(W1) W1 Power/SWR Meter Question

[stan levandowski]

Will I harm my W1 by leaving the W1 Power slide switch in the "on"
position and turning the meter on and off with my station supply?

I'm asking because the tiny slide switch seems rather fragile and using
it perhaps several times a day is sure to eventually break it.


I noticed that when I power the W1 off with the station supply, the
green LED slowly decays; when turning the W1 off with the slide switch,
the same LED goes out immediately.  That suggests that the
microprocessor is involved in shutdown.


I know that all Elecraft transceivers require an orderly shutdown via
their onboard processors.  Does this apply to my W1 also?  Am I looking
for trouble here??


Thanks and 73,
Stan WB2LQF

Stan,

That orderly shutdown process only applies to the K3, K3S, KX3, KX2, P3,
PX3, KXPA100, KPA500, and KAT500.
The rest of the gear that Elecraft produces can be powered on/off with
the station supply with no ill effects.

I rewired mine so that it is always on when connected to external 12V, and
the switch just switches the battery into the circuit for portable
operation. I

 was always killing the battery by forgetting to turn it off when I powered
down the station, this takes care of that problem!

When you turn off the switch on the meter you are cutting power.

When you turn of the PS you are probably watching the PS Caps bleed down to zero (hence the fade)
