Hi Scott

Your tutorial discusses ===>
"2.0 This document is divided into the following parts.



A review of the functional basics, rules and software limitations associated with the PowerSDR virtual audio interface.
Suggestions for testing and tuning system performance for real-time audio.
How to quickly setup a USB headset for use with PowerSDR.
Virtual PTT switching for virtual audio.
Latency: what it is and how to minimize it.
How to setup up Voicemeeter Banana and interface digital mode software audio streams.
Virtualizing CW operations.
Integrating Digital Audio Workstation (DAW) software.
"
but I do not see anything about how one can plug a microphone into the computer running PowerSDR and
pipe the audio to a remote ANAN-200D/7000dle/etc using VAC1.

Is this possible ? My radio room in the shop gets down in the low 30's quite often in Winter and operating there gets
pretty uncomfortable!

Dick,

Yes, using VMB to route microphone and receiver audio was not covered in the tutorial, which is pretty basic. My radios live in a rack in the basement and I operate exclusively from my second floor studio office, i.e. I do exactly what you are seeking to. I will address your questions in your other thread--look there soon.

73,

Scott

Many thanks for addressing this topic. It seems like every time I try something related to software applications changes
it ends up being a "tar-baby" where the problem just gets worse! Then I spend days getting something that worked
fine back in operation.

RF and circuit design is a comfortable arena for me but this computer stuff seems like fighting in a Vietnam jungle

I will look at what your next posting provides. Again many thanks for your SW-knowledge and dedication to growing
the SDR spirit in our Ham community.

I thought this facebook post by voicemeeter might be a useful reference.

"Let's remind the Voicemeeter internal audio routing diagram to explain how this is logical! Like for any hardware mixers you can get this map in mind: Audio comes from the top, then goes to the right by the BUS assignation buttons and finally goes down to audio outputs"

Tony -- Tony EI7BMB -- Many thanks for the detailed picture of Voicemeeter's signal routing.

VM and my computer have been playing well for me for quite a while now BUT sometimes I
have to resort to my detailed notes for all the settings in the WSPR/VM/Soundcard
configuration when everything quits working together.

73 and THANKS to everyone who turn on the 'light' in dark situations.

Glad I could help Dick

I've just installed voicemeeter potato 64 bit version and it seems to be working well so far.

Scott,
did the tutorial get moved? This link is not working for me.

My apologies, my website is down, the server had a major hardware failure, spare parts will not arrive until Monday.

My Thetis audio was fine since I was running voicemeeter as you suggested.

Recently it stopped working and I have no idea any more what went wrong. No more audio via ASIO... Did not change a thing. No more audio to or from Voicemeeter from Thetis. Can hear my own audio in voicemeeter.

classic VAC works OK.

Any tips? W10 updates related maybe ???

@ON7WP

Start a new topic in the Digital (Virtual) Audio sub-forum, please, and we'll sort it out there rather than clog up the tutorial topic.

Scott,

I spent the afternoon working my way through setting up VAC audio through the PC using Voicemeeter/Banana.
'Love the quality of the sound through my high-end studio monitors.
Now, I am ready to set up microphone transmit using VAC. I have read your summaries and and those of W1AEX.
My goal is to use the EV RE-27 N/S microphone currently plugged into the front of my 7000DLE MK III. Nothing I have read tells me how to use a good dynamic microphone and transmit through a VAC. I am guessing that one way to do this is to run the RE-27 to the XLR jack on the back of an external sound card and from there to the line-in jack. Is there a way to instead utilize the PC's sound card? Is there a tutorial on this subject available? Thank you!

You are correct, you need an appropriate sound interface. Most folks use a pro style USB type. There's no tutorial per se, but this topic might get you going down the right road:
