I saw a post......somewhere on the net that you could change something inside the radio for a richer sound quality during transmission. I think it was just a resistor change to increase the band with of the radio to produce a sound closer to studio quality. Anyone else heard of something like this.

I vaguely remember something like that. I think it was a mod for a lot of radios including amateur radios not just the Cobra. A lot of jokers i have spoken to over here have said the easiest mod is a HEIL microphone. Some of them run at 4 to 500 bucks over here!!!! Depends on how much you want to spend on quality i suppose.
They are made in Illinois so would be heaps cheaper to you lot.

I would opt to add a quality mic than chop up the radio.

Move along. Nothing to see here.........

This is the info I have on it:

Replace R114 (27K) with a 10K
Replace C46 (.022uF) with a .2 monolithic

If you take your time and research what you find there are tons of mods for the Cobra 2000 on the net.
Actually the Cobra 2000 has a good rep for its audio quality as stock! May not like what you get modding it out.
I would play around with different mics first.

This mod works very well. After i did it to my 2000 a local thought i was talking on an old Collins transmitter, it sounds that good! It also seemed to bring the modulation up because i had my friend talk on it while i was listening from a few miles away and i could really tell a big difference before and after. I even had him to turn the mic gain back to 12 because with a D-104 just barley turned open it was a little to loud for my taste.The only thing i changed was the R114 and have not felt the need to change C46 although i may try it just to see if there is a change.
