If keeping the various cables away from power supplies does not solve the problem (though I agree that it should), another place to look is the impedence from the monitor out and the mic in. An impedence mismatch could cause some hum.
I get the noise mentioned, I use a Yeasu FT-450d with an SM58 mic and footswitch. I have to turn the mic gain in the radio down very low else there is some noise/distortion. If I go thru a mixer first it is even worse! The mixer feeds Line level and the radio is looking for the lower Mic Level signal. So if you are getting a noise/distortion need to find a way to lower that Line level out of the mixer to Mic Level at the front of the radio. Some people use D I boxes like you would for an acoustic guitar into a mixer. This you can remove gnd noise as they tend to have GND isolators and some have attenuation pads which will lower line level to mic level. Good luck I just go straight in with gain practically off and live with slight noise (seen and heard on a dead key) Use a web SDR local to you for testing
My suggestion is like Mike said, USE FERRITE on everything. The hum is likely from a ground loop in the audio chain. This is not uncommon. If this is going to the radio, the real help will be from using an audio isolation transformer (with a ground lift ) coming out of the mixer. This should also have an option to pad down the audio going to the radio. Just a thought,
I do HF mobile livestreams, I use OBD for the software, using a capture card to capture my radio screen, I have my razor pro web cam, and when it comes to the audio I use a 2 wireless mic set up on one channel with my transmit and receive audio coming directly from my heil pro7 headset. Keeps it real simple but it took a good bit of researching and experimenting before I got to this stage. No need for those expensive wireless sets either I found a set made by kimafun for a fraction and the quality is awesome. I am always amazed at how much tech is evolving, like those big sound decks you have, comparing to the likes of the rode streamer pro. Maybe work you on HF one day 73 from Scotland
Question: Why oh why, do radio makers ,who have radios with removable faces, do not run the mic to the face, instead of back to the radio? This never made sense to me. I've had a couple of Yaesu like this. Thanks, Rob W8REJ
What are your EQ and Gain settings for your mic on the mixer and the EQ and Gain settings on the radio? Also do you have any mic processing turned on on the radio side?
I took the 50/50 gamble and watched it. All good, I am now smarter Mike.👍 A comparison on coax brands would be great. I prefer spending once if I can afford it... even if I have to wait like waiting to get a HF radio.📻
i am very surprised that you dont use the sub group 3/4 outputs for the radio and the mains for the pc that way you can have stereo into the computer, as for hum, you can actually cut the ground on the usb cord to the mixer and that will avoid that ground loop. What is the part number for the heil adapter to the radio? I have the headset one, which will work, but i need to find the pinout of the 3.5mm TRS jack on the adapter
Mike great video like always. The audio is great but you running it a little bit hot. And if you check the part of the video at 5:08 you can see it was clipping. This is no disrespect to you just a friendly observation. I am still working on getting my audio perfect I have been using a OBS for a few years Now but never with a radio until recently. Hope to perfect it soon. Thank You mike for all your content love them all. Also your the funniest ham operator on UA-cam for sure. 73 from AC1O
I know. I actually cleaned the mixer before shooting and moved some of the knobs. I'm keenly aware the mic was too hot. Glad you think I'm funny though. Like I'm a clown here to amuse you lol?
Simply brilliant, I was trying to understand this connectivity between a mixer, audio interface and yes the incredible OBS software showing multi cams... I wanted to know if this same procedure of sound mixing can be done for the Yaesu FT891? And also a smaller mixer-cum-USB audio interface if you can please suggest. My qth is in New Delhi, 🇮🇳 Cheers!
ABR INDUSTRIES ???? You got to do a video on them! Never heard of em, and we NEED more options in today's market! I bought 100ft LMR400 from a EBAY seller- ( 7eighteenelectronics )of USA , a NY based company, for my Base Station, so far it lasted 2 winters here in Maine Every 6 weeks or so, I put my antenna anylizer on it and read the meter, Its doing real good. One of these days i want to see what that Heliax stuff is all about. Great video! Always nice to watch your vids, and the links u provide help me out. MidCoast Maine waiving !73 ! stay warm, stay safe !

You bet!
I use to have that same mixer and replaced it with a Behringer XAir 18!
Isn't is amazing how little shielding really is in XLR cables.

Mike, he may also be experiencing ground loops. He may have to put isolation transformers on his audio lines. Enjoy your videos. NM5BB Bill Boedeker
You are now my second OBS expert I'll contact for help! LOL! I liked the info about the mixer. One day I'll grab one when I'm ready. 73!
Ha! I don't know how much help I can be cuz I really don't know what I'm doing but I'd be happy to try.

Dvi to HDMI cable. Because the amateur radio companies haven't updated to hdmi
Yes, that's it. Maybe one day the radio companies will join the 21st century. prob in the 22nd century.

No reason to send a stereo signal. It's not like I'm panning left or right. This is the adapter I'm using. www.dxengineering.com/parts/hls-cc-1-xlr-i
What’s the audio chain the other way? From the radio to headphones and speakers? Usually once the h/p Jack is inserted, it mutes the speaker.
There is no other audio chain. For live streams I plug in the headphone jack to route the audio the way I showed. When I'm not streaming I unplug it.
Mike great video like always. The audio is great but you running it a little bit hot. And if you check the part of the video at 5:08 you can see it was clipping.

Thanks for the great video. I’m doing the same except I have trouble setting the level (gain) on my ICOM 7610. How is yours set?
My mic gain? I have it set to 25%
Have you tried out that audio chain on AM yet? I bet you would sound amazing.
Sure haven't. I think I've only done AM once.
@@hamradiotube You should think about trying it.

Cheers!
Yeah it should be the same with the 891.
Very interested in this one.
Hope you enjoy it!
I'm not sure if I'll watch as Mike has a 50/50 chance of turning into a real Gremin.🍻
Only if you feed me after midnight.
@@hamradiotube haha, very true, I forgot about that.🚫🍲🍻😆
Mike, was that an example of cat control?
it was
Superb! Seeing your setup is instructional. I for one really appreciate it. Will you be at Hamcation?
I sure will. You going to make the trip?
@@hamradiotube That's the plan!
Nice.....

Well I already did one...ua-cam.com/video/IMs29HnnfjE/v-deo.html
@@hamradiotube thanx!! sorry, i am a new subscriber..i am sorry about that.
@@Maine307 no worries. Happy to help.
Fascinating!
Mr./Ambassador 🖖.(Spock)
Thanks!
A wild SATAN appears!
You never know when he'll appear, just know that he will.
I think you meant "Display Port" Mike
Probably.
Masterfader, wait, what?
It's not what you think.
More than likely is he has a ground loop... line isolators are probably going to be the cure. Toroids will only stop minor problems. Sam N9zfn
