Rasberry Pi WSPR Decode
|
Hi Folks and HNY to all.
Rasberry Pi three running WSPR Decode on QCX receiver I'm following the information from VK1UN and a blog by someone called Marxy the link to VK1UN info:- Everything seems to load and run on RPi3 with 2017-08-16-rasbrian-stretch.img but I can't identify the soundcard device to use. With a USB soundcard I get multiple options for input and output sources. Please can someone help me to identify which one I should use? I have 14 possible options for the input and 25 options for output and the error messages don't help. Thanks, Mike G8NXD |

I've been using the Marxy software and a Pi 3 for a while - works well. My settings are: Input???? sysdefaultCARD=Device Output?? sysDefaultCARD= ALSA Both Mono,? and I guess the Output parameter isn't relevant as I'm only using it for Rx. My audio device is a u-Green USB 'dongle' Regards Dave G3WUN On 04/01/2018 09:31, Mike W wrote:

Thankyou David, That seems to work but unable to set levels on mic or speaker.

I have the soundcard 'USB PnP device' set to Alsa mixer, but not able to control of mic level. not tried speaker yet. ideas?. I'm getting audio displayed on waterfall but no decodes yet on 40m On 4 Jan 2018 at 9:46, David wrote:

Not sure where your mic and speaker levels controls are - I just take the video from the HDMI port on the Pi.

If you have two windows open and set the volume slider in the decode window you should decode anything heard. The only other thought is that as I've had my setup running for some months I may be using an earlier version of Debian (Jessie ?) and perhaps Stretch is the problem?

Hi Dave,
I too cannot get WSJT-X v1.8.0 to recognise my soundcard on my Raspberry Pi. I get a long list of options but my nearest input to yours is:-?Input??sysdefaultCARD=SET (not 'Device') and Output?? sysDefaultCARD= ALSA is there but does not work. All I get at start up is an error message in WSJT-X is 'Error in Sound Input' then 'Error in Sound Output' and 'Audio data not being fed to the audio input device fast enough'. Early versions of WSPR found my USB soundcard straight away. Any ideas what to try next please? Ken G4APB |

Here you can find more info about WSPR on Raspi and sound cards settings. Working fine on my Raspi 2 B without GUI. On my notebook I tried also to receive WSPR signals with QCX 40... without any modifications of CW filter. Tested with Linux Mint & WSPR4.0 r4522 & QCX 40. First change BFOfreq in WSPR.INI (or Setup/Advanced/RX BFO (Hz)) to center freq of CW filter in your QCX (550Hz for my QCX). In WSPR main window set Dial Frequency to 7.039550 (7.040100 - CW filter center freq). Tune your QCX RX on 7.039550 and enjoy :) 73&GL Andy 9a3jh On Saturday 06 January 2018 08:37 PM, KENS 2ND ACC via Groups.Io wrote:

开云体育Hi Ken, My setup is very slightly different to yours: QRP Labs Rx (not QCX) mono output >> Mic input
(mono) of this USB sound adaptor This is connected to a RPi 3 running WSJT-X ver 1.7.0 and Raspbian Jessie. My Rx and Tx? audio settings are as per the attached pics and for
me, the TX setting isn't relevant as I'm using a U3S to Tx. (Just
as a test I changed it from ALSA to another without getting any
error messages.) (The blue highlighted option is just where the
curser is? positioned) Perhaps the different later versions of the WSPR and RPi OS s/w that you? are the cause of the issues? but your error message 'Audio data not being fed to the audio input device fast enough'. is strange. Perhaps if you already have a USB audio 'dongle' it might be worth trying ? I have used a very cheap one ?2 in the past which worked. Hope the above helps. Dave G3WUN

开云体育Hi Dave, Thanks for the screen shots but I don’t see your first line the same in either. I have set my external usb dongle (C-Media headset/mic adaptor) to default but makes no difference. Whatever happened to the simple direct reporting of the soundcard in earlier versions of WSPR? I also have a better quality Griffin iMic USB soundcard but that does not get seen by WSJT-X either, but is seen OK by the Raspbien ‘volume’ icon. I tried running my Raspi in Turbo mode but max speed just crashed it. ? 73 Ken G4APB ? From: [email protected] [mailto:[email protected]] On Behalf Of David

开云体育Ken Sorry for the confusion, it was in the body of my email. It should have read "My Rx and Tx? audio setting OPTIONS? are as per the attached pics and for me, the TX setting isn't relevant as I'm using a U3S..... etc" Looking back at your earliest post it doesn't say which version
of the Pi you're using. For WSPR decoding I haven't used other
than a Pi 3, and if you have a Pi 2, perhaps the suggestion by
Andy, 9A3JH may be appropriate ? Several months ago I did try an
early Pi (and optimistically, a Pi Zero) but without success. Other than that I can only think that it's? either the WSJT-X and Raspbian versions which are causing the problem. IF you are using a Pi3, perhaps installing earlier WSJT-X 1.7.0 and Raspbian.? A it of a pain for sure. Dave G3WUN

Hi Dave,
I only have Raspi version 1's, both run early versions of WSPR but I was trying to upgrade them. Having spent a great deal of time on them and tried the miriad of different approaches around, I have not achieved a working solution with latest firmware. Time to shelve this particular project. Thanks to all for your help anyway. Ken |

Yes, I? don't find BFO parameter in WSJT-X :( Other idea will be to use some other software to shift audio signal from QCX filter (~ 500-700Hz) to WSJT-X bandpass (1400 -1600Hz). Spectrum Lab () is very good HAM audio software (tnx DL4YHF) and can do this. Connect your QCX to sound card input -> Spectrum LAB -> WSJT-X software. To do this we have to use something like Virtual cable software(WIN) or aloop or Pulseaudio(linux) and connect audio output of Spectrum Lab to input of WSJT-X. This is "litle bit" complicated solution and I am not sure if this will work on Raspberry PI. I tested similar configuration on linux machine with alsa loopback and Spectrum Lab. Hardware solutions ideas (not tested): Maybe we can just take QCX audio directly from IC5 pin 1 -> sound card input. Use C 10uF and 1-5k resistor in series from pin1 to sound card input. Or use QCX like SDR receiver, connect sound card to I/Q signal, IC5 pin 1 and pin7. As per info from QRP labs web, AF filter has to be changed, replace C43-C46 with 47nF (or less). 73, Andy e21/9a3jh On Sunday 07 January 2018 03:51 PM, SM7ETW Jan wrote:
