Hi everyone

[errgh, posted this to the wrong groupsio page earlier. If at first you don't succeed...]
I know it's 'old news' by now, but SUPER shout-out to Jason for all of the hard work he's done to make the BAP experience something that a newb can really dive into.? I've spent the morning getting my Mobilinkd TNC3 & xastir playing together.

It's been a more or less WIN!

Only thing is, there have been some quirks.
For instance, even with the TNC3 'started' using the PAT menu, I notice that it *sometimes goes "down" in the xastir interface control box. When that happens, *sometimes when I click 'start' on the device in interface control it will come back up.... and sometimes not. There have also been a couple of times that clicking on the start tnc3 modem button in the PAT menu... it goes through the scan, and comes back saying it didn't locate a TNC3.?
Wondering if this is something in the Pi ... or if I have a flakey TNC3?? BTW, I'm using Pi3B+.

Regardless, when it's worked, it's been WAY COOL.

I think I may also have to do some 'dialing in' re the TNC3/Mobilinkd settings, as I'm in the Chicago area and seems like I should be able to 'hear' a lot more stations (aka see a lot more things populating on the map) than the 7 or 8 stations that did show up. I'm assuming that's an audio-in tweak in the TNC3 setup app.? For what it's worth, I've now tried it on both my HT (IC-V86) and my packet rig Yaesu FT-2600M....both using roll up J-Pole 20ft up in a tree by my garage. In comparison when running both on APRSDROID, I tend to see/hear more stations.

Thanks again Jason!

You will need to make sure that the TNC levels are configured correctly. This can have an impact on how many stations you are hearing. The mobilinkd team offers an Android app to assist. Check their documentation or their forum /g/mobilinkd/topics

As for the connection in xastir coming/going, it would be helpful to start the connection to the mobilind manually instead of using Pat Menu to start the TNC connection. This is a bit more of a pain but would allow you to see if it is the connection between the Pi/Mobilinkd that is becoming unstable or the connection between Xastir/Mobilinkd. In other words, when the interface shows either down or error in xastir, does the bluetooth connection between the Pi and the Mobilnkd still exist?

Hey Jason
Yeah, I know that the 'correct levels' settings within the TNC3 app need to be set appropriately..... so far, tho, my experience is that this at times seems to border on magic/alchemy. Getting the output power level correctly with just the naked ear is a roll of the dice. In the absence of sophisticated electronic equipment, I've downloaded a decibel app for my phone that detects differences in noise. And in terms of getting the input level set.... I've discovered that when I'm using my FT-2600M with its data-out jack, I can't get the LEDs to just 'tickle' the max. Input level is pegged to the max even when both sliders are turned all the way down. When I use the auto-adjust feature it usually leaves the gain at 0, but often sets the twist between 3 and 5 db. I'm assuming that it's the INPUT settings (along with my antenna) that determine how well I 'hear' other beacons.?
In the end I'm not really sure that my TNC3 is the final solution, especially for use with my FT-2600M mobile rig.

Which brings me to another topic.
But I'll post that as a separate item.

73!
