[Elecraft] HELP! XFINITY SHUT OFF INTERNET DUE TO HAM ANTENNAS

[Dana]

Questions:

1. is this coax?
2. do you use a cable modem?

I found on 160 m my cable modem kept resetting…
discovered the upstream side uses HF and above 30 Mhz!!!
Fix?  
Grounded the cable to my system ground (the existing cable ground was a joke) 
…put some ferrites on the cable near the modem.
as a precaution put the modem in a copper screened box for testing…
Reset cured -  … with proper grounding and ferrites….

You are Federally regulated, and so is the Cable company… so any issues are 
likely their plant or
the gear attached to their plant…..(ie cable modems with improper bypassing or 
disconnecte drop lines etc...

The towers stay, send that reigstered letter and CC ARRL….

Re: [Elecraft] KPA500 Clicking Noise

[Dana Roode K6NR]

Thanks for the suggestion to search for other discussions of this, hadn't
occurred to me.  I did some searches and everything I read suggests the
clicking is harmless.  Elecraft can supply a new "Z bracket" to correct the
problem.  It's even mentioned in the manual it turns out.

Am I missing something?

[Elecraft] KPA500 Clicking Noise

[Dana Roode K6NR]

I hadn't used my KPA500 for awhile, but I put it on the air recently.  It's
working fine with my K3, but after it warms up - 40 degrees C or so - I
start to hear a faint clicking noise.  It is coming from the vicinity of
the fan and heat sinks.  There is a click every 10 seconds or so, I think
whether I am transmitting or not.  Fan control is working fine, and I
bumped up the lowest speed to help keep the amp cooler.

Let me know if anyone has seen this before.  Meanwhile, I will keep using
it and see how it goes.

  Dana, K6NR

[Elecraft] Koss SB/45 vs Yamaha CM500

[Dana]

My CM500 died on me, looks like the electret element … I replaced the set with 
a Koss SB/45
which was cheaper and quite comfortable and plugs into the K3 as well (K4 too).
The price of the CM500 had doubled up here in Canada for some reason, so the 
Koss looked more attractive.

[Elecraft] K3 and DEMI/Q5 Transverters.

[Dana]

Just to mirror what Ed mentioned…
I have my complete 160 - 5G station running off of my K3 bought in 2011 and 
upgraded.
I have the internal 144 transverter which had to go back 3 times to get spurs 
sorted out.
One think I note, is signal compression as I have pagers just below 144 Mhz and 
when they fire up 
They desense the 2 m transverter….
I’ve correlated this with an SDR. The problem is lack of filtering in the 
internal transverter as the front end sees well beyond 144 - 148.
The solution was to add a filter with a steep rolloff below 144 Mhz… 

I would hope that the guys at Elecraft when designing the new K4 transverter 
system will take a cue from DEMI and Q5 and ensure adequate
Bandpass filtering in the front ends… I would think TOKO or similar are your 
friends on this … 

Just my 2 cents.  I use the 2 m to drive all my microwave stuff as well and 
with GPS locking its nice to be able to know where you are …

Having said that, Q5 have a really slick multi band transverter that would 
integrate really well on the K3 or K4… but at a price point.
Anyway I do hope Elecraft come up with something that is crunch proof and rock 
solid for 144 222 432 MHz.

[Elecraft] K3 on 6m

[Dana]

I use my K3 daily on 6 m but you need one of the preamps or a good GAsFEt 
preamp with it…for DX activities.
Its fine without for local stuff… especially in urban areas..

Re: [Elecraft] K3 Chirp - K3SYN Board

[Dana Roode K6NR]

The cause of my chirp is my K3SYN board; the intermittent nature was purely
related to what frequency I was on.  Turns out when I was on 14044.74, plus
or minus a little, the chirp was there, even when I was transmitting at a
few watts out.  I did the Config VCO Cal procedure Wayne mentioned, didn't
fix the problem, nor did reseating the board and doing the procedure
again.  There is a mod from 2010 or so to correct a problem like this, but
my board already has this done (r20 is 25 ohms not 50).  I have an older
K3, and I moved its K3SYN board to the newer K3, seems to work fine, no
chirp.  Meanwhile, I put the odd K3SYN in the older K3 and the chirp is
there, same frequency.

