Subject: 2K Filter FT990
To: [e-mail]

About a year ago I installed a 2K SSB filter in my Yaesu FT990.
I've found that the 2K filter is a shade better than the 2.4K SSB
filter that comes with the unit.

A year ago I sent the 2K filter back to Yaesu and they replaced
the crystal but I found no improvement.

A friend of mine also has a 2K filter in his 990 and he also
finds it practically useless and also views the 2K filter as
a waste of money..

I thought I'd share my experience with the 2K filter in case any
one on the net was thinking of purchasing one.

Are there any 990 owners out there who are happy with the 2K filter ?

A side note, the 2K filter in the FT1000 works great. Yaesu said
the 2K filter works like a 1.8K filter because it is cascaded.

Subject: Anyone here familiar with extended-play recorders?
To: [e-mail]

 After trying to record the audio from the last few broadcasts of
shuttle-ground communications by WA3NAN, having a recorder capable of recording
at a much (4 times or greater) slower speed than the usual mini-cassete
 standard speeds is looking
like a decent option.  Does anyone in the group have experiece with
such recorders?  Any firms dealing with such recorders?

My preference is to a recorder of a walkman-type design, recording at a speed
of 5 times or slower than normal (10 hours on a 120 minute tape).  I have
seen one similar design, but it recorded at 4X slower than normal.

News on any other designs (there seems to be VERY few of them available) would
be appreciated.

Thanx,
R. Camama

JVFAX with the op-amp interface is cheap shareware and works well.
SSC HF-FAX is a very polished performer.
They both work well but I found the the SSC offering was more convenient. The
JVFAX interface works with the SSC, but not the other way round. It also
works with Hamcomm (RTTY), which may be a consideration. Hamcomm is just so
damned pretty !

To: [e-mail]

To the author of FFT or to anyone who can reach this person:

I have made a major improvement in fftmorse which uses a radix
4 FFT, thus has MANY fewer multiplies and does a 64 pt FFT in
less time than your 32 pt and I could do a 128 real FFT in almost
the same time as the 64 pt using a trick.  I would like to send
you the code for your perusal but your mail address in canada
rejects you as an unknown user even though I can get directly
to the site.

Sorry for imposing this on everyone else.

Now, to do the same thing for sstv, fax, etc. ;-).  These sound
blasters are going to BURY all the DSP boxes.

The only thing that is certain is the number.  It represents the
area where the amateur was residing when they received their
call.  In the 1970's, the FCC (our regulatory agency) began to
allow amateurs to keep their call when they change residence into a
different area.  This is why, for instance, my call is WB0FEW but
I now live in the 5 call area.  I originally received my call when
I was residing in the 0 call area.  Maps showing the areas can be
found in the callbook, gotten from the ARRL, and many other
amateur radio suppliers.

We also have a new higherarchy in call signs.  The American amateur
service has different levels of licensing.  Amateurs may choose to
receive a new call sign representative of the license class when
upgrading or renewing their license.  Amateurs that have been
around since before the 1980 will have a W, WA, WB, or K call
(unless they have chosen to receive a new call).  The W call could
have 2 or 3 letters after the number, the reset would have three
letters after the number.  A WA or WB call usually indicated that
station was a Novice class station first.

Today, our call signs are still issued by area.  The following
shows how the new call signs are issued based on license class:

Novice/Technician: KX9XXX
Technician Plus/General: N9XXX
Advanced: W9XXX, KX9XX
Extra: W9XX, K9XX, N9XX, AX9X, KX9X, NX9X, WX9X, AX9XX

(X=any character, 9=call area)

There are still special prefixes for non-continental US areas such as
Hawaii, Alaska, and other territories.  Currently, the last call sign
listed for each class above is what is being issued. The others have
been used up.  Also, I may have left out some.

Now if this doesn't confuse you, I don't know what will! :)

Hope this helps.

73,
Pete, WB0FEW, Rowlett, TX, USA

I don't know what kind of equipment or power you are running
through your antenna, but I'd guess a substantial corona discharge
around the antenna would discourage the birds from using it as a roost.

The "audio annoyer" I've got in the barn works well.  Maybe a little
too well as I also find it very annoying.  I had bought others previously
that I couldn't hear, but they did nothing to get rid of the rats and
birds.  Maybe the emperor had no clothes?

Subject: Soundblaster vs Hamblaster
To: [e-mail]


Over the past few weeks I received several e-mailings from
persons inquiring about the differances between the Soundblaster
and the Hamblaster.

The Soundblaster is a soundboard with circuitry that
performs A/D and D/A functions.  It also has one or two
(depending on the model) FM audio synthesizer chips can
be used for speech synthesis.  It even has a DSP chip that's
used for processing data for the MIDI and CD interface and
speech recognition (the 16 ASP only). The Soundblaster uses
a DMA (direct memory access) controller IC to access the PC's
RAM.  A DMA channel provides high speed data aquisition for
sound sampling and display.

One drwaback is that the DSP is not really a signal processor.
It only processes the digital data from the MIDI and CD interface.
To conserve disk space the Soundblaster 16 and 16 ASP has an
advanced processor that performs sound compression but it can't
run complex filters or perform adaptive filtering.

The Soundblaster is great if your a musician or if you want to
play a CD through your PC.  It's not very good in Ham Radio
applications where your trying to filter signals that are in
the noise or decode FSK.


The Hamblaster, on the other hand, uses a Texas Instruments
TMS320C25 digital signal processor.  I has it's own program
memory  that stores filter or modem programs.  It runs the
programs in real time and is independant of the PC of the
PC memory.

Data can be transfered from the DSP to the PC via the I/O
port but only faster machines (like a 386-33 or 486-33) can
record sound.  The I/O port is also used to load filter
or modem programs from a binary disk file to the DSP,s RAM.
The DSP can then run the program in it's own high speed memory.
The Hamblaster uses 35 ns RAM chips where a 486-33 normally
uses 80 ns rams.

The Hamblaster only samples 15 kHz.  This may sound slow compared
to the Soundblasters 22 kHz rate but radio communications only
goes from 300 to 3kHz.    You only need to sample twice the
maximum frequency.   A slower sample rate gives you more processing
time.

This is certainly true of the San Francisco Amateur Radio Club.  But
on the airways around here (especially on the "going to work" and
"going home" commuter nets) I hear my peers (30 years old).  How to
