6.12 MAKING TELEPHONE CALLS
To make a radiotelephone call, use a channel designated for this purpose, The
fastest way to learn which channels are used for radiotelephone traffic is to ask
at a local marina. Channels available for such traffic are designated Public
Correspondence channels on the channel charts in this manual. Some ex-
amples for USA use are Channels 24, 25, 26, 27, 28, 84, 85, 86, and 87. Call
the marine operator and identify yourself by your vessel’s name, The marine
operator will then ask you how you will pay for the call (telephone credit card,
collect, etc.) and then link your radio transmission to the telephone lines.
The marine telephone company managing the VHF channel you are using may
charge a link-up fee in addition to the cost of the call.
6.13 OPERATING ON CHANNELS 13 AND 67
Channel 13 is used at docks and bridges and by vessels maneuvering in port.
Messages on this channel must concern navigation only, such as meeting and
passing in restricted waters.
Channel 67 is used for navigational traffic between vessels.
By regulation, power is normally limited to 1 Watt on these channels. Your radio
is programmed to automatically reduce power to this limit on these channels.
However, in certain situations it may be necessary to temporarily use a higher
power. See page 20 (H/L key) for means to temporarily override the low-power
limit on these two channels.
6.14 DUAL WATCH (TO CH16)
1. Adjust the SQL knob until the background noise disappears.
2. Select the channel you wish to dual watch to CH16.
3. Press the [DW(IC)] key. The display will scan between CH16 and the chan-
nel that was selected in step 2.
If a transmission is received on the channel selected
in step 2, the QUANTUM will dual watch to CH16.
