Thomas Scherrer OZ2CPU UHF RC system version 3, LRS, long range, OLD VERSIONS
OLD VERSIONS INFORMATION
Transmitter board inside the case, version 3.32
The transmitter board is 45x68mm.
Possibility for more output power:
Safety ! fly using the low power setting, and in case loss of signal activate the powerup feature
The unit is shipped with a 3 way switch so the user can fast and easy change the level while flying
0.5W / 1W / 2W power out, the 2W setting is ONLY for short time rescue opperations
RF Power output: 0.5W or 1W or 2W use selectable
Supply Voltage : 6-25V using internal switchmode converter
Supply current : depends on input voltage, input supply power is 3-4 times of RF output power
Spurs : 40dB under carrier
Temperature range: -40C to +70C tested

The new PRO version
WARNING FUTABA owners must read post 1573-1574
Receiver 3.00 and 3.10 (old version, sold out now)
The receiver board is 45 x 54mm, weight: 12 gr.
Receiver with DIVERSITY ! and LNA Low Noise Amplifier, uptimized input filter so it can co-exist with strong 2.4Ghz on board video transmitters.
Two MCX connector coax dipole wire antennas come with each RX this type.
Sensitivity: -112dBm
Input voltage range: 4-6V
Servo signal pulse output: 3.3V positive
Radio band: 433 & 444Mhz multi band and multi frequency hopping system.
Temperature range: -40C to +70C tested
Price 100 $ as long as stocked.
Receiver 3.31 LR Long Range Diversity (sold out)
The receiver board is 40 x 54mm, weight: 12.7 gr.
Receiver 12ch with DIVERSITY ! and LNA Low Noise Amplifier, uptimized input filter so it can co-exist with strong 2.4Ghz on board video transmitters.
Two MCX connector coax dipole wire antennas come with each RX this type, weight 5.4 gr each
the extra pin in ch 12 connector is rssi out, ch 12 connector is also ppm out when < 12ch are used
PPM out is the same as sum-signal and this is offcourse fully compatible with mikrocopter controller board, all RX have this.
Servo pins how to connect explained see this so you connect it all right.
Sensitivity: -112dBm
Input voltage range: 4-6V
