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()
plt.show()

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.

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
  MAXSESSIONS=5
ENDPORT

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)

PointoPoint link between two Ninotnc`s

Today I am playing with tncattach, I thought it would be fun to test this with the Ninotnc`s.

I have connect the first Ninotnc n9600A4 to my rpi 4 and install “tncattach” on it. The TNCs are connected with each other by means of a short cable.  Cross cable. The tnc are running 9600Baud

TNC1             TNC2
RX                   TX
TX                   RX

# If you don't already have a compiler installed
sudo apt install build-essential

# Clone repository from GitHub
git clone https://github.com/markqvist/tncattach.git

# Move into source directory
cd tncattach

# Make program
make

# Install to system
sudo make install

The next thing I did was setting up a pointopoint link. But first attach the modem.

sudo tncattach /dev/ttyACM0 57600 -d --noipv6 --noup --mtu 329
sudo ifconfig tnc0 10.0.0.1 pointopoint 10.0.0.2

The second Ninotnc n9600A3 I have connected to my rpi 3

sudo tncattach /dev/ttyACM0 57600 -d --noipv6 --noup --mtu 329 
sudo ifconfig tnc0 10.0.0.2 pointopoint 10.0.0.1

I made a short video of how it works.

That was Fun….

Kantronics KAM All Mode

Today I am the lucky one again. I have added a new modem to the collection. Namely the Kantronics KAM All Mode.

The KAM is using the oldest Firmware that I know of. Version 5.00. The newest is version 8.2. Have a look at this link
Here can you find the Kam Manual.
It is the third Kantronics modem I have. I have the KPC3 (non plus) and the KPC9612 + and now the Kantronics Kam All Mode. Now I am still looking for the KPC3+

Dx Cluster PI1LAP-1

PI1LAP is Running DXSpider as Cluster Software. With Postgresql as database backend for Web Cluster http://dx.packet-radio.nl

PI1LAP is also connected to the Reverse Beacon Network (RBN). Now it is possible to see (Live) Spots from CW, BEACON, RTTY, PSK, FT8 and FT4.
Connect to PI1LAP-1 (telnet dx.packet-radio.nl 7300) and give the command “help set/skimmer” to get help about the skimmer feed.

The skimmer feed from CW and FT8 / FT4 can be overwhelming. Now there are all kinds of possibilities to filter this to specific spots. Filter help use the command “help filter” on the cluster.

# Possible Filter
To only allow FT4 spots you can use a filter
set/skimmer ft
reject/rbn 1 info ft8
show/filter # Show the rules in the filter
clear/rbn 1 or all # Delete filter rule

If you like Dx spots (just like me) you can go to “telnet dx.packet-radio.nl 7300

See ya on the Cluster.

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…..

Monitor screen from Linbpq BBS.

File compleet.

The same file but compressed.

NinoTnc update

On my very expensive scoop (hi) you see a packet frame @ 1200 Baud received from a station about 50 kilometers away. Looks fine to me.

After updating the Firmware from version V2.35 to V2.81 I see a good increase in the decoded frames.

How to update the Firmware

wget http://tarpn.net/zflash2020oct/tarpnflashinstaller.sh
chmod +x tarpnflashinstaller.sh
./tarpnflashinstaller.sh

Run
tarpnflash usb
* My Ninotnc is connected to ttyACM0.
tarpnflash version ttyACM0
* Is there a newer version available in the dir "ninotnc" you can run.
tarpnflash flash ttyACM0 (version number)
* Now the Firmware is being updated.
* Check if the flash of the firmware went well.
tarpflash version ttyACM0
* Great now running Version v2.81
/dev/ttyACM0 NinoTNC v2.81

I immediately built my second NinoTNC. I am very curious how that works with IL2P mode, Improved Layer 2 Protocol. In the picture below, the two NinoTnc`s are running at 2400 Baud with IL2P mode. Functions perfectly. Now I have some problems with adjusting to 4800 and 9600 Baud. I have to look into this.

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…
