has the k2 a future?

[Michael van Hauten]

Dear elecraft -team,
during the last 2 years all new modules and software updates had been designed for the K3. Is the K2 out of the focus or is there a chance for all the K2 users to get new modules and upgrades in the future ?

The K2 is a very mature product, and I don't anticipate adding further  
internal modules to it. I've thought about a Li-Ion battery as a  
replacement for the present gel-cell, but it's still too expensive and  
is thus left as an exercise for the reader.

The P3 should work with the K2, though less tightly integrated than  
with the K3. If that pans out, we'll post details later.

We have no plans to phase out the K2, which is still going strong  
after 10 years (for which we thank our customers!).

The K2 fills a unique role, and it's the only full function transceiver you can build from through hole components (its only rival is the JUMA TRX2 from Finland which is made with SMT and it is more money for less functionality.)

Although you don't anticipate adding more modules to it there might be a demand for an official version of the last digital interface board that was designed by the late Pauli Nunez EA3BLQ. Since a Li-Ion battery option isn't on the cards I suppose I'd better start thinking about replacing my old gel-cell - 10 years old and still holding a charge. Is this a record?

[wrmoore]

Wayne, any hope of firmware updates for the K2?  My favorite would be keeping mode and ATU setting per VFO.  I'd be willing to purchase a more expensive microprocessor IC if more memory is required, as I suspect it is.

And a good thing. This past weekend two of us went to a undisclosed location in the
Sierras to check out our FD QTH for next year. Although I wouldn't give up my K3 for
anything, there is no comparison to the K2 for this application.

The combination of QRP-configured K2 plus Asus netbook was tested last year in a
not-so-great location, but we ran the whole period on batteries and solar panel. The K2 is
by far the winner if you are looking for high performance with low power consumption.

By the way, the secret location is a killer. With 15 watts to a 40 meter loop with apex at
30', our first QSO was a 5N (Nigeria). That's on 40 meters at 4 PM local time! And our
antennas are going to be much, much better.

G'day,

I understand from a previous post that memory is maxed out.  Also
that a possible pin compatible micro with more memory is a
possibility.  I have offered the idea that pruning the rather
generous CW memories might offer up enough memory with the existing
micro for the update you mention.  A functionality which has been
requested for years now.

Regards,

Mike VP8NO

Yes, I'd be in for one of these.  Perhaps Elecraft could produce and  
sell them, donating a portion of the profit to Pauli's family or a  
charity of their choice....?

Hello Wayne,

Yes, K2 is still my favourite field day and QRP rig and no others can bit it.

I now have 3 x 3.7v 3300mAH Li-Po cells in the KBT2 and they work very well.

Hi Wayne,

Assuming that you had nothing else to do (!!), a Mk II version of the K2
using a different and higher IF than the presently used 4.914 MHz IF might
be worth considering if it is a viable commercial proposition.

The benefits gained of course would include a reduction in the number of
"troublesome" receiver spurious responses, many of which are responsible for
the many birdies found in the K2, and a reduction in the number of  close-in
and crossover transmitter spurs.

I have been tempted to make this change and other RF/ IF circuit changes to
my K2, also add some minimal shielding on the RF board which need not be
expensive nor heavy.

Hi Geoff

I would think that the phase noise limitations of the K2's design would limit its appeal.

I would be more interested in a K3-Junior

Maybe this K3 junior would have a single receiver
Inbuilt power supply
200 watts 50 volt or higher fets
Layout like Yaesu FT950
VFD display - blue
external TXCO input
A real analog S-meter
Front firing speaker
A big 10 watt audio PA
Amplifier tuning pulser(audio)
2 tone generator  controls on the front panel
Built in directional coupler for TX monitoring
Optional control port for a DSP receiver like QS1R(or even a Elecraft version of the QSR1)
A high performance tuner like the SGC230
SO2R interface built in for 2 X K3 JNR's
USB interface
Ability to  select and key  2 amplifiers with different drive power levels
In built dummy load
NTIA specifications for the TX
PA that can work into a 3:1 VSWR load
Blue tooth headset support

Anyway its a nice dream,  however this radio would be the best selling radio in the world I would think. It would certainly make the new Hilberling look like  very poor value for money

I would buy 2 or even 4!


