Simplex
National calling frequencies and what you can do without a repeater.
It's easy to make use of D-STAR without any repeaters or hotspots—as long as your MY call sign is set. Start by setting your radio for 145.6700 (the National 2m D-STAR Calling Frequency) and put your radio into DV mode. Just key the mic and you're operating with D-STAR!
Here are a few other frequencies to try:
| 2m | 70cm |
|---|---|
| 145.6000 DV | 441.0000 DV |
| 145.6700 DV (Calling) | 445.6700 DV |
HF from 6-80 Meters — see the HF DV notes on the reflectors & nets guide.
D-STAR simplex operation allows you to:
- Send your callsign with every transmission (though it's still advisable to ID via digital voice)
- Send your location if GPS is enabled, or the GPS coordinates are programmed into your base station (great for pointing directional antennas)
- Sending pictures via mobile devices or transferred to a supporting radio via memory card (you can even talk while you transmit)
- Send short text messages along with each transmission, as well as host text chats using the RS-MS1A or RS-MS1I apps.
With a supported radio and these apps, one can unlock some really neat features like Text Messaging chats.
