[Elecraft] K3 Headset

[Tom & Barb Valosin]

Eric,

Ever since I got my K3 (used) about 9 years back I have been using a 
Heil Proset.


Connects into front mic - jack and phones. Seems to work well. I have 
been happy with it.


Tom, WB2KLD

[Elecraft] Lightning "protection"

[Tom & Barb Valosin]

Essentially, your antenna is a lightning rod. Lightning rods don't 
"attract" lightning. The dissipate the charge differential between the 
cloud and earth before the charge builds sufficiently to provide a path 
for a "leader" charge from earth to the cloud. When a "leader" is 
established, the "full charge" of a lightning strike develops. All this 
assumes a properly installed system. If you are actually utilizing a 
lightning rod system, it must be properly installed. This means solidly 
done interconnections between rods and a properly installed heavy wire 
ground. To further provide some protection, 8 foot ground rods should be 
installed about every 10 feet around the perimeter of the building. 
These rods should be bonded together. Ideally, one would use copper 
strapping about an inch in width. That is expensive. Another possibility 
is the heavy wire used by welders. The perimeter ground should be 
connected to the buildings electrical service ground. Then, there should 
be a minimum 8 foot long ground rod connected with that welding wire to 
each leg of the tower. At guy wire anchors, ground the guy, again with 8 
foot rods. Now, bond each guy-point to one another, to the tower and to 
the perimeter ground at the structure housing the shack. Yes, it is a 
lot of work. This is the type of installation used at the 55KW TV 
station at which I was engineer many moons ago. 750 foot tower. The 
safest place in a thunderstorm was in the transmitter building. The 
properly installed system provided a "cone of protection" for a distance 
of 750 feet around the base of the tower. Much of this info was provided 
by an outfit called Lincole (if I recall the company name correctly) in 
a 2 day seminar that all the station engineers had to attend. Tom, WB2KLD

[Elecraft] A thank you!

[Tom & Barb Valosin]

A thank you out to all who replied to my query about using my K3 with 
the Ameritron Amp.


I made the connections and it works. I will continue to operate at 100 
watts but it is nice to know that


there will be some power in reserve when trying to connect to 
dx-peditions and other rare ones.

[Elecraft] Anyone been successful doing this?

[Tom & Barb Valosin]

I have a K3 and recently acquired an Ameritron AL-80A from an estate. 
Has anyone been successful interconnecting these two items?


How did you do it? That is, what connections are required other that the 
K3 RF out to the amp RF input?


Reply either through this site or contact me directly at valo...@midtel.net.

Thanks, Tom, WB2KLD

Re: [Elecraft] On ground - in ground radials

[Tom & Barb Valosin]

Now in my mid seventies I have embraced the idea of conservation of 
energy. Digging in radials does not interest me. Likewise, catching them 
in lawn equipment is also a PIA. So, here is what I have done and it has 
worked well. I trim the grass.  Then I use a length of string and 
stretch it out along the path of the future radial. Next I take a 
"weed-wacker" and shorten the grass a bit more. Now I use any old 
available can of spray paint and spray a few marks along the length of 
the string. Remember to roll up the string now - no longer needed. Then 
I take my radial wire, make the connection at the antenna base and 
stretch the wire out along the marked path. Depending of the 
levelness/evenness of the surface I then take a nail and make one wrap 
of the radial around the nail, tighten the wire so it is straight with 
no loops and insert the nail into the dirt. Do this along the length of 
the radial. Typically I do it about every 10 to 15 feet. In a couple of 
days the grass grows and the wire is so low (deeply embedded) in the 
grass that mowing will not be an issue. The entire radial system need 
not be done at one time and it is easy to add radials if you wish. HINT 
- get a grandchild to help, or a neighborhood youngster or a person 
working toward their license or one of the younger club members or . 
anyone but yourself. Remember however to compensate them for their time 
and effort!

Waxing about old ham lore, a "Strays" item on page 132 of the December
1946 QST has W6KA repeating advice from W3LPY and W1MJH that
"Simonizing" 300 ohm line (or using floor wax) will "eliminate the
impedance change during rainy weather."

Paul, N6LL - current Trustee of W6KA

p.s.- That would be the impedance presented to the transmitter which
changes, not the characteristic impedance of the line.

Based on my measurements and method I used to measure 100 ft of window
line, the loss in the line from dry to wet is frankly nil. However,
the wet line does show a velocity factory change, in effect an
electrical change in line length, and thus when connected to an
antenna, will have a small effect on the impedance at the station end
of the line.

I really think and believe many comments and opinions regarding window
line, are more "old ham lore" not based on true and complete facts.

