  1. OK. So I finally got around to testing the output of my 900mHz vidTX today, and the results were very dissapointing. Here's my setup: I used a Tektronix 2711 SA. I attached the TX directly to the input with a 6" piece of RG-142 coax, using the internal 30dB attenuator. Peak output was 22.5dBm, which equates to roughly 177.8mW nominal. Now I realize there will be a slight loss in the cable, but it shouldn't be more than half a dB, at most. This is very dissapointing, considering the TX is advertised at 500mW. I plan on opening this thing up and trying to fine-tune it for better performance. Has anybody already done this? Any pointers?
  2. Thanks for your suggestions everybody. I guess have a lot more research to do. Although I want to keep it simple at first by using the basic stamp style chips, I do see the value of going to the "C" language based options for the ability to get more complex/powerful programs. Man, this is tough. It was easier to decide on my last car.
  3. Thanks for the info. I'll check it out right away.
  4. Ok. here's the deal. I'm a seasoned electronics tech, so I know my way around the stuff. My problem is that I don't know much about microcontrollers and would like to get into this the right way. The right way being, that I want to start small and relatively cheap, but have the ability to grow without having to spend a lot of time/money to expand my capabilities. I have been looking at starter kits, but don't see too many that allow you to program and remove a chip to put in an external circuit though. Am I mistaken? I also need to keep the chip/circuit small and light for RC use. This all stems from my desire to duplicate MR RC-Cam's "Nav-Lights" project, and that is my immediate goal. The problem is that it's a fairly old article and I'm not sure if/how the technology has changed. So far I've been looking at stuff from "Microchip Technologies", "Parallax", and PICAXE. I would like to be able to duplicate the "Nav-Lights" project without being limited to having to do the "One time burn" routine if possible. In other words, I would like to be able to use the RAM based technology if possible. I'm not dead set on it though. Any advice would be greatly appreciated.
