BPQ32 and Ardopcf

Posted onAuthorPD9QLeave a comment

I’ve been running John G8BPQ’s ArdopC for a while now. Peter LaRue AI7YN has made a frok of ArdopC called ArdopCF.

https://github.com/pflarue/ardop

I want to use QtSoundmodem at the same time as ArdopCF. For this I need to create a “.asoundrc” in my home directory.

pcm.dsnooped0 {
    type dsnoop
    ipc_key 50000
    ipc_key_add_uid false   # let multiple users share
    ipc_perm 0666           # IPC permissions for multi-user sharing (octal, default 0600)
    slave {
        pcm "hw:1,0"
        channels 1
    }
}

pcm.dmix0 {
    type dmix
    ipc_key 60000
    ipc_key_add_uid false   # let multiple users share
    ipc_perm 0666           # IPC permissions for multi-user sharing (octal, default 0600)
    slave {
        pcm "hw:1,0"
        rate 48000
    }
}

# Point ARDOP to ARDOP2IN and ARDOP2OUT for rate conversion

pcm.ARDOP2IN {type rate slave {pcm "plug:dsnooped0" rate 48000}}
pcm.ARDOP2OUT {type rate slave {pcm "plug:dmix0" rate 48000}}


# combine the capture and playback
pcm.asymwine {
        type asym
        playback.pcm "ARDOP2OUT"
        capture.pcm "ARDOP2IN"
}

# make a default plug for it
pcm.!default {
        type plug
        slave.pcm "asymwine"
}

# define a plug for /dev/dsp
pcm.dsp {
        type plug
        slave.pcm "asymwine"
}

Jnos and QtSoundModem

Posted onAuthorPD9Q1 Comment

Today I was playing with Jnos, on my main system I have BPQ32 running with Direwolf and QtSoundModem. BPQ32 uses the Kiss port on Direwolf and the AGW port on QtSoundModem. Now I know that Jnos can easily handle the AGW interface/driver, so I linked Jnos with the AGW poort of Direwolf.

attach agwpe agw 44.137.31.70 8000
ifconfig agw description "AGW - 1200 baud port"
ax25 hport agw on
trace agw 0111

Direwolf is running on 144.850Mhz 1k2 and 430.950Mhz 9k6

Now I thought it would be nice to hook Jnos to QtSoundModem as well. But BPQ32 already uses the AGW port of QtSoundModem. Now I had read that Maiko VE4KLM had written a Kiss over tcp/ip for Winrpr. Who doesn’t dare don’t win. Here we go.

QtSoundmodem is running on 14.102Mhz 300Baud with 1100Hz on the left channel and 2000Hz on the right channel.

Autoexec.nos

attach winrpr qt0 44.137.31.76 8105
attach kiss qt0 1 qt1
#
ifconfig qt0 description "Kiss tcp/ip port 14.102Mhz 1100Hz"
ifconfig qt1 description "Kiss tcp/ip port 14.102Mhz 2200Hz"
trace qt0 0x211 qt0.log 1000
trace qt1 0x211 qt1.log 1000
#
ax25 hport qt0 on
ax25 hport qt1 on

The winrpr is the kiss over tcp/ip driver of Jnos. It`s written to use with Winrpr.

Boooommm Crashed……dammmm

It went so well. But now Jnos crashed. The winrpr driver is probably not written for two ports. Receiving is fine, but a packet that leaves the system on port qt1, Jnos can’t handle that.

So I removed this line (attach kiss qt0 1 qt1) from autoexec.nos and Jnos is running just fine. It is a pity that it only runs on 1 port, and that is the same as the AGW port. Maybe Maiko VE4KLM will look at it again.

Direwolf Vs QtSoundModem (part 2)

Posted onAuthorPD9Q1 Comment

Rx Only

Okay, that was a bit of a disappointment. I ran the test at 14.1022Mhz on 300 Baud. I think the conditions were very bad in those 24 hours.

For the test I use Kissutil.

https://www.mankier.com/1/kissutil

kissutil  can be used interactively for troubleshooting a KISS TNC. It is usable with direwolf and other generic KISS TNCs connected to a serial port. It can also be used as an application interface where each side places files in a directory for the other to process.

