K2 Control Cable Question

I have tapped into the K2's IF and am sending the resulting signal to a
Softrock. The output of the Softrock is fed to a CW Skimmer. The K2's
control cable is used by CW Skimmer to display the K2's current
frequency. The connection is bi-directional as the CW Skimmer can
command a change in the K2's frequency.

I am using MixW3 as my logging program. I would like to feed the
frequency info coming from the K2 to MixW as well. Is it possible to
accomplish this by tapping into the K2's cable and extracting the RXD
and GND signals to be sent to a different COM port that is used by MixW?
The OS (Win 7 Pro) won't allow both CW Skimmer and MixW to use the same
COM port.

Thanks and 72,

Jim - W4BQP

Re: K2 Control Cable Question

Jim,

I would rather suggest you look at LP-Bridge by Larry Phipps. It allows
multiple software applications to use the same com port.

Re: K2 Control Cable Question

No, LP-Bridge does not allow multiple applications to access the same
COM port .. it allows multiple applications to access the same *K3*,
by placing itself in the middle, and forming a "virtual K3", which
keeps itself in sync with the real K3, and provides access to
applications through virtual COM ports. It doesn't work for any rig
other than the K3 (AFAIK).

Re: K2 Control Cable Question

Wouldn't hurt to try it. The basic commands (freq mode etc.) are the same
between the K2 and K3. Since the K2 and K3 basics are Kenwood compatible,
I'd bet LP Bridge would handle a Kenwood nicely too.

Re: K2 Control Cable Question

In reply to this post by Iain MacDonnell - N6ML-2

I'm afraid Iain Is correct. I installed LP-Bridge and found that it's
input port is permanently set to 38400 bps whereas the K2 wants to play
at 4800.

LP-Bridge is the right idea. Are there any other programs similar to
LP-Bridge?

Thanks and 72,

Re: K2 Control Cable Question

Hi,

I have no idea if this works or is even still in development, but a
quick search for "virtual com port" led me to:

http://com0com.sourceforge.net/

which includes hub4com, a way to have multiple applications access a
single serial port.

I don't have a need for this just now, so I am not brave enough to try it,

OT: ICE still functioning?

In reply to this post by Ross Primrose N4RP

Wondering if anyone on the list has information on these folks. I
ordered some bandpass filters from them about 6 weeks ago and have
heard nothing from them. I have sent mulitple emails and rang their
phone twice. They do not respond to emails and do not answer their
phone. I do realize that the owner passed away suddenly about 4 weeks
ago. I'm wondering if they are still functioning or have closed up
shop. Does anyone know?

I've used Eterlogic VSPE for this sort of thing with a K3 (http://www.eterlogic.com/Products.VSPE.html). Don't see why it won't work with a K2. They do have a 64-bit version but unlike the 32-bit one it isn't free.

Re: OT: ICE still functioning?

Have any of you ICE customers emailed ICE to inquire?

Why would you think anybody on an Elecraft mailing list would have an
authoritative answer as to whether ICE is still in business, or whether
they received/processed your order or not?

One last time. http://www.iceradioproducts.com/
Read the announcement and if you have questions follow the instructions
at the bottom of the page.

It appears that I.C.E. may indeed be kaput. This morning the 800
number no longer works. Yesterday it rang but no answer, today you get
the recording that the number is 'temporarily unavailable'. Dunno how
long 'temporary' might be.

Looks like there might be an opening here for Elecraft to start
producing bandpass filter kits . . .

There are three designs of bandpass filters for the ham bands. ICE,
Dunestar, and W3NQN filters (the NQN filters are sold by Array
Solutions). All are designed for use between the transceiver and either
a power amp or matched antenna.

Last week, there was a thread on the NCCC reflector about bandpass
filters.There was general agreement that while ICE filters "work," they
are rather prone to fail at their rated 100W power levels, and everyone
who said they owned them reported failures. I've had two such failures
in the two years that I've owned two of them. Quality control is also
poor -- of four single-band filters and two 419's that I bought, all
arrived out of alignment. They were repaired at no cost, but I had to
pay shipping to Indianapolis, and was without them while they were being
repaired. My assessment is that they will fail if run at 100 watts, but
they are less likely to fail at the 30-50W levels required to drive a
power amp.

A west coast company, Dunestar, has been making bandpass filters for at
least a decade, and several NCCC members have owned and used them for a
while. All reports on Dunestar filters have been positive, and there
were no reports of failures.

Array Solutions sells bandpass filters designed by W3NQN, and described
in a QST article quite a few years ago. It isn't clear who builds them,
but I'd guess it's Array Solutions. They also sell switching systems for
these filters.

In terms of filtering performance, the W3NQN filters are quite superior,
followed by Dunestar and then ICE.

My two ICE 419s will be for sale as soon as I can replace them.
