Right on. That's how USB connectivity was incorporated into our latest
product line. The FTDI part interfaces with a UART on the
microcontroller on one side, and a normal USB host port on the PC.
FTDI furnishes a USB driver and an application level DLL which our PC
hosted control software calls in

It seems to me the glaring error with Elecraft's serial port
implementation is the ability to blow the I/O card out of the water
if you use anything but the "special" K2 serial cable. They should
have designed it so you could use an "off the shelf" serial cable.
Way too much damage exposure. Re

I have a very nice well-built Henry Radio 100B solid state amplifier.
Like the KPA100 it uses a pair of 2sc2879's to produce 100 watts. It
has a heat sink and fan that looks like it would be enough for a KW!
Unfortunately, it doesn't have built in LP filters so it can't be used

whatever. Why did they try to fix what wasn't broken?

Hi all, first post to the reflector. Don't have any Elecraft gear... yet! First
piece I'm considering is the XV50 transverter, and I'm wondering if the power
output can be coaxed up to 27 watts -- what I need to drive my TE Systems 0552G

Howdy Folks,
We had two very good nets this evening. Twenty meters had QSB from
East to West and it was a little light to me. Forty meters had it all:
QRM from the Flying Pigs, QRN from a storm somewhere in the Midwest, and
QSB would come and go throughout the net. Made life interestin
Actually, I'm working on a USB interface for the K2. My prototype worked
quite well. It only received but what I saw on the waterfall looked good.
The part of the design I was most concerned about (USB) worked well. It's a
compound USB device - hub with soundcard and serial port. I'm in the process
Most small-volume projects I've seen just use the FTDI USB to serial
interface. Basically it moves the USB-to-serial interface into the
project.
Not real sure if it's hard to use, but check out the WinKey USB to see
an example. I also have a PIC programmer that uses the same chip. The

was a rumor I had heard at a software conference then.

In general that's a misnomer. They're correctly and commonly called "lag

are a large wood screw. Like so many things in the English language, there

I think that those asking the question do not fully understand all the
facts.
Admittedly, all computing hardware that comes with USB and RS-232 hardware
comes with drivers for this hardware. However, USB is treated as another
bus, like PCI, and drivers must be installed for each kind of hardware
What a great Father's Day. Thanks to Don and Gary and countless
others, my errors have been corrected and I'm on the air with K2
