- Audio Delay time after TRX enters receiving mode: from 10 to 700 ms (variable)
- Attenuation of the antenna signal in receive mode when common antenna is used (TRX and SDR are connected to common antenna at the same time) :
- At TRX input: -2.5 dB
- At SDR input: –3.5 dB
- Delay of the ANT Switch relay after active transmit TRX PTT signal: 3 ms
- Delay of ANT Switch relay after receive TRX PTT signal: 5 ms
- Level at the input of the SDR when common antenna is used (transmit mode): < -30dBm
- 1 dB compression point of the limiter protection circuit: +8 dBm (peak value)
- Audio ground loop separation: yes
- Power -10 to 15 V DC, max. current: 55 mA (at 13.6 V without external optional relay)
- SWR during transmission: <1.2 (1.8 to 50 MHz).
- Additional external relay control for station automation: 12 V, max current 200 mA (energized in receive mode). Delays are the same as for the relay in the ANT Switch.
Protection parameters with common TRX / SDR antenna:
- Power supply over current resettable fuse
- Protection against TRX PTT cable disconnection
- Protection against ANT Switch control cable disconnection
- Protection against missing power supply
- Double fault protection of ANT Switch relay dysfunction
- Maximal continues input RF current of SDR protection limiter: 1 A
- Maximal peak input RF current of SDR protection limiter: 2 A (2 sec duration)
- Additional resistive fuse in fault mode
- Maximal output level of protection limiter: +12 dBm (2.5 V p-p value) @ 1 A RF current
