Thanks, Wayne.  I have both of these marvelous little rigs, and I learned about 
several new features here that I’ve never employed — but I will in the future.  
I was particularly interested in Dual Watch and Delay features, neither of 
which I’ve ever used in the past.  73 de Carl

Re: [Elecraft] SSB Features of the KX2 & KX3 You May Have Overlooked...

[Jim Brown]

Speech compression and EQ to get rid of the lower octaves of speech is a 
wonderful thing, and can increase "talk power" significantly. My 
starting point with TXEQ for maximum talk power is max cut of the three 
lowest bands (-18dB), 6 dB cut of the fourth band, 3-6 dB of boost on 
the top two bands. Do that BEFORE setting compression.


But EXCESSIVE use of compression can be a very BAD thing. I'd be very 
cautious about using more than an indicated 1-2 dB on voice peaks.  It 
should NOT be adjusted to a certain number on  the CMP readout, but 
rather to the meter that shows gain reduction.


Once these settings are done, get signal reports from trained listeners, 
and tell them to set their RX bandwidth fairly wide.


These two settings -- good low cut of voice frequencies and 10 dB of 
compression can increase talk power by 13 dB. That's multiplying your 
effective TX power by 20!

Hi Bill,

26 hours may be a record time for a basic K2 build. (I'll have to consult 
Guinness.)

If you do it again, you could aim even higher. Fastest K2 build in a moving 
vehicle? While listening to a presidential debate? Sans assembly manual? The 
mind boggles

[Elecraft] SSB Features of the KX2 & KX3 You May Have Overlooked...

[Wayne Burdick]

Our KX2 and KX3 transceivers have many standard features targeted specifically 
at SSB operation. Some are pretty much unheard of in other radios in this 
class. 

Just in case you missed them:


*** DVR (Digital Voice Recorder) ***

You can record and play back two 15 second DVR messages. These are especially 
useful during contests or SOTA operation, allowing you to store a CQ message, 
your call, or an exchange. To auto-repeat a played message, just hold the '1' 
or '2' switch rather than tap it. The auto-repeat interval can be set using the 
MSG RPT menu entry.


*** Speech Compression ***

Speech compression can add a lot of "punch" to your low-power signal, bringing 
up average voice power. As with the K3/K3S, our KX-line compression algorithm 
is exceptionally clean. Use the CMP switch on the KX3 (TX CMP menu entry on the 
KX2) to dial in compression of up to 30 dB.


*** Receive and Transmit EQ ***

8-band graphic equalizers (MENU:RX EQ and TX EQ) can be used to tailor the 
receive and transmit audio to your liking. 


*** Built-In Mic (KX2) ***

The KX2 is the world's smallest all-HF-band, all-mode "HT". Using the built-in 
mic, you can operate the KX2 like any handheld. Tap XMIT to transmit.


*** ESSB (Extended SSB) ***

If you're on a lightly used band and would like to experiment with 
higher-quality audio, give ESSB a try. It allows you to transmit with a 
passband of up to 4 kHz wide (wider than the usual maximum of about 2.8 kHz). 
Typically ESSB is used at both ends of a QSO, by agreement of both operators. 
(Again, make sure the additional bandwidth consumed doesn't interfere with 
adjacent signals -- e.g., don't use it in a contest.)


*** Passband Low/High Cut ***

When interference is heavy, you can often eliminate it by cutting the low or 
high end of the audio range. In SSB modes this low-cut/high-cut method is the 
default. Use the PBT I/II controls on the KX3, or tap FIL on the KX2 and use 
the two knobs above the switch.


*** Auto-Notch ***

If a carrier (sometimes called a "tuner-upper") appears, you can use remove it 
using auto-notch. Hold the NTCH switch on the KX3, or hold APF-AN on the KX2.


*** Noise Reduction ***

NR on the KX2 and KX3 can be adjusted using a single knob function, from 
completely a completely "dry" mix (no NR applied) to 100% "wet" (all NR). NR 
can relieve the fatigue of listening to weak signals on a noisy band.


*** RIT (Receive Incremental Tuning) ***

Many small transceivers don't provide this important feature. It is often 
called a "clarifier" because it allows you to tune in signals that are a bit 
off-frequency. The beauty of RIT is that it only changes your *receive* 
frequency, leaving your transmit frequency fixed. This is helpful if you're 
having a conversation with more than one station at a time, where each signal 
is a little off, such as on a net.


