Got it working, tapped in just after c106 and used the ground for the missing variable cap. I'm still working on getting it tuned up. Its off frequency and not sure why. I'm using this formula to tune, clk0 is the bfo.

void setFrequency(unsigned long f){

? if (isUSB){

? ? si5351.set_freq((usb_bfo_freq - f) * 100ULL, SI5351_CLK2);

? ? si5351.set_freq((usb_bfo_freq) * 100ULL, SI5351_CLK0);

? }

? else{

? ? si5351.set_freq((bfo_freq - f) * 100ULL, SI5351_CLK2);

? ? si5351.set_freq((bfo_freq) * 100ULL, SI5351_CLK0);

? }

? frequency = f;

}

Added a pic where I attached a mini coax to go to the raduino

just to communicate with the arduino

Thanks Jack, I have downloaded the etherkit si5351 v1.1.2 as per Ashaar's post on the subject as I believe the v2.0 does not work with the raduino sketch.

I will check the directories are named correctly and see how I go tonight when I get home.

Are the I/O drivers just to communicate with the arduino or are they something to do with the si5351 chip?

So I have the BitX40 all running (not in a case yet). ?I also have the arduino firmware downloaded and want to make a minor change in the way the frequency is displayed. ?Instead of it being displayed as 7.XXXX I would like it to display 7XXX.X. ?Can someone help me on what changes need to be made in the programming in order to accommodate this. ?I know this is pretty superficial, but I think it would make more sense in seeing the display this way.

Thanks in advance

Raj,

Thanks for that. I have already started on the analogue vfo. I have lots of 1960's components! Should be less of a compromise.

The Raduino might be used later at 19MHz to produce usb for data/wspr. Could one make a dual 40/30 meter usb transceiver by adding 22MHz to the Raduino? Would a 10MHz bandpass filter reject the 12 MHz IF sufficiently?

73 Brian.

Very strange. ?Could still be a bad crystal ?Good enough for the G3UUR oscillator, but not good enough for the Si5351. ?Sometimes crystals get sold cheap if they don't meet factory spec, but as you say this is getting doubtful. ?Or could be a bad Si5351. ?I'll be back to my bench in a few days, will try shorting out the crystal on mine and see what the output is doing.

Finally in the BITX40 "club"--ordered mine on 2/22; arrived today (3/15). Serial number appears to be "O3-321". Need to decide whether to build a case or buy one. Leaning toward building at the moment...

Hi Jerry,

we might be on the wrong track here ... last night I quickly put together one of these G3UUR crystal test circuits. Put the 25 Meg xtal from Raduino, and I'm getting 25 MHz out (actually, 24.99459 MHz). Didn't have another 25 meg xtal to put in the Raduino, but tried 20 MHz that I had on hand, tried probing but don't see anything. Still getting same wrong frequencies at the output as without any crystal. Granted, I know that 5351 needs either 25 or 27 MHz crystal, and I'm not sure if 5351 would even consider working with some other values. Worth a try.

But, it's definitely not a Nano, because I have same results with Arduino Nano, Arduino Pro, Arduino Uno, and Freeduino, all from different sources. Well, chasing this problem was so fun that I sidetracked from BITX itself. Now, I'll just use Adafruit's 5351 and get back to BITX. I have no intentions to try to desolder Si5351 from the Raduino board ;)

Description:
A document that shows how to install and test the Arduino IDE. Loading the Raduino sketch program entails the same process as the Blink sketch program discussed here.

Thanks to all who have offered resources for learning arduino, it is all helpful. My question was more specifically what I need to do to upload a new sketch to the raduino. The reason I asked this is that there are a number of posts where people have attempted to do just that and they get multiple error messages. If there was a step by step guide then many of these errors may be avoided.?

So is there anyone that has successfully uploaded a new sketch to their raduino and if so what are the important bits to make sure you have setup prior to uploading the sketch.

By the way, I no Arduino is Free.? I have had so much fun with the IDE and cheap boards, I chipped in $10 a few times.

Each time you download a new version, they give you a chance to donate.

There code takes away a lot of the more difficult items of learning C++.? You get to actually make something work, rather than

fighting with code syntax.?? Some of us don't want to fight learning how a compiler works, or if a variable is a constant or public?

And, if you want you can continue to become a C++ programmer if you want!? I think they have come up with a real useful solution.

I just can't believe how neat and affordable this stuff is!

I get the following message when trying to upload: ?Any suggestions would be appreciated. ?Being a noobie, this is all Greek to me.
