According to "New Products" in the May issue of QST (p.73), Rockwell Collins
has an upgraded piece of software called PropMan 2000 which uses current data
from the Internet, as well as time-of-year, ionospheric and solar info, as well as
equipment parameters to factor a propagation forecast. Unfortunately, the URL in
QST doesn't lead you to the product, or Rockwell Collins, for that
matter! Follow QSTs link PropMan,
and you'll find yourself in sunny Florida, looking at property!!
Well, sorry 'bout that, as they say, HI! However, if you go to
PropMan-2000
Propagation Resource Manager, you will be able to review the features and benefits
of this program. Ah, well....good ol' The Ham Weblog to the rescue!! HI!
PROPmAN-2000 is designed for Windows 95/98.
In Rockwell Collins' words:
|
|
Originally developed for military and government use, PropMan has been modified to be
more user-friendly and is now available to professional and amateur HF operators of
all kinds. A newly developed Windows 95/98® /Windows NT® interface, online help, and
the implementation of VOACAP are just a few of the improvements.
|
|
A-HA!!
Ok, now the problem's out! Somebody in production at Newington missed a 'lil
tidbit [the 2000.com portion of the URL]. Here's the info straight from
Rockwell Collins:
Demo Available on the World-wide Web
|
|
A demo version of PropMan is available at http://www.propman2000.com/. The interested user
can experiment with PropMan capabilities by downloading the demo version and following
setup procedures. A fully functioning version will be provided upon purchase of PropMan
2000TM Version 1.0.

QSTs It Seems to Us
Here's another interesting item from May QST. This time, its Dave Sumner's
editorial. Dave puts digital modes, like PSK 31, in perspective this month. In fact, it
sounds like we're flocking to digital in unprecedented droves! May well be; in any case,
the handwriting seems to be on the wall...Only problem is--is it in 1010101010's,
dididahdahdidi, or that warbling tone of PSK31? Anyway, Dave brings to light yet another
development likely to overtake all of in the not-too-distant future: Digital Voice.
And, he includes a link at ARRL for more reading:
Technology Task Force.
The Technology Task Force report's most interesting and compelling information is presented
in Attachments A and B:
|
|
Attachment A: [Technology Working Group Report] cites "higher digital speeds and
digital voice" as two thrusts amateurs feel they need to make an impact. FCC's Hatfield's
June 2000 speech is noted: Hatfield focused on "software-defined radios (SDRs)" as
an area in which amateur radio design should move.
|
|
|
|
Attachment B: [Digital Voice Working Group Report] describes the League's Digital
Voice Committee's inital report -- generally a summary of status quo and where to go from
here.
|
|
Although Technology Working Group Report gets a bit wrapped up in League procedure-ese,
several conclusions are worthy of note:
- "...384 kbit/s is (needed for) full-frame/-motion, digitally-compressed video
|
|
- "...of three digital voice technologies (LPC-10, MELP and AMBE), APCO Project 25
and other systems have selected Digital Voice Systems, Inc. AMBE...."
|
- ARRL to encourage a supply of reasonably-priced digital-voice chips
for amateur use
|
|
- ARRL to work with US amateur manufacturers and Japanese industrial and
amateur associations to encourage interest in digital voice
|
- ARRL to Promote digital-voice awareness through QST articles
|
|
- ARRL to develop and test scalable protocol for 2.4 kbit/s at HF; and 4 - 9.6 kbit/s
at VHF/UHF
|
Quite frankly, the Digital Voice Working Group Report loses me quite quickly! Now, that may
well be time-of-night, or just simply (and more likely) over-my-head syndrome, but...
hey! Go read the reports. At least know what's going on, HI! In any event, sure seems like
there's lots afoot for the future of advanced amateur technologies to master. Now, lessee...
Ie=Kear, right? Well, that's what my ole buddy LeRoy told me,
anyways, HI!

