Re: [Elecraft] KPA1500 Enhancement

[Matthew Cook]

Now there's a good point, have to make sure the antennas are well matched
and put the tuner into bypass.

So time to get back to working on the 1500W W3NQN filter designs... and the
high power paperwork requirements from our regulatory body to run that sort
of power level... sigh.

Re: [Elecraft] KPA1500 Enhancement

[Erik Basilier]

Of course, in an SO2R scenario where the shared amplifier alternates between
two different bands with every transmission, a shared ATU would exercise the
relays a lot. Separate tuners might be needed in order to avoid the relays
wearing out.

the kpa500 with multiple radios a few days ago.
Hopefuly they are looking into pooducing one.
I have one I built but would prefer one the had the aux data switching in it.

Re: [Elecraft] For Sale, unbuilt K2 with many options

[Ken Allen via Elecraft]

Thanks for all the suggestions.  I received a quote several years ago from
one of the recognized builders but the  price was about 50% of my original
investment and was more than I was willing to spend.  I've had the full K3
line for a number of years and love the radio, so don't really need the K2.
I'm hoping to find someone who wants the K2 but doesn't have the $$ to buy
new.

You all are correct in saying the level of support available on this list is
amazing. I have benefitted from the list many times while learning to use my
K3, just by reading others posts. I got all the answers before I knew the
questions.

Getting old is a pain when it means we can no longer do some of the things
we love to do. The price you are asking for the set of K2 items would mean
you are taking quite a loss on the items you had bought.

One option to consider is to find someone you know and can trust to do the
soldering work for you. You can do the final assembly and alignment. At
least you will the satisfaction of having done some work on the K2 even if
it wasn't the soldering of parts that you originally expected to be doing.
You will also wind up with a nice radio that you can use on the air.

Re: [Elecraft] K3 P3 and KAT500

[Brian Hunt]

As far as I know ARES members only operate within the amateur band allocations. 
Your K3 should cover what you need as is. Maybe you are thinking about MARS - 
Military Affiliate Radio System who do operate outside of the amateur band 
allocations. For that you will need the radio software mod available from 
Elecraft with proof you are a MARS member. 

The KAT500 will handle all the power the K3 can output.

Re: [Elecraft] KPA1500 Enhancement

If that were to happen then adding a second 15-way connector at the same
time to said module to allow two K3/K3s to drive the one amp through each
respective antenna input and matched output would start this amp towards
the "basic" SO2R path.  From there a smart 2x6 antenna switching unit some
well designed BPF filters and your well on your way.  The rest of the magic
is then just firmware (says he that writes said firmware every day) within
the upgraded processor the KPA1500 has been blessed with.

Re: [Elecraft] My photos of the KPA1500 from Visalia, and a Y-BOX update

[Fred Jensen]

Although recently transplanted to NV, and really happy, I am a 
California Native, I did my childhood and teenager duties there, I 
graduated Cal Poly in Math there, and, after some travel thanks to the 
US Military, spent the last 40+ years in NorCal. I got my first ham 
ticket there in 1953, and I take great umbrage at the term "California 
Kilowatt."


I knew a couple of those guys, I saw their stations, one even let me 
operate when I was maybe 15, and it was nowhere close to 1,000 watts.  
Only exceeded when I got to work a little coastal marine at 5 KW.


Some terms just understate what the former generation could bring off 
... illegally. [:-)

Re: [Elecraft] OT: Package shippers

[Alan Bloom]

I've had exactly the opposite experience than Ken - excellent, flawless 
performance from FedEx and horrible experience with the post office.


The local post office claims to have found a rule that says that if your 
house is more than 1/2 mile from the public highway, they don't have to 
deliver packages.  So to save the driver the 5 minutes it would take to 
drive to my door, I have to make a more than 1-hour round trip to the 
post office and stand in line to pick up my package.


When I order on-line I always try to get it shipped FexEx, even if it 
costs more.  Unfortunately Amazon doesn't give you the option to specify 
the shipping company, so I have to have everything shipped to a friend's 
house in case it comes by USPS.

