hi switchkit,
the mb8719 dual conversion chassis is my all time favorite too.
this mod is not something you would be interested in.
i imagine most mods to these you are not interested in.LOL
cb is different things to different people. some care more than others what the person on the other end hears. there is no right or wrong here, just different.
(i know you already know this)
the R114 mod is about frequency response, for example, if the radios frequency response in stock form is, say, 200hz-10,000hz; then this mod would make it wider, like, say, 70hz-20,000hz. (those numbers are by no means meant to be accurate, just for example)
no matter what mic you hook up to the radio, it will only pass the frequencies in between these limits.
this mod widens those limits, allowing better mics to do their job.
i can tell you this, my voice no longer sounds "tinny" at all with my D104 silver eagle. not that it sounded bad before, but D104's are not known for their bass response. mine sounds nice and full.
SK, i would never mind buying radio from you, because i would know it hasnt been hacked up.LOL
take it easy,
LC
BTW, that is my friend jon's site you linked to. he is also a fan of this mod.
