Alan mm0wxt Gate voltage only determines where on the voltage versus current curve the device is operating. As you mentioned, different MOSFETs will show more or less gain at a particular gate

I have been asked if I had a uBit Raduino by many who bought RaduinoX PCBs. I have sold over 50 X PCBs and tested units. Well I finally got a few built and tested today. The Big Extra is I added an

Hi, thank you for the new s/w. I'm mainly doing CW and very glad that I can use my Bencher paddle now without any wiring modifications. There is still one issue to discuss: the WP (wpm?) display which

Newbie question here. I read that the IRF510 gets unstable and breakdown at 3-4 volts. When setting RV2&3 to 100ma each , when i check the gate voltage it is 3.60 and 3.99-4V(2 different irf510

Wire that female jack tip + and sleeve - Using a stereo to mono adapter (if you want sound in both ears) both right and left channel + would be connected to tip + and the common shield/ground - to

Certainly! But only with binaural inputs. Especially with my binaural receiver! With a monoaural input, no, I've not noticed any weird effects. I'm just listening to 500 Hz wide CW bandpass. Often

Has anyone tried one of those adhesive heatsinks made for the Raspberry Pi ic's? Is this a long-term heat problem the heatsink might help. It certainly won't if it is from charging current into the

Re-wrote it entirely. Single file, straight Arduino. The principle reason was to use my agile tuning method. That, and I enjoy making modifications and I can't follow the other software. -Don

It appears to start over with each batch; the first batch was around 1000 pieces.? Watch out for the U1 TDA2822.? If it has WX on it please consider replacing it with one from a reputable

Thanks Don, Are you using stock code on uBit, or did you re-write it??? I would like to use CEC code. It seems to work better than stock uBit? Mike, WA6ISP

Thanks Jack. I’ll take your advice and see what happens.? Appreciate your help.? Guy N7BIR

Hi Mike, Last year I bought 10 of these from Amazon for $5.32 delivered. Sodial. They have proven to work perfectly. I use them for signal generators as well as for one of my BITX40 builds. The trick

According to the theories on how serial numbers are assigned, my uBitx received yesterday is from the 3rd batch.? The serial number is n 376/3.? Does anyone know what if any differences there are

Thanks Arv, I have always used interrupts, and use it on BitX40.? I can't use some of the features of Allards software, because I only re-wrote the code changing frequency. I like the interrupt

Randy, That would be my suggestion. Wiring the tip to the positive output from the 2822 and the ring to ground will certainly work but I question the audio artifacts that can be seen when driving

Mike WA6ISP Rotary encoders can be a pain to work with, but in reality are quite simple. If we assign the two outputs as out-A and out-B then rotation in either direction will show phase offset

You might want to take a look at the Case I designed for the uBITX.

A LONG time ago, I used a 1.5V battery on speakers to mark their terminals for phasing with stereos. You feel the cone Jump in or out to figure out the terminal polarity.? I would just mark them
