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

Administrator

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 the speaker from triggering VOX.

*** TX GATE (Transmit Noise Gate) ***

This feature is useful if you're operating in a very noisy environment. By adjusting the threshold (TX GATE menu entry), you can automatically cut transmit audio off when you're not speaking; that is, wind noise or other environmental sounds won't be heard at the receiving end.

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....

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

In reply to this post by wayne burdick

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!

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: SSB Features of the KX2 & KX3 You May Have Overlooked...

In reply to this post by Jim Brown-10

Hello everybody, I have found that at least in my KX three the equalizer settings appear to be negated when I turn compression on. Even if I set them really strangely with compression off, it goes back to whatever it was when I turn compression on. So I guess what I’m trying to say is no matter what I do with the equalizer, compression seems to negate it.

I think I might have the long build record. I bought the kit in about 1999 and started the build. I stopped after about 30% building while an addition to the house was going on with a move of the ham shack. I kept abreast of the various mods and ordered new firmware twice, ordered toroids from the toroid guy, and finished the build in about 2010. One of the firmware chips never got used. After all the delay and doing the mods without having to undo any thing, it worked fine when I powered it up and aligned it.

So I would say about 10 years give or take a month.

> Subject: [KX3] SSB Features of the KX2 & KX3 You May Have Overlooked...
>
>
> 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 the speaker from triggering VOX.
>
> *** TX GATE (Transmit Noise Gate) ***
>
> This feature is useful if you're operating in a very noisy environment. By adjusting the threshold (TX GATE menu entry), you can automatically cut transmit audio off when you're not speaking; that is, wind noise or other environmental sounds won't be heard at the receiving end.

It took me several practice runs, but I was building a basic K2 in about
20 hours for a while.

As familiar as I am now with the K2, I cannot repeat that due to 'shaky
hands' that have come on with aging.

Settings in KX2, KX3, K3, and K3S are all saved automatically when you
turn the radio off (but NOT when it loses power). When these radios lose
power, they revert to the last saved settings when turned back on.

Many settings for these rigs are saved by band, but since Wayne spends
some of his available spare time tweaking the firmware to add features
like that for more functions and more sets of operating conditions, you
need to keep up the the changes when you load firmware updates, and/or
study the Menu settings section of the latest version of the manual.

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

Folks,

One thing has become abundantly clear - the Firmware Release Notes are
an extension of the manual. Pay attention to them.
If you do not know where to find any but the latest, look in the
K3/KX3/KX2 Utility Help files - there is a complete list there.

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

In reply to this post by wayne burdick

The autonotch is one feature that I have not found to be all that useful
with my K3. After this message from Wayne I decided to try it again and
find it is better than I last remembered. However, on 75/160m where
signals are usually quite strong there is a considerable amount of
distortion on the received SSB audio when using the autonotch. On these
bands I always have the preamp off and attenuator on plus the RF Gain is
dialed back to about the two o'clock position on these two bands.

If I must get rid of a carrier such as from a group of AM ops 2 kHz
away, I'll mostly simply adjust the Hi-cut down to 2.05 kHz which
usually cuts off enough of the carrier to where it is not objectionable.
Otherwise I must use the manual notch and possibly chase carriers from
the round table of boat anchors that don't land on exactly 1945 kHz when
I am on 1947 kHz.

The distortion effect is along the lines of the autonotch aggressively
searching for carriers to notch and it trying to suppress voice peaks.
Perhaps the algorithm could be tweaked to lengthen the time the
autonotch uses to determine a sine wave carrier as opposed to a voice
peak.

Don makes an excellent point regarding new firmware release notes. Unlike
other manufacturers, Elecraft manuals in PDF allow us to make notes with
Acrobat Reader. If pertinent, I update my manuals with release notes. That
reinforces the changes, even if briefly. However, when I look in the manual
for a specific function, I will likely see the note with the most current
information.

RTFM is a popular acronym today. It also implies the "M" (manual) is
current. It's our, IMHO, responsibiliy to keep our manuals current. We can
even add our own notes, like lessons learned. Once updated, I save mine by
adding "Annotated" to the original filename. I also keep copies on any
computer I might use with the gear, especially ones I take on-the-road.

As to firmware updates, when doing a firmware update, also print out the
release notes and insert them into your manual. Now, you have an
updated manual.

Dear OMs,
It is also possible to print on one side of the page and keep the back
facing page for updates.

I keep pinching myself with the service Elecraft gives us. This may
be found with Flex but how many other manufacturers allow us to communicate
with the companies engineers and provide improvements to their products on
such an ongoing basis.

Keep your electronic manual copies on Dropbox. That way you only have
one copy, but it appears on all your PCs and devices.

Thanks, Wayne, for the pointers. There were a couple in there I had
actually overlooked in my KX2. I'm a long-time user of the K3/K3s, and
I just learned recently how to set up the memories to use them as band
selectors.

I'm currently surprised and pleased to discover new things about my
Elecraft gear. You do indeed, 'delight the user'.
