Trawling through the posts in an effort to catch-up on NBTV activity I stumbled upon your posting "SSTV NBTV" and was very interested in the item about fft-tv.zip
I have experimented with Con's software in the past so I was delighted to learn of the existance of fft-tv.zip though sadly a quick search on the Internet revealed only a couple of dead links for that package.
Would it be possible for you to e-mail me a copy of the zip as I would like to give that one a try?

Thanks for responding and for the pointers to Chris Long. Sadly I dont have a Facebook account but I may be able to find a work around
Re Free NBTV, I did try that one but have (so far) not been able to get it working on my laptop. When time permits I will give it another go on my old desk-top machine. It really is an impressive looking software tool for nbtv work.
Thanks again for taking the time to respond.

Thanks for the reply and for the pointers.
I am pretty sure it was the newest version of Free NBTV I downloaded/tested but I will double check next time I fire-up the laptop and also make a note of the errors.

I have downloaded the newest version (again) from here...

... and will try it again and let you know what errors/problems arise. So many "boxes" with error messages popped-up last time I got confused but I will make a point of reading them all next time and noting down the specific error messages.
Thanks again.

Prompted by your last e-mail response I had another go with the current version of FreeNBTV software I downloaded a couple of days ago and I am pleased to report it works this time
I took the precaution of using a different laptop this time around with Windoze7 and an otherwise empty hard disk so no possible corruption of system files etc from years of install/remove software Hi. Its early days yet and I need to explore all the different options but its allready clear that it will be a useful testing tool for any non-standard NBTV mode experiments. Perhaps its time I re-read the original posts about FreeNBTV to see if any addition documentation or user instructions exist so I can take full advantage of the software.
Re the ZL1BPU software(s) for NBTV over HF links, I downloaded those a few years ago but sadly never got around to trying any of them but they do look promissing and fun
BTW Harry, what Windoze version are you running with the ZLBPU software? I note on the website he comments...
" It is designed for Windows™ XP. At present there is no software for other operating systems."
Its not a problem as I now have a third laptop with Win7 installed so (in theory) I can now replicate your "audio over the air" experiment but I just wondered if you had managed to run it under some other Windoze version.
Thanks for helping to restore my enthusiasm for image communication

I also share your concern about the coupling capacitors and longer time constants with higher load impedances causing the video waveform to "bounce about" a little.
