[Elecraft] SP3 ISSUE

[Edward R Cole]

Experience!
Back in 1980 I was beginning my new career as two-way radio tech 
working in a BLM radio shop (had been mw engineer in old career in 
CA) and asked help troubleshooting from a "50's oldster".  He told me 
that most new-young techs make the mistake of looking for high-tech 
problems when most "troubles" are simple.

So check:
1.  power source; signal input/output - first  (that includes cables 
and connectors)(and test equipment-meters)
2.  Control settings (pilot error stuff)
3.  Look, Feel, Sniff (often the problem will be very evident to 
those senses)(that hot blackened thingy)
4.  Then get out the schematic and repair manual
5.  Call customer service (not always step five).

Of course if you ARE customer service then ask the "old guy" ;-)

Just yesterday two old trusted test cables went "open ckt" and a 
trusted coax went high SWR.
My spectrum analyzer that "seemed dead" had a switch in the wrong position.
If voltages seem wrong check the ground wire.
Experience!
