HamRing Selective Calling App |
Introducing
HamRing, the new app for HF Selective Calling
(Selcall). Use it to call your ham friends, and it
quietly monitors your radio frequency for an incoming call.
It works with any HF SSB transceiver or VHF-UHF FM
transceiver.  HamRing enables operators to call each other on the air. Add your favorite callsigns and selcall numbers to the directory. Send a test beacon or a selcall. HamRing sends a beep response and alerts the other operator of the incoming call. A HamRing selcall doesn't use the internet; it uses your radio transceiver on a frequency you select.  How Can I Get HamRing? HamRing is currently under development. It is not yet available for download. A beta version of HamRing is planned for release in mid to late 2019. |
|
| An experimental
version of HamRing was tested in November 2018, with good
success. |
