KX2 with KXPA100

[Phil Hystad-3]

I plan to acquire the KXPA100 to use with my KX2 while at the home station.  Usually, I use my KX2 QRP in the field but I thought a 100-watt boost would be nice sometimes.  It is backup to my full K-Line.

Since I also have a second KAT500, I plan to NOT buy the internal antenna tuner with the KXPA100 (at this time).

The Fred Cady document describing the KPA500 and KAT500 describes an interface scenario of the KX3 with the KXPA100 —> KPA500 —> KAT500.  This configuration shows the need for a key line connection between KAT500 PTT relay and the KXPA100 (in addition to KPA500 which I will not be using).  Also, a keying cable between a KX3 to KXPA100 adapter and the KAT500 (which are part of the KXPA100 cable configuration kits that I will also be acquiring).

Is there anything other than described above that I need to know to support the KX2—>KXPA100—>KAT500 configuration?

Phil,  There is a different cable from the KX2 to the KXPA100.  It is an accessory as I recall.  The difference between the KX2 and KX3 and KXPA100 are different cables.  Other than that, the KXPA100 interface to KPA500 are the same for both radios.  How do I know this... I have done so myself.  I have used both the KX2 and KX3 rigs as backup.  The KX2 is now relegated to portable.

73,
Bill
