pmr446 mobile

Here in Cyprus PMR446 is a license free radio system in line with the European Union Standard. It is well used especially in the cities and tourist areas by hotel staff, doormen at nightclubs, small boats and tourists both on foot and mobile.

In the homebase I use an AnyTone AT588 and UHF Collinear homebase antenna and a Jintong JT988 as my handheld. In the car I have a Midland GB1 PMR446 Mobile with its attached mag mount antenna (pictured). I monitor Channel 8 with no CTCSS. If you are in the Paphos area give me a call.

Legalities

ECC/DEC/(05)12 - European law covering Digital PMR446 Radios

ECC ERC 98 (25) - Harmonised frequency band for PMR446 Analogue Radios

.

Although in the UK and other countries PMR446 is used as an unofficial UHF CB radio system, in Cyprus it is generally used as it was intended, as a short range means of communication because in Cyprus CB radio never took hold. In addition to the legal 500 mw handhelds some users use imported Chinese handhelds programmed up for the PMR446 frequencies and running 4 or 5 watts.
There are now 16 analogue Channels available for use on PMR446

Channel 08 CTCSS 08 (88.5Hz TX only) is the International DX Calling Channel (No CTCSS on receive)

DXing on PMR446

Propagation of radio signals at 446Mhz is generally by line of sight so the higher up you are the further you can reach. In cities and built up areas although the range is much reduced signals can still reach their destination via reflection off of buildings, this is called 'refraction' but in order to get distance (DX) contacts get yourself up onto the top of a mountain or on the roof of a high rise block of flats if in a city.

DX is an old telegraphy code that means long distance. 446MHz, even with just 500mW, can travel long distances from good high locations, and is sometimes helped along by special atmospheric conditions known as 'Tropo' or 'a lift' so there is no reason why we can't enjoy this fascinating aspect of PMR 446. So next time you head for the hills when there's a good lift - take the PMR446 and monitor channel 8,  put out a CQ call giving your callsign and location - you might get some surprising contacts! 500mW ERP during good tropo will easily reach up to 100 km and if you are using modified equipment much further.
