Re: [Elecraft] K2: with KPA500, experience anyone?

2012-10-22 Thread Mike Walkington 
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.

[Elecraft] K2: with KPA500, experience anyone?

2012-10-21 Thread Johnny Siu 
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

主題︰ [Elecraft] K2: with KPA500, experience anyone?
  
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,
