What is the big deal with having a power mic? For instance, I can't run a power mic to its full potential, because everytime I key up with a power mic I have to cut it back because I start to get feed back from all the modulation my radio puts out. So myself I don't run a power mic because my radio is like having a power mic, some people think I am so I let them think I have a power mic. I think power mics are for those mudducks who think they can talk to the world on 4 watts.

does it do it without the amp on maybe rf in it but i agree i dont use power mike just stock mike on cobra 29 is loud enough but some people like that sound of the power mikes

Depends on the Power Mic...IMO the Astatic Road Devil is a P.O.S....But I do like the RF Limited Extreme 2018's. They work real good with Cobra 29's...Since the 29's don't have a echo board, the 2018 does, and is a good match up with the 29...Plus, the 2018 also has a noise cancelling switch that helps not only cut out back ground noise, but also helps with squealing...

Once you figure out how you want a 2018 set, you'll never want to go back to using anything else...

I have no issues with running a 575 m6 in my little honda.. with a 2x6...and i have talked pretty far when only on 3watts...with a noizy built antenna. One suggestion."bonding"!

if you have a problem with running a power mic with the amp on then you have rf coming back at the radio .

i've heard that the Cobra's come out of the box talking loud,especially the 148GTL's which is one of the reasons i have two.i've gotten great reports on my transmission while using either of the 148GTl's and they are both stock outside of the channel mods.
so maybe the fact that the Cobra's come factory loud and proud is causing the issue.meaning that whatever part of the radio that controls the audio output,mix that with extra power and you're getting the squeal.i'd find out what area of the board it is and have it turned down,if you want to really run a power mic.
just my .02c's and i am in no way a radio tech,nor do i know shit about the technical side of CB's.just an opinion from general electronics experience and use.

a power mic was designed for "stock" radios with no audio mods ... performing Audio mods eliminate the reason for a power mic... if a radio is done right u should be able to run a noise canceling mic and still have alot louder than stock audio and not pick all the back ground noise.... personally i run a RK 56 on my 29 ... and anyone that has listen to me knows i do not lack audio

i find that even with a stock radio you cant run the power mic wide open and mic gain wide open
usually gotta turn 1 or the other down alttle

I use to run a d104 astatic on my Demco Satellite tube base station in the early days and a Turner plus 3 ; but lately I have just used the noise canceling mikes as in my area there is not much traffic to cut through . Power mikes bleed over if not used properly also and distort . I am searching for my turner in the basement but would lower the output and it sounds good . I would never put a power mike over half power . I was looking at the road devil and might get that . I run my hr2510 only with a stock mike .

this is really 100% true what skipshooter said, but can run power mics like the vintage ones are best, 575m6, 1104c, silver eagle, turner +3 & +2, shure 526t, but must know how to adjust your radio mic gain(also power mic volume) and use chokes and ground out radio, power supply and box or you will get RID OF those problems. Once you adjust all those items the power mics will sound great. But have to know your shit on the adjusting and choking the mic cord to stop rf from getting in.

Ive been using a 636L lately seems to work on all the "hot audio" radios i own... and the volume of audio seems to be plenty. Great at cutting out backround noise.. but you have to get up on that sucker.
If you want "IN YOUR FACE" audio..i like the D104M6 older mic. Its dirty ,tinny, picks up a crap load of backround noise.... sort-a- like just yelling into the mic.

If i run my 2950 with power mic it tends to squeal at around 8000 watts but i put 5 or 6 clamp on ferrites right where it enters the radio and its all good

I have 2 cobra power mics. All though i am not a huge fan, I have one on my everday driver. Took me a while to fiqure out to get it to adjusted right. It is on like 3 or4 out of 10 on the dial. If i turn it above 5 it squels real bad.

Most of the time when the radio itself has been modified for audio, a stock 636l or road king -56 is plenty alot of people overmodulate if not careful because if radio was moded for audio really a power mic is not needed. Also noticed on high power vehicles 5 pill or larger they tend to stick with non-amplified mics, i guess the power increases the audio enough. From what i noticed at the keydowns. Just my thoughts.

I run a 575 in my surburban with a couple of k .. but like doughboy i run ferrite cores to keep rf out... I also run a 636L on my mini mobile witha 2x6.. sometimes a d104m6 and the 575. The 636L seems to work with eveything i own so far.

Like Doughboy and D-MAX 2212 had said, I agree 100% with using Ferrite cores, even more than one, on Mic cord to reduce RF works very well. I even do on my Base Station to reduce RF and any noises.

Actually, you can talk to the world on 4 watts.

Personally, I've used power mics in the past because I am not a loud talker. Some people scream into the mic so obviously having a power mic wouldn't be very beneficial to that person. So it just depends on who it is.

I have the RF 2018 TURBO connected to a Cobra 29 LX, and I have got good reports from everyone I ever made contact with. I keep both the volume and echo delay at 2. It sounds very clean. I thought I was buying the Extreme, that has a few more features, but very happy with this one. It's a keeper. Some people don't like the power mics cuz some use a 9 volt battery. No big deal really, I just keep a pack of 2 in the glove box. I've had the same battery in the mic since Jan 2013, and it's still going strong.

Agree power mic's are a personal preference...I love my 29LX and 2018 combo, they work and sound great together...Agree 100% with JesseJames...I won't change my mic for anything else...World Wide DX on 4 watts is possible but only during peak sun spot cycles and optimal antenna systems with increased gains like a 3 element yagi or greater... Definitely not going to happen sitting in your car on the side of the road...haha...unless your this guy...
