Hi Guys Smile
A failed analogue AV sender!
I’m probably doing something I shouldn’t with these picture links.
I remember Photobucket links didn’t go well with this forum, but here goes nothing:

Image Link

Image Link

I’ll see if I can edit to fix the links after posting, but anyways, the RF amp does work, in that the output is stronger than the output of the universal VHF modulator, so I assume the transistor is being driven, but 5-10cm for a colour picture is a little less than the range I expected.

I didn’t really want an electronics project out of it, but the commercial units aren’t easy to find on eBay either.
Any advice would be appreciated. I realise these bands might have been reallocated which is why I was trying to keep it weak, but not quite this bad!
Cheers, Brek.

A valve a day keeps the transistor away...

Images load for me, albeit slowly.

Imgur seems to be a popular alternative these days.
