Default Programming a frequency

I'm wanting to know why my VHF ic-f3gs wont let me program the frequency 154.2575? Does anyone know the answer or have any tricks to get it to work?

When you type in the frequency, do you also select N under mode? That frequency is part of the new frequency assignments and should able to be installed in the radio.

Also, are you using the correct version of software?

Weirdness. Playing with my version of the latest SW, I can get it to accept some narrow channels, and not others. It looks like only every 5th narrow channel will work.V2.2 was the last software release, copyright 2001, before the 'Plan' was really a plan.


Sorry to say this, but the F3's are getting long in the tooth. Ebay it to an amature and move on.


Knowledge Base Article 74IC354553

Issue: F3G / F4G Wide or Narrow - How can I tell if my F3G or F4G is wideband or narrowband?

Resolution: F3G Model numbers 86 and 87 are switchable for wide and narrow; F4G model number 90 is switchable for wide and narrow. All other models are narrowband only. If you don't know the model number of your radio, Service dealers can see it on the PCB when you remove the option cover.

I got rid of my F30GS for the same thing - it would not program two of the VTAC channels. Some of the "splinter" frequencies are not in the firmware and there is nothing to do but get something newer if you need them. A lot of older public safety type radios will do narrowband (which is transmitting only half the audio level) like the HT1000 Motorola for example, but won't program the 0.0025 steps for some of the new frequencies. I see a lot of web posts where someone purchased a ham radio that can do the narrowband audio, but only programs 5 khz steps. They can't get the radio on the new Part 90 splinter freqs and are upset because it was sold as a narrowband capable radio.

A radio does not have to do .0025 channel steps to be narrow band complint.

Narrow band compliant means that the radio has the ablity to have the MODE of WHAT EVER frequency it is programed too, to be set to 12.5kz spacing FOR THAT FREQUENCY.
