The past few months, I've been doing a lot with #SSTV but one thing that has frustrated me, is the lack of public domain test cards that can be used.

I've been using the Philips PM5544 test pattern, which is a good one, but it's rendered for PAL resolution, which rarely corresponds to those used with SSTV.

Some have used BBC's Test Card F: but here is a problem -- it's copyrighted. Not sure how legal it is to use this. I'd rather not invite legal trouble using it.

The RCA Chief test card is a good one, public domain, but it is monochrome, and also not quite the right resolution for SSTV either.

I came up with these:

I'll make these available in the public domain, so use however you feel.

The trams are actually flying the Progress #Pride flag this year. Wouldn’t take much more (frequency gratings and a few vertical lines) to also function effectively as the Pride #Testcard.

@EricRijlaarsdam Nee, klopt! En het als bijvoorbeeld het Duitse #Testcard had het thema's; het ene thema sprak me absoluut niet aan, het andere was geweldig. Dus het verbaast me niet dat het destijds weinig verkocht... Maar het was wél een aanvulling op wat er bestond, en ook nu nog is een dergelijke kruising tussen literatuur en muziek best uniek.

Maar een relaunch zal er wel niet inzitten, papier wordt steeds minder populair en een ander goed businessmodel hiervoor ken ik niet.
