Many Geohashers have expressed concerns over how to communicate with other Geohashers when approaching a hashpoint location that is potentially inaccessible. In the event that this is the case, it is recommended that Geohashers in the vicinity of a hashpoint use the following two-way radio frequencies to communicate alternative locations for meetups:

Region	Radio Channel	Frequency
North America	FRS/GMRS Channel 6	462.68750 MHz
	Amateur Radio	146.52000 MHz
Europe	PMR446 Channel 6	446.06875 MHz
	Amateur Radio	145.50000 MHz. Change channel after making contact.
Australia/New Zealand	UHF CB Channel 26	477.05000 MHz
Japan	SLPR F3E simplex channel 12	422.20000 MHz

Amateur radio

Geohashing is a good opportunity to use your mobile rig.

If you have an amateur radio licence, putting the Callsign template on your user page will mean you will be included in the automatically-generated list of radio amateurs, and other geohashers will know who you are!

APRS

In recent years, the Automatic Packet Reporting System (APRS) has emerged as a way to share local information of immediate value in real time. This information is often the position of its users, but can also include short messages and announcements, telemetry data like weather reports and storm forecasts. The set of radio amateurs who are also geohashers might be countable on one hand, but it nevertheless seems like a good (if excessively-engineered) way to coordinate an expedition. The hashpoint can be temporarily advertised as an object of interest, with accompanying link. Geohashers who aren't radio amateurs can also play along by viewing the current situation on aprs.fi.