The radio world seems to be converging on your opinion, Ken. Almost all
packages I've received in the past few years have come via UPS and I use it
myself for my occasional outbound shipments. That being said, there is a
disturbing relationship between UPS and USPS: In some rural areas, and
maybe elsewhere, UPS can hand off a package for ultimate delivery by USPS.
Seems reasonable except that the two providers have different conditions of
carriage. UPS agrees to deliver to a home doorstep while USPS requires that
a home have an official USPS mailbox which they use when able. If USPS
delivers a package too large for the mailbox, then they will deliver to the
doorstep. However, if there is no mailbox, USPS will not deliver any
package of any size. They return the package to the sender, no notice to or
recourse for the intended recipient. UPS and mail-order shippers don't
disclose this occasional glitch (at least I've not seen it) so both
shippers and recipients get screwed. Moral of the story: If you don't have
a mailbox, don't order packages that will be shipped by UPS. Better, use
someone else's delivery address that has a mailbox. If you have a PO box,
some US Post Offices will accept courier packages addressed to their own
street address with an appended box number. But the shipper must specify
that street address because UPS will not deliver to a PO Box explicitly!
Catch 22.

In almost ten years she's had one package go astray, and
that was due to me typing a wrong ZIP code.  A Priority Mail
package will reach any US destination in no more then three
days.

FedEx is absolutely terrible!  One fat envelope of legal papers

of water.  Another was tossed over a fence into the yard.  Yet
another was dropped near the BACK door of the house.  Didn't
find it until a trace was instituted for the "missing" delivery.

When we order fabric, webbing, Velcro supplies, the vendor
is told in no uncertain terms if the order is sent vis FedEx it
will be the last one they get.  A gawd awful company! (:-)

FedEx problems may stem from their use of non-company
contract drivers in their trucks ... at least in this area.

UPS is OK in our view ... all of Rose's orders are shipped via
UPS or the USPS.

If you'd like to see what a KPA1500 looks like next to a K-line, start here:

and step through the next five photos by pressing the "right arrow" key on

After the last KPA1500 photo, you'll see K6VNA of Sign-Tek holding a Y-BOX,
with the nice new clear decal she produced for me to use on the top of the
cover, replacing the old silver labels I was using.  Thanks Vina!

Also, many thanks to WA6HHQ for letting me display the Y-BOX at the

Thanks, Lynn! That's a much more cogent explanation than I was able to
extract from either UPS or USPS the time it happened to me.

Ironically, that event ended up in my favor. Although I had to re-order my

saved quite a lot of money. Not something one can count on, though!

FedEx has th same arrangement.  It's good business for the Postal Service.

I recently ordered something from "the auction site" where the merchant
was insistent on "we do not ship to Post Office Boxes".  So I furnished
the street address, albeit reluctantly  because we access the "mailbox"
only infrequently because of its location.  What did the merchant to?
Sent it to that address by USPS!

Re: [Elecraft] A KX3 owner with a K3 or K3S question

Good observations all.  In addition, the K3 and K3S are FAR more 
convenient to use with data modes, because computer I/O can remain in 
place (at Line In and Line Out) without the need for replugging.

The easy fix for this is to go online to FedEx, generate the shipment,

cost. The same thing works for UPS. I also ship small stuff USPS. I 
always pack in my own boxes (I save boxes and bubble wrap) and take them 
to the local post office. Never any issues. There is a special place in 
hell for those who ship with packing peanuts. I've opened boxes and had 
them blow all over my property!


Delivery to homes seems to be random.  One package was left on top of 
a trash toter at the road.  While it was badly banged up by the trash 
truck, it ended up in the road and not in the truck, fortunately.


I live on a main road in the Santa Cruz Mountains. My mailbox is one of 
four adjacent to my driveway. I've not had this problem with UPS, FedEx, 
or USPS, but I and many of my neighbors HAVE had this problem with 
OnTrac. I've had their packages left outside in the rain, at the edge of 
the road, in my driveway, sitting on the hood of my car. Neighbors have 
had packages left at their mailbox, which in one case is nearly a mile 
from their house. Many of us have told amazon to never use OnTrac, and 
it's a reason that I haven't signed up for amazon prime.


As to delivery of UPS by USPS -- this business arrangement was

Thanks, Josh. I wasn't aware of this relatively new development, which

That may not be true for the KPA1500. It's pretty common now,

boost converter which smooths out the cap charging rate.


For example, the Meanwell RSP-3000 48V 62A supply, includes PFC and 
claims power factor > 0.95. Without PFC, might be PF=0.6 and certainly 
operate as you describe with high current peaks, big IR drop & I2R

Re: [Elecraft] For Sale, unbuilt K2 with many options

[Raymond Sills]

Hi Jeff:


Yes, there are several builders who will complete or build from scratch.  Even 
if there is nobody near by, Elecraft has a list of trusted builders.  Spending 
just a bit more to complete the radio will be a lot of value added: you'll have 
a great rig, and you (or your heirs) will be able to get way more than $1K for 
the rig.  And, there are people who would do the job just for the fun of it.


