Even on a perfect channel, VARA will only switch to higher speeds if there is a sufficiently large amount of data waiting to be sent. Try to send a text file or a picture. When I did a test on 10m with a local Winlink RMS, VARA did not go higher than level 12 of 16. So there might be other factors limiting maximum speed, probably related to your rig. 73, Markus HB9BRJ

See section "How complex callsigns work?" in the VarAC manual. Markus HB9BRJ

No virus warning here. Running latest Windows 11 22H2 (OS build 22621.2283) and Security Intelligence Update for Microsoft Defender Antivirus KB2267602 (Version 1.397.1574.0) 73, Markus HB9BRJ

Working fine here using latest Chrome browser. The "Download latest CAT commands file" button will take you to a forum message and from there to Google drive. Markus HB9BRJ

No need to edit ADIF log. In TQSL Preferences > ADIF Modes, add this mapping:

Probably your main sound device goes into sleep mode. Change the Windows power options or use a utility like https://www.softwareok.com/?seite=Microsoft/DontSleep while VarAC is running.

Hi Dave, Please look at this case which was solved by changing driver versions: https://www.dell.com/community/Latitude/new-Dell-9430-Win11-Audio-audiodg-exe-crashes-using-Microsoft/td-p/8232803 73, Markus HB9BRJ

Dave, here are two ideas: - inspect VARAHF.log - Event Viewer > Windows Logs > Application (scroll back to the time of the event) You reported it happened while in a QSO, but your VARA status line indicates the connection has been lost and a reconnect is going on. 73, Markus HB9BRJ

Dave, got the same update yesterday. The "winver" cmd shows 22H2 build 22621.1555. No problems so far. What I experienced a few times over the last months is a link "deadlock": Good signals, data to send, but VARA modem remains inactive. Finally this leads to a timeout and disconnect. No crashed or frozen apps, only the data flow is stopped. 73, Markus HB9BRJ

As stated in an earlier post, Yaesu FT-1000MP Mark-V needs 2 stop bits. Your OmniRig screenshot shows 1 stop bit. Use the OmniRig Client to debug CAT: http://dxatlas.com/omnirig/Files/Client.zip

Problem solved in VarAC 7.0.8: Narrator works without admin privileges under Windows 11 22H2. Thanks Irad! 🙂

Check your locator entries in WSJT-X, fldigi, Winlink Express...

Fully agree with you Andre! Also I am trying to activate 30m VarAC. PSKreporter shows around a dozen stations in the past 24 hours, but the chance of meeting one another on the time axis is very low. I remember the good old times when I had PACTOR contacts to VK/ZL almost daily, running 25W into a simple vertical antenna. Let's continue to activate this wonderful band! 73, Markus HB9BRJ / AE6MG

Fully agree Joe! Have experienced it multiple times, also with stable, non-marginal links. Here is my latest example: VarAC.log: 05/02/2023 14:04:51 - Switching to Slot 13 05/02/2023 14:04:51 - Connecting K1FM 05/02/2023 14:05:39 - Connected to K1FM 05/02/2023 14:05:52 - PSKReporter self report: Logged successfully 05/02/2023 14:05:52 - PSKReporter: Sending accumulated records 05/02/2023 14:06:59 - Disconnected from K1FM VARAHF.log: 2023-02-05 14:04:51 Connecting to K1FM... 1/15 2023-02-05 14:05:39 Connected to K1FM VARA HF v4.7.2 2023-02-05 14:06:59 K1FM Average S/N: -8.2 dB 2023-02-05 14:06:59 Disconnected (Timeout) TX: 0 Bytes (Max: 0 bps) RX: 10 Bytes (Max: 88 bps) Session Time: 01:20 73, Markus HB9BRJ

Found a workaround 😀: Run VarAC with administrative rights. 73, Markus HB9BRJ

Not necessary to wait for a narrator activity. It is sufficient to enter settings and check "Narrate CQ". Without even saving the modified settings, VarAC crashes immediately. Nothing to see in log file. Windows 11 Professional 22H2 22621.1194. When replacing VarAC.exe V6.6.13 by V6.4.15, everything is working fine again.

Sorry, neither a message on screen nor an entry in my debug log.

Erich you must upgrade your VARA installation to 4.6.9 as per the announcement on the VarAC homepage. Your log shows VARA 4.6.8. Hope this helps! Markus HB9BRJ

Tried to connect you at 08:12z but no success. Solar parameters are not good today but nevertheless I will try again during next couple of hours. Markus HB9BRJ

Trying again today. Nothing on 10m so far but nice grey line reports on 20m at 0745 UTC.
