The instructions for the volume pot on hfsigs/wireup are neither correct nor incorrect. ?They speak of left and right terminals without specifying whether you are looking at the pot from the front or

Swap the red and black wires on your Volume pot, the instructions are incorrect.

My LED (D4) is on solid when working. LED (D3) Blinks when turning tuning dial. Sent: Monday, March 13, 2017 2:41 PM To: [email protected] Subject: Re: [BITX20] Bitx40 another Raduino(?)

I can't be of more help as I just got back from vacation and my B40 is still in pieces on the bench. Also, I had 6" of water in my office because of a power failure/sump pump failure. I guess "Desktop

I'm not receiving anything with my newly constructed bitx40. It sounds like this: I tried tuning around the band to find anything and this is the best I got: Any thoughts? One thing that's

Try listening with a shortwave receiver. ?If the 25 MHz crystal is oscillating you should be able to hear it with a general coverage receiver in SSB or CW mode. Use a short piece of wire as a probe

Check and see if you have any baseball cards in the spokes? ?:-)

Giuseppe Also twist the fan leads together. Randy, K7AGE

I would try a ferrite choke and .1uf capacitor on the leads to the fan. Just a thought. Good luck. Marco - KG5PRT [email protected]> wrote:

Hi Jerry and Kent, Yes, I was just reading this thread and thinking "boy, I had exact same frequency at the output, 4.74 times lower than it should be". Unfortunately, I didn't fix it - I ordered

At work when a PC board drops to a concrete floor, often the only part damaged is a quartz crystal or crystal oscillator. ?Goran reported previously that his Si5351 was emitting 1mhz instead of 5mhz

I suggest that you get in touch with 9H1SV Regards Lawrence

I got solid light from the red LED on Raduino, no blinking

Goran, VE6GPO, reported that same problem. ?I don't know if or how he resolved this: /g/BITX20/message/21886 ( /g/BITX20/message/21886

Thanks, Randy. It is a bad output from the Si5351 with only about 1.052.8MhZ coming out at pin 14 on Raduino#895. The other Raduino has 4.986MhZ. Thanks for the documentation to help me chase

Is the LED on the Raduino board flashing wish a one second period?? Jck, W8TEE To: [email protected] Sent: Monday, March 13, 2017 1:43 PM Subject: [BITX20] Bitx40 another Raduino(?) problem

Thanks! works well. I added some code that increases the tuning step after sitting at the extreme end for a while so you can tune faster. Also set the delay in step to .6 seconds as .2 was too fast

Thanks Randy, Good to hear that raduino v1.0.3 is working well! Yes, you need to install the newer si5351 library v2 to compile it. This is also mentioned in the README document. The old v1 library

Jerry, thank you very much! I just finished putting together a RF probe for troubleshooting this problem and that post should be very helpful! Thanks, Roy WA0YMH [email protected]> wrote:
