Have you tried VSPE for your virtual pair?Yes, same thing basically.? VSPE took some fumbling since there is no documentation.? ?I followed a couple videos for configuration.? With VSPE nothing appears in device manager. ?
Update, I found out it works even though it doesn't appear in device manager.? I've not found a way to have 2 different physical ports configured at the same time, to different virtual ports.? Maybe 2 separate instances running concurrently?? |

VARA on virtual com port??
I've been battling trying to get this working for a while, hoping someone can give some advice. Using a FT-991/Win10 and Winlink VARA FM p2p works fine.? The problem is when I throw Win4Yaesu into the mix with com0com v.2.2.2.? The virtual com ports appear in my device manager (com8<-->com9) but they do not appear in the VARA com port setup. Any ideas would be greatly appreciated. |

That's true for all HF digital modes, including VARA HF.?
?
It's probably also true for VARA FM operation, on VHF/UHF bands, on typical radio circuits in good to very good conditions.
?
However, Stephen WA8LMF has it right... the transmit audio bandwidth of the built-in USB rig-interface system on FT-991(A) isn't sufficient for full-throughput VARA FM WIDE operation.
?
If you want to be able to achieve 22kbps or better throughput on registered (licensed) VARA FM WIDE sessions over optimum links, using the FT-991(A), this is only possible with an external rig-interface device, through the mini-DIN6 connector on the back of the radio.
?
Suitable external rig-interface devices include the Masters Communications DRA- series devices, a SignaLink USB device (new model, with black transformers), or a digiRig Mobile device.

I want to start out by saying you don't have to buy the VARA HF (software radio-modem) program. A fully-functional (but moderately speed-limited) copy of VARA HF can be downloaded and used, for free, from the developer, Jose Nieto Ros, at . The latest version of the VARA HF program is also available from the download page on the Winlink website, at .?
?
What is it?... VARA HF is a Windows program that works in conjunction with "rig-interface device" (USB sound-card, and PTT) hardware, to implement a software radio-modem that can be used for digital communications between similarly-equipped HF radio stations. Many popular HF transceivers have built-in "rig-interface device" functionality. If the transceiver doesn't have this functionality, an external rig-interface device, such as the Tigertronics "SignaLink USB", a "digiRig Mobile" device, or a Masters Communications DRA- series device, can meet this need.
?
The VARA HF radio-modem program is optimized for the operation using SSB modulation, and compensating for the signal-quality "impairments" that result from the propagation effects and distances inherent in HF operation. A separate "VARA FM" version is optimized for Frequency Modulation, and the signal-quality characteristics common to FM operation on VHF/UHF bands.
?
VARA HF software, when used with a rig-interface device, is functionally equivalent to having a (very expensive) stand-alone PACTOR modem. VARA FM, used with a rig-interface device, is functionally equivalent to (but much faster than) using a standalone "Packet" TNC (Terminal Node Controller)
?
Once you've installed the VARA HF and/or VARA FM program, you have the option of paying for a software registration key. One registration key will apply to multiple installations of either (or both) programs. Applying the registration key will approximately double the maximum possible throughput for either VARA HF or VARA FM, and enables a few additional features on the VARA FM program.
?
With a registration key (i.e licensed), VARA HF can achieve throughputs comparable to what's possible with a PACTOR 3 radio modem. New PACTOR modems (available only from the German manufacturer SCS) cost more than $1000. Unregistered VARA HF offers half that speed, which is much higher than offered with any other HF "software radio-modem" technology supported by the Winlink Express radio-email client program.
?
Maximum throughput for unregistered (unlicensed) VARA FM, in 'WIDE' mode under optimum conditions, is about 11kbps. This is more than 30 times faster than the best throughput achievable using "Packet" technology. And, VARA FM continues to offer high throughputs under conditions where packet is unusable. Under optimum conditions, registered VARA FM has approximately double the maximum throughput of unregistered VARA FM.

Re: Windows USB Drivers for VARA and DRA-50 on Yaesu FT-991A
开云体育Grant, I see others have answered your questions on where to find the software and instructions. Once you get your software set up, contact me and I will send you an Excel file showing the FT-991A menu settings that I use to get VARA-HF to work. It also will show settings for VARA-FM and VARA C. Be patient. It is a great way to communicate. I just went through this learning curve over the last 6 months. Once you get it working, let's try to use it to contact each other. Cheers,?
