[Elecraft] K2 Question(s)

[John Parnell]

Hi - I have been playing with a newly purchased K2/100 (an older 19xx serial number with numerous "factory"mods/ updates to 2008 and 2.04P firmware, NB, and SSB). I am at a disadvantage in that I didn't build it myself and am not familiar with it "under the hood". Road testing the K2 for the 1st time in FD, I noted several items and am not sure whether to label them "quirks" or "problems"... (before posting here, I DID look at the manual,  used a search engine and browsed this list's archives)

-- When using it for the 1st time, when I pressed the mike button a few times, the power would cycle briefly; I would see the "Elecraft" logo and it would return to freq. I checked the SWR and confirmed that it was well below 2:1. I used an LDG Z100 ATU to a G5RV. I did double check the power connections from the K2 to my Astron 20 and have been running it at 95 W and less (the display goes up to 111 watts all the way C-W). I have been using the PS with no problem on my other rig, a FT-857D

- I noticed sometimes that when hitting the mic button, the display will sometimes briefly resister the HI CURRENT warning...also, sometimes, only briefly just before the ATU kicks it in tune, but sometimes it is when the SWR is close to 1:1 during the course of normal operations. I note that the CAL/CURRENT threshold is set properly to the 3.5 amp default. 

- One time, the RX audio from the speaker went dead - without me touching anything.  I tried plugging in an external speaker and it was still dead. I turned the rig off and on, and it was OK. This has happened only once

I used the radio for 3-4 hours heavily on 3 bands during FD and it worked great. The above problems did not really get in the way, but I am concerned that they might indicated a problem(s) that needs to be addressed. Any clues greatly appreciated.... you may reply direct if you wish. It is a sweet little rig. I hope it is OK
