I copy all CW in block capitals. I have always done that, and am used
to it, so that's what works for me. I can copy at almost any speed but
can't write much faster than about 35 or 40 wpm so I end up just taking
notes when in a QSO. 73 DE K6DDX

Subject: License from Panama?
To: info-hams@ucsd.edu
I am one of these hopeless creatures, who cannot raise the 40
marks per minute cw-cpy-speed to 60 which is the limit for the senior
class licens in our country. In the junior class we are allowed to phone
operations only on the 28 mHz band. As I am planning a longer yachting
voyage and I would like to be in contact with my fellow countrymen
through ham radio, it would be interesting to know if it is true that
you may buy for yourself a ham licens from Panama. How much would it
cost?

The Logikey keyer also is sold by the same company: Idiom Press. Last
I saw in an ad, the price for Logikey was $129 +s&H
BTW, Idiom Press is run by Bob Locher, W9KNI, top US operator in
the just released CW DXCC list. He is also the author of a book
on DXing and the author of the DXing chapter in ARRL Operating Guide.
He is an A1 operator.

I have had real good luck with a little 5 watt iron. All I do is let it
heat up for a while, then hold it on the pl-259 and the coax shielding on
the inside. If I wait like that for about a minute, and then melt the solder
on the tip and let it run into the hold and wait another min, I get a
real good connection.
See ya.

ARLD009 DX news
The items in this week's bulletin are courtesy of Steve, W9NUF; the
Northern Illinois DX Association; Ed, KB7E; and the Ohio/Penn and
Yankee Clipper Contest Club PacketCluster networks. Thanks.
PETER FIRST ISLAND. 3Y0PI has been very active and should remain so
until about February 19. DXers bemoaning the tough winter of 1994,
check this out. Last Saturday 3Y0PI had to QRT for 12 hours due to
a storm that battered the team with 80 MPH winds and dumped five
feet of snow on them. And this is during the Antarctic SUMMER/FALL.
Although some equipment was damaged, the team has made well over
20,000 Qs, more than 20 percent of their 100 Kilo-Q goal. Listen
for them on CW, SSB, AmTOR, PacTOR and satellite. EME operations
should commence soon. QSL CW via KA6V, SSB via AA6BB.
LACCADIVE ISLANDS. Geology students VU2STG and his newly licensed
XYL are on an exploration and study assignment. During free time
they operate VU7LI on SSB only. Please be patient as amateur radio
is not the primary purpose for their visits to the Laccadives and
equipment is minimal. QSL via VU2STG.
SOVEREIGN MILITARY ORDER OF MALTA. According to Luciano, I0JBL, the
1A0KM operation has been rescheduled for sometime in late February.
ANGOLA. D2EGH can be found on 14225 kHz at 2000z. QSL via CT1EGH.
Listen for D2/AA4HU on 14225 kHz at 1745 and 2000z.
BANGLADESH. S21AM has been worked on 14185 kHz SSB at 1200z. QSL
via Manju, PO Box 4000, Dhaka.
ETHIOPIA. ET3RA has been on 21250 kHz at 1600z. QSL via HB9CVB.
ET3YU works CW on 14035 kHz between 1600 and 1700z.
ISRAEL. For the past two nights, Chicago area hams have worked
4X4NJ on 1832 at 0420z.
MAURITIUS. Jacky, 3B8CF, is a relatively easy catch on both 80 and
40 meters. Try 3506 kHz at 0200z and 7007 kHz at 0420z.
QATAR. A71BH can be worked on 14215 kHz around 1300z. QSL via
OH6EEG.
FRENCH POLYNESIA. Walter, DJ0FX, is active as FO0PT from Moorea
Island of the Windward Group, IOTA OC-046. This one should be on
until February 19. Walter operates on all bands, mostly CW. Check
the low end of 40 meters between 0730 and 1000z. QSL via the DARC
Bureau.
SAN ANDREAS ISLAND. HK0/K1WGM has been worked on 160 meters around
1833 kHz at 0430z. Also check 80 meters on either 3505 or 3510 kHz
between 0400 and 0600z. QSL K1WGM.
CAMBODIA. An operation by Laszio, HA0HW, is slated to begin in
early April. The call signs XU9XA and XU0HW have been mentioned.
COSTA RICA. An operation is planned for February 17, 18 and 19 from
Guanacaste Island, a new IOTA island off the northwest coast. Call
signs will be K5MK/TI7 and TI2WLE/TI7. Try 14260 and 21260 kHz for
SSB, and 40 kHz up from the bottom edge for CW. QSL via K5MK.
THIS WEEKEND ON THE RADIO. Indoor sports this weekend include the
North American Sprint, Phone; the EA RTTY Contest; the New Hampshire
QSO Party; and the YL OM Contest. For more information on these
events, check pages 127 and 128 of January QST.

