Back in the mid-1960's Novices could run phone (AM in those days) on 145-147 MHz. The Heath Twoer was a cheap (for then) and simple kit rig that was very popular. I and quite a few of my teenaged friends got started on hamming this way. 2 meters may be too crowded most places for that today, but it would sure be nice if a cheap simple rig like this could recreate those times for today's kids. 73 de KC7IT -- Mike Butts, Portland, Oregon mbutts@netcom.com ------------------------------ Date: 26 Feb 1994 22:51:22 GMT From: news.larc.nasa.gov!grissom.larc.nasa.gov!kludge@ames.arpa Subject: Fcc Refulations.

Any >idea as to the efficiency of such transmission? Lots and lots of regulations apply, and you can find them by going to your school library and asking for the FCC regulations. Which part you want depends on what sort of license you want (and you will need a license to do this, indeed). I recommend looking at the experimental service. Apply for an experimental frequency somewhere between 50 and 500 MHz... the FCC will assign you a frequency wherever they have space. I think that FCC Part 73 is the place to look, but in the case of the experimental service you can basically do anything anywhere if you can convince the FCC that it's important, and you can't do anything at all unless you can. It's designed for stuff like this. Go to your local FCC field office and explain what you want. They will give you the appropriate paperwork, and really tend to be quite helpful. Expect about a year for the experimental license to get processed. --scott -- "C'est un Nagra.

All the sinal needs to be is a pulse or a steady tone in which it will send a high output into my circuit which will then activate a device of mine. If anyone could provide a scematic Digagram on how to build on of these, I would appreciate this very much...Also if someone cannot answer this, could refer me to a book which would cover projects of a similar nature....Thanx, ________ ____ / / / / | Internet: / _____ ____ /___ /___/ ___ _/_ | JOlson@micromed.com / ___ / / / / / /__/ / | / _____ /___ / / / / / / /_ | PROUD GSAUG MEMBER! -- jolson@micromed.com (Jason Olson) ------------------------------ End of Ham-Homebrew Digest V94 #45 ****************************** ******************************
