My multi system VCR139 CRT monitor
3 Attachment(s)
I Started this monitor in 2017 and experimented in higher line rates other than standard NBTV 32 line 12.5 rates
Did a fair bit of work with this little CRT build is here http://www.taswegian.com/NBTV/forum/viewforum.php?f=31 We have FreeNBTV software can use any thing you want line rates up to 240 line found here http://www.taswegian.com/NBTV/forum/...=2458&start=45 Well only limited to the bandwidth of your sound card so that limits you to the video quality not the line frame rates ...so what i did to keep the video Quality with the bandwidth possible for the highest line rate was drop the frame rate below is 240 line 2 hz image is still viewable sort of a cross between SSTV and NBTV . I call it SNBTV ; ) slow NBTV ! short you tube video below and camera results slow enough for the cameras shutter to pick up all the image . https://www.youtube.com/watch?v=4qoeoWDusQI |

If it works out and i can power this beast it has 2 electron guns and 2 deflection plates i might be able to do what i am doing here on my binocular monitor on one crt https://www.youtube.com/watch?v=NnOemQof-6U But i want to go 120 180 240 with low band width select as in low 2 hz frame rate since i don't have a system converter and i can make the video on the pc and use its sound card be horizontal scanning |
