First why would you remove the pot from the outside and put it inside? Why put what ever you made into a cardboard box? I know some idiots like to let the smoke out but this is a pun gone too far!
I would love it if someone developed a mod with capacitor changes that would get the 3DB down on the bottom end to 150hz and the 3db down top to 4500 to 4800Hz! It would be an audio beast satisfying 99.9% of people! The stock 300hz to 3000hz makes sense from an engineering stand point if...
Well I just got one for $207 so I pulled the trigger. I know I am a sucker too! LOL
To my way of thinking it is a poor mans Stryker 955 with 3X the feature set. If the AM audio is 85% or greater that of the Stryker 955 it is worth every penny!
Now I need to build a 4 or 6 transistor amp and...
So outside of power output I was woundering if anyone has done a head to head with the two radio's in terms of TX audio mostly but also all other parameters?
I am never going to purchase a Stryker 955 due to price point alone.
I am going to assume that the Stryker 955 has better AM audio and...
Guys if the Cobra 138XR has not been butchured their audio chain has a simple compression circuit in it as well. Not on par with the GE but it does have compression very mild. You can get them for far less and those are SSB as well. That is what Mike of Mikes Radio Repair told me at least a long...
You where probably hanging out with guys that worshiped at the alter of the Cobra 2000. To me those are just a Cobra 148 GTL, a freq. counter, cheap power supply and cheap alarm clock at a stupid markup then and now. Not that any of the above is bad just not as good as the GE!
Back when a...
I am a powerless victim! LOL
It is a predatory practice! It is no different than KGB honey trap in occupied Berlin! LOL
I ordered a QT-60. I do not need it at all! LOL....It was 20% off but it was not even a good bundle!
You want a 1 to 1.5 watt dead key in a bipolar powered CB radio and just let the radio swing with out anything like super swing or NPC. That is with a single final radio. So think Cobra bipolar not mosfet finaled 25, 29, 148 etc.......If you can not live with that you need to bypass the driver...
Thanks!! I was hoping to purchase a Pride DX300 but they always go for stupid money on Ebay!
I am glad I asked because Iw as going to go with 2500 volts. So I will go for the less is more route.
I was going to use your High Voltage and Low Voltage boards in a Pride amp but now I am thinking...
So I have a bunch of odd ball parts that have slowly found their way into my parts bin.
I think I have some place around 10-20 4X150A mostly Jan 7034 NOS in various questionable states. About half of them are still sealed in their Eimace or Jan Packaging NOS. The rest are still sealed int he...
They are under $5 each on the ebay. I have not used them but we are all familar with this family of parts in past products that where fairly expensive in the past. Add a voltage regulator if the radio you are installing it in does not 3V-5V internaly and you have a lot of performance for cheap!
My Grandpa gave me my first CB radio a 23 channel Pace 123 I think it was.
I love that man with all my heart and soul. I am not 1/100th of the man he was! My Grandfather and my Dad are truly hero's to me. Not perfect men but incredible men all the same!

MMM is doing a bunch of stuff to the audio and the rf.
MMM is using Compression, Downward Expansion, Asseymetry, EQ and a lot more audio power to rf power than is typical outside of broadcast radio. IN fact he might be exceeding that as well. He is using a lot of audio band width and rf...
Thank You very much.
I dig and dig and dig and it is so easy to get lost in the Naming COnvention of these Chinese made wonder radio! Plus the threads wonder around as well. You can easily read 23 threads and only get 2 posts that are useful and even then the names for models are hard to keep...
