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.


I assume you've tried Ramsey?

Is this the same company that makes all the kits?


I think so, but there is nothing about this model on their Web site.
I assume it's many years old, forgot to check the date codes.

I'll have to dig deeper, perhaps risk contacting them? What a concept?!

I really got it because it's small and I only need the 10 MHz range. But
this is a matter of principle!

Thanks.
