To friends coming to Japan with KX3,
A Japanese agent may apply JARD Technical
Standard Certification Number, however,this number is basically assigned to the
equipment with high completeness after critical check.
We know the firmware of KX-3 is currently
revised even now.

Hi all,
Ham Fair 2013 in Tokyo is held today and
tomorrow.
Elecraft equipment is not displayed at any
commercial booth so far.
We are demonstrating 6m outdoor operation
style using KX3 at the mountaineering booth.
I hope Elecraft will join the fair next
year.
Jun JI1TLL,
Dear Sir,
I have one question to complete my block diagram for the approval.
The following footnote is added to the disclosed block diagram.
L.O. output is at the operating frequency.
The L.O. VCXO Si570, however, could cover basically over 10MHz.
Some devices might be omitted between LO and
:51:03 -0700
Hi Jun,
Below VFO=2.5 MHz, we divide the synth output down much further, so
the LO is always at or above 10 MHz.
We're working on a new document that should cover all JA information
requirements.

My KX3 is blocked on 5MHz to earn an approval of JA telecommunication office.
Whenever I introduce the latest firmware into my KX3, I hope this block remains
unchanged.
Is it sure?
Jun JI1TLL,
Many thanks for OT's comment on this system.
I don't understand the process within the multiplexer chip in detail, however,
I think it's basically PSN.
In Japan, Kenwood adopted PSN in it's first SSB transmitter TX-15 about 45
years ago.
US manufactures were more advanced at that time.
It's my
Hi Wayne,
I appreciate the announcement from Elecraft.
I tried RX ISO function, and the leaked signal was disappeared or canceled

Let me know any notice other than current consumption, if you have so far and
can open.
What a deep handy!

Hi all,
I built KX3 kit (S/N830) up last week after fixing some errors.
As soon as trying some functions, I found it's really a direct
conversion system. A weak leaked signal was observed with another
receiver just on the watching frequency.
In my boyhood, I built Mizuho DC-701 which was a copy

Thanks for your quick response.

The current consumption +10mA is not ignorable in outdoor.
Thank you again for useful information.
