Literally no one asked, but it is very important for me that you know that:
the WKIL station broadcasts in DRM (wikipedia link for more information);
most killjoys try to keep both a digital and an analog radio of some sort of them even if it's just a dashboard radio or a handheld;
the WKIL station has secondary set-up with an analog-to-digital system they use to receive calls from listeners that Newsie threatened to go on several rampages over, and Pony and Cherri both seconded that decision for having to play dispatch after its completion;
there's a few books on transistor radios going around the Zones, and whenever someone needs it they leave their contact info on Dr. Death-Defying's radio segment or in a zine, alongside a time when they'll be expecting an answer on the provided frequency;
calling anywhere other than WKIL is one of the most annoying feats known to humankind, and even on WKIL you'll sound like you're inside a washing machine while speaking, but beggars can't be choosers;
there are ghost stations out in the Zones! Impossible stations that play recorded clips of 'joys that tried to disturb the on-going transmission of white noise, and number stations BL/I gave up on trying to locate and left run out;
parabolic dishes and various radio broadcasting equipment is often left at the broadcasting site of said ghost stations to both provide coverage Zone-wide (or at least in the eastern and north-eastern areas) and conceal them from BL/I's satellites by playing a bunch of extra junk.
