Re: Packet Radio Starter Advice

Steve KC1AWV
 

Hi Santiago,

At my home, I run BPQ as a packet switch. On top of that, I run the mail and chat applications built in, and have a telnet port for access to a CMS gateway. For access into the switch, I run soundcard packet (direwolf) and ARDOP. There is a AX/IP/UDP port as well for access via AMPR Net. I use an Alinco DR135TMKIII as the primary radio.

You can use a TNC-Pi, and they're great KISS TNCs. However, it is not a requirement. You can also use a Signalink or a RIGblaster as a soundcard interface if you want to use more than just packet. However, from what I can see, you may be limited to just 1200 baud packet on an FTM-3100, since I do not believe that radio has a 'data' port, which you would need for 9600 baud. The Alinco DR135 and DR735 are capable of 9600 with the data port on the back.

Hi, i'm new to packet radio. I own an analog Yaesu FTM-3100R VHF which i plan to use on packet radio, maybe set up a packet BBS (bulletin board system).

Does the Yaesu FTM-3100R is a good rig for packet? do i need a cable to connect the TNC-Pi to the Yaesu? Does the cable plug in the mic port or usb port? Maybe a minimal starter kit and steps would be nice from people with experience.

RPI-4 wsjt-x install problem

Hamilton Stewart
 

H,

I'm new to RPI-4 (Debian 10 Buster) and using it for Ham radio. I have Ubuntu exprience on a work-station desktop.
I went through the steps in KM4ACK post very carefully. Everything worked except the actual install. 

When I enter:
#install the package again now that dependencies are fixed.
sudo dpkg -i wsjtx_2.1.0_armhf.deb

I get a error "is not a Debian Format archive"  I then extracted it using the Buster tools and still get the same message.

I downloaded the Debian 64 bit version of wsjt-x 2.1.0 from the wsjt-x site and got the same error.

Here is the other response from SCS.  I hope they reconsider in the future but for now, it's very difficult to complain about free.  :-)

Thank you for your inquiry.
Currently there is no plan to release PMON for other systems than Raspberry Pi.
As also stated on the PMON web site, PACTOR-4 will follow in early 2020.

Yaniv, That's quite interesting. Thank you. And I will try that.

Mark, "Anyone have any luck with this configuration?  Alsamixer cannot see the microphone input of the Signalink USB (or another USB sound card on hand).  The audio level is very marginal on the low side with the RX knob turned all the way up."


Re: partition for lubuntu from previous ubuntu

Mark Griffith
 

It should not be that hard.  This is from the Ubuntu 17.04 site:
sudo swapoff /swapfile
sudo rm /swapfile

Create a 2Gb swapfile, set permissions, format it as swap and enable it:

sudo fallocate -l 2g /swapfile  Or /USB1/swapfile or something like that
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
You can put the swapfile wherever you want it.  If you want it on a different filesystem, like a USB drive, just mount it like you would normally do, and put the swapfile there.

Hi Jeff

Thanks for the tips. I haven't decided what I want to do with it so I think your

idea of several google searches will be in order. I think the first order is to get a

low level of use to start with and move on from there.

Re: Ubuntu19.10 & Raspi4

Hi

There was a Ubuntu 1?.something awhile ago the worked on the Raspberry Pi 2. I

tried it out back then and reverted back to the Raspian Jessie I think. So I am not

surprised that 19.10 will be supported on the Raspi4. I will be submitting an order

soon to get a pi4 with 4GB of memory and some other things I haven't yet decided on.

Re: partition for lubuntu from previous ubuntu

Mark Griffith
 

Raspbian, the default OS for the Raspberry Pi, does not use a swap partition, it uses a swap file on the regular file system.  If your memory usage is not too much, it will never swap.  I always create my systems with no swap at all, and in the years I have been using them, I have never encountered a problem.  Of course, these devices are just used to process email and things like that.  No memory intensive video or other type of memory hungry apps.  My applications use less then 20% of the available memory so it never swaps.

However, if you will be using memory intensive applications, you might want to create a swap file.

HI

If this is a Rpi 4 I think I saw a response that swap is not needed, or is a real small amount. So

you may be good to go.

You probably should review the instructions for the pi 4 though, as I have not ordered one yet.

It is in my future though.

≠====================

1) Make sure your USB stick is connected. In a terminal type:
 
sudo blkid
 
It will list all your connected drives. Search for your USB stick you want to use as swap and copy the UUID (everything inside these quotes UUID="XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX").
 
This represents the individual name of your device.
 
Also note the /dev/XXX point of your device.
 
2) Now unmount your device by typing:
 
sudo umount /dev/XXX (where XXX represents your device name)
 
3) Format your USB stick as swap, e.g. by terminal
 
sudo mkswap /dev/XXX (<-- be sure to use the correct device name here or you'll probably end up formatting the wrong drive!)
 
or simply use GParted.
 
4) Now you have to edit your /etc/fstab file, so type
 
gksudo gedit /etc/fstab
 
and enter the following
 
UUID=XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX none swap sw,pri=5 0 0
 
(for all the Xs, use the UUID number you got by typing sudo blkid)
 
5) Now type
 
sudo swapon -a
 
That's it, this should already work

I missed that massage,
I have both RPi3 and RPi4 on buster with Signalink.

If you don't have audio - try to plug the Signalink to your RPi *AFTER* your RPi boot
I found that when you plug everything and then power things up - you won't have audio I/O
