[Elecraft] Problem solved W2 power reading not functioning

[Ron D'Eau Claire]

Good news Don.

Some of those adapters are pretty flakey with widely varying output voltages
and lots of ripple on the voltage, even those supplied for use with other
electronics. Sometimes the first thing inside the electronic unit being
powered is a big filter capacitor or even a voltage regulator, while the W2
assumes a decently clean 13V supply.

Ok I found the problem with the W2, or problems.

1) The interface cable or CAT5 cable apparently was bad.

2) Power if not coming from the radio apparently the unit is not happy, I
was using the AC adaptor from my MFJ analizer as I did not have a power
cable that would fit it ready to go.

Changed the two items above and it is now working, auto range and all.

So I figured I better share.

Thanks
Don