First I wrote two start files for the test.

Direwolf.sh

#!/bin/bash
cd /home/niels/testbed/
./kiss-direwolf -p 8009 -o /home/niels/testbed/rec-direwolf

Qtsm.sh

#!/bin/bash
cd /home/niels/testbed/
./kiss-qtsm -p 8105 -o /home/niels/testbed/rec-qtsm

The test ran for 24 hours, which is 86400 seconds.

timeout -s 9 86400 ./qtsm.sh

After 24 hours I can start counting the received frames.

As you can see this is very disappointing. Now I understand that the focus of QtSoundModem is more in the HF area. With a difference of 4 frames, the difference between Direwolf and QtSoundModem is minimal. In fact, too few frames were received in the 24 hours to make a good comparison. Is my opinion.

The next test we will try on 144.800Mhz the local Aprs frequency.

Direwolf Vs QtSoundModem (part 1)

This is about RX and not TX.

This has caused some headaches. I want to use one trx and one antenna for this test. (Icom 7300 and a Hyendfed)Now the problem is that Direwolf and QtSoundModem both use the sound card. Now you can’t both use the same sound card at the same time. So we will have to use two virtual sound cards and route the audio to these sound cards.  For this I use “pactl” with this I can manipulate the PulseAudio server.

pactl load-module module-virtual-sink sink_name=direwolf
And
pactl load-module module-virtual-sink sink_name=qtsoundmodem

Actually we are making a virtual audio card for Direwolf and QtSoundModem. Now we need to route the Audio from the input to the virtual audio card. This is possible with PavuControl.

Setup Direwolf

ADEVICE pulse
ACHANNELS 1
CHANNEL 0
MYCALL N0CALL
MODEM 300 1000 1200
AGWPORT 8008
KISSPORT 8009

Uhmmmmm port 8001.  I don’t understand that yet, in the config it really is port 8009.

Setup QtSoundModem

 

Now I haven’t fully read up on PulseAudio and pactl and the virtual cable/cards. Perhaps my wording and references are not quite correct.

Now I have the opportunity to test…..

Bpq32 with QtSoundModem and Hamlib

Posted onAuthorPD9QLeave a comment

Yesterday I added 2 HF ports to my Bpq32 Node / BBS. I have chosen to use QtSoundModem and Hamlib. QtSoundModem is a Linux port or Soundmodem from UZ7HO. I use Hamlib/rigctld to take control of the Tranceiver. QtSoundmodem and Hamlib run on a different Raspberry than the BBS and Node.

After some testing I found out that I need Hamlib version 3.3 to control the icom 7300. The versions 4.0 and 4.1 do not work for me. Apparently the icom 7300 is not being initialized. Can’t actually find out why this is. With the command “rigctld -l” you get a list of which tranceivers are supported.

So I need number 373 for the Icom 7300.

/usr/local/bin/rigctld -m 373 -r /dev/ttyUSB0 -s 19200 -T 44.137.31.76 -t 4532 &

In the QtSoundModem.ini I have in the [Init] section.

HamLibHost=44.137.31.76
HamLibPort=4532
PTT=HAMLIB
PTTBAUD=19200
PTTMode=17

Now the bpq32.cfg

PORT
 PORTNUM=4
 ID=14.1022 +1100Hz
 DRIVER=UZ7HO
 CHANNEL=A
 PACLEN=80
 CONFIG
  ADDR 44.137.31.76 8101 ; AGW port of QtSoundModem
  BEACONAFTERSESSION
  MAXSESSIONS=5
ENDPORT

PORT
 PORTNUM=5
 ID=14.1022 +2000Hz

 PACLEN=80
 CONFIG
  ADDR 44.137.31.76 8101 ; AGW port of QtSoundModem
  BEACONAFTERSESSION
  MAXSESSIONS=5
ENDPORT

With Hamlib it is also possible to control the TRX from Bpq32. I immediately added a Robust 300 packet port to Bpq32 with rig control. Here is an example.

PORT
 PORTNUM=3
 ID=Robust 300 ;(RPR Packet)
