Is this standard Buster release or the special ham radio one that others have been downloading?

To control your 
Ft817 or 857 via cat, use USB adaptator with CP2102. ( i use it here with pi2b)
Connected  to cat port of your ft817 or 857.
If you use wsjtx, the cat and ptt is made via the software.

My first recommendation is too find and join a local radio club. Somebody there should be able to download the necessary software and get an SD card set up for you. Consider Goodwill for your ancillary items. You should be able to get a monitor for under $15, mice and keyboards are a couple bucks each. In fact, you might be able to find a suitable router for under $10, as well as Ethernet cables. A USB sound dongle can be found on Amazon for $5 or so. You will have to lash up a small interface between a GPIO pin and your PTT unless your radio has USB CAT capability. Of course if your radio has a built in sound card, you won't need the sound dongle, just a USB cable (also available at Goodwill) between your radio and the RPi.

Hey Randy,

Personally, I need a bit more info before making recommendations. Not having a router will be a hassle but not a deal breaker. You can plug the cat5 cable into the pi. If you have a tv with an HDMI port, you can use it for the monitor.

1. What type of pi do you have?
2. What type of sound card do you have?

Hi

I think once the KillHotspot has been done it will not reactivate so you will only have the ability

to use the wired lan.

I am going to use the standard Buster load for my Pi4 and hand load the ham apps I want

myself, unless another version of the Dave W3DJS disk image becomes available.

Right now I am not doing anything but getting ready for the family to visit over Christmas

so it is all on hold for now.

Hi

As noted in an earlier post it comes with the Hot spot enabled, so once you can disable it by

entering the KillHotspot command. Note I am not sure that is the correct syntax of the command. Once

the hotspot is killed you can attach a direct lan cable and the internet will work. I have done it.

And others have noted a work around for them, it didn't work for me, maybe I misunderstood

one of the commands, I am not sure. So I am waiting to see if Dave W3DJS will put out another

I hope this helps.

Time for an updated TNC-Pi. I think there is a conflict on one of those ports preventing its use.

The normal way to add a second TNC-pi is to use i2c. But the Pi4 has an extra 4 serial ports that can be enabled if needed so you cold use one of those. The downside is that you can't just stack it on top of the original - you'd have to connect with jumper wires.

As you can see I have the serial addresses ttyS0 and ttyAMA0. I currently have one pi-tnc 2 on my pi 4 and the second one coming probably Saturday to stack on top. After putting the tnc together I tested it and got good tones heard out through my mobile radio on another radio and my yellow DCD light comes on when receiving packet clusters so the tnc appears to be working. But I don’t have any connection to Pat winlink to it because I obviously don’t have something set correctly. I was an ADA software engineer for 11 years but that was 20 years ago. Never wanted to get near Linux and now I need to. Hehe

I don’t have bpq installed, tried and messed everything up using the bpq-config which I now know not to use, which lost my Bluetooth capabilities. So I, fortunately, had backed up my sad card before doing that so I reverted back to the previous ver and got my Bluetooth back

So going forward I believe that I need to use i2c to connect two tnc-pi’s. 

So I guess next step is to try to get bpq installed and working with one tnc without losing Bluetooth

Hello John, Everyone,

Good morning..

This problem arose when Pi models with Bluetooth were introduced. The system
originally uses the main serial port /dev/ttyAMA0 for Bluetooth and assigned
the second serial port /dev/ttyS0 to the Pi Header. This meant that which
port you had to use depended on the model of Pi you were using. This lead to
a lot of confusion and a lot of hacks were published, some of which disabled
Bluetooth and some moved it to the other port.

Many of the guides out there (including mine) disable bluetooth to give the GPIO-connected serial port access to the hardware UART.  This is required as the secondary serial port that the serial port was getting connected to is variably timed and thus is not very reliable for heavier traffic on the serial port.  Here is an extensive thread on the topic:

   https://www.raspberrypi.org/forums/viewtopic.php?f=107&t=138223


The Pi team realised their mistake, and for the past couple of years the
system creates a symbolic link (think alias if you are not familiar with
Linux terminology) /dev/serial0 to whichever port is assigned to the Pi
Header. So applications can use /dev/serial0 for any model of Pi.

This is true only if the serial port is enabled via raspi-config or the user adds "enable_uart=1" in /boot/config.txt.  Once that's done, you'd see the following for a system that has bluetooth and console serial enabled:
--
# ls -la /dev | grep serial
drwxr-xr-x  4 root root          80 Dec 11 07:45 serial
lrwxrwxrwx  1 root root           5 Dec 11 07:45 serial0 -> ttyS0
lrwxrwxrwx  1 root root           7 Dec 11 07:45 serial1 -> ttyAMA
--
If the serial port isn't enabled (even without console services), the symlink for the Bluetooth side won't be created either


Many of the installation instructions for the TNC talk about editing files
cmdline.txt and config.txt. This is no longer necessary, and the suggested
changes are likely to break things.

While I agree that using raspi-config is user friendly, it's only a GUI tool to set the correct parameters in various /boot config files.  There is no magic here but yes, over time, config files can change so the user will need to adapt if things are changed.

