Re: Homebrew satellite control system that can run on sBitx
The homebrew satellite antenna controller boards arrived and a prototype has been built and I have it now controlling a G Dash 450ADC ?quite nicely from gpredict?
?
unfortunately thesbitx /transverter doesn’t seem to be sensitive enough (without any preamp) , but I think I just heard the beacon from AO – 73 using an older ICOM – 820H?

Re: Mike Black W9MDB SK
Thanks Ken, N2VIP for keeping an eye on what's going on.
Unfortunately, many people ignore all respect and understanding regarding the deceased amateur.
Unfortunately, this policy comes from the street and spares no one.
I thought about calling the questioner's attention, but who am I to instruct him in order. A 74-year-old old man who knows how much time he has left, because our fate is not only influenced by our actions.
For me, Mike, W9MDB helped a lot at the end of December last year, when I asked in another forum how to eliminate the error message 'Error in SoundInput'. Since then, with his help, I can use the jtdx program on sbitx without restarting.
So my thanks go to Mike, which I did back then in response. ?

Re: Mike Black W9MDB SK
Hello Rick,
?
There are two versions of the Nano's boot loader: one for original miniUSB-connected devices and the other for USB-C devices. This is a generalization, so there can be exceptions.
?
The secret is to change the processor in the tools menu:
?
?
If one does not work, try the other.? All of the USB-C Nanos use the ATmega328 processor.
?
The other potential issue is the size of the bootloader file.? If the KD8CEC program will not fit, some options are selected in the ubitx.h file:
?

Not selecting the FN_WSPR frees up the most memory. The display plays a role as well. There are two suggested feature lists:

Setting define to 0 removes that feature from the program.
?
I hope the above helps.
