Since it is so easy to switch out the outboard preamp, we have frequently
done this on some of the weak sigs just to see if we could still hear them.
In many cases we could hear them Q5 with just the internal preamp. Ian,
I have just finished putting together, and testing a 6m preamp kit
from Down East Microwave. As I use the RX Ant input on the lower
bands, and not wanting to put in a relay, I have made up a
Diplexer to separate out the 2 signal paths.
Although the arrangement is a bit of a lash up it has proved
Ian,
One also needs perhaps 10db of noise headroom for modes like JT65
which copy many db below the noise.
My opinion is the an internal option for this preamp is needed.
Dangling still another box with the attendent extra cables outside the
K3 isn't desirable here. Yes the preamp does
I would hang on to your XV-50 until you have checked that you find
your K3 sensitive enough on 6m. I made the mistake of selling mine
off before my K3 arrived, and I now regret it.

Well, let's see now, is the K3 sensitive enuff for serious weak sig work on
six.
Based on our first week here on Sable, doing mostly weak signal work, I
could not be more pleased.
We were fortunate to have been given one of the prototype preamps to use
ahead of

I'm running a 7/7 stack, at 160'/140'. Separately, I have a Hy-Gain
66DX fixed NNE at 90'.
Switching beteen either of the above antennas and no antenna, I
generally hear no increase in background noise level on my K3. Not a
good sign. When I had an ICOM IC-756ProII, and, before that,
Thanks Dick for the new one on 6. You guys are doing a great job.

Can you give a little info on the protoype preamp? external? how is it
powered? pics?
ok ok, you can answer all that when 6 dies down ;)
Thanks!

Fellow Elecraftorians:
Some weeks back I recall a post here that the K3 6-meter performance did not
seem to be up to par with its HF band performance as well as that of some of
the other HF thru 6 rigs on the market, and there was some related
discussion regarding a future accessory receive
Terry,
In the event you missed my previous post ...
I live in a quiet rural setting and when I connect my 6M
1/4 wave GP my noise rises. That tells me ... at least at
my location ... that more gain / better receive would be
of little help.
