[Elecraft] K3: Low RF output only on 30 meters

2016-01-24 Thread Scott Manthe

Hello to the list!

I fired up my K3 tonight for the first time in months to try to work K5P 
and the VP8 expeditions. Thing seemed to be working fine until I tried 
working the VP8 on 30 meters. I noticed while sending that I didn't have 
much output on 30 meters. Investigating, I get output until I hit the 
threshold when the KPA100 kicks in. Full output until I got past 12 
watts and them little or no output past that point. I seem to be getting 
full output on the other bands. Any guesses? It's vexing...

Snap-on beads are NOT effective on the HF bands.

[Elecraft] Filtering RFI from LED & flouresence Dimmer Switches

2016-01-24 Thread johnpierce
I have several dimmers around my house that generate 20db of noise on the HF
bands.  I have seen some recommendations for ferrite beads that can be used
for filtering.  However, I cannot find that info.  Some were snap on beads.
I am assuming that locating them in the power feed lines to the dimmer box

I would think that just a simple blue ESD mat, and a wrist strap, on
your favorite workbench is more than sufficient for any home based hobby
operation.  If you really wanted to be thorough about it a warm mist
humidifier going in the room your workbench is in would be a helpful and
inexpensive addition.  Just be sure your blue mat is solidly connected

Seems to massive overkill if you're only casually needing ESD once in a while. 
If you're going to go all the way then you need a temp/humidity controlled

Re: [Elecraft] : Soldering station recommendation in preparation forbuilding a K1

2016-01-24 Thread David Anderson
I got one of these hot air rework stations with a digital temperature 
controlled iron on eBay in the UK. Takes regular Hakko soldering iron tips.  It 
is model 862D+ and is well made, and excellent value for money.  I already had 
another analog temperature controlled iron but prefer this one now.  I imagine 
there must be equivalents available over there designed for USA voltages.

http://www.ebay.co.uk/itm/Soldering-Iron-Desoldering-Unsoldering-Station-Hot-Air-Rework-Gun-Display-/181456682143

I also have a very old Weller temperature controlled iron, but as it uses the 
magnastat type of tips it isn't ESD safe as the tip doesn't have a solid earth 
connection. Saying that I have built things like 10 GHz GaAsFET preamps etc 
with this old iron (when I didn't know any better) with no damage.

Re: [Elecraft] [KX3] Easily Swap From Voice to Data

2016-01-24 Thread David Anderson
Hi Joe,

I had the same requirement, as I frequently switch between SSB and WSJT modes 
with my KX3. 

It is unfortunate that the KX3 has no separate Data audio input port and 
plugging unplugging the Microphone every time is very tedious.

So, I had to build my own data/ mic switch box, which gives me a choice of 
either a desk or fist microphone, a headset microphone with foot switch PTT, or 
data from sound interface. It also means that when my "data" switch is in the 
"mic" position the computer has no way of enabling the PTT by mistake when the 
computer is starting up and it "ackles" the com ports. 

It was but an afternoon's work to make this simple box with a couple of 
switches, and some jack sockets.

Re: [Elecraft] : Soldering station recommendation in preparation forbuilding a K1

2016-01-24 Thread Brendon Whateley
Hi Edward,

Do you do much SMD work? If so, what do you use for that? I'm thinking of
getting a hot air rework station to make life easier with SMD, which seems
to be the future.

[Elecraft] Pricing a K2.

2016-01-24 Thread Dudley Chapman

Forgive me if this is not appropriate for this forum.   I have a K2 that I 
bought and built quite a while ago.  The serial number is 2522.  I used a few 
times but then had to put a lot of time into a company I started about that 
time.  It looks brand new inside and out.

I recently bought all the mods to bring it up to date, but decided that my 
interests are more in the line 
of SDR, so I did not install any of them yet.   The details are:

K2 serial number 2522
Built in autotuner.
No SSB module.
All the mods from Elecraft, not installed.

I was wondering what would be a fair asking price and where I should post it?  
Thanks in advance.

Dudley Chapman, WA1X

[Elecraft] Feature Request for P3

2016-01-24 Thread David Cole
Hello Elecraft,

Would it be possible for Elecraft to add the following feature to the
P3:

Allow P3 macros to be stored and triggered via the USB keyboard port on
the rear of the P3, as is currently being implemented now for the K3
macros.

In essence, I want the P3 to let me fire a P3 macro trigger, (in
addition to a K3 macro triggers), in the same way I now fire K3 macros--
using the USB port on the rear of the P3.

