Low power device walkie talkies

Post by ryan_paul » 13 Jul 2006, 15:07

Dear all
Has anyone come across the low power device walkie talkies? (also known as LPD)

They have 69 channels and can use CTCSS codes and output at only 10 MW. Presumable they are illegal to use in the UK as they operate in the NFM section of the 70 cm amateur radio band.


Any info would be interesting.
Cheers.

They are for use in European countries that have different band allocation to the amateur band in the UK, so they are not legal for use here.

To make matters even more interesting, some of the channels are on repeater input frequencies. Which means, if you happen to use the correct CTCSS tone, people may be able to hear you for tens of miles but you would have no way of hearing the reply (as it's on a different frequency). Having said that, you would have to be pretty damn close (or have very good LOS) to the repeater to fire it up with only 10mW!

It's also worth mentioning that repeaters cost LOTS of money to establish and maintain (thousands of pounds) and amateurs tend to get a bit upset if you interfere with their repeaters.

Dear 2H2UZ

Thanks for the info.

Having operated GMRS repeaters in the past (abroad) I can quite understand how upset a repeater operator might be if a non licensed interfere with it.

However more worrying is that 70 cm band is allocated on a secondary basis and some of the LPD walkie talkie frequencies are used by the MOD in some areas.

Its bad enough interfering with Hams but quite another matter when causing interference to the MOD even if the device only kicks out 10 wm.

Dear 2H2UZ
Quite so I guess we all make typos sometimes.

Cheers.
