[Elecraft] DVM Resistance and Continuity Tester

[Steve & Anne Ray]

The discussion on DVM and measuring resistance reminded me of a neat circuit
I found to build a Continuity Tester.   I built this a while back this when
working with some Solid State Circuits and also used it building my K2 to
verify I had good connections on the Toroids.  Thanks to it I did not have
any PTTR, (Hi N0SS).  The following is the link to it.

I built it like the schematic, but rather then build the multi vibrator
circuit (T4 and T5), I cheated and used T3 to drive a Sonalert.  Nice part
about this tester is you do not need a On/Off switch.