Thanks!

[Elecraft] Soldering station recommendation in preparation for building a K1

2016-01-24 Thread Reuben Popp
I built my K2 with an old Weller TC-202 I have here; it's my "go to" iron
for most of my projects. That iron was "gifted" to me after serving hard
time at the local community college.  It's not super pretty, but it still
works and well at that.  You would be hard pressed to find a better deal
IMO.  One can generally pick them up on eBay for ~45 or more in working
condition.  Great iron, and as with most things Weller, one can still
always find parts out there.

it gets rid of low frequency components of voice that make no

Re: [Elecraft] Elecraft] KX3; Procedure for Setting TX CMP & TX EQ + DVR

As TX EQ could effect overall audio amplitude peaks, it would seem

That's exactly right. Most mics should have TXEQ set for maximum cut of 
the three lower bands, with 6 dB cut of the fourth band, everything else 
set "flat" -- that is, no boost or cut. A few mics benefit from a few dB 
of boost in the higher two bands.


Once TXEQ is set, then set MicGain per the manual, then adjust CMP so 
that you see no more than 10 dB of compression on peaks of TX audio.


This will optimize audio for best communications quality, and for 
performance under weak signal conditions, boosting your "talk power" by 
nearly 13 dB. The recommended low-cut is typically good for 2-3 dB -- 
that's how much power is wasted by low frequency components of voice, 
which make no contribution to intelligibility.

[Elecraft] Elecraft] KX3; Procedure for Setting TX CMP & TX EQ + DVR

2016-01-24 Thread jkiracofe51


I desire to utilize both CMP and TX EQ in SSB transmissions on a KX3.


In the KX3 Owners  Manual, there are well defined procedures for
setting Mic Gain, CMP and TX EQ, but it leaves doubt as to which to
set first as Mic Gain and CMP are grouped together with TX EQ
described several pages later. This would imply TX EQ would be set
last. 

As TX EQ could effect overall audio amplitude peaks, it would seem
that TX EQ should be set first then adjust Mic Gain for proper levels,
then set CMP. 

What is the Elecraft recommended procedure / order  for setting these
three adjustments ? 

My next questions involves storing and playing messages on the DVR
where CMP and TX EQ are desired. 

With Mic Gain, CMP and TX EQ set as desired for a CQ message for
example, would the DVR store the message as processed with CMP and TX
EQ active ? 

Assume I leave the Mic Gain, CMP and TX EQ at the same setting when
the DVR  CQ message was stored …  When playing the message back on
the air, would the message be processed twice (CMP & TX EQ), once
during recording and once during playback or just once ? 

Feedback will be greatly appreciated.

  and B VFOs are on opposite sides of the display. To use, tune
  in the DX on A and put B just above the pileup. Press the
  button.

  P3 for band scanning: Band edge aware setup for fixed spans,
  e.g. 50KHz, 100KHz 200KHz. Read VFO A. Set span to the fixed

Re: [Elecraft] Fwd: OT Mystery QRM Help (Video)

2016-01-24 Thread Bob McGraw K4TAX
Usually electrical noise is very broad band in nature.  I use the MFJ 
unit to find the general direction, triangulate to an area, and then 
using a 24" reflector type microphone, equipped with a high gain audio 
amp and headphones, go "listening to poles".  {Yea the neighbors think 
I'm crazy, but so what.}  You can actually hear the arcing at connectors 
for conductors, ground arcing or insulators arcing.   I've even stood on 
the ground with the crew from the power company and identified the exact 
connector which is loose.  Another handy item is an infrared 
thermometer.  A hot spot is likely a problem spot.  This works to scan 
ones breaker panel as well.


If the noise is inside a building or house, proceed with caution. Dogs 
bite and occupants may shoot first.


If the noise is from a device oscillating this is more frequency 
selective and a bit more of a challenge to find and isolate.

Hello group mind,

I have a P3 control question for you all...

It appears to me, that the P3 does not accept macros for itself, via the
trigger launch process which fires off macros to the K3.

Is this assumption on my part correct?

If so, is there a way to trigger the P3 to accept a macro designed for
the P3 itself, using the rear USB connector on the P3?

In essence, I want to be able to control the P3 via it's own macro set
using the USB connector in the rear of the P3 itself.  Is this possible?

[Elecraft] P3 Macro question

2016-01-24 Thread David Cole
Hello group mind,

I have a P3 control question for you all...

