Seppo replied to Aussie in AZ's discussion 3DR telemetry no longer supported by 3DR....options?
"Hi,
I don't see modems in the 900MHz band becoming obsolete at all.  The frequency band is available in a large number of countries with pretty good license conditions (1W in Aus, and 4W EIRP) in the USA being available.  The propagation in the 900M…"

Sorry to hear you are having some trouble!... - How did your visit to the repair shop go?, were they able to confirm the setup was OK?

Firstly, if a modem has a red-led by itself, the modem does need to be re-programmed.  This happens on a…"
