If I had my satellite station in a proper ham\nshack, where the radios are inside and antennas are outside (or\nthe antennas are not within a few feet or a couple of meters of\nthe radios), it is possible that the house or building may be enough\nto keep the transmitter from affecting the RTL-SDR dongles.\nI don't have that option for working satellites, even when I am at\nhome. My antenna is always within a few feet or a couple of meters\nof my radios, both transmit and receive. Putting the dongle in\na case with some shielding, and maybe adding some filters in front\nof the dongle, could make that work in my situation. Between the\ntime and money needed to do that, I think I'm doing fine when I use\na FUNcube Dongle Pro+ or SDRplay. In fact, whenever I move to a place\nwhere I can install a proper satellite station in the house,\nwith antennas outside and the radios inside, I know my existing\nSDR receivers (FUNcube Dongle Pro+ and SDRplay) should work fine\nin that environment as they have when I've worked portable.\n\n73!\n\n\n\n\n\nPatrick WD9EWK/VA7EWK\nhttp://www.wd9ewk.net/\nTwitter: @WD9EWK\n\n\n\nOn Thu, Jun 16, 2016 at 11:08 PM, Eduardo PY2RN <[email protected]> wrote:\n\n> The cheap RTL dongles are as much sensible (or more) than the others more\n> expensive.Lack of filtering is the big issue although there are some\n> practical and easy workarounds to improve it.For ham satellites downlink\n> frequency stability should not be an big issue, there are some models\n> already been sold with 0.5PPM TCXO option which are still cheap.It is a\n> great opportunity to operate full-duplex on amateur satellites with very\n> low investment and improving operational capabilities.\n> EME (Moon bounce) audible signal RX comparison between TS-2000 / RTL /\n> FunCube Pro+ can be seen here:\n> https://youtu.be/3OxyO5ylwfs\n>\n> 73\n> ED PY2RN\n>\n", "attachments": [] }
