Re: [Elecraft] KX3 out of band TX inhibit

[Don Wilhelm]

Oliver,

Did you buy a used KX3?  The prior owner may have requested and 
installed the MARS software which opens up transmit to non-ham band 
frequencies.
Contact supp...@elecraft.com to find out how to restore normal US band 
limits.

Re: [Elecraft] KX3 out of band TX inhibit

[orbarrett]

Should clarify that my KX3 application is for an unusual transverter setup
that uses direct CW transverter keying that doesn’t involve the KX3, which
is just used as a receiver.  I just wanted additional insurance against any
TX power getting into the transverter RX output as result of hitting the KX3
XMIT button by mistake (my other transverters that I’m accustomed to are
bidirectional and do use the KX3 XMIT button).

Hi Oliver,

Probably the best protection for you is your knowledge of the Part 97 rules

Re: [Elecraft] K3 Sticky Power Control

[Grant Youngman]

So it’s probably not the rotary encoder.  My first guess is that it could be 
related to oxidation on the front panel pins where they plug into the main 
board.  Or pwr cal maybe? — not sure if that could cause these symptoms.

Others here (likely smarter and better looking) may have a better idea ..

Hi, Grant.

Great suggestion.  MON and CMP functions work fine.  The PWR behavior is
that sometimes the power level indicated on the display will not move (or
move a few watts) no matter how much I turn the knob.  Other times it may
move down 10w or so and then won't go lower.  

It seems to be intermittent.  I don't need to adjust the PWR often: only
when I'm running QRP with it instead of the K2.  Setting up Macro for that
is probably the easiest solution.

[Elecraft] K3 Sticky Power Control

[engineercm]

I have an older K3 that is up to date with firmware and is acting odd when I
try to change the power out using the PWR control on the front panel. I can
change power fine using a macro but wonder why the control acts so strange.

Please forgive me for the bandwidth if this has been discussed before, but
all the search permutations I tried using PWR, Control, Sticky, Problem
turned up nothing.

Re: [Elecraft] Re KX3 booster

[Bill Frantz]

Or why may US companies that manufacture in foreign countries 
have decided they need to have full-time staff from the US in 
the foreign country to monitor what's coming off the production 
line. Many of these foreign manufacturers are always looking for 
ways to cut costs, and those RFI suppression components really 
don't do anything useful, particularly in the RF environment at 
the factory.

Do they even still sell Plasma TV's?

I sprung for a regular LED illuminated, LCD screen LG 47 inch with 3D, which 
turned out to be a total bomb, about 5 years ago and have never heard a peep of 
RFI from it.

I DO watch "John * Carter"  in 3D every so often, but it's the ONLY movie I 
have in 3D.
(The LG method is the same as used in movie theaters, with totally passive 3D

Plasma TV sets are often big RFI generators.  And, they have the annoying habit 
of developing burn-in... much like CRTs if a constant image is displayed.  I 
used to work for a TV network that used plasma displays as part of studio set 
decorations, and they quickly discovered that using a plasma display for an 
identifying graphic (a logo or some such) resulted in major burn-in, in part 
because they pushed the brightness of the display, so that it could be picked 
up by studio cameras in a brightly lit set.


RFI was not a big concern at the TV studio, but there have been many stories of 
neighbors who purchased a plasma TV set that happened to ruin their radio 
reception... as well as the HF activity of nearby amateurs.

Jim,

Ditch the Plasmas and be sure they leave your neighborhood.

I've got one of those insanely oversize LG OLED TVs and it puts out zero RFI 
that I can see on the P3. I did a lot of testing during the free return period 
just to be sure I wasn't bringing a noise generator into the house, and it's 
excellent in all ways. Also, it uses so little power compared to a much smaller 
Vizio TV, The glass is cool to the touch and the processor compartment is 
slightly warm at most.

OLED can produce a lot of brightness and power consumption relates to 
brightness so how you set it up matters energy-wise, but your Plasmas are 
multiples of the power the OLED uses. One very nice thing with OLED is you see 
genuine black, no backlit shade of gray, it takes awhile to get used to seeing 
very accurate color and shading when watching in a darkened room, we don't see 
that with the other kinds of TV.

Did you use set CONFIG:TX INH to Lo=Inhibit?  What are you connecting to K3
ACC pin 7 to inhibit transmission?  Did you supply 5V to that pin through a
current limiting resistor or did you get it from Pin 1?

For a safe sample SO2R TX inhibit circuit, see https://bit.ly/K3lockout .

But perhaps all you should do is increase CONFIG:TX DLY or your PTT IN

[Elecraft] K3S TNX INHIBIT & WSJT-X

[John Stengrevics]

To provide enough time for relays protecting a preamp to switch, I have enabled 
TNX INHIBIT on the K3S.

Does anyone know if operating WSJT-X disables TNX INHIBIT or effects it in any 
way?

Re: [Elecraft] OT: TV RFI Question

[Raymond Sills]

Plasma TV sets are often big RFI generators.  And, they have the annoying habit 
of developing burn-in... much like CRTs if a constant image is displayed.  I 
used to work for a TV network that used plasma displays as part of studio set 
decorations, and they quickly discovered that using a plasma display for an 
identifying graphic (a logo or some such) resulted in major burn-in, in part 
because they pushed the brightness of the display, so that it could be picked 
up by studio cameras in a brightly lit set.


RFI was not a big concern at the TV studio, but there have been many stories of 
neighbors who purchased a plasma TV set that happened to ruin their radio 
reception... as well as the HF activity of nearby amateurs.

Jim,

Ditch the Plasmas and be sure they leave 
your neighborhood.