Plus, once the rig is finished, there is a lot of help here on this list.  No 
question is too silly.

Re: [Elecraft] My photos of the KPA1500 from Visalia, and a Y-BOX update

[Wayne Burdick]

The new amp is far smaller and lighter, has new LDMOS output devices, expanded 
display capability, additional rig/control interfaces including Ethernet, a 
separate power supply, much faster MCU with a lot more memory, more versatile 
fan control, redesigned cabinet that's RF-tight at all edges, and more 
monitoring/safety features. 

It also benefits from our many years of experience building K-line amps and 
ATUs.

Getting old is a pain when it means we can no longer do some of the things
we love to do. The price you are asking for the set of K2 items would mean
you are taking quite a loss on the items you had bought.

One option to consider is to find someone you know and can trust to do the

it wasn't the soldering of parts that you originally expected to be doing.
You will also wind up with a nice radio that you can use on the air.

Re: [Elecraft] K2 Distorted receive audio and low power output

[Don Wilhelm]

Denis,

Do you have the KDSP2 installed in your K2?  If so, check the DSP NR. 
If it is on, it can cause distortion.  It does an effective job of 
reducing noise, but does introduce some distortion - and may appear 
intermittent depending on the signals and their level.


If no KDSP2, then check the soldering in the PLL Reference area as well 
as the BFO area.  Marginal solder connections may have been OK in the 
past, but can fail after time.  Check the schematic for components in 
those areas and re-flow the soldering.


You can also do the Receive Signal Tracing as indicated in the manual. 
You may have to connect a strong signal generator as described in the 
Troubleshooting section of the manual.  An XG1 or XG2 will not provide a 
strong enough signal (the XG3 will), so construct the oscillator shown 
in the troubleshooting section of the manual.


The power output problem may or may not be related.  The best way to 
find the offending stage is to do Transmit Signal Tracing as described 
in the Troubleshooting manual appendix.  When you get to a stage which 
produces less than the expected values, that is the output of the 
failing stage, and you can investigate that particular stage for the 
problem.  Re-flowing the soldering may correct it.
Component failure is not the most common cause of failure (soldering 
is), so do not jump to conclusions about a component being bad - 
exception is if one of the PA transistors has been damaged.  If you find 
everything up to the PA transistor bases OK, then replacement of the PA 
transistors with the K2PAKIT from Elecraft may be in order.


73,
Don W3FPR

My K2 hasn't been used for a few years but, with the intention of taking it

The receive audio is intermittently distorted on all modes.  With a constant
carrier, it sounds like there is a warble to the note.  There is another
problem in that it has is that the RF power output is only about 6 watts
(it's the 15W version) and that seems constant on all bands.  I don't think
these two problems are related because the power is always low regardless of
whether the audio is distorted or not but thought it worth mentioning
nonetheless

[Elecraft] K2 Distorted receive audio and low power output

[Denis Jackson]

My K2 hasn't been used for a few years but, with the intention of taking it
out for a bit of SOTA work, I powered it up today.  Alas, I have a problem.

 

The receive audio is intermittently distorted on all modes.  With a constant
carrier, it sounds like there is a warble to the note.  There is another
problem in that it has is that the RF power output is only about 6 watts
(it's the 15W version) and that seems constant on all bands.  I don't think
these two problems are related because the power is always low regardless of
whether the audio is distorted or not but thought it worth mentioning
nonetheless

 

Any suggestions as to where to start looking for the cause of the RX
distortion?

I'll start: The old KPA1500 used 16 RF devices, the new one uses two.

Re: [Elecraft] OT: Package shippers

[Erik Basilier]

Don,

I, too have been through the procedure where I had to hand off the package
valued over $1000 to the driver rather than the store, and that was over a
year ago. The later  case of the expensive amplifier was just a few months
ago, and it was at a "UPS store" that I understand not to be an "independent
shipping center". Of course, the particular employee may have misstated the
limit, or I may have misheard. Regardless, my main point is that the rule
was so rigid. The fact that the employee was able to examine the empty
packing materials and see that they were customized and in good contition
made no difference at all. Such rigidity must surely end up costing the
customer, and it is up to the customer to determine whether perceived
reliability of the company is worth the extra cost. Although I have shipped
many packages, I bow to your even greater experience. BTW, once I shipped a
small package in the same store, in a box that was a once-used USPS Priority
Mail box. The employee berated me for using that box since it was supposed
to be used only for purposes of USPS shipping. I believe he was correct in
that such a rule exists. It doesn't make sense for USPS to allow their
freely handed out boxes to be used with other shippers. However, after the
original USPS shipment had been paid for and completed, didn't I own the box
and didn't I do a good deed by reusing the box? The fact that the box had
been used previously for USPS shipping was plain to see.

