[Elecraft] Elecraft CW Net Announcement

[kevinr]

Good Evening,
 The weather has changed a great deal over the last week.  The 
mountains are preparing for the deluge of winter.  It is very dry here 
as can be seen by all the fires filling the Columbia River Gorge with 
smoke.  The coming rains will clear the air and hopefully help the 
firefighters contain the grass and forest fires.
Propagation has also changed.  This week it was tougher copy than 
during the previous week.  However, on Friday my sked worked quite 
well.  Hopefully that will presage good conditions for tomorrow.

Please join us tomorrow afternoon and evening.

1) Hail signs  (first letter or two of the suffix of your call)
2) NCS help  (as well as QSP/QNP  help)

Sunday 2200z (Sunday 3 PM PDT) 14050 kHz
Monday 0200z (Sunday 7 PM PDT)  7045 kHz

Stay well,
   Kevin.  KD5ONS

Re: [Elecraft] [K3] Subreceiver IF output

[Mark n2qt]

For another approach look at
http://www.pvrc.org/Newsletters/jun12.pdf
and in the files section of the Yahoo  K3 user group.

This uses a small preamp from Clifton Labs to provide isolation and some 
gain if
desired.

Thanks Ian, and with complete instructions too. Now I just wonder how it
compares to the KXV3A output - I know there was a mod that made the IF
signal on the main receiver much stronger, I'm not sure if a similar one
applies to the sub as well.

[Elecraft] Tucson Hamfest

[Dyarnes]

Hi All,

The Tucson area hams have made a concerted effort to upgrade our annual 
hamfest.  Today was the day.  This year they somehow encouraged several 
vendors, including Elecraft, to make an appearance, and I think it all went 
extremely well.  Maybe a bit light yet, but if they keep working at it, I 
think this could become a really great event.  Congrats to the local area 
hams who made it possible.

The venue this year was the Marana Regional Airport, which is adjacent to 
Tucson.  This was perfect for Eric Swartz, who many of you know has his own 
airplane.  Eric simply flew in, jumped in a rental car with his goodies, and 
came across the runways from the FBO where he parked his plane.  Probably 
there was a detour in there somewhere, but it was very handy nonetheless.

Texas Towers was there as well, as were several other, smaller vendors. 
This is just a start at upgrading our event, but with continued, and 
hopefully increased, support, we may have something really good going here.

The Elecraft display included remote operation from Eric's home station 
using the K3/0.  Very slick!  Eric even has software that allows him to 
control his KPA-500 at home, in addition to the K3, and it was just really 
fun to see.  Of course the KX3 was prominently displayed, as was the new 
KAT-500--Eric says that will start shipping very shortly!  Sure hope so, 
since I have one on order to complete my K-line.  I'm really excited about 
it.  I'm also pretty stoked about remote operation, since I have a perfect 
situation for taking advantage of it when we go to Oregon in the summer 
months.

Eric was pretty busy, but we did have a chance to chat a bit more than we 
are able to at places like Dayton, which is a constant madhouse.  I've 
always been extremely impressed with Eric's management of Elecraft, along 
with Wayne of course, and our brief chat only reinforced my high opinion of 
how well things are going.  It's pretty obvious that these two guys are 
having a lot of fun, running a great company, and full of ideas.  When I 
casually mentioned that it might be hard to keep coming up with new "toys", 
Eric's eyes just  lit up, and I knew there were lots of things to come. 
These guys really have their "act" together, and we should all feel pretty 
good about it.

I also got to visit with an old friend, Gary Surrency, who I haven't seen 
much of (even though he lives in Phoenix) since he went to work for 
Elecraft.  As you may know, Gary is a very big part of Elecraft's tech 
support team, and a crackerjack technician at that.  I think he mentioned 
that he had been with Elecraft for 13 years now!  That's amazing to think 
the company goes back that far, but my K2 serial number confirms that!!! 
Gary and I first met when we were forming the Arizona ScQRPion group.  He's 
an original "charter member", as am I, but he's also been super busy ever 
since.  Anyway, I think a lot of Gary, and if he happens to be on the other 
end of a problem you are having, you are in great hands.

Anyway, it was a very enjoyable day, and hopefully one we will be able to 
repeat many times in the future here in Tucson.  57 years of this ham radio 
stuff and I'm still having a blast!

Dave W7AQK

[Elecraft] [K3] Subreceiver IF output

[Thomas Horsten]

Hi all,

I am using the K3 IF output extensively for I/Q downconversion and
panadapter display. The IF Out connector makes this very easy.

