I've held off acquiring one- so far. In a way, it's fortunate that good 'uns get more and more rare and expensive... Amongst a breed (military radios) that have utilitarian (read "ugly") looks, it's perhaps one of the better lookers, that half-sector dial combines appearance and practicality in the way that Ekcos do. I know nothing about the things in detail but I'd heard that the DF circuitry was both innovative and effective, it seems a shame that there was such a widespread tendency to strip it out.
I like its US counterpart, the BC348, maybe one of the dourest looking radios ever, with front panel layout firmly in the "apply by blunderbuss" school of ergonomics but a revelation inside- beautifully and precisely constructed with a cast and machined alloy chassis. It strikes me as an excellent example of how the US were the masters of precision mass-production.