I've got one of those insanely oversize LG 
OLED TVs and it puts out zero RFI that I 
can see on the P3. I did a lot of testing 
during the free return period just to be 
sure I wasn't bringing a noise generator 
into the house, and it's excellent in all 
ways. Also, it uses so little power 
compared to a much smaller Vizio TV, The 
glass is cool to the touch and the 
processor compartment is slightly warm at 
most.

OLED can produce a lot of brightness and 
power consumption relates to brightness so 
how you set it up matters energy-wise, but 
your Plasmas are multiples of the power 
the OLED uses. One very nice thing with 
OLED is you see genuine black, no backlit 
shade of gray, it takes awhile to get used 
to seeing very accurate color and shading 
when watching in a darkened room, we don't 
see that with the other kinds of TV.

Re: [Elecraft] [K2] External Fan Hum

[Fred Jensen]

I tried an AC muffin fan on my KPA100 ... while it worked wonders 
keeping the heat sink cool when I was using the K2 for RTTY, it induced 
hum.  I switched to a brushless DC fan from an old computer and it 
solved the problem.  I can't tell you if the K2VCOSHLDKIT would work or 
not since I opted for another solution.  The DC fan was inaudible 
acoustically.  I fastened it down with a little tab of velcro, blowing 
down onto the heat sink.

Re: [Elecraft] Elecraft Order Status Page - AX1

[Eric Swartz - WA6HHQ, Elecraft]

The link to the shipping status page is near the right side of the top header of 
most of our pages at elecraft.com

Does anyone know where the Elecraft Order Status page went?

There was a version dated September 5th that stated AX1 orders were 
overwhelming, but I can't seem to find that anymore nor can I get an email 
response.


Just curious about timing of AX1 order deliveries; not concerned about Elecraft.

Re: [Elecraft] [K2] External Fan Hum

[Don Wilhelm]

Steve,

Yes, an AC fan would induce alternating magnetic fields in the K2 L30 
and T5 VFO inductors.  The K2VCOSHLDKT will eliminate it, as will a DC fan.
The DC fan may have a magnetic field, but it would be constant instead 
of alternating polarity 120 times a second.

[Elecraft] KPA500 hum; horrendous

[ANDY DURBIN]

Hum level depends on PA current draw from the torroidal transformer.  What is 
your PA voltage key down?  What is the complex impedance of the antenna system 
as measured at the amplifier?


I reduced my KPA500 hum level from intolerable to acceptable by adjusting the 
transformer voltage tap and bringing the antenna system load close to 50 ohm 
resistive.

Re: [Elecraft] [K2] External Fan Hum

[eru...@att.net]

Steve,When I had my KPA100 I had a small I think 4" diameter 12v dc fan to 
which I added some small rubber feet and placed it flat on top of the heatsink. 
 I never had any hum issues.

Re: [Elecraft] Re KX3 booster

[Bob McGraw K4TAX]

My comment and understanding on "FCC Certified".    The FCC now allows 
companies to perform "self certification".   In other words, they allow 
the fox to watch the hen house.    The companies can elect to do the 
testing and submit the results to the FCC. Thus the FCC does not 
actually test products to issue the certification.   I personally find 
many items, such as, power supplies, CFL lamps, routers, printer power 
supplies, and a host of other items that are producing noise and these 
do have the required Part 15 along with other certification labels.


I did work for a company whose products were required to be "certified" 
by several safety organizations and to meet radiation and safety 
standards.  We used an independent testing company for all of these 
tests.     On more than one occasion I observed a product just barely 
meet or just barely  exceed the required radiation levels.   The company 
said "this is close enough we can pass it".   I said NOPE, it has to go 
back to Engineering to be improved.  Well need less to say that caused 
turmoil with Sales, Marketing, Engineering and Management.    But I 
stood my ground and said "improve it" knowing that production units 
might be worse in terms of emissions.   Many companies seem to take the 
approach "we saw it work once and it almost meets specsship it". 
Further we find that production changes through the life of a product 
may be related to part and design changes.   No further testing is 
required as the model number does not change.   The labels are affixed 
and the items shipped.  Who knows if they meet the required safety and 
emissions requirements?   Just because it has the required labels and 
statements is no assurance that it meets those requirements.   It is 
called "economics".

John and All,

I’m not necessarily recommending these amps, but you may possibly be confusing 
them with a prior model line--  The original  “HLA” series, such as the HLA 150 
and HLA 300.  Those amps were marginal at best, although if you ran them well 
below their rated output they weren’t “too dirty”!  Hi.  RM Italy also sold a 
line of amps that didn’t even have proper bandpass filtering as they were 
intended primarily for CB.  I think those just had an “HL” designation.

These newer models supposedly are a much better design.  I first saw them at 
Dayton a couple of years ago.  The price went up substantially too!  Supposedly 
these are all FCC certified, whereas the prior models were not.

Re: [Elecraft] KPA500 hum; horrendous

[Macy monkeys]

I suspect that may be the case, Bob. I will wait until I hear from tech support 
before I pop  open then amplifier for a look-see. It is factory built.

Regarding power output, I was incorrect. On 80 and 40 meters I am seeing 
similar outputs as you. I am on a 240 source, HV is 74 volts.

Re: [Elecraft] KPA500 hum; horrendous

[Bob McGraw K4TAX]

Zero hum from mine.  From other comments, be sure the power transformer 
is correctly installed and secured.  It may have moved during 
transportation if you purchased a factory built unit.


As to 20 watts drive and 350 watts out, what bands?    With 20 watts 
drive from my K3S I see 450 to 550 watts out on all bands as seen on the 
amp LED indication and on an external {Bird 43} meter.    The HV is 62 
volts and the current is 11.5 amps into a dummy load.  Amp is operated 
from a 240 source.
