Because of the cost of electricity GB3ZZ is now operating as a "part time repeater" (0900-1300 & 1530-1830 GMT).

The streamer operates from 0730-1900 GMT.

Locator: IO81RM.

Location: Filton, north Bristol.

OUTPUT - 1316MHz DVB-S2 1.5Ms/s H264 FEC1/2 horizontally polarised, now single channel Portsdown transmitter.

23cm inputs 1249MHz DVB-S 4M/s H262 and 1249MHz DVB-S/S2, 1.5Ms, 1Ms, 500ks or 333ks, H262/H264/H265 Ryde scanning receiver, all horizontally polarised.

There is a vertically polarised input on 437MHz, DVB-S/S2, 2Ms, 1.5Ms, 1Ms & 333ks, Ryde scanning receiver. The sensitivity of this input is much less than the 1249MHz inputs because it shares a dual band vertical also used for 144.750MHz talkback monitoring and does not have a masthead pre-amp.