I'm not sure if I caused other issues when I swapped the boards, so if you
hear me on, drop me an email to let me know how its sounding.  The older
board doesn't have the metal plate stiffener on it, nor does it have the
2010 mod.

Meanwhile, I'm in the market for a K3SYN board.  Don't know if elecraft has
them as spare parts or can repair the one I have.  Will have to ask.

Let me give this another try.  Anyone out there ever have an issue with a
CW Chirp from a K3?   Mine seems to be intermittent, it's not always
present.  I've got a spare K3, I guess I will drive out to the station and
swap out the one there now.  If it's not the power supply, the only other
thing I can think of is an issue with the KSYN3 board.  I can try the

[Elecraft] K3 Chirp

[Dana Roode K6NR]

It was reported today by several folks who heard my CW signal that I have a
bad chirp - I was operating on 20 meters during CWT.  I listened to the
signal myself (my station is 80 miles away and I can listen on a local
transceiver).  Someone also sent me a recording.

I've been using the same K3, KPA1500, and Astron power supply for many
years.  I shut off the amp and could still hear the chirp.

One thought is that it has something to do with my power supply, although I
saw a previous posting that made that seem unlikely (below).  Wayne
mentioned something about KSYSN3 calibration, I had not heard of that
before, I will look into it.

If anyone has experienced a problem with chirp on a K3, let me know (it is
a K3 not a K3S).

  Dana

Under normal circumstances, it is impossible for a K3 or K3S for exhibit
"chirp." The synthesizer settles well before the rig switches from TX to RX
or vice-versa.

The KSYN3A (newer synth, used in the K3S) settles in well under 1 ms thanks
to its entirely digital architecture (UHF DSPLL, divided down).

The KSYN3 (older synth, used on the K3) uses a more traditional PLL with
its VCO running at the target output frequency. It normally settles in
under 5 ms. It can take a bit longer depending on the actual PLL voltage
and VCO frequency. This is accounted for in firmware.

If your KSYN3 were not properly calibrated, you might see a longer settling
time on one or two bands, most likely 6 meters. If you suspect this, refer
to the CONFIG:VCO MD menu entry. The K3 includes an automatic VCO
calibration routine that requires no test equipment and takes only a couple
of minutes to run.

When I got a "chirp" report one time (on a homebrew rig) and was unable to
hear it myself, I sent a friendly letter to the OO. He replied that he was
"almost sure" he could detect a "slight chirp" so he sent the card.

[Elecraft] KIO3B board ?

[Dana]

I got hit by lightning last summer and lost my KIO3 Rev B  - burnt inductors 
and 
Other damage.

One of the guys kindly sent me an Rev A version board, which I sort of got 
working, but
Its not quite 100% .
I had queried about surplus Rev B version boards, but lost the replies here, 
when I rebuilt my
Also damaged PC.

Does anyone have a Rev B version board set that they are not using, if you had 
upgraded to the 
USB sound card board KIO3B,  that they would be willing to part with? 

I want to see if I have further damage or not  or if its just Rev A vs Rev B 
related. 

Please let me know, as I try to diagnose the other “intermittent" issues…

Thanks 73

[Elecraft] K3 tx rx switching

[Dana]

I have an interesting question I hope someone can answer:

Im running a dual band amp - a very old Henry 6 N 2.
I’ve used it primarily on 6 m but recently got it tuned back up for 2 m as well.

I want to drive it with the K3 on both bands.

The input circuit for the amp as separated connectors for 6 and 2 however the 
Internal circuits of course all lead to the cathodes of the 8874’s. So when one 
drives
On either band there is RF energy cross coupling on either input. So the 6 m 
power would have 2 m RF on it 
And vice versa… 

Here is the question:   When the K3 switches to Transmit, do all the antenna 
ports switch 
Together or just the active port?

Also, wrt to the internal 2 m transverter, is it powered off when not in use, 
and does the receive port
See the outside world at all times… 

The reason Im asking is I don’t have 2 DPDT relays but can put switching 
together using multiple SPDT relays.
One the drive side however I have a nice dual SPDT relay that can switch both 6 
and 2 m RX and drive  but it only has
One coil so it would be active on either band… however this would put the 2 m 
RX line into the amp input at the same time
As 6 m so I suspect this would not be a wise idea…

Re: [Elecraft] Sudden KpA1500 power reduction

[Dana Roode K6NR]

Ok thanks everyone, I will lug the amp back home and contact Elecraft.  Ive
had it for about 2 years, everything breaks now and again.  I've got my
AL1200 here, I could use it at least when I'm here locally.  I can't count
how many times I repaired that amp.  But the KPA is above my skill level.

