SARA’s 442.275 repeater is linked by default to reflector XRF330C , which is SARA’s reflector. If you have a hotspot that is up and working, you can configure it to connect to this same reflector, and be able to talk to people on the 442.275 repeater from anywhere.
In your radio’s programming software, set up a channel with URCALL (Your) as XRF330CL on your hotspot frequency (use your own call B and G in RPT1 and RPT2).
Once this is loaded on your radio, key up once on your new channel, then switch to your CQCQCQ channel. You’ll be connected to the SARA reflector.
