The main SSB crystal filter is twice as wide as it should be and also the receiver uses a single (lightly biased) NPN transistor for the first mixer.
These radios were hopelessly overrated and their only 'real' strong points were the build quality and the quality of the audio components.
However, it really is just derived from an AM CB radio design with SSB and CW/FM added as cheaply as possible. (hence the daftly wide SSB filter that is really an AM filter)
Yes i changed my business name to a more professional name there cobraman148 sounded like a cb handle. like i said before if anyone wants to ask one of my customers how happy they are with the radios i have built they can ask.
Very impressive,so what band coverage does it now do?
Solid built radio,just like the export version we have over here in the UK. I have a boxed version of the Cobra 148GTL DX,and still going strong after nearly 30 years.
That Cobra 148 GTL is unreal! My word you got yourself a good one for the collection. I owned two old versions and one new version. I simply like the 148! Take care, Bulldog over here in Maine, 73's.
You'll have to acquire a 12 Volt Power Supply with at least 5 Amps or more. Most power supplies are regulated at 13.8 V, you may buy one at your local Radio Shack or even some Surplus Stores. You also need a CB base antenna and an easy one that works good and it's easy to setup is a Antron 99 or an Imax 2000. Hope this helps...
For the more basic mod I use the front panel switches instead of drilling holes in the radio that de-values it. Also installing a small frequency counter on the top of the radio with velcro looks nice and works real well for SSB.

Hi VA, lovely old Cobra, i have a 148GTL myself, i think they're a nicer looking radio than the DX, mine is as new in the box, will never part with the old girl.

Nice channel display modification showing Alpha channels & minus numbers!
I still have a mint condition 148 GTL-DX (Mk 2) which I love to fire up when the skip is running.

@VA3JOR the Snake used to go in in blocks of 40 three x3 40 120.
My last Snake had three highs one mid and two lows and it put a hell of strain on the Snake on the triple high.

You can find the person who made the modification, all you have to do is go on Ebay and search for Cobra 148 GTL and find seller called cobraman148.
