  1. I think VHF is just referring to the frequency band. You can have different modulations at any frequency.

     

    If you think about a radio wave as a wiggly line going up and down, you can change how far up and down it goes (amplitude modulation) or how many times it goes up down in a second (frequency modulation).

     

    Phase modulation is when you make the wiggly line jump to a different part of the up and down cycle (so if it was going up and you put it 180 degrees out of phase it would suddenly go back down like drawing a "w" or an "m").

     

    You can think of the up and down wave a bit like drawing a circle. You can make the circle bigger, draw it faster, or jump the pencil across to a different part of the circle.

     

    Or you can do two or more of them at the same time (Quadrature Amplitude Modulation changes the amplitude and the phase at the same time, for a real headache)

  2. If you are looking at paint I can highly recommend Mike Starmer's books. I've got 3 out of 4 and they've been extremely useful and interesting. He has colour matched paint chips at the rear of each book so you can identify colour or get correct ones mixed up.

    Apparently there's a colour matched SCC15 available from The Vintage Paint Company, but they're not producing it at the moment (or weren't when I emailed). I've picked up some 381 olive drab from RR's warpaint range in the mean time.

     

    I know there's a lot of rivet counting on the paint side these days, and there would have been a fair bit of variation. That said, the british olive drab looks like a very different green to the more common NATO & US olive drab's. I think the British SCC15 olive drab is a much prettier colour, but that's personal choice (and I'm colourblind so I'm probably seeing it a completely different way to everyone else) :-\.

  3. Hi Paul,

    so that is what that tin is for, I have seen them and was always told they were grenade primer tins. Yes, please send an image of the packing material.

    Seems rather small for a bulb tin but I suppose if packed correctly it will work.

    Cheers,

    Dave

     

    I've got one of those as well (somewhere). I wondered what it was for!

  4. It's funny how tastes change - looking back at my choices from 2008 I'd probably go for completely different vehicles these days. Call me fickle.

     

    I especially like the idea of the "Securicor van, fully laden" from one of the earlier posts. :angel:

  5. Jack wasn't suposed to find out about the food fight :shake: It was all roxies fault

     

    It's a bit late for that, the barbecue is on the roof :rolleyes: with the GMC :shocked:

  6. First up, make sure these are really what you want - 1050R20 is a slightly different size to 1050-20. If you hadn't picked up on it, the R means the overall outside diameter is slightly smaller.

     

    Assuming you really want R's I have 5 Continental MPT 80 M+S tyres, with plenty of wear left (one spare looks brand new, the other four are only about 5mm off of new), all in very good nick (no cracking, they look almost new) on some 20" wheels. I'm just up the road from Cambridge.

     

    Drop me a PM and we'll talk pennies.

  7. I quick (very careful:sweat:) look on Wikipedia tells me a Butt is (amongst quite a range of other things :shocked:) a practice target for archery. Is that along the right lines?

     

    If so I still can't picture what they are up to.
