Unusual relay behaviour with HL2 piHPSDR & 2 RX's #169

I have successfully installed the latest release of PHPSHR on LinuxMint running on my HP Laptop its working great and seems rock solid. However I have observed quite odd behaviour regarding the relays when keying the radio to TX. I have two receivers running one tuned for 20M the other 40M, 20M is RX0 and 40M is RX1. Both receive perfectly sample rate is set at 4800 and both set to mute when not active. When I TX on RX0 currently set to 20M my Hermes Lite relay clicks once and immediately goes into TX state however, when I TX on RX1 their are two relay clicks and a few milliseconds delay before TX actually starts. I initially suspected a filter setting issue relating to the band however if I set RX0 to 40M the problem disappears, It affects RX1 regardless of the band selected.

Is there a setting or configuration somewhere I have missed or is this expected behaviour?
