In case I did not mention it earlier, I tested the sw circuit with a DMM and pressing the switch sends D4 on the Nano to ground. Tomorrow, I am going to test the pulses with an oscilloscope. Dennis

Voltage on the + connection of the KY 040 measures 5.07vdc To: SoftwareControlledHamRadio@... From: SoftwareControlledHamRadio@... Date: Tue, 5 Apr 2016 18:22:53 -0500 Subject:

Gary, Thanks. Yes, mine has a pcb (it is a KY-o40) and I am feeding 5 vdc to it. To: SoftwareControlledHamRadio@... From: SoftwareControlledHamRadio@... Date: Tue, 5 Apr 2016

No. All he's saying is that you need to run a line from 5V to the '+' on the encoder. You can take the 5V from any of pins 7, 8, 9, 10 on J1. Jack To: "SoftwareControlledHamRadio@..."

Dennis, Does your encoder have a small printed circuit board like this? These are the common KY-040 encoder. You may also have the encoder without the pcb. If you have this type, run a line from 5 Vdc

Gary, Sorry, that was over my head. I am working to understand microprocessors in general, and Arduino in Particular, as fast as I can. I have amassed a significant amount of knowledge over the past

WA4GLI, You might also try enabling the Vcc line to your encoder. According to the library internal pull-ups are inlace but I had a similar problem and that cured my issue.

Thanks. I have downloaded this file several times and it always drops the h extension. I don't know why. Will try your code To: SoftwareControlledHamRadio@... From:

WA4GLI, I didn’t have any issue and my library shows Rotary with the ‘h’ extension, as it should. I suspect you somehow got a corrupted download. Included is the listing for Rotary.h /* * Rotary

Hi! Regarding the LC Circuit that goes on Y1. The QST in depth document calls out Cx as a 150pF and the instruction manual from Farrukh's link calls out a 56pF. I was clarified by Jack that the

Hi! My kit came with 5 band color code resistors versus the ones referenced in the instructions which are 4 band color code resistors. I thought this may help somebody save some time deciphering the

Gentlemen, I have eliminated everything except for a code issue. If any of you: 1. Built a DDS VFO using the QST article instructions and 2. Downloaded the rotary files from Brian Lows github, and 3.

I have a red and a gray toroid. Clearly not black so I'll treat the gray one as black.. Biggest problem I have is that my DDS-VFO kit arrived missing parts.. Sent an email this morning to Farrukh

When you run into an unknown like this, try using Google. I typed in: "green toroid vs black toroid" and found a web page that tells exactly what it means. It turns out that green is usable up to

Hi! FYI My 49-er kit came with one red and one green core toroids. The instructions call out a red and black core. I'm assuming in my case the red is red and the green would be the one they refer as

All: I live close to a 50KW AM station and my Forty-9er does a great job of picking it up. I have an article coming out in CQ that is a broadcast interference filter for the AM band. That article,

You don't need to have it in a tab. Simply make sure the library is installed in the libraries subdirectory where you installed the Arduino IDE. The #include directive at the top of the source code

Now that we have eliminated wiring and hardware problems (I even tried using different Nano and DDS boards), I wonder if this could be a sketch error. I downloaded the Rotary.h file from the web site

This looks fine... Jack, W8TEE To: SoftwareControlledHamRadio@... Sent: Sunday, April 3, 2016 7:26 PM Subject: [SoftwareControlledHamRadio] Re: Increment Problems ? I have double checked

Dollar to a donut it's a BCI filter. It appears to be between the BNC connector and the antenna jack of the Forty-9er. Also, I have a 50KW AM station just down the road and my Forty-9er picks it up
