Software Controlled Ham Radio
Hi everyone. Welcome to the Software Controlled Ham Radio discussion group. We have received overwhelming response to the PCB offer in support of the 'Modular 40m CW Transceiver with VFO' article in

Re: New file uploaded to SoftwareControlledHamRadio
I've read through the PDF file Gary submitted and he has some great details in it...definitely worth reading for anyone who has built (or intends to) the Forty-9er. Thanks, Gary! 73, Jack, W8TEE

Make your own PCB's
All: I've been wanting to try a new technique for making PCB's but never got around to it until now. The first time heard about it was via a series of YouTube videos by Charles Adams, K7QO. He calls

Increment Problems
Guys, I am using the sketch for the DDS VFO downloaded from QST with the encoder switch connected to Pin 21 of J1. Pressing in the encoder switch does change the increment value. However, when I
By dennisstage@... · #72 ·
Re: Increment Problems
I think it needs to be connected to pin 17 of J1. Pin 21 goes to D7, but we want pin 7, which is actually D4. Look closely at the schematic provided from Farrukh's site. Jack, W8TEE

Re: Increment Problems
Jack is correct, switch from encoder needs to go to pin 17. 73 Gary W5GW

Mystery board??
Can anyone let me know what this small green pcb is between the 49'r kit and the DDS-VFO?? See it in this image link.. http://www.farrukhzia.com/k2zia/40m-modular-CW-TRX.jpg

Re: Increment Problems
Sorry, I should have provided more info. I originally did have it on pin 17 as per the schematic. In that config, the frequency changes, but the increment is frozen on a single value (pressing the

Re: Increment Problems
I have double checked the rotary encoder connections and here is what I have: Switch: Pin 17 Clock: Pin 22 (D3) Data: Pin 18 (D2) GND: grounf +: 5vdc

Re: Increment Problems
FYI: I have tried several new encoders-same on all.

Re: Mystery board??
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

Re: Increment Problems
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

Re: Increment Problems
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

Forty-9er BCI Filter
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,

49er Inductor windings
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

Re: 49er Inductor windings
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
