Brainstorming
Well how much is hard to answer. I've seen one you could build for under
$40.00 if you can handle surface mount. Look in 73 Magazine within the
last 4 months for the Micro ATV transmitter article. To purchase the
devices prebuilt you are probably looking at $125.00 and up. Not including
cameras. But remember, you must have a valid Amateur Radio ( HAM ) license
to operate these transmitters. But, with NO-Code Technician license now
available, that's not a problem. There was also an article in a past Radio
Electronics on a pretty high powered ATV transmitter kit / construction
project. Hope this helps. If you are REAL interested in Amateur TV I would
suggest looking the HAMNET on CIS for more info / license info / study
guides.
