When you say road map on this radio I'm thinking it has 40 Channels low and above the normal CB 40 channels. if so here:
Low 26.515-26.955
Normal 26.965-27.405
High 27.415-27.855
What works better then a road map and saves time is a good Freq. Counter.
Copper sells them and here are a couple.

Waffle,
Depending on which modification was performed you can use the link below to figure out the coverage of your radio with a little help from a friend or frequency counter.

Position 1: sw1 down, sw2 down
NORMAL CHANNELS
Position 2: sw1 up, sw2 down
15=26.815 20=26.885 25=26.925 30=26.985(ch3)
16=26.835 21=26.895 26=26.945 31=26.995(ch3A)
17=26.845 22=26.905 27=26.955 32=27.005(ch4)
18=26.855 23=26.935 28=26.965(ch1)
19=26.865 24=26.915 29=26.975(ch2)
Position 3: sw1 up, sw2 up
1=27.605 6=27.505 10=27.555 14=27.605
2=27.455 7=27.515 11=27.565 16=27.475
3=27.465 8=27.535 12=27.585 20=27.525
4=27.485 9=27.545 13=27.595 23=27.575
5=27.495
Position 4: sw1 down, sw2 up
1=27.605 11=27.725 21=27.855 31=27.955
2=27.615 12=27.745 22=27.865 32=27.965
3=27.625 13=27.755 23=27.895 33=27.975
4=27.645 14=27.765 24=27.875 34=27.985
5=27.655 15=27.775 25=27.885 35=27.995
6=27.665 16=27.795 26=27.905 36=28.005
7=27.675 17=27.805 27=27.915 37=28.015
8=27.695 18=27.815 28=27.925 38=28.025
9=27.705 19=27.825 29=27.935 39=28.035
10=27.715 20=27.845 30=27.945 40=28.045
if you have the FULL, 3 switch mod:
SW 1& 2 down, sw 3 up
37=27.415
38=27.425
39=27.435
40=27.445
if the person who modded the radio used the radio switches....find somebody with a radio capable of receiving these freqs & try xmitting in different switch combinations til you figure out what is what. like starface said, the galaxy/texas ranger $60 freq counter is more then sufficient to get you in the ballpark of where you need to be. |

Thank you everyone for your input, i figured out normal channels has 3 switches total. Will the FC347 Plug in Freq Counter work with this older radio? It doesnt have any connectors to plug in |

No, you need a passthru counter (connects inline). The FC347 is for the new rangers and such.
Depending on PLL it could be modded several ways.
U858 or MB8719 chips. Oldest would be U858's. |
