Re: Nextion 5/Enhanced for KD8CEC 1.2?
Joe Puma
¿ªÔÆÌåÓýAlso I think the Spectrum Analyzer page needs more work actually even the band analyzer. I may have been able to adjust their position and lengths of the analyzer graphs but the slider does not seem to work right with the scanned range. ?Joe KD2NFC?

¿ªÔÆÌåÓýI am attaching the HMI file. This is the version that included the graph in the main screen if you use the stand alone analyzer which includes the CW decoder. I haven¡¯t stretched the CW decoder across the screen yet, didn¡¯t figure it out yet but everything else is pretty much intact. All pages have been reworked but I didn¡¯t redo the graphics for the dsp menu, I just resized the 480x240 to 800x480. ? Joe KD2NFC ? Sent from for Windows 10 ? From: Mark Hatch

¿ªÔÆÌåÓýYes it¡¯s not friendly when it comes to resizing, and it¡¯s even worse when there¡¯s graphs involved. I have a 5¡± setup that I¡¯ve been working on keeping it as original as I can from the original KD8CEC design. I will have it available soon.?Joe On May 21, 2019, at 9:50 PM, Mark Hatch <mark2382@...> wrote:

Re: Nextion 5/Enhanced for KD8CEC 1.2?
BTW:
My respect to anybody that has undertaken this effort.? This GUI builder has got to be one of the most basic I have seen in many years. The lack of any internal resizing makes things difficult. Doesn't help that after you replace the image with the larger one, you need to tell the builder that the image is harder and expand it...? And no "anchors"/geometry management means that after you resize all the images, you then need to resize the buttons, etc. and replace them. Yecch.... Mark |
Re: Antuino
Bruce Hall
I have been playing around with the Anduino.? ?I inserted a step-attenuator between the RF input and RF output ports.? With no in-line attenuation, the measured RF output is -16 dBm.? ?As I added attenuation, the measured RF power predictably decreased.? ?The receiver bottoms out at roughly -70 dBm, and does not record levels any lower - which makes sense.? What I don't understand is the non-linear relationship at low levels of attenuation.? For instance, adding 3dB, 6dB, or even 12 dB of attenuation did not significantly change the Antduino's displayed power measurement.? Independently, I crudely measured the RF power using my oscilloscope, and the power output changes as expected.? ?I am curious what results others get with their units.? ? Why am I getting a non-linear relationship between attenuation and RF power? Bruce On Tue, May 21, 2019 at 7:52 PM Ashhar Farhan <farhanbox@...> wrote:

Re: Oldie newbie
Hi,
If the program you are trying to port has a traditional C main routine and it starts out by doing init stuff then finally has a while loop, like 'while(1){ --lines of code--};. Then put the stuff before the while loop into the "setup" routine. Put the stuff inside the while loop into the "loop" routine. The only reason not to put everything into the "setup" routine is the "loop" routine allows the Arduino code, automatically included in addition to your code, to handle the serial I/O background processing for the print and get statements used to sent debug messages to a serial terminal. And likely other tasks that need to be done.? Using the "loop" routine rather than your own while loop lets these routines to get a chance to run every cycle through your code. If your code does not use a while loop (and is not already an Arduino program using the "loop" routine, then your code may be a higher level of coding using interrupts or a real time "operating" system. In that case everything is going to go in the "setup" routine and the "loop" routine need to be there but can be empty. However, porting that kind of code to the Arduino system may be beyond what the Arduino system was built for. There are some Arduino libraries like "SoftTimer" ?that give some of the same feel to program in as a real interrupt driven RTOS. When using this library, for example, you put the things your program does in separate routines, rather than a big loop of code, and leave the "loop" routine empty. Tom, wb6b |
Re: Oldie newbie
Godz wotta pikki system! Won't even look at anything with non-alphanumeric name!? Anything with "_" is ignored. The IDE recognizes the raduino when it's plugged in - and that powers it up. I not ~/sketchbook has been created, with subdir 'libraries' - empty except a redir txt to somewhere to learn abot installing libraries. Anyone in NZ want to take way this box of junk? |
Re: Oldie newbie
Hi Dexter,
I have some questions regarding your setup. Maybe they are stupid and you already have done all these things, but the thread doesn't tell me what ?previously was done and what exactly was the (error) output. So here are my questions:? - Which version of the Arduino IDE are you using?? - Which version of the ubitx software did you clone from github?? - Have you been able to compile one of the sample programs, or the minimal sketch (named like ?e.g. sketch_may21a) ?which is automatically created when ?selecting "File new"? - If you open "File -> Preferences" Which path is shown under "Sketchbook location" e.g. /home/pi/Arduino? - If you look into above directory is there a sub directory named ubitx_20 with a lot of? - If yes, could you open in Arduino IDE the file ubitx_20.ino in this subdirectory?? - If yes, could you close all other Arduino windows except the ubitx_20 one you just opened? Hopefully your answers will help to find the problem. 73 Armin, DJ2AG |
Re: uBitx "Shadow"
As other have said it seems the BFO. You probably need to shift by at least 500hz. This picture is very similar to the one I showed to a professional vendor when I bought from them a 'fully aligned' transceiver ... they gave me money back... I am still wondering what that full meant... Il 21/mag/2019 18:34, "Curt via Groups.Io" <wb8yyy=[email protected]> ha scritto: Daniel YO8UFO op |
Re: Antuino - the antenna analyzer
I slapped one together on the bench and used 69mhz filters salvaged out of a really dead
TS830 instead of the crystals for the filters.? Tweaked the code and works well. Currently I'm experimenting with a replacement for the detector using a 1khz (really 1000 cycles) low pass amplifier as that would allow a greater frequency range than 69mhz filter. Allison |
Re: uBitx "Shadow"

Likewise I am thinking it could be your BFO setting - mine was way off when first delivered.? If you listen carefully to SSB you might come to same conclusion that it may need an adjustment.? Instructions are available at HFSignals - BFO adjustment tends to be easier than frequency calibration.? also see this guide at my local club: ??? ubitx calibration INSTRUCTIONS Raj also brought up the topic of spurious - I have a v4 also.? In a typical v4 there are spurious issues in some of the bands, generally not much more than 10 dB out of compliance.? In mine I installed a circuit board containing a set of 3 relays, to separate input and output relay function.? it fixes spurious at 18 MHz and below (unfortunately the board and kit are not for sale anywhere yet!? I have dropped hints to ubitx 'merchants' to sell it).? my rig was okay 'as delivered' on 80 and 20 meters.? (I have not yet solved spurious above 18 MHz - they are from a different source - Raj I remember uses better relays and some shielded inductors - I am not sure what else.? I am wondering how the shielded inductors will work in conjunction with my relay solution - I need to get some to find out!? other fixes did not work for me without reducing CW output power).? Enjoy your ubitx - I recommend 20 and 80 meters from what I have experienced with my rig for spurious. ?? Curt |

Thanks Robert!
Removing the AGC confirms it was not installed correctly. Going to reinstall the AGC in a couple days after I add header pins to the main board to allow for a more stable and secure connection. That should stabilize its operation, and give me a chance to solder it in correctly.? Also, I went back to my old callsign that I had held for over 30 years. CW muscle memory has returned!!?
