Jnos and QtSoundModem

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.

MHSave and Python

Today I am playing with Python and Matplotlib. In BPQ32 you have the option to save the Most Heard list (MH) when you close BPQ32. This contains a lot of data that you can use. Above I made a plot of the received stations and the number of packets I received at 14.1022Mhz + 1000Hz at 300Baud. Now I am not a world programmer, so this could probably be easier or different. Below the script I have written and used.

#!/usr/bin/python3
import re, csv, zlib
import matplotlib.pyplot as plt
import numpy as np

#First get the data form the right port. 14.1022Mhz 300 Baud HF Packet

port4 = []

with open("MHSave.txt") as f:
        found_port4 = False

        for line in f:
                if line.startswith("Port:4"):

                        found_port4 = True

                if found_port4:
                        if line.startswith("Port:5"):
                                break
                        else:
                                mod_string = line.replace('||', '')
                                mod_strings = re.sub("via.*$", "", mod_string)
                                port4.append(mod_strings.rstrip('\n'))

with open('port4.txt', 'w') as fout:
        fout.writelines("\n".join(port4[1:]))

#print("\n".join(port4))

# Convert it to a csv file
with open('port4.txt', 'r') as in_file:
    lines = in_file.read().splitlines()
    stripped = [line.replace(","," ").split() for line in lines]
    grouped = zip(*[stripped]*1)
    with open('port4.csv', 'w') as out_file:
        writer = csv.writer(out_file)
        writer.writerow(('Epoch', 'Pack-rev', 'Call', 'Month', 'Day', 'Time'))
        for group in grouped:
            writer.writerows(group) 

# Matplotlib create a nice Plot of the received calls

filename = 'port4.csv'
with open(filename) as f:
    reader = csv.reader(f)
    header_row = next(reader)

    #Get Packets and Calls received
    packs, calls = [], []
    for row in reader:
        pack = int(row[1])
        call = str(row[2])
        packs.append(pack)
        calls.append(call)

x = np.arange(len(calls))

fig, ax = plt.subplots()

ax.barh(x, packs, align='center')
ax.set_title("Call and Packets received on PI1LAP")
ax.set_xlabel('Received Packets')
ax.set_ylabel('Station Callsigns')
ax.set_xticks(packs, minor=True)
ax.set_yticks(x)
ax.set_yticklabels(calls)
plt.tight_layout()

Kantronics KPC4

Today I have been working on a Kantronics KPC4 which I bought from PD4R. I am very happy that I can add it to the collection.

Kantronics KAM_KPC-1-2-4-2400_Installation Manual

Kantronics KPC4 Firmware

The nice thing is that such modems can also be accessed from BPQ32. Here is a small example.

Bpq32 with QtSoundModem and Hamlib

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

PORT
 PORTNUM=5

 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)

Aprs Weather Beacon

Today I’ve been messing around with an APRS weather beacon. Now Direwolf and Linbpq and Jnos can send an aprs weather beacon. It turns out that this is quite precise, with the format of the beacon.

#!/bin/bash
# The weather beacon have to look like this....

My weather station uploads its data to wunderground.com. Now wunderground has the option to read this again with an api key.

https://api.weather.com/v2/pws/observations/current?stationId=IKORTG9&format=json&units=m&apiKey=yourApiKey

You can read here how and what.

After a lot of messing around with a bash script, I am able to create the correct format.

WGK=39km/h Wind guts in Kilometers per hour
GRD=58° Wind direction in degrees

The file I need to broadcast an APRS Weahter Beacon looks like this.

pd9q@pancake:~/linbpq/wx-project $ cat ~/linbpq/current.txt
Feb 09 2021 13:00
086/004g008t028r000p000P000h75b10007

The config file for Linbpq looks like this, this is in the aprs section of bpq32.cfg

WXCall=PD9Q-7
WXFileName=/home/pd9q/linbpq/current.txt
WXComment=/Weather Station JO11VN
WXPortList=1,5,IS        ; comma separated list 
WXInterval=10            ; mins

For Jnos in the autoexec.nos in the aprs section

aprs wx call PD9Q-7
aprs wx stat "Weather Station JO11VN"
aprs wx pos "5133.52N/00348.15E_METEO

For direwolf in the file direwolf.conf

Direwolf Aprs packet look like this.

BPQ32 Aprs packet look like this.

PD9Q-7>APBPQ1,WIDE1-1:@091338z5133.52N/00348.15E_069/005g006t028r000p000P00
0h75b10007/Weather Station JO11VN

Learned a lot.

BPQ32 Yapp file transfer

BPQ32 and QTermTCP support the Yapp Protocol. Let’s take a look at how that works.

First we have to great a Directory  ” Files”  in the root dir of Linbpq. The user Pi must be the owner of the Directory.

cd /home/pi/linbpq
mkdir Files
ls -l
drwxr-xr-x 2 pi pi    4096 nov  1 12:10 Files
* If the user Pi does not own the directory "Files", you can change that with.
sudo chown pi:pi Files

Now we can set QTermTCP to use the directory “Files” for uploads and downloads. In the top menu choose ” Yapp” , ” Set Receive Directory” and choose the correct directory (Files).

First we need to connect to a local BBS that supports the YAPP protocol. Now I have set up a BBS here for this test. As modems I use two Ninotnc`s connected with a null modem cable.
Now we are ready to send a file. Again choose in the top menu “Yapp” and “Send File” Now you can choose which file you want to send.

Here we go…..

File compleet.

The same file but compressed.

NinoTnc progress

Boy, I can hit my head against the wall. I made a very rookie mistake. I had  soldered a number of Leds the wrong way round.  Tsss before I finally invented that. Very stupid.
But when I finally found out (it’s even in the description on the tarpn website) it now works the way it should.

Let’s test how the reception is. (aprs on 144.800Mhz @ 1200 Baud)

I feel like he is a little deaf. Looks like he’s missing some frames. Maybe it’s the setup I’m using. I am using a Yaesu ft7800 with the NinoTnc directly on the Mini Din of the radio. I have to figure this out, I will read the Tarpn website one more time.

First let’s update the flash.

Mmmmm, let’s give it a go.

Nice…

I am very happy to be able to add this (Nino)TNC to the collection.

Linux Port of UZ7HO’s Soundmodem

Very good news, John G8BPQ has ported Soundmodem from UZ7HO to Linux.

Mail from John G8BPQ.

Andy UZ7HO has allowed me to port his Soundmodem to C so that it can be run run Linux systems. See

https://www.cantab.net/users/john.wiseman/Documents/QtSoundModem.html

This is pre-Beta software. It has been tested by several people but is likely to still have bugs.

Guide…BPQ User and Sysop Commands

Bill PY2BIL has wrote a great guide with Sysop and User commands.

PY2BIL wrote,

Since I started with my BPQ BBS I was looking for an easier way to access the documentation and find what I needed at the moment, so as many do, I wrote down what I used the most along the way. Recently I decided to take the plunge and write the ‘Official BPQ Cheat Sheet’ (hihi) based on the official documentation that would make my life easier. Some of the commands I found in the documentation are flagged as obsolete or no other reference was found and I suspect that many changes that John did are still not formally documented and may be laying around in this forum.

Thanks Bill great document.