Good discussion as I was thinking to use window line in my new 630m -

Maybe revert to running parallel lines spaced 1-foot with spreaders only
at top and bottom of 40-foot 

Re: [Elecraft] Elecraft Digest, Vol 201, Issue 38

[Tom & Barb Valosin]

Condensation in shack - yes, keeping the environment at a temp not lower 
than 50 degrees F or 10 C is helpful. However - is the room insulated? 
Insulation for walls, floor and ceiling? AND - importantly, utilize a 
self cycling auto-draining (drain to exterior or covered sump) 
de-humidification. Set humidity level between 40 an 50 percent. This is 
optimum for the gear as well as human comfort and, importantly, mold 
(mould) growth opportunity is greatly minimized. Our governments, the 
military and many independent research organisations have repeatedly 
found the optimum environmental conditions for human health and 
efficiency to be 68 to 72 degrees F or about 20 to 22 degrees C and a 
relative humidity of 40 to 45 percent. Why the military research into 
this? Submariners, long distance military aircraft, sub-terranian 
control centers, space flight.


I also supply this information to my Home Inspection Clients - "Home 
Assessors" I believe our friends in the UK call them. Tom, WB2KLD

I never had a P3, but used an SDR-IQ running SpectraVue software as an
alternative.? Of course it requires a computer but if you're logging on one
already port sharing works fine.

SpectraVue "knows" the Elecraft frequency conversion and offers perfect
tracking, demodulation (if you want it and can stand the latency) and
point-n-click tuning. My K3S is now semi-retired and the main rig is a TS-890
with a built-in display which is adequate, but the SDR-IQ still has better
resolution and the other features mentioned above,? (I couldn't wait any longer
for a K4)

In 2019, I spent a fair amount of time building a LP SO2R SSB station using 2

[Elecraft] PR 6 Preamp for sale

[Tom & Barb Valosin]

When I purchased my K3 from a gentleman upgrading to the K3A he included 
a PR 6 preamp. Rich would not transfer ownership until he knew
"everything was up to date and to factory specs". (Like to deal with him 
- that is "his style"). He sent the rig and PR 6 back to the factory so 
I believe the preamp is "spot on" although I never used it due to my 6 
mtr amp having its' own  preamp.


Asking $60.00 plus $10.00 USA shipping. Contact me personally, 
valo...@midtel.net or by phone 518 827 4800 (h) or 518 231 1508 (c).

For those of you picking up legacy K3 rigs recently, you might want
to consider this option.  The PR6 was designed to help boost 10M and
6M signals as an add-on unit which plugs into the RX IN/OUT
connections on the back of the K3 with supplied BNC connectors.
There is a power connection and a control so that you can turn on the
PR6 by simply pressing the RX ANT button on the front of the K3.  Here is a 
link to the user's manual:

$60 or best offer, postpaid to lower 48.

[Elecraft] display scratches

[Tom & Barb Valosin]

Back in the "olden days" of my Ham experience, licensed 1963, on a high 
school students nearly non-existent budget, we used gentle pressure of a 
clean soft bristled tooth brush and Ipana toothpaste. Sometimes several 
applications were needed but it did work pretty well on the EICO, 
HeathKit, RadioShack and my Hammarlund HQ-180A. GENTLE-GENTLE PRESSURE.

[Elecraft] K3 stopped communicating with N3FJP log program and Elecraft Utility

[Tom & Barb Valosin]

Hello all - I am at a loss. First off - I am definitely not a computer 
X-pert, just a program user. (Not an Expert in anything - X is 
mathematical coefficient for the unknown and a spurt is a drip under 
pressure. Therefore, I am NOT an expert. Well, it was funny when the 
high school math teacher said it back in 8th grade>)


I purchased a previously loved K3, S/N 4734 from Rich, W2EG in Sept 
2016. He upgraded to the "latest and greatest" version of the K3. Before 
he would allow me to actually pay for the rig he wanted to be sure all 
was up to snuff so he sent it to factory to get a top to bottom check 
out by Keith, WE6R. Keith made some upgrades and pronounced it "meets or 
exceeds all specifications". Nice thing here - Rich did not add the cost 
into my purchase price. (If he ever says he has something for sale - 
fear not!).


The K3 worked great, communicated with rig control from the N3FJP 
logging program via Windows 10. Connected via the RS-232 connector on 
the rig. The Elecraft utility also worked well. Now (about 3 months ago) 
it started acting up. Lost a month trying to get it to work while on VK2 
holiday for a month. Now been back at it. The rig performs well with the 
exception of the communication issue. I have tried new interconnecting 
cables, run the interface to log on every combination of Com Ports, 
Rates, Parity, Start and Stop, Power, Polling rate and so forth. Because 
my son, VK2KDP is more computer savvy than I am, and the fact he has his 
station doing as it should and has helped other VKs get set up, I turned 
him loose through screen-share. No joy!


Suggestion please, or should I just pack it up to the factory?

Tom, WB2KLD / VK2RSG
