Shortly, I will start doing a series of screen caps every half-hour of my 30 and 40 meters APRS-over-VARA maps.? I will assemble these into an MP4 animated map showing propagation changes on these

VARA and most modern protocols use a variety of modulation and coding schemes based on the current average S:N ratio. The math and coding/decoding are complex but the concept is simple: The higher

This particular one is wide. I connected to it one time with no issues but haven't been able to connect with it or any others? since. I tried to use the test mode in vara....the transmitter seems to

Thanks for your comments. I plan to build in a near future a QMX+ and when its firmware will implement CESSB I will be able to use Vara HF Winlink with it. This closes this thread. 73 - Pierre -

Well, now I feel like a complete idiot again! I got the new sound card in. It is called an AIOB (all-in-one-board) and it's actually like the AIOC, but has separate pads for the various I/O so it is

From the QDX website: "QDX is suitable only for _single tone FSK_ modes, which covers the majority of digital modes in use today. This includes everything in WSJT-X (except MSK144), JS8Call, some

I just tried the Kenwood TS480 setting with the same result: CAT PTT works but the audio level from the PC is not enough to put the QDX in transmission, I might miss an audio level setting in the Vara

I just looked up the exact specifications for VARA HF and there are multiple carriers even with FSK. The QDX can only transmit one tone or frequency at a time. Andrew VK5CV Get Outlook for

Hi Pierre, I haven’t got VARA HF Win Link going yet but have been keeping an eye on it. Putting it on the QDX sounds like fun. I assume that the QDX will only respond appropriately to the VARA FSK

New member in this group, I'm configuring my QRP-Labs QDX with Winlink Express using Vara HF Winlink. There is NO output power from the QDX when I start a transmission with Winlink Express, the

Concerning #1, It could be because the response from the RMS Gateway is sending more data than what the client sends when starting a connection... i.e. an acknowledgment of the first transmission.

On my Windows 11 system, that app is accessed by clicking "More sound settings" from the System > Sound area. ________________________________ Sent: Tuesday, March 4, 2025 1:20 PM To:

Because the other end is not over-driving their transmitter audio-in and clipping/distorting horribly. And they may be using a "data port" connection instead of a mic jack. 1)? VHF/UHF signal

That's very interesting and informative, and explains why the signal I hear from my transmitter sounds so odd. But, I have two questions: 1. Why does the return connect tone from the RMS node sound so
