Ha - I wasn't far behind you. I saw you buy the 6058
. See tggzzz's comment elsewhere. Thanks for leaving the HP!
I think Wood Green was actually the Cambridge radio club, CDARC. There's a lot of cross-fertilization but CDARC rally used to be in Addenbrooke's Ambulance Station in winter and held one or two in a barn near the Mullard telescope. I don't think they still have a rally though I'd be happ[y to hear if they do.
The Repeater group (who run the amateur repeaters at Barkway tower) used to hold their rally in the Pye (later Philips) car park. There may have been another location before they settled at Foxton, I don't recall.
