[Elecraft] K3 to KAT500

[Johnny Siu]

Apart from Jim's advice below, I would supplement as follows:

1.  If you have no intention to take K3 as portable use or your K3 is a station rig, I would go for KAT500.  This will give you the future liberty of buying a KPA500 or other linear amplifier.
2.  Once you have a linear, the internal KAT3 tuner will become redundant.  In fact, I sold the KAT3 to subsidize the purchase of KAT500.  I am using KX3 for portable use.

Some folks feel the need for an AUX cable to tell the KAT500 what band 
it is on. I don't, because the KAT500 has a very fast frequency counter 
that can figure that out with a short burst of RF.

Yes.

Yes. To prevent damage to its relays, the KAT500 must be able to 
interrupt the keying line to any power amp that is used.  It has an RCA 
input, and an RCA output. So ONLY if you're running an amp, you need an 
RCA-RCA between rig and KAT500, and another between KAT500 and power amp 
PTT.

> Is there anything I'll be missing with the KAT500 vs the internal tuner other than portability?

QRP autotune  -- the KAT500 is optimized for high power, and doesn't 
autotune very well below about 10W.
