Larry, SDR Console only takes IQ from SPY server, so watch the bandwidth. Don’t have any Wi-Fi in the chain if you can possibly avoid it. Crunchy audio could be due to bandwidth issues. Simon Brown, G

Hi, SPY Server used to work with SDR Console – if there’s a problem I can check for any changes. Simon Brown, G4ELI https://www.sdr-radio.com

FWIW, If you’re working in C/C++ https://pugixml.org/ is an excellent XML library. Simon Brown, G4ELI https://www.sdr-radio.com

There’s nothing wrong with Linux, it’s just a minority operating system. I actually run Ubuntu myself for a few projects such as a DX Cluster. I doubt anyone, anywhere has as many different SDRs as my

Mike, There’s no reason why SDR Console does not work with a Airspy HF+ on a W7 system, 32-bit or 64-bit, in fact I test with a W7 32-bit myself. Let Windows apply any outstanding updates – there may

Frank, Just FWIW I keep my Pluto + TX preamp/amp cool with this excellent USB fan. Draws only 1 or 2 watts, on low speed it’s quiet. In general it doesn’t get too hot in Cornwall, nevertheless I prefe

Hi, Just give a RF64 file that doesn’t work to the plugin developer. You (he) should skip chunks he’s not interested in, then it’ll be fine. Simon Brown, G4ELI https://www.sdr-radio.com

Hi, I think the player is a plugin, not Youssef’s original. Simon Brown, G4ELI https://www.sdr-radio.com

OK, Looks like the RF64 player will not play files with unexpected chunks – ideally it would just skip over them. I have a ‘xml ‘ chunk with my own info about the file, maybe this is what caused the p

Very good point. Simon Brown, G4ELI https://www.sdr-radio.com From: airspy@groups.io <airspy@groups.io> On Behalf Of prog Don't use receivers optimized for SNR and Dynamic Range to do any measurements

Just FWIW (how to suck eggs), To convert from dBm to dBμV just add 107. Simon Brown, G4ELI https://www.sdr-radio.com

Dave, Thanks – I can play it back OK. I’ll look at the structure tomorrow with luck. Simon Brown, G4ELI https://www.sdr-radio.com

Dave, Please make a sort (5 minute) RF64 recording in SDR#, upload it somewhere and send me a link. Maybe there’s something special with the format used in SDR#. Simon Brown, G4ELI https://www.sdr-rad

Dave, SDR# doesn’t use the SDR Console XML chunk in WAV, rather depends on the filename. You’ll have to rename the new file in accordance with the SDR# format. Were SDR# to support a meta chunk then I

Dave, Use the Data File Editor, part of SDR Console. This can save as smaller files or as RF64. You can extract only the part of the recording of interest. https://www.sdr-radio.com/data-file-editor S

An advantage of the transverter – it transmits! For EME a masthead preamp with NF < 0.5dB is common. Of course, wideband receivers are a different proposition. Simon Brown, G4ELI https://www.sdr-radio

Jeremy, I beg to differ. I have an IC-r8600, the ICOM r8600 IQ is good, there are several software packages which support it via a USB cable, the result is as good as the radio itself. Connecting a se

But, I’m using the Q5 Signal transverter, 144 MHz ó 28 MHz. The Q5 NF is < 1dB (published figure), this is the key. http://q5signal.com/index.php?route=product/product&path=60&product_id=52 Simon Brow

Discovery should be better than the 9700. I ‘think’ the noise figure for the discovery is 4 to 5 dB, so a masthead preamp will help. FWIW I use a Q5 Signal transverter + FDM DUO on 2m, NF is significa
