Absolutely...if you want to fix your radio, the best thing is to figure out "what caused the resistor to fail". Alot of guys will just replace the resistor with the same one or a higher watt resistor and consider it fixed. Thats not the best thing to do since you still don't know what caused the...

Not too much you can do but try to null the signal from that dirrection with a beam. Master Chief said it best.... your neighbour is putting out soo much power and swing he is actually pushing the bandwidth of his signal larger. The more power you use the more inefficent your signal is since...

Its also one of the most accurate ways to measure output power PEP. But I do agree with what a few guys have said already. You do need some basic tools but you can do alot with some cheap stuff that anyone can find. Like if he doesn't have a watt meter for instance... a 12 volt light bulb...

Try to figure out where the noise is coming in from... if its coming in the power wire, twist the wires together like a twisted pair as tight a you can (a drill works good). Then you can get some sort of torroid or I 've heard a titanium drill bit works ( I've never tried it though) and wrap the...

Thats pretty much what mine would do... I believe mine did about 8 watts carrier swing to 17... If I wanted I could turn that sucker down to under 1 watt swing to 17. I put in a homebrew compressor in mine and man that thing sounded good. They are a pretty decent radio and not bad on side...

Try to get the longest Firestick you can. As for the SWR..... thats a really decent match.. your firestick antenna is made out of thin wire and its does have alot of bandwidth. So for that reason it might be harder to tune that antenna flat accross the band.--- 1.5 on 40 and barely over 1. on...

If you can use a 6 foot Fire stick you should see some improvement. A 7 foot firestick actually will work really well, but its more than likly too long for your application. With fiberglass 5/8 waves the longer they are the better they work. So you might see a bit of a difference upgrading to a...

I should check it out..... I've been wondering how similar the new US test is to the "no code" test we have had up here in Canada for a couple of years now.

Check out the data sheets for both transistors. Thats a good place to begin.... easy to find on google or cb tricks

The thing with spreading coils is your never sure if its REAL power. Just like a capacitor a coil can hold a charge. When you tune or detune any inductance (COIL) there is a chance that the power you are seeing on the meter is not real power.... but reactance.... in other words the energy thats...

He could be running very low swing and all carrier. Or his meter could be a bit off. Then again if the pi input isn't tuned really "tight" you can get away with more drive in. I've ran alot higher drive into alot of amps and still do... Surprising how much some amps/transistors can take. I...

Re: pc 122xl/drift After I NPC'd the radio it ran alot cooler... but I then added a small heat sink behind the finals AND audio IC.. that really made the difference .. and I really tried to push that little radio hard, I would"nt care to push it that hard without the heat sinks, but that NPC...

Thats a new one I havent heard... I guess you mean R55 ( I think thats the one) or R54.... anyhow I know what you talking about.... replace the resistor with a cap-- cool I try to remember that one Thanks for the reply

Thats one thing that I don't care to do in any am radio...... jumper the anti spiking diode. its not worth it for the 1 watt gain (or so). I have done it in scap radios that I was playing around with.... but if I ever did that in a customers radio, the head tech at the shop would more than...

5 or 6 watts clean is pretty good... I've got around that number but I had to volt the predriver which I really don''t care to do.. unfortunatly I didn't have long to play with it. I did get in some more fets and I'm going to check out what I can get. To run the fet off of high volts low...

Good point.... it is a very HOT running radio.. after doing that NPC/volt mod to the radio it actually ran alot cooler... BUT regarless I did add a small heat sink on the side of the radio (audio ic/ reg) and at the back (finals) to deal with the heat. Heat sink helped... but then again I was...

One of my favorite radios... check out cb tricks.. I believe they posted Handy Andys mods for that chassis... he had some really goods stuff for that radio...definatly got some good swing/low carrier out of it. Its worth checking out... you will keep all the swing (15 to 20 watts) but be able...

So here is one that I have been pondering over in my mind... These mosfets (erf2030) by ekl that seem to becoming fairly popular latly have interested me since they came out a while back. This is my thoughts on the subject.... In most circumstances fets are used in an exact oposet way than how...

For the part of the mod where you adding a jumper, you need a connect6ion there because you are removing something. Like I think your refering to D8 (anti spiking diode), you completely remove the diode and then put a jumper across where the diode was. The mod will work fine, and your radio...
