A Remote Channel-Changing Fixed Repeater System designed To
Remove The Need For Leased Telephone Land-Lines.
A number of teams in the Lakes use remote radio sites that are controlled over a
leased telephone line. These have been found to be both expensive and prone to fail-
ure from all manner of events from lightning strikes to a not so gentle shove with an
earth-mover. Because of this I looked at methods of using a radio link rather than a
land-line. Microwave links are expensive and so are not covered here although if any
team has any documented information on their use, I’d be happy to include it for you.
The chosen method was a closed, simplex link channel which can be anything you
have a license for that is not in the same band as the UKSAR channels, here I mostly
use the low band channels between 71 and 86 MHz although I have used UHF
channels with equal success but not over the distance afforded by low band.
As in the system developed by Dave Binks, this uses modified radio software not normally available but it can be arranged by contacting Rob Brookes.
