On what network? TGIF? BRANDMEISTER?

Hey, Irad... guess what? After experience that oddness for several days, it stopped! Had it on both my Win 11 mini pc's. Maybe a microsoft update was the problem? 73, Joe

I'm not an expert, but based on many years of using all these programs, I don't think what you suggest is possible. VarAC uses the VARA-HF software modem exclusively. To use FT8, and JS8CALL, the VARA-HF modem would have to be stopped, then FT8 or JS8CALL would have to be started and interfaced with VarAC. Once done with FT8 or JS8CALL, then those programs would have to be stopped and the VARA-HF software modem re-loaded and interfaced to VarAC. The above does not even begin to touch other issues, like setting filter widths for receive and transmit, and keeping receive and transmit audio levels consistant. 73 Joe

In the 3 years I've been running VarAC, and over several years using JS8CALL, and other "keyboard" modes, it's been my observation that it's getting harder and harder to find folks willing to chat. Maybe it's because most hams don't feel comfortable banging away on a keyboard? I learned to touch type in high school, way too many years ago, and then held a job that was computer based for 30 years at the FL DOT, so keyboard use is no problem, and actually the way I prefer to chat on ham radio. I don't even know where the mic for my 7300 is, HI. The overall trend recently has been for a gradual increas in folks calling CQ, so that's encouraging. 73

Since VarAC uses the VARA-HF modem, it is a one-on-one mode, and (unless you and the station you want to chat with, are using the BROADCAST function) it's not possible to join an "ongoing conversation". The only way to monitor traffic from stations NOT in BROADCAST mode, is to run a separate copy of the VARA-HF modem, and use that to see traffic on a given slot. Monitoring this way requires reception of a rather strong signal, and there is no error checking, so many times you will not decode text from the stations in QSO on a slot

I used to run Log4OM (with radio interface not enabled) and FLDIGI/WSJTX/VARAC etc without problems. I used those programs to do everything with the 7300. You will need to update your Silicon Labs driver, as the CP210x 32 bit version will not run in Windows 11. I've included a link to the Silicon Labs site which will allow you to access the driver you need. Download the CP210x driver, unzip it, and then choose the 64 bit version and install it. https://www.silabs.com/developers/usb-to-uart-bridge-vcp-drivers?tab=downloads

Thanks for the comment, Irad. I guess I must be loosing my marbles (what few I have left) as I remember that notification being higher up in that window. I'll switch to the Tabbed view today. 73, Joe

I'm not sure how you ended up with that receiver noise UN-centered. Make sure you have your "twin Bandpass Filter" turned off, and have a 600 Hz filter set in the 7300. You can do this using one of the filter settings in the VarAC_cat_commands file that runs when you first start the program.

Why not just make it an OPTION in configuration, to have the time of your choice shown?

On my 7300, I set a filter to 500 Hz, and choose the option in vara-hf to allow 500 Hz connections, and it's. Centered automatically

What filter width are you using? Here's what VARA-HF should look like with the filter at 600 Hz. 73, Joe

I must be dense... does checking the "unattended links" checkbox PERMIT or PROHIBIT unattended links? I've read the paragraph over several times, and am just not sure how this option works.

Right click on the word with a red line under it, then click on the correctly spelled word

VarAC uses the VARA protocol, created by EA7HVK, by using his software modem...VARA HF or VARA FM for VHF comms. The mode is a one-to-one ARQ system, and only two stations can be in s QSO at a time. VarAC adds many features, including the ability for a roundtable or net using broadcasts.

I don't know if it's possible, but to me, a better solution would be to supress the message alltogether.

All that you say is true, but in my case, all I have room for is a vertical, and no means to support wire antennas. I've got a line isolator at the antenna, and am thinking of getting another one to use just before the antenna input on the rig. The one I installed DID seem to make a slight difference in noise, and also really helped with RFI too.

In my case, I have a nearly constant S6 noise level on 20, and worse reception on 30. I think it's astounding that the VARA-HF software modem works as well as it does! Thanks for the well thought out post, Gary.

After connecting, and choosing a slot (or custom freq) select "send file". At that point, you'll see a folder with your files and pictures (the path has to be set in the "rig control and configurations" screen in "Settings". Select the picture or file you want to send, then adjust the sliders for resolution and quality, while also watching the resulting file size, to get the best compromise for file size and quality. On HF, smaller is better, unless you have a REALLY GOOD path.

The "incoming connection request " means that the call has not been decoded. Just sit tight till it appears, or the link fails.

Perhaps I'm stating the obvious, but it you type in the callsign to the right of CONNECT "box", then you must also click on the bluer CONNECT BUTTON, below the "frequency schedule" box to initiate the calling sequence. Your station will try to connect to the callsign you typed in.
