The 'Hellcat MK I' 625-32 Converter.

Postby Steve Anderson » Mon Jun 06, 2016 6:23 pm

Somewhere on this forum I'm sure I started a thread on this subject, but even using the features of the advanced search was unable to locate it - that's if it does actually exist. Should anyone trip across it I'll be interested to know of its existence.

Basically standard analogue 625 in, monochrome NBTVA 32-line out.

I've decided to continue with this as the hardware appears compete and it seems I'm someway into the software, so results should be reasonably rapid (says he).

It took a while to locate the hardware in amongst dozens of boxes, but it's seen the light of day for the first time in at least two years as a guess.

To jog memories a snapshot is below.

The electromagnetic spectrum has no theoretical limit at either end. If all the mass/energy in the Universe is considered a 'limit', then that would be the only real theoretical limit to the maximum frequency attainable.

Thanks Harry.

I've only quickly skimmed through it, it seems a bit thin on the ground regarding details. Though it does give me an idea of where I had got to. I'm at the stage of refreshing my failing memory and trying to work out what in the heck I was as far as the software goes. Although I like to think I'm quite disciplined when it comes to commenting code, sometimes my own comments defy me!

Thanks again Harry,

Steve A.

No worries Steve ,I think every one here has the inventor in them and there never seems to be enough time for every thing so projects get put aside for the next idea to try and getting back to a past one is always hard.
I think you wanted to keep this one detail wise for the news letter ,i would put it on both less chance of both getting lost in the future .

Yes, I've had a couple of 'prods' from a certain Editor over the past year or so...wondering what's happened...gentle prods I might add. So having mentioned it to said Editor in the past I guess I'd better get on with it!!

I haven't mentioned the NBTV-625 Up Converter yet. Keep quiet guys.

I think said Editor is just trying to get contributions in rather than being concerned with the quality or otherwise.

So guys, help the poor Editor out...

I'm quite willing to help out in converting a fag-packet sketch into something a bit more presentable if that concerns one. Also to proof-read items too. No excuses now...
