Twelve channels.

Eleven TV channels are in the VHF spectrum. My count is 12 in the USA (2 -13).
The uniden smh 400d has 36 channels
There are 12 channels. They are channel 2 through channel 13.

VHF is the more common for tv channels, you are probably thinking UHF
There is a possibility of 12 but you will never find all the channels filled even in large markets. Cable is the exception.
The VHF channels go from 2 to 13, so there are 12 of them. So, 19 + 12 = 31.
Sets with only VHF tuners had 12, Channels 2 thru 13. In the later 60s a UHF tuner was added giving the set channels 14 thru 69 and some sets had even higher channels.
of course its 12 channels...it's obvious!
