Here's results on my PhonoVision recorder player on the SSTV recordings ,shown 8 sec .
Slower the system harder it is to display correctly but work in progress and reason i made a MK3 to try and correct its problems .
I find it records PWM better than AM and SSTV FM seems ok too .
I have tried NBTV but framing is very wavy i think due to the rubber pulley belt .
At the moment i am changing the platter to direct drive and dropping the pulley idea ,MK2 was fiction driven and that wasn't to bad even on slow NBTV recording around 33rpm .
I Still have to master the NBTV side here as the recordings are still a bit poor to say the least but i hope the swap to direct drive with improve things .
I also would like to try different system recordings within its band width this time around push its limits in time .
