Re: Device i2c address 0x57 and 0x5f?

 

Thank you for the offer.? I do not use my DE portable, so I always have a network connection to sync time.? I have other projects pending, so I will put this on the back burner.

So you should get rid of the i2cbb.c in case you want system I2C. It is an easy change. I can help, in case you want RTC as system clock.

Rafael,

There are three devices on the DE i2cbb bus:
1 - The Si5351
2 - The RTC
3 - The SWR/PWR meter (if added)

I believe that the v2 is the same.? I do not have one to verify (I have found discrepancies on the DE schematics, so I do not trust the v2 schematics without a v2 for reference).

I am not sure that it is worth the effort to remove the i2cbb bus.? To have the RTC on the system, adding a third bus may be the easiest.

Again, thank you for the information.

I completely replaces i2cbb.c, unless you want to keep some i2c bitbanging for the Si5351A (are they in the same i2c bus?). What exactly is your setup in the DE? The RTC is in a different i2c bus than the Si5351A?

Hello Rafael,

Thank you for the information.? It will take me some time to digest it.

One quick question: Does this replace the i2cbb.c bus, or is it added to allow the RTC module to connect directly to the system?

Hi Evan,

Hello Gyula,

Thank you, I can read the pdf.? If I understand correctly, to make it work on the sbitx, you would need to modify the sbitx code to remove the i2cbb.c code and change the calls to the second hardware-based i2c bus in addition to adding the config.txt change.

I will try implementing the system based i2c-2 on my test RPi and see how it works.? If successful, I will look at the changes required to implement on my DE.

Thank you again!

I just removed fake_hwclock package here.

I let the RTC set the system time and modified sBitx to just use the system time and not do anything with the RTC. I also installed and configured chrony to set the time from a USB GPS dongle, if available. My sBitx will automatically work with three time sources (4 if you count fake_hwclock) and set the system time from the best one available. By using the system time, the same time is available to all programs.

Re: ubitx

 

According to the photo it's 160-10M
Maybe the owner fitted a 160M LPF to use it on Tx.
You can receive on 160 but you need a LPF to Tx.

I meant normal ubitx originally designed by farhan vu2ese.?
Re: ubitx

 

It is a normal ubix? ver 3,4 or 5 with kd8cec firmware. You can get details of said firmware at? ubitx.net.

Re: Edit the Log

 

Correct. sBITX stores the log info in an sqlite database.? The sqlite browser mentioned here /g/BITX20/topic/99777967#103269 will let you view and edit the log database.
The python tool mentioned will query the log database and write out the log in a ADIF format file that you can load into another logger, including LOTW.

I believe the log is not a discrete ASCII file log, but is instead kept inside the sqlite database.? the "log tools" mentioned likely provide a convenient interface to manage those tables in the database.

I'm glad it worked out !? ?So I just wonder, are there any unique features of the N8ME software that you find particularly useful or better that the other versions that you have tried ?? ?
