Bill & Mike--- the mic looks much like a pencil -eraser end with 2 solder blobs on one end, black felt on the other.. That's the end you talk into.. The encoder is less than a postage stamp square,

I just received a uBITX yesterday and I'm a total noob at this. I have a small cylinder about 1 cm in diameter and 1 cm high. Is that the electret mic? If not what is it? I do have a small rectangular

Re: Exciting times in the uBITx world
I ordered a 3.2 enhanced from ITEAD on their website. Then I looked around AliExpress and Ebay just to see the knock-offs. Funny, no particularly compelling savings (most actually more expensive) and

Re: uBitx has a bit too crispy / semi-distorted audio even on low signal levels #ubitx #ubitx-help
Good Mike, To make it ultra neat: solder back the diode and cut the track inbetween the diodes. Solder a fixed resistor between the cut track (you need to scrape it but a resistor may fit between the

Did the biasing mod. That solved the crossover distortion issue. I took a 500 ohm pot and paralleled that with a 125ohm resistor. The mod doesn't look so good? (LOL) but it works. One of the

Mike, Try this: Lift up D15 or 16 diconnecting one end from the board. Solder the center and one end of a 47 ot 100 Ohm preset between the two diodes. Make sure the preset is at minimum. Power up and
