I see that you have enclosed wiring in a tubing, did you twist the wires before sliding into the tubing. It seems that if you don't twist the wires or replace with shielded wiring there is a lot of

Nice job on the layout Ron. Like Mike said, try some 0.1uF caps on the 5V raduino regulator. I didn't see the 4.7K pull up resistor on pins 2&3 of the raduino either. Try another spkr direct to board

You should check out tindie.com they are set up for small sellers and more geared towards electronics than Etsy. Ralph N9WTX

Hi Everyone. I am happy with my RaduinoI2C board and the Audio Board. I havent build a HPF or LPF yet(other than prototype) but they are straight forward, still waiting on the CW filter... Now Im

Nice build Ron! I suspect you have noise from the display getting into your audio.? This may be an earth loop issue, or it may be leaking directly in to your speaker as it is shown in the photo

Not necessarily grandpa's. ?I just now noticed the signature in the image, here's more of them: ? ??https://www.pinterest.com/pin/416090453046673659/ A very famous film star from the 1920's. My

Thanks for the suggestion Nick, BTW... I’ll buy one of those boards if you sell em.? I’d considered tacking a relay onto a Hi-Per-Mite but yours would be more elegant.? Let me know.? Pete

The white panel looks like nylon.? I use sheets of that to make guards and guide for table saws, routers, etc.? Very slick stuff.? Pretty soft to machine, drill, or cut.? But makes a super slick

FB Vince. That's a great looking rig with the Pi interface. I might swap cases and do something similar? with my new uBITX instead. Could you drop me an email at mycall @ RAC.CA? I would be

All Good today.? Once the KD8CEC software was installed, finally found a newer Memory Manager. Maybe a Link in Files here for all pertinent programs, ie. uBITX Memory Manager all recent versions that

where to order this case looks great

Hi, Chop up a set of cheap in-ear headphones.... See my new board, awating delivery:?/g/BITX20/topic/14920831?p=Created,,,20,1,0,0 Ill post up pic of it installed once done. 73

A thought occurred to me, it seems like a few other people have had this thought too, but Teensy would make a good drop in replacement for the nano. I’m trying to get the 0.20 code ported over to

Gerald Thank you for your feedback. I also confirmed the issue you mentioned. This is the part I did not test and it is my mistake. This has been a great help to me. I will reflect on the firmware

Worked David N8DAH up on 7,287 with weak signals both ways and Don - VE3IDS in Ontario. He was on an HW-100 and very strong here. -- John - WA2FZW

Opinions of help needed badly here.? About the 5th or 6th time I have turn it on, I was listening to Tom E3TH (I know the call is wrong.? All I could get) the entire 40 meter band has these

Solved it. For Board, selected Arduino Duemilanove in lieu of Arduiano Nano. Links: ------ [1] /g/BITX20/message/44881 [2] /mt/15545056/535143 [3]

Looking for source of small gauge, shielded but flexible audio cable for internal wiring.? Also looking for how folks might have added an audio filter like the Hi-Per-Mite filter internally to the
