What? Are you dreaming? That Kenwood radio will never be the son of our K3's.

In reply to this post by jack jackson
I talked to a Kenwood rep at Dayton this morning. He said the TS-590 would have the best receiver specs out there. I asked if it would beat the K3 and he said the TS-590 would have the best receiver specs out there. The radio has an IF of 11MHz and two stock roofing filters - 2.8KHz and 500Hz - no spare slots and no options. It will not have a second receiver or option for one. I remarked on it's superficial similarity to the K3 and he said that the K3 had done some things right and that they were not too proud to use them. Price is expected to be $1800 and expected to be available in the fall. The model on display was an operational hand-built prototype with some features disabled.

As a very happy K3 owner, if Kenwood can meet or slightly exceed the K3 receiver numbers with this radio then more power to them. It still won't match the overall capability of the K3 and Kenwood certainly won't match the Elecraft level of support. It might, however, attract users who are looking for a radio with good specs at a mid-level price and without the complications (or availability) of options.

Re: Son of K3??

Geoffrey Mackenzie-Kennedy
If the TS-590 uses only two roofing filters and has "the best receiver specs
out there", then I speculate that it could be using an H-Mode mixer, that
the roofers exhibit better than average in-passband and skirt IIP3 followed
by a decent "strong" IF, plus a LO whose phase noise is suitably low
e.g. -145 dbc/Hz at 1 kHz offset.

If they have gone down this route and if they have paid attention to
important details such as core sizes and mix, then with the 500 Hz roofer in
line we might be seeing spurious free IMDDR3 figures of 120db at spacings of
1kHz, and a HF noise figure of 9-10db without a preamp, based on actual
measurements made on a living "H-Mode" receiver.

Re: Son of K3?? & P3 keyboard interface

In reply to this post by Gary Gregory

Hi Gary:

Here is my take on Dayton 2010..

The Elecraft booth was by far the most popular place to be. Saw the new
P3 and the new KPA500. Both were impressive. No pictures from me. I had
enough to tote around..

  The new Kenwood radio was good to see but not a lot of interest by my
observation.

Yaesu's boot was full mostly of people looking for a free hat, myself
included ( just put it on the self with the other 6 or 7 I have).

Alpha showed there new 6 meter offering. Runs a 4CX1500 tube and will
delver lots of smoke on six. Not yet type accepted or priced but the
rumor was 5 to  6k.. OUCH..!!

The bone yard was much better this year over last. Much less plain
"junk", lots of land mobile "junk".. Lots more actual ham equipment.

My observation is that this Datyton was much better then last year. Had
lots of fun and met lots of great hams. By the end, both my feet and
legs were very mad at me..

Re: Son of K3??

Geoffrey Mackenzie-Kennedy
No criticism of Elecraft nor the K3 was intended, besides I do not have any
good hard data as to the receive signal handling capability of the K3's DSP
sub-system.

What triggered my comment was that the TS-590 is said to use only two
roofing filters and it is claimed by the manufacturer that "it has the best
receiver specs out there". If it is a superhet, this sounds suspiciously
like a receiver that uses a H-Mode mixer, high IIP3 roofers, and a "strong"
IF. The H-Mode is a type of mixer which appeared more than 15 years ago and
yields very good  "IMD" performance, better than most, and as far as I know
is not yet used in commercial amateur receivers - I don't know why not.

It will be interesting to see whether or not the designers of the TS-590
receiver have used a proper Gain Distribution analysis to obtain optimum
IMDDR3 performance, which should include every "stage" or element in or
which impacts on the signal path, this includes L-C filters, crystal filters
as well as LO phase noise. It will also be interesting to see their approach
to the LO, because a PLL based synthesiser whose cost is within budget would
probably be too "noisy".

All should be evident from the schematic when and if it becomes available.

Had a chuckle while I read your reply.

myself...(Grin)

Well I better go pack the gear for this Dxpedition, man I have a heck of a
lot of "stuff" to put on the trailer and now only 36 hours away from
....lights, action, roll'em...

Elecraft up dates it's stuff and as you can see everyone on web is  
helpfully and cool. Even if just get the ten watt unit you love the K3
