Re: [Elecraft] K4 Issue

[Don Wilhelm]

i have a friend who bought a K3S, and then he bought a 7300 because he 
wanted something smaller.
He said there were signals on the K3S that he could not hear and copy on 
the 7300.


So that is one users impression.

[Elecraft] OT Good Source for Stainless Fasteners and

[len]

+1 on this, though the process is "galling"  

Galling is one the most common problems when tightening fasteners. Also known 
as cold welding, galling results in damaged threads, broken fasteners, weakened 
joints and seized bolts.
What causes galling?

Essentially, galling is a form of severe adhesive wear.

Galling happens during installation to fasteners made of alloys such as 
stainless steel, aluminum and titanium. While the fastener is being tightened, 
pressure builds between the thread surfaces and breaks down the protective 
oxide coatings. Without the oxide coating, the thread’s metal high points are 
exposed to each other. This, in turn, creates friction, which causes heat that 
seizes the metal.
When galling happens

If the galling is minor, slight damage may occur to the thread surface. In that 
case, the installer may be able to remove the fastener. On the other end, 
severe cases of galling can weld the nut and bolt together and there is no way 
to remove the fastener. If the fastener is tightened once galling begins, the 
fastener may even be twisted off or see its threads stripped.

Subject: [Elecraft] OT Good Source for Stainless Fasteners and

Stainless hardware is commonly used on FM broadcast antennas.  Stainless is a 
bit on the gummy side.  When tightened, the threads tend to distort and this 
can make future disassembly a challenge.  Tower crews frequently end up 
twisting off nuts or bolt heads when replacing damaged elements.  If you are 
going to use stainless hardware, I suggest applying anti-seize lubricant, 
available at auto supply stores, to reduce seizing and galling.  I also suggest 
never reusing stainless hardware.  Replace with new.

Gary, K0CX


“When using stainless hardware there is very little strength compared to a 
steel fastener.   

So the minimum strength needs to be confirmed.  You don't want the bolts to 
shear and topple over.

Please be careful to get the right grade bolts.  You will not get what you need 
at a hardware store or a tractor supply.

This is good advice!  I had a 1/4" stainless nut gall on a stainless U-bolt

Re: [Elecraft] K3 Utility Restore config error

Thanks for the idea, unfortunately the problem persists. This makes me a 
bit more nervous than before as I have done quite a bit of upgrading 
lately (144MHz, Reflock, TCXO) and I had a fault in the tuner (capacitor 
blown), and now the refclock is off by 220Hz.


Did anybody else had the problem before and knows the fix?

Re: [Elecraft] K3 Audio Peaking Filter

[John Gibson]

Hi Bill,

Thank you for your query. My K3 has the 400 Hz CW roofing filter. Because of 
currently challenging conditions, I usually set my K3’s width control to 25 Hz. 
My preferred audio frequency is 600 Hz. 

Those were my K3’s settings when I tried to check into the Elecraft CW net last 
evening.

I engaged the APF after nothing else worked. Following N6KR’s recommendation, I 
used fine tuning (1-Hz steps). I tuned around slowly near the expected net 
frequency of 14.050 MHz and suddenly heard net control Kevin KD5ONS calling at 
14.05045 MHz. 

I recognized Kevin, as I often do, by the rhythm of his sending. He was loud! 
When I turned off the APF, he vanished.

I believe that tuning slowly in 1-Hz steps is the secret to making the APF 
work. 

I hope this helps.

73,

John, no8v

[Elecraft] K4 Initial Impressions

[Rick Tavan]

First of all, let me get this off my chest: *WOW!* The K4 is a spectacular
radio. We've all known for some time how nice it looks - the display is
gorgeous - from its appearances at hamfests. But now that I've had not only
my eyes but also my hands and ears on an *early K4D field test unit*, I can
make a few initial comments about the radio from a user perspective. Bottom
line: *It was worth the wait.*

*The box:* it's the same size as the KPA1500 amp RF deck. They'll look
great together and perform as if they were a one-box, 1500 watt radio. I
have a KPA1500 but it's at the other shack and hasn't "met" my K4 yet. I
plan to introduce them to each other later this week when I travel to the
remote QTH. It's a little heavier than the K3 but still a compact, portable
radio. The covers have nice flanges for better shielding where they contact
the front, rear, and side parts. It looks very much like the successor to
K3/K3s that it is, but the display is much more than a re-packaged and
internalized P3.

*The user interface: *It's very similar to the K3. Tap- and hold-functions
let each button and many knobs do double-duty. There are several
user-programmable function keys, four message memory buttons that can also
serve as per-band frequency memories, and most of the button functions are
the same as or similar to identically-labeled K3 functions. Some of the
controls are "soft," labeled on the display and adjustable with knobs on
the hard panel. It's a thoroughly-familiar UI for a K3 user and, I believe,
will be easier to learn for a newcomer to Elecraft radios. There will be
context-sensitive Help but I haven't used it. I was skeptical a few weeks
ago when an Elecraft developer told me that I would learn the UI in a day.
He was wrong. It took less than that.

