Looks like a cops radio. Very authority looking.... All you need is an old cop car, a buzz haircut, and a fake police outfit and you can play cop!!!

I bet that radio is built like a sherman tank, looks like a neat old school radio. Don't forget back in the day everyone and their brother made a cb radio. Sears, Wards, JC Penny, Kraco, Sparkomatic, K40, Motorola, Teaberry, Royce just to name afew. Some look pretty funny.

If it is built by Motorola; then it IS built like a tank!
You can bet that the specs built in this radio are 'Top Shelf' too . . .

" ...... There is a feature on the radio that I have not seen on another CB; an IF gain. It also has the standard RF gain. Between these two features the back ground noise can be eliminated. The noise blanker is also variable. ...... "

I'd like to have it just because it says "Electroscan" on the front.

Looks like a cool radio!

I read that. Let me rephrase the question.

What is IF, and how does gaining some eliminate background noise?

I found this:
IF Amplifier Tutoral - Radio Terminology Bibliography - Electronics Hobby Circuits and Tutorials - IF Amplifier

Seems to me that it's almost like a variable "filter" if you will. Maybe someone more technically gifted can explain it better than the article.

I know that I often turn down my RF gain and turn the volume up and am able to receive stations that were stuck in the noise level with the RF gain wide open.

With a winning bid of $76.00 it is a keeper even if it needs a bit of work.

i was up to $65, the last bids came in very fast in the lst few seconds, 65 was pushing the limits for me though.
