[Elecraft] K2 For sale

[Glenn Haffly]

The following K2 is for sale: Serial # 7429 with the following options:
K160 RX 160 meter and receive antenna , KNB2 noise blanker and KDSP2 DSP
filter. The DSP filter is no longer available. Included are all manuals
plus the alignment probe , Alignment tool , RF probe for troubleshooting
and a power plug. Case is a 9 out of 10 . Rig has not been exposed to any
smokers.
Current CW filter widths are 1.55 K  , 700 , 400 and 100 . Filters aligned
with Spectrogram. The 4 MHZ oscillator aligned with a frequency counter.
The only reason for selling is I have another K2 as a built rig and another
K2 in kit form.

I will throw in an assembled KSB2 SSB option. This was not built by me nor
is it installed in this rig. Board appears to be completely assembled but ,
I have no way to test it. Can only suggest to check it out carefully before
installing.

Asking $800 for all and I will ship. Paypal is OK

[Elecraft] Elecraft CW Net Announcement

[kev...@coho.net]

Good Evening,

   The sun has been active this week.  But it appears we are leaving a 
stream of solar wind.  That should mean a refreshed ionosphere with 
improving conditions.  I have been known to be wrong on occasion.  Being 
a hopeless optimist is not easy.


   That ground hog was right.  I have had continuous snow since early 
December.  I will get at least another week more.  Today it went from 
almost bare to three inches.  More Sunday, Monday, Tuesday, etc.  
However, the first flowers are blooming which has to mean something.  
Time to clean the hummingbird feeders.


Please join us tomorrow on:

   14050 kHz at 2300z Sunday (3 PM PST Sunday)
7045 kHz at 0100z Monday (5 PM PST Sunday)

73,
Kevin. KD5ONS

[Elecraft] Setting Mic Gain to ALC

[Bert via Elecraft]

I haven't used my K3 in an SSB contest in ages, but I've used my  KX3 
often. I just discovered this problem with the current ARRL DX SSB contest.  I 
can't set the MIC gain so I have 5 (+/-) bars on the ALC meter (with the last  
bar "wiggling"). It seems to be an all-or-nothing situation. There must be  
up be some setting I've fiddled with that changed everything, but I can't  
figure it out. The meter is either at "max" or zero...no gradual increase 
using  the MIC gain knob.
I'm using a CM-500 headset plugged into the rear panel MIC jack.  The MIC 
SEL is set to rP.H bIAS (rP.L won't show any "bars" at  all!). MIC+LIN is set 
to ON...makes no difference when set to  OFF.
 
I'm getting good audio reports, but I just don't feel comfortable  without 
the "wiggling" last bar in the ALC "meter".
 
Any ideas?
 
Bert, N4CW

Re: [Elecraft] RX antenna & carrier-operated relay

[Don Pomplun]

Didn't I see something about "protectors" built into the K3S antenna 
connectors?  Are they like the transient discharge tubes that protect 
(somewhat) against lightning?  Is there also one on the RX antenna input?

Fabio,

You've seen my antenna farm -- Beverages run within 20-30 ft of my

the sub-RX. I don't do anything special to protect the radio, but it 
does occasionally protect itself. I also use the Beverages on 80, 40, 
and 30M, but TX antennas are much farther away (more than 100 ft). 
This is at 1.5 kW with a Ten Tec tube amp.


BTW -- I just added a pair of VE3DO loops tuned for 160M and aimed to 
EU.  Each loop is a rectangle 40 ft long and 10 ft vertical, with the 
bottom wire 2 ft off the ground and fed at the center. Details on 
OK1RR's website. The two loops are spaced 5/8 wavelength (350 ft). You 
probably don't have room for two loops, but you might fit one of them.

Hi Dave,
thanks for the suggestion.
I tried doing a quick measure using a cross-needle SWR meter today,

On 40m the power appears to just deflect the needle, well below the 0.5W

I usually have an external relay in a box to disconnect the RX antennas
while transmitting, but not today.
I was thinking why the RX antennas remain connected when transmitting if
there's not another use in a typical single-op station.

