[Elecraft] Where do Old Synths Go?

[Dauer, Edward]

Installed two KSYN3As today; worked V73NS on 10M/CW right after so I guess
all is good.  Installation fairly easy, though one suggestion for a
revision to the instructions, noted below.

More immediate question: What¹s the best thing to do with the old boards?
As I understand it: (a) KRX3 sub receivers are now shipping with the new
synths.  (b) It doesn¹t work to have one old and one new.  (c) Therefore
anyone adding a KRX3 now has to buy an additional KSYN3A.  And (d) - I
think I saw this here a while ago - Elecraft (wisely) doesn¹t want to deal
with the old synths we-all remove.  So, those of us who have upgraded
don¹t use the old ones but someone who wants to after-install a KRX3 might
want one to avoid the additional $189.  (That¹s assuming a new KRX3 will
work with an old KSYN3 - is that the case?)  If I have all of that right,
what¹s the wise thing to do with old synths - some way to match up those
who have them with those who want them?

My suggestion about the instructions: The last step of the installation
instructions is the Initial Checks.  Calls for checking SYN1 and SYN2 on
the VFO B Display.  Fine; except SYN1 and SYN 2 don¹t appear on Display
unless Tech Mode is ³ON² in Config.  Since it is recommended that Tech Md
be normally off, I puzzled for a while about why Display wasn¹t showing
the SYNs - and then I read Fred Cady¹s book, which toggled my memory about
Tech Md.  Maybe the instructions could add that, for those who - like me -
don¹t remember everything all the time.

Also installed the P3 SVGA today.  One anomaly there; will ask for help
later if I can¹t work it out.
