Programming the CP100:

Programming the IC-F11:
I believe one must purchase software and a programming cable to program the frequencies of this radio.

Not sure what you want.....VHF band ius approximatly 130mhz to 175 mhz..... in that VHF band there is a commercial VHF band aprox. 155 mhz to 175...... the amateur radio vhf band is aprox. 135 to 150mhz.

 

With amateur radio, any freq in that range can be used...... with commercial radio the FCC cangive a company any freq. in that range also.

 

If you are looking for FRS/GMRS frequencies they are UHF freqs not VHF.

So I'm not sure exactly what you want......sounds like you might want to program in FRS freqs into an Icom amateur radio. If thats  the case you will need an Icom that will do UHF freqs.
