Weren’t they also in some Browning Golden Eagle bases as well? As a sideline, the Regency Ranger in that ad was a cheaper radio in its day. So many of them can be found with the filter removed. I managed to get one and replace the filter as a restoration. I gave it to my Elmer as a thank you for his years of teaching me. He is thrilled.😊
That radio in the lower left corner looks like a Mark Sidewinder. 50 years ago, the overmodulated loudmouths negated any filtering you might have on your receiver. Today, the situation has not improved. 200%, asymmetrical modulation will just blow right through any filters you might have.
A few other radio manufacturers used a mechanical filter, but not a Collins one. Lafeyette was one. All the non Collins mechanical filters I have seen worked, but not as well as he Collins did. There were more but I can't think of them right now.
from the net: Rockwell Collins was a multinational corporation headquartered in Cedar Rapids, Iowa, that provided avionics and information technology systems and services to government agencies and aircraft manufacturers1. It was formed when the Collins Radio Company, facing financial difficulties, was purchased by Rockwell International in 1973. In 2001, the avionics division of Rockwell International was spun off to form the current Rockwell Collins, Inc, retaining its name. The company was founded as a radio company in Cedar Rapids, Iowa, in 1933.
Here is a good pic and article on them. There was a video I saw of someone taking them apart, as they were originally filled with black foam and after 60 years, often the black foam would turn into black rubbery goo and start interfering with the filter, but I can't find that video. The fix was to take the cover off and clean out the black goo: www.wa3key.com/filters.html
I love the History of CB Radio Channel thanks, Tram MD.

Yes, up to the Mark 3, which doesn't have a filter.
They were in Mark I's and only in early Mark II's. In the later Mark II's they stopped using them. Probably cost.
My first radio was a defect TENKO 46T. One of the Valve-tube was defect. Now it works for ever...
Those are very rare over here.
Great videos, Yuma Az
I have a Tram Titan II with the Collins filter.
all matter of the Titans have the Collins, all are great radios. Most like the looks of the II vs the IIA
Nice, show & tell.
Thx.
Thanks!
Seen the thumbs up drop from 5 to 2 ?! Mine brought it up to 3 . Never seen it drop right before my eyes. I have a Royal that survived the tram dr.

A good tube radio will negate most of that, but of course, not all.
In some RCI 2950 radio and some other RCI radio you mite see some with a Kenwood Filter in it only be a few radio only to some who wanted the filter

Can you do a video on the General sb 72 mine is still dead I would love to see you do one on it.😊
I plan to one day, but that is a very complicated tube radio. I doubt if a video would help you.
@tramdr Yer I know. I still love to see you do one of your reviews on it.
Infamous?
Collims makes radios still mainly for military and Aviation

I like to take one filter apart, but if they are that expensive, nah. 😎
They aren't that expensive anymore.
@tramdr
🤔 Do you have a broken one?
Sorry, no.
@tramdr
I can't see destroying a good one since that are on the endangered list. But, if you every get a broken one, I'll buy it off you.
