Yes Good Info!!:thumbup:

Oh Boy CB vs Ham agian. Wow why is there so much friction between you guys anyway??? No realy dont tell me we would have to start another tread. I agree with the post that said it is a worthwhile mod when done corectly. Distortion is minimal if noticeable. I see some distorion on the...

I have done this mod before for tests and it did not look like that. That isnt even modulated correctly at all. The NPC mod is to compress the negative peak so it dosnt go past 100% modulaton. I am not knocking this mod or condoning it I am just saying that that does not look right at all...

voicemax speech processor I have installed the voicemax speech processor in a stock cobra 25 and compared to a stock cobra 25 out of the box. It brings the audio up and makes thing more understandable. I havent bypased any of the internal amp stages but that sound like a good thing to try. I...

HAPPY WATTS?? OK this discussion on peak watts and RMS watts is getting old. Peak watts or PEP watts are what they are. RMS watts are what they are. Dont get them mixed up. Just like peak and RMS voltage readings they are what they are in there on catagory. So that being said when you read...

I just did the install of one of these the other night and i was getting pretty good numbers out of the radio. I didnt finish tuning everything yet and i am getting 8 watts dk and over 100 watts swing on my bird meter with a pep kit installed. My dosy meter only shows about 70 watts butt it is...

I was reading on this particular model and i guess it was and option that this one could have and was only istalled if ordered that way. I thought the info would be in the manual as well. I will post my results. If i have any other questions i will get back to you. thanks guys, MIKE...

I have a Yaesu FT-101E here on the bench and i need directions on how to install the speach processor option. I have the board here and all the wiring is ready to go i just need ot hook this board up. I have a munual on order but i am not sure if it has the info in it. If anyone has one with...

As far as jumping D8 goes it is not worth messing with like you said. With it being jumped it can wipe out the audio section of you rig leaving you with bigger problems. You can get plenty of power without doing the jump. As far as heat goes with one single final there should be enough...

The EKL mod is ok but it needs some help to get the full potential of the mosfet. With the cobra 29's I use the IRF520N mosfet instead of the ekl2030. They are Cheaper and work better as far as i am concerned. Since you are a tech guy a assume you have a ossillicsope. This comes in handy to...

You say it is off on all channels?? They have individual crystalls for each channel. I would make sure it is not just a couple chanels or may just need to clean your selector switch good with conatact cleaner and work the dial. give that a shot and let me know. MIKE D

I have installed a couple of these and you have to put rf sheilding around them and completely enclose them inside. i also use rg178 to tie them into the radio. on top of that you have to set you deadkey and swing right to get them to work right. but that would be the same for any amp. the...

I have a galaxy sirius radio that has no tx or rx. it will power up but no tx or rx. Cant seem to find any info on this radio. would like to see if there is a service manual for this radio. throw me a fricken bone man!!! :drool: ha ha thanks, MIKE

i am seeking the same info. I have one here that has no transmitt or receive. :(

Sounds like a bad audio chip. If you have deadkey and no audio or modulation that is probably what it is. MIKE

thank you for some reason i didnt see those schematics there. thanks again, MIKE

looking to see if anyone has any info on a dual mosfet mod for the 949 or 966ranger. I am looking for something other than the ekl version no luck with that one. MIKE

I agree that cutting limiters is bad. If you have a peak meter like a bird 43p you will see clipping your limiter does not get you more pep power. it will increase your avg power. this is because your avg power looks higher to your meter because you have a square wave instead of a sinewave...

I dont have a manual for a midland 79-893 and i am missing a few parts in the limiter circuit. it is on a board seperate from the main board. I am missing R606 R607 R608 R615 D601 D602. PLEASE HELP DONT WANT TO WAIST MONEY ON AN OLD RADIO I WILL NOT SEE TO MUCH OF IN MY SHOP. thanks, Mike

Well the higher the bias voltage is the higher your deadkey but you should not go any farther than 3.0 volts if you do it runs too hot. and we know what happens next. mine runs around 5 watts deadkey and swings to 16 rms dont know what the pep is waiting on my bird 43p to show up. i am...