John

Hi Bill

Yes it will be manufactured by Telefunken, it was the talk of the town at Friedrichshafen 2009.

Telefunken Racoms will be producing the Hilberling transceiver.
Its splattered all over web.

I´m still very happy with my K2 and when I bought the K3 I thought, that I´d have to sell one of my other rigs.In fact, I don´t want to sell one of them and I´ll certainly keep the K2. If the NB  is redesigned, this rig will almost be perfect for my needs.(the K3 and IC 761 have got much better noise blankers!)

73, Chris-OE5CSP

[Arie Kleingeld PA3A-2]

Any transceiver can be improved. But working on the K2 again...
Elecraft would have to make a business case first and then decide.


Anyway, my K2 is just fine as it is, and it's on duty for the next few weeks
as one of the transceivers in the TY1MS dx-pedition.

I already worked them with my K3  :-)

[Johnny Siu]

Hello Julian,

Yes, I agree with you.  Elecraft is very clever in segment the market to suit different market demand.

Although I do not always clap my hands for K3, K2 is definitely the best choice for portable use.  Upon replacing the Lead acid battery in the KBT2 with Li-Po cells, the K2 is now very light weight and can be operated for loooong time.  It is the greatest portable rig when compared with the others.

In the past, I asked whether K2 was good for ARES.  Now, I would say that it is good for QRP ARES operation.  Just throw up a piece of wire of about 30 feet and press the tune bottom and let the KAT2 tune.  After that, you are on air.  Trouble free and no headache.  Just Excellent.

I am not certain where that statement about phase noise comes from, nor
if it is valid.  The K2 comes in at -123 dBc (or -124 dBc) in the phase
noise category.
The transceiver comparison list at the Elecraft website does list phase
noise as measured by ARRL and by Sherwood.
I did a quick count -
There are only 5 listings that have phase noise measurements better than
the K2 (one was the K3), and 19 ranked worse than the K2.

I don't have phase noise measurement capability here, so I must depend
on the ARRL and Sherwood test data, but those measurements are well
respected by most hams.

The Sherwood list is more extensive, and lists "LO noise".  In the 27
transceivers at the top of the list, there were 16 better than the K2, 3
equal to it, and 8 listed worse - so IMHO, the K2 is a bit below average
within the top 27 listings - not too shabby for a 10+ year old design.

I liked the lead acid battery because it made the K2 feel solid and not move about on the desk, when it was my main rig. Now I have the K3, it is really only a portable and backup rig, so perhaps Li-Pos would be a better option. But I don't know what to do about charging. I made a PSU for my 10W K2 in an EC2 case, and adjusted it to deliver 14.2V output, and it has done a good job of keeping the gel-cell battery charged all these years. Presumably Li-Pos would need a more complicated arrangement.

[Johnny Siu]

Hello Julian,

Charging Li-Po cells is a little bit different but not difficult.  I use a multifunction intelligent charger bought from Radio Control players (only US$50 locally).  I need to modify a bit on the charging circuity.  Don's webpage gives a very good idea in how to do that.

The total cost of 3 x 3.7v 3300mAH Li-po cells is only US$30.  Standby current of K2 is around 200ma.  Therefore, K2 can be operated for a long time even at its rated power of 15 w.

cheers,

Johnny VR2XMC

I liked the lead acid battery because it made the K2 feel solid and not move
about on the desk, when it was my main rig. Now I have the K3, it is really
only a portable and backup rig, so perhaps Li-Pos would be a better option.
But I don't know what to do about charging. I made a PSU for my 10W K2 in an
EC2 case, and adjusted it to deliver 14.2V output, and it has done a good
job of keeping the gel-cell battery charged all these years. Presumably
Li-Pos would need a more complicated arrangement.

It will be the flash program memory that is maxed out, but the CW
memories will be in EEPROM, probably the off-chip serial EEPROMs.
