I may add to these notes, but a key one was to make sure to give WSJT-X access to the microphone, even when using a USB cable to control the rig. Thanks to K3DCW for the tip.
I presume that you have a checkmark in the box labeled “PortAudio” next to the USB Audio CODEC device selectors. If so, then the only other thing that I can think of is that you haven’t given macOS permission to access your “microphone.” Many of these programs see/treat that USB Audio CODEC as a microphone input and failing to give it access to your “microphone” will cause it to not hear a thing. Go to the Security & Privacy pane and make sure that Fldigi has access to the microphone.
I also have iShowU Audio Capture installed (for OBS screen recording), which I thought might have been the problem. Here are my current working audio settings (Audio Midi Setup).
The rest of the settings described here work out well for connecting the IC-7300 and my MacBook Pro.
To get the gain right in the software, I used the RF Gain knob on the IC-7300.
There is a way to adjust this in the settings but I can’t find it at the moment. It’s the ACC/USB AF Output Level setting under MENU>SET>Connectors (make sure you scroll up and down the menu items as needed). All suggestions are to get the bar in WSJT or JTDX to about 30 dB.
I’ve expanded my search beyond what I introduced in APRS tracker/viewer build concept. Here I will attempt to organize projects some other folks have put together.
This has been sitting in draft mode for several weeks, but I’m pushing it out now and hoping to add more as I learn.
- APRS Trackers (transmitters)
- APRS transceiver bits
- Not APRS, but instructive
- Not APRS, mesh networks
- Meshtastic – Mesh text communicator built on various LoRa boards, includes location information in packets
- Disaster.radio – Mesh text communicator, similar to Meshtastic (I have not done a deep comparison, both look like they use similar hardware).
- QMesh – A LoRa-based Voice Mesh Network
- CellSol – A LoRa “not-quite-mesh” network
- TARPN – Terrestrial Amateur Radio Packet Network – setup requires more hardware, but pretty standardized and probably much more robust than LoRa systems.
- APRS, but on LoRa
Dire Wolf won’t let you save both a daily and single log file of packets received, but if you log daily with LOGDIR, you can write a script that bundles up all the log files and then produces a GPX file of the output. This is useful if you want an idea of the area your digipeater or iGate is covering without trusting to aprs.fi or aprsdirect.com, which only provide the actual path taken and drop duplicate iGated packets.
Simple script for Linux:
# merge log files
sed 1d *.log > log_merged.csv
# convert to gpx
log2gpx log_merged.csv > log_merged.gpx
(sed tip from Linux.com means you don’t need Python or similar)
Make it executable:
chmod +x merge_and_gpx.sh
Run or schedule in cron:
