Hi
I was willing to add a power amp for tx and LNA for rx with one single antenna in order to work qrp (or qro, hi!) with HPSDR.
I think we then need to have the "tx state signal" available on a pin in order to use it to control the relays.
What is currently encoded? (if it is...)
Thanks

- input for RX1 is connected to IN1
- inputs for RX2 and RX3 are connected to IN2
- output for TX is connected to OUT1
- output for a RX/TX switch control (PTT-out) is connected to pin DIO0_P of the extension connector E1
- output for a pre-amplifier/attenuator control is connected to pin DIO1_P of the extension connector E1 (this pin is controlled by the first ATT combo-box)
- inputs for PTT, DASH and DOT are connected to the pins DIO0_N, DIO1_N and DIO2_N of the extension connector E1
