Local VHF Channel Usage

ICOM VHF radiosProper use of the VHF channels is an important safety factor. Channel usage in the Solent and Southampton Water has some differences from that in other areas so we have compiled this guide.  VHF call signs are indicated as e.g. "Solent Coastguard".

N.B. Ensure that your VHF is set to "INT(ernational)" not "US(a)"! Radios operating on USA channel settings will not hear the reply from an NCI Station (on ch.65), from a Marina (on ch.80), or receive the new Marine Safety Information channels (ch.62,63,64). New radios are often set to "US" when bought; use the menus to reset them to "INT".

DISTRESS, SAFETY and Calling Channel
Channel 16 Channel 16: Emergency calls to HM Coastguard ("Solent Coastguard"). Not to be used for routine calls - for routine calls to HMCG call direct on channel 67 (see below). Calling Channel: users must transfer immediately to a working channel (normally 06, 72 or 77)

Solent Coastguard

Channel 67 Channel 67: In the Solent area is monitored by the Coastguard ("Solent Coastguard") for routine small boat traffic; call direct, not via channel 16; but for radio checks, to minimize Coastguard workload,  call the nearest NCI station on channel 65 !
