      Hi,

      A few more questions about NetSDR:
      -Does NetSDR still need a server computer to run with SDR-Radio client software?
      -Is there a provision (planned) on NetSDR to use seperate antennas for VHF downconverter and HF?
      -Is a provision planned to switch 2 HF antennas without server computer and Velleman VM110?
      -Trying out the online NetSDRs: Why is the NetSDR significantly lower in RF levels than the SDR-IQ, will this be evened out/calibrated in software?

      The NetSDR is accessed via the LAN from the client, no server in sight. Antennas - yes, I think so when an internal downconverter is used, Pieter will confirm.

        Again Pieter will confirm this.

        The software supports calibration, maybe you’re running with lower RF gain? Anyway calibration will be added if not there yet or just not yet good enough.

          Paul,

          1. The SDR-Radio client connects directly to the radio over the intranet. If you are going to use it over a slow connection or the internet, you will need the server.

          2.The internal downconverter slot uses the same connector so a diplexer would have to be used if you want separate ports.

          3. Maybe. There is a spare RF BNC that could be made to switch between two ports. There are also some surprises coming on this topic.

          4. The gain in the SDR-IQ is adjustable by changing the IF gain. In real life, it is not much different to the SDR-IQ. SDR-Radio should adjust the offset so that 0dBm at the RFport
          is shown as 0dB in the software (plus or minus FFT ripple).

            Hi Paul, all,

            I have a 'work in progress' write up of the Net-SDR on-line at http://www.uhf-satcom.com/sdr-netsdr/

            The SDR certainly is low noise, and has excellent minimum discernible signal characteristics.

            regards,

            Paul M0EYT.
