Henry much appreciation for clearing this up, from what I've read I still had a small doubt that a vertical with radials stacked over a beam would'nt have any ill effects on take of angle and lobe strength, you know when you get a "that just does not seem right" moment but you can't quite...
Thanks for that info Marconi, myself and a friend are in the midst of reworking
our base's and i was contemplating using a maco 103 flat side with my 5/8 over top of it, as well as my friend who also has a 103 but wants to use his imax stacked over top.
I was not sure if they would cause...
It's all good Toll Free, i understand and agree with what you are saying and as for the dosey, well lets just say it is old and has been bounced around quite a bit being in my friends mobile.
The limiter is not cliped or bypassed and i dont plan on doing that anytime soon.
when i did on...
No offence Toll free but notice how i said take it with a grain of salt it is after all a dosey and not the most accurate of meter on the market, so before you insult someone please re read carefully,
yes i know that 100% modulation of a 2 watt carrier equals 8 watts.
With that said when...
The only good thing in this video is the music.
I shed a tear for the poor little 142 GTL, but you know Karma is a b...h, and
I hope he recieves every form of punishment and pain he cause to the little
radio, Including being grab from the mic chord and slamed into the fence:lol:
Mike on the air im getting very good reports, tested the out put with a dosey so take it with a grain of salt.
Barefoot dead key 2-2.3 watts swing to 18 watts pep at 90% modulation.
Amp inline on low deadk key 40 swing to 100
medium 80 swing to 150-160
high 100 swing to 250

Well after a hole lot of pm's trouble shooting and changing some parts my cobra 2000 GTL is back on the air.
I did the mod that was linked by loosecannon the steps i did were
2. Change R114 to a 10K, and C46 to a .2 monolithic, this will widen up the audio on AM.
5. R180 - Jumper it...
nice thanks Mike, i'm currently performing the mod that LC linked, that Moleculo re wrote.
almost done with it, just need to go back to the electronic store for another 2n6488 for the power supply, .2 mica because they did not have any monolythic's left in stock.
My hat is off to all the...
WOW:thumbup: that is a pretty neat rig Moleculo. I wish they would do soething like that with cb's I'd buy one just for the fact you can say " hey i put this thing together".
For the dual knobs did they not come with a little teflon washer, and if not what did you do differently from what...
Awesome LC, that will come in handy, I'm just making a parts list for tomorrow ( need to make a dummy load so i dont bother anyone).
Dummy Load Construction that is the one i will make it should be more than enough for what i will be using it for.
As for your write up is most of that info...
none taken at all Mike, I'm just trying to understand this radio a little more so i can avoid going to "coil spreader tech's" and looking over the schematic for this thing , almost seems like algebra. going to take my time on this and do alot more reading.
Xtra large Double double youre my...
lol mike, it is always better to have more than one suggestion than have no clues as to what to do it nay lead me around in circles but at least it is forcing me to understand this hobby better.
if i figure something out be sure i will let you know mike.
thanks LC i will give that a try, this evening i by passed vr10 and hooked it up to the tone control of the radio, as i dont use it at all.
I know what you mean about the dosey there pretty inacurate but at least it gives me a base line to see what is going on. I'm calling it a night as this...
Thanks LC the cobra meters shows 30% and my dosy shows 50%
even the pep is low, 2.5 dk with 4 watts pep. there was one guy on the cb tricks forum that tried a mod with some good result nothing to high on the pep side lower carrier and decent avg power,

Ok tony thanks, i did find an old thread with bits and pieces of a mod for a 2000 without removing the limiter, but the thread linking to that mod no longer exist's.

theres a link in that thread post from Moleculo but...
I am somewhat confused, i had to lower my carrier with VR10 for my 4x1446 ab box which was not a problem.
Carrier at 2.5 watts has maybe 4 watts pep of foward swing with 30% modulation..... though at stock factory settings it will key 5 watts and swing 10 pep with 100% modulation.
Now why...
My pleasure, like i said it confused me aswell when i looked up the info on my 2000, i did not know what sw com stood for or what it did.
worse case scenerio open your ranger mic up and look at the ptt switch, inside that switch are 2 little brass clips side by side that just slide over a...
