[Johnson] re: Ranger driving Thunderbolt attenuator

[David Harmon]

A light bulb would probably be as good as anything....ugly though.

If it was me....I would look at the Dale series of 50~ power resistors
and after checking the price would more than likely use the recommended
Johnson attenuator.

If you have an old Heath Cantenna, you may be able to modify the scope
jack to provide an input to the Thunderbolt.

Hi everyone.  I have both the Ranger and Thunderbolt.... both in good
working condition.  I have the diagram for the Johnson attenuator using
about two dozen resistors, but before making it up, is there any other
'simpler way' to reduce the drive the Ranger and still get positive peak
modulation along with the required drive for the Thunderbolt?  Any
suggestions or comments will be appreciated.  Thanks from Ron VE4SR in
sunny Manitoba, Canada.
