Gyula, Rafael,

Thank you for taking the time to answer my question about GridTracker. I truly appreciate it.

Thank You. 73,

Me, but of course I designed it. ;-)

the only issue that I know of is that there is a slot cut out for the potential meter board for the ribbon cable. The problem is if you use that slot, you will install your potential meter upside down with the tuning knob on top.?

the other issue is that the build volume for that case is very large and will not be printable with the popular ender 3 printers. ?

My 3 days old sBitx? running from my Samlex SEC1235M started exhibiting problems. Strange behaviors seen on the display,? tuning? or other functions locked, too many
to describe. After switching to a Bioenno it was working fine. The power supply was still with its original factory set voltage. It was 13..9v while the Bioenno was showing
about 13v. After adjusting the Samlex down to 13.2v the sBitx is now stable.

What is the file that contains the logbook data for the sBitx v3 and where is it located?

Absolutely!? I've mounted the encoders in a box with a PTT and mic input so i can tuck the board itself out of the way.

good day. please tell me how to add USB (like /dev/ttyUSB0) rs232 ptt interface support for my amplifier.

Thanks for what you have done so far JJ.? If it's not fun, then take a break, that's what I'm going to do this weekend.?

Have a good one with your family JJ.

This code expects the I2C bus to be kernel I2C interface. Make sure you have one of the dtoverlays in /boot/firmware/config.txt

For loading the I2C Bit-Banged (BB) driver in the appropriate sBitx pins, with kernel RTC clock driver loaded (for use as system clock, this is what I use):

dtoverlay=i2c-rtc-gpio,ds1307,bus=2,i2c_gpio_sda=13,i2c_gpio_scl=6

If you just return(NULL);? instead of return (millis()/1000l) + time_delta; the problem should go away. I don't know why time_delta is used if there's a RTC and the RTC is synced with internet time servers.?

Thanks Jerry. I will test it and see if the issue goes away. I think this is just more garbage code that wasn't removed from the file for earlier versions of sBitx hardware. That is the unfortunate issue that frustrates people and why HF Signals has a poor reputation.

EUREKA!!!

I was able to reproduce the problem.. After I entered a different gridsquare, the time is now off by an hour. I think there is a bug in the sBitx software.. I can now troubleshoot this further.

I changed my timezone to Australian and added a gridquare for Budapest.

Thank you Pete and Gyula. I feel bad that there are still issues with it and am frustrated about it. I want to give you a better experience than you received from HF Signals. I will continue to work on this issue over the weekend and try to find a way to resolve it. The challenge is that I do not experience the same issues here and cannot reproduce it. That makes finding a resolution very difficult.

Could someone else chime in and provide feedback on whether or not they are seeing the same issues? I would like to narrow down if it is an issue for other timezones or outside the US.



Thanks,
JJ

Hello N4GW,

The two encoders are on a separate board as described on the HFSignals page:

Buy a fully tested sBitx-v3 board with the heatsink mounted. Build your own customized sBitx for fun and hacking.? Included are:

1. A fully tested sBitx-v3 board with heatsink mounted
2. 32 GB SD card loaded with the sbitx software
3. Tuning/Function encoders mounted on the front-panel PCB with the connecting cable
4. XT60 connector with wires to connect to the power supply
5. M3 mounting nuts, screws and stand-offs
6. Power switch with leads to plug into the PCB

You will have to supply your own box, display, mouse, keyboard,? microphone and Raspberry Pi 4 or Raspberry Pi Zero 2W

Hi, I was thinking about getting the V3 board.? I want to use it with an 11 inch display, so was curious about how the multi knob and VFO were attached.? Are they on a separate board.? If they are on the main board then I guess a 11 display would not work, unless they would be easy to remove from the board and attach them to a different case

Hi Elmers,

I have a nicely built Hendricks Bitx20 v1.3 I bought at a hamfest.??

The power plug out (female) is the wrong size to my power supply battery pack, male plug.

I have a Rockmite, that has the right Female power supply plug out, (as a donor plug) I need to know which wire goes where on the NEW ROCKMITE PLUG to swap out plugs.

I'm not a techie, does anyone know the correct wiring??

The Rockmite donor plugs has two SMALL soldering points at the very top

is the right Positive or Negative???? (the bottom 4 dots I believe are hold down solder points, I think??)

Can someone help me swap out plugs?

Is the RED Wire in the Bitx20? POSITIVE?

Thanks for your expertise.

Has anyone used the 3D printed case from Thingiverse?

The issue isn't with the shaft lengths of the encoders. the problem is that they use the threaded body of the encoder to mount the board to the case.
unfortunately, the height of the connector against the panel is greater and the board is bent when they attempt to tighten the nuts. Since they cannot properly tighten the nuts, Everything is under tension and the stresses are transferred to the base of the encoders. Mine began to skip and show erratic steps and now the tuning encoder only works when it wants to.?
I removed the tension from the board and the tuning encoder began to function again, but I assume it is damaged now.?
