Re: [Elecraft] Ham Qualifications, Customer Service

2022-06-27 Thread Dave, W8OV
Wayne,
I want to clarify what I was referring to in Wilson's email. I thought that his 
point about technology getting so far beyond the abilities and knowledge of 
most amateurs was on target, and the likelihood of being able to repair one's 
own gear diminishes with time. With the cost of labor, it does happen that 
sometimes one is better off replacing a broken unit than having it repaired, 
and a buyer ought to be prepared to do that at some point.

I have had experience with another brand that lasted a reasonable amount of 
time before something went wrong with the CW tone. The manufacturer told me to 
send it to an independent repair place he recommended. After paying shipping 
both ways plus the repair, the rig lasted a very short time before the tone 
went bad again. Shipping it, due to weight, a second time would make the repair 
cost unreasonable. Fortunately, I was prepared to buy another rig then. So the 
broken one sat on a shelf for several years, since I couldn't use it for "real 
radio", until I happened across a financially limited disabled veteran whose 
rig had just broken. As he only used phone, I gave him the rig with the caveat 
never to use it on CW. It was my second poor repair experience with that brand, 
so I understand the frustration it can cause. 

That said, my experience with Elecraft regarding repair is rather limited. My 
13 year old K3 (kit) just keeps on going. A second hand K2 I picked up several 
years ago just made it through another outdoor Field Day here in Texas where it 
worked in temperatures that reached 101°F in the shade. When I acquired it 
there was one small problem, but I got Don Wilhelm's help for that. I had a 
sensor for a W2 wattmeter fail after several years. On inquiry I was told by 
someone at Elecraft it would be less expensive to buy a new one than repair it, 
and I did. I am well-satisfied with my Elecraft gear, sympathetic to the 
problems you face with the current supply, price, and hiring situations, and 
plan to stick with and recommend Elecraft gear. But I think that on the whole, 
Wilson made some realistic observations about technology in general, and it was 
those I thought made sense. But I remain an Elecraft fan and user, and consider 
you and Eric the "good guys" in the business.

A few score years ago, I bought my first automobile with a loan. After I paid 
it off, I continued making those payments to myself. That approach allowed me 
to pay cash for every vehicle since. Likewise, I keep a "radio fund" with 
regular small savings so I'm prepared in case a repair just isn't possible or 
reasonable. Just seems practical to me. But these days that savings fund has 
become a general replacement fund because so many appliances and gadgets are 
beyond my ability or some manufacturer's willingness to repair. Instead of 
"buyer beware" it's now buyer be prepared. That's the lesson I took from 
Wilson's email.

73,
Dave, W8OV

I remember that exact same statement being made about the K3 and K3s 
(discontinued after 6 years).  Other than the new synths, it wasn't 
honored for the K3 series so I see no reason to treat that as part of 
the value proposition for the K4.

Thanks for all helpful info.
My K3 is now 10 years old and chugging along just fine.  I changed out to
the newer VFO boards and the newer I/O board.

What I am watching for is a new release of the P3SVGA which I signed up for
at Hamvention.

I am still so impressed with the K3 receiver that I never even think about
a K4.

Good wishes!

[Elecraft] K3 data mode not working on 6 meter band NQ3N

2022-06-27 Thread Robert Ward via Elecraft
Hi

 

My K3 will not display FT8 signals on 6 meters when set to
data mode. Data mode works on 10 thru 160 but not on 6 meters, FT8 decodes
fine when USB is selected.

Any suggestions would be appreciated!

   Thanks, Bob   NQ3N

Re: [Elecraft] Ham Qualifications, Customer Service

2022-06-27 Thread Hank via Elecraft
I can attest to at least one part I received as a surprise from Elecraft. I 
bought a K3S kit in 2018.  I bought a internal 2m transverter 2nd that did not 
work well. I sent the whole thing in for a checkup (K3s et al) and had the 2 
meter unit repaired and some modules installed including the higher resolution 
TXCO. The TXCO failed and they sent me a new one in 2020. It went bad. In 2021 
when things really went to crap with the supply chain they sent me an original 
TXCO for free from someone’s secret stash - just from my comments here on the 
reflector. 

