Re: Farhan's Analog Again The Daylight Radio
Really disappointed in the receiver of this project. After many attempts to cure microphonics issues with the BFO, etc, the RX has more noise from the mixer/bfo then band conditions during a local thunderstorm. There is no difference between the noise floor with or without the antenna. Removing the output from the second mixer, the audio is dead quiet. Once the mixer/BFO is connected the noise is bad. Reminds me of an old tube receiver. It does receive signals that are very strong and they sound mediocre. At night, WWV is always in the background. Tick, tick tick, beeeep. I think once the noise issue is resolved, this will be a neat receiver but untill then I won't build the TX. Anyone else who has constructed the radio have any problems? Barry

Where can the .STL files for the 3d printed plastic toroids be found?
The PTO VFO one I have found easily. But the toroids are proving more elusive.?
Or is that left as an exercise to the homebrewer??
I have the audio chain built and starting on the product detector and BFO, so I'll soon get closer to the VHF, TX filters and the RX band pass filter and the toroids become more relevant.?

Re: Signal leak on both sideband. UbitxV6
@ Rolan,
I did not try your version of firmware as I already had a loaded arduino with N8ME firmware. I will try your firmware also once I get a new arduino.

Re: Signal leak on both sideband. UbitxV6
Thanks everyone for your inputs,
The problem appears to be resolved after calibration and switching to N8ME firmware (VU3GAO mods).

Good description?in below link:
Signal Meter Type (Option) : none : Analog Meter using A7 PIN? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? : _S? ? : I2C Signal Meter using I2C Port
If you are adding a second arduino and including a I2C signal analyzer for s-meter, cw-decode, etc then use the _s? version.?? If not adding a second Arduino -not building a signal analyzer I2C (including if you are just building your own simple s-meter) then use the version without the _s.
See section 1.1 for a list of options - the full text is very much worth reading.?
I just added the Nextion and used the version without the _s and then added a simple s-meter (LM386 version) and it all appears to be working fine. Jim? K5KKB
In github, the ZIP HEX files, for V5(6), there is .200NX.hex? and .200 NX_S.hex
I am using Nextion 3224K028.
What is the difference between the NX and NX_S? versions of these HEX files?

Mark,
the tft you have listed gave me the "file number too small" error. I compiled from the hmi and the new tft is OK.
John

John,
Happy it worked for you! Unless you modified the original .hmi, I "should" have the tft on the github already generated from the original .hmi. However, if you see I am missing it, you can reply to me via private groups.io email here or I am also good on QRZ.

"Discovery" and "Intelligent" Nextion Screens for KD8CEC now added to github
Had a few hours this Sunday and added versions of the KD8CEC screens for the Nextion Discovery and Intelligent screens.?
You can find them for either the "Original" KD8CEC provided screens or "User Contributed Screens" at:
Check the "recent" subfolders. There are "no legacy" versions of this screen (in fact the LTS can't generate code for these screens.)
As far as I can tell...? The "Discovery" is an upgrade to the "Basic" and the "Intelligent" is an upgrade to the "Enhancement". So my recommendations for new buyers would be to purchase the Discovery or Intelligent versions, Discovery is probably fine, but has a slower GPU, and more limited memory that might make future upgrades to more enhanced screens problematical.
All I did was to recompile existing .HMI files for these new screens.
I do have a 4.3" Intelligent screen and this works fine. But I don't have all the Discovery and Intelligent screens for a formal test. So my recommendation would be to buy a Discovery or Intelligent from a firm with an easy return (i.e. Amazon) as a safety net. I *do not* believe it will be a problem, but better to be safe here.
Also as a reminder, none of the KD8CEC screens of 3.2" or greater are scaled to full screen. If you decide to use them, there will be black boarder and you will not be using your full screen. The User Contributed Screens are all full screen.
I am interested in any experiences in trying to use these screens. And if you have a ".hmi" file that you do not see on the github, please let me know via either private groups.io email or my email that is on QRZ.

Mark,
I found the listings I was looking for. Message #89884, Jim W0EB, Dave WD8AJQ and N8ME.
Appears these were to address using non-graphic displays. Most issues addressed with Nextion display offload.

Mark,
I am done. I have a current tft file and loading the display went well.
If you would like a copy of my tft file let me know where to send it,
I am now looking for some updates to KD8CEC system. I think I read that an N call made some changes.

Re: Signal leak on both sideband. UbitxV6
When you touch the USB or LSB buttons on the screen, the stock software does not actually tune to the sideband due to a bug.? When you touch a sideband button, turn the knob to tune the frequency slightly off then back to the desired frequency and the sideband will then be changed.? I fixed this in my own version of the software (and made several other changes).? ?If you are interested, you can check it out here:??

Thank you, Mark
I DL the 28_E_.HMI file. I have the current editor installed.
I hope to learn how to build the tft file from YouTube.