But it would think it would be very useful to have a separate I/Q stream
from the subreceiver (e.g. for monitoring a separate band, or a different
segment of the same band). I'm wondering if a mod would be possible to
allow access to the 2nd receiver IF, and if anyone has done this.

Re: [Elecraft] KX3 antenna

It's a Maldol AH-C14 20-meter loading coil and AH-R telescoping whip. Total 
length is about 48 inches. There was a thread on this topic in the KX3 yahoo

[Elecraft] Capicator Size for filtering across battery power

[goldtr8]

Gents,

My setup uses four ()4 12v batteries in parallel for powering my K3 and 
SGC powercube amp that I float with a battery maintainer.

I believe that I have an RF problem with the power setup.   I have put 
chokes in the power leads to the equipment but at certain times I can 
hear the ferrites buzzing with either the digital code being sent of 
matching my voice with SSB.   The chokes are clamp on types.  I am not 
observing any RF problems or reported problems on the air.  But I think 
that something is not right as of yet so I want to go after it to make 
my shack even better.

It has been suggested to me by a ham on the air that batteries just pass 
this thru as they have no filtering capability.   His suggestion is to 
but a bit CAP across the batteries to kill this phenomenon.

So my question as I am not an EE by education is how would I properly 
pick a CAP size and would different materials that CAPS are made out of 
make any difference.

It would be easy to go out and get a large CAP like used on car stereo 
systems but I want to have a better shot of fixing it right than just 
hacking away.

As always thanks in advance for your help.

Re: [Elecraft] KAT500

[Don Wilhelm]

Hal,

I understand your frustration, but one of the BIG tasks of Field Testing 
is to review the manual and offer suggestions for change. As a result, 
manuals are not available until the last days of Field Testing are 
completed.  There is more than just proof reading, the phrasing in the 
manual must match the average ham's mindset and be understandable 
without ambiguity.  That usually requires that the reviewer must have 
the hardware available as well as the manual.

Some of these cable and connection questions might be answered if only

a week,
I, again, urge Elecraft to make available early a pdf file of the manual.

All of us can help proof read it! ;-)

P.S.  To save Elecraft the hassle of shipping, I would love to pick up

Re: [Elecraft] KAT500 + AUX Cable

[iain macdonnell - N6ML]

Hi Bill,

I hadn't planned to get one (I made my own cables for both KPA and
KAT500), but if I do find myself ordering from Cable Wholesale, I'll
include one of these and try it out. I've had good experience with the
company in the past - including the HD15 splitter that many are now
using on their K3s.

[Elecraft] [K2] FS K2/10 for sale

[Don Wilhelm]

I have a K2/10 with KSB2, KAT2 and KIO2 available for sale.

This is Serial Number 1095, but has been fully upgraded with all mods 
installed and new IF filter crystals and the KSB2 filter width changed 
to the more recent 2.4 kHz bandwidth.

I will align the filters to your chosen sidetone pitch, and configure 
the microphone configuration header to your choice of microphones.

I will also offer a 90 day warranty on it - if anything fails, I will 
repair it and you pay only the shipping fees.

If these kits were to be ordered new, the total would be $1129.80. I 
will sell it shipped to anywhere in the US for $800.

No manuals are included, but you can download the manuals from the 
Elecraft website or order a new manual from Elecraft.  This K2 is better 
represented by the new manual than the original.

A cable with all 15 pins connected straight through (and not shorted to the
shield, or anything else) should work fine as the second cable, from the
KAT500 to the KPA500.

Good morning gang, 
I got meet and talk with Eric this morning at our local hamfest/fly-in at the 
Marana Regional airport northwest of Tucson ! Just wish Wayne could have been 
there also, Eric said he was slaving away back at Aptos !
 
 
It was real pleasure to meet and talk with him thou, you couldn't ask for 
nicer, more friendly guy if you wanted ! He had a nice display set up with the 
KX3, K3 remote (in operation), and the K Line !
 
 
I've spent time on the phone with Wayne about my KX3, s/n 45, and he was just 
great to work with ! 
 
 
So it all boils down to a great couple of guys, with a terrific support staff, 
along with great products and customer support ! Thanks again guys, you have a 
customer for life here !! 
 
