Sorry I can't explain it better. I guess it is a form of compression, dynamic range compression. Maybe sometime soon I'll do a test showing a demodulated signal and how it relates to an audio signal at the circuit input. Thanks so much again for posting that project.
For imitation chrome knobs, I soak them in a solution of Scrubbing Bubbles bathroom cleaner and 91% Isopropyl Alcohol for a few minutes, maybe longer depending how much crud is on them. While rinsing, I use a soft bristle toothbrush to remove any remaining dirt. Works awesome.
No modulation in this test. The input was simply a 1 kHz tone or voltage signal applied to the input of the circuit where a microphone would be plugged into. In the second part of the test, the blue trace is being limited from going beyond a certain point. It keeps the output signal at a more...
With all of this talk about speech processors, I decided to have a little fun. I hope these PDF's upload correctly. I thank Lil'Yeshua for posting the project.
I bought one about a year ago and I must say, I have to agree with 9C1Driver. Poor quality and not even close to being on frequency. Once I tuned it, it works ok. A little warble on sideband. I use it AM only in my vehicle.
I use a 45 watt 16th inch chisel tip along with silver-bearing solder. Between the larger surface area of that tip and how well that solder flows, I've never needed any more than 45 watts.
IF you still plan on doing this, you're going to need more than just a switch. Depending on the relay keying circuit, a capacitor or a capacitor in series with a resistor will have to be added to the base of the keying transistor, through your switch, then to ground. You might have to tinker...
I never use ch 19 for chit-chat. I know it seems strange in the cell phone era, but there are many truckers who still rely on ch19 for directions and road conditions. I would never want to interfere with someone trying to do their job.
I don't think an antenna would look silly at all on your car. I'd go with a small mag mount on the trunk. Not the best place for an antenna, but for your needs it will work fine.
Hey Doffo, I recently acquired a MJF-264 1.5kW dummy load that has served me well. I know some people had quality issues with this dummy load. For me, I have no complaints. Ive put up to 1kW into it many times and so far its resistance has remained the same. Whatever you end up buying, try to...
His great radio voice and pleasant disposition on top of that pro gear does indeed make him fun to listen to. He has his own web site that gives a quick run down of his station. Pretty cool.
Hey Psycho, sorry to hear of your misfortune. I still cant bring myself to buy anything radio related from Ebay. Too many screwdriver jockeys out there. It's a shame an A hole coward like that got under your skin. Hope you go easy on your Valium. Peace.
Holy crap! It's raining sideways here in Pgh PA. The wind is really howling for sure. I'm actually getting a little worried because as the ground becomes more saturated with water, the more likely trees will blow over. I cant imagine what the folks who live further east are going through. Hope...
There are many people who can help you here but to take full advantage, give as much information as you can like, what is the make, model and year of the cb?
After being away from cb since the late 70's, I've also decided to jump back in. Started to get that itch about a year ago. This is a great place to jump back in. Don't be afraid to ask questions. Hope you enjoy as much as I do.
