Radio Society of Greater Bixby

Last year at Green Country, I thought there were a lot of books, old Radio Amateur’s Handbooks and Callbooks etc. This year I noticed quite a few Kenwood 520 HF rigs (plain 5 band 520, the 6 b 520S, and economy model 520SE without 12V capability and lacking plugs for the 10 Watt 6M or 2M trans verters. The one above is 6 band 520 SE with matching tuner and speaker. You’ll never find the two transverters (bc they didn’t make very many). No price on this one. The others varied up to $250, but you’d probably get the one from Earl WB5UUW for a hundred or less. Estate sale, and no condition stated. I did see one Kenw 820, the eight hundred dollar expensive alternative, worth it at the time bc it was single conversion (to 9 Mc) versus double conversion (600 kc wide at 9, and then crystal filter at 3395) which made the 820 noticeably quieter on 10M (without so much conversion/mixing noise).

A Yaesu 101B was there also, same vintage as the 520 but with Sweep Tubes in the final, an 11M band, and AM mode available (only one reason for that – CB). Sweep tubes bring the plate out through the pins on the base, so there’s a little capacitance there which reduces gain on 10M – less of a problem on the Kenwoods bc they use S-2001 tubes (like the 6146A) with a plate cap that makes them usable up through 2M freqs. It was marked $100 and the LandLiner phone patch another $50.
