During the Mexico City earthquake disaster, we tried to get a Kantronix
packet interface going in Mexico City for health and welfare traffic.
Unfortunately, during the short time we had to test it, we couldn't
get it to receive anything. The manual was singularly uninformative
about troubleshooting. It appears that the FSK work is all done by
a magic chip which has no description in the book and a custom
part number. We couldn't find any pin that appeared to have the
FSK demodulator output.
Does anyone know how to tune this beast up with a scope, rather
than just using the frequency counts? Does this thing work? Is it any
good? Does anyone at Kantronix know how to write a technical manual?
+++FLAME ON+++
We wasted several hours of valuable disaster net time due to the
sorrowful documentation on this product!
+++FLAME OFF+++
What should I tell Carlos (XE1HC)? Should he throw the thing
away or is there a rational way to get it to work?
