K2: with KPA500, experience anyone?

[Andrew Moore-3]

I'm interested in hearing people's experiences (good or bad) with
using the K2 to drive the KPA500.

In particular, I'm interested to hear how well the integration works,
especially regarding QSK and high-speed CW timing.

Off-list is fine.

Thanks,

Hello Andrew,
 
I connect the KPA500 with K2 via a PTT RCA cable and a coaxial jumper.  The internal frequency counter of KPA500 can detect the operating band and do the band switching.  K2 will drive the KPA500 to some 250w (key down).  Integration is straight forward as long as you have a keying device for the PTT in your K2.  K2 delivers more power than KX3 under the same supply voltage of 13.8v as measured by my LP100A.  Therefore, you will expect more power output from KPA500 if it is driven by K2 instead of KX3.

TNX & 73,


Johnny VR2XMC

Hello Andrew,

My set up is similar to Johhny, but with the cables connected from the KPA100.  I am using relatively resonant antennas, so have tuned the KPA100/KAT100 combination into a dummy load on these bands and set the KAT100 in the locked mode (sorry can't remember the correct designation) so that there is no mismatch between the output of the KPA100/KAT100 and the KPA500.

I have an emerging issue - see previous post from George NC5G and subsequent replies.
