I love when someone with a properly turned, quality station comes in and drops the hammer on all those distorted and over modulated stations on channel 6. It reminds me of car stereo systems. People don't have a clue about crossover slope, subsonic filters, frequency response, SPL, ground...

It's possible you have too low of a dead key to calibrate it.

Here is the amp I ran in the late 90s built by a guy that went by Sonny just outside the Houston area. It was 2 2890s driving 4 2879s. Great preforming amp, but caused a lot of interference. A little different than the Dave Made designs. Sorry for the poor quality, I sold this amp back in 2002...

I know that sound that you're talking about and that is the sound of an amp being severely over driven and probably poorly tuned. People that run a 500 watt dead key on a 4 pill will sound like that. They probably also lack the amperage to properly drive their equipment. I don't think a lot of...

I know some of you here know more about this than me, but here is my take. With AM there are really two types of loudness. There is the loudness of the audio circuit in the radio and loudness of the signal. Most radios have around 70 to 80% modulation from the factory. The radio can be tuned...

I know the band is pretty dead right now, but when skip is in there the band can be very active. When I got into CB radio back in 1988 at the tender age of 11, CB radios were not that loud on the air. Most CBers on base stations used quality mics like Astatic and Turner. If you had 1000 watts...

I ended up fixing this problem better by extending the length of the coax after the amp. When I installed my MK3, the oscillation came back above channel 28 or so. Adding 6 feet to to the coax after the amp eliminated it through and through. It also lowered my reflect power. I sold the amp and...

Thanks for the correction on Timbuktu! :) I found a local 10 meter Hamnet last night, a good number of people checked in to it too! I normally don't get on at night due to my work schedule. Old Goat, get your ham license and expand your options. A lot of hams get on CB or 10 meters when...

The best skip is when it concentrated on a small area. I remember several months back talking to the same guys in the northeast daily for over a week. I was having 10+ minute conversations with them several times a day, they sounded like they were locals. I also had some long conversations with...

Do you have any experience with them or know anyone that has? BBI did a voltage test on them in one of his videos and they took over 20 volts. Inside they were the same as the hg2879, they out preformed the DEI 2879s. Of course this doesn't mean much as far as long term use, but says something...

CB should have been on VHF since it was intended for local communication. Locals at night could also talk to family and friends farther away during tropo. I've heard that UHF was on the table when they were choosing what band to have it on, but they ultimately chose 11 meters. I always thought 6...

Thanks for the reply. I know they probably will not be as durable as Toshiba's. Not looking for a debate on how hard a amp should be pushed. Just asking to compare to DEI's with reference to Toshiba's. I already stated the voltage, the drive will probably be 15 watts. I know a 2X8 competition...

Hi all, How have the RFT PP100 "power pill" transistors that Xforce and others have been using been holding up and how much less/more power do they put out vs the Toshiba 2879 and the DEI 2879s? Are they better than the DEI's? I'm asking because I have a 2x8 class C that someone fried and was...

I heard someone like that a few months ago. 30+ on the meter and bleeding up to 27.505. If that moron only knew how much better he would get out if he kept that power on 27.025 instead of splattering harmonics all over the frequency spectrum. Of course you need to know what a scope is for that...

CB feels like corporate offices, too many chiefs and not enough Indians. In this case too many CB shops and not enough operators. Maybe they are starting to off each other to stay in business! :)

It's pretty dead in the Houston area as I pointed out in another thread not long ago. Truckers have always been hit or miss. Some are cool and have a lot to say. Others just ignore you unless you're one of their buddies and of course some of just rude in general. Here we have a lot of Spanish...

Good luck, schematic's are hard to come by for this radio. If I'm not mistaken the board is marked where the receive circuitry is, if that helps. Sorry you got one that isn't working. You should really email Mike and see if there is anything he can do, assuming you got it from New Zealand.

I was having a lot of problems with picket fencing and oscillation. I put LMR 240 for my jumpers and mini 8 for my coax from my antenna. I also put a shorter jumper from the radio to the amp and made the coax to the antenna longer. No issues now, steady signal and 1.2 swr's with the box on or...

I'm learning that SWR's are only part of the story with antenna and coax problems. I've had 1.5 SWR's with the shield not making contact. What kind of antenna is it and how high is it? Do you have another radio that you can put in line to compare? Could it be that noise levels are just low where...

The filter is only for sideband, it does nothing on AM. On mine the receive was great out of the box. My problem with mine was the AM modulation was very low. I had to open the cover and turn the AM modulation up. When I barely turned it, it went to having a lot of audio to where I have to keep...
