| some info |

yeah I figured people would be more interested in helping me if I told them what I'm up to. I want to convert an itrip to broadcast at this axact frenquency (155.1750). why would I want to do this? I want to use the walkie talkie that I have in my delivery truck as a radio reciever since I don't have an actual AM/FM/CD reciever or player... It would also be fun to mess with some of my co-workers too! All in good fun of course.

We can set you up with such a transmitter.
However, audio quality at 155MHz with a narrow-band receiver
will be poor when compared to regular radio fm receiver.

Thats cool that the quality will not be up to par with an fm reciever but I would still like to try. I really just want the novelty of making something that works, and music while making deliveries.

Check the schematics section than.
It will not be easy, though.

It won't be "a schematic" exactly for what you want.
This will require writing software, among other stuff.
Free running oscillator will not cut it, you need PLL and PLL requires
a microcontroller and some software.
Probably out of your league at your level of knowledge.
