Hi Steve,

See:

for some actual test data, with plots of new vs. old synths... You will need to decide if you are happy with your purchase.

Now that I have installed the recently received KSYN3A upgrade in my K3, I
am wondering what improvements to expect? I have seen test data on this
list showing improved transmit performance and anecdotal reports on
improved receive performance. In an initial quick listening session on cw
and FT8, I don't hear any dramatic changes in receive performance.

The KSYN3A upgrade is a significant investment (over $400 when including
shipping and tax) and will likely increase the resale value of the radio
somewhat, but as a casual operator should I expect to experience any
noticeable performance improvements?

After just about two years from my original order, I finally received the
upgraded K3 synthesis board (KSYN3AUPGD). Installation will take place this
weekend and I'm hoping for the best.

It has been over 8 weeks since Eric announced that most of the long
delayed K3 options would be available in 6 to 8 weeks, and "should ship
close to these dates ranges if there are no new
parts issues or surprise manufacturing delays."

I have been patiently waiting for the upgraded synthesizer for my K3 and
made a 50% payment two years ago.

Any update on this? It would be nice to have some info on whether these
upgrades are being delayed once again or about to ship as promised.
