One item to note... All the stitching, those are the vias fro top ground to bottom ground. I have a bin full of those relays and they are compact, inexpensive, and good at RF. Allison

Lawrence, I've replied to the email you sent earlier.?? Many thanks, Carl

John: I added a print statement before and after the first i2c write and it is definitely the I2C that is hanging up, it doesn't get through the write statements. Great call! Now I have to figure out

Carl - Check your Email.. I need your paypal info...

John: I did find a short between D3-D4-D5 under the connector to the uBitx main board. I don't know how that happened, since I didn't touch that connector doing the rework. Anyway, the problem didn't

This is great news Allison, I offer to layout the boards and make the files obtanium ... Rahul VU3WJM

Ashhar, Just out of curiosity, do you have any new projects you are working on? Al, N8WQ

ARV, feet of AWG-20 is so insignificant as to have any large effect on performance.? I?<< There are several effects one is the DC resistance of the wire which is small. Then the AC resistance due to

Hello Howard, Based on what you describe I suspect an issue with the I2C bus. Suggested tests would be either to a) Comment out the wire.xxxx call lines in the si5351 tab or b) Load my test program

Here's to a free and independent India.? Happy birthday. And thank you, Ashhar Farhan, for making this versatile platform available. Salute! Russ Hines JMS & Associates, Inc. SBE CSRE WB8ZCC -- Reply

Hi Nick, We think alike you and I, this is exactly what I have been doing for some time now. Progress is slow due to work and family commitments unfortunately. Will be happy to share thoughts and

This might be useful for both Tom and Howard: Every now and then, the serial port on my Mac gets into a funky state, and I can no longer upload to the Nano, and I have to reboot the computer to get it

Those are great ideas, but what about a limitation on cost? Should be under $140.

Nick, I already started to do "my" improvement on the ?BITX, but then stopped, after reading and trying to understand all the issues involved and going back to ideas about a spec and blocks to be

This is a LP filter from a Codan radio. The RF has a straight path to the antenna port. SWR bridge is to the right. They are very clean. Regards Adrian

Ihaven't tried this, put something like: void setup(){?? int i; ?? for (i = 2; i < 14; i++) {????? pinMode(i, OUTPUT);????? digitalWrite(i, HIGH);????? delay(10000UL);?????

Is it just that the program hangs, or are you no longer able to upload programs to the Nano? I've started to have problems uploading programs to clone Nanos with my Mac, after I upgraded to the new

It might cost another $0.20 to have a red LED on the front panel that lights up when audio peaks from the mike amp exceed some level at which the mixers start to misbehave. Not much point in doing so

Also, the hello world sketch works properly. This proves the display and the Arduino are alive. I am guessing the code is looking for a specific state on an I/O pin to move forward and is not finding

Jack: Thanks. I am running my customized version which I have been using for a few months. I also tried the original code, but I get the same exact problem. It would be nice to have a flow chart for
