[Elecraft] [K3] factory upgrade to K3(s)

[Mark E. Musick]

Ronnie and Don,
There is no need to pop the cover to check the K3 to see if it has the new synthesizer. It says on the Elecraft website they started installing the new synthesizer in the K3 starting with serial number 8801. If your K3 serial number is 8801 or higher, you have the new synthesizer.

Ronnie,

The latest K3 builds included the new synthesizers.  Open the top cover and look - if your synthesizer board(s) have a 3.5mm jack at the top, they are the new ones.
The new synthesizers make a big improvement - If I recall it is an 8 to
10 dB improvement in the receive noise floor.  I am going from my recollection of Eric's presentation to FDIM just as the K3S was being announced.