Erik K7TV

Erik and all,

I believe that amount is $1000 rather than the $100 that you quoted - unless
the particular packing store you used sets their own rules.
If you shipped at a UPS store, this new rule is unknown to me.

I do have a UPS account (but not regular pickup), and do not have a problem
with any package where the value is less than $1000.
If it is greater than that value, I can pack it, but I have to hand it off
to a UPS driver rather than dropping it off at a shipping center. 
The driver is required to sign a form for my records, and he takes
responsibility for it from that time.

Independent shipping centers that ship UPS are free to set their own rules,
and yes, if I take a package to one of them for shipment and declare $1000
or greater value, they will insist on packaging it.  That is fair, because
they share in responsibility for that parcel.

You learn those things after you have been shipping frequently for a while.

[Elecraft] PX3 Feature Wish List

[Scott Russell]

I posted this last week but I think it got buried by all the new
announcements.

A few PX3 feature wish requests:


   - The ability to add Center to one of the FN buttons.
   - Programmable band edge indicators. Could be like the MKRA and B lines
   down the display but a different color, like red. Also the ability to add
   band edge to the FN buttons.
   - More color options for the waterfall


Thanks,

Re: [Elecraft] OT: Package shippers

[Fred Jensen]

FedX places a top priority on businesses with whom they have shipping 
contracts, to the detriment of individuals.  My employer had a contract 
with them, practically everything went overnight, and the volume was 
"yuuge."  Nothing ever got lost.  I was on the road a great deal and 
regularly got envelopes at hotels, and in client's and partner's 
facilities.  I thought this was how the entire FedX world worked.  After 
retiring and having to use the FedX Store, I discovered:


It cost a LOT more to ship an envelope at the FedX Store than it did 
when I took it to work and shipped it with a company label.


Delivery to homes seems to be random.  One package was left on top of a 
trash toter at the road.  While it was badly banged up by the trash 
truck, it ended up in the road and not in the truck, fortunately.


Conversely, my wife and I "adopt" deployed troops and send them 
packages.  Since we started in 2002, we've mailed hundreds ... all USPS 
Priority Mail.  Not one has been lost, and we've gotten some photos of 
our troopers where we can see the package ... in about the shape it was 
when we mailed it.  We can even track them as far as JFK where they seem 
to fall into a military black hole. [:-) All the ones I've looked at got 
to JFK in two [sometimes one] days, to the troop in "The Stan" in about 
7 more.

Re: [Elecraft] OT: Package shippers

[Lynn W. Taylor, WB6UUT]

This is a UPS "service" that has a lower service commitment and a lower 
price than "UPS Brown."


It takes advantage of "consolidator" rates, with UPS delivering 
pre-sorted packages to a hub Post Office for final delivery.


FedEx has a similar service.

E-Commerce and mail order companies love these services because they're 
cheap, but the typical customer service agent doesn't know the 
difference between "UPS Brown" (delivery by UPS) and the cheaper UPS to 
USPS service.


Since the agent (or the website) thinks they're shipping standard 
Ground, they insist on a "real" address.  The company then uses the 
cheaper service, the package hits the post office and goes back to the 
shipper.


I've had good luck with the work-arounds in your post.  I usually put 
things like m/s  in the "company" field because some shippers 
"standardize" addresses, and the company name is usually unedited.


If you specify "UPS Brown" and the shipper follows instructions, you'll 
get the package from UPS, not through the Post Office.


This cheaper service is only available to larger shippers.  It's not 
available to consumers.

Regarding FedEx, I had one bad experience years ago, when they delivered a

items, always successfully. 

I agree that USPS has an excellent record of delivering packages undamaged.
For small packages they are also great on price, but not so much for bigger
items.

myself for my occasional outbound shipments. That being said, there is a
disturbing relationship between UPS and USPS: In some rural areas, and maybe
elsewhere, UPS can hand off a package for ultimate delivery by USPS.
Seems reasonable except that the two providers have different conditions of
carriage. UPS agrees to deliver to a home doorstep while USPS requires that
a home have an official USPS mailbox which they use when able. If USPS
delivers a package too large for the mailbox, then they will deliver to the
doorstep. However, if there is no mailbox, USPS will not deliver any package
of any size. They return the package to the sender, no notice to or recourse
for the intended recipient. UPS and mail-order shippers don't disclose this
occasional glitch (at least I've not seen it) so both shippers and
recipients get screwed. Moral of the story: If you don't have a mailbox,
don't order packages that will be shipped by UPS. Better, use someone else's
delivery address that has a mailbox. If you have a PO box, some US Post
Offices will accept courier packages addressed to their own street address
with an appended box number. But the shipper must specify that street
address because UPS will not deliver to a PO Box explicitly!
Catch 22.

