"Welcome to McDonald's. May I take your order
please?"
That's what you'll hear if you monitor 154.600 MHz near
Yorkville or Montgomery, Illinois. As my article pos-
ted last April described, McDonalds restaurants in this
area have been using radios to communicate with cus-
tomers at the drive-up windows [see article below].
Although low power transmitters are used, I can monitor
the McDonalds restaurant about 2 miles away using a
Butternut SC3000 antenna at 20 feet. So far, I can
hear only the waitress side of the conversation. The
customer side of the conversation may be conducted over
a closed circuit intercom.
Articles in the November 1985 issue of "Monitoring
Times" claim the McDonalds operation to be nationwide
on 154.6 and on 35.02 MHz in Barberton, OH, although
the latter frequency has not been confirmed here.