*** Stereo Audio and Dual Watch ***

The KX2 and KX3 are among very few radios that provide full stereo to the 
headphone jack. You can use this to advantage during normal operation by 
setting the AFX MD menu entry to "DELAY" -- this simulates stereo receive 
audio, giving voice signals a warm, rich sound. In dual watch mode (MENU:DUAL 
RX), you can listen to your VFO A and B frequencies at the same time, with VFO 
spacing wide enough to work most SSB DX stations operating split.


*** Custom VFO Coarse Tuning Steps ***

Using the VFO CRS menu entry, you can select coarse VFO tuning steps 
independently for each operating mode. In SSB mode, your choices are 0.1, 0.5, 
1.0, and 2.5 kHz per step. The default is 0.5 kHz. Bonus feature: If the 
OFS/VFO B knob is in the OFS setting (OFS LED lit), you can use the VFO B knob 
to move VFO A in coarse steps while leaving the VFO A knob itself set for fine 
steps (10 Hz). 


*** CW-In-SSB Mode ***

There are times when you can't quite complete an SSB QSO due to fading, and 
switching to CW has an advantage. With the CW-In-SSB feature turned on, you 
don't even have to change modes: just hit the key or keyer paddle and start 
sending. This feature is particularly useful on 6 meters with fleeting band 
openings. Many of have successfully completed (or initiated) a cross-mode QSO 
in this manner. To turn CW-in-SSB on, tap the PRE ('1') switch while in the CW 
WGHT menu entry.


*** MIC Bias and Switch Configuration ***

Just about any mic with a 1/8th (3 mm) plug can be used with the KX2 or KX3. To 
enhance versatility, you can turn mic bias on or off (MENU:MIC BIAS) and 
specify whether your mic has no switches, PTT only, or PTT and VFO UP/DN 
switches (like our model MH4). No PTT switch? Use VOX or the XMIT switch.


*** VOX (Voice Operated Relay) ***

This feature is missing from many small transceivers. It allows 100% hands-free 
operation for vehicle/bike/pedestrian mobile, or just for operating convenience 
with a headset/mic. You can turn VOX on/off, set the threshold, and dial in 
just the right amount of anti-VOX (VOX INH menu entry) to keep 

Re: [Elecraft] [K3] - Hum on SSB Transmissions

[Joe Rogers]

Hi Alan,

Thanks.

I saw you try to hit the reflector twice but nothing came through.  Thanks for 
that suggestion but I think I found the problem.  Looks like 60 Hz leaking into 
the mic from an open ground somewhere in the mic line to the headset.

You raise a good point that I had not considered.  I will keep it in mind in 
case I run into a problem in the future.

Hi Joe,

I twice tried to reply on the reflector, but both times the message posted with 
no text.  No idea what's going on.

Anyway, you might check if the problem could be hum getting into the mic 
mechanically.

At the community radio station I volunteer for we had hum on the desk mics in 
the main studio, but only when they were on the same table as the studio 
computer.  I finally figured out it was vibration from the fan in the computer 
transmitted via the table to the mics.

As an experiment you might try lifting the mic off the table.  If that makes 
the hum go away, then it's likely mechanical vibration.

The solution could be a shock-mounted mic or perhaps a boom mic mounted to the 
wall.

Hi Don,



You hit upon exactly what I did!!  When I last did on air checks, I had the 
Proset in the rear panel jack and had same hum as in front panel - which, as 
you pointed out, would indicate that the adapter was not the problem and the 
issue is in the Proset itself.



I am pretty much convinced it is in the Proset IC now.  I just cannot 
understand why after only about a year, I have this failure.  My prior Proset 
was 6 years old and no problem.  Anyway, I am talking to Heil and hope to get 
the whole issue sorted out.

Joe,



If you are using the Front Panel adapter for the ProSet-Ic, try plugging the 
microphone into the MIC jack in the back of the K3 and changing the MIC SEL 
menu to the rear panel.

If the hum is not present, then you have a bad adapter instead of a bad mic.

Joe,



Do you hear that hum when you operate into a dummy load?  If not, then check 
the common mode choke on the antenna, you are likely getting RF-In-the-Shack 
from the antenna - the fact that it diminishes when you put your hand on the K3 
amplifies that this may be the problem.  Forget about grounding the radio for 
this problem, solve it at the antenna feedpoint with a good common mode choke 
on the feedline.