[Elecraft] Sudden KpA1500 power reduction

[Dana Roode K6NR]

I'm in the ARRL CW contest this weekend and the KPA1500 has been working
fine.  However, a few minutes ago I noticed I was getting about half the
output power on 20 meters that I typically get with around 30 watts drive
(about 600w vs 1200w).  PA current is less than normal, around 30a.
Similar problem on the higher bands, I can no longer get 1000w.  On 40m I
can, but it requires more drive.

Seems like something died in the amp; I'm not familiar with the design, but
perhaps an output module.  No errors or ill behavior from the amp other
than the loss of power.

I will contact Elecraft support unless there is something I'm missing
here.  I just looked in the archive and see that this has happened to
others  I use the amp remotely so I guess I'll have to take it home
with me.

[Elecraft] KX1 Receive Audio

[Dana Roode K6NR]

I have a KX1 that I hadn't used in awhile but I got it out recently.  Works
fine - made a couple of contacts with it - but the audio has some
"artifacts" at times.  Usually they are very quiet, and they  go away when
I hold the radio in my hand.  Some sort of odd grounding issue of some
sort?  I hear the artifacts even without an antenna.  It comes across as
clicking, almost always very quiet - you can hear it best if you turn down
the RF gain.

At any rate, the radio is quite usable but I thought I'd see if anyone else
has this issue.

[Elecraft] K3 CW Chirp

[Dana Roode K6NR]

Just finished operating the California QSO Party as K6VO.  I received a
report of a bad CW chirp and have a recording of how that sounded.  Has
anyone had any issues with K3s chirping?  At this point it's only reported
on 80 meter CW, so it may be RF getting somewhere.  I think my power supply
is good.  I have not been able to recreate yet listening to a remote
receiver.

Any initial thoughts appreciated.

[Elecraft] CW Sidetone and Line Out?

[Dana Roode K6NR]

I typically use a telephone connection for receive audio from my remote K3
as its one less dependence on the crummy internet I have.  That broke today
so I'm using audio over the Internet using DF3CB REMAUD program.  My CW
sidetone is loud no matter what I set "MON" too, and I've even experimented
with the "LINOUT" configuration; setting it to 0 removes my receive
audio but not the sidetone.

It seems sidetone is coming from LINOUT and I've not found a way to reduce
its amplitude.  Or I am not thinking about this right...

Any suggestions?

[Elecraft] K3 Transmit Timeout for Remote Operation

[Dana Roode K6NR]

I've been using my K3 remote for many years.  I'm using VNC to a
controlling PC to operate the K3 and a variety of other equipment.  I have
relied on an imperfect external solution to protect against runaway
transmission.

I've seen postings to the list over the years about a timeout that
tracks when the PTT is on and triggers TX Inhibit if its on more than a
defined length of time, resetting when PTT goes off.  Does anyone have a
circuit for this to share or other suggestions?  I imagine a 555 timer or
the like with the right interfaces to the K3.  I understand that some of
the Remote Radio interfaces have this built in, but I'm not using them.

[Elecraft] KI03 Damaged

[Dana]

HI all… 

My K3 suffered some EMP damage from a recent T storm… I’ve found L4 on the KIO3 
remote IO board open with evidence of heating on it….not sure what else may 
have been nuked.

If I turn on the radio with the KIO3 in  the radio boots up but then switches 
between TX and RX about 1/ sec … everything else seems normal.
If I try to connect via RS232 it just goes into TX … 

If I pull the board all appears functionally normal.

Has anyone experienced this similar issue when the IO gets damaged?

Does anyone have a spare KIO3 board that they may have pulled and saved when 
upgrading to the USB IO set up, or any suggestions as to what else may be 
damaged , like U1 ?

Thanks in advance

[Elecraft] K3 RS 232 Data

[Dana Shtun]

Im running my k3 with transverters up to 5.7 Ghz. Its running fine

I ran into a puzzle however with VE3NEA’s Omnirig, in 
that it stops reading at 1296 Mhz and doesn’t display anything 
higher.
Looking at the INI file doesn’t seem to show anything that 
should stop it.  
Has anyone run into this before??
I’m  wondering if its something hard coded in his program.
I’ve queried him but no response as yet.

