Cobra 148/2000/Grant XL

I will try to put this in an easy to follow format

Tx side

C46 Change to 2.2uf mylar/polyester film or non-polarized electrolytic
C101 Change to 1.5uf tantalum 16 to 50 volt
C102 Change to a 910pf ceramic disc
C104 Change to 2.2uf tantalum 16 to 50 volt
C108 Change to 1uf to 2.2 uf tantalum 16 to 50 volt
C174 Change to 10uF electrolytic or tantalum 25 to 50 volt
I found that if you have a very deep voice start with 1uf on C108
and work up if need be.

If you need more highs on tx Change C 105 to .001 to .0001uf mylar/polyester film The smaller you go the more highs you get.

RX

C71 Change to 1uf mylar/polyester film or non-polarized electrolytic

C75 Change to .01 to .001uf this will give you more highs on rx
optional
C76 Change to 2.2uf mylar/polyester film or non-polarized electrolytic

C182 Change to .01 to .001 for more highs on rx and tx
optional
C183 Change to 2.2uf mylar/polyester film or non-polarized electrolytic

C187 Change to 2.2uf mylar/polyester film or non-polarized electrolytic

With C75 and C182 you can start with no Change to them, then if you feel you want more highs then change them out


Thanks Goldfinger for all your help!!