*The panafall:* It's wider, sharper and seems even faster than the already
fast and accurate P3. The controls are "soft" rather than dedicated buttons
but have very similar functionality. You can adjust the relative heights of
the spectrum display and waterfall area. You can assign a single panafall
display to either main or sub-rx (which you couldn't do with P3). You can
also set up dual panafalls, one for each receiver. And the receivers can be
on different bands with different antennas so you can watch two bands at
once. This shack doesn't have separate feed lines, so comments on that are
theoretical based on the sophisticated antenna switching. I'll be able to
say more when I QSY to the more capable mountain QTH later in the week.

*The rest of the display:* They did a great job of providing situational
awareness here. The two receiver information areas are identical,
displaying frequency, S-meter, passband graphic, and mode info. Between
those two areas are big, bold indications of which VFO is controlling the
TX, whether SPLIT is in effect, and a smaller RIT/XIT indicator. There are
"soft" controls on the left that indicate settings for the three
multi-function knobs. You can see all the settings at a glance and control
them with zero, one, or two taps. It's an effective consolidation of what
could have been a large array of separate controls and indicators.

*The soft controls: *The eight soft buttons at the bottom invoke various
setting areas and menus that temporarily occupy space in the panafall area,
condensing the panafall temporarily to make room. The only two that require
frequent use are BAND and DISPLAY. BAND brings up band buttons with the
long-desired band-stacking register functionality. Personally, I liked the
K3 band switching model which now becomes a subset of the richer model in
the K4. The DISPLAY functionality is similar to the controls of the P3 but
more visually appealing and has the extra power described above. The MENU
area is easier to read and much more informative  than the K3 main and
config menus. Each function has a long, easily-understood description.

*Rx Audio:* At risk of overloading my use of an expletive, WOW! The
receiver audio is much improved over the K3. It sounds full and rich on
both CW and SSB, even before adjusting the touch-sensitive sliders of the
RX equalizer. (I'm just starting to experiment with that. Its functionally
is like the one in the K3 but has a nice graphic user interface.) I've
listened using a Yamaha CM500 headset and using a pair of Insignia computer
speakers, both driven through a cheap four-port headphone amp and the
speakers through a cascaded, cheap, stereo speaker amp (which shouldn't be
necessary with this receiver but I haven't pulled it out of the lash-up). I
haven't listened to the internal speaker much yet but it sounded good
during a brief test, much better than the one in the K3.

*CW:* My favorite mode. The QSK and semi-break-in are excellent. On QSK I
can hear between dits at 35+ WPM. It's clean and clear without distracting
artifacts. I'll use it often. Semi- break-in is more pleasant, letting in
less band noise. You can adjust break-in delay all the way down to "zero"
which

[Jim Borowski]

I am having depression for lack of excitment about the hobby connected with 
lost of hope and social distancing on the air waves for fear lack of sunspots 
when and if the K4 is ever delivered. Last I heard July or August.  People keep 
asking me when arrive now I tell them July or August but not sure what year 
since it is not posted for what year:-) I know one thing I have been waiting 
for over a year for it with a 5K bucks down payment interest free. On good 
thing is that 5k bucks is as n investment that did not loose value cause of the

Re: [Elecraft] OT Good Source for Stainless Fasteners and Connectors?

[David Christ]

Although we are talking about antennas, some information from the bicycle world 
is informative.  Stainless steel couplers are used to enable bicycles to be 
broken down for airline shipping. If the threads on one of these couplers were 
to gall on a multi thousand dollar bicycle, the cost to replace the coupler 
could be in the thousands.  To that end the coupler manufacturer tested over 
100 different products to see what worked best.  You can see his methodology 
and results here  and the 
recommendation here .  

I have no financial stake in this beyond owning a bicycle with stainless steel 
couplers.

[Elecraft] K3 Audio Peaking Filter

[John Gibson]

Each Sunday evening, I use my K3 #820 to try to check into Kevin’s 20m Elecraft

Re: [Elecraft] OT Good Source for Stainless Fasteners and Connectors?

[Charlie T]

Also, it's a good idea to smear some "never-seize" compound on threaded 
surfaces, especially on the larger antenna mounting hardware.
SS hardware has a tendency to "gall"  ( I think that's the correct term) which 
results from the heat generated by excess friction between the mating surfaces.
The tighter you try to make a connection, the more likely this phenomenon is to 
occur.
Once this happens, you may as well wring off the afflicted bolt and throw it 
away, cause you'll never get it off with regular tools.
The bad news is that generally, you won't notice it until you try to remove the 
hardware.  Your socket wrench will be extremely hard to turn, and when it does, 
it doesn't actually "come-loose" since the threads are effectively stripped.

[Elecraft] OT Good Source for Stainless Fasteners and

[Gary Peterson]

Stainless hardware is commonly used on FM broadcast antennas.  Stainless is a 
bit on the gummy side.  When tightened, the threads tend to distort and this 
can make future disassembly a challenge.  Tower crews frequently end up 
twisting off nuts or bolt heads when replacing damaged elements.  If you are 
going to use stainless hardware, I suggest applying anti-seize lubricant, 
available at auto supply stores, to reduce seizing and galling.  I also suggest 
never reusing stainless hardware.  Replace with new.

Gary, K0CX


“When using stainless hardware there is very little strength compared to a 
steel fastener.   

So the minimum strength needs to be confirmed.  You don't want the bolts to 
shear and topple over.

Please be careful to get the right grade bolts.  You will not get what you need 
at a hardware store or a tractor supply.

KD8NNU”