[Elecraft] Ft-8

[Dana Smith via Elecraft]

Ladies and Gentlemen,

 I view FT-8 like stamp collecting.  You get the QSO you post it 
and you move on.  If you use eQSL you can download a QSL card of your 
QSO, admire it just like a stamp collection and have fun. It's not for 
rag chewing, just collecting.  I actually enjoy all modes of 
communication and my KX3 is great at all of it.

[Elecraft] Fwd: VHF+UHF Radio Wish List

[Dana Shtun]

I came across this “Mother of all switch units”  from Terry K8ZN o
f Directive Systems , and the Grid Pirates. I had read about it in QST and 
filed the idea away for future use…

Then I bought a K3!   and was pondering how to connect all my transverters, all 
from different manufacturers or Home brew..in a way that would take advantage 
of the K3
s great transverter tools!

This was the “missing link” for VHF UHF!

BTW:  The elecraft external band switch is ALSO very capable and will work on 
HF or VHF/UHF, but it requires a bit more hardware, however the HF guys have 
sorted all this out
and a lot of it is applicable to VHF UHF as well, but its not as compact as the 
MOASU.

With a bit of modification Terry’s board talks to the K3 via the RS232 port - 
the original design was computer driven via RS232.
This was featured in the World Above in QST in 2008  and here is the link
to the Grid Pirates web… http://www.k8gp.net/station-equipment/moasu or e mail 
Terry. He may have boards and parts left.It is capable of switching
12 bands…but the K3 can only handle 10 if memory serves.

I drive 2x24 V rotary switches from the board, one switches the 28 MHz IF from 
the K3 for 222 and 432, and the other uses the 144 Mhz IF for my microwave 
transverters, plus 144 and 50
as well there are on board relays that move a Demi 4 port sequencer from band 
to band via a set of 3 phono plugs per band, on the back.
Ive also modified it to provide 12 and 24 V switched output for relays and
also integrated a G4FRE / WW2R band decoder board into it just to give me a 
full frequency display… ie 2304.1000 rather than 304.1000 on the K3.

It all works great, I can jump from 50 through 2304 just by switching bands on 
the K3.

I will never part with my K3, unless I go with a k3S that is….

[Elecraft] Fwd: VHF+UHF Radio Wish List

[Dana Shtun]

If you look at the schematic for the internal transverter there appear  to be 
available pins for “stacking” tranverters and switching the IF around…
similar to what exists with the external transverters.

Which means if there were transverters you could add them internally…222, 432, 
902, 1296… 
The biggest feature would be band specific sequencing and lines to sequence 
amps, and preamps...

Sure would make my life easier… but I’m using the "Mother of All Switch Units" 
to control all my transverters and sequencing.
This talks directly to the K3. Makes VHF contesting so easy but its rack 
mounted, would look better in a Elecraft style cabinet! jo

If I took out the 100 w module there would be room to fill the box with 
transverters….but a K3SVU would be nice eh?

[Elecraft] Fwd: SSB Monitoring

[Dana Shtun]

I noted posts regarding EME echoes, 
we had a problem at VE3ONT with the Algonquin Radio Observatory 150 foot dish
operation in 1994. We were running an 8877 into the dish so our ERP was a few 
MW on 144 Mhz. 
Every time we sent a test SSB signal we got QRMed 2 sec later
with a 20 over S9 signal just offset from our transmit frequency… same thing on 
CW
.. haha … it was US causing the “QRM”….. 

I have a K3 and its the best radio I’ve owned, and the customer service 
is out of this world! Just missing the “big dish”….

Hello Everyone,
I would like to know what is the maximum length of cable on a K-POD, we 
can use.
The reason is that I want to use it from another room in my house...of 
course the K3S is in one room, and sometimes I want to listen on the 
radio...remote...with Ham Radio Deluxe.in another room.and I 
would  like to be able to use my K-Pod ...

