If you like radio in any guise you will love the hamfest days out!
Loads of junk and stuff. I came across an FM exciter tx with home brew 35
watt PA for £5
If there is any gear there the hams ain't interested so it's usually cheap!
Plus in the UK, in theory any court/ RA/ seized gear, is sold to hams for
dismantling and experimental use at such events, worth keeping an eye out.
