Dang! Now I get it. I've been winging this for a while; it was clear as mud. Your explanations cleared the muddy waters. Thanks so much!
So glad it is all coming together now!!
MJ; Thank you, thank you. Simple and informative very easy for this old ham to understand. Took notes to help while operating.
Glad it was helpful! Thanks for taking the time to post this. This stuff can be tricky but once you get your settings correct, most of the apps work pretty well.
MJ Just an FYI... when using JS8Call, if you hit the RX button on the top right, it will start you receiving and your meter on the bottom left will togggle on. Good job on tackling setting sound settings. You did show all four of the places that folks have to address. Well done. Rick, K4REF
Good to know Rick, for some reason I don't remember having this issue before. Then again my mind is not what it use to be either LOL.... Thanks so much for making this clear. Really appreciate you taking the time to post this!!
This Channel is outstanding!
Thanks for the kind words!!
Had to reference this video again. Got my old-new FT897 all up and running now. Thanks!
Great to hear! Working on my FT-879 in a mobile setup now. FUN!!
Thank you MJ for another great video.
So nice of you to take the time to let me know.
Thanks for the great tutorial! Setting the proper scale in FLDigi was very helpful; I was wondering my I was showing only -db.
Hey Gary, this was eye opening to me too. There are so many moving pieces that no one really talks about in HF Digital. I am glad you saw the importance too. Thanks again my friend to taking the time to post. Always learning :-)
Great video! Very helpful!
Glad it was helpful! As I learn this stuff, I pass it on. Next two videos - "Learning to use a thumb drive to launch your apps" (little to no syncing issues when using multiple computers) & "Digital apps in the VHF / FM world" (local FM digital app comms)
@@hamradiomadesimple Nice! Can’t wait to see the upcoming content!
MJ, Another great video. Answered many questions I have concerning audio adjustments and radio and software settings. Very very thorough presentation. I know you are putting a lot of work into these videos. They are of great value.
Looking at your future video subject plans they are mouth watering for me and I can’t waite. Thank you for you wonderful work. You are living up to your channel’s title. Also, like the way you have the VaraAc ‘s window arrangement and color scheme set.
In regard to your video on VaraAc, I’ve watch it multiple times to help get set up on that amazing app.
Thanks again, Daniel KD2ZTX
Just replied to your winlink email :-)
Wow, MJ , after watching your last video last week I went back to review others and I was suprised to see @ 11:13 you have both Capture and Playback running (USB Audio Codec)!. You are so right about " how they can change" as on both my HP Envy laptops, Microsoft Windows 11 has somehow switched from USB Codec to Realtek and now I am dead in the water using JS8Call as it will not work with Realtek. I am running a suboptimal (due to space limitations even though the inverted V apex is 60 ft high) a 7 band Buckmaster 10-80M OCFD and a KX3 with KPA 100 which requires a SignaLink sound card. I couldn't make any SSB QSO's on 20 or 40 due to poor TX (although I can Rx quite a few Dxs), and so I tried JS8Call which had been working until the Realtek suddenly appeared and Codec vanished.
I have tried everything to find the USB Codec driver, tried every UA-cam video tutorial, gone to HP to see if I could get the Codec, but for the life of me, nothing has worked. I can not find the USB Codec drivers for the input/output modulation or the notification Codec sound cards. Everything else works on the computers, so going nuclear with a wipe of the whole computer and reinstallation of Windows will not provide a long term solution, only having the sacred USB Codec driver always on standby backup makes any sense.
I just don't know enough about computers and radios to know whom to be pissed off the most at the moment, but I think it is Microsoft. I'm surprised that Elecraft hasn't devised an internal sound card for its KX3 or that JS8Call seemingly relies on a very hard to find USB Codec sound card instead of the ubiquitous Realtek.
But I am not imagining this.

Not to be paranoid, but it wouldn't surprise me if Microsoft has deliberately switched USB Codec to Realtek to foil Ham radio operators!
