[Elecraft] K3 Future Factory Hardware Updates; + New beta f/w release 3.27

[Larry - K2GN]

I just ordered the K3 VFO TUNING NOISE REDUCTION and I'll do the
AUTOMATIC FRONT END PROTECTION  (1 wire mod)
when I get into the radio.
I can't find anything on the 3rd mod mentioned in Eric's announcement on 
August 25th,
 IF OUTPUT BUFFER GAIN MOD (For the P3, LP-PAN etc).
Is there a modification sheet for it somewhere on the site?
I will be ordering a P3 down the line and I may as well do other mod now.

Thank you,
de K2GN/Larry