Re: [Elecraft] K3 P3 and KAT500

[Matt Zilmer]

There is a Windoze-based app that unlocks TX up to 25 MHz, I believe. RX 
is already continuous up to 30 MHz, plus there is aRX segment at 44 to 
50 MHz, and finally 6m.


The rule used to be that you were required to send CS a copy of your 
MARS cert (or other authorization to operate), then they'd email a copy 
of the unlock program to you.  You can ask CS what's needed in your 
case.  The last time I unlocked a K3TX was in 2009 or so

[Elecraft] K3 P3 and KAT500

[KG7FYI]

Thanks for your attention. I've been running my K3 with pleasure. I have
several questions.

As a member of the local ARES I would like to unlock my K3 to access all
bands. My radio kit was built two years ago.
   1. Does my kit need a firmware update? I haven't been tracking that info.
   2. Is the software needed to unlock the bands freely available?
   
I have a couple of other radios for backup. What is the wattage limit on the
KAT500 tuner? 
Thanks for any help.

[Elecraft] For Sale, unbuilt K2 with many options

[Ken Allen via Elecraft]

I'm embarrassed to admit that I purchased my K2 kit, #5534, at Hamvention in
2006 and it is still not completed.  I worked on it right after the purchase
and then life got in the way when I was about to do the first power on
testing at the end of Part 1 assembly.   I built most of the added modules
first thinking I would start with the smaller, less complex boards.  After I
retired two years later, I picked up the kit again only to realize tremors
in my hands would not allow me to do the soldering any longer.  At this
point I have the following for sale:
 
Basic K2 - built to Part 1 of the assembly manual pg 42 but not tested
KSB2 - built - untested
K60XV - built - untested
KNB2 - built - untested
K160RX - built - untested
KIO2 - built - untested
KDSP2 - un-built still in box
KAT100-2 - un-built still in box
 
I also have the Rework Eliminators with appropriate changes made to the K2
assembly to this point.
 
EC2 - assembled - intended to have the KAT100 and KPA100 in the EC2. The
KPA100 kit is not included.
 
Also have the KRC2 - assembled and  used with my K3.
 
I have over $2000 invested. For all the above including shopping within the
continental US, I am asking $1000, but will consider reasonable offers.
 
Contact Ken Allen at kb...@yahoo.com with any questions or offers. I can
supply photos of the assembled item on request.

The radio world seems to be converging on your opinion, Ken. Almost all
packages I've received in the past few years have come via UPS and I use it
myself for my occasional outbound shipments. That being said, there is a
disturbing relationship between UPS and USPS: In some rural areas, and
maybe elsewhere, UPS can hand off a package for ultimate delivery by USPS.
Seems reasonable except that the two providers have different conditions of
carriage. UPS agrees to deliver to a home doorstep while USPS requires that
a home have an official USPS mailbox which they use when able. If USPS
delivers a package too large for the mailbox, then they will deliver to the
doorstep. However, if there is no mailbox, USPS will not deliver any
package of any size. They return the package to the sender, no notice to or
recourse for the intended recipient. UPS and mail-order shippers don't
disclose this occasional glitch (at least I've not seen it) so both
shippers and recipients get screwed. Moral of the story: If you don't have
a mailbox, don't order packages that will be shipped by UPS. Better, use
someone else's delivery address that has a mailbox. If you have a PO box,
some US Post Offices will accept courier packages addressed to their own
street address with an appended box number. But the shipper must specify
that street address because UPS will not deliver to a PO Box explicitly!
Catch 22.

[Elecraft] OT: Package shippers

[Ken G Kopp]

I suspect for each of us our view of shippers will vary widel.

While certainly not a "large" shipper, Rose (Elecraft Covers)
ships a number of packages a week, with many going to
foreign destinations.

She -always- ships via the USPS and mostly via Priority Mail.
In almost ten years she's had one package go astray, and
that was due to me typing a wrong ZIP code.  A Priority Mail
package will reach any US destination in no more then three
days.

FedEx is absolutely terrible!  One fat envelope of legal papers
from our bank was left on the driveway, laying in two inches
of water.  Another was tossed over a fence into the yard.  Yet
another was dropped near the BACK door of the house.  Didn't
find it until a trace was instituted for the "missing" delivery.