 
And thank you Eric for your time this morning

By paying attention to the discussions here and looking at the Elecraft
web site occasionally.  For example, a picture showing the rear of the
KAT-500 has been there (http://www.elecraft.com/news.htm) for more than
five months.  I saw a prototype in Orlando last February and Dayton in
May.

Re: [Elecraft] KAT500

[Dick Dievendorff]

Hi, Phil,

You need one 15-pin ACC cable from K3 to KAT500 and another from KAT500 to
KPA500.  The KAT500 has two 15-pin connectors, one in and one out.  See
N6TV's back panel picture at
http://www.elecraft.com/KAT500/kat500rear_visalia.jpg  the connectors are
labeled "Control" (XCVR and AMP).

This arrangement allows the ATU to interrupt the amplifier key line during
tuning. It's a serial component to component chain, not a star, from the K3
to the KPA500.  The KAT500 wires each pin of the 15-pin connector to the
equivalent on the other, except that the amplifier key line goes through a
relay.

If you use two 15-pin ACC cables, you do not also need an RCA connection for
"PTT RLY" or amplifier key line.  The amplifier keying line is duplicated
within the 15-pin cable.

For amplifier key line interrupt, you should use two 15-pin cables, or two
RCA cables (radio to ATU, ATU to amplifier). But you can't use one of each.
The RCA connectors and 15-pin ACC cables use different poles of a double
pole amplifier key line interrupt relay.

The ATU and amplifier both count transmit frequency, and both will operate
without this 15-pin connection.  The minimal connection for any radio
(including K3) and any amplifier (including KPA500) is a two-wire cable with
RCA plugs from radio to ATU and another from ATU to amplifier. 

When the KAT500 and KPA500 have band information (in the ACC cable), they
can band switch without transmission, which turns out to be very convienent,
particularly if band switch implies an antenna switch. The ATU returns to
the last-used settings on the new band and your receiver works better than
it might if the ATU were still tuned for the old band.

You won't need a Y unless you have other users of the ACC connector at the
K3 end.  Some of us use the Y at the back of the K3 for FSK, PR-6, antenna
switch band decoders and the like. You might eventually find a second Y
useful if your needs at the back of the K3 expand.  That ACC connector has a
lot of uses.

We don't currently show an order item for the 15-pin two meter cable
separate from the Y and the little amplifier key line interrupter that form
the KPAK3AUX kit. The cable required is the same.  While I don't know the
exact cost breakdown of the components, I would expect that the price for a
cable-only "kit" wouldn't be a whole lot lower than the KPAK3AUX kit.

The 15-pin cable in the KPAK3AUX supply is two meters long.  That's a lot of
relatively stiff cable to find a place for when the amp and ATU are one atop
the other (either way), although some find it goes down the wall OK.  You
might find a shorter cable (perhaps 6 to 12  inches) more to your liking. 

Phil, AD5X, used 10-conductor shielded cable and DB15HD connectors for his
KPA500 to MFJ ATU connection.  See his KPA500 review article. which includes
parts sources and part numbers.
http://www.ad5x.com/images/Presentations/KPA500%20Review.pdf  

The K3 owner's manual shows the 15-pin ACC connector pinout.  The
KAT500/KPA500 combination uses (at most) BAND0-BAND3, AUXBUS, Ground,
PTT/KEY, ALC, and Amp inhibit.  That's 9 wires, and you can use the shield
between the shells.

Gang,

Thanks to all who took the time to answer my question below.  I now
understand the need and the configuration.  Just to be sure I will repeat
below:

When running the K3+KPA500+KAT500 together, to achieve the band
following/switching features of the KAT500 you need an extra cable from the
K3.  Thus,

1.  Y-adapter placed on the back of the K3.
2.  One KPAK3AUX cable running from K3 (Y-adapter) to the KPA500.
3.  One KPAK3AUX cable running from K3 (Y-adapter) to KAT500.


I just checked the web site (Order page) and found that there is no KPAK3AUX
cable listed as part of the KAT500 section.  Of course there is with the
KPA500 but I thought that one came with a Y-adapter as well as the cable.  

Question: is there a KPAK3AUX cable by itself available from Elecraft or do
you need to buy the kit again that included the Y-adapter.  Seems to me it
would be cheaper if you could exclude the Y-adapter and that other little
thing they include.

[Elecraft] K3 Display Frequency Calibration

[Paul Kirley]

It appears that the folks who can't hear the wow-wow zero beat note are

failing to turn on SPOT as specified in the K3 Owner's Manual for
Method 2.

