[Elecraft] First impressions of KPA1500 #113

[Larry (K8UT)]

Hi Les

I also noticed the phantom SWR indication (jump to 3.4:1 on my amp, 
displayed after transmitting - in Rx mode) that has only occurred twice, 
and those times when the temp approached 60c. The output does not seem 
to be affected - power level stays the same, and no fault condition gets 
triggered. My external SWR/Power monitors also remained unchanged, so I 
am thinking it is a display-only problem that is internal to the amp.

To try and avoid unexpected ATU retuning, studied the specs for the ATU 
memories (page 17 of the preliminary doc) and methodically spun the VFO 
across every band, pre-recording in ATU memory the settings for every 
band/segment based on its intervals (10KHz, 20KHz, 100KHz, 200KHz). 
Thereafter I just let the amp decide what it needs to do when changing 
bands/frequencies. Have not witnessed any re-turning.