When we order fabric, webbing, Velcro supplies, the vendor
is told in no uncertain terms if the order is sent vis FedEx it
will be the last one they get.  A gawd awful company! (:-)

FedEx problems may stem from their use of non-company
contract drivers in their trucks ... at least in this area.

UPS is OK in our view ... all of Rose's orders are shipped via
UPS or the USPS.

Trivia:  A case shipped to Istanbul via USPS Airmail was
delivered in Turkey in -five- days!!

FWIW ...

73!

[Elecraft] Sub Receiver Antenna Switch

[wa9fvp]

The sub receiver connects to the AUX BNC or the ATU but not both. To correct
this I added a toggle switch and mounted it to the ANT3 position.  For my
application, I needed a way to switch between both inputs. At least for now,
I don't need the 2 meter module.  

Fortunately, I had spare TMP sockets and a short TMP cable that I pulled
from scrapped transceivers. I soldered the sockets to the toggle switch. I
plugged in two TMP cables to the outer socket.  One went to the AUX BNC and
the short TMP cable went to the TMP socket on the ATU. The center socket
went to the Sub RCVR BNC.  I wrapped toggle switch with copper tape. 

In the attached photo, so that I can get a clear shot of the toggle switch,
I disconnected the TMP from the ATU.

believe that even applies to wall warts.

This "power factor correction" will not be perfect, so the peak current
will still be more than for a resistive load.

Re: [Elecraft] Older option boards from K3 upgrade

[Guy Olinger K2AV]

The second K3 listing from top on the Sherwood (old syns) vs the first
K3 listing from top (K3 modded with new syns) is as good an A/B RX
test as you will ever get. Note: there is a separate K3S listing.
Print out the first page of the Sherwood listing in landscape mode,
and then fold the paper to put the two listing lines next to one
another.

It is quite true that many typical and ordinary ham situations will
not demonstrate the difference, but weak signal work on any band,
those improvements will make a difference, because phase noise is not
additive, it modulates band noise. This will have more effect on
signals from low signal RX antennas that are not pre-amped.

My K3 with the new syns is better in sound stage diversity, but that
is in the brain and I don't know the mechanism for the improvement,
hence entirely subjective. I suspect something related to allowing
band noise to come through less modulated by phase noise, but
absolutely zero proof.

On a diversity sound stage, noise is scattered around the "horizon"
with some discrete noise taking fixed positions. The noise sounds less
"muddy" with new syns, that's as good as I can describe that.

I'm still trying to find a series of attachments showing a progression
of phase noise on steady TX carrier with one at a time syn changes
between two close K3 owners. I'm now thinking it was on one of those
Tiny URL kinds of things and perhaps not widely distributed. I don't
have email with attachments regarding that synthesizer test.

And I'm one of the worst at figuring out the secret word to pump a
google search.

And yes, the diff in CQ shaping was obvious in seconds after syn replacement.

There is some stuff on Elecraft's Nabble searchable list showing A/B keying.

Re: [Elecraft] OT: What's The Best Way To Shp

[Don Wilhelm]

When equipment is damaged in shipment, it usually comes from movement 
inside that package, not from external damage to the package itself.


Your packing material needs to be tailored to the weight of the 
equipment.  Packing peanuts and bubble wrap are good for articles up to 
about 20 pounds.  With equipment heavier than that, you need something 
more substantial, like high density foam (not cushion grade foam rubber) 
to secure the equipment.


Those large packing "sacks of air" are not good for anything weighing 
more than a couple pounds.  If they receive much pressure, they will burst.


Think what will happen if the package comes to an abrupt stop at the end 
of a sorting conveyor.


I send and receive a lot of packages, and anytime I have observed damage 
is when the equipment inside has contacted the side of the package.
I have not found that one carrier is worse than another.  I use both UPS 
and USPS frequently, and on occasion FedEx.


If you have delivery problems, blame it on the local delivery person - 
baring some disaster in transit.  I currently have delays pending due to 
flooding in the area, but that kind of thing is not common.

Re: [Elecraft] A KX3 owner with a K3 or K3S question

Terry,

If you do much contesting or DXing, get an upgraded K3 or K3S.  You will 
find the operating conveniences worthwhile.


The K2 or KX3 can do the task, but it becomes easier and more versatile 
with the ergonomics provided by the K3.

Disassembly and reassembly of connections can get tedious when I am

SO2R done correctly requires extensive path shielding, switching components,

KPA1500 for all customers, while only a small percentage would make use of 
them. So we feel that an external controller providing SO2R or other 
specialized switching would be more appropriate.

