Anyone ever seen this? It's a cute little frequency counter that
is supposed to go to 1.3 GHz, but only the 10 MHz and 60 MHz ranges
work. The 1.3 GHz range is either non-responsive or erratic.

There's a house numbered chip, which may be the prescaler: 2-8758-229
with 274-227 below that.

Any info appreciated.

Thanks!




I assume you've tried Ramsey?

Is this the same company that makes all the kits?


I took high school electronics shop with a John Ramsey,Kenmore,NY.
He was making FM wireless mikes at the time.
