Re: Don't forget
Here in GB, the Amateur Radio licence was (is?) granted for the purpose of 'self-training in wireless telegraphy'. Us engineering bods had much fun making antennas, receivers and transmitters and test equipment. So much more fun than buying commercial gear. I was into packet radio, and spent my time converting commercial radios for use at VHF/UHF nodes, and building TNCs for myself and others. Great bunch of people, all sorts of trades, ages and attitudes.
Things have got simpler now. Decent, simple hand-held transceivers can be bought for peanuts, with and without the 'digital' stuff. You can also buy all singing, all dancing HF multimode radios for big money if you want (I know one guy with a radio costing in excess of GBP10k!). Most stuff these days is computer controllable, with some of the serious 'contest' stations relying heavily on automation.
Fascinating hobby, bloody good training in a range of disciplines, plus great people, usually..
I am a G7, and the only spectrum I am on is 2M and above:-) You can keep the HF 'DC' stuff and the associated humongous antennas!
