check your local situation and codes before proceeding at your own risk. My 32V-3 was blowing HV power fuses due to an internal short. In the circuit, there is a 115V lamp HV indicator ...

The 51H-3... ...is to my knowledge the first remotely-tuned receiver made by Collins. Several previous Collins transmitters used Autotune units, but this was the first receiver to use one of the mechanical positioning units. The unit in the photo is actually a military R-105A/ARR-15, but is pretty much the same as the more rare commercial unit. Incidentally, the electrical difference between the ...

The 75A-4's can be plagued with problems associated with low gain and audio popping or distortion. The source of these problems have been pin pointed to those interstage coupling capacitors which couple the plate of one stage to the grid of another. In my trials to finish off the A-4 on which I have been toiling, I did a little research on the classic cap problem and identifiedthe trouble ...

Welcome to my Collins KWS-1& 75A4 Page Welcome to my Collins KWS-1 & 75A4 Page. I have included some pictures of my Collins KWS-1 and 75A4 station. I have owned this station for about a year after purchasing the receiver from a ham in California and the transmitter from a ham here in St. Paul. The transmitter is very (!) exciting to have in the shack, to operate, and make contacts with. I enjoy ...

Collins Stock Page Here is a piece of Collins Radio stock. It is an attractive piece of Collins history, valued only for its asthetic beauty. Just for fun, I used a scan editor to erase the ERNST & CO name, fill in the erased area to match the surrounding mottled colors, then put my name and call sign it. When printed out, it was difficult to tell from the original. The original has an ...
