Volume level adjustment for Niftymitter 0.25?

Tester Andrew has been busy with niftymitter 0.24, as reported earlier. He has now put up a thorough post on his blog, discussing some of the early issues he is having. To paraphrase, he wishes particularly for a means of adjusting the line input level, as well an AM version of the transmitter, and a similarly designed radio receiver. I am very much in favour of all of these – the level adjustment seems an obvious oversight now, and I think a sister radio reciever for Niftymitter would be both elegant and an interesting development for new applications. Mike Shorter in Dundee mentioned this early on as a means of relaying a transmission across a longer distance..
