IMHO you should follow the rules for frequency of ID. It doesn't matter how remote you are.
on the other hand, IMHO on our trail runs station identification is often way over used.
(a) Each amateur station, except a space station or telecommand station, must transmit its assigned call sign on its transmitting channel at the end of each communication, and at least every 10 minutes during a communication, for the purpose of clearly making the source of the transmissions from the station known to those receiving the transmissions. No station may transmit unidentified communications or signals, or transmit as the station call sign, any call sign not authorized to the station.
See you on the trail
