Llyswen provides
an improved UHF signal to an area of the Wye valley around Llyswen village,
Bronllys and Talgarth. Prior to its commissioning locals relied on Clyro,
Brecon or even Ridge Hill.
In
Llyswen village, only Ridge Hill provided a useable (though weak) signal.
This caused some interesting moments for aerial riggers working at the homes
of more fanatical Welsh speakers seeking S4C! More local transmitters that
provided the correct Welsh programme feed suffered from severe multipath
interference. Conversely, the allocation of group A frequencies for Llyswen
ruined weak (though perfectly useable) Ridge Hill reception for many in
Bronllys and Talgarth who had hitherto enjoyed Ch4 and S4C reception from
diplexed Ridge Hill (Midlands) and Clyro (Welsh) installations.
