Hello Chris,

I'm trying to get Direwolf to transmit on my IC-9700 over a network but I can't figure out how to get the PTT to work.? Is there an easy way to do this?? Currently, I have a PC running Direwolf and the IC-9700 on a lan.? Maybe it is easier to run Direwolf off a raspberry pi with a usb connection to the ic-9700?? I'm open to suggestions.

Direwolf should be able to key your Icom IC9700 no problem by asserting PTT via CAT control.? There are a LOT of materials on the web if you search for "PTT on Icom IC9700 over USB" such as:

??
??
?? etc.

Hello Rick

If so, I cannot explain why Direwolf beacons would work but Direwolf digipeat packets would not.? Can you paste in your whole direwolf.conf file here?? Maybe there is something wrong in there.

The system works with a signalink, but not the USB sound card with the Baofeng on VOX.

Ok.. I think I was confused before.? So make it stupid simple:

?? Permutation #1: using the Signalink USB + Baofeng using electrically asserted PTT WORKS
?? Permutation #2: using the soundcard USB + Baofeng using VOX PTT does NOT work

I now understand only permutation #1 works and permutation #2 does NOT work at all.? Is that correct?? I was previously reading your emails saying that some types of transmissions using Permutation #2 were working which makes no sense.?

Beyond that, there is nothing in your direwolf.conf file that would create such a scenario.

from memory they are 1.8V IOs

I used a NPN and a 2k2 resistor in series, and a 10k to ground I think (10k to ground holds the TX OFF in case of boot up, non configuration etc so the weak pullup doesnt turn on the TX)

Hello Rick,

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.. it's very important to look for those kind of settings and DISABLE them.? To do that in alsamixer, use the left-right curcor keys select the one control like AGC and once selected, hit the "m" key to MUTE the control.? It's kinda screwy but that's how it works.? After that, I highly recommend to use the command "sudo /usr/bin/alsactl store" to save the settings.? Now, in whatever mechanism you use to automatically start up direwolf, you will want to first run ""sudo /usr/bin/alsactl restore" to restore all the correct audio levels.? This is all covered in the Direwolf User Guide.

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 :-)

So when you say "and transmits a signal", you mean the FM frequency goes from static to a clear but silent FM transmission ("dead air) with no modem tones ever being transmitted?? If so, I cannot explain why Direwolf beacons would work but Direwolf digipeat packets would not.? Can you paste in your whole direwolf.conf file here?? Maybe there is something wrong in there.

On a Raspberry, alsamixer will save its settings when you exit alsamixer. Some other Linux distros require running "sudo alsactl store" in a Terminal? after exiting alsamixer to save the new settings.

I'll take another look at alsamixer to see if I missed gain controls.

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

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.

+1.? Maybe +1000.

I believe this Auto-gain is what bit me last year during Field Day.? I had some RF intrusion into the Raspberry Pi's audio dongle, with the net effect that keying up would cause the transmit volume to dive to zero, and apparently beyond.? Simply rebooting the Pi did NOT fix the problem nor could I even go into the Mixer to change it, as the now-negative transmit level apparently caused an internal fault of some kind.? I had to re-flash the entire SD card from a backup copy to restore the Tx audio.? Good for one short transmit, then re-flash again.? If I could catch the volume dive in the Mixer with my mouse before it got to zero, I could keep it from getting locked out.? That got old fast.

After the dust had settled I found the following commands (this from a note to self on my Field Day Pi):

In terminal, to save the current audio file settings as a file use..
"sudo alsactl --file /home/pi/alsa.backup store"

To restore...
"sudo alsactl --file /home/pi/alsa.backup restore"

If you don't need the file and just need to store and restore on the system..

"sudo alsactl store"
"sudo alsactl restore"

I've since repaired the cabling to remove the RF intrusion issue, but left the above file text and backup file in my home directory as a reminder.? Note that the typical TRRS audio dongle has the Mike-in line on the Sleeve connection, which is usually where the cable shield is connected.? Don't do that...

Fingers crossed for some FT-8 contacts this year.?

The Playback "Mic" slider is for playing audio back thru your audio-out that is being recieved on the mic-input... not desirable for ham digi-modes.?

On a Raspberry, alsamixer will save its settings when you exit alsamixer. Some other Linux distros require running "sudo alslctl store" in a Terminal? after exiting alsamixer to save the new settings.

Hello Rick,

I did not do rpi-update, apparently the installer thought? did not have enough HD room

I have reinstalled pulse audio.

I did not compile direwolf, I installed it from the standard repository.

Ok.. got it.

AFAIK, I am the only igate in the area and the one APRS "repeater" in our area is only beaconing, not repeating

Hmmm.. ok.? so your local APRS "digi" is not digpeating?? Have you tried contacting the owner of the machine to let them know?

I have seen the messages from direwolf to try to get the recognized audio level to 50. With he Signalink, it's not too bad to get working, the usb soundcard is a PITA. I haven't been able to get that to work.

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 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 already have Xastir using Open Street Maps on the Pi, bit I rarely use Xastir on the Pi, and so not use it to digipeat.

Ok.. good.

The autostartup is a simple script executed from the session/startup module in XF4CE.

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.

Of the main problems I am having is that they system does not transmit the APRS data packet. Direwolf will beacon position packets, as will Xastir. The system igates.

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?

Also. I am using a 5 watt UV5R, 5 watts into a dual band 450 jpole that is hanging inside my first floor condo which had stucco over wiring for the? outside wall covering.

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.
