[Elecraft] K2 and the UN-MODULE things

[Doug Hensley]

Hello,
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
