Is there any places in the UK where you can get 1mhz oscillators(postage is quite a lot from America)? Secondly, would grounding the computer controlled transmitter extend the range?

Also you said in another post about recieving a 28 mhz signal;"The Ramsey FR10C should work fine.
My ICOM will do a better job though." I looked at the Ramsey one and it said it was FM. How would it still be able to recieve AM?

RS components have 1 MHz oscillators. I bought a couple a few weeks ago for a couple of quid each.

I just built the permanent version of the Computer controlled transmitter. While it is transmitting, the sound is very fuzzy and just plain bad sounding. When I switch from low tone to high tone on the program, there is not even a slight change in pitch on my receiver. I know for a fact my receiving radio is set correctly to 1000 Kilohertz, and I have checked every possibility of a short circuit on my board, but everything checks out. My oscillator is from electronics goldmine and only rated for 5 volts, but when I used my second oscillator from the same place in the normal AM transmitter it worked perfectly. I am at a loss at what to do. Any suggestions.
