Dumb question, and please don't take it the wrong way. Where are you grounding your VOM for testing? If on the chassis of the radio you will get strange readings. Find the radio's actual ground plane connection and use it. (one radio I have has a wire soldered between to coil cans and I...

Glad you got your radio fixed. The Cobra 148 is a nice radio. BUT, I am having trouble finding anywhere in Jazzsinger's post where he tells you that you are full of SH*T. It appears "to me" that he was simply stating the proper way to align a SSB radio. Nothing wrong with that, that I can...

If you look at the Connex 3400 it has the third digit as well. It is used as a "band" indicator for the extra channels. That radio uses the left most digit for the band indicator. I'm guessing that they had a bunch of those and used them for that. The front of the radio looks almost exactly...

While store bought dipole antennas are fine. You can roll your own much cheaper and learn some things in the process. There are plenty of articles on the web (Google) on building a dipole antenna. You can even build your own version of the G5RV. You will be surprised at how much fun building a...

Hi, I have a used Ranger 2950(non-DX model) that is not working. Took it by a tech friend and he says the processor in it is bad. Due to the age of the radio, it's not worth buying the processor from Ranger. So, I'm looking for a 2950 that works well, but, may not look so hot. Mine looks...

Well, with that kind of budget and hopefully living somewhere that is antenna friendly, I would first look at installing the best HF antenna system that I could. A tower around 60-90 feet and a decent beam for 20-10 meters along with a good rotor and good quality coax. Then, I'd be sure there...

:confused1: I believe that I mentioned on the previous page that is what I ended up doing. And the radio works fine. (talk back is crappy, but, otherwise, it is a good radio) trucker

Sorry I did not see your post before now. The heatsink on the back is not as heavy as the one on my Connex 3300HP. I am looking for one similar to what I have seen on some of the Stryker radios. Those things are huge compared to the one on the 3400HP. 1/4 inch thick on the back plate and the...

Do a Google search on the model number from the board in your radio. You should find several places for the schematic. Or you could try : trucker

The Ranger 2950 mic is a 6 pin mic and the 2510 mic is a 5 pin mic. Won't switch out. I had the same problem and thought of that one too until I actually looked. Got a great deal here on a used 2950 mic. Have seen them listed new on a couple of websites(don't recall which ones, but, Google will...

With the proper mods both the 2950DX & 2970DX will do 11 meters just fine. trucker

Yeah.......right!!! Been trucking for 40 years and have NEVER had an export radio taken from me at any weigh station. Had one stolen once while in a truckstop in California once!!! But, the weigh station guys are not interested in CB radios, export or not. trucker :pop:

Thanks! I have been keeping a close watch for heating on the case. So far, it has run cool to the touch. (well, slightly warm, but, MUCH cooler than it did when it went crazy) I key it up and adjust the power setting to about 1 watt (I know the on-board meter is not that accurate, but, close...

Final update, the 3400HP is alive and working well. FINALLY !! How long it will last, is anyone's guess. The bad voltage regulator nailed several other parts, including one of the finals, (had both replaced as I feel it's better to have a fresh, matched set) and the trimmer, and three other...

If you get the IC 7000, you can use a Screwdriver antenna for HF and a dual band (VHF/UHF) mobile antenna. The 7000 has separate connections for HF/ and VHF/UHF, no duplexer needed. If size is an issue for mobile HF, the best bang for the buck in screwdriver antennas where you cannot or do not...

Maybe at the very bottom of the solar minimum,but, as already said, it's very unlikely to happen on 11 meters. And you would need LOTS of power and high gain antenna arrays. (like those in the post above.......but MUCH larger) Get a Amateur radio license (tech is all you need for VHF-UHF) and...

Well, an antenna tuner is a good thing to have if you are limited to only one dipole antenna. But, a good SWR meter and/or Antenna Analyzer would be better. That way, you can put up resonate dipole antennas (like a fan dipole for several bands) without the need of an antenna tuner. A fan dipole...

That's called feedback. Turn down the Talkback and you should be fine. As for the other problem, it could be that the super tune is over driving the finals. That can cause a whole host of problems. It will make your audio on the receiving end sound distorted. Also, you might have the mike gain...

No doubt on that one!! My old (4+ year old) Connex 3300HP is still going strong!! I broke down and took it by the last shop that looked at it and he said he didn't remember working on it, but, believed me if I said he had. He said he would not charge me labor , just for parts to fix it. He...

Well, the voltage regulator does have markings on it, but, I cannot see what it is in spite of what angle I try using my lighted magnifying glass. And also, with the radio connected to an outside antenna, no reception at all. I carried it out to my pickup and the same results. I just might take...
