FM Transmitter Setttings? Dip Switch

[somedude99]

Hello, I'm just wondering, I been searching for 2 weeks online now for a dip switch freqency chart to program my FM transmitter. I figured someone might be able to help me here. Its a 120 watt transmitter with a exiter board made by DB Electronica . The Company that made this transmitter does not exist no more but the transmitter istself is not old and in great shape.

The transsmitter freq is programed by 2 sets of dip swtiches of 8 each So a total of 16 swtiches. The freq programmed into it right now is 99.3 and this is the switch patern now: ( DB Electonica board)

10101100 10011011

I cant seem to find a bin patern that would make this = to 99.3 ?

I need to change the fequency to 104.7 FM

If any one would have any info on this it would be great

thanks

Change the lowest switch in one of the banks and measure frequency.

Than put it back and do the same for the other bank.

Post results here.

Ok its been figured out the bin order is reversed and the swtiches are reveresed as well. I put in :


10011000 11101011 = 10470 flipped lol

And got my frequency of 104.7 on first try


thanks

Yes, just flipping one switch and measuring result usually tells you
what is going on. Its easy from that point on.
