Re: quisk setup for old Softrock RxTx 6.3 - no transmit audio, problem is in software - Quisk or audio setup. (STILL not working right!)
I'm transmitting into a load (the softrock output is about 2mw), and using the dongle antenna, a few feet away.? I could set up a separate attenuator, but I've found that sufficient for working on my other radios - and it does pick up the signal no problem (the coax to the load is a bit leaky).? I don't know what the attenuation really is - I'm more interested in the signal shape and sidebands (and so on).? If needed, I can set that up - I've got a good 50 ohm step attenuator for doing measurements.

I adjusted the gain, and it does appear to be the transmitted signal itself.? The signal would be (FM mode) a flat-topped curve, with the flat portion about 5khz wide, and the sides slowly sloping down to around 20khz (each direction), where they start dropping more steeply.? It appears to be noise of some kind - a high-pitched static (when in FM mode, listening to the output of the dongle audio).? For most of my tests, the gain on the audio out to the softrock didn't affect the shape of that signal.? (In SSB mode, it was differently shaped - two or three peaks, with the highest peak rather broad.) ... I may be onto something.? Somehow the computer audio is picking up a high-pitched static - but I can't figure out where.? It's not coming from the softrock (or as feedback from softrock audio).? When I set the mike gain low enough, when I speak the mike audio over-rides the static, which vanishes for a second or so then fades back in.? I've been playing with turning off and on various audio devices, but without luck so far.? (Laugh!) It would be my luck to have acquired a computer with bad audio, but the evidence goes against that (the sound only appears with Quisk).? Even then, recording and playing back the audio from the mike under Quisk doesn't show the noise. I'm also picking up a strong AC buzz in receive using the softrock, but only when I am connected to my main antenna (fan dipole at 50ft - hanging off my tower).? I have a 10m dipole between the house and a tree - no buzz on it that I can detect.? The symptoms I'm seeing rather remind me a little like being in a rather strong RF field... except my dongle isn't picking it up (I AM getting a signal into the dongle from a religious station somewhere in the area - but none I know of within a couple of miles - and it's not on the real frequency - maybe an image).? The audio itself being put out (by my dongle) is strange - a high pitched hiss or buzz that I've not encountered before (not plasma TV - haven't heard that buzz in a while). My wife reported a strong buzz from her computer when I used my main 2m radio (on .52)... the shack and everything here is grounded and there should be nothing there as well.? The P/S for the radio is not connected to the softrock, and turning it off doesn't seem to make a difference with the problems I'm having.? Still, I'm going to scope that to make sure I'm not getting anything there! It's a tough one... but I should be used to those by now!? (GRIN!) Next test - try a laptop (I think I have one with Quisk on it). Thanks for 'listening' - maybe with suggestions, we can iron this one out (and I can get this monster on the air!)

I gave up using QSD/QSE? SDR's as I never found sound cards to be satisfactory, adjusting amplitude and phase never seemed to have any effect. With DDC/DUC SDR's a simple USB sound dongle and just an Ethernet connection to the PC/SBC with no fiddling with adjustments necessary. 73 ... Sid. On 06/12/2019 19:10, Robert D. Bowers wrote:

Re: quisk setup for old Softrock RxTx 6.3 - no transmit audio, problem is in software - Quisk or audio setup.
¿ªÔÆÌåÓýFOUND!!!Crazy thing.? Since my transmit audio in won't be over 2.6K or so (JT65/FT8/PSK31/voice/etc.), I'd had the mike audio in set to 8K (one of two settings).? I thought I read somewhere that the audio in for mike (or digital as I've been running it) didn't require the maximum bandwidth set to the same setting as the IQ bandwidth (I guess for that side of the system - the audio in and out, it could be less than the radio side).? I changed it to 48K and now I have audio out and a signal out.? (Signal condition/modulation - next to check!) I also found another thing...? Sometimes you have to play with a combination of mixers to get a mike going.? I use the front mike of the "small footprint" computer used with the radio, and could not get any audio on the TX test.? I messed and messed with it, without luck.? Finally I went back to QasHctl and found that there was a single setting involving the front mikes that wasn't set.? I changed that, went back to Alsa Mixer and found that I had to change the audio in sensitivity again, then changed the bandwidth for mike audio - and everything started working. BTW - a small thing that might be useful - there are adjustments in the audio setup for each channel (output level and phase), but I couldn't find something that after adjusted, would adjust the transmit audio level (increase or decrease power in FM mode, for instance).? That might be a nice option to have as one of the buttons or as a slider. Thanks for the suggestions and "listening"!!! Bob N4FBZ On 12/5/19 8:37 AM, jimahlstrom wrote:

Re: quisk setup for old Softrock RxTx 6.3 - no transmit audio, problem is in software - Quisk or audio setup.
¿ªÔÆÌåÓýThanks!? That might help.I'm wondering if there is a module or driver that is interfering - something that needs to be blacklisted.? I know for a while it was intermittent - the transmit levels would be off for part of the time, and varied at other times - once in a rare while full output.? That was through the measurement of the output of the transverter - I didn't measure the audio - and that was before something changed the second time and suddenly nothing worked.? That was some time ago. It's not the drivers for the USB audio - because separate from Quisk, the audio works fine. I checked the config file for Quisk.? Nothing there that seemed wrong, but I did see (and remember making) a asoundrc file that I renamed to a temp file (it was to try to fix a previous problem involving the digital in/out).? That did cause one tiny change - now when I click on PTT, there is a blip of RF on my meter (set to AM or FM for a carrier).? That wasn't the case before - no blip.? If you don't mind, I'll copy and paste the quisk_settings.json file in a post (reply) and maybe someone will spot something I didn't.? I could also copy-and-paste a second quisk file in the home directory - quisk_init.pkl. ? ? (Thanks to Sid for reminding me of where the file was and the name!) Thanks again!

