PMR446 Channels can be listened to remotely through the internet using a WEBSDR.
A WEBSDR is a remote SDR (Software defined radio) reciever that is accessible through the internet for the general public to listen to.
No radio apparatus is necessary to listen to a WEBSDR, simply an internet connection
Many WebSDR's only support listening to the amateur radio bands, however a select number do support PMR446. Simply visit the links below to explore and listen.
It is interesting to compare PMR446 activity in different regions, as well as using it as a remote test reciever to test your transmission if you live close enough to the SDR.
