Default Re: Save our 2 Metre Band.

I don't think the coming of CTCSS/12.5KHz made much difference. 12.5KHz spacing has been the standard for PMR stuff for at least 40 years, and CTCSS was ubiquitous there too (along with 5-tone selcall) so your generic 'surplus' Pye/Motorola ex-utility-company/taxi-radio was ready-to-go with a suitable EPROM (and lots cheaper than buying stacks of crystals like we had to do in the old Westminster/Vanguard days!).

I think 2M died just because the world moved on. Same as for VHF/UHF PMR (emergency-services, the local vets, courier- and taxi-companies all now gone digital) and 11M CB.

Cheap, ubiquitous cellphones and digital data have a lot to answer for.
