OK, KX1 nervous Nellie question testing the 80-30 board

w1pns
Hi Folks,

I've just installed the 80-30 board (filter left to go), and in making
the final current and voltage checks, I was unsure if one reading was
too high. If the current draw after the LED times out is between 34 and
37 ma, good. If it's much higher than that, it could indicate a short.
How much higher?

I got a reading of about 38.9 ma. The various voltage checks all were
fine, between 4.8 and 5 vdc. So I presume those are OK. It's the current
measurement that I'm a bit concerned about.

Any thoughts, other than I need to chill?  ;-)

With best regards,

Pete

Pour yourself a glass of wine and finish the KX1 tomorrow Peter. :-)
You're totally within the tolerance on the components, supply voltage
... and your meter.  All of the Elecraft resistance/voltage/current
checks are designed to be essentially obvious unless they tell you in
the manual, and then they become very specific about it [generally in
the areas of VCO voltage ranges, and the like].  You're cool, you can chill.

You are going to have a blast with your KX1!

Pete,

That does not sound excessive - it is within a 10% range.  The current
draw on 80 meters will be a bit higher than other bands because the
relay on the LPF board is not a latching type, so it must draw current
when 80 meters is selected.

Many thanks, all. I've had fun with in on 20 and 40; it's nice to
finally be adding the second two bands!

With best regards,

Pete