Zero-beating the SPOT sidetone against the signal doesn't require
hearing
low tones, only hearing the amplitude modulation (wow-wow) of the
sidetone
as zero beat is approached.  The variation in amplitude is easily
heard; 
it sounds just like severe QSB or "picket fencing."

The procedure works best if the monitor sidetone (SPOT) level is set
about
as loud as the comparison WWV signal, using the front-panel MON
control.

I frequently find it necessary to turn SPOT back on as I tweak my Ref
Osc.
For whatever reason, SPOT often turns itself off, at least for me.

A cable with all 15 pins connected straight through (and not shorted
to the shield, or anything else) should work fine as the second cable,
from the KAT500 to the KPA500.

Re: [Elecraft] KAT500 + AUX Cable

[iain macdonnell - N6ML]

Rich,

You would not want ANY keying line interrupters in a
K3->KAT500->KPA500 config. You're right that you'd have surplus parts
if you procured another KPAK3AUX kit. Maybe the cable will be made
available for individual purchase

Alternatively, this cable ($4.02) appears to have all 15 pins
connected straight through:

http://www.cablewholesale.com/specs/vga-cable/10h1-01206.htm

It looks like it should work.

Re: [Elecraft] k3 filter install

[Mike K8CN]

James,

The full procedure is a bit long for an email, but please see page 46 in the
current version of the K3 Owners Manual, which is available under Manuals
and Downloads at the Elecraft web page.  All of the filter setup functions
are accessed through the CONFIG menus.  There are 3 key steps to follow: (1)
Tell the K3 where to find the new filter (slot FLx), its bandwidth and its
frequency offset; for the 8 pole filters such as your KFL3A-400 there is
0.00 frequency offset, (2) Enable the filter for receive mode, and (3)
Activate filter loss compensation (typically 1-2 dB for the 400 Hz 8-pole
filter).  You shouldn't need to alter the Transmit Crystal Filter Selection
settings if you have already done this procedure with the stock 2.7 kHz
5-pole filter.

Enjoy the new filter!

73,
Mike, K8CN

Re: [Elecraft] KAT500

[Oliver Dröse]

Thanks to Iain and Dick for the clarification on AUXBUS working 2-way. Only 
saw it 1-way with the KPA500 yet. Still I have on mind that AUXBUS in 
general is an old Elecraft protocol and timing critical as per Wayne. But if 
it will work 2-way with the K3/KAT500 then of course no need for "a dit" to 
even recall the correct memory for the frequency slice.

The KPA500 can only act as an AUXBUS sender, but the KAT500 is capable
of both send and receive, as is the K3.

Both KPA500 and KAT500 include "BCD" inputs to support non-Elecraft
transceivers.

Re: [Elecraft] KAT500

[Phil Hystad]

So, I have not seen any documentation of the KAT500 and the only photo image I 
have see of the back of a KAT500 (on the Elecraft page is not that clear).

But,  you must be saying that there are TWO AUX adapters on the back of a 
KAT500.   Is that the case?

I am curious as to how the average Elecraft user gets to learn this 
information.  I have not found any KAT500 documentation that might describe 
these things.

Re: [Elecraft] KBPF3 Option - Main and Sub Receiver

[Scott Manthe]

Welcome aboard!!

You only need the KBPF3 if you want to listen to frequencies outside the 
amateur bands. My recommendation would be to remove the KBPF3 from the 
KRX3 and move it to the main receiver, but if you want general coverage 
RX in both receivers, then you'd need to install one on both receivers.

The KBPF3 has nothing to do with the K3's ability to listen to two 
separate bands simultaneously, only with general coverage RX, so with 
the K3 with the KRX3 installed, you can monitor six meters on one 
receiver and 160 on the other, if you'd like.

73,
Scott, N9AA

Re: [Elecraft] KAT500

[Joe Subich, W4TV]

No, no, no!

There is no Y adapter necessary.  Connect one Aux cable from the K3
to the KAT-500 and a second Aux cable from the KAT-500 to the KPA-500.

The Y adapter is only needed if one is connecting additional hardware
like the PR-6 (DIGOUT1 control) or an FSK interface (FSK and PTT).

Re: [Elecraft] KAT500

[Phil Hystad]

Gang,

Thanks to all who took the time to answer my question below.  I now understand 
the need and the configuration.  Just to be sure I will repeat below:

When running the K3+KPA500+KAT500 together, to achieve the band 
following/switching features of the KAT500 you need an extra cable from the K3. 
 Thus,

1.  Y-adapter placed on the back of the K3.
2.  One KPAK3AUX cable running from K3 (Y-adapter) to the KPA500.
3.  One KPAK3AUX cable running from K3 (Y-adapter) to KAT500.


