Re: IGFILTER in Rx only iGate

What q-construct are you tagging the APRS packets with? Is it qAR? This would imply to APRS-IS that you are a TX I-gate. If you use qAO instead, this should tell APRS-IS that you are RX-only. Not sure if that would solve the problem. Also not sure if direwolf APRS-IS client lets you specify the q construct. if not, you can run another client on top of Direwolf modem, eg. APRSIS32. But if the confit option is missing in direwolf APRS-IS client, someone should probably add it.

While I agree with you, we are not given any control over that. While my station is not receive only, the other day there was a short band opening and I received a single packet from a distant station 400 miles away?via RF,?and for the next three hours I received their once per minute weather station packets. I counted all 180 of them. Seems like a lot of wasted bandwidth. Not to mention it fills?up my logs with useless data. See if you can spot both problems!

Putting aside the fact that ALSA doesn't seem to work with the Signalink on Jessie, how do I know what is an appropriate INPUT audio level for use with Direwolf?

Per the user guide, you want your average reported report level to be around 50.? You'll see a lot of different levels out there from mistuned packet stations so just try your best.


How do I know when I am saturing the input level? Do I just use Fldigi waterfall to set it? Is the audio input level independent of the receive application?

Direwolf will tell you when the levels are too high.

Re: Signalink Raspberry Pi (Jessie) audio setup

 

Hi Dave,
well,
putting the J2 jumper in place on the Signalink has boosted the receive audio. I now see Direwolf report audio levels in the 20s (typically) with the RX knob midrange setting, whereas before jumpering, the levels were typically single numers 3-4.

Good Morning John..

?Well, every OS is different in it's mixer settings.? What radio are you using and how is the Signalink connected to that radio?? I assume the RX knob on the front of the Signalink is turned to 100% volume?
?The radio (FT-857D) is connected via the 6 pin DIN data port on the rear panel of the radio, same as in Win 7. The settings of the Signalink are the same as for the Windows 7 ?setup, i.e. the RX knob is midrange. I still ?do not understand the Linux audio levereport format. Is this supposed to be the same as the Win version or diffel rent?

Well, I can't speak specifically to the SIgnalink but some sound card drivers can have different gain levels.? Here is one URL that talks about what might be happening when comparing to Windows:

??

Also, if you're not aware, there is a bug in the Windows USB sound card driver that impacts the Signalink.? It overdrives the levels but you can work around it:

??


hiiting the F6 key does NOT make any recording setting available in Alsamixer.

Ok.. this is the same way as on my Navigator.? All user controls are via the front facing Signalink knobs, the DATA port level settings on the FT857, etc.

Agreed!


When I configure and run direwolf, I see packets being reported typically with audio levels = 2 to 4 ( e.g. 4(2/1). This is quite different from what is reported using the same Signalink and Windows 7 (typically audio level = 50 to 60). What's this mean? Is the Linux report different?

I am running successfully an RPi Direwolf SDR APRS Rx-only Igate on VHF on 144.390Mhz.
?
If I want to add a second SDR dongle for UHF on 445.925Mhz. on the the same RPi for Rx-only Igate.
?
How do I set it up on sdr.conf?
?
Or should I run another instance of direwolf with a different sdr1.conf with CHANNEL 1 to select second dongle and use a different callsign SSID.
?
rtl_fm -f 445.925M - | direwolf -c sdr1.conf -r 24000 -D 1 -

Has anyone tried that on one RPi Direwolf with two SDR dongle to receive on VHF an the other one on UHF.

Re: Periodic audio device statistics

 

Great news. It's working!

I installed the Gnome Alsa Mixer as suggested by Patrick. I had to check the "Record" box and the audio level jumped up. I adjusted the audio level (was way too high) and it is now decoding.

There must be a way to change this setting from the command line? Maybe the documentation should include this.

Thanks very much to Patrick and David. I doubt I would have got it going on my own. I've been working on this for weeks, the bulk of the things I've tried (and didn't work) are not in this thread.

I'll restate how I corrected the original problem I posted of the Periodic Audio Statistics not showing in the terminal...

In my configuration file I had "ADEVICE - plughw:1,0". Once I removed the dash, as suggested by David, the statistics started showing. Also this changed the what Direwolf showed as my device for receive when it is started.

Thanks again to everybody for the help.

73,
Randy

Re: Periodic audio device statistics

 

I loaded the Gnome ALSA mixer on my Pi, as I'm more comfortable with a GUI. Some of the input sliders have a check box marked "Rec." (Record). Perhaps that is cause of your issue.

Re: Periodic audio device statistics

 

David,

Okay. We're not there yet, but we're getting somewhere.

?

I removed the dash from the ADEVICE line and now the terminal indicates "Audio device for both receive and transmit: plughw:1,0 ?(channel 0)". I don't know where the dash came from. I thought all I did was remove the pound sign at the beginning of the line. Thanks for that tip. I wouldn't have found that in a million years.

?

Removing the dash also allowed the periodic audio statistics to work. I can now see that the audio level coming in to Direwolf always shows zero. I tried various audio levels with the squelch open and also with a capacitor in line. I have an audio isolation transformer I tried in addition. I tried playing the weather channel which also always indicated the audio level at zero.

?

Beatiful audio comes from the output port of the sound card. I can adjust the level of the audio using the mixer in Linux. I am using Alsamixer to adjust the level, so that was already in my Pi. There is no feedback in the audio at any level. I don't think the quality of the audio is a concern right now. More the complete lack of it reaching Direwolf.

?

I also modified the modem line as you suggested.

?

I am running "Raspbian Jessie With Pixel" dated 1/11/2017. It is what is currently on the Raspberry Pi web site.

?

I have a degree in electronics and over thirty years professional (and amateur) experience in that area. I designed and built my own 440 repeater controller from scratch using a basic stamp 2 as the microcontroller. I wrote my own code for the stamp. You can get as technical as you like about electronics and radios.

?

I would say I am more of a beginner in Linux, though I have worked with it occasionally over the years.

?

I have a pretty good parts supply so I can add the LED when I get a few minutes. I don't think that is a big deal if the audio level coming in is zero.

?

I had to click view source again to read your post but that's no big deal.


I was advised to include my call. You may have already seen it in my configuration file.

I'm responding to my own post for an update.... This is a portable telemetry system, so ended up getting recommended GPS unit.


So, now implement TBEACON with compressed location using COMMENTCMD. Shows up fine in findu.com raw data. I insert that data into my server database event_log table.


Looking in?symbol.c I see that Ambulance is the default?symbol with ssid="-1"? and no SYMBOL specified in the beacon config.

i orderd a OP1 in October and it came from China just at the end of November
it was DOA
they wanted me to send it back then they would send me another
of course the return shipping was more than the item
i just ordered another
it came a month or so later and it was also DOA?
different failure, but still non functional
so im not holding any hope of ever having a OP1 that runs

Glad your is running !
