A point missed about programable commercial radio equipment is that
this was allowed as an "experiment" by the FCC and approval for their
manufacture was recinded after a short trial use
period. Non-technically trained operators could and did program
their radios to operate on top of licensed services such as public
safety with severe results.
Lets define programable while were at this. It does not mean a radio
that can be changed in frequency to predetermined
frequencies. Marine (part-80) radios are pre-programmed with a
standard set of channels established for the marine
community. Aviation radios can dial in any frequency in 5-KHz steps
within the aviation band. But both of these services have been set
up by the "authorities" governing them to use certain frequencies
within a reserved sub-band.
A programable radio can be set to any frequency that the radio can
operate. Commercial Hi-band VHF: 150-174 MHz.
