[TenTec] Orion 2 Rx ant socket

[G3RXP]

Hello Members,

I have a rx antenna for 160/80 metres so I have the Rx button pressed in, and while using it on 80 metres everything works OK, but when I go to 160, there is a loud hissing noise from the loudspeaker and the O2 reboots. It sounds as though there is a high level of RF coming into the rig via the RX antenna, I thought the rx antenna socket went down to earth on transmit.  Any advice appreciated.