I just checked the web site (Order page) and found that there is no KPAK3AUX 
cable listed as part of the KAT500 section.  Of course there is with the KPA500 
but I thought that one came with a Y-adapter as well as the cable.  

Question: is there a KPAK3AUX cable by itself available from Elecraft or do you 
need to buy the kit again that included the Y-adapter.  Seems to me it would be 
cheaper if you could exclude the Y-adapter and that other little thing they 
include.

PEH

 For a K-line, you'll want a 15-pin cable from K3 (after the Y) to
 the KAT500
 and another from the KAT500 to the KPA500.  The KAT500 interrupts
 the KPA500
 key line in that cable during tune, and both the KAT500 and KPA500
 observe
 the K3's BAND0 thru BAND3 lines.
 
 If you aren't using a K3, then the KAT500, like the KPA500, can
 sense band
 changes by counting the Tx frequency.
 
 But it's very convenient to band switch the K3 and have the ATU and
 amp
 follow without requiring a transmission. The ATU switches to the
 last-used
 antenna on band switch (or to a fixed antenna you configure).  It's
 nice not
 to have to send a "dit" to make that antenna switch happen.
 
 The manual is in progress.

Re: [Elecraft] Panadapter Software

[Don Wilhelm]

Bob,

There is more to the solution than "simple software"

Go over to the LP-Pan Yahoo group and you will find many answers to your 
request.
You will need some hardware as well as software.  An LP-Pan or Softrock 
receiver (with Clifton Labs Z1 buffer amplifier) to provide the I 
and Q outputs.  You need a good quality soundcard, and you can use 
PowerSDR-IF or NaP3 (recommended) or several other software applications.

[Elecraft] Panadapter Software

[Alpha76]

Does anyone have, or know of a simple Software Program that would run on
Windows 7 when connected to the IF Output of the K3. I need a very large
Panadapter output to drive a TV screen. Digital presentations are not
required, just SSB due to physical problems. Thanks for your
consideration.
73,
Bob,w5pvr

[Elecraft] KI3 to Quadra cable

[K2GN]

Who was looking for a cable for the K3 to drive the Quadra??

If you still need it, I got one made to N0SS specs.

[Elecraft] [KX3] first impressions

[M5FRA - Colin]

Been playing with the KX3 which arrived yesterday, it was well worth 
the wait. The RX is certainly VERY impressive, knocks spots of my 
TS-590S which was previously the best I had used. Will not be selling 
the Kenwood though. The biggest differences are RX noise and the 
filters. Not sure about the stereo effect audio, it takes some getting 
used to. There are one or two minor niggles but hey nothing is perfect 
and at the moment the KX3 is the closest to perfection of any rig I 
have used! Thanks Elecraft, for your superb customer service and for an 
truly excellent rig!

Re: [Elecraft] KBPF3 Option - Main and Sub Receiver

[Dick Dievendorff]

Yes, if you want to use both main and sub receivers on frequencies outside
the amateur bands, you'll want two KBPF3 options.

However I find I need just one general-coverage receiver. I have my single
KBPF3 option on the main receiver.  I use the second receiver for diversity
and split frequency operations only on the amateur bands.  

I don't think I'd use a sub receiver KBPF3 very often.

Your needs may well be different than mine. If you want diversity receive
outside the ham bands, you'll want both.

I am a new owner, and have much still to learn on this rig.

Do you have to install 2 of the KBPF3 Option boards in order to have both
primary and second reciever have General Coverage Receive filtering?

Mine appears to be installed in the second receiver, and throws an error if
config is set to show it installed in the RF (Primary).

I think the answer will be yes if you are to be able to monitor 2 separate
bands simultaneously, but would like to know for sure..

Re: [Elecraft] KAT500

[Dick Dievendorff]

Yes and no.  When the 4-wire BAND data changes, the ATU does retune on band
change to the settings for the frequency last used on the new band. This is
often close enough that the receiver works well.

Selection of the precise memory for the Tx frequency occurs (when the KAT500
is in its Automatic mode) on transmission. 

The ATU does not change settings as you move across the band while
receiving.  Same as the KAT3 in this regard.

