Hi! How can you go to such low frequencies with RTL-SDR
?
Hi, you need something called an “upconverter”. It goes in between your antenna and SDR dongle. I bought the “Ham It Up Upconverter” from Nooelec.com.
Thank you! I will look for it! You can check out my latest video, where I download NOAA satellite images with rtl-sdr, with antenna preamp which you can make it your self! 🙂
Nice video, it looks like you’re getting excellent images with that setup. I’ll have to build myself a QFH antenna one day too.
With this software can you do things such as adjust the bandwidth, narrower for cw or wider for SSB, AM, and can you adjust speed of agc so you do not hear the static sneaking in between every word. Can you do stuff like that with this software? First time I am hearing about SDR, it seems really interesting. Thanks for this video
Hi, yes you can adjust bandwidth and AGC settings. If you watch the video in HD at the top left is the bandwidth setting, and AGC is lower down on the left too. SDR Sharp is free so you can download it and have a look at all the settings for yourself too. There is also more advanced SDR software out there too like Linrad or paid software which work with more advanced SDR hardware that have more control over these things.
Good luck for the future with SDR!
I have an RTL2832 and was thinking of buying this upconverter but I was concerned about how well it will receive in the HF band because the RTL by itself doesn’t receive very well in every band except 700 MHz and up. VHF and the lower UHF range is complete crap as far as reception goes – even with a good outside antenna, so I’m concerned this product may not receive too well, or does that have anything to do with HF reception when paired with the Ham-It-Up upconverter board? Just curious….
Hi, what type of antenna and frequency range is your outside antenna tuned for? My RTL with the R820T tuner receives fine at the lower frequencies, but it of course depends on the antenna I use. If you buy the upconverter you’ll need a HF antenna, otherwise you won’t receive much.
The upconverter will simply shift the HF frequencies into the 100mhz range so the dongle can tune to it (e.g. so tuning to 110mhz will be really receiving 10khz).
I’m using a tri-band base station amateur radio antenna (Diamond model V2000A) with Belden 9913F coax. I’m a ham operator so I sometimes use this antenna for ham radio operating. However, when I use this setup for listening to even the amateur bands the antenna is tuned for the reception still totally sucks. I’m thinking it’s an issue with the device though because my ham transceivers show a near perfect match in those bands.
The 100 MHz range is one of the worst ranges on this device so I can pretty much forget even thinking of buying the upconverter because reception is terrible in the Hi-VHF range.
Interesting, I can only think of a few things that could be wrong (i’m no ham).
1) What tuner is your RTL device using? The E4000 and R820T are the best. The others might have poorer performance.
2) Your dongle might have gone ‘deaf’ by a ESD zap. Some dongles didn’t come with a protection diode.
3) I’m sure you have, but have you played with the RTL gain settings?
4) Front end overload from really strong signals?
Since your a ham, maybe a better option would be the softrock sdr kit.
I have the E4000 tuner, and yes, I have adjusted the gain settings for better performance. It’s not an overload issue because there are lots of signals that range from poor to great, but unless the signal is really strong I can’t receive it at all, and even then a strong signal is just barely there on the RTL dongle.
I’m not trying to compare this to my Icom R8500 receiver but I really thought it would work better than it does. Like I said, I guess I just got a bad one but 800 MHz is fine.
what visualisation software is this?
This is a free program called SDR Sharp. You can get it from sdrsharp.com
Most digital modes are USB too! 🙂
this could be true for the ham bands, but for utility signals .. it’s always or almost always usb
