I have an original Cobra 148GTL CB Radio. I know that i can modify it to
operate in the 10Meter band by switching the crystal to a 11.6908MHz
crystal.
is anybody familiar with this mod? If so, how do i determine what
frequency each channel will be at? will i need to purchase a freq.
countert o determine what freq. will go with what channel? Also, will my
102: whip work with 10M, or rather will it give me a close enough SWR to
suffice, or will i need to purchase a new antenna?
Any information or assistance would be greatly appreciated.

There are channel conversion charts out there so you can roadmap your
radio freqs.
The antenna will work on 10. Maybe not at optimum performance, but it
will work.

I suppose if you call 5 inches too long acceptable without a tuner, it will.
In real life, the radio will not be happy.

You're probably right, but I don't have a whip on any of my vehicles now
to go play with this and see what readings I can obtain but I've taken
an old mobile Galaxy up on 10 on many occasion with no any adverse
effects with either transmit or receive and I'm sure someone on 10 would
have gladly let me know if something was amiss. Only thing missing was
the cw. Oh, and I wasn't at the high end of the band or running any
power other than the radio. I still swear by those old Malaysian boards
for heartiness...4 X 4 the hell out of them. Maybe I'm just lucky.
