One of the keys to getting the best out of digital voice over HF using FreeDV is having a good quality microphone fairly close to the speaker. Stephen, VK2BLQ, drew my attention to a "Streaming" microphone branded Anko and for sale in kmart and Target for AU$19.
It has a wire grill with a foam pop filter underneath it. There's a rather weird RGB led lighting effect that can be controlled by pushing the knob. The quality of the audio is surprisingly good! Until I looked closely at it I didn't realise it's also a USB output audio device with a 3.5mm socket under the main body.
USB Microphone:
Location ID: 0x02122000
Connection Type: Removable
Manufacturer: USB Microphone
Serial Number: Not Provided
Link Speed: 12 Mb/s
USB Vendor ID: 0x434c
USB Product ID: 0x4155
USB Product Version: 0x0100
The vendor ID isn't listed in the databases I could find and the main chip has it's numbers blanked out.
Inside it shows a nice large condenser microphone.
If you're looking for a USB microphone for very little money, I can recommend this one. I wish the mount at the bottom had the standard thread but otherwise I have no complaints.
Do you know that feeling where you have a tool, in my case a new 3D printer, and you're kind of looking for things to use it for? I designed a more compact case for the guts of the microphone.
The lip on the lid is 0.5mm smaller than the opening in the box. It's not quite tight enough to grip so I've put two cable-ties around it.
