I have the below code and it's work
I want to change to work for FM 88-108MHZ
How i can change it;

Hello Savnik!

I try to send You PM but You didn't answer.....I'm working on same thing and I saw that You have found some code fro TSA but on upper band....

Did You try something to do with it or?

I think we could do this.....it seems to not be a problem!

I have changed it to work for FM 88-108MHZ. Of course, you have to make it work for 250KHz, 500KHz and 1MHz steps

Hello Jerson!!!

Thanks for work!

But i have smaller errors about it, if You please can explain I doing something wrong or?

regards!

[Marin]

I've set this code to work from 87 to 108 MHz......but I have problem:

When I press UP it goes ok from 87,0 87,1 87,2 87,3 87,4 87,5 87,6 87,7 and thjen jumps directly to 88?????? And whole time like this on whole band to 108MHz, up or down....

everytim it steps ok from 100,0 to 100, 7 with step of 0,1 and then after 100,7 directly step to 101,0......I don't know why jumps over 100,8 100,9????? This is on whole band I just took 100 as example.


this i the code:




DEFINE LCD_DREG PORTD
DEFINE LCD_DBIT 4
DEFINE LCD_RSREG PORTD
DEFINE LCD_RSBIT 1
DEFINE LCD_EREG PORTD

Change the line for calculating F3 as shown



F3=(100*F1)//8

[Marin]

HI....I try but that i only get 0,4 steps.......


F3 = 100*(F1//8) with this code I've got steps with 0,1 but when come to 0,7 directly jump to 0????

[Marin]

Also,.,,,,whats // means?

[Jerson]

Marin

I have PMed you. If you have the code working by now, please post it here to complete the thread.

Actually all this codes have step size of 125KHz....and we here want to do a 100KHz step size....

So fisti thing to do with TSA is to change quartz to 3,2MHz because then it can be programed with step sizes of 50KHz which is good!

Another question is to change the code and do the PIC xtal must be changed?

bueno un gran saludo para todos soy marcelo de chile y quisiera ver si me pueden ayudar con un tsa 5511 y pic16f84
prara la banda de 88 a 108 mhz por favor gracias estare atento