It appears to me, that the P3 does not accept macros for itself, via the
trigger launch process which fires off macros to the K3.

Is this assumption on my part correct?

If so, is there a way to trigger the P3 to accept a macro designed for
the P3 itself, using the rear USB connector on the P3?

In essence, I want to be able to control the P3 via it's own macro set
using the USB connector in the rear of the P3 itself.  Is this possible?

Re: [Elecraft] P3 Fixed/Tracking Toggle Broken

2016-01-24 Thread Cady, Fred
Hi Ken,
I don't know if you have solved this yet but it sounds like the rs232 link 
between the K3(S) and the P3 is not there.  The P3 defaults to Tracking (Fixed 
VFO - Tuned Spectrum) mode in that case.  If you are using the KIO3B, make sure 
the RJ45 is plugged in securely with a definite snap when it is.
Cheers,
Fred KE7x

I switched my K3 to split to see the VP8STI pile-up. Now I am stuck in
tracking mode. I go into menu/FixTrack and when I click to toggle, nothing
happens, even after exiting split mode. I've turned the K3/P3 off to no

[Elecraft] : Soldering station recommendation in preparation forbuilding a K1

2016-01-24 Thread Edward R Cole
I have the genuine HAKKO FX-951 (ESD safe) solder station which is 
essential for good soldering.  It does cost double the other guys but 
the "sleep" mode is very nice as tip temp is dropped to 450F when 
solder iron is parked in its holder.  It returns to 670F (temp fully 
adjustable) a few seconds after I take the iron out of the 
holder.  This feature really extends life of the tips.  Having a 
professional station really makes my little business of building kits 
much better/easier.

Re: [Elecraft] Buying K2 or KX3

2016-01-24 Thread Phil Wheeler
I agree with Ted. Building my K2 from 1999-2003 
(as new options like SSB and 100 W came 
available), with various updates and mods into 
2014, was one of the best experiences I've had in 
ham radio. With the dominance of SMT in today's 
designs, the K2 may have been the last major kit 
of that type, alas.


But if Jim is buying a rig for QRP ops vs. the 
building experience, the KX3 wins by a pretty wide 
margin IMO.

Re: [Elecraft] Anti Static Bench

2016-01-24 Thread Edward R Cole
In my hamshack (spare bedroom) I have my electronic workbench which 
is a 4-foot Sears workbench with tool cabinet to which I extended the 
top with a 3-foot piece of particle-board shelving held up with big 
shelf brackets to the wall.


I built my KXPA-100 kit with anti-static matt lain on the bench top, 
yesterday.  If there is suitable prop on 20m today, I will check into 
the Elecraft Net with it driven by my K3/10.  Have not, yet, 
connected the KX3 via the optional control cables.  I was surprised 
that the amp was driven fully with only 3w from the K3/10 on HF; 
takes 8w on 6m for 80w.


Also surprised with its size; very suitable partner with the KX3 (or my K3/10).

73, Ed
PS: we were shaken up early this morning by 7.1 earthquake about 80 
mi sw of us.  Mostly stuff knocked off shelves and loss of utility 
power for a few hours.  It did snap the drawer runner for one of my 
drawers in the bathroom.  There was a 6.4 earthquake 2-seconds later 
5-mi from the first so we got the combined jolts - lasted about a minute.

Rich,

I agree with Alan - there is no information about the "ESD qualities" of
that top.

You may have better luck if you contact a local cabinetmaker and ask him
to build a top using laminate (like a kitchen countertop) to whatever
size you want.  Then get a proper ESD mat from a good supplier and place
it on the workbench top.  That is what I use, but I built my own (I ran
a custom woodworking shop to 10 years, so constructing such a workbench
was not a chore for me).  The ESD mat does not necessarily have to cover
the entire workbench, only the working area.

I suspect the total cost will be less than the workbench top you were
looking at.

Don W3FPR

Very similar to the MFJ is the Arrow satellite beam: 3-elem 2m/6-elem 
70cm.  You can assemble only the 2m elements if you are noise source 
hunting.  KX3 on batteries is excellent radio to use.  Add a step

work well.  I'm sure there's other equipment and methods available as well.

