"I'm no longer working with that project and I didn't check the range with two SRH-771s. Winter came, waters froze. :)"

" Did you have to do some kind of fault checking code because there were two devices on i2c bus?"

kopo replied to Mike Mac's discussion How do I convert rssi to % signal strength?
"Maybe you also need noise amount to calculate signal strength percent. Just guessing."

"Hi,

I have stock antennas that came with radios. Radios were bought from 3DR so i Think these should be for 433 MHz (Blue dots). I'm going to buy two SRH-771 antennas and see what happens."

"I have not tested the radios with full power since it's against regulations. I got my hands on one SRH771 antenna. it's 40 cm long, 2,15 dBi. I put the antenna on the water rower and my range increased from 100 m to over 250 m.
It is good…"

"What do you mean by cutting parameters? Send less parameters or adjust telemetry settings?"

"Can anyone help? it doesn't matter if I set power level to 8 or 14 dBm. I still get about the same range. My "rover" is device that moves on water surface. Antenna is about 15 cm above water."

Hi,I'm using 3DR 433 MHz telemetry radio. Transmit power is set to 14 dBm 25 mW duty cycle is 10%. These are max settings in my country. I'm using stock blue dotted antennas. How much range should i expect?I'm getting little bit over 100 m range…

Hi,I'm using APM 2.6 to steer and navigate a device that moves on water. I wan't to install several serial or analog water quality sensors. Can I use APM 2.6 to read several serial sensors and for example log sensor data to telemetry log?Would it be…

kopo replied to Rigel's discussion Waypoints read and write communication problem between APM 1.1.85 and ArduPlane 2.34
"In my case I had to double airspeed. Apparently there was timeout problems. My duty cycle is 10 %, so it slows down communication enough to timeouts occur."

Hi I'm building my vehicle using APM2.6 and using some high voltage servos 6/7,4V. It is stated that "OUTPUTS" voltage should be under 6V (ABS MAX) is it so even when JP1 is removed? And another thing. I wondered why my digital high voltage servo…