: Well lets look at some numbers and see. Lets assume

: That's obviously not good enough. 16 bits yields a SNR of
: 10*log(2^17)=51 db which is close enough for our purposes.
Use 20*log(x), since we're talking about a voltage ratio. An easy rule
of thumb is 6 dB of SNR per bit of quantization. It's actually a tad
better than that, since the quantization error is not constant;
sometimes the error is a small fraction of one LSB, sometimes it's up
to half an LSB. 8 bits will give you about 50 or so dB of SNR.
: Now the Nyquist limit says we have to sample at a minimum
: of twice the highest frequency in the audio. If we assume

Yes, you sample at that higher rate, but then you digitally filter with
a near-brick-wall filter and reduce the sample rate to very near the
Nyquist rate, via decimation. (Consider compact disks.) At the
receiving end you interpolate to raise the sample rate back to
something that can use reasonable reconstruction low-pass filters. So,
a more realistic analysis gives a transmitted 10 kHz sampling rate at 8
bits per sample, for 80 kbit/s.
: Codecs use various compression schemes to lower the effective
: bit rate. Delta modulation is one such trick, and LPC (linear
: predictive coding) is another. These are effective real time
: compression methods, but do suffer some artifacts. Or we can
: take a page from the newer high speed telephone modems and use
: LZW type on the fly lossless compression and complex modem
: encodings that use less than one baud per bit. Off the shelf
: modems can deliver up to 56 kb effective data throughput over
: voice grade channels wsing a base baud rate of 600 baud. That's
: not quite good enough though.
Even if you could make that degree of m-ary coding work on a radio
link, which I have my doubts about.
: Or we can abandon voice grade radios for the links and use purpose

: throughput for broadcast grade audio without dealing with the timing

: less than 70 kHz.
In my experience, LZW doesn't compress speech all that well. You'll be
lucky to get a 2:1 compression; you certainly won't get 4:1. Worse, you
won't get that compression consistently. Some parts of the transmission
will be compressed more than others, leading to timing/buffering
problems. You really want a compression scheme that is tailored to
speech.

8 bits is entirely adequate (see above). I'm not familiar with the
Motorola system, but I suggest that it is probably *not* using a
lossless compression scheme. That means that you'll experience some
additional noise/distortion, beyond quantization noise.

I've done some playing with MX-COM's CVSD codec. While I haven't
analyzed the SNR, "by ear" it produces reasonable reproduction at 32
kbit/s and audio I can stand to listen to (barely) at 16 kbit/s. At 64
kbit/s, its audio is entirely acceptable for amateur purposes. IMHO.

As I have stated before, and as even someone with a sixth-grade level of
literacy ought to be able to glean from the above exchange, it was
Mr. Hare who initially indicated that he was 'unsure' of his facts.
I responded that such a thing suprised me, having assumed that some
survey would have been made and its results disseminated to the staffers.
Since the issue in question was one of being in or out of touch with
the ham population at large, this was very pertinent.
He apparently mis-represented that; he indeed does believe that he has
facts at hand.

I guess I consider almost 20 years as an active ham a pretty good basis
for what my fellows do and don't do.
But let's look at these "facts" with a critical eye, shall we?
1. 35% is not exactly a clear majority, now is it?
2. The 42% includes 'or antennas.' Considering that
antennas are generally NOT plug-and-play items,
I'd expect MOST hams have to do it. Does this
mean the other 58% hate it?
3. The phrasing of the question begs for a higher
number. They 'enjoy' it. I 'enjoy' sunning on
the beach on a tropical isle. Doesn't mean I
do it, or get to do it, very often. But I would
submit that there are some vested interests in
asking the question that way. Such as the advertising
dollar. And such as justifying the existance of QEX.
4. The very existence of QEX can be taken to mean two
things; there is sufficient interest to support a
whole distinct publication; or there is insufficient
interest to put the material into the mainstream.
And that it really doesn't support conclusions any more than the average
Joe Ham's experience. Of course, Joe Ham spends his money based on his
experience, more than Mr. Bloom's data. And it is also that experience
which leads him to stay in the hobby rather than take up snowmobiling.

