Well,
ran into a major road block with my SDR-play, I went to try and use it on 50MHz during October when doing some EME contacts. Connected it to a real antenna and all I see across the entire band (below 49.5 to 51 Mhz) is the local 50.315 beacon (yagi not pointed at the beacon). Noise floor shows as being lifted by 10db from key off to key on of beacon and a comb of products across the active part of 6, which makes the SDR worse that useless at my home for 50 MHz use.
Not sure if others have experienced any strong signal effects with theirs but now not so sure this was a good choice as my Hermes board (ANAN-10) showed no sign of problems and the el-cheapo RTL dongle is not impacted in this way.
