Tonight I was able to capture the low-quality analog signal.įor this and most of my other experiments, I used TV rabbit ears. This was one of my considerations when I chose the SDRPlay, since the high-quality digital mode is 4 MHz wide. Just make it work the way you think it should on known-good data before you try feeding an unknown recording into it.I've been wanting to capture weather satellite signals for quite a while.

It looks like that particular software is designed for using an audio interface I'd try putting the stream data in a common format like 16-bit, signed, 48 kHz mono PCM (.wav) and see if that gets any results.Įdit: if you know 16-bit 11.025 kHz works, hey, sounds good. You may also need to massage the data a bit to get your software to accept it like you said, if wxtoimg can only read 16-bit samples you'll never make it happy by working on your antenna. Once you get something that works at least intermittently you can always come back and make it prettier.Ĩ bits means higher quantization noise, but I think it's plenty if you can get the SNR up through other means. There are also plenty of instructions out there for DIY RHC-polarized antennas, including some directional or band-specific ones which would cut down on intermodulation even without filtering.Ī simple bandpass filter is probably fine you just want to get the high-power broadcast radio and TV stations across town to stop desensitizing your receiver's front end. Are you twisting the antenna around to put the satellite in the plane normal to the antenna's vertical segment as it passes? Even if you do this you're losing up to half the signal just because your antenna polarization doesn't match that of the signal, and more if you aren't.Ī real, physical bandpass filter between your antenna and SDR dongle would likely do wonders for pulling the signal out from the noise at 137 MHz you can get in the right ballpark with just a few discrete RLC components, a soldering iron, and a couple of spare connectors. If so, how does the signal to noise ratio in those sample files compare to what you're getting? I'd suspect significant intermodulation products and a high noise floor on a discone antenna, not to mention multipath interference given its poor high-elevation pattern. In contrast, the Planar Disk is almost free and it performs quite well in an indoor setting.Īre you able to decode sample recordings from other sources? Just because an antenna "is sold" does not mean its good or even marginal. Please verify your dongle is working with a good antenna before complaining that you cannot receive something. Here is a great, broadband Planar Disk Antenna that outperforms most commercial antennas of similar size for under $65-75 and can be built in a half hour or less by beginners with less than $10 in parts. See our wiki with tutorials and other resources including a Quick Start page to verify your dongle works.
