a mates been hearing it a while now on and off say it's someone just keying the mic up and not talking,
i heard it yesterday, traffic in the background, voices, not near me as such but everywhere i drove no good signal either,
but voices, traffic sounds in the background..
now 458.800 is UK general right ??
so 5w handy.
ok so today it comes on again 8.50am full signal.
no audio.
i'm thinking Hive, or digital electricity senders,
so i went out mobile (had to go out) on my own estate heard it with no antenna, no CTCSS no DCS hits either.
but i was hearing it over a couple of miles two on a handy..
only thing i noticed was in the air was the local radio traffic watch thing that does updates to the radio stations.
nothing on WTR Browser (i have the software)
it's a UK General channel so i assume could be anyone,
but the coverage was massive, strong and clear,
i'll listen again later nearer the going home traffic times and see if it is the new media helicopter thing..
other than that i don't have a clue..