Thanks

Did RU this past weekend and could not get KIO3B to XMIT-Receive is fine using 
MMTTY and N1MM. Ended up using my Signal Link for XMIT.
Here is what I know.
NO line in or out connections on back of radio (per earlier email I saw)
Radio control, frequency, etc. work fine-just updated firmware
USB Codec shows as USB Codec 3 on computer. I can see AFSK produced in transmit 
on MMTTY screen and the silly meter in the sound control window. but no audio 
reaches radio
DATA Mode is set for AFSK A (like I have always used it for SIgnal Link)
Even if I manually turn XMIT on no audio IN. (I am using VOX and not PTT) Do I 
need to enable PTT?

I have tried switching MIKE to LINE IN to no avail.

What am I missing? Any help here would be appreciated.

OT: but I am going to add a couple cpu fans to the heat sink of my 
KXPA100 which will be installed under the backseat of my truck.  That 
will ensure a little more cooling.  The seat sets down on top of the 
fins so the fans will be positioned to feed from one end.  The 
enclosure will be drilled with multiple 3/4 inch holes for airflow.

I will only run SSB so that is low duty-cycle.  The internal overtemp 
protect will engage if it gets too hot.

[Elecraft] KX3 SWR indicator

[Dana Browne via Elecraft]

Oops, pressed enter too soon.

I neglected to mention that the only additional board I have in the KX3 
is the antenna tuner, I do not keep batteries in it, and the serial 
number is #150, so a rather early model.  I was unable to find anything 
in the KX3 manual about the SWR meter, but I recall seeing something 
posted on the reflector about it being pretty reliable.

[Elecraft] SWR indicator

[Dana Browne via Elecraft]

I have noticed on my KX3 that the SWR indicator gets progressively less 
accurate on the higher bands.   I have the antenna tuner installed, but 
when I put it on bypass, I see into a 50 ohm dummy load


15m 1.2
12m 1.4
10m 1.5
6m 2.1

I have used two homemade dummy loads and one commercial one, and the 
readings are repeatable.  I have checked all three loads against my 
antenna analyzer, and all of them show 1.1 or less on all those bands, 
6m having the largest SWR of 1.1.


Should I be concerned about operating on 6m, given the faulty indicator? 
 Is there some testing I can do, such as removing the antenna tuner and 
repeating the test?


Thanks in advance.

[Elecraft] [K2-KPA100] Hi Refl

[Dana Phillips]

I have installed the 100w amp in my K2 and am in the final calibration 
stage but I have encountered a problem.  When switching in the amp 
stage, I get a Hi Refl message. This is problematic because I am 
transmitting into a  50 ohm commercial dummy load, and I have tried 3 
different coax jumpers with no effect.


Is there a setting for the SWR sensor that I am missing?  Is there a 
component or connection that I should check?


Thanks in advance
Dana N6DW

Re: [Elecraft] KX3 PBT on SSB

[Dana Browne AD5VC]

I am simply taking the headphone audio output (not the I/Q output) and running 
it into Digipan or Fldigi.This radio is just the stock radio with no added 
KXFL3 filter.  I just wanted to experiment with sound card audio on the KX3 and 
used the method that has worked with other radios.

I had not heard of the other demodulation scheme before.  I guess I have some 
more reading to do.

I will try the Data A mode.  Thanks for the feedback, folks.

 Hi Dana,
 
 The 1500 Hz hole in SSB mode is an artifact of Weaver
 Demodulation.
 Looking at the KX3 Firmware Information document, MCU 00.77,
 DSP 00.74,
 3-6-2012: IF the KXFL3 is installed, Weaver demodulation is
 enabled when
 HI-CUT is below 2.4 kHz.

[Elecraft] KX3 PBT on SSB

[Dana Browne AD5VC]

I have been using my KX3 with digital software and seem to have some odd 
behavior using the PBT.  I have it set to do upper cutoff/lower cutoff on USB 
or LSB and am watching the received display on the waterfall.  As expected, the 
upper cutoff in the noise follows the cutoff displayed on the screen, up to a 
point.

However, if I lower the cutoff below 2.35 kHz, there is an additional dead zone 
(no noise on the display) from 1.4 kHz to 1.6 kHz.   The same thing happens on 
LSU at 2.45 kHz.   This appears no matter what band I am on, so I assume it is 
something in the DSP software.

No such dead zone appears if I raise the lower cutoff.


I am using MCU 1.36 and DSP 1.05.

Has anyone else observed this?

Re: [Elecraft] KPA500 Serial 0194 Done!

