Subject: A new DSP for Ham Radio
To: [e-mail]

 The Hamblaster Update

Over the past several months I posted updates about a
DSP "The Hamblaster" that Will Torgrim (N9PEA) and myself
are developing.

We are focusing our efforts on a packet modem that allows
the user to improve H.F. reception by interfacing the Ham-
blaster (it mounts inside a PC) to a transceiver and a
packet or all mode TNC.  Modems/filters for RTTY, Packtor,
Amtor are also under developement and are compatable with
the same software.

I am happy to report several new innovations.

1) The packet modem is loaded from a disk file and allows the
   user to interface to his radio using an A to A (analog to
   analog) connection.  The DSP outputs a regenerated FSK
   signal that can be tuned to match the TNC or RTTY modem.
   The DSP also has a digital connection (A to D) for inter
   facing directly to the TNC's digital logic.  I use a cable
   that connects a PK232 via the external modem port.

2) Using MS DOS Windowing Software an on screen control panel
   with pushbuttons and slidebars allows the user to control
   the DSP modem. The user, for example, can control the
   filter frequency, carrier detect and AGC, to name a few.
   If an external amplifier/speaker is connected to the DSP's
   output, you can monitor and hear the signal at the filters.
   Using an oscilloscope (connected to the DSP output) you can
   also analyze the carrier detect, AGC and data.  The test
   points are displayed (on the PC) as a block diagram.  You
   select a test point by moving the mouse cursor to it and
   by pressing the left mouse button.

3  There are two slide bars that control the filters center
   frequency and provides a tuning aid.  Both slide bars have
   digital readouts that indicate the frequency in Hz.  You
   tune the filter by moving the mouse cursor over the filter
   tune slide bar button and when you press the left mouse
   button the slide bar button moves.  There's also a push-
   button that activates an auto tune feature.  When it's
   enabled, the filter tune slide bar tracks the frequency
   counter slidebar.  The auto tune feature works so well,
   it can even lock to a packet signal.   It's also great
   for tuning RTTY, Amtor and Packtor.  Even if your tuned
   off frequency (let's say a center frequency of 1200 Hz)
   the DSP locks onto the received signal and feeds the TNC
   with a regenerated 2125/2295 Hz tone.

4  Using the oscope control panel, there's an on screen digital
   storage oscilloscope that allows you to capture 4 signals.
   You can select 4 out of 8 test points by cliking on the modem
   block diagram.  When you click on the "SNAP" button a green
   window shows all 4 signals and the RMS value.  You can even
   resize the display's amplitude and time base.  The snap shot
   is done without interrupting the received signal.

5  I am working on software for Windows that will impliment
   all of the features the DOS version provides.  The Windows
   version will have better graphics with animated buttons.

6  The best feature is, when you have the modem setup correctly
   you can leave the software, run some other application like
   your TNC software and the DSP keeps on going and going and going!

Ongoing developments;

1  Post detection carrier detect.
2  HDL protocol decoding
3  Morse code detection/regeneration
4  Adaptive voice filter.
5  FFT analysis.
6  Sound recording.
7  DTMF & PL tone detection.

Well speaking of first contacts...the following was attached to the door
 here tonight along with some pizza junk ads and other fluff from the
 building management....

The First Christmas Radio Broadcast

        Christmas Eve in 1906, sitting at his radio in the mid-Atlantic, the
 ship's wireless operator could hardly believe his ears.  Instead of Morse
 Code, he heard the strains of a violin, followed by a crackly voice that
 seemed to come from nowhere: "If anybody hears me, please write to Mr.
 Fessenden at Brant Rock, Mass."
        The wireless operator had tuned into the world's first broadcast of
 a program of words and music.  Thus was the beginning of radio telephony
 which could broadcast words and music by using continuous waves of sound.
        His radio audience consisted of professional radio operators on
 board ships or a shore stations monitoring navigation or military
 intelligence.
        Fessenden's Christmas Eve concert was broadcast from a 420 ft. mast
 at Brant Rock, Mass. and has a range of 200 miles.  In it he played the
 famous Largo from Handel's opera Serse on a phonograph, making him radio's
 first disk jockey, and a woman sang some festive carols.

Subject: Modem Software to Alert Many Pagers?
To: [e-mail]

There is a program called Snap Page that is distributed by Metromedia
Paging here in the New England area. It has a way to group various
pagers together under a single group. You could send a message to the
whole group... can be anything you want.

