Radio Frequencies of interest
|
||
to Telephone Experimenters
|
||
by THE RESEARCHER
|
||
(Updated 01/26/86)
|
||
|
||
A lot of technicaly oriented telephone experimenters are finding out about
|
||
an exiting world of telephone activity in the radio spectrum. Most of you are
|
||
probably aquainted with mobile telephone channels in the VHF band and know that
|
||
these conversations can be monitored. Frequencies have been allocated in the
|
||
VHF and UHF bands for use by land mobile, marine and air-ground stations.
|
||
Another facinating group of frequencies are the high seas channels in the high
|
||
frequency short wave band. I have spent many hours recently listening to ship
|
||
to shore telephone calls from ocean liners on the Atlantic.
|
||
Scanner radios are used to monitor the VHF/UHF channels. To listen to the
|
||
high seas channels you will need a short wave receiver capable of copying
|
||
single sideband transmissions. Nearly all high seas calls are transmitted on
|
||
upper sideband.
|
||
The new cellular telephone channels lie between 825-845 MHz and 870-890MHz
|
||
There are 666 of these spaced 30 kHz apart. I am aware of three manufacturers
|
||
who make scanners capable of receiving these frequencies. They are ICOM America
|
||
(IC-R7000), Yaesu Electronics Corp. (FRG-9700) and Regency (MX-7000). Ads for
|
||
all these can be found in "Popular Communications". There are convertors
|
||
available from Hamtronics, inc. which permit most scanners to tune these
|
||
frequencies. Their address is 65-B Moul Road, Hilton, NY 14468-9535. Phone:
|
||
716-392-9430. The cost is $88.00 plus $3.00 shipping and handling.

The following is a list of the channels used for high seas phone calls.As
|
||
a rule, the 4 MHz band comes in best at night while the higher channels are
|
||
best received during daylight hours. All frequencies are in kilohertz.