[Elecraft] Soldering Station Recommendation

2016-01-24 Thread Dauer, Edward
On the advice of Jim, K9YC, I bought a Hakko to build a K2 recently, along
with a couple of tips of different sizes as Don, W3FPR, suggests.  Worked
great.  I haven¹t built a K1, but based on my experience with a K2 I would
strongly recommend you buy a ³solder sucker² as well.  Very inexpensive,
works amazingly well, and saves a great deal of embarassment.

grounded. If you wax the floors use an antistatic wax. Use only pink or
silver antistatic bags such as Elecraft uses. Leave the ZIP lock bags in
your kitchen. BTW if you are one that thinks that ESD devices must be in a
certain narrow range of resistance, measure the resistance of an antistatic

I then laminated 1/8 masonite on a solid core door, routed the edges and put
oak edge banding on just for grins to make the bench tops. I also but blocks
under the legs to make it taller for a stand up bench.

Take a look at my qrz.com page for pictures.

It saved a bunch of money over a standard lab type workbench and I had fun
making it. A standard countertop or similar would go on the legs easily,
they just screw onto the bottom. The legs are very sturdy. I just put ESD
mat on the work surface area. The edge banding was not the best idea, it
tends to chip easily. I connected my ground system to the metal legs, maybe
it helps as a counterpoise, maybe it makes no difference.

I then laminated 1/8 masonite on a solid core door, routed the edges and put
oak edge banding on just for grins to make the bench tops. I also but blocks
under the legs to make it taller for a stand up bench.

Take a look at my qrz.com page for pictures.

It saved a bunch of money over a standard lab type workbench and I had fun
making it. A standard countertop or similar would go on the legs easily,
they just screw onto the bottom. The legs are very sturdy. I just put ESD
mat on the work surface area. The edge banding was not the best idea, it
tends to chip easily. I connected my ground system to the metal legs, maybe
it helps as a counterpoise, maybe it makes no difference.

Re: [Elecraft] Antennas with resistor and OCFD.

True rhombics are hard to rotate. Even harder is finding the space to put
one up in the first place. See what your HOA has to say about it.

Ummm ... rhombics *always* work well for their intended use. 
Unterminated, they are bi-directional.  With the terminating resistor, they
are unidirectional in the direction from the feedline to the terminator.
Since terminated rhombics are usually 2 or more wavelengths on a side, they
have very narrow beamwidths with a big F/B ratio, low radiation angle, and
high gain.


Quite so but it's worth noting that the unidirectional characteristics
obtained with a terminating resistor did not result in any additional gain.
Instead, the resistor absorbed the RF that would have been radiated on (or
received from) the reciprocal heading, giving the array its unidirectional
characteristic.

Yagi's, quads and similar arrays gain a stronger main lobe by suppressing
radiation in other directions.  

A rhombic is a classic example of how the best design is not always the
design that radiates the most RF. 
The problem with a rhombic for Ham use on the HF bands is that they tend to
be an absolute beast to try to rotate.

Re: [Elecraft] Anti Static Bench

2016-01-24 Thread Fred Townsend
Richard I have worked with some of the most static sensitive parts in the
world, tunnel diodes. When working for NASA we had to do a failure modes
analysis on any parts that failed. I would say the quality of the ESD
material ranked at the bottom of factors to take into account. Particularly
since any top would be used in conjunction with an antistatic mat. The mats
do wear out in the sense that the rubber dries out and they tend to crumble.
Other than that I find they all do the job.  There is wide latitude. 
In terms of tops you do not want such as metal or any slick plastic or vinyl
surfaces where things slide. I think the ones we used were either wood or
composition. I think your ESD top would be fine.
Some of the little things are very important. Don't use storage bins with
little polystyrene trays for anything. (I like muffin tins.) Likewise keep
Styrofoam out of the room. I have measured 5KV on a Styrofoam cup that had
coffee in it. Our pot cores came packed in Styrofoam. We had the stockroom
unload them and repack in metal trays. Keep the humidity in the range of 40
to 60%RH. Wear only cotton clothing and make sure your soldering iron is
grounded. If you wax the floors use an antistatic wax. Use only pink or
silver antistatic bags such as Elecraft uses. Leave the ZIP lock bags in
your kitchen. BTW if you are one that thinks that ESD devices must be in a
certain narrow range of resistance, measure the resistance of an antistatic
bag. You'll find the range is way out of sight. The trick here is not to
generate ESD rather than dissipating ESD after you make it.

I agree with the previous responses. ESD material does wear out, especially
in my dry climate. It has to be replaced once in a while.
In commercial operations is is tested on a schedule and discarded if it does
not pass. It has to be conductive enough to keep parts from damage and
resistive enough to not allow a shock.

I would like to offer another option.

Home Depot will sell you workbench legs, I bought these but they have
several sizes. They were shipped free
