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.

CH    BASE   HANDSET    CH    BASE    HANDSET

1       43.720   48.760          14     44.460   49.460
2       43.740   48.840          15     44.480   49.500
3       43.820   48.860          16     46.610   49.670
4       43.840   48.920          17     46.630   49.845
5       43.920   49.020          18     46.670   49.860
6       43.960   49.080          19     46.710   49.770
7       44.120   49.100          20     46.730   49.875
8       44.160   49.160          21     46.770   49.830
9       44.180   49.200          22     46.830   49.890
10     44.200   49.240          23     46.870   49.930
11     44.320   49.280          24     46.930   49.990
12     44.360   49.360          25     46.970   49.970
13     44.400   49.400

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.