KPA1500 firmware will be updated to fully support such products as we identify 
them. We oversized the microcontroller memory by a factor of about 8 to allow 
for such expansion. In addition to SO2R, there may be other gear such as 
antenna switches that we can directly control from the amp’s antenna and ATU 
switches, and status can be shown on the 32-character LCD.

I've had the best luck and quickest shipping with FedEx. It seems to me

be sure it takes 5 days, no matter how long it has to sit in a corner.

Some day maybe I'll better understand UPS's delivery system!  I 
recently received a package that came from Virginia via UPS.  Its 3rd 
stop was in Louisville, KY, where it then sat for 49 hours! Its 5th 
stop was in Phoenix, AZ (120 miles north of me), where it sat for 29 
hours!  Somewhere in between it apparently sat in the rain, as much of 
the "popcorn" packing was compressed and hard as a rock, and the 
documentation inside was stained, when I opened the package.  
Fortunately, the contents were well wrapped with waterproof material, 
so no apparent damage.  It's as if UPS wanted to make absolutely sure 
I didn't get my package quickly, or heaven forbid, early! Being 
somewhat cynical, I wonder if the extra delay in Phoenix was so they 
could let the box sit in the Arizona sun and dry out!!!


I may be overlooking something, but my best experiences, by far, have 
been with USPS, and particularly Priority Mail.  Unless a Sunday 
intervenes, I've never had anything take more than 3 days when shipped 
Priority Mail!  If you can fit it into one of their flat rate boxes, 
you probably are way better off.  Also, I've never had a Priority Mail 
package arrive with crushed corners as this one did!


Anyway, shipping these days is expensive and risky!  It still galls me 
that we have to pay premium charges for insurance against THEIR 
incompetence!

[Elecraft] KPA1500 Enhancement

[Thomas Donohue]

Hi to all:

Wayne or Eric. Are there any plans or thoughts about adding a second RF input 
to the amp, similar to what the Yaesu VL-1000 has? 

Best 73,
Tom/W1QU

Re: [Elecraft] Another really good reason to come to the Visailia DX convention this weekend...

[David Woolley]

I don't believe that it is legal to market a power supply that only 
draws current on input peaks in either the USA or EU these days.  Power 
supplies are supposed to spread the current demand over a significant 
part of the cycle.  I believe this is done by having a relatively low 
value capacitor on the mains side and relying on the switching regulator 
to compensate for the wide voltage variations across each cycle.  I 
believe that even applies to wall warts.


This "power factor correction" will not be perfect, so the peak current 
will still be more than for a resistive load.

The reason for using 240VAC is to reduce the IR drop in the AC line,
which, BTW, is not sinusoidal, but rather pulses that charge the filter

than Ohm's law appliced to a sine wave would predict.

Re: [Elecraft] KPA 1500 - SO2R

[Erik Basilier]

When the original poster referred to SO2R capability, I think he meant one 
amplifier being able to handle transmission from both radios. At 100W having a 
separate amp as part of each radio is no big deal, but at the price of a 
KPA1500, one really wants to pay for only one, given that SO2R means only one 
radio can be transmitting at a given time. 

I am just a beginner at SO2R, but I have already spent a lot of time thinking 
about various aspects of the subject. 

First there is the "SO2R controller" issue. There seem to be a lot of different 
designs out there, and they don't necessarily try to solve the same problem. 
Rather, different users seem to form personal opinions of what functions are to 
be implemented, and available implementations reflect that. Issues that may or 
may not be addressed in depth include routing of radio inputs, radio outputs, 
and radio controls, including interlocks to ensure that only one radio can 
transmit at a time.

Second, there is the configuration of the radio boxes. Normally the two radios 
operate on different bands. With 5 or 6 bands used in a HF contest, there will 
be many combinations of band choices for two transceivers. One can set each 
radio manually to the proper band, but sometimes one might want to use a 
central control to select a combination of bands rather than individual bands. 
When amplifiers are added to the picture, the situation becomes more complex. I 
have one KPA500, on the main K3. That works well if that radio is on say 40 and 
the second radio is on 15, since power is often needed on the lower bands, 
while 15 often doesn't need much power if open. Now suppose 15 closes and I 
want to go to 80 with the second radio. 80 might need the amp more than 40, so 
how do I quickly switch the amp over to the other radio? A similar situation 
would exist if I had two amp's with different power capabilities. The ability 
to "share" one amp between both radios would be very attractive. On the other 
hand, if I did not have that capability, but instead had a second KPA500 in 
addition to my existing one, I might in a given situation want to combine both 
for 40 while running barefoot on 15. Clearly, it may be shortsighted to address 
such individual capabilities individually, and from a manufacturer's standpoint 
it would make sense to have a generalised scheme of configuration, maybe with 
GUI software that allows the user to configure things by drawing and storing 
interconnection schematics. Of course, that is just the control side of it. The 
physical switching side, with proper isolation may be both complex and 
expensive. 

