I'll make the measurements tonite.

I wouldn't unsolder them yet, until you're convinced they're bad. Check the voltage on the base and collectors of the transistors. I can't remember the voltages you should see on the collectors, but

Ah - you are on to something. As best I can measure, I see no output from either transistor. Its hard to believe that both are faulty, but should I try to replace both of them? Last time I tried to

I just uoloaded the CH341SER zipped driver for windows 7 and the "non recognised" serial/usb port on the Arduino boards. Hope folks find this useful. Wayne - NQ0RP

Jack, I "second" your motion! U doing Field Day? Listen for K4WC here in Concord, NC. 73, Bo

Karl, nice to see another "old timer" still at it! I'm 76, still having a great time (between the pain pills). I got an early start at 14, so I may have an advantage. Don't give up on it, you will

Hang in there, Karl! This "software stuff' can turn out to be a lot of fun. I'm 73 and still learning new techniques every day, and I think that's what keeps us around! 73,Jack, W8TEE To:

Thanks Wayne for your offer; I'll?just wait for my 10 pcs to arrive from China, as I am not in a hurry to get this build up and running with all of the summer activities that?I will be getting

Thanks - I did see your post on measuring the VFO output.Unfortunately, I do not have an oscilloscope to see that aspect of the output.However, per your suggestion and measuring with my DVM, I get

Check the buffer transistors. What are the voltages on their pins? Jack, W8TEE To: SoftwareControlledHamRadio@... Sent: Sunday, June 19, 2016 6:11 PM Subject: [SoftwareControlledHamRadio]

Correction to prior post. Installing the proper .ino compiles just fine, and the voltage on the LCD indicates 13.8 v input from power supply. Still no significant voltage from J3 or J2. Ivan - WC2S

Thanks for the suggestions. Since my original post, I reset the rotary encoder pin positions according to those I saw in W5GW's VFO checkout, and I think this question has been resolved. I also

Thanks for the advice Jack. I ended up uninstalling Arduino IDE and reinstalling which assigned COM3 allowing communication with the Nano board. I was able to upload the new "Sketch", with Hanks

There are device drivers in the directory where you installed the IDE. There are two EXE files and you need to run the one that pertains to your system. Intel or AMD.) The COM port can change, so try

If you are using Windows then you will need a driver for the USB interface chip. This is not specific to the Nano but is used by many other microcontrollers. The driver that is built into Windows is

It apparently needs a cap. R Jack as my prg would not compile until I capitalized "R" in Rotary... It compiles but I am unable to address the board with the laptop. It is not finding the com3 which I

I just finished an article on making your own PCB's and used my BCI filter, a dummy load, and Lou's (W2ROW) offset as the example. I posted a photo. The dummy load is made up of eight 100 ohm, 3W

When I downloaded the program, it prepended a minus sign at the start of the filename. That needs to be removed from both the directory and the *.ino file. Second, the Rotary header file is a lower
