Re: install 20x4 I2C Display - Problem without 3.3v ?
Fabian, I am not familiar with your particular display or the CEC software. Perhaps someone else can respond here after looking at the photo of your display in your previous post, and tell you if it

Re: Simple spur fix
Kees noted that you can't actually ground through C11 but rather R13- despite of my attempt to. :) I'll switch that up this evening. John KC9OJV

Re: More PA Putzing ..
Sounds like drive issues and not enough current.? Also 3:5 Turns may be a bit steep try 3:4 or 2:3. Don't forget you have the fets standing on those long legs at at low impedance loads those legs are

Re: More PA Putzing ..
Just one step at a time ....Did replace R97 and R98 (47 ohm) on the mosfets gates with 10K resistors ...Improved drive and output? And likely more instability.? Your getting more because the drivers

Re: Antenna Loops #off_topic
If you have room enough I would look to reasonably efficient wire antennas such as a G5RV, Doublet and I have seen a very cheap new small tuner from MFJ, don't remember the exact model, I think it is

Re: 45M Filters
I bought twoToycom-45E2BF from N2CBU and two T45U15BG from another eBay seller, the specifications are slightly different but at least I have selection to choose from. Thanks for figuring this out

Re: uBitx Antenna #ubitx-help
Funny Iso, I also have one that works very well too. Maybe Vince¡¯s SWR meter has had the golden screwdriver inside it. And if he ran a KW into it the diodes might be fried or the load resistors too.

Re: uBitX NANO programming issues
Hi Jim: We ran into a similar problem. "Raw" EEPROM on a "real" Nano (and most clones) is initialized to 0xFF for each EEPROM byte. However, you can't always depend on that. Our solution was to

Re: Band scan & Spectrum not working with i2c standalone and CEC -Nextion display
Marty Sorry for my belated reply. I've been looking for some new topics these days. I was also a bit busy because I was in charge of new courses. I think you have a fully equipped Standalone DSP

Re: uBitx Antenna #ubitx-help
I fully agree with Robert 'my experience of using CB meters is if they're the parallel-strip kind (very common), they may loose some sensitivity at the low end. Otherwise, they did a fair to good job

Re: uBitx Antenna #ubitx-help
Hi Gang, I just like to point out that although I only use these at HF, I have been using them for 35 years or more, they work fine! There are only a few technology used to measure standing weight

Re: HELP
One possibility is the software may be thinking you are using a paddle. Did you wire up the key with one of the resistors in series or without a resistor? When using a paddle the factory firmware uses

Re: Simple spur fix
If the filterboard replace R27 will not the two turn winding drain the DC bias CW operation to ground. Block capacitor needed?
