bob85, before I comment on the series regulator shown, can you post up a schematic or picture of the transistor circuit this is driving so I can get a better feel on how its loaded? The series voltage regulator circuit used as a keying/bias circuit looks interesting but there may be some room...

Took all of my exams... :-)

I would be interested in seeing various schematics, models used, and calculations too. :-)

bob85, all FET's are non-linear when used for large stage gains. If you use multiple stages, you should get a pretty linear system. Use enhancement type MOSFET's since they are biased class "A" with no signal. Ken

I replaced my Vista operating system with XP Pro... Vista has incompatibility issues with older versions of software and extrernal hardware. 8)

Another benefit of a larger diameter antenna is that the BW is increased, or the "Q" is decreased, which is normally a good thing when trying to tune...

Not if the house has ground fault interupters installed, then nothing will work. The neutral and ground wire are both bonded togther back at the service entrance and provide 2 separate paths back to the panel. The neutral carries the normal/system current, and the ground should only carry...

Lords, the military considers anything greater than 30 volts as dangerous. When the body is depleted of electrolites, and covered in a heavy, salty sweat, the body resistance has been measured as low as 300 ohms. Feel free to ignore the voltage around you since you have a high body...

He is talking about an isolated, or floating system, and in an ideal system this would be true because there would not be a path for current to flow. However, since all AC electrical distribution systems are grounded for safety and reference purposes, there would definately be leakage...

I know the USCG uses HF in their aircraft and aboard ships and aboard some small boats. I was stationed at two large area communications stations and HF is still the preferred long range communications method for aircraft. Both data and voice can be encrypted if needed... The NTIA regulates...

Yep... I've even owned a few... :lol:

I'm partial to pencil type soldering irons that allow me to change the heating elements and/or tip size for the job I'm performing. For connectors I normally use a 100W element with a 1/2 wide tip which means it has a large thermal mass and will heat a large area very quickly. If I'm going to...

Nice... My '98 color was very close to that - Chille Pepper Red. If I didn't have so many $'s tied up in my '03 Rubicon (TJ), I would consider a JK. :)

If you post up the high powers, I want to see pictures and specifications... :P

The open end of 18' of coax that has a velocity factor of 0.66 will create a low impedance standing wave (approximately 50 Ohms) to be seen back at the CB. If the 1/4 wave antenna is tuned correctly, it will also be at its low impedance point at the feedpoint. So, theoretically the...

Noise can also come from daisy chained grounds, or be coupled from other high current draws. I would make all of the grounds connect to a single point and also add a bulk capacitor or two across the power lines right at the load end. You may have to re-route your wiring if noise is being...

Great links guys! :D

I am not just book smart... :shock: My comments/questions have been based on two specific systems operating at 25kW and 35kW++ in mobile applications and I am trying to figure out what is real and what is distorted (myth). I will also keep asking questions until my curiosity is...

55 has been very upfront and I appreciate his comments, but I get the impression that the power system design is more of a trial and error than design for reliability. My concern is about all of these claims of "Performance" that can't be quantified. As a side note, 55 provided details of...
