[Elecraft] K3 Preliminary Specifications

[wayne burdick]

On our K3 page, you'll now find a link to a .pdf version of the K3's 
preliminary specs. We'll add an HTML version, too, probably next week. 
Any of these specs may change pending further testing or design 
changes.

PLEASE don't call or e-mail with questions about the specs. We'll add 
or update specs as time permits. Discussion about the specs is fine, of 
course and we'll be diligently reading the reflector. But I'd like to 
ask in advance that any *arguments* about specs be taken off-line, so 
Eric (our reflector cop) doesn't have to put the hammer down  :)

Comment about RX specs:

Receive dynamic range (IMDDR3) is shown for 5 to 20 kHz offsets at 
present, with the 400-Hz INRAD filter. We're trying to be conservative, 
because testing organizations may get slightly different results due to 
variations in equipment and procedures. Our own tests, conducted at 
three separate locations, consistently show 102 to 105 dB at 5 kHz. We 
also didn't list 2 kHz offset performance yet, because we're carefully 
characterizing all filters. Typically, we're seeing low to mid 90's on 
all filters. (Measuring the K3's dynamic range has been a challenge 
because it's higher than anything we've dealt with before. We've had to 
beef up our test gear to handle it.)

Again, please, NO phone calls or e-mails about specs -- this will just 
slow down the engineering and support staff. We're dealing with many 
details right about now, as you can imagine.

Thanks!

73,
