Here are some code snippets from a project I did. It calculates SWR from the voltages read from analog pins A6 and A7. It does a number of other things, so here are the basic pieces of code for SWR

*Hello everyone and thank you for the work. I will want to know if someone has made the firmware for Nextion 3.5 with CEC 1.097. Thank you Michel*

Correct, no meter provided. A DVM is sufficient. Or could go into analog pin A7 (with an analog switch to select forward/reverse) of the Nano.? Perhaps both A6 and A7, use D0,D1 for the keyer if you

Allison, the instructions are pretty terse.? Looks like the meter/meters does/do not come with it.? How does it work?? Use a DMM to measure forward and reverse voltages and do the math in my

Bill, I guess you are right.? I ought to be able to do some experiments before we leave to get a sense for how the MFJ performs at low power.? If I can understand what readings correspond to 2:1, I

this will save a lot of people a lot of time. -- 72 and God bless KD4EPG

I agree, John. I just found this. I think it ought to be on the website, readily available to all. I wish I had had it weeks ago.. -- 72 and God bless KD4EPG

I have modified the CEC Nextion screen for my 3.2" 3.2 Enhanced HMI https://drive.google.com/open?id=1BwHgaScL0lGLMs9l_hC2UMzTafX_nKDS 3.2 Basic HMI

I'd? like to thank Jack and Tom for their reply as once I loaded the CH340 driver, I was able to upload 1.28. Jim W6yxy

UPDATE I found the low receive was due to a bad NANO. I have a spare Raduino board and put it in and it worked, replaced the NANO on the other Raduino and it worked. Problem now is? I have no XMIT

The new discussion group has been formed. [email protected] Three persons have volunteered to be moderators (Gilles, Dennis, and Jim). I will make them moderators just as soon as they have

Your results are disappointing as I'd suspected they would be. The amplifier chain seems ot struggle to make power and the quality of the power is poor. What also is suspect is the two IF stage 12 and

I have a v3 uBitx that has had some issues in the past but these were all worked out, to include changing out the TDA2822 to another version of that chip. I have been working with this radio for

Quick answer: Michael, you can set that frequency range anyway you want. It’s been along time since mine was stock, but I think it easily did the 40 m band. I quickly took information from others

I built my Bit40,? but was looking to find some specifications.? Is there a good list of specifications???? The HF Sigs site has some for the uBitx but missing on the Bitx40.?? For instance

Hi, If I recall correctly the forty meter filter also passes 30 meters, and the 20 meter filter includes 17 meters. The materials are starting to arrive for my external filters and I intend to build