Other possibilities are power supply ripple (run it on battery to check) or an 
open microphone ground lead (try other microphones).

Make sure the rear panel jacks are fully plugged (give them an extra push).

Don W3FPR

found several similar threads mentioning a hum on SSB transmit but of the

I have Heil Pro set IC and Heil Gold Elite.  The problem seems much more 
pronounced with Proset IC.



Whether it is connected to front panel (FP.H or RP.H Bias on) makes no 
difference.  If I used PTT or VOX it is there.  Set Mic Gain at anything above 
zero it starts.  With higher mic gain and higher compression it is worse.   I 
have made some PSK contacts using the LIN IN input and seems to work OK.

And if you ignore this rule, if you hear a lot of clicking after

a symptom of no antenna connected.

Re: [Elecraft] KAT500 antenna port grounding?

[Bob McGraw K4TAX]

The schematic shows a 1 Meg resistor to ground and a gas discharge 
device, SA1, SA2, SA3 on each antenna port.  Also when the unit is not 
powered, it defaults to ANT 1 in the Bypass mode.


Any lightning protection for your station should be accomplished outside 
of the house BEFORE the feed lines enter the structure. Once inside, 
it's too late.

Re: [Elecraft] K3S will not load or tune on 160 M/SOLVED

[Bob McGraw K4TAX]

As a rule for many reasons, if you do not use ANT 2 with an antenna 
connected then by all means, put a dummy load on it. Even a 10W or 20W 
rated load.    It will save you much grief, frustration, and likely your 
PA.

Thanks all for the speedy and helpful replies!  Wish I had run this by you 
BEFORE the contest rather than after.  I went back to the K3S and switched 
through various bands down to 160, and discovered for reasons unknown, on this 
band I had never used, the rig was set to “Ant 2.”  Since I am using a KPA 500 
and KAT 500, everything goes through Ant 1, and I had had no occasion to use 
the Ant switch on the K3 itself for quite a while.  Switched to Ant 1 on 160M, 
and the inverted L tunes quickly and easily.

As they say here in Massachusetts, you guys are “wicked awesome!’

Rich

Anyway, switch to Ant 1 for 160M has apparently solved the problem!

do anything special with the radio to make that work.


I do have a pretty good RF ground though.  Before I could get any decent performance 
on 80 (including decent SWR), I added to my RF grounding.  Where the HF coax enters 
the shack, the shield is pulled to ground (1' of #4 copper to an 8' copper clad 
ground rod).  That same grounding plate is also connected to another 8' ground rod 
about 15' away which is right below the service entrance to the house.  A piece of 
#4 connects from that ground rod to the electric meter base.  All of the #4 is 
buried except at connections where I've used Pentrox for CU/CU connections.  The 
ground rod at my HF coax entrance also is tied to 2" wide copper strap that 
runs into the shack to a copper bar (old -48vdc grounding bar from a phone switch) 
and all of my equipment is tied to that bar.  Under the shack where the copper strap 
comes in, the CATV coax and CAT 3 telephone wiring are grounded to that
strap.  The CATV coax has a little 4' ground rod right at the wall entrance 
that is tied to the electric meter base also.


This also cured some issues on 80 meters running an RF amp where I could make 
the phone ring and change channels on the TV when I keyed up!  All of that is 
fixed.

Subject: [Elecraft] K3S will not load or tune on 160 M

I put up my first 160 meter antenna last week in anticipation of participating 
in last weekend's contest.  I managed to get the antenna -- a slow slung 
inverted L with a single raised radial as a compromise on my tiny 100 by 100 
foot lot -- up in time.  I then managed to get the antenna down to an SWR of 2 
to 1 measured by a Rig Expert AA55 zoom analyzer, at the balun to which the 
raised wire and radial are directly attached, and ythen got the same 2.0 SWR 
reading at the shack end of a borrowed piece of about 50 feet of RG-213.  [I 
recognize that 2 to 1 is not perfect by any means, but it was certainly within 
the range of my Elecraft equipment, I thought.]

But then my K3S simply refused to tune or load into the antenna, either 
directly, using its internal ATU, or routed through my KPA-500 to a KAT-500 
tuner.  In both circumstances, the rig and/or tuner showed an SWR around 25 to 
1, and tuned at best to around 16 to 1, resulting in no apparent RF output.
After trying to fix this in various ways, I gave up on the 160M contest and 
turned to other pursuits, while seeking advice from several Elecraft-loving, 
160M-using, friends.

