Karol N commented on Jake Stew's blog post 915 MHz 3DR Radio Tuning With $7 SDR Spectrum Analyzer! Spectacular range boost!?
"I think it's 434MHz modulated with 600Hz, but as in my post from Friday it doesn't work like that in my case.Pulsed signal is IMHO like normal operation FHSS - some precomputed pattern, between max an min frequency."

"I used realterm. Params: 57600 8N1. First input +++ without any line endings, and after OK reply use AT commands with Windows line ending (CR LF)"

"Hey folksI have a lot of trouble with my telemetry (range below 100m), so I checked my modems with Jake's firmware. I used commands: +++, ATJ, ATK, ATK, ATK. Every time it transmits on completly different frequency, where as far as I understand, it…"

Karol N commented on Euan Ramsay's blog post Autotune:0...Ground:2
"It might be temperature issue - I suppose it was cold, if you brig your copters from warm place (home or car) and almost limitedly started temperature drift of IMU may change at unmanageable rate, and crash the copter. Also some ESC (cristalless) …"

Karol N commented on John C.'s blog post Scripted Fixed-Wing Acrobatics
"Hi, I have done some experiments with this on my project. About 1. point try to send RC override message with value 0, this should bring you back to control, but this is still problem when you want interrupt scripted manoeuvre, or when telemetry…"
