[Elecraft] Elecraft CW Net Announcement

2018-10-13 Thread kevinr

Good Evening,

    It is spider season.  Just after the first taste of the rainy 
season and just before the mushrooms appear in mats.  Yes, spider 
season, when you can't walk more than about ten feet without getting a 
face full of web.  Every time I forget to walk with my arms in front of 
me I get coated.  They are not very big this year.  Maybe they are 
cyclical like the grouse.  The ruffed grouse is at a peak population 
level right now.  Luckily when they flush nearby they clear out some of 
those spider webs.


   The sun is hinting at a new sunspot and there are some aurora.  The 
sun is rapidly moving southward changing propagation in its own way.  I 
think the thunderstorms from the latest hurricane will be off the coast 
of North Carolina by the time the nets start tomorrow.  But who knows 
what that may have dragged into the middle of the country?  Nevertheless 
I'll work around conditions as best I can.



Please join us tomorrow on:

14050 kHz at 2200z Sunday (3 PM PDT Sunday)
  7047 kHz at z Monday (5 PM PDT Sunday)

73,
Kevin. KD5ONS

[Elecraft] Inhibit Antenna Switching on KX3 - KXPA100

2018-10-13 Thread Dauer, Edward
Way back when, I came across instructions for preventing the ANT button on a 
KX3 driving a KXPA100 from changing antennas.  It was useful then, to avoid a 
no-antenna condition in case the op forgot what was connected to what.  I would 
now like to unblock it, so that the KXPA output can be switched from the KX3 
panel, but I can no longer find that instruction.  A word search of the Manual 
produced nothing, and the Menu titles seem likewise mute on the subject.  The 
KXPA Utility allows an antenna selection but I don’t see this configuration 
option.  Anyone know how?  Tnx,

Ted, KN1CBR

[Elecraft] KPA100 kit for sale

2018-10-13 Thread Doug Shields
Hello everyone,

  I have an unopened KPA100 amplifier kit available for sale.  It is
just as received from Elecraft.  I have too many projects and too little
time to build this one as a spare for my K2 setup.  $400 shipped and insured
to US destinations.  I can accept Paypal, cash, check or money order.

Re: [Elecraft] KIO3B USB Question

2018-10-13 Thread Don Wilhelm

Rich,

The RS-232 lines in the K3 are essentially the same as the lines to the 
internal USB adapter.

That means that they are NOT two separate ports.

Yes, using the serial dongle that comes with the K3S or the KIO3B 
upgrade for the K3 does allow you to use an RS-232 port or USB adapter 
to connect to the K3, but you must move the switch on the back of the 
KIO3B in order to do that.


You would have to link the two com ports using a computer application, 
and I don't know of one that will do that.
i.e. take the COM port data from the K3 USB 'COM' port and feed it to 
the port that connects to the SDR.
As I recall, LP-bridge may have that capability, but it rather complex 
and I have not studied it.

Rich,

Not quite.  You do NOT want to connect the CBLP3Y cable to a USB to 
serial port adapter.  You will not only have communications failures, 
but you may damage the K3 USB port output and the USB to serial 
adapter because you will have two drivers on the same RS-232 signal 
lines.


I assume you have a P3 since you have the CBLP3Y cable.

You can connect a simple RD-232 Y cable to the PC port on the P3 with 
the CBLP3Y cable plugged into one side of the Y and the serial cable 
to your SDR receiver on the other side.


Your SDR receiver must turn its driver off - it can listen to the 
RS-232 traffic, but it cannot transmit requests or commands.


You may have to set up virtual ports with LP-Bridge or Com0Com.

I do something similar, but tin only a very short tip of the braid, then use
an awl to create a hole in the untinned braid near the end. Using 1/2" wide

Re: [Elecraft] Confessions of grounding

2018-10-13 Thread Bob McGraw K4TAX
Nope.  That is the same grounding scheme I've used for years. The 3rd 
pin safety ground is really all that is needed for the station inside.


As to lightning protection, that is done outside of the house and takes 
into account the tower, the rotor, the antennas and it is bonded outside 
of the house back to the AC Mains entrance ground.

[Elecraft] RFI Snapshots wanted...

Hi,

I have added an informal and unscientific survey asking if you have RFI

Please take it if you have time.  It is a single question asking if you 
have RFI.  It is two posts down on the right side.  Sorry for no direct 
link to it, it is on the sidebar.


Also, if you have any screen shots of KNOWN RFI sources, please send

For the station bonding jumpers, #10 AWG auto primary wire with a ring 
terminal attached is very adequate.   Easy to work with, inexpensive, 
does the job,  and makes for a clean installation. Personally, I crimp

I assume you have a P3 since you have the CBLP3Y cable.

You can connect a simple RD-232 Y cable to the PC port on the P3 with 
the CBLP3Y cable plugged into one side of the Y and the serial cable 
to your SDR receiver on the other side.


Your SDR receiver must turn its driver off - it can listen to the 
RS-232 traffic, but it cannot transmit requests or commands.


You may have to set up virtual ports with LP-Bridge or Com0Com.
