Hello,
The Es season is starting again 6m/4m and I checked the RX performance of my Sun SDR2Pro. (software & Firmware from 1.3.0 Beta 1)

On 6m I use A2 signal path for Tx and A3 input from LNA - if needed.
Antennae settings can be programmed and stored as they should be. - All OK!
In this case (6m) it DOES NOT matter how the VHF Antenna socket (A1) is configured (I use A1 for Txpath and ADC input for RX routimg the signal through a separate 2m BP filter)

When I switch to 4m (Gen - ) apparently the setting of the A1 Antenna (VHF) terminal effects the signal path for the Gen (4m) reception, which SHOULD NOT happen.
To oparate as on 6m, I need to set A1 Function to A1-A1 else the A2 Antenna input for 4m Band Rx is also disabled.

I guess there is an easy way around - but I don not want to try modding the config files due to my lack of information.
