Interesting.... 

That mod is not shown in the Elecraft web pages. I did the KSYN3A updates in my 
K3 with the sub RX. How would I know if I need this mod unless someone points 
it out to me on the air? My serial number is in the 5K range. 

One of the allures of the Elecraft brand is the ability to keep current. That 
should not mean just firmware or purchase of major module updates. I'd like to 
see a mod list for the subtle hardware changes too. I may not decide to do 
them immediately but would most likely do any the next time the rig is removed 
from its desktop position. 

Same goes for other Elecraft gear like the KAT500 and KPA500. For the XG3 there 
was a recent firmware update to it. As of now I see no need for it but knowing 
it exists I would do it next time I use the XG3. 

Hopefully the powers in charge can consider a more complete mod/update 
listing. Maybe a criterion to make the list could be, "What would the factory 
do?" By that I mean which are important enough for them to do when a piece of 
equipment is returned for repair and updates.
