{done} how to change the band cut-of frequency?

Hi OM, YL, SWL's
my direct question is, at which part of programmer software I can optimize the band cut-of frequency's for my own need like region-1 exactly! Second, I have extended license in germany to work for BW & THW in a spezial part of 60m band. I want to configure the firmware by my self for my personal commitment. Thanks for all information to this topic, bro.
I setup on MacOS High Sierra the eclipse software and compilers too. I can build whiteout errors a firmware file on my system now. But, I don't know on which part of the whole project I have to do my changes. I need you to get it done, thanks.

The goal is to optimize all amateur band cut-of frequency's to region-1 and activate the differences on the band I have to work on the extended license management for the emergency radio activities (THW).
The last step is to build many more different fw files every for the event I do, like sota gma activities in only ft-8 or others modulations to get fast and simple in action;) But this is future, first I need to know how to optimize the bands I need.

Dir Dirk,
as I'm working with Linux, I look inside .h und .c
Files for pattern FREQ (lower & upper case -i grep parameter)
cd UHSDR-active-devel/mchf-eclipse/basesw/mcHF/
find . -name \*.h -exec grep -i -H 'FREQ' {} \;
find . -name \*.c -exec grep -i -H 'FREQ' {} \;
UHSDR/UHSDR-active-devel/mchf-eclipse/drivers
find . -name \*.h -exec grep -i -H 'FREQ' {} \;
./ui/ui_configuration.h:#define EEPROM_BAND0_FREQ_HIGH <<== perhaps the right place!
I found the ui_configuration.h file with BAND defines.
But it seems that this are binary values directly for the freq. synthesizer chip to programm.

Hi Markus,
first thank y for answer.
Oha.. I think I have to do a look but on point, we need the exactly informations how to change. I also suspect that inside the complete jumper labels and environment variable in use to define. But this is just my first impression;)
Ok.. back to the point. How and where I optimize the cut-out frequencies for alle the bands. In the actually firmware I can't find just one band is right for region 1 :-D How ever, let's fix this up together, I'm just a loan in programming but a specialist for hf engineering.

Dirk,
a more important thing to take into consideration are the HW filters (BP and TP)
inside the mchf which have to be adapted for you needs.
So it's not only a sw issue to move the rx/tx frequencies but hw issue too.

Hi Frank,
right.. this looks like I want to optimize for region 1.
Can anybody other confirm this?
PS: Markus, sure.. but first I want only optimize the correct cut's.

Hi,
of course, the way we do this, it is possible to implement region switching in a fairly simple way, just define multiple bandinfo sets (one per region, with the default one being the one we have today). However, things changing the number of bands would need further investigation to be sure this is not going to cause problems. Eventually, of course, not a real problem, just more work.
Although I would spend a little more effort to integrate also the name of the bandInfo into the data set. Also more work but pays off.
Just like this (and some more changes like settings in the config menu, not shown):
// IARU Region 1
const BandInfo* bandInfos[] =
{
{
{ .tune = 1810000, .size = 190000, .name = "160m"} ,
{ .tune = 3500000, .size = 300000, .name = "80m"} ,
{ .tune = 5351500, .size = 150000, .name = "60m"} ,
{ .tune = 7000000, .size = 200000, .name = "40m"} ,
{ .tune = 10100000, .size = 50000, .name = "30m"} ,
{ .tune = 14000000, .size = 350000, .name = "20m"} ,
{ .tune = 18068000, .size = 100000, .name = "17m"} ,
{ .tune = 21000000, .size = 450000, .name = "15m"} ,
{ .tune = 24890000, .size = 100000, .name = "12m"} ,
{ .tune = 28000000, .size = 1700000, .name = "10m"} ,
{ .tune = 50000000, .size = 2000000, .name = "6m"} ,
{ .tune = 70150000, .size = 500000, .name = "4m"} ,
{ .tune = 0, .size = 0, .name = "Gen"} ,
},
// IARU Region 2
{
{ .tune = 1810000, .size = 190000, .name = "160m"} ,
{ .tune = 3500000, .size = 300000, .name = "80m"} ,
{ .tune = 5351500, .size = 150000, .name = "60m"} ,
{ .tune = 7000000, .size = 200000, .name = "40m"} ,
{ .tune = 10100000, .size = 50000, .name = "30m"} ,
{ .tune = 14000000, .size = 350000, .name = "20m"} ,
{ .tune = 18068000, .size = 100000, .name = "17m"} ,
{ .tune = 21000000, .size = 450000, .name = "15m"} ,
{ .tune = 24890000, .size = 100000, .name = "12m"} ,
{ .tune = 28000000, .size = 1700000, .name = "10m"} ,
{ .tune = 50000000, .size = 2000000, .name = "6m"} ,
{ .tune = 70150000, .size = 500000, .name = "4m"} ,
{ .tune = 0, .size = 0, .name = "Gen"} ,
},
};
