If N2 oscillates at all, it will oscillate at 10.7MHz. Driving that through the N4-6 will square it up and produce harmonics, but the ninth or tenth harmonic (which is what can be tuned by a 88-108 Mhz FM receiver) will have an effective radiated power which is tiny. You will be lucky if you can receive it over a distance of a meter.
What about veroboard for the VHF and breadboard for the audio.
BTW I forgot to mention, I'd love to have the transmitter running on a audio line in from a computer audio out port. How strong is the signal, can I bypass all the audio amplifier stages if I use the jack input, or what about the jack and a pot?
that sounds complicated. but about the audio line, well it can power a speaker loudly than that of a electret mic with that amplifier on the transmitter design.
of course I'll use a power supply, but I am just wondering about using the signal from the audio lines.
Well, I am reading the mod4 thread as soon as I started this thread, pg 19 now.
I am going to try that transmitter, the only thing that bother me is the trimmer, the only component shop in my town only have 1 - 10pF trimmer. I have to get my friend to try another town 100km down the road in the weekend. I am just 17 so, no online purchasing or anything, and no funny equipments but I'll make it.
how about a 5k pot in series with the signal input?
on the output jack there's GND left and right, If you want to combine left and right channel what can you do, connect them together? or just ignore one?