I am very hopeful they will keep the K3 line serviced for quite some time if 
the rest of the world can get their act together. 

When they say K-Line I think of the B-Line twins which are still operating in 
my shack. Fingers crossed!

A few counterexamples:

- We started selling the K2 in 1999, nearly 23 years ago. We're still selling 
them. 99% of the parts are still available.

- We started selling the K3 in early 2008, nearly 15 years ago. We still 
service them (in fact repair times have gone down recently), and we're even 
building new modules in some cases to extend their life and enhance 
performance. This process was delayed by the supply chain and pandemic but 
we're getting it back on track.

- If you want to repair your own Elecraft product or ask a technical question, 
you can email Eric and me personally. Many have, and I'm sure they'll continue 
to do so. Or you can email support. 

- If you email me in a language other than English, I'll translate it with 
Google both ways. I've done this in Spanish, French, and Japanese.

- Most of the parts for our products are available from industry suppliers like 
Digikey if not directly from us. This has been true historically, and assuming 
the supply chain improves, it will continue to be true.

- I have personally supplied parts or modules to at least a dozen of our 
customers from my own lab stock over the years, typically at zero cost, zero 
shipping, just to help out when the parts were not available elsewhere.

- The K4 is designed in highly modular fashion so we can replace modules in the 
future as technology changes, including the main processor board, ADC boards, 
and DAC board. This seems preferable to, let's say, having your entire radio be 
dependent on the availability of a particular laptop computer that one designed

Yes, in the US, 0.1A1 is permitted everywhere and always has been.  One 
does often hear the term "CW sub-band" in the context of CW only 
however.  If you study 47CFR97 closely enough, you'll find that it 
doesn't even mention CW when talking about sub-band allocations, except 
for 6 and 2.  What we normally think of as the CW portion of 80 m is the 
"RTTY/Digital" sub-band.

Re: [Elecraft] Common K3 failure modes???

2022-06-27 Thread Fred Jensen
Realistically, a manufacturer can only rely on the first category -- 
readily available parts.  Production scheduling, staffing, sales, 
distribution all require a predictable, steady, stable supply of ALL 
components.  Microprocessor, microcontroller, and ASIC parts are 
especially sensitive because, to remain competitive in their markets, 
their manufacturers must keep pace with technology, and providing a 
stable supply of older, superceded parts is almost always a non-starter.


The US Air Force monitors the availability of a myriad of parts for an 
aircraft and the requirements for them.  As parts will become 
unavailable, they will often contract for a "lifetime buy" to support 
the aircraft until its retirement from the fleet, which might be decades 
in the future. This works because the USAF has the financial resources 
for the purchase and the space to warehouse all those items and the 
capability to distribute them.  A lifetime buy for K3 parts is out of 
the question for Elecraft.


My K3 is serial #642.  Elecraft has upgraded it twice, and I've 
purchased all of the modular units I will need ... plus a couple I find 
I don't need. [:=)  It is wholly unreasonable for me to expect that 
Elecraft will be able to continue upgrades in perpetuity.  I was told it 
was modular when I bought it, it turned out it was, it has met my needs 
and expectations and still does.  I've been licensed for 70 years this 
summer.  If it finally fails or fails to meet my needs, I will retire it 
and get a new one.

Re: [Elecraft] Steve KC6ZKT

2022-06-27 Thread Dynolab
And with imports aside, we have big output distortion problems with some
rigs built here in the USA.

It is scary to think what many hams would see if they ran a two-tone signal
into their SSB transceivers at full power with a supply voltage of say 11.0
Vdc?

 

Since the semi manufactures stopped making Bipolar RF Power transistors in
the middle of the last decade, most Ham HF transceiver manufactures were
forced into using inferior so-called 12 Volt MOSFETs in their finals. And as
a result, have had great difficulty in meeting even minimal Intermodulation
Distortion (IMD) standards.

Since the disappearance of Bipolar RF power transistors, many HF
transceivers from very reputable manufactures have terrible distortion
problems and if the supply voltage is allowed to drop even a volt or two,
they can end-up splattering all over the band.

Unfortunately, many hams don't have a spectrum analyzer or even the ability
to monitor a two-tone output signal so they don't know they have a problem
while the poor guy down the street is getting stepped on.

