the reason the htx-100 has a the narrower i.f. filter (3khz) is because it has no a.m. the 2510 has a 5khz filter because it has a.m. if you pass a 6khz wide a.m. signal through a 3khz filter, it is going to sound like crap. uniden could have used separate ssb and a.m. chains with filters in...

i'm glad you found that moleculo. i had been trying to find the link so i could post it here. but i had been running into dead ends as i couldn't remember where i had seen this page and couldn't find it again.

get it from 'don's cb'. he is the warranty center for connex and imports all their parts. that is where we get them. that board is not cheap though. i don't have don's number on me because i am at home, but you may be able to find it on the web. or just call my shop and someone there (i'll...

you do NOT need any type of license to legally repair 2 way land based radios of any type. this includes cb. the rule that you needed a commercial license was dropped in the early 90's.

6khz bandwidth for fm. man, no analog there, you could only use digital modulation like c4fm/4 level fsk. as for the manual, you may try ridge equipment they have a ton of manuals. i'd give them a call.

for those of you who may give a flying $%^, there is a formula to determine the bandwidth of an fm signal. it is called 'carson's rule'. you need to know the maximum audio frequency and the maximum deviation. the equation is; fm bandwidth = 2(maximum audio freq. + maximum deviation)...

am's bandwidth is 6khz. nnbfm (narrow narrow band fm) bandwidth is 11khz. this for a max. audio freq. of 3khz and max. deviation of +/-2.5khz wnbfm (wide narrow band fm) bandwidth is 16khz. this for a max. audio freq. of 3khz and max. deviation of +/-5khz. wbfm (wide band fm...

you got me there. that is true. :D :D

10-4. i didn't know you had already posted that. there is one thing...if i am seeing the results, you are seeing the results, freecell is seeing the results, and many others are seeing the results, then why aren't the guys who are doing these mods seeing the results?

thats just the positve peaks. for the ones who haven't noticed, look carefully at the negative peaks. there are barely any negative peaks. the radio is serverely undermodulated when it comes to negative peaks. it also actually makes the radio sound 'softer' or 'quieter'. you don't need test...

-ALL- meters have loss, or else every meter manufacture has found a way to defy the laws of physics. if there is no power being removed from the forward going radio wave, what is making the needle move??

the info for the galaxy 88 that cb tricks has will work. the only problem you'll have is calibrating the rx meter. that is -ass-uming you don't have a cablibrated rf generator. without that, there is no way you can properly set the s-meter.

now this is what forums like this is all about!!

sounds like everything is working up to the driver and stopping once it gets to the 'final'.

the reason they are doing this is to eliminate stress on the coax. many times the radio is pushed all the way to the back wall of a radio hole or to the windshield for a dash mount. the coax is then bent right up on the coax connector. having a pig tail eliminates this. companies like yaesu...

lets see here. no output and swr's off the chart. your 2879's are toast dude.

here is a piece of test equipment we all have. your ears. take another radio and place it close to the radio that you think has a blown 'final'. key the defective radio and talk, whistle, fart, whatever. if you can hear it on the 2nd radio, your chances of having a blown final is pretty...

hold on a second tiger remember when i said i couldn't confirm that connnex was doing this, but i could confirm another company was......

not, that i know of...but texas star, palomar, dave made, ect. all make 'add on' 'packs'.

if i was at liberty to say, i would have said so in my last post. but they are in the works. not being smart, i probably said more than i should have by saying that 4pill radios are in the work.
