Hi Leon, thanks for asking, but I haven't heard anything back as yet.
I fitted an $8.00 supercheap aerial for now, just to have an Air Chief radio that works. I also wanted to check that it did work after getting it repaired. It works just fine, great tone and all.
I'll fit the Air Chief aerial back into the FC when I get a cable with a threaded loose nut that fits.
I also bought another aerial with cable (already connected as one piece) at a VIC Swap Meet on Sunday. After Tony G bought a couple, I figured they must be OK for an FC.
cheers Kevin
