I don't own the G90 so hopefully an actual owner will jump in here. From my experience with other radios, I would think you should use the USB-FTDI option. There may be something that you need to configure/enable in the radio menus for everything to work correctly.

--

The RS-BA1 software is Windows only. If you want to start with the Pi, I would recommend a plain USB cable between the Pi and the radio. This single cable will handle CAT (rig control), DATA, and GPS. Get familiar with that setup and then branch out to learn more about your radio/computer combination.

Brand new green tech here. ?I'm chasing my General motivated for broader digital capacity within the EmComm rabbit hole.

I bought the IC-705 because my background is backpacking and bushcraft and my goal is QRP EmComm. ?I did not select it with a full understanding of how feature rich it is.

As I move towards FT-8, JS8CALL, and WINLINK... am I understanding my computer connectivity options correctly?

USB Wired Connection:

Option 1: ?Run Pi with Pat Winlink. ?$140 RS-BA1 software.

Option 2: ?Run Mac machine with Pat Winlink. ?$100 SDR-Control software.

Option 3 - Run Windows machine with Winlink Express. ?$140 RS-BA1 software.

Wireless Connection:

Option 4: ?Run Pi with Pat Winlink. ?$140 Rs-BA1 software. ?WLAN connect direct to IC-705.

Option 5: ?Run Mac machine with Pat Winlink. ?$50 SDR-Control software for iPad. ?WLAN connect direct to IC-705. ?(This seems like the cheapest, cleanest solution if you have an iPad)

Option 6: ?Run Windows machine with Winlink Express. ?$140 RS-BA1 software for tablet. ?WLAN connect direct to IC-705.

Bluetooth does not play a part?

I also have a TNC3. ?$13 Icom TNC cable and add phones for WOAD options? ?Is a TNC the only way to connect a phone?

I'm very fortunate that I have more gear than know-how currently. ?I was prompted to purchase before inventory issues became a thing. ?Any software or devices I am overlooking?

Currently playing with 2m/70cm on a signal stick antenna - 10m on a home-brew dipole.

I have an 20-30-40 end-fed for General options.

Enough questions in one question? ?:) ?GRATEFUL for any wisdom!

KQ4DMR (on Winlink too)

Hi KM4ACK et al.,

Thanks for all the great videos. I just ran build-a-pi on my Pi 3 B+. Worked great. Now trying to set up flrig according to your instructions, but can't seem to figure out which COM port to use. I have both the USB sound card and the data cable plugged into a USB hub, which is plugged into the pi. In the Flrig dropdown list, there's only one listed as serial, which doesn't seem to work, and then about 50 other options that start with "tty." (See attached photo) Is there a way to determine which port is right? I've tried almost all of them with no success.?

Thanks to all for your help!

The really annoying part is that you have to make the adjustments every time you open FT8/JS8. I have never figured out a way to make it stick once the app is closed.

You have to update your grid square in Pat before it will show you the new RMS stations. You can do it in Pat Menu->Manage Pat Winlink. From there, you have two options. GPS update or manual update. Once you do one of those, the RMS stations should update in the pat mailbox.

Now, if you want to update the list in Pat Menu, then choose Find Winlink Gateways from the main screen. Then choose Recalculate Distance and Bearings. The only time you really need to use this option is if you want to add an alias or if you plan to use the Pat Auto Connect feature in Pat Menu.

If I use PAT Menu to Stop Modems then to Start Packet Modem, then I get one more connection, with subsequent attempts failing as above.

This is a known bug in the ax25 stack in Linux. Right now, the only option is to stop the modem before attempting a second connection.

Glad to hear that Pat Menu is working as it should :-) Pat Menu was written to help simplify the Winlink connection process in Linux. It starts everything in the correct order in the background instead of the operator having to start each item manually.

Further update, Monday mid-day:

If, instead of running "direwolf -p" I use the BAP PAT menu to "Start Packet Modem," then I'm able from PAT to connect over the air (!!!):


But that works only one time. Second and subsequent connect attempts yield the following error:

Thanks Jason and anyone else following.

1. As requested, here is the current output from arecord -l (it is unchanged from what I wrote earlier in this thread):

I can speak from experience.? Icom and GPS/gpsd have "issues."? I run an Icom IC-7200 (and a Yaesu FT-891).? In the config file gpsd set AUTOCONNECT to FALSE.? Find out which USB port your Icom rig is using and make sure that this USB port is deleted or commented out (better) in the config file gpsd.? Shutdown gpsd and restart, or reboot the pi.? This has worked for me.? FLRIG, soundcard and all digital apps? function as they should.?

I traveled from EM64ko (North Alabama) to EM64kl (South Alabama), but the RMS list was only presenting stations near my EM64ko QTH.? The GPS was working great, but Pat wasn't using it to present the local RMS stations.? Any thoughts?
Thanks,

I assume you are referring to FT8? The example I show below is from JS8Call with Pulse Audio but it should work the same in FT8. Note the volume control is called "QTPulseAudio" and only shows up after opening FT8/JS8Call. On my Pi using the 705, adjusting this slider will reduce the incoming audio levels (See images below). It works the same for the 891 using a sabrent sound card.

Run this command and post the results please:
arecord -l

This will output the sound card number. Just want to verify that it's 3,0. By chance did you install the GPS software with BAP? If so, also run the following:
cat /etc/default/gpsd

and post the results. This will show the settings being used for the GPS. Seems weird but more than once the GPS has interfered with the sound card on an Icom rig.

The reason I ask.. Using this as a reference:


GPIO 18 also has special functions (PCM CLK)
whereas ( example GPIO 17) other GPIO pins are just generic.??

Does PPS need the CLK function of GPIO 18?