[Dana Roode]

Hi Bruce, built my KPA500 (# 166) last Sunday afternoon.  Had a pause
when I fired it up for the first time and got a fault - had the top
off, easy fix.  I too was short flat head screws for the top cover,
but found enough in the spares bag.  My LEDs lined up ok with my
finger.  No problem with ribbon cable.

 A few observations:

 LEDS
 Metering LEDS not very straight or level, was somewhat disappointed with the

 job on the LEDs, many are not installed in line or level. Tempted to touch 
 that up
 myself as I have a nice rework station, but thought I'd call Elecraft first. 
 I won't care
 so much if it were something like the W1 wattmeter, but on a product the cost

 Anyone else notice this?

 Missing Hardware
 I'm short almost all of the flat head screws for the top.
 Thought I misplaced a bag, double checked, I was very
 careful to measure screw length though out the build.
 Anyone else have a problem with this?

 Ribbon Cable
 Anyone short the ribbon cable for front display?
 I remember these back in the days of the early PCs,
 think you can just pop off the back plastic cover
 and punchdown the cable at another spot.

 Love the product, these are just some feedback points and questions.

[Elecraft] KPA500 Remote

[Dana Roode]

Folks - who out there has set up their KPA500 as a part of a remote
station?  I'm planning to do so here, and wondering whether others
have used the pins in the AUX cable or plan to use software commands
to turn the Amp on and off, etc.  It appears both may be options.
There also appears to be a pin in the Aux cable that indicates a fault
condition, which would be handy to monitor remotely (I have a
LP-Remote board from N8LP).

I need to make a custom cable between the K3 and the KPA500 to connect
some lines (band indication, auxbus?) and bring out others - the ON
pin for the K3 that I currently use, the toggle ON/OFF pin for the
KPA500, etc.

So, what are others doing?  I see there are options to connect the KPA
to the K3 via RS232 not sure what that would buy me.

Re: [Elecraft] KPA500 Remote

[Dana Roode]

Hi Dick, thanks for the information.  What is the RS232 (XCVR)
connection on the KPA500 for? Its why I am some misperceptions about
connecting the K3 to the KPA.

At this point I see I can control the KPA via its RS232 port but for
some reason I am inclined to use the control pins on the KPA AUX plug,
which seems to be the other way to go.

 There isn't an option to connect the KPA500 to the K3 via RS-232.  There's
 an option to connect the KPA500 to the K3 via its 15-pin ACC connector.  If
 you use that cable, the K3 can track band changes initiated by the
 amplifier, the amplifier will track K3 band changed without requiring
 transmission, and it includes the amp keying line and the ALC voltage.  This
 connection also includes an AUXBUS connection that the KPA500 can use to
 send fault indications to the K3. And the K3 can automatically adjust its
 output power based on its knowledge of the amplifier being in operate.

 The KPA500's PC serial port should instead be used for your remote control
 program, which could be the KPA Utility, or someone else's remote control
 program.

 When you use the KPA500 and don't switch the back panel power rocker switch,
 the front panel on/off button (and the equivalent software command) turns
 off the high voltage power supply, but leaves the microcontroller running.
 The microcontroller runs in its boot block code and part of that code
 recognizes a software power on command.  The KPA500 Utility Operate page
 uses this technique for its remote control power turn-on.

 If you require the KPA500 to be really, really off, you should first press
 the front panel power button to turn the amp off.  Then you can remove all
 power by switching the back panel rocker switch or interrupt the KPA500's AC
 supply.  It's a good idea to let the amplifier close down in a controlled
 way (press its front panel power button, physically or via a remote control
 program) so that it has a chance to write its current state into EEPROM and
 also dump HV filter capacitor energy into the fan. If you don't do this,
 you'll see fault table entries (using the KPA500 Utility's Fault Table
 display) showing uncontrolled power off events.

 Nice callsign, Dana!

Re: [Elecraft] KPA500 Remote

[Dana Roode]

Dick,

Thanks - I went back and read the manual and I see it clearly explains
what the RS232-XCVR jack is for.  Sorry, I missed that.

