Michel, thanks for sharing this. I will check this out and make changes. Have you seen any other problems that should be addressed. Thanks again for sharing this issue. kn4ud

Malcolm, you have your rig looking very good. I like your case design. kn4ud

Michel, I made some changes in the scale on the s meter, give it a try and let me know how it works. Thanks for testing. kn4ud

Thanks Michel, I don't have my smeter together yet but I think I can fix this problem pretty easy. It should go all the way out to the +20, did you calibrate your s meter using Ian's procedure? I will

I agree with Jack, I have some Arduino's and clones, the main difference I have seen was price. I have windows 10 now and loaded the CH340 driver and it all works just fine. kn4ud

Yes, these are compatible. I have 2 3.2's and a 3.5 from them and they all work as they should kn4ud

Looking good Joe.. Dave, be careful on some of the bezel's, my 3.5E came with a bezel but it was just a simple cut out piece of lexan with no protection around it. Some of those out there are recessed

Enhanced has RTC on board.

Tom I almost had the 3.5 finished and my PC died. I have new PC now and I am in the process of recovering things from the old hard drive. I should have everything completed and the 3.5 posted in a few

Sorry Dexter, I'm not an english major but I fail to see the their and there you are pointing out.

All of the programming for the screen was taken from Dr. Ian Lee's 2.4 display. I did the Graphics to fit the 3.2 display. I am currently working on a version for the 3.5 display. Joe B has a very nic

thanks Jeff, appreciate it. Kn4ud

I just uploaded 4 files for the Nextion 3.2 display. They are for the basic and enhanced to work with Dr Ian Lee's CEC 1.094 firmware. I am starting to work on the 3.5 display next. I would appreciate

That looks neat..

Glad you back safe and sound Joe. Have you posted the cad files anywhere that we can look at them. 73" allen

Nextion recommends using at least 500 ma supply for their display.

Mine in the oem state with 16x2 display never got too hot to hold. went to 20x4 display and it got HOT too hot to hold added a Nextion 3.2 enhanced and it got even hotter so I am considering building

Allison What is your opinion of using varactors in the crystal filter circuit to make it variable.

Ray Thanks, I have been checking around on the optical and find that the 4.7k pullup is what others are using with the Arduino as well as an interrupt routine. I see where I also need to make some pin

This may be dumb but could you use varactor diodes in the filter circuit and vary the voltage to them to change the capacity in the circuit to vary the band width. The Electraft K1 uses this type of a
