It seems like 915Mhz Sik radios are all sold out and it seems no one plans to restock (I need a bunch). Aside from the ESP8266 / 2.4Ghz Wifi, what is a cheap alternative to the SiK radios that would be great for a backup to the WiFi? I was looking at perhaps the 900Mhz Xbee, but it seems like those are frowned upon. I wouldn’t want to crowed the Wifi range with an Xbee 3 (runs in the 2Ghz range). Thoughts?
Mro has them. With telemetry on the Transmitter with all models I use the ESP8266 radios for all else (configuration, calibration).
I understand your concern with the 2.4GHz band, but a couple of us have had some interesting successes using the proprietary ESP-Now feature of ESP8266 and ESP32 boards and external antennas. If you’re truly on a tight budget it’s worth a look. Otherwise, I’m with @dkemxr - go with mRo.
Oh, I’m totally down with ESP wifi - I have it already. The Now stuff is interesting. I was just looking for redundancy. I’ll check out MRo! Thanks for the tip.

Either of you use this Scisky Mini Radio before? Seems to support Sik firmware.
Never heard of it. I’d be a little concerned about the built in antenna.

Hobbyking used to sell those and I recall some using them on small craft. But I don’t remember what the performance was like. I would agree with Yuri that the range can’t be great.
There’s testing underway for an update to the sik hardware (si1000 being eol), using si1060. Branch is in GitHub.

Hi,
Is there a Multi-Point version available too?
I can’t find anything…
