speech compression on ssb

959 checks out OK!

did u ever get your radio back from DTB yet? just curious about your results.
I got my 959 back today after it being tuned and aligned along with some mods at DTB's up in Pa. The first thing I did was pull the covers off and inspect his workmanship. He did a pretty good job.
The 959 checks out ok. I talked to another cb'er close by on am and it sounds good to him. I just made my first ssb dx contact on 38 LSB(shocked in a good way) It's got plenty of modulation with the stock mic but I hooked up my RF Limited 2018 mic to it. I switched from the stock mic to the 2018 while the close by cb'er compared mics. He liked the 2018 and so do I. The RF Limited 2018 is close in comparison to the RF Limited cr 577 mic which performs like the 575 mic of old. I also had him put a red led(scuffed up to diffuse the light) at the back of the meter that glows when I transmit. The meter's white light stays on but turns a shade of red on tx. I am pleased with DTB's work. Maybe I'll send my Realistic TRC-428 Nine Scan CB and let him breath new life into it!(y)
 
lots of ssb talk on 27.385 - 27.555 (ch38-55)did you do the dx959 channel mod, its pretty simple only 2 wires to cut and put 2 switches inline with the 2 wires
 
channel mod?

It's got the Viagra blue dot 'B' board in it. I made a contact on 38lsb with some guy out in some cornfield. I don't think that is a state. <More audio>
 
CP-1

I finally bought a CP-1 of TopGunTechnologies off of Ebay. According to their list of radios that the CP-1 can be installed in,I'm limited to my 959 unless somebody knows something I don't.

The instructions say to remove resistors R176&R186 beside the mic preamp IC and install the CP-1 at pins 1&2 of the IC. The CP-1 contains resistors that alter the way the mic preamp tailors the sound and us supposed to add speech compression on AM&SSB. CBRadioMagazine says it didn't make much of a difference to him when he installed one on his radio. I know that DTB Radio tuned mine with a certain amount of compression. I wonder if this will destroy what he did or accentuate and enhance the audio. I want speech compression though.

Be sure to read the comment section on the second video as CBRadioMagazine didn't do a follow up of this install. :pop:

Just got the CP-1 in. It has a little envelop stapled to it with a resistor inside. Check out what it says on the pic. That's news to me.

    Hello I have a old school 2950 receives great on all modes and transmits great on AM but no transmit on SSB. Does anyone have any idea?
