FPP is a misnomer on most radios in that it allows you to modify a channel, NOT create a new one from whole cloth. I create a zone of dummy channels (FM, P25 or mixed mode) which I can use FPP to set frequencies, tones, NAC and maybe TG (not sure about TG). Like you I very very rarely use them in the field. I mostly use FPP due to original channel being incorrectly programmed (I know…test codeplug!). if i could run cps on my phone it would be great (wifi or BT programming). some guys have tablet pc small and light enough to at least put in their daypack.
