[Elecraft] New Synthesizer boards

[Jim's Desktop]

Got my new KSYN3A boards in this morning.  Installation took about 30 
minutes and it was not necessary to remove anything but the old 
synthesizer boards and install the new ones.  I'll echo the sentiments 
of not having to re-install those lockwashers on the back of the boards!

Everything fired right up and it's a little too soon to tell for sure, 
but I had been having a lot of internally generated noise on 6 meter 
receive and that's gone now.  Also gone are the Key Clicks that were 
plaguing me on 6 meters when the KPA500 was on.  Contributing to the 
demise of the 6 meter clicks may also be the installation of a brand new 
Cushcraft 5 element Yagi in place of the 3 element one that had been on 
the tower, but I did test for clicks after I installed the beam and I 
could hear them using my KX3 as a receiver.   They seemed to disappear 
when the amplifier was in standby.

With the new syn boards, I can no longer hear any clicks on 6 with the 
amplifier running and the amp will run right up to 550-600 watts out 
without them showing up again.  All in all, I'm extremely happy with the 
new synthesizers and I'm also able to hear several non-directional 
airport beacons from close by airports within 50 miles of my location 
using my 160/80/40 trapped dipole so having even limited VLF capability 
is a big plus here.  I'll try it again late this evening after the D 
layer absorption dies down and see if I can hear some of the other 
beacons that are still active throughout the state.


Anyone need a couple of "old style" synthesizer boards?  They can be had 
real cheap - LOL.
