Just a quick note to capture some thoughts on a possible use for SDR. This was spawned by a lament I came across on G4ILO’s blog today viz using WSPR for testing antennas and doing comparisons. Just wondering out loud (and please forgive me the raw nature of this) if an SDR radio along with an antenna, computer and network connection standing alone and isolated from your other LAN devices could be made to function with a VPN as an antenna test range? I envision you at your desk able to connect to my radio and desktop via VPN and thusly manipulate my radio such that it can be tuned toward your signal for as long as the connection is up. A/B/C yourself into oblivion and over many days, times of day etc etc. Ive always drooled over the display’s that show signal strength in DBm a la Flex 3000 et al. So there you sit watching the same bandwidth from 1, 2 or 3 thousand miles away or perhaps in the next village say, 1000 wavelengths distant able to A/B with measured results. I admit I have not paid much attention to SDR and this may be off table for any number of reasons but I often forget unless I write things down and perhaps someone more knowledgeable than I can shoot holes in it or offer up suggestions to improve the thought.
Thanks for reading my Blog. Best, Chas W5PG
