[Elecraft] K2 and installing KSB2 & 160m

[Doug Hensley]

Sorry for the bad subject line on my first message.  I was going to ask about the UNPCBSthings and then decided not to.  Here's my original question:

I have a used K2 (2007 build) with KDSP2, KAT2, KNB2 and internal gel cell battery.
I have ordered the KSB2 SSB option as well as the 160m band/aux receive option.
If anyone remembers putting these options in, were there any lessons learned and so any recommendations you might be able to pass on to someone installing thesefor the first time ?
Thanks for any comments,
Doug