David,

Yes, documentation is a bit sparse. As there are no spare pins you need to decide which devices you don't need before enabling any of the new Pi 4 ports.

Was downloading it last night when I went to bed. This morning.. "Download incomplete" I retrace my steps, but having "done this before" just recently getting ALLSTAR LINK images for a repeater node which was a success. Just my 2 cents. Of course if something is corrupting the download or the image downloaded is corrupt, it will never fly.. If you're like me and can only see a little of your neighbor's house in the winter when the leaves are off the trees,  you never know which end of the project is broken..
I will restart download while I assemble my new Touchscreen 7" LCD display in the case it came with that the postman brought this morning  and add a RPI 3B to it.

Re: B+ or 3B+ or 4

Marty Hartwell
 

Hi

Well I am assuming you have a 2 B+, what my other Pi is, and it does run on some Wifi dongles. I have

an old TP-Link slow, and a newer one also is faster. What I have found is that included with the Raspian

Stretch and now Buster does not have the driver for the wifi. I must hook up the eth0 wired and

do the update/upgrade to bring in the needed drivers and what all. Then it works well on wifi.

I haven't yet tried FS8Call or those digital modes yet, but plan on trying them. I do compile and

run most of the Fldigital suite of softwares on it and they work fine, but I expect it might get be

able to be overloaded. I may keep mine for later conversion to a dedicated ham service later.

I have the new Pi 4 with 4GB ram, and plan to try to use it to replace my old laptop. I also will

I think at this price get another for ham use for use in the field. My home is just not suitable

for ham work here. Well I do some VHF operation from the mobile in the drive way now and then.


Good luck

As you can see I have the serial addresses ttyS0 and ttyAMA0. I currently have one pi-tnc 2 on my pi 4 and the second one coming probably Saturday to stack on top. After putting the tnc together I tested it and got good tones heard out through my mobile radio on another radio and my yellow DCD light comes on when receiving packet clusters so the tnc appears to be working. But I don’t have any connection to Pat winlink to it because I obviously don’t have something set correctly. I was an ADA software engineer for 11 years but that was 20 years ago. Never wanted to get near Linux and now I need to. Hehe

I don’t have bpq installed, tried and messed everything up using the bpq-config which I now know not to use, which lost my Bluetooth capabilities. So I, fortunately, had backed up my sad card before doing that so I reverted back to the previous ver and got my Bluetooth back

So going forward I believe that I need to use i2c to connect two tnc-pi’s. 

So I guess next step is to try to get bpq installed and working with one tnc without losing Bluetooth

Hello John, Everyone,

Good morning..

This problem arose when Pi models with Bluetooth were introduced. The system
originally uses the main serial port /dev/ttyAMA0 for Bluetooth and assigned
the second serial port /dev/ttyS0 to the Pi Header. This meant that which
port you had to use depended on the model of Pi you were using. This lead to
a lot of confusion and a lot of hacks were published, some of which disabled
Bluetooth and some moved it to the other port.

Many of the guides out there (including mine) disable bluetooth to give the GPIO-connected serial port access to the hardware UART.  This is required as the secondary serial port that the serial port was getting connected to is variably timed and thus is not very reliable for heavier traffic on the serial port.  Here is an extensive thread on the topic:

   https://www.raspberrypi.org/forums/viewtopic.php?f=107&t=138223


The Pi team realised their mistake, and for the past couple of years the
system creates a symbolic link (think alias if you are not familiar with
Linux terminology) /dev/serial0 to whichever port is assigned to the Pi
Header. So applications can use /dev/serial0 for any model of Pi.

This is true only if the serial port is enabled via raspi-config or the user adds "enable_uart=1" in /boot/config.txt.  Once that's done, you'd see the following for a system that has bluetooth and console serial enabled:
--
# ls -la /dev | grep serial
drwxr-xr-x  4 root root          80 Dec 11 07:45 serial
lrwxrwxrwx  1 root root           5 Dec 11 07:45 serial0 -> ttyS0
lrwxrwxrwx  1 root root           7 Dec 11 07:45 serial1 -> ttyAMA
--
If the serial port isn't enabled (even without console services), the symlink for the Bluetooth side won't be created either


Many of the installation instructions for the TNC talk about editing files
cmdline.txt and config.txt. This is no longer necessary, and the suggested
changes are likely to break things.

While I agree that using raspi-config is user friendly, it's only a GUI tool to set the correct parameters in various /boot config files.  There is no magic here but yes, over time, config files can change so the user will need to adapt if things are changed.

Re: B+ or 3B+ or 4

That is great info Bobby.  Want to set up an absolute minimal station, the power requirements of older boards are better.

I've been running JS8CALL on a RPi-2B for the last two days.  Everything seems to be working well, even with the GPS dongle active. 

I use either my laptop, or cell phone, to remote into the Pi via a Edimax wifi dongle.

I have a Pi B+ (no WiFi).  Has anyone used a B+ (not a 3B+) with WiFi dongle and if so how well does it run (looking to run FS8Call at a minimum)?  Or is a more rewarding path to simple get a Pi 3 or 4?

I know that is vague but what I'm really wondering if the B+ with a WiFi dongle may simply be underpowered for the application.
