Playing Pianos via CB Radio
By Andy Taylor

Hi gang:  Thanks for all the responses on this subject.  it had been
most interesting.  I conducted an experiment via CB (Citizens Band)
radio to see if my theory will work.

Armed with a QRS CD, I modified the CB radio in our car with a audio-in
jack.  Flipping a switch on the site of the radio would connect the
audio out of the CD player to the CB modulation circuit, at the same
time the switch would also activate the transmitter on the CB also.

We had the CB base station radio at the house.  This unit had a switch
that would switch the audio-out from the speaker to the analog-input
on our Pianomation unit.

I sent the signal on CB channel 12 at 27.105 MHz, AM (amplitude modula-
tion).  All of a sudden the Foster began playing "Ain't Misbehavin'".
There was no problems.  Seven miles range was about it; if the CB band
had been quiet, there would have been much more range.

So I am leaning more toward an analog approach of sending MIDI
information.  It seems to me that any program that has audio output
would be idea for this.

The next experiment to see if this can be done over the telephone.
If someone can shoot me an analog MIDI signal, via phone line, I'd
like to hear from you.

Best Regards
Andy & Chris Taylor
