Enormous wavelengths are very useful for penetrating rock (cave to surface - molephones) and
the oceans (for submarines) but the antennas need to be rather large, or magnetic loops.

They argue that little real harm is done on the unused civil aero channels, but a lot of
channels ARE used, especially between 6600 and 6635. Of the hundreds of stations active,
some do venture down as far as 6530 but "most don't really go below 6635" has been heard.

30-40 MHz allocated for private land mobile use in 1947
25-30 MHz and 44-50 MHz bands allocated for private land mobile use in 1949
20kHz channels were introduced in the 25-50 MHz band in 1957
Parts of 25-50 MHz allocated to Highway Maintenance, Police and Special Emergency Radio Services in 1960

Was 50 kHz spacing until SOLAS 1972, then new channels were fitted in, in between...
Band structure: two main sections linked by a 4.6MHz frequency shift
Dual channels : international and private
156.0-158.4 lines up with 160.6-163.0 at 4.6MHz higher, the lower section being the ship/mobile
side of dual-freq. channels, the higher side being for shore/base. The international channels
finish at 157.425/162.025 and the rest are private channels, which may be dual or single.
Single channels:
156.375-156.875 and 160.975-161.475 are not joined, and have single-freq usage with international
channels at 156 and private at 161.
160.9 used to be used for ITV talkback, I'm told.
Also used for talkback was 161.3875 (12.5 kHz),
and within the channels 161.325 and 161.45
The RA's own channel numbering is as follows:
Channel numbers 1440 (156) to 2000 (163.0) can be traced back (in
12.5kHz steps) to the start of a sequence where channel 1 is 138.0125
- this applies up to the last Mid-band channel M2163 (165.0375) and
down in the JRC bands i.e. M802 being the high side of the 148.01875
& 139.51875 pair, give or take a half channel offset (-6.25kHz) (as
happens positively at 448 / 431 ).
160.6 is RA channel 1808, 156 is channel 1440 - the difference of 368
being 4.6 MHz worth of 12.5 kHz channels. Marine dual pairs take the
channel number of the higher (shore) frequency. For single use of the
private section 157.45-163 the channels numbers are shifted along in
sequence by 1000.
Let's track this in two columns 4.6 MHz apart...

Many CBS (including some multi-channel trunked CBS) - 85 dual channels available.
Despite this section only being allocated to LAND MOBILE, (12.5 kHz) in some
books and magazines you may find extra marine channels given (channel number
greater than 50), either single or -4.6 dual, in the first 150kHz or so. (i.e. ch 53)
This seems to be a throwback to a bygone age when the marine band was larger.
Marine channels are 25kHz bandwidth too, so that ruins half of the 12.5kHz channel
above and below.
The first 70 per cent used to be used for the old BT RadioTelephones :

Early versions used from 163.0375 to only 164.2125 as System 4 channels 95 down to 01.
U57 (163.7375 - base only) was control. 163.025 and 164.425 were boundaries.
and before that:
163.050 ... BT System 3 (1977), to 164.400 (split -4.5, 25kHz channels 55-1 in reverse!
