[Heath] Heathkit VTVM model IM-13

[Kenneth G. Gordon]

Gentlemen:

Your experiences have been very interesting reading for me, and I thank you 
for them.

I have two Heathkit VTVMs, one an EUW-24. I find them to be far more 
useful on my bench than I first thought they might be.

FYI, there is an article in the latest issue of Electric Radio Magazine in which 
the author modified a Heathkit IM-18 to accept a Hewlett-Packard probe from 
their HP-410 series.

This enables his Heathkit VTVM to be, essentially, an HP-410, measuring 
RF voltages of up to 300 volts at frequencies up to 700 MHz. vs 60 volts 
maximum at frequencies up to 30 MHz with the standard Heathkit RF probe.
