On the 9th April 2015 at 2pm we turned on the 3408 MHz transmitter so GB3HV is back on air after 5+ years!

The transmitter uses a DTX1 encoder and modulator fed at 830 MHz in to a modified Airspan board to give 3408 MHz. The output is fed up the co-ax with 28v DC to a DB6NT amplifier at mast head which gives about 13 watts in to a 10 dB slotted wave guide antennae.

The signal is DVB-S 2 Msymbols with an FEC of 2/3 giving a 2.4 Mbit/s useable bit rate.

To receive the signal you will need a C band LNB (http://www.amazon.co.uk/dp/B00HVM6LFS/ref=pe_385721_37986871_TE_item) and a FTA digital receiver.

HV has been received by Rod G8DGR on a 2 foot dish at home and G8GTZ has received it on an LNB only at a number of sites.

Thanks to Dave G8ADM for supplying various materials and Tony G1HBD for sorting out the aerials.

We look forward to your reception reports!
