I am in the process of building a K2 with the 100 watt amp for another
ham.
He also needs to drive a linear. I also apologize as I have not looked on
the website. Can someone point me to some information about this so it will
be linear ready when I get it done?
Unless the linear requires you to switch a negative or AC voltage on
transmit, the KPA100 is probably all set to drive a linear. Here are
the specs for the amplifier keying interface:
PA KEY output
Compatibility DC relay coil, pulled to ground
(do not use with AC-controlled relay)
Current 1 A
Voltage 200 VDC
The switching is all solid-state and quite fast, so the K2 can directly
drive a QSK linear with no special keying circuitry. For slower relays,
you can set the delay to semi-QSK.
