As I have said many times before, if I had to give up every other amateur radio magazine I would leave GQRP SPRAT. At £6 for 4 issues a year it remains excellent. It is filled with constructional articles in every issue. If you are a member you can get all the back issues on a DVD at a very good price. It is almost worth joining GQRP just to buy this DVD. To non-members it is £12 plus postage. I can promise you will not be disappointed with GQRP Club membership.
