[KX2] Can the key out drive a relay?

tomb18
HiI understand you can use the key out on the kx2 to signal an external amp. In the manual, it mentions to look up the voltage and current specs for this in the specifications in the manual.However, there is nothing there. Does anyone know the rating?can it directly drive a 12v relay requiring 250ma?Thanks, Tom va2fsq.com

Yes - it's a Power FET.  From the K3 Manual:

"KEY OUT (RCA/Phono) is the amplifier T-R relay
keying output, capable of keying up to +200VDC
@ 5A."

Hi Ok,   it does mention up to 30v but no current is specified. I guess it should handle 250m ma then.
Thanks

I do not have the KX2 manual in front of me.  But I do recall the KX2
manual specification does list a maximum voltage. (I think is was in the
range of 40 vdc.) I will look it up at reply back.  The manual does not
list a maximum current.  However, my KX2 does handle the 12v relay in my
Ameritron 500m. That I use in my travel trailer.

Manual (rev A5) says 28V 150mA max (page 43).
