K4 Update: Transmit Features -- Emphasis on SSB

 

As Eric alluded to, the entire Elecraft design team is safely working from home. We're busy adding new capabilities to the K4 and testing it in real-world conditions. (If it weren't for the lock-down, I and other early users would still be inviting operators over to try it. Previous demonstrations have led to amazement over the sound of the receive audio quality, among other reactions.)

With its new, faster DSP, versatile architecture, large display, and essentially unlimited code space, the K4 can offer features that go far beyond what we've been able to offer before.

Here's a sampling of what this will mean for SSB users:

*** Optimal audio

The K4's RX and TX passband in SSB modes can be configured to be flat from below 50 Hz to over 4 kHz, with none of the drawbacks of crystal filters (delay, ripple, passband edge effects). Easy to use graphic TX/RX EQ and other bandwidth controls allow the operator to tailor the response per-mode and for different microphones. The overall effect is full, rich audio in both transmit and receive -- the latter in full stereo.

Wider transmit and receive bandwidths can also be configured for digital audio modes, ESSB, and AM, at the operator's discretion.

*** Exceptional ALC performance

The K4 uses a new ALC system designed to completely eliminate power overshoot and varying loop dynamics. This makes it both easier to adjust and more compatible with external amplifiers.

*** Multi-parameter transmit metering

In voice modes, the K4 provides clear bar graph displays of all four transmit parameters simultaneously: power output, SWR, ALC, and compression (processing level). Real-time numeric readouts of power, SWR, supply voltage/current, and PA temperature are also available.

*** Foolproof split transmit indication

You'll never lose track of whether you're in SPLIT mode with the K4: all four transmit bar graphs are grouped either on the left (non-split, i.e. VFO A = TX) or right (split, VFO B = TX). TX icons are also clear and unambiguous.

The K4 also allows full cross-band/cross-mode operation in both split and non-split.

*** Versatile audio I/O

There are mic and headphone jacks on both the front and rear panels. Some operators prefer to use the rear panel connections to avoid cluttering the operating position. Audio for both voice and data modes can be either analog (LINE in/out) or digital (via USB or Ethernet).

*** Large DVR memory

The digital voice recorder draws on the K4's large pool of flash memory, allowing virtually unlimited expansion for both transmit and receive purposes. There are also new, easy to use playback controls.

*** Redesigned PA stages

All transmit stages have been upgraded, with improved biasing, parametric monitoring, and T/R sequencing. Hardware is also in place to support closed-loop amplifier IMD optimization, both internally and externally.

*** Support for future operating modes

With DSP and MCU horsepower to burn, we'll be able to add new voice and data modes in the future (and even new bands). The K4 is designed from the ground up for extensibility in both hardware and software.

Latest K3 utility doesn't play well with Catalina

g4abx
 

Evening all from the UK
Tried to upgrade my K3 with the latest firmware using my MAC and the new 64bit utility.
K3 'froze' at LD.
Any number of power off and re-starts didn't work.

Fortunately I had a Win 10 desktop with a direct Rs232 port.

I eventually managed to get firmware to load using the Win 10 machine.
I shan't be using the MAC utility any time soon!

Fixed.
Turned out to be two faults.
Replaced D5 (BAP64-04), and RXA modification board, for second time , and unit now works perfectly.

Test

 

Sorry for the bandwidth

Hope to be of some service.

Faulty KXV3-1

JohnG3PQA
 

Am trying to fix an old 2008 KXV3-1 Rev.B which has the following symptoms:-
1. When using the RX input, pressing the RX button does not disconnect the signal
2. The RX sensitivity is approx 10dB down on both ANT1 and RX inputs.
I can hear relays operating when pressing the RX button.
I have replaced both D5 KXV3 and D25 on RF board, with no change to the symptoms.
Has anyone seen this before?   Suggestions welcome.

Re: PF1

Kelly Breed
 

Ha! Fair enough.

Yes, it can be done. Sort of. I haven’t figured out a way to bounce between fine and coarse, but you can bounce back and forth from 10Hz to coarse easily. You’ll need the K3 utility to program your K3 with a macro. If you’re interested the steps are as follows:

1. In the K3 utility create a macro with the following macro command: STH49;  Don’t forget the semicolon.
2. Click the “Write to K3” button
3. Click save.
4. On your K3 navigate to the CONFIG:MACRO menu and then press the numbered button on your K3 that matches the number of the macro you created on the computer. For instance, my macro was the 4th one down in the menu so I pressed 4.
5. Press and hold the PF1 button until it says “PF1 set”

You can look at the programmers reference for more macro suggestions or ask again here!

Re: K3 ERR TXF on 6m FM with 12 kHz filter

John V
 

Keith/Joe, thanks a bunch.  I reread everything that I read yesterday and indeed it is written 13-13-13-13 EVERYWHERE.  For some reason I was “seeing” 12-12-12-12 in the manuals  and it became some sort of pretzel logic.  The original filter setting number that was shown on my K3 utility was set at 12 kHz so maybe that got me headed  into the pretzel store.  

 

Woohoo, I changed the setting from 12 to 13 and now I can hit a 6m repeater that is about 60 miles away with just 100 mw.  

 

Thanks again, John NA6L San Diego CA USA

GUIDELINES

Amateur Radio operators are requested to adapt to the Coronavirus mitigation guidelines as they apply to amateur radio operating.

All ham radio operators are encouraged to stay at least 6 feet from the microphone in order to maintain proper separation from others.  The distance may be reduced if a mask is put on the microphone.
 
CW operators should wear appropriate gloves when handling keys.
 
There should be no more than 10 stations on the same frequency at the same time.
 
Disinfect your knobs, switches, etc before operating ... especially touch screens and PTT.  Shoe covers should be worn when using foot switches.  Use of hands-free VOX is strongly encouraged although from 6 feet away, it will be necessary to shout.
 
Disinfect all antenna cables coming into the station.
 
Only mobile stations and walkie-talkie contacts are permitted where sit-down service has been banned.   The 6 ft microphone separation guideline is suspended for these types of operation, but a mask on the microphone is strongly recommended.
 
Mobile operators are encouraged to remain in their vehicles except to get necessities.
 
Operators should leave their operating positions only for necessities.
 
Outdoor antenna work is allowed as long as there is social distancing among all who are present.
 
Hoarding of batteries, spare tubes, etc. is discouraged and is unfair to others.  We are in this together.
 
New equipment and parts should be ordered  online for front porch delivery.
 
Do not test (tune) your equipment unnecessarily.   Testing should be reserved for those who actually need it.
 
Your understanding and cooperation in this matter will be appreciated.

I know the +/-1 ppm parts are available from Hong Kong, but I don't want to wait that long.