Third, antenna selection. One user may use many feedlines, while another tries 
to use only one. Antennas themselves may be monobanders or multi. I think most 
of us have been struggling with how to best utilize the fixed numbers of 
antenna connectors on different radios and tuners. What seems like ideal 
features to one user may seem totally wrong to another, even in a single radio 
scenario. With SO2R, we want to be able to select between several different 
antennas used by two radios. Isolation must be excellent so that neither radio 
will be interfered with by the other. The antennas themselves may sabotage the 
isolation by their proximity and configuration. The ideal station would perhaps 
have separate antennas widely spaced from each other. The average ham is more 
likely to use fewer,  multiband antennas. A typical switch box has two radio 
connectors and several antenna connectors, and it should not allow both radios 
to connect to the same antenna. In any case, the switching hardware operates at 
high power and is likely to be expensive. Ulitmately, it might be best seen as 
part of the expensive switching network that configures the radio box 
interconnections as discussed in the previous paragraph. 

To summarize, SO2R is a complex subject, and it is currently addressed mostly 
in a fractured way, using a conglomeration of hardware solutions to solve 
different pieces of the puzzle. There is such a diversity of user requirements 
that any "total solution" that would hypothetically be offered by any one 
manufacturer is likely to seem wrong to many potential customers, unless the 
archictecture is extremely advanced. Nevertheless, even a manufacturer that 
offers only pieces of the puzzle should over time gain an edge if its products 
supports major classes of configuration requirements.

I don't know if there is room in this forum to have much discussion of what 
features would be appropriate in future SO2R-related offerings from Elecraft, 
but previous posts have started to touch on the subject. Personally I would 
suggest that hams like myself with limited real estate and going to SO2R are 
likely to be using multiband antennas but still need antenna switching other 
than what may exist in radios, amplifiers and tuners. In other words, 
discussing how many connectors a radio or tuner should have may be a

Isn’t 14060 the QRP frequency on 20M?

If you'd like to see what a KPA1500 looks like next to a K-line, start here:

https://bit.ly/KPA1500atVisalia

and step through the next five photos by pressing the "right arrow" key on
your keyboard, or clicking on the circled arrow that appears on the right
side of the photo when you move the mouse over the image.

After the last KPA1500 photo, you'll see K6VNA of Sign-Tek holding a Y-BOX,
with the nice new clear decal she produced for me to use on the top of the
cover, replacing the old silver labels I was using.  Thanks Vina!

Also, many thanks to WA6HHQ for letting me display the Y-BOX at the
Elecraft booth, and also saying some kind words about it during his "New
Product Showcase" slide show at Visalia, where the KPA1500 was clearly the
star of the show.

P.S. My Y-BOX web site now needs some photo updates.  Meanwhile, I'm
working my way through the existing Y-BOX waiting list.  I appreciate the
patience of all those who signed up already.  You should be receiving an
email and invoice from me within the next two weeks now that Visalia is
over and I can get back to assembling.

[Elecraft] A KX3 owner with a K3 or K3S question

[Terry Brown]

I am the current owner of a K2 and KX3 with all the add ons possible.  I
also have the PX3 and KPXA 100.  I am happy with my setup.  It is the finest
rig combination that I have had in 35 years as a ham.  I love it's
flexibility for operating portable by using only the KX3, or with the PX3.
Disassembly and reassembly of connections can get tedious when I am
operating portable often and have to make the switch back and forth.

 

I keep reading all the great things about the K3 and K3S.

 

I also see that there are now good opportunities to purchase a used K3, many
with the upgrades to make them more like a K3S.

 

 

For those of you who have KX3 and a K3 that has been upgraded to have most
(not sure what is not possible to upgrade) of the features of the K3S,  What
does the K3 as far as receive performance and other key features have, that
are an improvement/enhancement over what I have with the KX3?

 

The reason I ask, is that if I ever have additional funds available, I am
trying to figure out if it would be advisable to upgrade to a used K3 that
has been upgraded, and buy a P3, and use my KX combination for more portable
use.

 

I just don't know if it is worth buying a used K3 and P3 when I have the KX3
line.   I know I am the one who would have to make that final decision, but
I would welcome any thoughts by current upgraded K3/P3 owners who also have
the KX3.

 

Thanks,

 

Terry de N7TB
