  1. Requires licence and still regulated, un-regulated cb used to occupy  frequencies around the 10m band. You could on 20w at night achieve long distances. The 27Mhz range is full of rc and regulated fm cb. The 10m band Is also one of the easiest frequencies to produce homebrew (user made) kit.

    One of the best frequencies for local c25Miles contact is 144Mhz, though with cross band repeating you can achieve distances. There are other methods to  achieve distance, but the geekdom goes up a notch! :grin: ..(trop-e, trans-p...)

  2. The advent of quality mobile phones on unlimited minutes and texts have just about killed it ! The skill in talking to someone on the other side of the world using a few watts erp is being lost.

    In order to accomplish the above, you would need each person to have completed basic license test, a couple of hundred quids worth of radio transceiver, aerial and cables. All on the same frequency, all operating within licence conditions :grin: ... Conference call on your mobile....

  3. @austinR, I think you would be surprised at how many astronomers used to be ham radio fanatics. E-mail, internet & instant messaging has just about killed off the amateur radio licensing. It used to be a very  extensive test and a cw test (basic ham license gained 1975, cw passed in 1983!)...

    Offshoot is using ham gear to detect meteorites :-- http://www.popastro.com/meteor/observingmeteors/radioobserving/index.php

    Ham radio pretty cheap now :grin: .

  4. @sirrah, they are also there to control access to the classifieds. The mods take a dim view of superfluous posts and they can be deleted. Whilst it is no guarantee of good advice if someone has a long standing presence on SGL then it is usually good advice. If it is not someone else will always contribute.
