K3 - 10 Meters

My K3 is rather "deaf" on 10 and I was wondering how significant the KSYN3A synthesizer board would be at improving that? Is it worth the money?
Anyone have experience with that?
Thanks.
Larry, KN8N

Re: K3 - 10 Meters

Hi,
I noticed no change in RX sensitivity, but I did not test for that
either. I did however notice a very big difference in adjacent signal
interference...

See:

http://nk7z.net/wiki/elecraft-k3-macros/elecraft-k3-xlr-to-radio/elecra
ft-k3-new-synthesizer/

for some P3 graphs of the difference in both transmit, and receive...

For me the addition of the new synths was a godsend as I have a ham
living just 700 feet from me. He now has a K3 as well, and with new
synths as well...

Neither he, nor I, even know the other is active unless we get within
about 10 KHz of each other now... See the graphs to see the
difference.

What you need is the updated KXV3B.

I upgraded from the KXV3A. The B version includes 2 preamps for 12,10
and 6 meters.

I've noticed a significant improvement on 10m.

I'm not sure the new synth will improve that, but the PR6 or PR6-10
will, as will the new KXV3B with the built-in preamp.

Hi,

The new synth will not improve your sensitivity on any bands. The preamp solutions will (for 12,10,and 6m).
