[Elecraft] Any solution to the audio blast issue yet ?

[Frank R. Oppedijk]

Hi Gary,

I think Enno was making his remarks here on the Elecraft reflector 
because of an earlier remark that *I* made on a Dutch K3 email list, 
and that he was referring to the audio blast that *I* encountered.

I was in a CW QSO on 20 meters at the moment the audio blast 
occurred. I probably had bandwidth set to 400 Hz, using my 400 Hz 
filter, and may very well have had the NR on, probably at setting 
F1-1. NB most probably was off. I don't recall having adjusted any 
controls just before. At the moment the audio blast happened, I was 
in QSO with DP1POL and was sending my report at that very moment.

Although the blast startled me, I did have the wits to continue 
sending my report, before pulling off my headphones and switching the 
rig off and on in order to stop the sound. AF GAIN was set to low. 
This may explain my relatively cool reaction, as I have heard from 
others here on the reflector that had only one thing left in their 
minds when the blast occurred: get them phones off my ears!

Hope this helps a bit.

73,

Frank PA4N