Re: [Elecraft] KX3/KXPA100 Change

[Don Pomplun]

Elecraft CS suggested wiggling the RJ connector, too, but I found the 
problem was wiggling the 2 plugs at the other end of the cable.


Also [egg on face] I once had one of those plugs plugged into the RX I/Q 
jack instead of ACC

Re: [Elecraft] Lost Cursors

[Bob Wilson, N6TV]

Are you in Fixed mode or Tracking mode?  Do you mean VFO Cursors or Markers?

Do you see a little purple triangle at the edge of the screen indicating
that the VFO B cursor is off the Edge of the screen?

Be sure to set MENU:FixMode to something other than Static.  I also
recommend

MENU:FixTrack Fixed
MENU:FixMode Half span
MENU:Cursors BAR

So the cursors are always easy to see.

Also, make sure MENU:VFO B is ON otherwise the VFO B cursor is never shown.

Re: [Elecraft] KPAK3AUX cable

[Bob Wilson, N6TV]

I've tested many "VGA extension" cables that do not have all 15 pins wired,
or short several pins together as a common ground.  They work fine for VGA
monitors, but should never be connected to any Elecraft product except the
P3SVGA external monitor port.

Many VGA cables include connectors without pin 9, obvious by visual
inspection.   Thinner "monitor" cables with ferrite beads on both ends
usually do not have all 15 pins wired either.

DE15HD - DE is the shell size, 15 pins, HD means High Density (3 rows).

Search your favorite UK Supplier for Amphenol CS-DSDHD15MF0 (male to
female) or CS-DSDHD15MM0 (male to male).  These cables have all 15 pins
wired straight through.

[Elecraft] KX3/KXPA100 Change

[Carter Craigie]

Hello Fellow Elecrafters,
I have an Elecraft KX3, connected to an Elecraft PX3, and both are connected
to an Elecraft KXPA100 Amplifier, and to my Dell laptop computer.
All had been working well, and before leaving for an out-of-state trip, I
disconnected the antenna cable from the rig, as well as the power cable. I
may have disconnected something else, but all cables are now connected right
where they should be now.
Upon returning from the trip, and re-plugging everything, I can get no more
than 5 Watts out of the KX3.
The green LEDs illuminate on the KXPA100 Amplifier, and the Switch is in the
OFF position. The KX3 is receiving properly with good audio, and all signals
show correctly on the PX3.

On the KX3 the flowing menu items are set, as per the manual:

PA MODE: ON
RS232: 38400 b

The KX3 Serial Number is 4240. 
MCU Revision 02.38. RS-232 speed 38400 bit/s. Computer Port COM3.
DSP 01.37 RS-232 speed 38400 bit/s. Computer Port COM3.


The PX3  Serial Number is 1016.
MCU REVISION 01.39, RS-232 speed 38400 bit/s. Computer Port 3.

The KXPA100 Serial Number is 1515.
Revision 01.39. RS-232 speed 38400 bit/s. Computer Port COM3.

I'm stumped. Why can't I raise the power level up to 100 Watts, as I had had
it before?
Any help, please?
(If I have omitted any pertinent data, please ask me, and I can add them.)

73,
Carter Craigie, N3AO
Blacksburg, VA

[Elecraft] T-1 problem fixed!

[Irma Linas]

Hello group,

This might be usefull to all who own the Elecraft T-1 antenna tuner. Some
time ago I complained to this group and to the Elecraft support on problems
with T-1 had stopped tuning. The answer from the Elecraft  Support was
quick and extremely usefull! Please  find it below! Following their advise
I did check the resistance on diodes D1 and D2. It proved something was
wrong with the chain of the D1. The diode D1 though turned to be ok . The
faulty part was... the capacitor C11 wich was dead shorting the resistor R3
to ground. I replaced the capacitor C11 with a new one ( not SMD by the
way, the " normal" one) and bingo! The problems gone , T-1 runs smoothly
and quickly .
Hope this info is usefull for the T-1 owners and you do have the schematic
diagram of the unit in order to better understand the whole thing.

