K2 and KPA500 Keying

[WD6DBM]

I took the ptt line from my K2's K160RX board. Can I run this straight to my KPA500 and key it QSK?

Thanks

Eric,

I trust you meant the Keying signal on the K60XV instead of the K160RX -
yes, that will key the KPA500 just fine.

The KPA500 keying requires sinking only 1 ma. and the open circuit
voltage is only is less than +16 volts.
The 2n7000 in the K2 can sink up to 200 ma. and can handle up to +60
volts, although I would de-rate it to about 75% of those values just to
be safe.

73,
