Re: [Elecraft] KP3A circuit ?

[Erwin Witt - DK5EW]

Andy,
yes indeed I had a closer look and it seems that the left pin on P68A is by 
factory. I compared pictures of the pa board at google and there it is the same 
depend on board revision.

Re: [Elecraft] KP3A circuit ?

[Erwin Witt - DK5EW]

I have found now the circuit at the elecraft ftp server.

Found out also that there is a brocken pin at the PA board at jumper at P68A 
male connector. This brocken pin still remains in the according female 
connector. So lots of problems.

[Elecraft] Power can be set only to 12W on 100W version

[Erwin Witt - DK5EW]

Hi all,

suddenly I can set the power of my K3/100W version with the power knob on
shortwave only to max 12W and on 6m only to 8W.

That all happened when I was operating on shortwave the K3 got's suddenly
very hot. Hope that the finals did not shot.
I checked the KPA3 setting it is on "nor".

Any help on that ?

[Elecraft] HI SIG

[Erwin Witt - DK5EW]

Hi all,

last evening I switched on my K3 and got direct "HI SIG" in the display. I
dsconnected all cables but still the same. K3 is not RXing anything anymore.

Strange thing is that the morning I was operating my K3 (serial # 5776) as
normal and switched off after. 4 days before I updated firmware to latest
one but had no problem last days when operating.

Any help on that ?

Imagine having your Elecraft K3/100 for a price as low as $ 30.00? This is 
possible. You can buy my K3´s raffle for $ 30.00 a number.

 

Check the available numbers (from 00 to 99) at 

 

Then, e-mail me the number(s) you´d like to choose and I will send you a Paypal

The radio will be raffled on the first Saturday after all the numbers are sold. 

 

I will use the result generated in the official Brazilian Federal Lottery.

 

The radio will be shipped for free to anywhere in the world.

Re: [Elecraft] Amateur Radio Parity Act

[Erwin Haynes via Elecraft]

Thanks to all having brought this up!!
I already, based the ARRL President's email, sent my endorsement to my 
Senators. Geez, between working overseas, trying to keep in touch with my state 
and city issues and elections - I guess I just sent my endorsement out for the 
bill based only on ARRL recommendation. Mea Culpa!
However, our ARRL has for the most part always done smart things - from my 
view. It is not easy making everyone happy, all the time. In fact the ARRL is 
us -- just like government, we elect our reps.
Having said that -- is this a "all or none" game? Could this bill be a footstep 
into future legislation, e.g. with some/all of the the valid issues that K1VR 
brings up to be addressed?
Best Regards, ErwinN7EAH

Note that K1VR goes through this with a fine toothed comb, showing both 
its inaccuracies and exposing serious problems with the Bill itself. 
Although I have no legal training beyond the English language, I find 
K1VR's analysis compelling.

I had the very set-up you are considering building - also using the 4 position 
Alpha Delta switch. I am now converting back to a modified manual set-up.

Why? the Alpha Delta switch developed a fault -- if you open it up you will 
find that the mechanism is a thin strip of metal which is pressed to make 
contact with each respective contact of the 4 positions as you move the knob 
into the next detent.

It seems the metal strip was mounted by the manufacturer not centered, so 
that after only after a short period of usage (2 months after installing a new 
unit) the contact made to the 2 positions on one side of the switch were poor 
or even intermittent.

It cost me shipping my K-3 back to Aptos both ways and repair costs - and 
Elecraft was very nice to me on repair costs, even though this was clearly my 
fault.

So, as a matter of QTH operating philosophy, I have now purchased a MFJ coax 
patch panel, have labeled all inlets and outlets of the panel and each piece of 
coax in my QTH on both ends -- and have designed and made copies of a check 
list which I use each time I re-configure. Perhaps overboard -- but it was an 
expensive lesson learned.

FWIW.

 Group,

 This is off topic and I would deeply appreciate any responses to be
 sent to me off list.  I am posting here because I respect the
 knowledge and experience of the people who are members of this
 reflector.

 This may sound stupid but I have not had experience with this before,
 so I ask before I do something stupid.

 I use an external antenna switch mounted on the outside wall of my
 house to switch in one of six antennas and have a single coax line
 coming into the radio room.  I now have four separate radio stations,
 2 K3s and two other radios, all set up differently for different types
 and modes of operation.  All have amps in line that can be used when
 needed -- one a KW and the others 750w output.  Currently I manually
 attach the output coax for the station I want to use to the coax lead
 coming into the house from the external switch.  A pain.

 I want to be able to simply use a manual switch to select the station
 that would connect to the external antenna switch coax lead into the
 radio room.  I would then use the manual antenna switch to select the
 station and the remote controller to select the antenna.  I was
 looking at the Alpha Delta manual switch with four switched ports and
 a common and then would connect the common to the coax lead coming
 from the external antenna switch (DX Engineering) and then each output
 coax from each of four stations to the four ports on the Alpha Delta
 and then could switch stations via the Alpha Delta manual switch (all
 ports not selected go to ground) and, obviously, then select my
 antennas as I have been doing using my remote antenna switch.

 Again, this sounds stupid, but I have not had to do this before and
 always used manual antenna switches to simply select antennas.  My
 question is this:

 Given the Alpha Delta manual switch has  60dB port isolation -- is
 this isolation good enough that I can use the this manual switch to
 select stations even though each of the  stations has the capability
 delivering up to 1 KW output?  I don't want to blow out the front ends
 of the radios connected to this manual switch.

 I appreciate any answers that can be sent on to me.  I know this
 sounds stupid, but I have been a ham since 1958 and simply have not
 had or needed to do this.  I now have four great stations that I
 carefully put together as part of a plan when I retired and I don't
 want to do something stupid at this point.  I have done plenty of
 stupid things in the past and more will happen, but I thought I could
 simply ask a question here with hopes someone can allay my fears of
 using such a switching setup or educate me in those things I don't
 understand or did not think of.

 Thanks so very much and 73,
 Greg K2UM
