Again, thank you all for taking the time to contribute to
the issue.
Ken, there was a relay of Radio China in Albania but
I don't know if it is actually active.
Ralf, this morning I measured the vfo leakage with my
second receiver a NRD-535 connected to a RS active antenna
positioned at about
Hi All,
Many thanks for all your offers, I have now received a f.b. top cover

My PR6 is for sale. $110.00 shipped USPS Priority Mail U.S. PayPal.
The reason I'm selling, I got a PR6-10.

Information on the isolation preamp is in the manual, under the PREAMP menu
item. You can choose between the 20dB preamp, the 10dB isolation preamp, and
both (30dB).
Use the 20-dB preamp when possible, since it has a better noise figure and
lower current drain. If you select 10 or 30 dB, the

I wonder why this isolation amplifier is off by default,
but assume the reason is to save battery power which
does not matter in case of use as home station.
So I would like to know if there are any degradations
in IP3 or more
This thread has moved way beyond my technical level. As I understand, the
problem arises in locations where there are very strong broadcast stations,
well outside the ham bands. Presumably a bandpass filter doesn't help --
is it that the mixing products are occurring in the antenna? Wouldn't
Hi Klaus,
My understanding is that the iso amp is identical to the 10 dB preamp but with
a reduced gain (there is a iso amp hi control signal which seems to be used
to set the overall gain of that stage). So I would expect the IP3 to settle
somewhere between the no preamp and the 10 dB preamp
I got back from my Aruba vacation Friday. It included QRPing at the
beach with the KX3 and buddipole. Info at www.ellmore.net/na1dx . It
was a blast!
One of the things I did to charge my 8xEneloop XX 2500mAh batteries
was to charge a 7Ah Battery with a small Sears 1 Ah battery charger
and then
Wayne, Thank you for this very informative technical explanation.When I
operated my HW-8 in the early 80's, I loved it because it was so simple to
build, easy to operate and required little power. However, the KX3 is so
superior I really cannot compare what you have engineered the KX3 to be

I have heard from some afflicted with this, that the situation can be helped
in a few ways.
#1- reduce the overall system gain. Turn off unneeded preamps, turn on
attenuator.
#2. Often, the interfering signal has been identified as a SW BC station
_below_ the Amateur band in use. In
By coincidence, I am also in the market for such an adapter, and found
something that should work at Jameco:

This is a 3A wall wart, so there should be enough current there to
transmit and charge at the same time if
Major thank you to Elecraft's Gary and David.I recently built a
KAT100-1 and while I caught most of my screw-up's, when I got the tuner up and
working I had a weird problem, using a 50-ohm dummyload every band looked great
with a SWR of 1.0 except 40 meters which was showing 1.2 !!! Y I
It has been noted by some that enabling the 8kHz shift means that the KX3 dual
watch feature can not be used at the same time.
Perhaps it is also worth noting that if the KX3 RX I/Q output is connected to a
PC running an SDR application such as NaP3, then the PC can be used as a second
3 amps would be more than enough to operate.
What I was thinking though was just enough to charge the batteries --
operate on batteries all day, and then plug it in back in the hotel room.
Would half an amp at 14 volts or so do? Does a little ripple (or noise)
matter if you're only charging
KX3 beta firmware rev 1.54 (with DSP rev 1.21) is now available. This revision
allows you to send CW while in SSB mode, useful whenever band conditions or
power level favor the use of CW. This is often the case on 6 meters where a QSO
might start in SSB but switch to CW quickly as fading
I just use an MFJ-1317. 13.8VDC at 2.89 amps, it's perfect for both simply
charging and transmitting from, you just need to grab a PC power cable to
connect to the other end. You can also use the MFJ-4103 (which is the same
as the 1317 but also includes a Yaesu FT-817 adaptor which I believe is
Works as expected now! This is problem is now resolved by a more serious
reseating of the KXBC3 board (as is suggested in the manual). Also, kit
builders should take care with the wire routing.
Elecraft has certainly got a jewel here. They rock! And, many thanks to
Rich, AC7, for responding.

Hi everybody,
since I own a FunVubeDonglePro+ I think my K3 is a bit deaf comparing
those 2 rigs on same antenna.
Even with switched on preamp on the K3 it's sensitivity is worse to the
FCDP+
I only heard about that the K3 is deaf on 6m but never had a comparison.
Is there a fix to make the