You mention emailing instructions and setups to viewers. If you do have a file of that Codec and it is not a hassle, could you e-mail it to me at my QRZ.com address? I would really appreciate it. I know you have a lot of stress with your upcoming surgery, and quite frankly I'm amazed that you are still at this.
Best wishes and 73's

One last thing I forgot to mention in the email. Delete the existing drivers, reboot the computer. Then download a different driver version. I found that when you don't reboot, the old driver hangs around. You are doing all the right stuff and don't give up!!
I wanna get my beginner license but want to find a good on line study course. Don't even know where to start to find one.
Here is a link to a video I did on getting your Ham Radio License: ua-cam.com/video/sil8lMibS00/v-deo.html
Make sure you go to my channel main page. I have a lot of videos for new operators. It will help you understand many of the principles of ham radio. Once you watch it, I am sure I will hear from you again :-)
I was told that on the Xiegu G90 you wanted your ALC at just below 100 say 90-97 contrary to other rigs out there. Are the G90 gurus right or are they full of it?
I don't own a G90 so I can't answer this. However, IF you ALC is too low, your PO (Power Out) drops quickly. This means you may have the rig to set up to send out at 18W but actually TX at 8-10W. On the flip side, If you have the ALC too high, you will cause overdrive to happen resulting in distortion. The sweet spot should be just above the zero on the meter bar and just peaking over. I notice I may clip the wave a little but I get maximum PO and still full decode. Again, I don't own the G-90 and wonder why they are saying this. Could be they are saying the same thing but using different way of saying it.
Your thoughts??
ALC on the Xiegu G90, at least with the firmware version I have, is ass-backwards. When there's no ALC being applied, the level is 100. So I take it that when using VarAC, I should be aiming for ALC to be something like 66 on the G90, right?
I don't own one but will ask around. I've talked to users who have successfully use it in digital modes. One issue they told me was getting the right driver. Here is what they use. Choose the CP210x Windows Drivers v6.7.6 9/3/2020. Here is the link: www.silabs.com/developers/usb-to-uart-bridge-vcp-drivers?tab=downloads
I have a buddy in ID who is just getting his up. VERY SMART and will figure it out. I will pass you onto him soon. Stay tune and email me at HamRadioMadeSimple@gmail.com
@@hamradiomadesimple Thanks for that. I've got all of the digital modes I'm interested in working with the G90. Getting the drivers was pretty easy: I am using a Digirig, which is plug-and-play. I was watching your video mainly for tips on improving performance, so if you can find out about the G90 ALC level, that would be great. On another topic, I've been trying without success to get into HF packet. Unfortunately, I've been tuning into 14.105 LSB for the Network 105 stations, as well as 7.104 LSB, and haven't been able to decode many packets out here in Utah. I'm using Soundmodem. I'm wondering whether packet (outside of APRS and Winlink applications) is dying out to such a degree that there aren't any packet operators with a path to me, which would be sad. If packet is of interest to you, I'd love to see you do a video on it.
I don't own a G-90 and it is not a straight forward setup. I will ask those who have done it to document what they did. This won't happen overnight but when I can get it, I will pass it on. Send me an email at HamRadioMadeSimple@gmail.com
I am using a G90. In Vara when it says the ALC should be 1/3, I just assumed that on my 0-100 scale 1/3 must mean 33. So, I followed the instructions in the Vara Soundcard menu to adjust that ALC to around 33, and things are working really well. I typically use around 18 watts for digital with the fan running.
@@tigersire Thanks. Are you using a recent firmware version? I have pretty old firmware because I don't like changing stuff that works! In mine, the ALC is on a 100-0 scale - i.e. no ALC gives a level of 100, full ALC is 0. Seems like yours is more in line with other brands like ICOM, with a 0-100 scale instead. I'm thinking that Xiegu changed its convention somewhere along the line after I bought my G90.
Awesomely helpful. Thanks! KE1TLG
Glad it helped! It was a big change in my outcomes by knowing this stuff. Have fun.
