When I can't find anyone sensible to talk to I monitor 121.5. It's all very well London Information knowing about you, but what can they do for you? If you have an emergency it can take quite a while for you to fit a word in edge-ways with London Info, and the only position information they have to go on is what you've told them. Where as with London D+D, you've more or less got the frequency to yourself and they know where you are as soon as you push that PPT button. Besides, there's sometimes some interesting stuff going on!
What we really need is LARS covering the whole country and open all the time, but that's not going to happen. Perhaps we could have unmonitored frequencies for areas where we can announce where we are, similar to UNICOM in the states, but we're already running out of frequencies and also that system doesn't work too well around MATZs at weekends when no-one's there.
Perhaps the best solution is for everyone to transmit and receive ADS-B information, but that'll be a few years off yet, I think.