Antenna selection yes, memory no. How shall the tuner know which frequency
you are tuned to and which memories it should recall? BCD data only encode
the band, not the frequency. With the bands "sliced" into several segments
for which tuning memories are stored (presuming the KAT500 works the same as
the KAT3 and KXAT3 - I would bet on it, hi) you *will* need to "send a dit" 
for the tuner to recognize on which frequency within a band you are and
which memory must be recalled.

Judging from the auto RF detection / band change routine in the KPA500 I bet
you will not even recognize the tuner's doing it. But that does not mean it
does not do it. ;-)

Re: [Elecraft] KAT500

“Wouldn't a single 15-pin to 15-pin DE-15 cable in addition to the first 
KPAK3AUX cable set be sufficient?73,Rich VE3KI”

Yes, this is correct.  You need a DB15HD M/F cable (SVGA cable) between the 
K3 and KAT500, and the normal DB15HD M/F Elecraft-type cable between the 
KAT500 and KPA500.  The KAT500 reads frequency (BCD) and interrupts the 
amp-keying pin as necessary, but also passes thru all pins from the K3 AUX 
connector.  So as long as you use the normal Elecraft-type aux cable between 
the KAT500 and the KPA500, the undesired pins are removed in that cable.  Or 
alternatively, you could use the normal Elecraft-type DB15HD M/F cable 
between the K3 and KAT500, and your own (or another Elecraft) cable between 
the KAT500 and KPA500.  Only one of these cables must have the appropriate 
pins removed.

Make sure that any non-Elecraft DB15HD M/F cable has all 15 pins passed 
thru, and no pins are shorted together.  If it makes you feel better, you 
can remove the unnecessary pins from a non-Elecraft cable between the K3 and 
KAT500 (you MUST remove these pins between the K3 and KPA500).  I have a 
short article in the “Equipment Modifications” section of my website 
(www.ad5x.com) on cable sources.  The cables I call out have all pins 
connected thru and no pins are shorted together.  As my KAT500 is located 
just under my K3 and my KPA500 is located more than three feet away from 
both, I use a 1-foot DB15HD M/F cable between the K3 and KAT500, and a 6-ft 
DB-15HD M/F cable (with the appropriate pins removed) between the KAT500 and 
KPA500.

Re: [Elecraft] KAT500 + AUX Cable

[Richard Ferch]

I was not actually asking about which lines needed to be connected 
within the cable, although that is another important aspect. I was 
simply asking whether it is necessary to purchase two complete KPAK3AUX 
cable sets. It seems to me that with two complete KPAK3AUX cable sets, I 
would end up with at least one surplus Y-cable (assuming I need the 
first one) and a surplus key line interrupter (or is it actually two; 
i.e., does the KAT500 even need a separate interrupter?).

Stated otherwise, I'd like to know whether the only way to purchase (as 
distinct from fabricate) the necessary additional 7-wire DE-15 to DE-15 
cable is to order another complete KPAK3AUX cable set, or whether it is 
possible to order the DE-15 to DE-15 cable on its own (on the assumption 
that that is all I would need, of course).

Rich VE3KI

Re: [Elecraft] KAT500

[Oliver Dröse]

As far as I know AUXBUS just works one way (see the K3/KPA500 integration). 
Otherwise there would not be any need for the BCD data from K3 to 
KPA500/KAT500, would it? ;-)

NO! Do NOT use a 15 to 15 DE-15 with all wires connected! Or at your own risk...
You should only connect AUX, BND0-4, Key line and ground.
Get an AUX-Cable from Elecraft for maximum confort.
Y-Cables are NOT suitable for this purpose, as stated in a previous e-mail.
You must daisy chain K3 -> KAT500 -> KPA500 with TWO (original!) AUX cables.

If not, you'll have to send RF for both to tune. And sooner or later, you may 
inadvertently tune at 500 Watts...

Re: [Elecraft] KAT500

[Richard Ferch]

This still seems to need some clarification.

Quoting from the KPAK3AUX Cable Set Instructions: "The KPAK3AUX cable 
set consists of three components: a 15-Pin to 15-Pin DE-15 KPA500-K3 Aux 
cable, a Y cable, and a Key Line Interrupter adapter." If I already have 
one KPAK3AUX cable set with my KPA500, are you suggesting I need a 
complete second KPAK3AUX cable set including all three components? 
Wouldn't a single 15-pin to 15-pin DE-15 cable in addition to the first 
KPAK3AUX cable set be sufficient?
