I have this working: A Raspberry Pi with a TT4 connected by a USB cable.? I am using Pat software, and I learned a lit about it from KM4ACK's videos, and also from https://www.k0swe.radio/pipat.? I followed KM4ACK's
"Easy as Pi Access Point WIFI Hotspot"
"Raspberry Pi Hotspot Tools"
"Install Winlink on Raspberry Pi 4 Part 1 2019"
?
and this: https://groups.google.com/forum/#!topic/pat-users/vujSjYpkSEY
?
This was also helpful: https://github.com/la5nta/pat/wiki/AX25-Linux
?
I also installed KM4ACK's
"Install the Emergency Email Server"
as I am doing this to prepare for emergency support.
?
If you install a GPS, I found that in /etc/default/gpsd, I needed to set USBAUTO="false" and DEVICES= "dev/ttyUSB1"
otherwise, gpsd interfered with ax.25 connecting with the TT4 on /dev/ttyUSB0

I am going down this same path. For Raspberry Pi instructions search KM4ACK. He has a site with instructions as well as YouTube videos. That should get you running your RPI with a simple GPS, Xastir and Pat. Focus on getting that configured the way you want it first.

The easiest way to connect a TT4 to a Raspberry Pi is definitely through a USB to RS232 (Serial) adaptor.?
As for the particulars about the Pi applications and getting them to connect to the device, I have no knowledge.? That should be in the documentation.? The WIndows versions would use COM#: where Raspian (Pi OS) would use something like /dev/ttyAMA# (hardware port which is not compatible without a level shifter), /dev/ttyS# (most laptop or desktop hardware ports) or /dev/ttyUSB# (USB adaptors).
When you connect the USB to RS232 into the Pi, you will find a new file called something like /dev/ttyUSB# (where # is the number of the USB device).? Because of the "plug-and-play" and assignment at plug-in, the USB device can change.
If you are familiar with Linux udev rules, you can create a udev rule to assign a shortcut with a more familiar name (like /dev/tt4) which will always point to the proper device and can be used in the setup.? Post again if you'd like some help with this.

Is it as easy as plugging the TT4 into the Pi using a USB to serial cable and then using AX.25 to connect them together?? Or is there a better way?
There is this really nice solution for this, PiGate, but it depends on the TNC-Pi which is no longer available so I am looking for an alternative.

Re: How DO You Set Up a Byonics TT4A as an I-Gate
Should be pretty much the same for either. TT4 should be in KISS mode (as with most APRS clients).
Difference will be in how you address the port: ? ?/dev/ttyUSB#? ?if using a USB adapter
? If using the hardware port, you MUST level shift it, or remove the level shifting from within the device (non-built only).? If that is your intent, repost.? The device is a bit different name, and level shifting isn't straight forward because the Pi is 3.3v and not even 5v tolerant.

I need to do a coverage study for low-band VHF (non ham) for the road department in a large county, 6000 square miles.
I think I can cover it from one site in the middle of the county.? My understanding is that the Red Cross covers all of California from five sites.? I'm looking at a mobile?on 45.36 MHz, with a TinyTrak, talking to a base on the mountain with the audio relayed
to the office.? Not sure what to do at that end.? Maybe somehow record a serial data stream and then break it up into a spreadsheet, and then dump that into a GIS program.? I'm casting about for ideas on what hardware or software to use on that end.? Also
any ideas for anything better than just plain signal / no signal.? Can anyone shed light into this corner?

Bear,
So the plan is basically a propagation study? I think it is unlikely that you will just be able to re-transmit audio from your mountaintop receiver and know with any certainty whether your real-life packets would be decodable. I suggest using a digipeater receiving on your Mountain top ( Unless you have an Internet connection up there) splitting?your TX and RX frequencies so that you can easily distinguish digipeated signals from original tracker/data transmitters. If you do have an internet connection on the repeater sight, you could set up an I-Gate, and send your data to the APRS-IS, so you could use aprs.fi or other sights to log your tracking data on maps-probably the way you want to see them. If you can't set up a digipeater on the mountain, and have to rely on your voice channel, you may want to consider sending your original packets at 300 Baud. This will eat more bandwidth, but will effectively double your range, and the packets will have a better chance of getting through your mountaintop receiver without getting eaten up by the voice formant filters in your radios.
Naturally, it would be very naughty to set up any cross-radio service connection that would bleed your Land mobile traffic into the Amateur Radio Network, so if you keep your traffic on your frequency, and take care to make sure that your data is not being digipeated? onto the Ham bands, you can take advantage of the extant network.
The other options for your final receiver sight are to use a mapping program on a PC, connected to a receiver. APRSIS32, APRSDROID, etc would allow you to have a receiver with mapping and logging, without relying on the internet.?
I suppose I don't have to mention that propagation in the sub-six meter band will be subject to a lot of variables??

I use minicom.? Takes a but if gerting used to, but does the job.? Lots of <ctrl>a functions.? I tend to do? <ctrl>a z and it gives an explanation of the options which you can access from that screen.
After awhile, you get the keystrokes memorized.

Re: How DO You Set Up a Byonics TT4A as an I-Gate Station?
You already have a TT4, why would you buy a TNCPi? No APRS client (APRX included) cares what type of TNC you use.?
I have used APRX with a MTT4B on a Pi.?
?? My setup was the Pi Zero W and the MTT4b connected to the UART port (GPIO14 & GPIO15).?
?? The MTT4's Max232 chip was removed with resistors to drop the voltage (Pi Rx pin to ~3.3 V).?? ?? The MTT4B used 12V power because it has the built in radio.?
If you used a straight TT4, it could be powered by the Pi.??
I believe the TT4 requires 5V for the procesor speed, and still require the resistors for the voltage translation. Option 2 would be to power the TT4 4 from the normal source (same as radio) and used Pin-4? power for the Pi. ? PLEASE CHECK POWER requirements first.
If you had the Bluetooth Pi (Pi 3 or Zero W), and the Bluetooth attachment on the TT4 (or MTT4), you could have things running in no Time.? The BT would replaced the serial interface - no resistors required.? The 2 pieces wouldn't need to be connected, but it is
??
It really is configuration.

Might be good practice to try it with your present laptop, especially if you're not concerned with a mapping display.? Just sending decoded APRS data obtained from RF to the internet servers is not a complex task and any PC and even microcontrollers can do that. ____________________________________ On Monday, January 20, 2020, 12:56:38 AM EST, Dave / KL7BX <bearskinrugmaker@...> wrote: My next goal, now that I finally got it up & running as a Digi, is to upgrade it to a full I-gate setup.?
