23cm DATV transmissions
Posted: Mon Jul 12, 2010 10:35 am
The GB3IV ATV repeater on the Isle of Whight (Stenbury) now has DATV transmission capability using QPSK 4MS/s FEC 3/4.
The Net night is each Monday begining at 8 pm om FM ATV, with a change to DATV at 9pm, please have a look on the output frequency of 1316Mhz at 9pm all, reports would be welcom on this forum.
The repeater has DATV input capabitly on 1249MHz 4MS/s FEC 3/4 and 70cm on 437Mhz 2 MS/s FEC 3/4 though at present a DTMF tone on 434.550 MHz is needed to activate the DATV input, it is hoped to make this an automatic c/over in the near future when a valid DATV signal is seen.
For the moment the normal input I/p 1249Mhz FM and send dtmf A2* for 23cm DATV restore to FM rx with A2#,
or 70cm DATV North beam is BB6 and restor to FM 23cm rx with BB1.
