Thanks Jack, I just ordered that same offer on Ebay, now I have to wait!? I'll check them all first before I solder them to the PCB!? de Karl, KO8S

Thanks Wayne, I am finding the same problem with the mini-360 soldered on my board. I had bought two kits from Farrukh so I tried the other mine-360 out of the circuit and it read about the same as

Thanks Hank, that is what I thought but I wanted to be sure. With a close look at the bottom of the board, I can see where the two solder points are joined for the C8 connection. Well, I connected C8,

The Arduino IDE places every new program in its own "sketch folder" as a way of organizing files. If you load up the IDE and click the File --> Preferences menu sequence, the first thing you see on

Hi Hank, Why does Arduino want your new rev. 6 file in a sketch folder and what is that? I'm a newbie... Thanks, Jim AB1BR

I see where there can be some confusion. A picture is worth if not a thousand words then at least a couple forum posts. On page 4 of the VFO assembly manual is a photo of the populated VFO board. The

I have populated the Nano DDS VFO PCB that I have from K2ZIA with the last component remaining; the C8 capacitor 100u-25v. In looking at the PCB outline for the placement of C8, I see two outlines for

I think your values are fine. Use symbolic constants for the voltages at the top of the source file. Then, if someone is unhappy with the voltages, it's easy to change them. It's important that, even

This first version of the voltmeter just displays the voltage. In the next version I'd like to include undervolt and overvolt cautions and warnings. I'd like to get a consensus from the group as to

On the VFO board are components R7, R8, and C7 going from the 12v bus to pin 26/A7 of the Arduino. The intent of these components is to provide a voltage divider so the Arduino can sense the input

Hi Don, I have your address as: N5DM USA Donald J Mayhall, II 835 Merridel Houston, TX 77024 USA

Use J3, not J2 and adjust to about 12v on AC voltmeter. DC reads about 7 volts. The output should be set to 4 volts peak to peak AC with a scope. Cheap voltmeter reading should do. I may have read a

I got all the parts needed from a small company named Debco I think. Cheap and fast. On Sunday, June 12, 2016, bnwidmaier1@... [SoftwareControlledHamRadio]

Bob / K3JOP, Send me an SASE and I will mail you a 22uH choke for the 49er filter mod. I had to buy a 'lot' from China for mine. They seem fine but I give no warranties! QRZ.com address is good. Don /

Hi Ivan: First, make sure you have downloaded the doc files from Farrukh web site. We sent QST a set of new files before the article even appeared, but they apparently have not used them. Use the

This project appealed to me almost immediately after seeing it in QST and I thank and congratulate the authors on a terrific project. I am not a computer guy nor an engineer and am a complete newbie
