Hmmm.. ok.? so your local APRS "digi" is not digpeating?? Have you tried contacting the owner of the machine to let them know?
The local machine is only beaconing, not digipeating. The owner has been notified.
I would recommend to start by setting the output audio from the radio to be 50% and then set the sound device's microphone gain at 50%.? Increase each of them to hopefully no higher than 80% each to make Direwolf happy.? If you
I'll give that a try.
cannot get the level up, there might be a Microphone "boost" or "Auto Gain Control" (AGC) setting in ALSAmixer.? It should be on the sound device's "capture" screen but I've sometimes seen them on the Playback screen for some screwy reason.? I don't have any Sabrient devices here or I would give it a look.? I have had good luck with the Syba units which are very similar.
I didn't any boot or gain controls in alsa mixer.
Ok.. good though just by running Xwindows and XFCE, you've chewing up a lot of RAM.? If this is going to be a dedicated APRS setup, I usually recommend people run the Raspberry Pi OS LITE version to free up as much memory as possible.? Not required but more of a best practice.
If I get to the point of trying to run a dedicated digipeater/igate, I'll get another Pi and strip to cli.
I don't understand.? What do you mean by "not transmit APRS data packet" if Direwolf and Xastir are seemingly beaconing correctly.? When yo say Igate, I assume you mean RF->APRS-IS ... aka a RX-only iGate.? Right?
O can hear data packets on other radios when the system beacons, but when it digipeats, while it does key the Pi and transmits a signal, no data is transmitted. I do have it set up as a RX igate only... I hope :-)
I know it all comes down to budget and it's just a hobby so only you can make the best decision for you.? I will only add that Jpoles are not very good antennas as they don't offer any real gain gain.? I personally like the 2m mono-band CP22W Diamond Antennas for 2m packet and it's only $54!? That said, you're going to have a real issue with stucco dwelling as they create an EXCELLENT RF shield.? Maybe you can talk the landlord into letting you run a coax run to the roof to mount to a roof level sewer vent pipe?? If you can't get that antenna up, your station is only going to hear and be heard in the direction AWAY from the structure.

I live a condo, not an apartment building. I've only been a ham for 10 years and have lived here for 27. I am well aware of my lack of signal propagation... it's a PITA :-)
