M1KTA announced he will be QRV as E51KTA on MP73-N narrow band SSTV from 10-20 March. It would be cool to at least receive him. Transmitting on the 10.132 MHz NBTV frequency is a problem as we are not allowed to use that mode below 10.140 Mhz as far as I know the rules in the Netherlands. I never heard of this narrow band TV mode before but is sounds interesting. You can receive it with MMSSTV. Personally in his situation I would prefer FSQ as it has message capability and at the same time you can send pictures with (almost) the same quality as MP73N.
A nice page to read about NBTV is the K2UK's Quick and Dirty Guide to Narrow Band TV wikipage.
I was not aware this NBTV seems to be populair as there is even a N-SSTV group you can find it here: https://narrowsstv.wordpress.com/
I will be monitoring 10.132 MHz SSTV at least this weekend and hopefully I'll catch a picture....
