The Private Mobile Radio Story

The Private Mobile Radio Story

The Private Mobile Radio Story

Ever wish you could talk to someone who wasn’t
within earshot? Like contacting ski partners back
at the lodge? Or letting a friend know how to find
you in a busy shopping centre? Cobra’s MicroTalk
radios are a great way for friends or family to
increase their fun - and safe ty - by staying in to u c h
while on the go and they are pe rfe ct for business
use as we l l ,such as office to wa rehouse co m m u n i­cat i o n s.

The ERC (European Radiocommunications

1

Committee) has created 8 channels,called Private

Mobile Radio (PMR). These channels are in the
UHF (Ultra High Frequency) band which means
great penetration through buildings,thick forests,
hills,and other dense structures.They are also FM
(Frequency Modulation) signals which means
crystal-clear reception even in crowded noisy
environments.
