[Elecraft] audio problems with pro-set plus

[Scott Dunlavey]

so I used the K3 in the DX contest this past weekend... performed 
well... got great reports... easy to work in crowded conditions... I did 
notice one thing that really got to me... I am hoping I can get some 
advise on how to fix or correct my problem... from time to time, while 
using my Heil Pro-set Plus I would get this incredibly loud pop while 
changing bands or jumping to a frequency via N1MM... Not all the time, 
just once in a while... It did not happen while using the Heil Pro-20... 
just the boom headphone... any idea how to stop this...
