[Elecraft] Problem with beta 4.18

[dalej]

I loaded beta 4.18 again direct to the K3 bypassing P3 and same problem with crackling audio.  I now reverted back to beta 4.17 and all is fine again.

I uploaded the firmware though the P3 twice, once power on P3 and the second time power off with the same results.  I will next try loading the firmware directly into the K3.  If I have the same result, I will then revert back to the previous version, beta 4.17, which worked fine including the power out.
