27MHZ 2-way radio?

I need help building a 27MHZ 2-way radio, as the title suggests. I really want to build one so I can learn more about how radios work. And it has to be 27MHZ. I would also prefer the transmitter and receiver to be separate circuits, so there would be multiple uses for this.
Thanks in advance,
Dan

You may be able to find schematic with a google search. Unfortunately even with good schematics and a known good board layout you will run into problems requiring specialized equipments to get sorted. Something as small as a through hole in your board being too big or inconsistent solder joints can cause problems. Every micro farad in radios counts. Radios are kind of a complex subject that require more than building one. So pick up some books and start studing the subject. Then once you have an decent understanding take a stab at building something simple before moving up tot he higher frequencies.

1. Check out local regulations re transmitting.

2. Making radio transmitters and receivers is REALY difficult - your going to need some test equipment, so this may be a long and steep learning curve.

3. It's not by any means impossible for someone who is determined. Do a lot of reading and good luck

I would start with the receiver. 1000.s of circuits available on line.
