[Elecraft] K3 SWR

[Jay Krishna]

Just completed assembling my new K3/100; I am completely new to this rig, and just getting used to it. In initial transmitter power calibration into a dummy load, I saw an SWR of ~1:1. However, into my 20M mono-band dipole, I see it is ~1.8:1. I am wondering if anybody can help answer these questions:
 
1. Is it safe to operate the K3 with an SWR as high as 1.8:1 (just eager to test the new K3 on the air)?
2. Do I need to check if there is a problem with my dipole antenna (wet coax, etc.)?
 
Thanks,
