Hello All,
I'm happy to announce to the list that K2 Basic Kit #4068 is up and
running @ f8bxi.
I bought it back last June and had a lot of troubles only due to myself
and mistakes I made due to lack of experience :
- 1 missing solder on U6 Control Board (stressful but fun to solve)
- 1 J310
Bob,
The cheapest GPS receiver I ever bought costs $100 compared to the $25
for the WWV clock. That was a couple of years ago, and the cost of both
has come down. That's the why.

I was wondering if anyone has evaluated the K2 receiver performance numbers
with the KSB2 as the principle IF filter instead of the onboard filter
adjusted to 500Hz bandwidth? I expect the 5Khz BDR and IMD DR3 might suffer
somewhat, but has anyone actually played with this?

Several years ago I had the opportunity to visit the WWVH site on
Kaua'i. I drove into the site, found the office, went in and there was
NO ONE there. Oh, well...I signed the visitor log and scanned through
it, noticing the large number of hams who had visited. I even recognized
some of the calls.

For some digital modes, you have to know the time to the second or close to it,
as some digital sequences are 15 or 30 seconds long. Even for typical SHF
terrestrial work, the common adage is You call on the odd, I call on the
even. There are 60 and 30 second sequences on that too I believe.
Well, there are times when you need fairly accurate time. When
tracking satellites across the sky for the digital modes, or the weather
sats. Your tracking software has to be pretty close to the correct time to
keep up with the position of the satellites. I have a controller that moves

Probably, unless one is using some very exotic mode such as Coherent CW,
millisecond synchronization is not actually required for ham operations.
However, there are some fairly routine operations in which sub-second
resolution is a necessity and not a luxury. These include the
I've just started building my K2, and although it's not my first kit, I have
only built a couple smaller kits. I have a couple newbie questions, that I'd
rather not burden Elecraft with directly (unless necessary). These questions
came up during my parts inventory of the RF board.

A few people have written with questions. Here are a couple more photos.

Yep. Several ops mentioned modes I don't use G.
I often use the propagation beacons at 20 meters and down, but my PC clock
is synched to NIS through the internet connection, so it's always dead on
for that purpose.
Is it okay if I buy an atomic clock some day for the 'Gee Whiz' factor G?

Yep.
And, if anyone wants, I will send them a picture I took of two
identical model atomic clocks, both showing that they are locked
and showing different times (nothing doctored in the picture, time

Hello All,
Anyone using the Idiom Press SCAF-1 audio filter with their K2 and/ or
older tube receivers? How does it compare with DSP audio filters. 99%
of my operating is CW so SSB is not that important to me. I would like
to hear your comments and experiences.

Hello, Dan. Check out: http://www.neonnixie.com/ , the site of a friend of a
friend.
You have good taste. Nixies look totally cool. Much better that 7-segment
displays. Just look at a Nixie 9. It's got so much beauty and
I use it and like it. I find the SCAF-1 complements the capabilities of the
DSP in my K2.
