Although this says designed for the KX3, I assume there is no reason why this
can be used as a source for anything, including to calibrate the K3?

Every man is a damned fool for at least five minutes every day. Wisdom consists
in not exceeding the limit.
This may not always be the same, Jim. My first XV144 transverter had
steel top and bottom covers, but in later XV--- transverters they were
made of aluminium. The type of material used could have something to do
with availability, cost, weight or strength. Unless Elecraft state
otherwise, it may
Hi Jim,
As a point of curiosity here's a posting from Wayne (04/15/2010) describing
the reason for using steel in the P3 enclosure:
/The P3 enclosure is being fabricated entirely from corrosion-resistant
steel (plated before painting) rather than aluminum. Production and
field test units
I am building my 3rd Elecraft K series kit, this time a K2, my second.
All has gone well. I am on page 80 of the manual, right column, 3rd step,
adjust C21 and C23 for maximum power output. Adjusting C21 does
absolutely nothing. Regardless of a very slow 360 degree rotation, power
out does
I fully agree that PCB diagrams would be a great assist when
troubleshooting and modifying the K3 and its associated bits, pieces,
and equipment. When I worked the tech repair bench at a ham radio store,
I would have been quite crippled without PCB diagrams.
Comments from Elecraft on the
Wiley,
I trust you are peaking the bandpass filters at the 1.5 to 2 watt level
rather than at 12 watts. If you are trying at 12 watts, you may not see
the peak because the power is already near the maximum.
Check the values of C19, C20, C28 and C22. If those are all correct and

I have home-brewed a number of enclosures. for one of the reasons Wayne cited--
enough weight to keep the piece of equipment stable on the desktop -- I have
settled on brass as my favorite metal. Depending upon the nature of the
project, I sometimes also use copper.

I have the same problem. KPA500 (sn0856) on/off normal for 9 months,

would be interested in seeing the cure. Interconnect cables are home built

Just a follow up, I talked to Howard at Elecraft a short while ago (Elecraft

Any advantage to using 220V vs 110V to power the KPA500?
Absolutely. Less current through the wires, lower current in the xfmr, lower
impedance power source, etc. If it is available, use the 230 line.

Hi All,

connected properly, the K2 set to Hand for the input device, and the the cables I made
are properly
This is perhaps rather a special case and may have been addressed
elsewhere but others may be interested. I developed an interface and
setup for the K3 to use N1MM and MMTTY for both FSK (not AFSK) and CW

and back with no
Your interface can also be used with PTT control in CW by simply
setting the Digital port RTS to PTT. In addition, the three

and MMTTY's EXTFSK driver.
The interface is essentially the same as documented by AA5AU on
his RTTY
David,
Do you have the plug from the CMOS4 wired correctly?
There are only 2 lines to connect. The hot line should go to the tip
and the ground line from the CMOS4 should connect to the shell. No

You MUST use a stereo plug in the K2 key jack. A mono plug will short the 'ring'
connection to ground, which will key the rig. In HAND mode, either tip or ring will key
the K2 when grounded.