We use Snap Page extensively here for our notification process for our
nuclear power station's plan. Many of our users are hams... but most
are Emergency Management Agency personnel.

So... I guess I would ask your paging company about the software!

BTW... Snap Page is a application based on the 80x86 processors. I have
not found any "acceptable" software for my Mac at this time... but I
recently saw an ad somewhere for a version with a retail of about $150!
Seemed pretty steep to me!

Subject: Repeater calling procedure (Was: Elm
To: [e-mail]

My $.02 worth:
I've often heard people getting ribbed for calling CQ on a
repeater. It is, after all, a (shutter) imported from hf'ism
and (like QTH for "where are you now") _can_ rub people the
wrong way. Like Jay said, in Texas we always just assumed
that a "monitoring" meant the caller was open for conversation.
Around the Atlanta area I haven't heard CQ yet, but then again
I haven't had much luck scareing up a contact when I "monitor".

But still, "monitoring" pretty simply says "Hi, I'm
currently listening on this freq and would be willing to talk
to some other amateur if they'd like to discuss pretty much any
subject." Whew! Now THAT would be silly!

MY biggest gripe is the guy yelling "testing. TESTING." and then
does not responding when I offer to help with a signal report.
Maybe their speakers are busted but their mic's are good?

My TH78A draws only 0.25mA from its battery with the power off. If you
are using an external 12 volt supply there will be a 2mA drain due to the
battery charging circuitry with the battery pack removed.

Derek.

Once again you attempt to utilize fundamental physical principles to
advance your treachery.

We who enjoy reading frivolity between the covers of QST simply KNOW our
linear amplifiers boost the kinetic energy of the radio waves we emit.  Our
roof-mounted antenna recoil with such force the emission of a single dit
cracks the joists in the ceiling.

We're talking raw power.  Manly power.

Keep Max Planck and his quantum-bleeding-mechanics in the classroom where
they belong.  Real men run three-phase 440 into their shack.  Real men have
blisters on their balding scalps from high-power RF proximity effects.
Don't tell US our photons aren't stronger than those whining 3KW QRPers.
We have the radiation burns to prove it.

You're being too sensitive.

Its Fred Maia's publication. He can put whatever he likes in it.
If you don't like his blatherings, don't subscribe to his newsletter.
Its that simple.

I got sick and tired of Wayne Green's garbage, and voted with my

Subject: Yaesu FT-11/R mini-HT: a first look
To: [e-mail]

I just got one of the first FT-11/R mini-HTs from Yaesu, and
I thought folks might be interested in some first impressions:
Wonderful! Terriffic! Fantastic! Hock your banjo and buy one!
The FT-11 is tiny, about 4x2x1 inch. It's much less of a handfull
than the Icom 2sat, and slips nicely into your shirt pocket.
Features galore, including alpha-numeric readout for named
memories, DTMF code squelch, paging, digital message paging (!)
plus tons of other stuff. The standard battery pack fits
entirely within the radio, and provides 1.5 watts on high
power. Other packs (larger) get you up to 5 watts if you want.
The keyboard is plenty big enough even for us fat-fingered
hams, and the keys seem very sturdy, with a nice positive
click. The display and keypad light up on demand. All in all
a wonderful little package; so far, I haven't found anything
I don't like. The only funny thing I've noticed is that the
touch tones seem to be delayed by about a quarter of a second
from when you hit the key. Don't know if this is a fault, a
feature, or just something I'm doing wrong. As you can tell,
I like it a lot. I've always been a sucker for little radios,
and this one really hit me where I live. The nice thing about
it is that I don't have to sacrifice much in the way of performance
or features to get the small size. I've compared it side by
side to the new Kenwood, and it's no contest. The Yaesu wins
hands down in size (quite a bit smaller than the K'wood),
features, and overall "niceness". Check it out; you won't
be disappointed. My local ham store is selling them over the
counter for $313; you can probably get them for under $300
from the mailorder guys.

Standard disclaimer: no connection with Yaesu, just a
satisfied user.


P.S.:
I hope to able to address the RF performance in a future
post, based on some bench testing I'm trying to arrange. My
impression based on use in our much-loved "intermod alley"
here in Tysons Corner, VA, is that it's better than average.