Is your clock right? What about your watch?
Check at Atomic Time!
|
WOW!!! There's sure something here for just about
everyone, HI! If you can't find a clock or watch to your liking here, maybe
you should go back to the Sundial.
Gee, did you know that each second can be calculated by counting "9,192,631,770
vibrations of a cesium-133 atom in a vacuum"? Yep, they say so! And, they
have more than 200 timepiece models from which to choose. Have one in your price
range? Probably, since their range is $19 to over $2000. Hey...I don't think you
can get one from that other company [the one "takes a licking and keeps
on ticking"] for $20!
But we're not in the advertising business, so enough of that! The site is well-designed,
but I was distracted by the flashing animation at the top. I expected to be
whisked away to exotic timepieces when I moved my mouse over the image, but was disappointed,
although the animation does continue on to display a v e r y rapid sequence of
clocks and watches. I'm not sure this feature is all that useful.
Atomic Time does feature one clock which they label as specifically marketed to amateur radio
Atomic Clock
Amateur Radio with Alarm & Temperature. However, I don't see any reference on the linked
page to amateur radio! Am I missing something?
Now, here's a neat clock:
Atomic ZEIT Modern with Temp. and Hygrometer. Caution, though...Be sure to click on
the link below the image. Clicking on the image takes you to an intermediate page and
you have to search on the page to find the same image. Having temperature and barometric pressure
displays is a nice touch. Wonder if you can mount external sensors to get condx outside?
One last comment: The site also supports online ordering, so you can buy right now!

Restrictive Covenants got you down? Call
International Antenna Corporation.
With all the talk lately in QST and other ham pubs, it sure seems
that CC&Rs (aka Restrictive Covenants or deed restrictions) are the bane of amateur
radio....at least here in the US. Well, then just go out and get yourself a bazooka!
No, not the military kind...the antenna kind! Well, obviously, some
stealth is in order, so let's look at International Antenna's
Stealth Bazooka.
The claims are impressive:
- Covers 20, 17, and 10 meters w/o traps, coils, or tuner
|
- rated at 1.5 KW PEP?
|
- Extensible range to 15, 12, and 6 meters with use of tuner
|
My ?: Does the power rating apply
only on 20, 17, and 10? Look closely at the way the specs are presented.
Power is mentioned immediately after these bands, but not mentioned at
all on the Specifications page. May not be a problem, but if you consider
this antenna, I'd sure ask, HI!
Also, be sure to check the wind rating for the "flag pole" with flag flying. Considerably
less than w/o. Again, reasonable; but, better to know ahead of time. Of course, you really
shouldn't fly Old Glory in inclement WX anyway!
Be sure to check both the Specifications
and the SWR pages, too. SWR looks to
be impressive, but then the Bazooka is known for being broadband, so that's good.
And, Int'l Antennas includes the Installation Instructions right on the website. Now try and
misplace those instructions!! Darn good idea!

The ARRL Letter [Vol. 20, No. 19, May 11, 2001]: Alinco Shifts North American Distribution
|
Amateur Radio manufacturer Alinco has closed its US branch in Torrance,
California, and shifted its North American distribution to an Ohio firm.
Alinco product distribution and customer service now are being handled by
Atoc Amateur Distributing LLC in Covington, Ohio. The change was effective
May 1.
A news release posted on the Alinco Web site says that Alinco will continue
to be "a very committed, viable player in the Amateur Radio marketplace" and
that all Alinco warranties "will remain in force and continue to be honored
through their term." Alinco will exhibit at Dayton Hamvention next week and
will sponsor the W8BI special event station in the outdoor exhibits area as
it has in past years.
In addition to dealer distribution, the Atoc facility in Ohio is taking over
customer support and out-of-warranty service of Alinco products and sales of
Alinco parts. Parts sales have been temporarily suspended during the
changeover, and service could be disrupted for a time as well.
The announcement said Alinco will concentrate on designing and manufacturing
products from its Japan headquarters in Osaka and factory in Toyama.
For more information, visit the Alinco Web site, http://www.alinco.com , or
contact Atoc Distributing LLC, 23 S High St, Covington, OH 45318;
937-473-2840.
