SWR Meter for WFC/VIC??
« on May 11th, 2015, 05:27 PM »
So, I started messing around with old CB radios in my car again.  While refreshing my memory on how to tune the antenna with an SWR meter, I got to thinking.  This seems like a tool that we need for VIC tuning...  An SWR meter is set for a 50 ohm system, but can we build one that will work with what ever ohms we want to use?  How many volts does an AM CB radio put out at 4 watts?  Can we build a 50 ohm VIC and use a CB SWR meter? 

Also if the wires connecting from the VIC to the cell are as important as the coax going to an antenna, shouldn't we use a coax style cable?  A CB antenna also needs to have a certain length of cable between the radio and the antenna.  Could this hold true for a VIC system?

If we could get some kind of dedicated test equipment for this type of system, it sure would take much of the guess work out of it.

I would have thought that a voltmeter, prefeably one that which can take a beating, would be enough to let you know how well the cell fares with regards to being tuned to such a frequency that which yields the highest possible voltage across the cell, or gas output if you will, for the (secondary) circuit at hand.

The way I see it, one of the problems would be how to measure cell voltage without interfering with the inductive and capacitive components in the circuit, atleast not all that much anyway, regardless of what measuring method you'd use.

It's an interesting question though, no doubt about that.
