Remote SDR# connection to Ham-It-Up HF Converter using RTL-SDR/TCP - Receiver is Deaf

Happy New Year to Everyone .... I am thinking this may be more of an issue with rtl_tcp than with the client software (SDR#) so I thought I would throw this out there and see if anyone has any ideas. I have a Ham-it-Up up converter connected to an EZcap 668 (e4000) dongle and am using a random length long wire antenna all connected on a remote linux server (with minimal OS install) where I am running rtl_tcp. I am starting rtl_tcp using the following command: rtl_tcp -a 192.168.110.220 -p 1236 -d 2 When I connect to the remote dongle/converter using SDRSharp with RTL-USB/TCP I get nothing but static / noise. If I put the converter in bypass mode, then SDRSharp and my dongle perform with the typical performance I have experienced in the past. If I move the same dongle and up converter combo to the same pc running SDRSharp and connect to the dongle using RTL-SDR/USB I am able to receive many HF signals, as one would expect. For example, CHU Canada, WWV, some local CB radio chatter and even our local airport's LF beacon at 329 KHZ. I also tried starting rtl_tcp with the -g option and setting a gain to try to match the gain options available under RTL-SDR/USB but that had no effect. I am just wondering if I am not finding the correct settings so this will work or if this is an issue with rtl_tcp? BTW: I actually have two other Ezcap 668's running simultaneously on the remote linux server as device 0 / port 1234 and device 1 / port 1235 working just fine when connected to other remote instances of SDR Sharp. 73's - Dave KD9GN
