I need English documentation for the program TFPCX.

This is a piece of software that lets one use GraphPac
with a tnc in kiss mode or with a Baycom module.

Any help appreciated.

SYNOPSIS OF ACT
--------------------

             Solar activity was low. Region 7671 (N10E52) produced a
       C1/SF at 15/0757Z.

            Solar activity forecast:  solar activity is expected to be
       low. Region 7670 (N11E38) and Region 7671 have slight M-class
       flare potential.

            The geomagnetic field has been at unsettled to active
       levels at mid-latitudes for the past 24 hours. Some high
       latitude stations reported severe storm conditions for the
       period 15/1200-1500Z. Energetic electron fluxes have been at
       elevated levels since 07 Feb. One historic note regarding the
       past ten days. A-Fredericksburg values have exceeded 20 since
       05 Feb 94. This has only occurred two other times since 1957
       (beginning 27 Mar 1984 and 04 Jun 91).

            Geophysical activity forecast:  the geomagnetic field is
       expected to be unsettled. A coronal hole may bring a return
       to storm conditions on day three.

                        Major-Severe Storm    05/01/01

                        B.  High Latitudes
                        Active                25/30/30
                        Minor Storm           15/25/25
                        Major-Severe Storm    05/05/05

            HF propagation conditions continue to show signs of
       improvements, particularly over the low and middle latitude
       regions.  However, high and polar latitudes are still
       experiencing poor to occasionally very poor propagation.
       Improvements should continue until about 17 February when
       effects from the second coronal hole noted above should herald
       a return to slightly more disturbed conditions.

NOTES:
     All times are in Universal Time (UT).  Characters preceding begin, max,
     and end times are defined as:  B = Before,  U = Uncertain,  A = After.
     All times associated with x-ray flares (ex. flares which produce
     associated x-ray bursts) refer to the begin, max, and end times of the
     x-rays.  Flares which are not associated with x-ray signatures use the
     optical observations to determine the begin, max, and end times.

     Acronyms used to identify sweeps and optical phenomena include:

          II        = Type II Sweep Frequency Event
          III       = Type III Sweep
          IV        = Type IV Sweep
          V         = Type V Sweep
          Continuum = Continuum Radio Event
          Loop      = Loop Prominence System,
          Spray     = Limb Spray,
          Surge     = Bright Limb Surge,
          EPL       = Eruptive Prominence on the Limb.

Subject: Facility assessment forms for ham radio operations
To: [e-mail]

   I'm part of a newly formed ham/amateur radio emergency communications
   response group. One of the first things we've decided that we
   need/want to do is an assessment of our primary and secondary
   communication response points (and then work out from there).

   Towards that goal we're trying to develop a form that will document
   the salient issues for us. For example:
   . directions to the site
   . possible problems: bridges/overpasses, flood plain
   . resources available: power, antennas,  radios...
   . issues of concern: where and how to run cables, RF interference...

   We have a pretty good start at what we think should be on the form, but
   we're wondering if anyone else has already done a similar type form and
   if they'd be open to sharing it with us?

Thanks much.

Subject: Ham Radio FTP area on World
To: [e-mail]

This is a periodic reminder that the Boston Amateur Radio Club maintains an
FTP area on world.std.com (192.74.137.5) in pub/hamradio.

This area is accessible via: anonymous ftp, gopher, and World Wide Web
(and possibly other methods I'm not yet aware of).  World is not
*fsp*-able yet (I asked them).

Via Gopher, the easiest path to the area is by selecting the following
from World's main menu:

18. Membership and Professional Associations

 3. Boston Amateur Radio Club

  And go from there...

Please feel free to browse through the area.

If anyone has any questions about it, please do not hesitate to e-mail me.

Also, up-to-date copies of the files on the ARRL's information server
([e-mail]) are available in the directory pub/hamradio/ARRL/Server-files.

All text files are uncompressed, so they are both retrievable and
viewable via Gopher and World Wide Web.  (If you have any troubles with
any text file, please e-mail me).

Source code for programs is always welcome.  It can permit people to use
those programs on other computers with other operating systems.

The implication is that Jeff's approach was this.  Do you knoe something we

Excuse me?  In the 20 or so years I've been building kits, especially Heathkits,
I've had at least 90% of them work from the moment the power was turned on.
This includes the Heathkit dot matrix printer I built with both electronic
and mechanical assembly.

Err... settle down Cecil; I think Jeff is mentioning that the assembly
manual didn't say you needed to stretch the coil.

Settle down, Cecil.  Jeff had a certain experience that differed from yours.
I will say, flat out, that John Ramsey indeed bad-mouthed Jeff Gold by
name during a phone call with me  despite the fact I asked him not to do so.
This is *not* good business, no matter how much of a fan you are.  This appears
to be why Jeff felt compelled to make his post.

Subject: kits
To: [e-mail]

   Something that has not been clear to me from the start of this thread
   is why the people who are smart enough to de-bug assembled kits that are
   obviously in dire need of it are not smart enough to assemble the things
   from their own components in the first place.   Is it cheaper buying one
   of these kits than it is buying the individual components?

Scrounging around for all the parts you need to build a project is not
all that easy.  I know.  I am building the swr/power meter present in
the ARRL handbook and am having a beast of a time finding the proper
ferrite beads.  The local vendor does not carry Amidon beads and I
can't find out the appropriate values for the Amidon part so I can buy
the equivalent.  The chips needed required shopping with several
vendors before I got everything I needed.

Get a medium wave receiver, tune it to a clear channel and go about looking for the
source of the noise. It may be a bad joint in a power line, it could be a faulty
appliance but it is most likely to be a computer.

Check out for sentral heeting controllers, theft alarms etc. If you get really
frustrated, try turning off all the ac power and running the rig off a car battery.

If you can isolate your own house, prey for a power cut.

I assume you don't live near a welding shop.

    Here in Britain, there are no required specs for spurious outputs,
we're held responsible for any problems due to any at any level. I know
that the US FCC has put actual numbers on required performance (sounds
like an improvement on our requirements, to me). So, just from personal
curiosity, what are the consequences to an amateur who puts a radio on
the air that does not meet the FCC specs ?

CQ netters,

Does anyone out there have a program that makes use of the Sound Blaster
ASP card for morse coding/decoding ??

The Hamblaster has a 14 bit A/D.   The add-on (I don't have the details
about this) may use a sigma-delta A/D.  There may even be a super fast
sampler to do I.F. processing in the works.

  Why do they call them concetration camps?
  When people go there, do they really concentrate?