Ok on the advantages of the RS232 port, I will hook that up.  I run my
remote station with an 8 port terminal server, and have one port left
(I control the rig, 3 rotators, LP-Remote, LP-100 watt meter, and
Winkeyer).  I have control over the power to the amp to shut it off if

 If you want to control the amplifier remotely, you'll probably need to
 connect its PC-side serial port to some remote control program.  The KPA
 Utility (as one example) shows you the amplifier's output power, SWR, PA
 voltage, PA current, temperature, monitors for faults, displays the current
 fault, has a button to clear the current fault, changes bands, switches
 between standby and operate, and turns the amplifier on and off.  You can't
 do many of these things from the ACC connector.  You can do some of them by
 remote control of the K3 (like change bands).   You can pulse an ACC pin to
 simulate pressing the front panel power button. You can change the amp's
 band by controlling the transceiver remotely and transmitting. You can
 observe that some fault has occurred, but you can't read the fault code
 through ACC.  There's no pin on ACC to switch the amp between operate and
 standby, or clear a fault.

 Hi Dick, thanks for the information.  What is the RS232 (XCVR) connection on
 the KPA500 for? Its why I am some misperceptions about connecting the K3 to
 the KPA.

 At this point I see I can control the KPA via its RS232 port but for some
 reason I am inclined to use the control pins on the KPA AUX plug, which
 seems to be the other way to go.

 There's an option to connect the KPA500 to the K3 via its 15-pin ACC
 connector.  If you use that cable, the K3 can track band changes
 initiated by the amplifier, the amplifier will track K3 band changed
 without requiring transmission, and it includes the amp keying line
 and the ALC voltage.  This connection also includes an AUXBUS
 connection that the KPA500 can use to send fault indications to the
 K3. And the K3 can automatically adjust its output power based on its
 knowledge of the amplifier being in operate.

 The KPA500's PC serial port should instead be used for your remote
 control program, which could be the KPA Utility, or someone else's
 remote control program.

 When you use the KPA500 and don't switch the back panel power rocker
 switch, the front panel on/off button (and the equivalent software
 command) turns off the high voltage power supply, but leaves the
 microcontroller running.
 The microcontroller runs in its boot block code and part of that
 code recognizes a software power on command.  The KPA500 Utility
 Operate page uses this technique for its remote control power turn-on.

 If you require the KPA500 to be really, really off, you should first
 press the front panel power button to turn the amp off.  Then you can
 remove all power by switching the back panel rocker switch or
 interrupt the KPA500's AC supply.  It's a good idea to let the
 amplifier close down in a controlled way (press its front panel power
 button, physically or via a remote control
 program) so that it has a chance to write its current state into
 EEPROM and also dump HV filter capacitor energy into the fan. If you
 don't do this, you'll see fault table entries (using the KPA500
 Utility's Fault Table
 display) showing uncontrolled power off events.

 Nice callsign, Dana!

 Elecraft sells a Sealed Lead Acid (SLA) Gel Cell battery for the K2.
 Unfortunately, many people, even some battery vendors, are careless with the
 terminology.

 There are at least two types of Sealed Lead Acid (SLA) batteries: those in
 which the electrolyte is in a gelatin form (Gel Cell) and those in which the
 electrolyte is liquid but confined by an Absorbent Glass Mat (AGM). This
 latter type is often called a Starved Electrolyte battery.

 Unfortunately, many people fail to distinguish properly between an SLA AGM
 battery or an SLA Gel Cell battery and call both types Gel Cell. It is
 true that neither will leak liquid acid, but they have quite different
 performance characteristics.

 SLA Gel Cells are superior for heavy demand and deep discharge situations
 since more electrolyte is available to support the chemical reactions, so
 they are the most popular no-maintenance, no-spill battery for powering Ham
 rigs.

 To further confuse the issue some liquid acid no maintenance batteries are
 referred to as SLA or Sealed Liquid (rather than Lead) Acid batteries. If
 punctured or otherwise damaged, these are capable of dumping liquid acid
 just like any earlier lead-acid battery. Like the older lead-acid batteries,
 they are properly classified as flooded batteries. So, when seeing SLA,
 it's good to know whether the L means Liquid or Lead.

 It's no wonder those in the transportation business are often skittish about
 shipping any kind of lead-acid battery. It's not always easy to identify
 exactly what it is by just looking at a label.

Re: [Elecraft] KRC2 - More than one antenna per band? Aux outputs?

Ok on the transverter angle, I understand now.

