Re: Issue with aLC on vara hf
This is all very interesting. ?I am operating with the Yaesu FTdx10. ?When on FT8 with WSJT X, I am able to adjust the ALC to wherever I wish it tore. ?Generally, I keep it below half but above 1/3 and that seems to be the best area. ?On the other hand, with vara HF I am not able to adjust the ALC very well. ?It just remains around 3/4 give or take no matter what I do.

Re: VARA HF Disconnects Before Messages Are Sent
Hi Chris,
Indeed, the ham radio hobby can be quite overwhelming.? I work for a living in a non electronics business, and so it has taken years in some cases for me to actually getting around to understand something.? Trying to do something is the best, if not most frustrating, way of developing understanding.? This takes time.
YouTube can be your friend.? I'd recommend Wavetalkers channel.
Also, do a search through the groups.io channels.? There are many cases where folks have done very good explanations of various radios, interfaces, settings, etc.
For immediate gratification, I'd recommend a local Elmer or three who can assist.

Re: Issue with aLC on vara hf
The recommended ALC level for digital modes will vary by radio manufacturer and possibly by model.? The manual that comes with the radio should be your 'bible' for setting ALC levels for digital modes on that radio.
For example, for Elecraft radios, the recommended ALC level for digital modes is a solid 4 bars, with the 5th bar flickering.? Anything much less than that will cause the radio to 'power seek' (wander up and down).
Again, please ignore anyone that tells you what the 'correct' ALC level is and ALWAYS refer to your radio manual for the proper level.

Re: VARA HF Disconnects Before Messages Are Sent
Ken, ? “Once you learn how to use it, and how to interpret the info, it can be very useful!” ? I checked the link and it is overwhelming. Do you know of a good beginner resource that one could use in conjunction with it to understand the information it is providing and some context into how that information can be pressed into useful service? ? 73 and thanks in advance!

Adjusting this should bring your ALC right into the sweet spot.

There is also the legacy Windows 10 sound control panel applet still in Windows 11. Some people find that easier to use. Both accomplish the same task.

Re: Issue with aLC on vara hf
Does that radio have a soundcard interface built in?
Yes, it does. It's hard to tell from the manual whether it does or not, but it does.
