Not many people are aware of the new 15
channels which have been added to the
VHF cordless telephone band. In response to that, I have decided to create
a little chart of all the allocated
frequencies for each
channel. Note that
the original channels 1 thru 10 have been changed to 16 thru 25.

If you want to hear both parties, then you must listen to the
base frequencies.
However, if you need to know who the party on the
cordless telephone is, then
listen to the
handset frequency.
Cellular Telephone Frequencies
The cellular band is in the 869.010 to 894.000
Mhz range, in 30
Khz steps.
That makes a total of 835 possible
frequencies to
scan.