Re: [Elecraft] RX antenna & carrier-operated relay

[Jessie Oberreuter]

 The 2nd Rx port is on a relay, and not a particularly fast or quiet 
one in my K3.  I'd hate to operate QSK that way!  I could see a menu 
option that would activate it with a longer hang time, but you'd probably 
be better off with an external switch and/or front-end protector. -kb7psg

Hi guys,
  I was thinking of a possible firmware improvement related to the
carrier operated relay.
I use my radio on a small lot and recently I added a short beverage
antenna for low-bands receiving. My main activity is single-op contesting.
Because of the interaction between the tx antennas and the beverage, on
some bands I have the COR (carrier operated relay) activating when I use
high power.
I know the good solutions, but my point is different.
As I have the COR activating only when the RX Ant input is selected, why
doesn't the K3 firmware disable it when pushing the ptt?

In fact, when I push the ptt I don't need the RX-ant part to be active,
as I'm transmitting, and -at least in my setup- I have no other
rigs/devices that need that input (I mean, no in-band receivers and so on).
Instead of using external relays (ptt-activated) that cut out the rx
input when I am transmitting, why the K3 firmware just doesn't disable
the RX ant input on its own (and re-enables it if needed when releasing
the ptt)?
Maybe I'm missing something here, or that could be a nice improvement
for a next firmware release.

Thanks for any comment,
Ciao 73

Re: [Elecraft] External speaker for kx3?

[Walter Underwood]

Since this topic keeps coming up, I finally documented my speaker setup in a 
blog post.

It is simple, inexpensive (around $35), and fairly portable. I first put it 
together for a JOTA (Jamboree on the Air) station last October. It has been 
working great since then.

[Elecraft] KPAK3AUX cable

[Alan. G4GNX]

Fred Cady’s book on the KPA500/KAT500 combination mentions that if you’re using 
two cables to connect the AUXBUS signals between a KPA500, KAT500 and K3, it’s 
possible to use a DE15HD cable as long as the other cable is a KPAK3AUX cable 
wired as per the diagram. In the UK DE15HD is a bit of an obscure description, 
but I take it to mean a VGA EXTENSION cable (NOT A std. VGA cable) which has a 
male connector on one end and a female connector on the other end. I presume 
that these EXTENSION cables are wired pin to pin i.e. 1 to 1, 2 to 2, 3 to 3 
etc., Does anyone know if this is the case?

I realise that I would need a cable with all pins connected, then snip out the 
pins that should not be connected. I would happily buy another KPAK3AUX cable 
from Elecraft, but for an item which is readily available in the UK, it’s not 
really economical.

73,

Alan. G4GNX

[Elecraft] For Sale: 4-band KX1 (80,40,30,20)

[Phil Hystad]

I am selling my four band KX1 after much thought and consideration.  This 
little radio
has been a lot of QRP fun operating portable in various locations.

Description:

 — 80/30 option added by Don Wilhelm, W3FPR.
 — No internal antenna tuner.
 — Works excellent, no scars or damage of any sort.
 — Original documents included (KX1 plus 80/30 option)

Although no internal antenna tuner, I have the Elecraft T1 that I have used 
with 
various QRP radios and I may be willing to sell that too at the right price.

Price: $300  plus packing/shipping to CONUS Delivery only (or pickup Kirkland, 
WA)

Please respond if interested directly to my e-mail: phys...@mac.com off the 
Elecraft Reflector.

Re: [Elecraft] RX antenna & carrier-operated relay

[David Olean]

Hello Fabio

I have two beverages  that are somewhat close to my TX antenna. One 
had about 75 mw on it during TX while beverage #2 had about 1 watt! This 
is enough power to cause damage to preamps, so I made two power limiters 
and now the inputs are clipped at about 0 dBm. All it took was two 
transformers and two diodes in a box. Do you know what the power level 
is on your beverage during transmit periods?  Really high power levels 
could burn up the transformers.  Disconnecting the antenna is a good 
idea too.
