Thanks Jack, I'll give that a try and will let everyone know how it worked. I should be able to give it a try tomorrow, 73 de KB1VNA Eric

I am getting this same error when attempting to compile

Which version did you use before (when you didn't have the clicks/birdie)? What happens when you restore that previous version? 73, Allard PE1NWL

Jonathan, You don't need to remove the xtal. Much easier is to just remove R101 to disable the analog BFO alltogether. Or lift one leg ("thumbstone" it). If you ever want to go back to the original

The loaded sketch is what has been referred to in the group as the latest 'standard' raduino .ino sketch. And yes I had the Si5351 library 2.0.1 loaded in the IDE, that's what I don't understand. As

Yes, the WebSDR online receivers are an excellent way of monitoring your transmit audio (I should have remembered that option) but be sure to use headphones and take precautions to keep the receive

I was told some similar things in the beginning about my monitoring my muffled audio. On my SW receiver it sounded like I was talking into a fan. Look on the internet for something Called WebSDR.

Is this new standard, a raduino.ino sketch version?? Probably what happened is when you uploaded a sketch, your IDE software uploaded an updated Etherkit Si5351 library ?with the sketch. That's

That was meant to be printFrequency(c, frequency); Sorry

Hi Andrew I did just try your suggestion and had this message. 'printFrequency' was not declared in this scope Thank you for the info thou.

I am having sort of the opposite problem. I had the original Raduino sketch loaded with no tuning clicks and no birdie at 7.199. Then I loaded? the new standard?? version 1.05 and now I have a very

Take a look at this mod by Don Cantrell. I've done this on my BitX40, it was easy to do and works really

Good! I had borrowed that code from Farhan's original script, which compiles with the older etherkit library. All three of the lines of code I gave you should either reference CLK0 or CLK2, I gave

Got CLK2 going! I did have to change: si5351.set_freq(11998500L*100ULL , SI5351_PLL_FIXED, SI5351_CLK2); to si5351.set_freq(11998500L*100ULL , SI5351_CLK2); due to compiler complaints. Thanks for

I am hoping my muffled audio is just some kind of input circuit mismatch with the new RS electret microphone element vs the original electret device. The more technical answers aren't ones that I

Might be worthwhile to add a small series resistance and some sort of voltage limiter (Zener or active limiting circuit) to insure that the ADC input does not exceed 5V. Returns from the ADC will be

Thank you Jack but that went right over my head. I did try to add pinMode(A2, INPUT); To where I thought was the setup but had a load of errors straight away. Like I said I'm not one for this

The numbered pins correspond to the numbered plug parts. And the plugs numbered wire connection points correspond to the plugs numbered shaft points. Pin #1 is ground or (-) negative Plug parts #1

That's what happens when you come back for a few edits, but don't do a final proof before hitting send. Should read: ?"The flash of light was likely one of the traces blowing between PA 12v and the

I am more than satisfied with the performance of my Bitx40. It exceeded my expectations and the support from the group emails has driven me further to explore. If I wanted a 40M qrp rig I would have
