Good morning all,

I'm having a problem with an Si5351/Arduino nano kit that I'm hoping to add to my pre-Raduino BITX40. I'm using the code site.?

The trouble is that the LCD only refreshes with the current frequency when the button is pressed to change the frequency step. Once I do that everything updates, but you can turn the encoder all day long and nothing will change on the LCD until you push the button to change the step. I've looked over the sketch and am just not seeing the problem. Can anyone else see where I'm going wrong? I'm using AK2B's sketch as-is with only the pins changed to match my setup. (Let me know if I should post the sketch. I wasn't sure what the etiquette was in this case.)

Any advice would be greatly appreciated!

So you could barely hear that third one, and he was 7.6 miles away? ?And not the other two? ?But your receiver is otherwise working OK? ?If they are running at the same power level as you, thats a pretty good indication of what your rig would sound like at their end.

For a guy who used to run WWII surplus Arc5 gear, your complaint that the display was off by 100hz sounds kind of funny. ?I've never owned a rig that was accurate enough to just dial in a number and have the SSB audio come through clearly.

If you have any power at all going into a dummy load, that receiver in the same room should be plenty loud. ?Perhaps the receiver is way overloaded, and is pretty much shutting down. ?Or your audio level is way down (bad microphone?) so you don't have enough drive into the final. ?A low audio level would suggest the final has not much to do though, and thus the current into the IRF510 would be stuck around 100ma. ? Hard to debug from here, anybody in the club have a scope?

John,

Sounds like you know way more than I about the USPS. ?But looking online, ACS stands for Address Correction Service. I wouldn't think packages would get sent there routinely. ?That clerk wasn't too clear on what ACS was, but she did think it meant something might be wrong with the label. ?Maybe one of those machines misread a barcode.

The NW US has had a tough winter. ?Portland seldom sees much snow, and doesn't have much in the way of snow removal equipment or snow savvy drivers. ?Whole town shuts down every time there's a couple inches. ?Just yesterday morning the streets there were a sheet of ice from freezing rain. ?I'm way out in the boonies, a 7 hour drive from Portland (on a summer's day). ?Local towns are having residents leave the taps dripping to keep the lines from freezing, the months of cold weather have taken the frost line down to the water mains. ?I'm 5 miles from our mailbox, of which I clear over a mile with my tractor, and the county's big snowplows have trouble keeping the rest open due to drifting snow. ?Makes it tough to check for packages. ?Tried driving to Portland in early December, found out in La Grand that 160 miles of I84 had been shut down from the Idaho border to Pendleton for over a day, virtually no mention of it on the ODOT website. ?Even the oldtimers say it's been a tough winter.

A couple decades ago the company I worked for was selling camera interface boards that I designed into mail sorting machines to read bar codes. ?I made several field trips to help them out ?Monstrous noisy machines, Rube Goldberg would be proud. ?The guys working on the software would send a stack of sample mail through a machine every time they wanted to test, and after a few dozen runs it would all be half shredded. ?We created a special camera simulator to drive our camera interface so they could read a few thousand images from disk, no longer needed to put on ear protection and head down to the machine room.

One for Jack W8TEE really ut it may interest others, this webpage details some boards and using them with the Arduino IDE.

Very interesting.

Well,? I've trawled through over 2000 posts and gleaned as much useful information as I can.? This version is dated and contains lots more useful info.

At this point since early January there has been around 1500 posts to Groups.io BitX20 !

That's some going for a group, just shows how popular the BitX is.

In the Raduino code are extra features which are commented out from running.? If you decide to uncomment them to use and reprogram the Nano then the wiring is as follows:-

There is code for? dual vfo, rit, cw tx/rx.

It's already in the code but commented out in the “ loop() “.? You need to uncomment them and reprogram the Nano.

It uses a pushbutton on Nano A3 pin to select using tap, press, double tap method.

Wiring colours used are

Brown = CW?? Key ?

Red? = Calibrate and CW tone output when in CW

Orange = Pushbutton to select Dual vfo’s,? RIT,? CW

Blue = PTT Sense

Black = LPF Select – not catered for yet

I am updating the Tips n Mods and will post it soon

Proper addresses, tracking numbers, they all meaning nothing when a package goes missing.? I ordered an amplifier interface cable a few weeks ago and it was scanned as being loaded on a truck headed for Colorado, and that was the last scan ever.? I contacted the Post Office, they checked, said "Yep, it's lost!? Contact the seller and let them know.".? No asking the sending and receiving ends to look for it, etc., they didn't care, it was gone and the seller's problem.? Really annoyed me.
.
For the record though, that's the first package the USPS has lost for me in many, many years.

Just three people so far. First at 19 miles, second at 12.5 miles, and third at 7.6 miles. And I could hear the third one weakly but audible.?

I mentioned before on the bad tx audio thread that the sound of my ssb signal is not as loud and clear on the SW receiver as I expected. And this multimeter reading seems to be half of the 1 amp expected. On the receiver I have to turn it up louder to hear my self with headphones than the volume the level for listening to other stations.

Some other folks reported 1V read at Q13 when having transmit problem. Mine is reading a bit more than 3V at two pins on one side and 12V on the other while transmitting. I understand this is normal operation. Just trying to narrow it down before swapping out the final.?

My first cw kit got me a official observer card because of frequency instability and chirp. Replacing the PA gave me a perfect sounding signal after that. I can't help but wonder if I got a random faulty part again. Or maybe I hurt it when the raduino freaked out. I'll just go ahead and replace it tomorrow.
