I'm thinking of buying a communications receiver of 60s or 70s vintage, but I'm also considering constructing one as a project instead. Are any of the Electronics Australia designs worth building? I did once try making the EA 160, but it was awful, spurious signals all over the place.

Do it! It's a lot of fun https://www.youtube.com/watch?v=xqe1Y7SQX2k. A 50's domestic radio on shortwave should be able to tune 7.125 MHz Wednesday and Saturday mornings for "the AMers". They are a group that use old equipment that does not have any sideband modes. http://www.macnaughtonart.com/40am.htm. Later on you'll be able to tell who's transmitting on a radio with a valve output section no matter what you're listening on. I'd recommend looking for something that will do from AM broadcast through to 30MHz with sideband modes.
