Jim,
If the relay requires 100ma I would be hesitant to connect it to the KX3
without additional information.
The reason is that the pull-in current can exceed the nominal current
rating - so check the specs carefully.
I would trust it if the current meter check shows a current of 50ma or
less, if it is as high as 100ma, I would not take the chance. Remember
that the digital current meter will not show the pull-in peak.

I believe the relay in the AL80 12volts at 100 ma. I think it does draw
a bit more than that, put your meter in line the keying relay jack and
see what it draws. I certainly would not want to key the older AL80
with a KX3. Jim K4JAF

Subject: [Elecraft] KX3 To SB1000 Amplifier
Hello AllI just ordered a New KX3 (Kit)I am wanting to know if Keying My
Heathkit SB1000 (Ameritron AL80A) amplifier with key line off of the
ACC2 will be a problemIt says that it is good for 30v @ 100ma. My
Amplifier is 12v relay. Not sure current. I would think itwould be fine.
But just wanted to check. I won't be able to order my KXPA100 till next
year. Have to save the penny's for that one.Thanks