On a new computer I usually remove ~/.quisk_conf.py and use the quisk Config tab to set up a new radio. It's a long time since I've used the SR v6.3 and successors in the Softrock fold but I still remember some things. The last assistance I gave to a friend setting up an RXTX was to consider the sound card that's connected to the Softrock as part of the rig and not a "Sound Card" as he was getting confused with the use of the 2 cards. Only things I can suggest, try alsa hw:0 and hw:1 instead of pulseaudio. With the SR 6.3 up with quisk, check "fuser -v /dev/snd/* especially for "m" flags which show the cards as writeable. ??? Softrock TX chain???? 73 ... Sid. On 05/12/2019 00:30, Robert D. Bowers wrote:

History of this problem - more recent. I lucked into this small footprint computer and thought it would be a useful thing to have a dedicated computer running radios.? (Using Ubuntu 18.04) I first installed Quisk.? It worked.? Upgraded to gain some functions I wanted, it worked.? Then months later started having problems.? Found the one affecting the Si570... but still something a bit strange.? Then I discovered this problem.? Installed Pulseaudio volume control.? That helped in diagnosing some receive issues, no reliable Tx.? Installed alsamixer, could not find anything wrong.? Updated Quisk to most recent version.? Still no Tx audio to radio.? Installed QasHctl, still nothing wrong found. Finally joined here and asked for help. If I can figure out which file is the config file for Quisk (most recent version), I'm going to look through that.? I'd activated the digital signals some time ago, but my present setup doesn't require that - and maybe there is some sort of interference there. It's a tough one.? Very irritating and frustrating.

I've even looked into the update idea a bit, but what I found either didn't apply or didn't make a difference. It's got me really frustrated.? I've been trying to get on 2m ssb for many years, but don't have the money to buy something (unemployed and disabled - although that may change as I may finally have a job I can handle starting next year).? Getting this going again would also open up some other possibilities on HF as well.? (I may even try to scrounge parts - I've always been rather good at that - to build a 6m transverter.)

quisk setup for old Softrock RxTx 6.3 - no transmit audio, problem is in software - Quisk or audio setup.
I've got a major headache - I don't know what changed, but I cannot transmit anything with my softrock - no signal out.
The setup: Softrock RxTx6.3 modified for broadband use (wideband low power class A amp in place of power amp). Transverter - 10m to 2m (working right). Computer: Dell D2500CC dual core 1.86 ghz 4gb ram dedicated for running radios, single monitor 800x600 (small size, may change out for slightly larger one). Ubuntu 18.04.3 LTS. Quisk 4.1.46 Internal audio on hw:0 usb audio on hw:1? (two different audio devices tried - a sound blaster unit and a good Realistic unit) Problem: no transmit audio.? RxTx goes into transmit (using the USB I2C interface adapter), but no audio out (tried two different USB audio units).? Audio and RF checked with an oscilloscope. Problem started a few months ago, with the receive being off in frequency (and sometimes no receive whatsoever).? That time, I found a bad ground connection in the softrock, which when fixed made communicating with (and changing frequencies with) the softrock a lot more reliable.? Transmit audio also stopped working (and hasn't been right since).? It's not the radio as far as I can tell - no audio is being generated by quisk.? This was true no matter which audio device was used for IQ transmit. Test audio (computer voice through left and right channels) via the computer setup screen works fine - both channels will generate audio.? Waveform clean, audio sounds good in headphone when plugged into port. Tried Alsa audio, Pulseaudio settings, and installed mixers for both (neither made any difference).? I found that using Alsa audio or Pulseaudio in the Quisk radio setup made the system rather unreliable - sometimes the spectrum graph would be working, but no audio out.? Other times, no response visible on the graph.? I couldn't detect any pattern to this.? Using hw:0 and hw:1 in the Quisk radio setup was the only really reliable (as far as receive) setup - tried hw:1,0 for the USB device, still doesn't work. Sometimes using Alsa or Pulseaudio would cause Quisk to crash, every time I tried to transmit. The most reliable mixer was QASHmixer, but still no transmit audio.? One funny thing was that with the built-in audio mixer (under Ubuntu setup) and with the Alsa mixer, either both digital and audio would be turned on, or turned off.? I couldn't turn off the digital mixer without the line audio mixer (for the USB device output) also turning off. I've tried reloading Quisk (a couple of months ago) with no change in symptoms. I'm at a loss now.? Any suggestions on where to check next?? It doesn't seem to be hardware related at all... something between Quisk and the digital signal going into the USB audio devices! Thanks for any help! Bob N4FBZ |

Re: Two simultaneous radios with QUISK ?
Hi Peter/Jim,
It took me some time to prepare my 2nd HL2 (build 8) for testing but now I am quite ready ! It seems that when running two HL2 simultaneously in the same network, they should receive unique IP?s from the DHCP server in the QUISK startup. I wonder if it is sufficient to first name each HL2 board as a "radio" (HL2_nr1, HL2_nr2 etc.) and thereafter, in their ConfigScreens, specify the board number( 1, 2? etc.). I may not need this normally but it would be nice to have an option for some special situations. 73 de Heikki (OH2LZI)? |
