I have an old Magnadyne SWR-72 for 11 meter (CB). I want to modify it so I can use it on 2 meter (VHF).

The only frequency sensitive components I can see are a couple .001 caps in parallel with a couple 150 ohm resistors. Can i change the meter's frequency response by changing the RC combination in the circuit?

I would submit a photo but I don't know how to attach to this message. Thanks in advance.
