If you would like to help please share your valuable comments on one of my threads on antique radio forums ->http://antiqueradios.com/forums/viewtopic.php?f=12&t=247041&sid=2e470f0cceb6ea37a7ade0100a9105c1

I'm not really that much into antique radios or RF for that matter.Is that forum an Antique collectable radio restoration forum? Or were you looking for an "Amateur radio" forum, you know there is a difference right?To put you in the right direction you need an audio or function generator to drive the input at a suitable audio frequency.This is so that you don't need to key the condenser mic or even put one in the circuit. Your Protek looks suitable.For power you will need a dummy load in place of the antenna and you would measure the output with a True RMS multimeter.The formula is P = V^2/R where R is the impedance across your dummy load or antenna.I'd imagine you use a suitably ranged oscilloscope (or frequency counter/meter?) to tune your output frequency 100Mhz (FM).Spectrum analyzer could be used for troubleshooting but an overkill on your first RF circuit.You may also need a higher frequency function generator (than 3MHz) one day as well if you need to inject higher frequencies while building or troubleshooting circuits.Check out books like the ARRL handbook (there is a ton of books).If you can't understand your circuit keep looking at examples with a walk through or block diagrams for simple FM transmitter circuits, kitset documentation even.The antennas they mention are "ground plane antenna" and "multi element yagi" you can google this and click on images to show you.I used to have an AM transmitter and a "ringo antenna". As I said you don't need one to test just a suitable load.You can google all this stuff and trust me, I'm no RF expert - but I know roughly how that circuit works.We have some very talented guys on the forum such as w2aew you might be interested in some of his videos.
