Another problem is the way private insurers try to risk-select, in umpteen subtle ways, even when there is a risk-adjustment system to make that less inviting.
Whereas traditional systems require the use of one or two dedicated channels per user every time there is a two-way communications, trunked systems automatically select the voice channel that a user may talk on every time he transmits.
It didn't take the community long to catch up, though -- the homebrew channel was working its way onto select systems using tried and true methods since launch day.
Switching involves looking at an element of the screen and giving a big blink to select -- the display seems adjusted in such a way that normal blinks won't trigger it, so you're less likely to accidentally set something off.
The review of the report is under way with a public process meeting at the council's civic hall before an all-day select committee style hearing on 21 November.
