[Elecraft] K3 & KPA500 3 days in.

[r miles]

My K3 is 2.5 yr.s old. I never bothered with updates as I was happy with 
the radio as is. When my friend WB4YDL  helped me get the amp going we 
had to run the latest updates. There is a new one that must be run to be 
able to use the amp. I am using the Elecraft interconnect cable.
.....
I discovered that after we had the KPA500 up & running my ATU TUNE & ANT 
[ant 1 or 2] functions were off in the K3. I  had to go into the MENU & 
turn on  those functions. They are back & working OK. I don't know if 
this is just something that  happened  because I had never updated the 
K3 or if that happens to all connecting the KPA500. It did not affect 
the RX ANT function.
...
One curious note. My SWR on the 6m antenna is apx 1.4:1. Good enough for 
the amp. I tapped ATU TUNE with the amp off & the K3 easily went to it's 
normal  1:1 SWR. When I keyed the amp the SWR LEDs  are showing  apx 
1.2/1.3:1 SWR.  The K3 reads 1:1 SWR either way.I don't know if it 
actually is that or what. During xmit with the amp it shows better SWR 
consistantly. Haven't tried the HF antennas yet.
