Re: Need help downloading/installing required software for 49-er
Jack;
I printed the DOC file above and tried to work through that today; no luck, because of my inexperience with computer downloads, files, and such things.? I was confused too, on installing the "non-standard libraries, that are found at the top of the AA source code file."
I was able to upload the "blink" sketch successfully though, but that is it.? After the blink sketch, I was looking for the rotary encoder sketch, to test that component, and I was not able to find it.??I?know that that I have a lot of required files missing.
With that being said, would it be possible for readers of this forum, that were successful on their build, to somehow supply me with the necessary software for this project, on a thumb drive or Arduino Nano, let's say; I can supply one or both of these items to the volunteer?? Otherwise, I am really going to be stuck.? With good working software, I'll then know for sure if I have any hardware/wiring issues in?my build.?
Thanking you all in advance, I am, Karl, KO8S

Re: Need help downloading/installing required software for 49-er
Wow!? Thanks Jack, John and N0ngq for your responses to my (this) thread.? I can see now, that I am WAY over my head with this required, downloading of software.? For example, I tried to download the recommended sketch that would determine what liquid crystal display that I have.? I tried that, and in compiling that sketch, I got an error-stray # in program line 30, #include wire.h?
John advised that I increase the brightness of the display, and perhaps that would show characters; it got bright with adjustment, but no characters, only squares.? Also, I noticed that the back of the display board has a red LED lite when powered up.?
At this point, I will take Jack's advise and seek someone in the Detroit area (I do not belong to a radio club at this point of my life), or perhaps someone on a local repeater, that can help me with this software for this project.? Better yet, someone that?has completed this projected successfully.?
I feel quite confident, that my soldering and wiring is accurate, although, there is always a chance of error.? All components are mounted in my homemade case and I think that it looks very, very nice!? If I can find a way to attached a photo or two here of it, I will do that next.?
Regards, Karl, KO8S

Re: Need help downloading/installing required software for 49-er
Also, it is common for the constructor that creates the LCD object to be overloaded. For example, the code from our project uses:
LiquidCrystal_I2C lcd(0x27, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE); ?// Create LCD object and set the LCD I2C address
which is different from many constructors. You may have to experiment a little before you find what matches the display you are using. As a rule, if I'm buying something new on the Internet, like a display, I always ask the vendor which library the device uses. If they can't answer that question, I look for another vendor.

Another thing to watch for is the?LCD I2C address "(0x27, 16, 2)"?in line 99, I have some that are 0x27 and others that are?0xF3. I marked the address on the PCB on the ones I have.

Re: Need help downloading/installing required software for 49-er
Hi Karl The solution could be that you haven?t adjusted the display contrast! On the backside of the display, there is a small (blue?) potentiometer. You have to adjust this, when you see the 16 squares on the display. When you adjust the potmeter, the squares will disapper, but hopefully you will see charaters instead. Adjust for best readability, and forget all about it, hereafter.

Re: Need help downloading/installing required software for 49-er
First, make sure you have the latest version of the Forty-9er software from Farrukh's site:
?www.farrukhzia.com/k2zia?
Second, there are non-standard libraries that must be installed in the libraries subdirectory of where you installed the IDE. You can find any missing libraries by doing a search on the #include files:
#include ????????? // From Brian Low: https://github.com/brianlow/Rotary #include ? ?// Shipped with IDE #include ? ? ? ? ? ?// ? ? ? ? "
// Get the LCD I2C Library here: // https://bitbucket.org/fmalpartida/new-liquidcrystal/downloads // Move all *_I2C files into a new folder named LiquidCrystal_I2C // in the Arduino library folder #include
Note that there are a bunch of libraries that use the same name, but are actually different. For example, the #include is NOT the same as #include ...case makes a difference! Put the correct libraries in the libraries subdirectory.
The fact that Blink works means you've installed the IDE software correctly. The fact that the rig doesn't work, unfortunately, could be hardware, software, or both. Just because the code compiles without error does NOT mean you're using the correct libraries. Check those first.?
If that doesn't work and you belong to a club, see if one of the members can help you track down the error.

