BATC Forum

Hello all,
A few years ago I bought the Quadrant DVB transmitter from Antennair.
The transmitter works fine on 70cm DATV here in Holland.
But now I have a question that I can't quite figure out.
There was also a second print that could be placed on the board
but I don't know what this is for.
Can someone explain to me what the second print is for? ?

Kind regards Jan

It allows you to run two separate programmes simultaneously in the same RF output.

Selection of the programme would be by changing the PID numbers in the receiver, sou you would use something other than the usual Video 256 and Audio 257 to get the second programme.

The bitrate/symbol rate needs to be at least double that of a single channel.

Okay Clive,

Thank you for the explanation.
I had no idea what I could use it for.
Also because the manual states that it can also be used on other frequencies.
Such as P1 / for 70cms - P2 / 1248Mhz and P3 / 1275Mhz
But I must have misunderstood that.
