ARE THESE "RADIOS" AB1 ?????

[Switch Kit]

Are these radios with the built in power packs such as the 2970s and the Cobra 200's and all the other radios with the attached amplifiers to them AB1 as they are ?

I've never been much for these kinds of radios over the years but I have come to lean more towards a cleaner type situation if at all possible. (More so concerning SSB then anything else)

I can see where these types of radios could and would be more then enough in the power department concerning SSB in general. So does this make these types of radios AB1 out of there boxes ? or is there more to it then that ?

Although Im not a fan of the Galaxy brand radios , I've heard some very clean 2970s (most RCIs) as well as the not so liked Cobra 200s sounding very top shelf on SSB .

my 22b which is essentially a 2950 gets good radio checks on ssb as far as audio goes with my echomaster mike. Thats a good question though switchkit. Im curious myself.

I personally would think they were Red , I would guess they would need a very good scope tested and whatever else a good tech would use to have them tuned for best performance.

I would just think those kinds of radios would be a easy way out for those that wanted to run clean performing radios with just under 200 watt pep to get there messages across without using some kind of amplifier on the side. CB AM/SSB anyway.

I don't see very many clean AB1 amps out there anymore , most are just class c splatter boxes that are at best good for AM only. Although they can still be delayed to work on SSB.

IM just saying , these radios I mentioned would be a good clean way out for a guy that was only looking for under 200 watts pep in a AB1 clean environment from given radio alone. IM personally all for it. Although IM not a fan of Galaxy radios of any kind , I do like the RCI 2970s modded for cb radio.

I personally don't care much for those radios ither , it's just that they have proved themselves over the years as being fairly reliable radios for what they are. Unfortunately , they do not make a cb radio with a 200 watt pep capability so a good AB1 filtered amp would be prefered by me. I could live with class C if AM was my only outlet , but SSB has turned out to be very satisfing over the years so it's a total plus to have the best of both worlds concerning a radio and or amplifier.

I think IM personally stuck in a old school type cb radio era. IM more then pleased with old school 148s/Grants for my operations or any other older AM style type radio for that side of the spectrum. IM a cb'er , and I have always been able to get all the channels I would need within the spectrum with those cb radios.

I don't need 400 channels nor have I felt the need for 10 meter radios in my line of the hobby. There are many ways to break the rules , I tend to use power but 10 meter operation is far and beyon the realm for me. Why would I need a radio that did more then 15 channels above and below the cb 11 meter spectrum ? Just to say I could ?

is there any cb or export radio (high powered or not) that advertises the bias class of its amps ? i havnt herd or seen any myself .

im not a fan of high powered radios myself . but there are those in situations where a seperate amp isnt allowed or isnt feasable .

al though i apresheat what you are sayin and am interested also i think that i should corect you on the rci2970 it is not a mod to the rakio for cb it comes from the factory that way and they are a very stout unit i ave on and if it dose have a problem the factry is very prompt to fix it for you it took them less than a week to fix mine and get it back to me

welcome to the forum madmax .

sorry , but , they dont come from the factory already set up for cb/11 meters . it would be against the law . they are fine radios though .

If you have one, open it up and measure the the voltage at the base. If its 0.6v, then you have an AB biased transistor. If it's less, you're getting into B bias until you don't have nearly enough to turn the transitor on, in which case you're at C bias.

hi booty monster not to fight about i but isnt 11m cb chanals i thought it was and isnt that am and my 2970i s a dx if that makes a difference but if im wrong well you learn somthing new every day

 

[BOOTY MONSTER]

no problem madmax . its a 10 AND 12 meter radio from the factory . yes cb and 11 meters are the same . most likely where ever or who ever you got it from had already converted it for you if its working on cb channels . cb had both am and ssb channels .

nope bought it brand new in febuary last year has a 2 year worranty onit i actuly fryed a transister in it and sent it to get fix last friday and had it back by thursday i had it peaked and tuned when i bout it and when i sent it in to get fixed they re alined it it was off .0015 so if you are going to have one moded make sure that the tek knows what he is doing thats y i blue the transister at least thats thats what ranger told me

The only extra channels i really use are 27.555 and 27.475 or if i'm trying to make a contact with a specific person. then i choose one within there. both of my base radios go basically wherever i want in the 11 meter band. and one of them is a regular cb that will do that.

Madmax, all 2950's and 2970's are Export radio's intended for ham use....wink wink. They all must be converted and tuned to function on 11m, this mod makes it illegal but thats the way it goes.