It finally dawned on me this morning to connect the rig to my dummy load.  The 
result of attempting to tune and load the dummy load is exactly the same as it 
was trying to use the new inverted-L:  initial 25 to 1 SWR, tunes down only to 
16.9 to 1.
The rig, amp, internal and external tuners, and dummy load work fine on 80M 
through 6M.  This is my first time trying them all on 160M.
QUESTION:  Are there special configuration or other steps I need to take to 
operate the K3S on 160 meters?  Do these symptoms suggest any other problems 
that you can help solve?

Please advise, and thanks!

Re: [Elecraft] [K3] - Hum on SSB Transmissions

[Joe Rogers]

Hi Don,

You hit upon exactly what I did!!  When I last did on air checks, I had the 
Proset in the rear panel jack and had same hum as in front panel - which, as 
you pointed out, would indicate that the adapter was not the problem and the 
issue is in the Proset itself.

I am pretty much convinced it is in the Proset IC now.  I just cannot 
understand why after only about a year, I have this failure.  My prior Proset 
was 6 years old and no problem.  Anyway, I am talking to Heil and hope to get 
the whole issue sorted out.

If you are using the Front Panel adapter for the ProSet-Ic, try plugging the 
microphone into the MIC jack in the back of the K3 and changing the MIC SEL 
menu to the rear panel.
If the hum is not present, then you have a bad adapter instead of a bad mic.

Re: [Elecraft] [K3] - Hum on SSB Transmissions

[Joe Rogers]

Hi Dale,

Checked that out.  No effect on the position of the mike.

I have a feeling that it is a break in the shielding allowing the 60 Hz to get 
onto the audio.

Have visually checked the electret element – nothing obviously wrong.  As this 
is a relatively new Proset have contacted Heil.

Thanks for the suggestion.

Joe,

You might check to see if the amplitude of the hum changes as you alter the 
position of the microphone. If so, the magnetic field of a transformer from 
another piece of equipment in the shack (such as a linear power supply) may be 
coupling into your microphone.

It seemed like low frequency noise so I set the TX filters for 50 and 100 Hz 
from 0 to -16.  No change.

Changed TX Gate from 0 to 10.  No change.

Disconnected everything from the K3 - RS232 cable, the antennas, keys, and 
paddle.  All except power supply and the Mic.  No change.

Mic+Lin ON or OFF no change.

Curiously, if I put my hand on the rig, it seems to reduce the volume of the 
hum.

Recorded some audio with Proset on my PC and it seems clean - no noise 
detectable.

I wonder if any of you guys - all of you probably more technically savvy than I 
- can come up with any ideas to solve this problem.

Thanks in advance for any help you can give me.

Re: [Elecraft] KPA fans in digital modes

[Larry (K8UT)]

Eric,

If you'll pardon a little self-promotion, you might consider using 
FANticipator to control the fans in your KAP1500. It's free, runs local 
or remote, and will perform those speed-changing tasks automatically for 
you... including shutting the fans off completely when the amp returns 
to ambient temperatures.

I, too, use FAN2 for both the KPA500 and KPA1500 in digital modes.  
Both amps run considerably cooler and with less thermal variation.
It would be great if the PF1 or PF2 keys on the KPA1500 could be used 
to toggle into a preset FAN2 (or choose your poison) when pounding away 
on digital modes like MSK144 for meteor scatter on 6m.  I don't know if 
it would be possible to do something similar for one of the keys on the 
KPA500--perhaps the AUX band switch?  For both amps I switch back to 
FAN NOR for casual CW use.
For all of you out there with even a 3el beam and 100w on 6m, please 
try meteor scatter using MSK144--you can make contacts every day out to 
1500km or more, even without a clear horizon.  Schedules optional at 
the Ping Jockey website.  It's a blast!

into a preset FAN2 (or choose your poison) when pounding away on digital modes 
like MSK144 for meteor scatter on 6m.  I don't know if it would be possible to 
do something similar for one of the keys on the KPA500--perhaps the AUX band 
switch?  For both amps I switch back to FAN NOR for casual CW use.
For all of you out there with even a 3el beam and 100w on 6m, please try meteor 
scatter using MSK144--you can make contacts every day out to 1500km or more, 
even without a clear horizon.  Schedules optional at the Ping Jockey website.  
It's a blast!
