Hi Don - I tried a small RG174 cable and unfortunately it didn't solve the RFI problem.? Still getting a very strong garbled RFI when I transmit SSB and the audio cable is connected.? Grounded at

Yes, you are both quite correct. Ground both ends of this connection. -Don

Got it working! Seems like a bad connection on the mini USB connector.

Okay, now it compiles, but it doesn't recognize the Arduino. I installed the CH340 driver, but it didn't help. Anything else I am missing? Howard

Peter: That did it, thanks. I should have remembered that myself, not the first time I experienced it. Howard

Jack: Many thanks! I have a few days off work this week and plan to spend some time on your Beginning C for Arduino 2nd ed. Regards, Craig w9ctw

Skip: Thanks for the offer. I just ordered them from Mouser, but I probably won't change them. Just send me another SASE I will send you more parts. Howard

Thanks for answering Craig Jack - I've been wondering about that for a few days :)? You learn something new every day. Martin - G4FKK

I have one of these keypads (which includes a resistor matrix? built in for connecting to an analogue pin) https://robotdyn.com/button-keypad-4x4-module.html I have yet to deploy it ... a future

The?16 key?TTP229?capacitive touch keypad might be worth considering as an easy low cost external keyboard solution for the uBitx, it worked well for me on another Arduino project See

IMHO, small interconnections, you need both sides ground. Earlier in telecom we used balance twin wire cable with shield. There we used to ground at one end and if some one grounds at both ends, the

how did you power it - by smps wall wart mor linear or just a battery? regards sarma vu3zmv Regards MVS Sarma

Hi! I built Bitx40 about 2 weeks ago. ? I measured the spurious of Bitx40 by using the spectrum analyzer. The level of spurious of harmonics were under 50db. So this is fine. But the spurious at

For what its worth, I had a similar error (function does not return a value) on the macbook. The same code compiled on the win10 system. Updating the arduino ide for the mac to the latest version

Howard do you need some 510’s , I’ll trade a few for some more of those caps and inductors for the driver mod. I got another board that needs them. Skip Davis, NC9O

Yes, the UBitx is a nice piece of engineering. Hats off to the developers. For myself, I don't listen to AM broadcasts for their music content rather I listen to the BBC and other foreign stations to

Linux doesn't show hidden files by default. But you can see them by typing: ls -al in a terminal window when you're in the directory you want to examine. To hide a file, rename it with a dot ('.') as

Another thing to watch out for, at least it's something that has caused me some grief at times when loading the tft files on various displays... You may get a message on the display that the load

Michael Thanks for your suggestion. i will implement them before the beta version is over. Ian KD8CEC 2018-06-25 11:04 GMT+09:00 Michael Babineau <mbabineau.ve3wmb@...>:

Jack: That helps, but now I get other errors. There are also lots of warnings. invalid conversion from 'const byte* {aka const unsigned char*}' to 'uint8_t* {aka unsigned char*}' [-fpermissive] Howard
