SUCCESS !!! Turns out the radio needed a change in its menu to select the audio input. Made my first QSO with the Micro this morning. Good signal reports, except two stations said it needed more treble. I was using the internal mic in the notebook. I assume a decent mic will improve that.

Thank you for your help, Roland. When I select the internal mic on the computer, as soon as I push the PTT, the TX meter on the RRC-Micro panel shows half-scale, even though I am not speaking. When I do speak it barely moves. I tried it on a UHF repeater frequency so I could listen to myself, and still not audio making it to the radio. I will check the mic cable and straps on the RRC-Radio box. (Radio is an Icom 9100) I have Mic gain set at 50% on the radio.

This is in the setup instructions on the website:

Audio Mic
 
Select the microphone to use.  Any installed microphone can be selected. However, for full operation you must select 1
274A Microphone as this is the only one that can handle PTT.


That is what I didn't understand. But if the PTT button will STILL work even if selecting a different microphone, tha options for picking a mic are expanded.

No, it is MY misunderstanding. Now I see how it works. Now I just need to see why noone seems to hear me.  :-[

Dear Roland:

That is what I thought.....but just like in the first screen shot you posted, the system microphone is MUTED (there is the red slash thru it). How does audio get to the radio if the microphone I have selected shows Muted?

I thought you could select any audio source once you had the dongle plugged in.  Once I plug the dongle in, windows (7/64) mutes the internal mic in my notebook, and even if I unmute it, once I push the PTT (which does key the TX), the internal mic is muted again. Do you HAVE to use a mic plugged into the dongle?

Thanks so much for trying. Ill try using short cables.

Well, looks like it is the LEVELS. I got into windows settings, and turn the Microbit Mic ALL THE WAY UP. Still barely is heard by DM780. Can't see any way to increase the levels.

That's what I was hoping, but can't seem to get it setup.

In the Microbit RRC Client, which mic/speaker settings are you using?

THEN.....

In DM780, what "soundcard" selections are you using?

I *thought* I understood windows until now.....ha ha.

Using a cable from the notebook's speaker out to the Dongle's mic jack, and a cable from the notebook's mic jack to the dongle's speaker out, it works fine. I was just understanding Mitch as saying that you could feed the audio to/from DM780 in SOFTWARE, WITHOUT cables by selecting the Microbit 1274A in the DM780 menu.

I think it would require an additional item in the driver, to select the Microbit speaker as a RECORDING device, maybe naming it Microbit 1274A PSK RX, and to select the Microbit Microphone as a PLAYBACK device, maybe naming it Microbit 1274A PSK TX.

I don't know how you have it working. For now, I guess I'll make up some short cables.

I am using 1.6.6 . In device manager, it shows one entry for Microbit 1274A.

But these are the screenshots from DM780. It separates them into Microphone, Line, and Speaker. You can see the options it offers.

I cannot select the microphone for OUTPUT, only INPUT, and I cannot select the speaker for INPUT, only OUTPUT.
I need them the other way around to get the audio from RRC-Micro to the program.

I also use Windows 7/64

Mitch:

The soundcard selections for DM780 are made IN DM780. It is there that I am limited in which one to chose.

Hi Mitch:

In DM780, it lists Microbit 1274A Microphone, Line, and Speaker separately. That is where I see the problem. On Input (to DM780) they do not offer the 1274A SPEAKER, only Mic or Line. And vice-versa on Output (it only offers 1274A SPEAKER, not mic).