I have exhausted the LP-Remote's 16 relays for other control functions
(selecting receive antennas, powering on the K3, turning stuff on and
off).  One option was to continue a past discussion with Larry (N8LP)
about an expansion board, which LP-Remote has provisions for.   The
KRC2 was an option I was exploring, but I also have a Hamation relay
controller that may do the job for me.  It is a network based relay
controller and Hamation has modified the software to allow me to
control the relay driver remotely.  Now, I need to set it up.

Re: [Elecraft] KRC2 - More than one antenna per band? Aux outputs?

[Dana Roode]

Jack et al,

Thank you for your replies regarding the KRC2.  I may have missed it
in the discussion, but I don't recall anyone indicating how to control
the AUX outputs REMOTELY (using the F-Keys won't help me).  My station
is located 80 miles away from me, I would need to be able to do this
via RS232 commands to the KRC2, or to the K3 that trigger the proper
response in the KRC2.

I have a total of 8 antennas; my 80/160 meter vertical has two relays
that allow adding series capacitance or inductance; my 40 meter 4
square is steerable in 4 directions via 2 more relays;  I have
monobanders for 20 and 15, with a tribander I use on 10 and as a
second 20/15m antenna.  I have this all setup now using an old Kachina
product and a multiplexer I built but it is time to retire that
approach (http://roodes.com/k6nr/remote/index.html).

Probably not quite what the KRC2 is designed for, but I wanted to double check.

 The KRC2 in its standard configuration can easily select multiple antennas.
 When a new band is indicated by the radio, the KRC2 will select that band.
 The user can then select other bands through the F keys, sequentially moving
 up or down the antenna selectors.
 It is also possible to select alternate antennas using the Acc outputs as
 others have pointed out. This is easily done in the standard
 personality/configuration, again using the F keys.

 There are other possibilities in the KRC2 design that would allow for
 alternate antenna selection. Users have been very innovative in their use of
 the various ACC and XVT outputs in combination with the main band outputs to
 select antennas. It would also be possible to create alternate personalities
 for the device which show other behaviors. The KRC2ACC is an excellent
 example of this, providing significantly different behavior compared to the
 standard version. If the original poster (K6NR, I believe) is interested in
 this, he should give me a shout.

 I would be very interested as to why you think the KRC2 is not a good match
 for the K3, and what improvements could be made to improve this. The KRC2
 was originally designed to communicate with the K2 using the AuxBus or
 serial port. The K3 was designed to support the AuxBus to enable KRC2
 support. This is the primary method for K3-KRC2 band switching, although it
 is also quite possible to use the K3's serial port for gathering band and
 other information as well.
 As for the AuxBus signals, their definition is not public. Wayne has
 elaborated very good reasons for this. AuxBus system requirements are
 necessarily very strict, and if not handled properly could lead to rather
 severe problems within the K2 system environment.

 We are always interested in suggestions for improvements to Elecraft
 products. If anyone has suggestions for the KRC2, please give me a shout.
 Many product improvements come from the suggestions of the great customers
 Elecraft enjoys.

 Apart from using the aux outputs, which is probably the best method, you
 might also be able to fool the K3 that there are two 40m bands by pretending
 there is a transverter with a 40m IF that needs 100W of drive, has a 0MHz LO
 and is connected to the main antenna. Then use the KRC2 transverter outputs
 to select the relay.

 The KRC2 with the current firmware is not a particularly good match to the
 K3. Hopefully we will see new firmware soon but as you are remotely
 operating the K3, why not use a PC to select the relay with a USB relay
 board.

 If it is a fairly simple configuration the K3 has two logic outputs that
 could probably be used, either directly to control two relays.

 I take it you are aware you can also use the KRC2 buttons and its RS232
 port.

 Finally, if you wire up a toggle relay - e.g. via a flip-flop, you could
 make the relay alternate between antennas each time you select 40m.

 Does anyone know if the auxbus commands are published ? I believe there
 would be a market for 3rd party add-ons if it is. RS232 does not announce
 everything, so can't be used passively.

I used a K3 in the NAQP CW this weekend like others on the reflector.
I noticed a lot of noise on my 160 receiving antennas and was
surprised to find that turning the noise blanker off made most of it
go away.  On the other bands NB does not increase the noise but does
significantly on 160.  Anyone else notice this?  The noise is not at
all like what you get when you turn blankers on on other radios and
there are strong signals present, it just sounds like man-made noise.
