Re: BitX40 from the grave

Vic WA4THR
 

Follow up on this, now that the hay crop is harvested and in the barn and I have a little more time. I have another working BitX40, so I swapped the replacement Raduino for the one in that radio and had exactly the same symptoms...it acts like it is working, the display shows tuning steps as you adjust the pot and it seems to go into transmit, but no signal can be heard other than white noise and no signal is heard on transmit, either. Putting the original Raduino (both with the Amunter sketch installed) back into the rig returned it to full functionality. So I believe I just got a bad Raduino. Since the programming "took" and the display is working normally, I suspect it may be the SI5351A chip...because there really isn't much else on that board. I've sent a note to HFSignals.

Hi again Peter, 
If you want to leave the S-meter input connected to the A7 pin on P5, and can work with the IDE to change something in the source code for V1.57 (or any previous version), go into the ubitx.h file and change line 33 from #define SMETERREADPIN  (A17)   to #define SMETERREADPIN  (A7)  this will allow the S-meter to take it's input from A7 instead of A17.   Of course, you'll have to re-compile & load the changed firmware - (sorry about the idiot lesson, LOL).

Your choice, you can either move the wire, or re-define the pin.  Actually, that's why we keep the firmware open source and provide the source code for all.

Hi Jim,

Is there anything special that needs to be done to get the smeter to work, I have the kits-projects AGC and when I try to connect its smeter header to A7 it doesn't seem to work. Check on voltmeter I can see variation in voltage depending on signal strength but it doesn't seem to make any different to the smeter in the UI.

Best regards, Peter.

This is working properly now. What are the bandwidths of the crystal and LC filters?

Hello Jack,

Go to this site:
Thank you so much!  If I knew what it was called before, I probably would have found that, but I am VERY grateful for the link!  Thank you! :-D

Hi Gary,

RGB565 format, right?
I just wanted to convert an RGB or 'standard' hex colour to whatever the Arduino format was, and now I know what it's called thanks to you and Gary! :-D

Thank you both so much! :-)

Re: Need color format help #ubitxv6

RGB565 format, right?
So do you have RGB888 colors you want to convert or just need a widget to look  at what (close) the colors would look like on your screen?


Re: Need color format help #ubitxv6

Jack, W8TEE
 

Go to this site:


and click in the "middle color bar" between the two boxes to get to approximately the desired color. Then start clicking in the left box for the "refined" color you want. The right box shows the value you selected and the hex representation is in the textbox above.

Re: KD8CEC firmware upload question.

Bruce W4BRU
 

Progress being made. It turns out the command line copied and pasted was missing all the - (minus) symbols! This time it's complaint is:

"avrdude: No AVR part has been specified, use "-p Part"
 
Valid parts are:
  uc3a0512 = AT32UC3A0512
  c128     = AT90CAN128
  c32      = AT90CAN32
  c64      = AT90CAN64
  ...etc. but the list includes 
m328p    = ATmega328P

So the -p is valid. I'll dig around for more.


Re: KD8CEC firmware upload question.

Bruce W4BRU
 

Thanks Evan. From your guidance I changed it to:

avrdude ­p m328p ­P /dev/ttyUSB1 ­c arduino ­b 57600 ­U flash:w:/home/pi/Documents/BitX-Pi/Firmware-upgrade/UBITX_CEC_V1.200_16P.hex

I got this error:
avrdude: no programmer has been specified on the command line or the config file
         Specify a programmer using the -c option and try again

(Note dev/ttyUSB1 is correct,dev/ttyUSB0 is my HF rig.)

I decided to read the avrdude documentation. Apparently the "programmer" is "arduino" but it can't find it. Neither can I. I expect is supposed to be on my system in a file. I have the Arduino IDE installed but have never used it.


Re: uBitx20 Power Supply

Gary Anderson
 

Hi Bill,
Not having the pull-up resistor on the keyer could very well put the v5 into TX mode right after power up.
(which would be the case on a normal v5 build when you 'disconnected all cables interior to the rig ')

What are the ratings of your power supply?
If you don't have a lab supply with programable current limits: Recommend a 1A fuse to uBITX to test initial power-up and RX. (then replace with a 3A fuse before TX check-out)
Also recommend connecting your dummy load as protection if board is going into TX due to an error.

Check that you wired up the 3 lead power connector correctly.

Rgds,
Gary


Re: Latest Firmware for the TSW Teensy 4.1 Raduino Clone Kit #ubitxv6

Jim Sheldon
 

Hi again Peter,
The "A7" in the software manual under S-Meter should read A17, not A7.  I didn't catch that as I actually connect it to the rightmost pin on the Encoder plug in all my versions (this WAS A7 on the old NANO version, but is connected to the A17/D41 pin on the Teensy 4.1.  That might be why it isn't working for you if you connected it to the A7 pin on the P5 header, pin 8.  

Hope this helps.  I'll fix the manual and send you a copy straight off.

Check the wiring to A17, not A7 on the Teensy 4.1 .  Looking at the rear of the ENCODER plug, it should be the rightmost pin (the old A7 but it connects to A17 on the Teensy).

Also, S-Meter needs to be turned on in the SET menu as well as that same menu item's decode value should be set to 24 for the Kit-Projects AGC.

Please download & use the latest firmware version from the website as well - just uploaded V1.57 last night.

Re: Specan Yet Again

Dave,
If your distortion is not going down by 12 db when you reduce the tones by 6db, this only means that the IMD products were present in the two tone generator, they are not the result of IMD of the specan. With the ADE1 mixer, your IIP3 should be over+15 dbm.

A two-tone test at -20 dBm is shown below.  The distortion is 57.4 dB down, so IP3 = 8.7.  Interestingly, adding a 6 dB attenuator results in distortion 63.7 dB down for IP3 of 5.8.  Not sure why IP3 should worsen with reduced input?

With a -20 dBm single tone input, some harmonics are visible in a wide sweep.  Something in the signal chain is right on the edge of distortion at -20 dBm.  Any thoughts?

Thanks for your help.  I've learned a lot in this build.

Bruce,

I believe that you have an issue with the above command line.  I think it should be

avrdude -­p m328p ­-P /dev/ttyUSB0 -­c arduino -­b 57600 -­U flash:w:UBITX_CEC_V1.200_16P.hex

That is assuming the hex file is    flash:w:UBITX_CEC_V1.200_16P.hex 

I would use the file manager to verify the file location. Then replace the flash:w: with the correct path to the hex file.

If you did not set permissions correctly, then you may need to add a sudo command at the beginning of the command line.

I have not done this, just going by the instructions and reading what you copied into the message.

BTW, \u00ad is the unicode character for -.  It also appears that you have the command in multiple times.

Good luck in finding the problem.
