problem with RF receiver

[mister_e]

What about if you try slower baudrate... as slow as you can ? simple thought here because i solve many of my noise problem with that...

AND NOW let's shrink this part of your code

'*****************************************
	DISABLE

TIMER_INTERRUPT:
	PIR1.0 = 0  
	TMR1TEMP.LOWBYTE = TMR1L
	TMR1TEMP.HIGHBYTE = TMR1H
	TMR1SET=TIMER1PRE+TMR1TEMP
	TMR1L=TMR1SET.LOWBYTE
	TMR1H=TMR1SET.HIGHBYTE

	LCDOUT	$FE,$C0
	IF DAY = 1 THEN
        LCDOUT	"MON"
	ENDIF
	IF DAY = 2 THEN
        LCDOUT	"TUE" 
	ENDIF
	IF DAY = 3 THEN
        LCDOUT	"WED" 
	ENDIF
	IF DAY = 4 THEN
        LCDOUT	"THU" 
	ENDIF
	IF DAY = 5 THEN
        LCDOUT	"FRI" 
	ENDIF
	IF DAY = 6 THEN
        LCDOUT	"SAT" 
	ENDIF
	IF DAY = 7 THEN
        LCDOUT	"SUN" 
	ENDIF
	LCDOUT $FE,$C3
	LCDOUT	#H2
	LCDOUT 	#H1
	LCDOUT 	":"
	LCDOUT 	#M2
	LCDOUT 	#M1
	LCDOUT 	":"
	LCDOUT 	#S2
	LCDOUT 	#S1
	LCDOUT $FE,$CC
	LCDOUT  #REC
	LCDOUT  " "
	LCDOUT 	#T2
	LCDOUT 	#T1

	RESUME
	ENABLE

it has to work but gives you a load of delay IMO.

this is my own version

'*****************************************
	DISABLE

TIMER_INTERRUPT:
	PIR1.0 = 0  
	TMR1TEMP.LOWBYTE = TMR1L
	TMR1TEMP.HIGHBYTE = TMR1H
	TMR1SET=TIMER1PRE+TMR1TEMP
	TMR1L=TMR1SET.LOWBYTE
	TMR1H=TMR1SET.HIGHBYTE

	LCDOUT	$FE,$C0
	select case DAY
	       case 1
                LCDOUT	"MON"
           case 2
                LCDOUT	"TUE" 
           case 3
                LCDOUT	"WED" 
           case 4
                LCDOUT	"THU" 
           case 5
                LCDOUT	"FRI" 
           case 6
                LCDOUT	"SAT" 
           case 7
                LCDOUT	"SUN" 
    end select 
	LCDOUT $FE,$C3,#H2,#H1,":",#M2,#M1,":",#S2,#S1
	LCDOUT $FE,$CC,#REC," ",#T2,#T1

	RESUME
	ENABLE

and probably LCDOUT in one shot can also work

LCDOUT $FE,$C3,#H2,#H1,":",#M2,#M1,":",#S2,#S1,_
       $FE,$CC,#REC," ",#T2,#T1