Yes, and that should have been your first hint that you were, well,

took the time to read and understand, you might gain insight
outside of the boundaries of greater Newington.

Aw c'mon. You mean to say you don't know bunches of hams with garages/

'a round tuit' along with some half-finished projects, and most of
the parts for this or that? Where have you been?

'Had experience' and where you work every day are two different things.
You get used to things. After five or more years, for example, it would
seem strange for me to work somewhere that had no internet access, even
though I know most people don't have it, and can remember what it was
like when it was a challenge to move data to a system four miles away.
That's normal. It really doesn't hurt anything, unless you *forget*
that you're in a different situation from most people, and fail to
accept that you have to do some different things to allow for it.

We must agree to disagree on this one. I, also, was opposed to no-code.
The difference between myself and the ARRL on this one is that I now
admit that I was being stupid, and club-ish, and elitist.

It was all over the older League publications.
Perhaps, if I have some time, I'll look up some citations.
Perhaps, Jon, you can fill us in on when the League and the editorial
staff thereof, conciously chose to change to a editorial policy where
home-brew was presented as an ancillary activity, rather than as an
ideal?

Gee, wouldn't it be useful if we had an ARRL staff which, instead of
attacking *MEMBERS* whose perceptions disturb them, claiming that
'all of your "assertions" are 180 degrees out' took the time to
figure out what's wrong? Why do some people look at the ARRL this
way? Why aren't a mojority of the hams members? Why do memberships
lapse?

I guess that means that the content is pretty well in tune with the
Directors' desires, then. Again, I base this on the facts that:
1. QST is an official journal
2. QST seems to be as good at covering opinions which
dissent from the League line as the National Review
is at covering liberal politics; conversely, the
League's positions are about as well covered in
QST as conservatives are in the National Review.
I rarely see something in QST which would help
a member make up his mind on an issue.
Perhaps it should be that way. I know I'd rather see it that way,
and see it honestly admitted, than see it denied.

The first thing that springs to mind was the review of the SWL receiver
which was in the PR section a couple months back. Did it really deserve
a full-blown review? It was a piece of equipment of only secondary (and
to give due credit, by the time the review was perused, I understood
it to be more like 'teriary') interest to hams. The question is, was
a full review necessary to establish that?

This is interesting information indeed! Certainly, there is some 'fault'
with Ramsey. It may even be that they knew what the likely results would
be. We'll never know.
However, the option to purchase existed all along. And, it seems to me,
that:
1. There was *some* responsibility to somehow inform the
readership of the problems seen with the first kit. After
all, these kits are probably one of the most appealing
items, especially to new hams, on the market today. QST
was very accomodating to Ramsey. Would that they would hve
been so to us! Again, this goes to an issue of being 'in
touch' with what hams need.
2. It is quite possible to 'tune' a kit. You can make sure that
all the components are within design tolerances, you can
take a very careful parts inventory, you can look at the
PC board with a very good magnifier, and you can generally
make sure that it's in the highest percentile of what you
turn out.
I wish, and I suspect some others do, that QST had pushed harder on this
one, and been more out front with those of us that pay the bills. Especially
when, as in this case, the initial work pointed to the possibility of a
serious problem.
It's a much higher calling to point out problems for the ham-consumer,
than it is to review the Conglomerate 1001D 8-band transceiver with
DSP; of course the 1001D is a more fun toy to play with, but 95%
of the time it works pretty much as advertised (across three color
pages of QST, I might point out).
What it comes down to is, you guys knew, or at least had an inkling,
that there might have been a problem. And you didn't tell us! I guess
I'd expect that either you'd find a way to tell us, or push to get
the Review done, to settle the matter.
And *THAT* is the kind of thing that I'm talking about when I claim
that there is a divergence between what the ham radio population needs
from the League's publications, and what they get.
I can think of no better example. And the 'facts' are Mr. Bloom's.
