[Elecraft] K3s/0 and RRC's in ARRL DX SSB Contest

['DGB']

Wondering if anyone used the above in the contest with N1MM+ and 
experienced delays after the macro .wav played out? They were long 
enough to where I only heard the very end of my call when a station came 
back to me. I used Audacity to cut the tails off. prior to this.

Also wondered if there was a way to record a wav file directly in MM+ as 
sitting I could sitting in front the K3? The Cntrl Shift F-key routine 
didn't work.

As a side note, also not able to record to the M1-M4 message keys on the 
K3s/0 in cw either as on the K3.
