I have one of each of the following issues of the RSGB collected Technical Topics columns by Pat Hawker G3VA. These are A4 size and weigh about 1kg each.
They’re available to anyone if you pay for the postage (in the UK that will be £3.80 each). I’ll post anywhere if you are prepared to pay the postage!
If you are interested, PM me here. I’ll wait till next Tuesday and pick some names (assuming people are interested) at random and contact you.
