    "content": "I did some experimentation with the $20 dongle vs the FunCube dongle for \nreceiving weather satellites.\n\nIf you live in an RF dense area, like here in Southern California, they \nBOTH benefit from having some front-end filtering added.\n\nOther wise you have to turn the RF gain down quite a bit on both of them \nto prevent 'break through' from strong signals that can be may MHz away \nfrom your band of interest.\n\nIn my case, I used an SSB Electronik 2 Meter preamp with an old M2 2 \nMeter Eggbeater antenna. I could get reasonable copy above 10*~15* \nelevation with just the dongle and antenna, but suffered from strong \nsignal break through. If I turned the RF gain down to where the \ninterfering signals no longer broke through, it cut my reception down to \nmaybe 25*~30* elevation.\n\nWith the SSB preamp and it's built-in helical filter, even operating at \n137 MHz, the difference was staggering, and I could get good copy down \nto 5* or so.\n\nThe only other SDR I played with for a while was the HackRF, which I \nfound to be unsuitable for what I was looking for. Despite the hype \nbehind it, it's still an 8-bit unit with limited dynamic range.\n\nYMMV!\n\n73, Jim  KQ6EA\n\nOn 06/16/2016 08:33 PM, Peter Laws wrote:\n> On Thu, Jun 16, 2016 at 3:22 PM, Patrick STODDARD (WD9EWK/VA7EWK)\n> <[email protected]> wrote:\n>> Unfortunately there isn't anything in the middle ground between these\n>> dongles and devices like the\n>\n> The $20 versions are well worth the effort if you've never played with\n> an SDR of any sort before.
