Re: Frequency display refresh (or lack thereof)

Jack Purdum
 

I don't know if this fixes it, but give this a try (make a backup of your current code...just in case!). Change the current interrupt service routine to:

ISR(PCINT2_vect) {
? unsigned char result = r.process();
? if (result == 0) ? ? ? ? ? ? ? ?// New lines. No reason to check if 0
return;
? if (result == DIR_CW)
? ? set_frequency(1);
? else ? ? ? ? ? ? ? ? ? ? ? ? ? ? // No reason for else since it is not 0
? ? set_frequency(-1);
}

Then make this change:

void set_frequency(short dir)
{
? if (dir == 1)
? ? vfo += radix;
? if (dir == -1)
? ? vfo -= radix;

? // ? ?if(vfo > F_MAX)
? // ? ? ?vfo = F_MAX;
? // ? ?if(vfo < F_MIN)
? // ? ? ?vfo = F_MIN;

? display_frequency();
? changed_f = 1;
}

I can't test this so you'll have to let us know what happened.

Subject: [BITX20] Frequency display refresh (or lack thereof)

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!

As it mentions on the site, only pins 2 and 3 on an Uno are for the encoder as it is interrupt driven.? Are yours still on 2 and 3 ?

I'm assuming you are using an Uno ?? If it's a Nano then the encoder needs to be on pins D2 D3

That sounds more like a wiring problem rather than a code problem.

Re: Possible PA low output problem.

 

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?

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.

Re: USPS Tracking

 

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.

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 ?

Hi Noel!

You can sure try. Depending on the DC/DC converter you have it might work.

In my case the model I had on hand (for which I've posted the link in my previous post) generates a lot of switching noise on the 12V power line. That increases the receiver noise which is quite high from the start.

For the PA the current requirements are only 1.5A to 2 A. If it is for desk use I would use a second linear power supply for PA. If you have a 120V to 24V transformer that can deliver 2A I would make a power supply just for that.

A good option is this:

or this:

Second option has higher output current capability but you cannot adjust the current limit and the voltage is set using a multi turn trim pot.

You need to find a good heat sink for the power transistor.
