Some tests today just on FM first tired Fax 480
FAX480 was developed to provide for relatively high resolution image transmission on HF, VHF, and UHF amateur radio bands. FAX480 was designed to bridge the gap between conventional slow scan television (SSTV) and conventional facsimile techniques

Next tried the same video as past gos in FM


Here tried 30 line Baird Ronnie Barker Porridge clip just make him out in bits i think the voice channel is mixing with the video here


recording the above video on the lathe shown below


I ended up removing the platter plate glued down causing a little bit of a up down side to side wobble in the line play back as the play back cartridge follows .
I tried up to 60 line but just getting blob shapes ,So have tried AM PWM and FM now
