So this is almost too simple to share, but I like the results so much I thought I would post. (Forgive me if its been shared before) My car has a small AUXILLARY input jack which my Daughter used to always plug her I-Phone in to listen to music. I never used it.....but it still had the cord...

I also admire the professional contacts from Europe into the US. Unfortunately, I can assure you they don't run into the same treatment back. I scan / listen regularly and I am embarrased by what I hear coming in from around our lovely country by radio operators, (if that what you want to call...

Looking for a Cobra 146 GTL. Doesn't have to be a "Desk Queen" but NO hacks, clipped limiters, coil spreads, etc. Fully functional works for me. Include shipping in your price. I am in Mississippi, (just South of Memphis, TN). I'll pay via PayPal. Thanks

If thats the case, it'll be a good radio ! ! :thumbup:

I have a fairly large supply of capacitors available. If I were to put a fixed ceramic or variable cap, (2pf - 30pf range), on the board for influencing the frequency, where would you put it on the back of the board ?? In other words: Where does the fixed or variable cap go to influence...

399: I tried this and saw no improvement in the frequency obtainable with adjustment of L59. Thanks for the input.

FYI: The clarifier mod done to this radio is one of Robbs favorites: Lift one leg of D58 and power wire to voltage regulator. Do you think a more radical or different approach to the clarifier mod would help??? (as listed in this thread??)

Ceramic caps I assume ?? Across the non-grounded side pins ?? I tried some caps across these terminals but then the frequency shot up to 36.XXX Mhz.....so I removed them. Perhaps I was using the wrong values ????

What really gets me is that LSB and AM are perfect. The cores in the cans for LSB and AM are about "center", (up and down), when they hit the spec'd frequency. Its just the USB that is off. With the USB, the frequency gets to its lowest point, (toward the target), just as the core evens up...

Both of my 959's are great performers. Glad to hear you are having the same experience !

Grinder74: If and when I find a solution, I'll post it ASAP. This has been driving me NUTS ! Sounds like you are the opposite of mine.....I am moving the core UP and run out of change. You are bottoming out.......strange.....

Sonoma, Thanks for the input. I have replaced almost all of the small caps around L59 that appeared connected to the USB circuit.....including resistors in that circuit as well. Same result. I have a freq counter and scope so I will start at the crystal and work my way out to see where it...

Tucker442. Thanks for the offer ! I have replaced everything in the USB circuit with the exception of the L59 tuning can. Its the one closest to the front of the radio. You have PayPal ? I'll get you the payment for your trouble. Let me know......and THANKS

Everything checks out. Not sure where to head next. Where would I get a "Can" ? I tried a shorter and longer slug. The longer one helped.....but not enough. Any help appreciated.

Robb, Clarifier wasn't "cranked open". Just lifted D58. AM and LSB is perfect. Can you explain more ? THANKS ! !

I've got a Malaysian Cobra 148gtl I'm doing an alignment on. I have a problem with getting USB lined up. I've got the counter on TP1 and the radio on CH19 per Cobra's service manual. The frequency here should be 34.9865, but the lowest I can get it with the L59 can is 34.9906. Not...

Don't even think of getting a CB if it doesn't have SSB. SSB is so much more efficient, (and powerful), than AM. You can literally, (when conditions are right), talk all around the U.S. and many foreign countries, (Europe, Australia, the Caribbean, etc.). AM is like a "local talk" radio...

UPDATE So I know these new 148 GTL's catch a lot of flack for not performing as well as "vintage" 148's. I'm certainly NOT going to argue about the build quality and the fact that my vintage 148's just ROCK IT in performance when compared to the new ones. I can say that the two I inherited...

Got it. I kept looking at that schematic thinking "it has to be TR41", but I had just replaced it with a new one. Out of frustration I opened the little baggie and fished out another one and installed it and PRESTO, I have full transmit on AM. Moral of the story: Not all new components...

I had to fill out FCC Form 740 and declare one of the many choices available on the form for Customs to let it out of the cage. I believe I checked the box that said something related to "Importing Limited Quantities for evaluation and market suitability". The top has to be filled out...
