Thank you Robert, et. al, The device is FM modulated. It is a Futaba 9CAP transmitter and a buddy with a coaxial dynamics watt meter measured the output at a little less then 100mW. Although I am fairly confident in my electrical skills for building kits and building/repairing power supplies, the RF...

This is in the 6m band, 50.860Mhz to be precise. The current output is less then 100mW, I want to use the full 1W I am legally entitled to. The car engine analogy works for me. I didn't realize the 'system' approach to it, but I understand now, thanks! I guess it is a bit more involved then I imagin...

need some advice on replacing a transistor
I have a R/C transmitter that uses a 2SC2314 transistor. According to the ARRL handbook, I am allowed to transmitt with up to one watt of power on 6M. Would anyone have any advice on what transistor I should replace my current output transistor with? Here are the specs on the current transistor: htt...

need a 9v cut off switch, any ideas?
Hi,
I need a circuit that will turn off if the battery reaches 9v. Specifically, I am using 3 lipo batteries to power video equipment and I don't want to over discharge my lipos. Any ideas? Thank you very much, your help is much appreciated.
