In am going to buy the K3. I LOVE QRP and SIX METERS. I also like to
buy American Made items. The K3 seems as though it was designed for
ME. I like the fact that get e-mails from this group from the dudes
that designed the thing AND they speak fluent English. Can
t get any better than that!!

Paul, this looks like a good idea and the products certainly look like they
will be useful. Could you recommend any particular item on this site - the
spray?
The pens?
Would normal and gold be useful or is just one type sufficient
Any comment would be helpful since I'll buy a few things, taking advantage
of one postage cost and the current exchange rate.

I like the little bottle of ProGold with the brush in the cap, for wiping pins in connectors.

I also like the felt tip (chisel tip) pen for wiping flat contacts on PC Boards.

For large quanties of PC Boards, of course you'd use their ProGold cloths.

I have spray bottles, but they get the ProGold everywhere so I don't use them too much.

Also get some DeoxIT for unplated connectors.

I also like their Moving Contact Lubricant for getting rid of the scratchiness in pots.

Thanks for the suggestion Paul.  Actually I do use ProGold on all plated connectors.

I think we were aware that this was likely to happen...
and, in spite of my earlier "grousing"... I am more than willing to
wait a while longer while the K3 is tweaked and furtehr refined.

Hat's off to Wayne and Eric.. the rest of the gang AND, of course,
the Beta testers...

News of the slip in the time line really is appreciate, Thanks for
keeping us up-to-date with the latest developments.

Like my grandfather used to say... "The best things in life are worth

I agree with you, its an excellent result for the K3. I would rather
own and operate a radio where the K3 sits on the performance table,
rather than have something as poor as a FT2000 thinking that it is
superior regardless of what the numbers say.
Craig you prompted me to go read the FT-2000 list. I had not seen Rob
Sherwood's recent measurements. Here are the key results for anyone
who has not seen them yet (not yet on his website but will be added soon):

Dynamic Range 20 kHz 6k roofing 90 dB
Dynamic Range 20 kHz 3k roofing 81 dB
Dynamic Range 2 kHz 6k roofing 61 dB
Dynamic Range 2 kHz 3k roofing 63 dB

Blocking above noise floor at 100 kHz spacing, AGC On 120 dB

Phase noise (normalized) at 10 kHz spacing: 122 dBc

Noise floor, SSB bandwidth 14 MHz, Preamp Off -117 dBm
Noise floor, SSB bandwidth 14 MHz, Preamp 1 On -124 dBm
Noise floor, SSB bandwidth 14 MHz, Preamp 2 On -134 dBm

These results are generally consistent with previous measurements by
Inrad (W2VJN) and ARRL. There is surely some serious arm-waving going
on trying to justify why these results are "superior regardless of
what the numbers say"! :-) What a hoot to read.

Bob, I've seen two different comments on phase noise. One said it was
at least 10 dB better and the other said something like 15-20 dB
better. Someone asked if that was -140 dBC and whichever person
responded (don't remember if Eric or Wayne or KI6WX) said they did not
want to be pinned down at this time. KI6WX apparently designed the
synthesizer and I believe he is the one who said it was at least 10 dB
better than the K2. You might search phase noise on the main Elecraft
reflector and find the actual comments, but I believe we will be
pleasantly surprised.

The IMD Dynamic range number is fantastic. If like the Orion the IMD
dynamic range does not change much at 2khz then theres little doubt
that the K3 will be the best performing radio on the market.
Actually, Wayne mentioned
(http://mailman.qth.net/pipermail/elecraft/2007-July/071030.html) a
10dB falloff in IMD from 5Khz to 2Khz, which would bring it in about
the same as the Orion I/II at 2Khz.

K3 IRC

Thom LaCosta <lacosta@...>
 

I've created an IRC channel for K3 folks....one of the plusses is that you don't need an IRC client to access it. There's a web based access at

http://www.zerobeat.net/qrp/k3chat.html

if you do have an irc client, you can reach the channel at

irc.icq.com - /join #k3

IRC is a lot like the bands...if no one is logged on, there is no activity. Unlike radio, if someone is there, you'll see them.

Interesting - IMD3 dynamic range - The filter used in the Orion is not
stated (or I didn't see it).
Simon, ARRL always measures IMD3 with any 500 Hz optional filters
installed. For some reason, either due to measurement technique or
equipment differences, Ten-Tec's IMD3 specs for both Orion and Orion
II have always been optimistic by 6 to 8 dB. IMD3 performance at 2
kHz is typically 92 dB for Orion and 95 dB for Orion II, as measured
by ARRL, Sherwood Engineering, RSGB (G3SJX in Radcom Magazine) and
W8JI. Elecraft may have the same problem but we won't know until one
of the independent testers posts some results.
