A labeling machine. A punk song will go on the radio loved by posers for a short time then go off known as "old" or "pop" forever more.
random that listens to the radio: Did you hear that (insert once good song here) on 92.9?
other random that listens to the radio: Like oh my god! That is so old! That new pussycat dolls song is way better and fresh.
me: *adds randoms and 92.9 to "to shoot" list*

Term used in the Los Angeles County Jail to tell inmates to shut up so the Deputy can hear his police radio while walking on the row. Usually "radio" will be yelled by a shot caller in the module or a trustee. If the tier or row is too loud and the deputy gets pissed off, there is a high probability that the duputy will shut off the phones, search cells, or find other ways to cause suffering to the inmates.
"Hey baker row. Radio!! Deputy walking front to back!"

There are many different types of radio receiving circuits:
-Crystal (see above)
-Regenerative
-Tuned Radio Frequency (TRF)
-Superheterodyne
Modern radios are superheterodyne. The superheterodyne circuit replaced the TRF and regenerative circuits by the 1930's, and crystal sets were nearly dead until solid state radio emerged.
