MOBILE TELEPHONE
, Information from[ eee
Pacific Northwest Bell Telephone Company, Longview, Washington. BIC
In event a trailer is used as a base of operations for the
search operation a completely mobile telephone installation could
be made in the trailer on one week of notice to the phone company
(time element could be lowered to possibly three or four days)
with the trailer to be left at the mobile shop, 906 New York Avenue,
Longview for the better part of one day for, the installation.

| Mechanically we would need a 12 volt car battery in good
| or new operating condition as a source of power.
The mobile unit would have one or more channels depending
upon the area we worked in in order to insure that we could get to
a mobile operator to place our call to any number,
Cost - one channel $32 per month and for each additional
channel $3 per month. Possibility of having to use 3 or 4 channels
exists in order to insure ability to reach a mobile operator at
some location such as Longview, Portland or Hood River, Yregon.
|_havised using the car battery - 12 volt ~ in good b6
condition would give us indefinite service since the drain on bie
the battery is not great if the phone is not actually in use.
Cost of installation of the unit is $50
Installation of such a unit would not involve us in Line
hookups and we could be completely mobile.
Procedure on calls from any location to the mobile unit
would be - dial Long distance - ask for mobile operator - give her
number of the mobile unit (each channel used would have a different
mobile number) - she would then select the channel she could reach
and the call would be made,
Security - same security as on normal telephone Line.
