this program covers 1.8-30mhz and deals with world-wide propagation predictions
specifically for contest type operations (i.e. not MUF predictions, but MOF and
LOF which are the max and min OBSERVABLE frequencies, not traffic handling
good copy frequency limits).

prediction software started out based on MINIMUF 3.5 and updates from NOSC.
it will provide predictions based on your lat/lon for the whole world in a
dos or windows graphical display. it doesn't know about dxcc, but it does
plot the whole world in rectangular, polar(north pole only), or polar
projection centered on your qth.

i will take them in trade to help improve predictions in future versions. but

P.S. Please do construe this as adversiting for MOF software which can't be
found in any issue of QST or NCJ... Only here on the web!

Subject: Station Building
Message-ID: <199606080152.VAA25410@vixa.voyager.net>
I seek the wisdom of the multitude.
I have been building an inverted-L antenna. It has an 80M CW trap and is
resonant on 1825 and 3575 approx. Seems to work fine. The vertical section
is 58' as that is what my trees will allow. The 80m trap ends up being about
six feet from the top end of the vertical section. The horizontal section
tips up a bit. I have the feed point mounted at the top of a ground rod, not
deep, and it sticks above the ground about 1.5'. There are six 133' radials
and about eight 68' radials, all insulated #16 copper, laying on the ground.
My question is, given the height limitation, would it be a better antenna
with the feed point raised to about 10' with the radials elevated, loosing
an additional ten feet of radiator in the process? Or would it be better to
leave it ground mounted and elevate the radials. Maybe just elevate the long
radials.
I haven't modeled this one because I don't know how to model the Undilla
KW-80CW trap with AO 6.5 Maybe some of you have already done it.
This inverted L will be the 80/160 tx antenna for our ZK DXpedition on
Rarotonga in July. It may have to be ground mounted, radials included. If we
can get it elevated the ground losses might be less.
The feed point, when operated on 160M, is fed via a 28:50 un-un. I take this
out when on 80M. Bandwidth is a bit on the narrow side, but I take that to
indicate the ground losses aren't prohibitive. The MFJ says the feed point
is about 30-35 ohms without the un-un on 160M.
I intend to make up a bunch more shorter radials, about 16-20', just in case
it has to be ground mounted.
Anyone care to pass along your thoughts?
Since this is directly related to contesting, station building,
DXpeditioning, antenna technical, etc. I am not shy about posting this one. :')
Please respond to aa8u@voyager.net, tnx in advance.

Subject: Vanity Calls
Message-ID: <01BB54BC.53848840@grail901.nando.net>
As I promised, I've written a program to extract the vanity calls issued from
the FCC's daily database updates on their ftp server. Here is the output from
the program from the first 3 days of vanity calls: 6/4 - 6/6. It appears that
the first vanity calls were not issued until Tuesday 6/4. I'm putting the
info here initially for comment. Please comment on the content and format and
let me know what other info you would like to see extracted for each entry.
I don't intent to continue putting the data here because it is of limited
interest to non-US subscribers to CQ-CONTEST. I'll probably put subsequent
data on my personal web page (which is still under construction).
Here are the current caveats/info regarding the data:
- The data comes from the FCC's ftp server. Point your web brower at:
ftp://ftp.fcc.gov/pub/XFS_AlphaTest/amateur
- If you're familiar with the databases there, I'm assuming that vanity
calls are indicated by a 'S' in the type_purpose field of the appl
database. According to the readme file, 'S' indicates a Special Callsign
Change. So far, the published list of issued vanity calls matches this
character in the database.
- The data is sorted by callsign. If you'd like to see it sorted
otherwise let me know.
- A 'C' in the class category indicates a Club call. A 'P' in the class
category indicates Technician Plus. I think the rest of the class values
are self-evident.
- If the vanity call is for a Club call, the OLD CALL is actually the call of
the trustee.
- No, the program is not available. I will support it, but I hacked it
together in about 3 hours and it has only been tested with limited data
and it has my assumptions about the FCC's databases (which are known to
have problems). For the curious, it is 2 pages of C code.
