Works great through a Danmar 1200 Solid State amplifier.</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">For no reason the Tx audio is now suddenly being heard through the PC Speakers using Rx 1 but NOT when using Rx 2.</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">When I first set up the HPSDR using PowerSDR some of our group noted this audio would occur IF the mike lead braid was connected to the Atlas or Penelope/PenyLane ground. The braid was connected to the amplifier chassis.</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">I am using the latest avaiable PowerSDR software.</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">The Transmit is fine when using Rx 2. An interesting problem seeing as I have checked all wiring etc. <br></div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Any suggestions from the group. When I find the solution I will post on the forum.<br></div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Cheers Dean. VK5LB.<br></div></div></div></body></html>
