Jack At the risk of giving away some content that may have been better saved for your column, I was talking about the pseudo dumb terminal that is part of the Arduino IDE. To the best of my knowledge

... connected... Man, I hate this laptop keyboard...

Evan, The AGC board I installed is at this link which shows how it is conjnected to the uBITX PCB. https://shop.kit-projects.com/index.php?route=product/product&product_id=101 73, Justin B. KI5GKD

Hi Arv: All of those would be interesting, but I don't know anything about BitLash other than what it is. Usually, a device being used as a screen (e.g., 16x2 display or TFT color display) will have

All, So the reason I wanted to upload sketches is as follows: I find the tuning of the uBITX troublesome. Say I'm at the top of 40M and I want to get down to the CW segment: I spin the knob, and down

Jack Of course I would be interested. I might even be able to contribute some problems and maybe some solutions for the column. Things that immediately come to mind: - How to do a Screen Clear on the

Hello, I’ve read a lot about the isolation of analog and digital masses and their star connection. For me and for the digital masses, I see at least 4. The arduino, the SI535, the Nextion and the

Woo hoo! It worked! I also changed the code a bit - added an extra printout just to convince me that it had actually uploaded. I was fooled because the IDE didn't display anything like "upload

Even and Ashhar - The middle leg of D5 produces a small "squeal" (about the same level as that of pin 3 of the amp) as well so maybe everything is OK.? As soon as I find my USB cable I'll

Jerry: What happens if you try to run the following code: char message[128]; void setup() { ? // initialize serial: ? Serial.begin(9600); } void loop() { ? int charCount; ? ? // if there's any

*** Yes, I have that. - Jerry

Now on a different PC. Results the same. Yes, the CH340 driver is loaded. Anybody know what's the baud rate? Playing with the Serial Monitor at 9600 baud, I type "hello" into the "send" box and it

I'm late to the conversation, but I'm assuming you've installed the CH340 or CH341 device driver, right? Jack, W8TEE

Also, under the Tools --> bootloader Atmega328P, you will likely need to select the "Olde bootloader" option if you are using a clone. Jack, W8TEE

Justin, The fact that you are away from AC power lines (I am assuming that is the reason for the solar panels) would mean that any tests that rely on AC hum may not work.? The loud "squeal" when you

Jerry, I would go to the Windows Device Manager (right-click on the Windows Start Icone) and verify that the CH340 driver is connected and the com port assigned.? It should show up under Ports (Com &

At least on Linux, this sometimes happens to me. No real solution - just turn on the arduino and upload the firmware fast (between 1 to 3s). It works for me. Rafael V6.

Are you using the Nano as it appears you have multiple hardware solutions? "I did this with the teensy4.1 Arduino clone. I don't know how it works with the Nano firmware, but imagine it's similar. -

Justin, I believe that Ashhar Farhan is referring to D5 in the product detector stage.? That goes through the preamp Q70. Where did you tap into the audio chain to get the signal for the AGC?? Could
