Re: Operation question using CW
Ashhar ?no one seems to know. It seems to use a goertzel algorithm and others have written such software as well
I stand corrected: I found this
Morse code via a PC. Which brings us to CW Decoder, a free application from WD6CNF. It can decode Morse code signals received on a radio at up to 50 words per minute,?

I learned C from K&R, too, and paid $8.95 for it back in the 70's. However, it is not the perfect book for everyone...no book is perfect for everyone. I've had thousands tell me they tried to use K&R to learn C, but couldn't. Other books, written in a different style, worked better for them. It really depends upon the individual, their preferences, and background.

..before you dive down that rabbit hole, examine the 'evidence':

Re: Operation question using CW
I think I said my CW delay at 100 or 200 ms. It’s a command line thing, and easy to set. ?You get lots of thumps if it’s too short, renting it out to whatever makes you happy.?
The cw decoder is FLDGI and I’ve never found it to be very good
There are some windows base programs that are free, we use one in our local group and it is much better than FLDGI. ?Sorry! ?I don’t know of a good one for the raspberry pie but I’m sure that one exists somewhere. ?
Since I copy code in my head, the little sBitx is a better CW machine than my 7300! And I discovered that my vacuum tube SB 200 amplifier has enough “feed around” its ancient T/R frame relay that I can just leave it in transmit on some bands and I have full break in with an amplifier then!! ?This is as good as it gets!

Quick question for the group about operating CW on the sbitx V2. I want to adjust the speed that the receiver recovers when switching back to receive from transmit.

It does help though, but then loud stations are…well, LOUD. Haha. It is like the old days of radio but with a touch screen. Haha.?
Love the little radio and I am confident this can be solved, I just dont know if it is a hardware change (like a smaller capacitor so the charge time is faster) or a software change. Does anyone know?

I'm trying to learn the C Code for the sBITX and other stuff, I found this book and figured that others may get some use out of it: It's a lot of fun, it starts you off with the standard "Hello, world"? which is basically where I'm at right now. I have been playing with it which means I try something then spend twenty minutes of looking at the error codes and using them to figure out where I messed up at. I did get it to print "Hello Earthicans, Aaron the Great was here." Yes I'm aware that I am not completely right in the head but I have fun. Before you ask here is the explanation on "Aaron the Great"? -- '72

Re: Nextion 2.8 Enhanced - How long to upload .tft file?
DaveW,
I believe you have the wrong file.? The name you gave is for an older version that was before the V5 and V6 boards came out.? Try this one on the primary Nano:
UBITXV5_CEC_V1.200_NX_S.hex
I have attached the file.
This assumes that you have a v6 board.? You did not state that in your reply.

Re: Nextion 2.8 Enhanced - How long to upload .tft file?
Evan,
I kept the factory Arduino Nano with OEM software, and original display, as backup.
The new arrangement is with Nextion 2.8" Enhanced display, and two Arduino Nanos (v3.0 ATmega328p compatible clone).
The Nextion was successfully loaded with ubitx_28_E.tft ("recent" version from AJ6CU). The display and buttons are functional.
The primary Arduino Nano was loaded with UBITX_CEC_V1.200_NX_S.hex (for I2C Meter), using avrdude (my computer runs Linux, and xloader is not available). This file is from the V5 folder. I have only used the .hex file, and did not attempt to compile the arduino sketch.
The secondary Arduino Nano was loaded with files (from compiled with Arduino IDE. ?? So far, I have not played with the secondary functions (S-meter, spectrum view, CW decoder), because the radio is not receiving.
Other notes: Before loading the CEC software, I loaded the factory software (from A.Farhan's github site) unto both of the new Nanos (compiled in Arduino IDE). In both cases, the OEM display was functional. However, I could not get either of them to do the BFO calibration (static never changed pitch). It is possible that I may have damaged something on the first Nano, or on the Raduino, because the first Nano was inserted while configured with the pins on the wrong side of the board. After correcting that error, the OEM display and buttons worked, but the radio had no reception (just static) and BFO calibration could not be accomplished. However, when the OEM Nano was re-inserted, the radio became fully functional, BFO and Freq. calibration responded normally to make minor adjustments (except that after saving the new settings, they were not retained at next boot-up).
Thank you for considering my problem.

Re: sBitx V2 SN #141 Spurious/Harmonic Measurements
I had previously made at least one measurement without the RadioShack SWR/power meter in line, ?because I knew it should have one or more diodes in there as well.?
at that time I did not see a difference, but I didn’t at that time realize there was another diode still in the Heathkit Cantenna dummy load ?system
so now I think I should go back and make measurements without the SWR/power meter in the line. ? ?
today is busy, maybe I can get that done tonight or tomorrow….
