Re: [digitalradio] Digital Video on 12.5khz channel

It would be of no use to the US hams as we are limited to 5KHz on 2 meters.   Joe Ivey W4JSI   ----- Original Message ----- From: Patrick Lindecker To: digitalradio@yahoogroups.com Sent: Thursday, June 08, 2006 4:46 PM Subject: Re: [digitalradio] Digital Video on 12.5khz channel Hello Sam,   >If it interests anyone, then I can publish a specification for people >to look through? I would be interested to read your specifications and also interested to know what sort of compression system you propose (Runlength, LZW, DFT...?).   Note for information: in Multipsk, I've proposed a DIGISSTV mode for Packet (specification on my WEB site).   73 Patrick   ----- Original Message ----- From: Samuel Hunt To: digitalradio@yahoogroups.com Sent: Thursday, June 08, 2006 2:30 PM Subject: [digitalradio] Digital Video on 12.5khz channel Hi All, I have been working on a protocol that will allow around 125kbits/sec data to be transferred in a 12.5khz channel. However, it requires a S:N in the channel of around 35dB. The potential use that I've thought of is for ATV, with a local 2/70cm repeater that outputs reasonable power and users all use Yagi antennas to recieve the transmission, much like with 23cm ATV, except it's on 2m. If it interests anyone, then I can publish a specification for people to look through? Sam M1FJB __._,_.___ Need a Digital mode QSO?