Gentlemen:?
With the hardware all connected, I powered up the Arduino from my computers USB port, and the LED on both the Arduino?and DDS board lit up as well as the blank (16 square segments only) liquid crystal display.? I then uploaded the?"Blink" sketch, and the LED on the Arduino blinked away.? I then uploaded the Liquid Crystal?sketch with no change.? I then looked for the Rotary.zip file and I was not able to find that in my downloads, so I suspect, I have done something wrong in downloading both of these files.? I will have to confess; downloading software and getting it running is new to me!? The hardware part of this project, I feel that I have done pretty good at.? So gentlemen; what steps can I take to go on from here?? Thank you all in advance, de Karl, KO8S

ok I have built my radio kit and the dds vfo and when I power it up everything looks good.? I can get the display to change the frequency and when I key it make a nice sound a bit loud but nice sound.? problem is I am not getting any signal into or out of radio.? I took it to one of my elmers just to check the output frequency and there was none and no signal was herd.? I have been back through board and looked for solder bridges and check the correct orentiation of the diodes and Capacitors and also looked for cold solder joints.? I am not seeing anything that looks to be wrong. I did have the filter that we had to make up for the receive in opposite from the picture but I have fixed that and still nothing.? any help would be appereciated.?? Thanks?? Nathan?? K7NDM

There seems to be problems with the encoder switch connection. I am puzzled by this because the schematic clearly shows the encoder connected to D4 on the Nano. The problem is that people don't seem to understand that D4 IS pin 7 on the Nano. Look closely at the schematic from Farrukh web site at the file labeled:
dds-vfo-assembly-manual-rev2.pdf
If you have not downloaded the assembly manual and code from his site:
?
you should do so before building the Forty-9er.

Re: Power supply for the transceiver
So I decided to check the actual current draw to be sure I had a decent choice. ?I prepared a 50 ohm resistive load for the antenna, plugged in my ear buds and set the supply voltage to 12.0 volts with my bench supply. ?I put my Harbor Freight ?vom in as an ammeter and observed the current to be .14 amps on receive and .54 amps during transmit.?
Noticing that my fat fingers had put in .3 amps when the math really was .39 amps (I had intended to round it to 400 ma and didn't notice the typo), and that I thought that would be safe, I needed to correct that. ?My actual draw was bigger and probably since different parts of the circuit are involved and there must be efficiency stuff to consider, I should have expected something higher. ?.54 amps is higher but not as high as was obtained with the 13,85 volts and below the specified limit of 750 ma on the cord.
I think the cheap cable sold on eBay is not a bad choice. ?I am waiting for it's delivery so I can see the actual voltage but it lets me use a bunch of battery backups that I have for phones, etc ?and they can be charged from the usb outlet on my car, my generator,my charging station, etc. It may be a better idea to use higher voltage for the power but it is not a bad choice for emergency use.??My thermoelectric stove lamp can run the transceiver so I can run my system if I just have firewood. ?Not bad but probably a bit extreme for an idea.

It worked beautifully.? Thanks.?? However to get rotary push switch to work, had to change from pin7 to pin 4.... Now everything works.? Tnx agn...? KJ4ZI

Re: Implementation of the voltmeter option
I asked the same question when I was coding the warning system. As always in amateur radio, it depends. ? My SLA batteries fully charged give me 12.7v. Setting the lower limits to 11.7 and 11.5 would probably work. Tweak the upper limits to 12.8 and 13.0 ? However if you want to run it with a conventional power supply of 13.8v then the upper limit numbers mentioned above would not work. Here 13.9 and 14.0 is not out of reason. ? In the end I just pulled numbers out of my aft end and let the end user decide what limits are appropriate for his rig, situation, and usage. ? Till later Hank K5HDE

Re: Implementation of the voltmeter option
My thought is that 13.5VDC is perfect for 2-3w output Brian. And to go easy on Q5, What is the output at 13.5V? And did yo use a heat sink??
Although the D882 transistor could be pushed further in PCM and proper cooling, 3w is adequate, QRP I Just drive up Mt Washington, connect?a piece of copper wire with a micro-tuner ?... ? ;)
Anyway, yes, power increases with Vsup but you must keep the output swing within rated maximum to avoid distortion. The D882's absolute max rating is 30V Vceo . Q5 wants to double Vsup,?so some margin helps keep the output in the linear region albeit class C. ? ?..jim-ab1br ?
