Hi everyone, I have an Icom F80S portable. I am having a problem getting certain channels to take the programmed frequencies, and I am unsure if it is due to being out of frequency range, being a narrowband split, or if i have selected the incorrect polarity for DCS. Channel information will flash on and off on the display, and I a do not recieve anything on those channels. Is this simply a matter of a firmware upgrade? I can read the radio with the software if you need more info to provide an answer / educated guess. Much appreciated, thanks!
