not exactly true the fcc does allow user/field/front panel programming of radios. it just can not be easily done. the icom p25 radios are front panel programmable by the user/operator. u have to do a song and dance to get to this mode, but it can be done. the radio must also be...

a little more power hope ray does not mind me adding a little something we have been doing to all our 'from the factory' mosfet radios. steve has been adding a 25v 10,000uf cap (available at westgate labs) between the main supply rail that feeds the 2sb827 and the ground rail of these...

If they did, they were not on display when i was at their booth. at least i did not see any cb's at the maxon or midland booth for that matter. maybe i missed them, but then again i wasn't really looking for cb radios.

here is an idea.... how about some basic electronics tests?? i see all kinds of suggestions, but none that tell you how to track down the deffective component. like testing the base emitter voltages. the emitter should be about .5v-.6v below the base. if you have 3.5v at the base you...

that is correct for lower power levels. but once you hit the several hundred watt mark, the cheaper mini8's loss will increase and its characteristic impedance will wander around as it heats up. the lmr will have consistent loss up to and past this level. at the higher power levels, the lower...

240 is the same size as rg8mini (.24 inches) and 400 is the same size as rg8 (.4 inches). the shielding and loss is much better on the lmr products.

in all honesty, we have been doing some mods of our own to the connex 3300hp and have been seeing 70-75w pep at voice peaks. the 55w pep i posted earlier is for a stock peak and alignment.

the built in power supply has gone to crap, a common problem with this radio.

55w pep is the average we see.

we don't have to...the schematics tell the story

rci has never been able to duplicate the claimed problem. i myself have never been able to duplicate the problem with any of my test equipment.

that is exactly what this product does. this would eliminate the problem 'psycho' is seeing with his equipment. you can also take a basic antenna matcher (matchbox) and put it inline between the radio and amp and have the same results. it is transforming the input impedance of the amp to...

the amp is not displaying the same impedance as the antenna or dummy load you tested the radios into. in other words, the connex is most likely delivering less power to the amp than the 148 because of the impedances that the amp is 'showing' to the radios. and of course if the connex is...

bob..my post was not aimed at you or what you had said in any way. i was just adding some tech notes on the 'how and why' pertaining to the a.m. side of the house. and looking at it, it does actually support what you were saying.

the answer is still...'reduce your carrier'.

the link hamer gave is good but it is generalized and does not tell the whole story for rf. all a.m. only cb radios are class c. this is fine, and there is no distortion because they are using high level modulation. the flywheel effect completes the missing cycle with no distortion. radios...

that means you have negative modulation...also known as 'too much deadkey'. reduce the carrier level until the needle no longer 'swings' backwards.

a.m. is class c and ssb is class ab