So in reality, the responsibility of a clean output signal begins at home
with the manufacture! Particularly here in the USA.

Re: [Elecraft] Field Day and FT-8

2022-06-27 Thread Ed Cole

Ham radio is a TECHNICAL hobby. We are required to pass an exam
demonstrating that we understand the underlying principles, our
privileges are based on our having that understanding, and it is our
LAWFUL responsibility to transmit clean signals.

A major problem is that many hams have never bothered to learn the many
fundamentals of radio, audio, and electronics, stopping after memorizing
only enough Q to pass the exam for their license.

73, Jim K9YC
---
Jim,

Have to smile (or cringe) at your observations.  I certainly did not 
have much technical knowledge when I got my first license in 1958 
(Novice at age 14).  And most hams were not wanting to be bothered 
explaining anything to a "kid".


I bought ARRL books and eventually QST from which I absorbed a little 
bit. I used the Q approach to passing exams (even the 2nd Class Radio 
telephone license).


My first antenna was a 40-meter folded dipole made from TV twinlead 
(locally obtainable).  I just soldered a PL-259 onto the twinlead and 
screwed into my DX-35.  Peak-n-dip and I had output.  SWR


I took Elect. Engineering in college and learned a lot of higher math 
ways of designing electronics (but the simple algebraic equations in the 
ARRL Handbook carried my further).  design now involves sw apps.


Starting as a young engineer, I learned enough to know I didn't know 
much about much.  An older mentor provided wise education on many 
things.  But with no desire or ambition to learn; null = null.


The knob thing came from many CBer upgrades to ham radio. Or "More" is 
better.  I am still running into hams that do not know how to solder 
even basic things.  My last 20-years of professional life I was doing 
surface-mount troubleshooting and repairs.  New techs just swap boards.


I use FT8 mostly on 6m.  I noted that audio level had to be adjusted if 
I switched to MSK-144 (both pgms under wsjt-x).  I run a K3.


73, Ed - KL7UW
Note to Wayne: I worked as tech writer with Hughes Aircraft for 2-1/2 
years.  But at age 78 might be a bit late for being employed, again.

Finally broke down and made 50 FT8 contacts in a little over two hours Sunday

Didn't nano-analyze the signals, but only saw a couple of obvious problem

Some shack room noise being transmitted from a hot mike.

receive them under adverse conditions?


A major problem is that many hams have never bothered to learn the many 
fundamentals of radio, audio, and electronics, stopping after memorizing 
only enough Q to pass the exam for their license.
And yet, we need numbers of those people too for public service, 
emergency communication, and general goodwill in the community.

Re: [Elecraft] KX2 on commercial airplane

2022-06-27 Thread Edward Mccann
Skip, 

I tried telling the TSA guy a little box of electronics and such was for my 
hearing aid.
He thought I was spoofing him and called his supervisor when he asked if it 
received Fox News, and I said not in my house. I explained it was the Bluetooth 
gear for broadcasting TV audio into the earpiece. A little demo for the TSA 
folks was cordial but I almost missed the flight.

One step for man, a giant step for mankind.

[Elecraft] Field Day and FT-8

2022-06-27 Thread Bob McGraw

AMEN!

I am using my K3S and P3 to observe the signals.  The antenna is a 4 ele 
yagi at 55 ft, fed with 75 ft of 1/2" Andrew hard-line.


I agree with Jim, the ham community in general has been dumed down in 
order to produce the numbers and dollars.  That's what politicians 
like.  The same thing is happening in our schools and colleges in order 
to get desired passing numbers.

Which bands have a CW segment?  Did I miss a band plan change?

Re: [Elecraft] KX2 on commercial airplane

2022-06-27 Thread Skip Davis via Elecraft
Bill I haven’t had any problems with having my KX2 in my carry on bag, even 
with mic and headset along with other interconnecting wires. On my last trip I 
got flagged because of all the gear. While explaining to the TSA agent about 
ham radio I actually powered up the KX2 and showed him how it worked, he 
thought it was pretty neat. 
By the way it wasn’t the KX2 they wanted to checkout it was something else.
