I know the talkback freq is 144.750Mhz
but the actual datv signal
going by the wiki
Code: Select all
The UK allocation is from 1240 MHz to 1325 MHz and common ATV usage is as follows:
1248 - 1249 MHz = repeater inputs
1255 MHz = simplex
1275 MHz = simplex or alternative repeater input as determined by the CAA (primary user).
1300 - 1325 MHz = repeater outputs
but as per the rsgb bandplan
In order to prevent interference to Primary Users, caution must be exercised prior to using 1250-1290 MHz in the UK.
I know there are different SR and FEC to use. this give over 30 different combinations not forgetting dvb-s and dvb-s2 & mpeg2,h265,h265
so is there a default tx calling ie 250 fec 3/4 or 333-7/8 dvb-s h264 and a freq
so people can just leave a reciever running in the shack and not have to twiddle
yes the fm is easier just leave it on a freq and wait
and don't get me asking about repeaters. trying to find out what some are on what sr and fec ect. even on the repeaters own webpage you have to hunt for the info
