I appreciate the answer back. I revamped the switch and now all is working just fine, sold the unit yesterday with all the mods I installed including echo / talk back/ roger beep... excellent little radio, but, I hate tight spaces with add on boards LOL Thanks Again! Dodgem250com

Nope, you're not gonna find this stuff at Rat Shack, but, look here: ERF2030 w/ EN1230 Final Upgrade Kit For CB Radios - eBay (item 300263842231 end time Oct-10-08 18:29:00 PDT)

The way echo boards work is pretty simple, it's basically "daisy chaining" the echo board in-line with the audio input. The wire that was soldered to pin 2, needs to be wired to the audio pin and the wire from the audio pin needs to be wired to the other brown wire. basically, you are putting...

I would have to say that if you're going to use a linear, then just leave the radio as it is now and don't bother with the final upgrade. If you have a 2078, go with it, or simply upgrade to a 1969. going MosFet is really of no practical use if you're going to use a linear. Thanks, Dodgem

I am trying to find a replacement CB/PA switch for a Cobra 21 LTD ST. The radio works great, BUT, the switch is causing the unit to lose power, so, I'd love to find someone who might have a switch I can purchase. Thanks, Dodgem Dodgem250@somd.net

Sometimes it's just the oddest things that'll make you think. Dodgem

well... I have one here setting on the shelf here at the shop, it needs a new CB/PA switch. All I can say is that this unit is built cheaply like a Rat Shack unit. You can't very easily do any mods to this thing, I did put in variable talk back via the RF Gain control, but, don't think that...

"I've developed"... LMAO ! You mean, You read somewhere...

did you ever pursue the ERF2030 final upgrade?

LOL! Maybe you should stay away from the sites that have pretty girls on them, so you're not downloading files that popup and try to make you secretly think you're downloading something bad. I laughed when I realized what you were looking at. I think you have already been phished! LOL! Dodgem

Like he said, that's all great and good and I'm really glad that those guys are not having any issues with "their" trucks, BUT, I am having the issue, and I'm curious to know what the problem is myself. I've notice with my truck, that when I have the power mic gain down low, it's fine, when I...

Well, I don't know about the Phishing thing, but, I have not caught anything on my site yet? LOL! Thanks, Dodgem

I am perfectly aware of that. I have 5-6 of the display modules, 3 from parted wrecks and 2 brand new. I have replaced the OEM digit display with colored displays in those units. No, you can not use a standard digit display to change the color. I know all too well what's in these radios, they...

Yeap, I am trying to locate 3-4 mounting brackets for Cobra 21LTD/21X/77X etc. Or any mounting brackets with a 6" maximum width. If anyone can , I would appreciate it. Thanks, Dodgem Email: Dodgem250@somd.net

PLEASE DO NOT REPLACE ANYMORE PARTS IN THIS VEHICLE!!!!!!! Your ECU system is not designed to accept incoming RF at that level. This is a major issue with Dodge vehicles and their patented ECU systems, they are junk. I have seen so many cases where the RF is beating up Dodge systems, it's...

That's cute. My three 29's DK 1 watt and swing to 38 watts. It's just the DM kit! Thanks, Dodgem250.com

Old Dodge Pickup Trucks !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! That fancy computer just won't handle too much RF! Dodgem

Good Morning! The actual number off of the transformer is TF069 (Uniden) This is the number from a Cobra 21X transformer, not the Cobra 77X that I need it for, but, it does not matter, they are the same units. It's labeled T201. The advantage is that this is a pretty standard audio driver...

OK, so, what's the big deal about the channel digit display? I've replaced these things a thousand times, and a few units specific to this post, so... Do you want RED, BLUE, or GREEN? I got'em in all colors! I have to keep them in the parts drawer by the dozen, since everybody likes the color...

I contacted my long time pal at Cobra and he gave me some inside scoop on the latest, top secret, Tech. Repair Bulletins regarding the NW radios that everyone has been having the failing Night Watch light issue with. Basically, he gave me the repair information for the NW light failure issue...
