I built a new Windows 7 64 bit Pro PC, got all my ham software up and running
and for a brief period of time life was good. A bad RAM module brought that
to a crashing (literally) end. Trying to recover from that I've been having
a series of problems that keep pointing to what looks like the well

That ended as a solution to problems long before Windows 98 came out.
Re-installing is generally a colossal waste of time and rarely solves
anything.
What to do instead?
Look in control panel and see what
Win 7 may find the drivers on it's own. I'd try that first. Elecraft changed
the KUSB
they sell from a Prolific to a FTDI chipset circa July 2010. Both drivers are
on the
site, so if you download them, it's important to know which cable you have.
APF was discussed extensively in August 2009 (check the archives) including a
simulation of the exact FT-1000D APF analog circuit which I found and sent
to Al W6LX. Here's Al's simulation which was the model for the K3's DSP
implementation of APF:

I have two K2/10 and a K/3. I would like to sell one of my K/2. The one for
sale has the following options: KSB2, KNB2, KAT2, K160RX, KIO2, KAF2 as well
as the Elecraft USB cable for computer control. It basically has everything
but the battery pack and 5 meter module, which my other K2 has. The

Excellent plot, thanks !
This really shows why we need to tune slowly !

I have a K1 that I built about one year ago.
I am very happy with it and it works FB.
However, I have this quirky thing when trying to set the power output.
I feel the problem is all mine ... but, I can't figure out how to correct it.
When I press the wpm + and wpm - buttons together I can set my

How are you reducing the power? With the WPM- button is my guess.
Set the menu OUT parameter to the power you want and it should stay.

Slightly off the subject (Blue Tooth), but I wear Phonak Savia OTE
hearing aids and they have a high-fidelity program selection. This
is for flat freq. response up to 22-KHz for music and television
listening. I definitely can tell the improvement even with 30dB
hearing degradation and loss
Unfortunately, one can't bump up audio output in FSK-D. I use a modem
which only can use 2 KHz tones. The drop in perceived audio level is
quite high there for me. Even if low tones were used, there would still
be a significant loss.
What say Elecraft? Why not let us bump up one segment?
Hamfest season is upon us. We are looking forward to attending more
Hamfests than ever this year!
However, we cannot make them all ourselves so we are asking for
enthusiasts to help.
A great group of enthusiasts is once again showing a table of their
Elecraft products at Frostfest in Virgina
Several years ago I purchased the KeySpan USB/Serial adapter. I have had
absolutely no problem with it on WinXP, WinVista and Win7 (both 3264 bit).
If you are using a laptop or change equipment around it is a must. The
driver can be setup so that the individual converter will always have the
I will volunteer for this, but I don't want to man the table myself.
I am looking for others around the Raleigh, NC area to assist, and show
off your Elecraft gear. I will have my K2 and K3 and a few mini-kits.
Let me know if you are willing to help me out here.

Good evening, I tried about a month ago to get the K3 working with WSPR and was
not successful at all. I wanted to give it a go and get it going this weekend
but instead of getting frustrated I wanted to tap in on the knowledge of this
reflector.
Here is what I have...

and planning to attend that could bring a KX1, K1, K2, or K3 to
Sometimes with my K3 I find it useful when operating split to do so without

frequency periodically. This is easy with the REV button. The problem is that

Hi Don:
I replied separately to Lisa from the email she sent out, but figured I'd
also write to you as I imagine you will be heading up this effort.
My K3 is now complete and I'd be happy to man the booth with you, bringing
my K3 and the few mini-kits I have from Elecraft.
