And as Marvin said, from the USB port on my laptop to the data connector on the back of the FT-991A. No extra equipment needed. No special cable.?HowardKO6ATESent via the Samsung Galaxy S8+, an AT&T

*Note that you CANNOT achieve the highest speeds VARA-FM is capable of with the built-in '991 sound card. It doesn't have enough audio bandwidth.? To get the full 25,000 baud speed possible on

Go to your web search, Google or whither you use. Type in https://rosmodem.wordpress.com/ That link takes your the main VARA page. Info there will explain everything to you if you take the time to

I use VARA fm and VARA HF on a FT-991A with out any extra equipment. It has its own soundcard so nothing extra needed. I also use it for WinLink. Sent: Tuesday, September 17, 2024 6:43 PM To:

Start by downloading Winlink. You will find links to download VARA on the Winlink site. It’s the best performing soft modem for HF. grant.groups.io@...> wrote:

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

Hi All, I spent 45 minutes looking for a website that sells VARA HF and can't find it.? I don't know who wrote the software, or if there is documentation, or if there is a book. Actually I don't even

The name FM is linked to the? intended? transmission sytem , FM The audio spectrum from Tx <> Rx remains fixed in FM system , hence no 'AFC' needed Hetrodyned systems ie SSB? require exact aligment

Which I have; And it is correctly entered. And I have been using this one for a few years. Suddenly, in Linux Mint, I get this nag though ...been trying for several days to correct the issue. It works

I would disagree. All versions of VARA use OFDM, multiple carriers (tones) each modulated at a slower rate using DPSK. The initial handshake uses dual PSK, so two “tones”. When sending data

VARA HF (used with HF SSB radios) has the ability to alter the audio frequency ?at the sound card level in order to maximize throughput. It does that during the “handshaking” dance when a link is

As others pointed out, there is a drive level right next to the Tune button. But just for future reference, Windows has a volume control that applies to individual apps. This allows you to adjust

On that screen where you press TUNE there is a slider called DRIVE LEVEL! Slide to the left to reduce drive which will reduce ALC. Sliding to the right increases drive which increases ALC. de WA3FIY

Thanks guys, I cannot believe that I missed the obvious!? Adjust the drive level right next to the tune button!? Geez I've been at the computer interfacing too many programs to my FT-891. 73, Terry

Lots of places to adjust transmit out level. But probably the best place so that it does not upset any other programs digital level in on the Vara HF modem program. Go to <settings><Soundcard> Hit the
