  • To anyone looking to acquire commercial radio programming software: Please do not make requests for copies of radio programming software which is sold (or was sold) by the manufacturer for any monetary value. All requests will be deleted and a forum infraction issued. Making a request such as this is attempting to engage in software piracy and this forum cannot be involved or associated with this activity. The same goes for any private transaction via Private Message. Even if you attempt to engage in this activity in PM's we will still enforce the forum rules. Your PM's are not private and the administration has the right to read them if there's a hint to criminal activity. If you are having trouble legally obtaining software please state so. We do not want any hurt feelings when your vague post is mistaken for a free request. It is YOUR responsibility to properly word your request. To obtain Motorola software see the Sticky in the Motorola forum. The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). Please use Google or some other search engine to find a dealer that sells the software. Typically each series or individual radio requires its own software package. Often the Kenwood software is less than $100 so don't be a cheapskate; just purchase it. For M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola). This is a large and very visible forum. We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. Please respect this.

The Cobra 148GTL was the best CB ever made, but that was 43 years ago! Now what?

Has anyone made a radio that is all around great like the 148? I sure have not seen it if they do. All the ones I have seen are cheap junk in a pretty case with colored lights. Piss poor ears. Huge finals in a circuit so badly designed that it takes a crap in a few months. Knobs fall off. Case made of thin metal. I could go on but you get the picture. China could make a fantastic CB with more features in a bomb proof case, if they wanted to. Opinions?

Yep, CB radios hit their peak in the late 70s and it's been down hill ever since. ... The Japanese radios were high quality and well designed. ..... There is actually a huge demand for those vintage CBs so there are repair shops devoted to completely rebuilding them. ..... Ham radios and police and fire radios and scanners are junk today as well. ..... All are using cheap surface mount crap and they all lack the front end filtering radios had back in the 80s. ..... Today it's all about selling poorly made Chinese junk for huge profit and as long as the lemmings keep buying em, they will never get any better.

call_sign_null said: I'm not a CB guy and "best" is probably subjective, but the Uniden BearTracker 885 looks pretty f'n rad: BearTracker 885 Hybrid CB Radio/Digital Scanner I've never seen or used this radio and can't really comment on anything other than the idea of a digital scanner + CB seems pretty neat. I don't think there's any 30+ year old radios that came packed with as many features. Click to expand...

Uniden 980SSB is one of the better current legal CBS.  

XTS3000

As a previous owner of a CB repair shop for the last 20 year, I've seen the decline in the quality of almost all CB's during that time. The 148 used to be one of the best radios for transmit, but especially receive. Now they are pure junk. The RF final now used in the current Cobra 148 is a AF (audio frequency) transistor! Not a RF transistor. If you whistle or input a 1Khz tone into a current 148, the final will blow almost instantly. The receive is horrible in the 148 and all the Cobras and Unidens now, they used to have decent SINAD at -110dBM to -115dBM. Now days decent SINAD is around -100dBm! That's a horrible receiver! I've been out of the CB loop for the past few years, but before moving on to bigger and better things, the best CB for receive and transmit was the Galaxy 949 or Galaxy 959 by a long shot - both legal USA radios. Uniden and Cobra have been spending all the cost of their radios into making them look "pretty" with color LCD's and other non essential things, rather than making quality receivers/transmitters.  

From what I've seen over the years, most CB'ers were all about the bling! :roll:

Stryker makes good radios nowadays. As does President. The President Lincoln II is a good radio, as is the Stryker 955. Uniden 980 isn't bad either.  

I have a 148 new in the box...................

Analog Retentive

That radio is just different enough from the more familiar 148 that I'll second Adam's motion, and suggest Justin/Communications Experts. But then, I didn't ask how many radios like that you have modded before. If this is your first one, this radio is not a good "starter" for learning the ropes. The PLL chip mod for extra channels is similar enough to the 'straight' 148 radio, but I'm convinced that the PLL chip used in the "F" radio is more sensitive to stray ESD damage. This also makes it more sensitive to go "POOF" if your soldering-iron tip is not grounded, or if the radio isn't isolated from stray leakage currents. If you're already familiar with CMOS-chip handling precautions, no big deal. If you're not, the hazard of "poofing" the PLL chip is worth considering. Justin knows those ropes cold. I've read rumors that the 148F-GTL can't be moded for channels. Wrong. You just can't be sloppy about it. On the other hand, if you're intent upon learing how to mod a CB radio, I'd suggest starting with five-and ten-buck yard-sale specimens before climbing into this radio. I don't think Cobra sold all that many of this one before they dropped it. For that reason, there doesn't seem to be a lot of high-quality step-by-step info on it to be found. Modificationss for models that were sold in larger quantities will be covered on multiple "mod" sites. 73

The mods for a regular 148gtl will work on this one, which means there's a bunch you can do to it, but you really need the test equipment to do it right. I recently had the odd coincidence to have a nice Cobra 148GTL, a nice Uniden Grant XL, and a nice Cobra 148GTL-F on my bench all at the same time. While they're all basically the same, the F model is definately much more of a mess inside from the factory, so depending on your experience it can be a "fun" one to work on.

If you can carefully solder, a channel mod is easy. Opening and unlocking the clarifier is also. CBR does good CB type tunes. As far as modding it goes, I wouldn't. The radios value will drop like a rock as soon as the iron touches. Mod the hell outa a Grant XL or 148. Same radio, you can add a six digit counter, and still have a valuable F.

Are the 148F's in that high of demand that they're getting more $$ than a Grant XL?  

Yep. Not as common a radio. The only Grant XL I bought for over 100$, was a new one in '99. I've seen F's go for over 200$ on ebay.  

Yikes!!! the XL is a much better radio! That's pretty amazing that the F's are getting that kind of price!

Mod for Cobra 148 Modifying the Cobra 138XLR is straight-forward and fairly simple if you have relatively steady hand and a low-powered soldering iron with a tip that has been ground to a small point. It is easy to unlock the units 858 Phase lock loop chip and to modify the clarifier to slide 1 khz up and about 5 khz down. The Cobra 148GTL can be wide banded as well up to 28.045 (10 meter). The 148 GTL can also be adjusted by unlocking the 8719 PPL and also to allow the clarifier to be converted to a slider, again witha slide of about 1 khz up and a down slide of about 5 khz. If you need a graphical representation of either mod, let me know I will provide it in the form of an email attachment. 73's Joe [email protected]

  3. The Cobra 148GTL was the best CB ever made, but that was 43 years ago

    The 148 used to be one of the best radios for transmit, but especially receive. Now they are pure junk. The RF final now used in the current Cobra 148 is a AF (audio frequency) transistor! Not a RF transistor. If you whistle or input a 1Khz tone into a current 148, the final will blow almost instantly.
