Thanks for the info. ?I don't have any surface mount stuff, and really don't want to get into miniature stuff, but should be able to find a suitable ceramic cap around here somewhere. Greg KD7QX

Thanks for the reply. I may have a defective board as it uploaded ok BUT no frequency read out... Mabee it is the oscillator portion that isnt working... BOB K6YN Sent from

Hi Greg! C107 is RF grounding the balanced modulator, so you need it. It is a 100nF/25V or 50V X7R capacitor. If you do not have an SMT part you can solder a regular ceramic cap on the pads. Probably

No worries, Bob. It's just that the string manipulations aren't standard Arduino. I fixed mine but you need not be concerned as it will work just fine. -ND6T

THANKS to ALL that have helped! I finally got my computer to UPLOAD to my Arduino Nano! However I still have compilation errors. See attached pdf Any suggestions?? BOB K6YN Sent from

I'm KD7QX, and new to the group. ?I received my bitx40 earlier this week and Thursday finally found time to go through everything carefully. ?I've read the wire-up materials, the circuit

No. But in my case it was handy to have another input pin available after the pots center signal input on A7 of the Nano went kaput. It was shorting and drawing current, heating the voltage regulator,

Thanks Todd, The pen mic works great on a lot of my different radios, I should probably build a backup:-) Joel KB6QVI

I bought the case from this EBay supplier, https://www.ebay.com/itm/252330916481 and the mic I built from a old ink pen, it works good and I get good audio reports with it. Joel KB6QVI

Really a great job, Joel! Your pen-microphone is very cool. 73, Todd K7TFC

Not sure how it will sound, but I ordered this one from EBay: 1pc SPEAKER YD87 8OHM 87mm 8W SQUARE / MYLAR CONE LOUDSPEAKER TRANSPARENT | eBay. It's a little under 3-1/2 inches diameter. I wanted

Where did you get the case from? What mic are you using? *Kind Regards,*

How many watts is optimal for the best sound?

Hi all, My BitX40 is finally finished and mounted in a a box with the Raduino installed and functioning great. I decided I didn't want all the heat from the 5V regulator so close to the clock crystal

Anyone here actually used a 10-turn pot with the Raduino instead of the one supplied? If so, how well did it work in comparison? RichKC8MWG

I noticed all the extra wires, question, what are they for ? Do they do anything ? Phil G7BZD
