Irad, Should this also work on 64 bit ARM M1/M2 CPUs found in modern Apple devices? I've tried several how-to's on running Vara/VarAC with Wine. But have absolutely no luck running it on my Apple M1 device. Do you know of anyone having success using Wine on moderen Apple devices? Thanks, Regards, Erik

Not really in normal use, i am however able to replicate the issue when rapidly clicking on the outbox button multiple times.

Hi Irad, I think most / all GPS receivers support the NMEA 0183 format. A (USB) GPS device presents itself as a serial device which then can be polled for the NMEA 0183 formatted messages. There are standard libraries to be found on GitHub to support this format. https://en.wikipedia.org/wiki/NMEA_0183 Thanks for your interest in this request, 73's Erik

Thanks for my first VarAC QSO on 15 Luiz, will be QRV on 15 more often! 73s Erik

Hi Irad, There where no firmware updates until now so i downgraded the rig today. The downgrade also means my rig is set to factory default settings. Unfortunately the result is exactly the same. edit: Also upgraded to VarAC 3.6.6 and latest cat file. When an update is available i will try again.

Yes, i am following your post on Facebook. Until now nobody has confirmed it working correctly with the 1.78 firmware. I'll need to check if i can safely downgrade my rig, i don't want to brick it.

When killing VarAC after a CQ the transceiver stays keyed up. I waited about 10 seconds then started VarAC again. The transceiver stays in TX mode. Repeated this cycle 3 times. Then upgrade to v 3.5 on my laptop, also tested 3 times. Results are the same. The TX is never released. Only way to get the TX to stop is to power down my G90. Next steps are only tested with version 3.5: When the transceiver is in TX mode after a CQ call and i disconnect the CAT cable it remains in TX mode. When i then disconnect the data connection (audio in/out) it remains in TX mode. Other way around, so first disconnect data connection then CAT gives same result. Now for the fun part. When i only connect CAT cable and do NOT connect the data cable (audio in/out) the PTT keying works fine, off course no audio is being transmitted. I've tested 3 full CQ cycles, switching between TX and RX is as expected. As mentioned before, when only connecting the data connection, thus without CAT, switching between RX and TX also works. Which indicates that the G90 enforces VOX when audio is selected from the LINE (in) jack. The radio allows selecting of audio input source, either MIC or LINE. The LINE is the data (din) jack in the back of the rig. I double checked, the VOX setting is disabled. This setting only seems to be used when the audio input is set to MIC. Your effort is surely much appreciated!

In settings, trying PTT ON and OFF works perfectly fine. PTT is toggled instantly when hitting either PTT ON of PTT OFF button. I reverted PortWaitTimeMs to 100 and restarted VarAC before testing just to be sure.

Yes, i did :-)

Unfortunately that did not work. I also tried a value of 500 and even of 1000. Result is the same in all cases.

Hi Chris, I remember having similar issues. What worked for me was explicitly setting write permissions for the user which starts VarAC on the application folder. My assumption was VarAC tries to write something to disk without having proper permissions on the folder. 73 Erik

Marcel, Are you able to work the PI3EHV repeater or have DMR? I would probably be able to help you in Dutch if needed as i have the same setup. When QRV i'm always monitoring the DMR 20431 Talkgroup (Limburg) so give me a call if you would like my help. If your not able to use DMR we could try PI3EHV but we would need to schedule something as i'm normally monitoring local repeaters is my area. Check my e-mail address on my QRZ page if you want to contact me. 73 Erik

Hi Irad, Sorry for the late response. I've tested some further with the G90. When testing PTT ON/OFF it works just fine as expected. When calling CQ the PTT is kept enabled, so that's not how it should be. When using the tuning option in the Vara software i noticed the G90 is also set to TX mode, and stopping a tune cycle does not release the PTT mode. Then i noticed that it works fine as soon as i disconnect my CAT cable. Now the PC is only connected using the sound card interface. Although VOX is disabled the set is keyed-up when i start a tune cycle in the Vara software. This time the PTT is released as soon as i stop the tune cycle. I find it strange my G90 starts transmitting without CAT so i assume this is a software bug or feature in the firmware (v 1.78) of my G90. When the G90 sees audio on the line in of the data jack in the back the set is set to TX. Which is convenient when you leave your CAT cable at home while in the field :-) As a workaround i can leave the CAT cable disconnected and use the magical TX triggering as soon as the Vara software sends audio to the soundcard. The downside is i have no automatic frequency control for QSY. When doing the same kinds of test with Winlink it works just fine in both cases, CAT cable connected or disconnected. Only difference in settings is that i selected the ICOM 7200 as a rig since Winlink has no G90 option. I've tested VarAC with the ICOM 7200 option, but results are the same as with the G90 selected. For other reasons i installed everything on another laptop with a fresh Windows 10 install and made sure the FTDI (usb-serial) drivers where up-to-date. 73 Erik

Hi, Unfortunately it's still not working for my G90. My settings are: And the log shows: 05:42:58 - CMD: CQFRAME PE1PUX 500 05:42:58 - OK 05:42:58 - PENDING 05:42:58 - PTT ON 05:42:58 - BUSY ON 05:43:03 - PTT OFF 05:43:03 - CANCELPENDING 05:43:03 - BUSY OFF 05:43:08 - CMD: CQFRAME PE1PUX 500 05:43:08 - OK 05:43:08 - PENDING 05:43:08 - PTT ON 05:43:08 - BUSY ON 05:43:13 - PTT OFF 05:43:13 - CANCELPENDING 05:43:13 - BUSY OFF 05:43:18 - CMD: CQFRAME PE1PUX 500 05:43:18 - OK 05:43:18 - PENDING 05:43:18 - PTT ON 05:43:18 - BUSY ON 05:43:23 - PTT OFF 05:43:23 - CANCELPENDING 05:43:23 - BUSY OFF The PTT is enabled fine, audio is being transmitted, but the PTT is just never released. Frequency changes are also working fine. I'm running firmware version 1.78 (Jan 19 2022) in my radio. Perhaps other people for which it is working are using an older version of the firmware? The USB Serial device is an FTDI serial adapter, which is working fine for other digital modes apps. I can work using my 7300, but it would be nice to have the G90 working for portable activities. If there is anything i can do in helping with debugging, please let me know!
