Wes- I?m inclined to agree with Jeff because I did that modification.
The easiest way to lower the ground plane is to remove the bolt that holds
the radial plate to the antenna base and insert a piece of threaded rod of
the correct length. I just threaded a piece of solid aluminum rod on the
ends and it worked well. I can send you a pic if you want to see it.
Because I had 2 used EB432 I was able to do a head to head comparison and
there is a noticeable improvement. But it is not as good as a small CP
beam. If you have to run omnis I think the mod is worth it.
Good luck.

Hello,Just purchased a Kenwood TS2000.Can anyone tell me if the built TNC
can handle digital modes like Amtor and FT-8?I read in the Manuel that it is
limited on packet operation.This what the Manuel says:
This transceiver has a built-in TNC which allows you to use basic (not full)
packet applications.It also says this:Since the built-in TNC has been
designed to work with the Packet Cluster Tune {page 53} and Sky Commander
II+ {page 83} functions, some of the enhanced TNC commands may not be
available.?Anyway I have a Rigblaster so not s problem but if the built in
TNC can handle it,would make it easier.I use FT-8,RTTY and Echolink and will
use SATPC32Thanks in advance.

An International Space Station school contact has been planned with
participants at Istituto San Paolo delle Suore Angeliche, Milano, Italy and
Istituto Comprensivo Di Merone - Mons. A. Pirovano, Merone, Italy on 21 Nov.
The event is scheduled to begin at approximately 09:12 UTC. It is
recommended that you start listening approximately 10 minutes before this
time. The duration of the contact is approximately 9 minutes and 30 seconds.
The contact will be a telebridge between NA1SS and W6SRJ. The contact should
be audible over the west coast of the U.S. and adjacent areas. Interested
parties are invited to listen in on the 145.80 MHz downlink. The contact is
expected to be conducted in Italian.Watch for live streaming at:
Istituto San Paolo delle Suore Angeliche Milano:

Istituto San Paolo delle Suore Angeliche
Private school in Milano city, our students are children from 1 to 13 years
(nursery, kinder garden, primary, secondary 1st level).
Istituto Comprensivo Di Merone - Mons. A. Pirovano
The School is an Istituto Comprensivo, it means that includes 3 school
levels: primary, elementary and junior school (Scuole Medie). It is located
between three municipalities: Merone, Lambrugo and Monguzzo, but the
logistic offices are in Merone. Merone is a small town between Como and
Lecco, north of Italy.
The junior school is composed by different kind of school hours from 30
hours, base level, to 38 hours, that are managed with some laboratories, in
particular three scientific ones.
Participants will ask as many of the following questions as time allows:
1. Come interagisci con CIMON? Capisce se sei triste o felice e ti
parla?
2. Quali sono gli strumenti che utilizzi di pi? nel tuo lavoro?
3. Cosa fate voi astronauti durante le manovre di reboost?
4. Chi o che cosa pu? trarre vantaggi dalle missioni dell'uomo nello
spazio?

nello spazio?
13. Nello spazio si ha una percezione diversa del tempo?
14. Paradosso di Enrico Fermi o equazione di FranK Drake: cosa ne
pensa?
15. La ISS inquina nello spazio?
16. Tra poco dovremo fare l'importante scelta della scuola superiore.
Come hai fatto tu a scegliere?
17. In base alla tua esperienza, ? pi? difficile adattarsi alla
microgravit? oppure riabituarsi alla gravit? terrestre al rientro?
18. Se potessi tornare indietro nel tempo, rifaresti tutto ci? che hai
fatto finora?
19. Nei momenti liberi vi divertite con la microgravit??
20. Che sensazione prova a "vivere in due mondi", uno con la gravit? e
uno senza?
21. Per quanto riguarda le sensazioni, il sonno nello spazio ? diverso?
22. Cosa ne pensi della possibilit? di costruire una base operativa
sulla Luna?
23. Se fossimo pronti ad inviare un equipaggio su Marte, tu vorresti
farne parte?

13. Does space have a different perception of time?
14. Enrico Fermi's paradox or Frank Drake's equation: what do you
think?
15. Is the ISS polluting outer space?
16. We will soon have to make the important choice of high school. How
did you choose yours?
17. Based on your experience, is it more difficult to adapt to
microgravity or get used to terrestrial gravity on re-entry?

About ARISS
Amateur Radio on the International Space Station (ARISS) is a cooperative
venture of international amateur radio societies and the space agencies that
support the International Space Station (ISS). In the United States,
sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American
Radio Relay League (ARRL), the ISS National Lab and National Aeronautics and
Space Administration (NASA). The primary goal of ARISS is to promote
exploration of science, technology, engineering, and mathematics (STEM)
topics by organizing scheduled contacts via amateur radio between crew
members aboard the ISS and students in classrooms or public forms. Before
and during these radio contacts, students, educators, parents, and
communities learn about space, space technologies, and amateur radio. For
more information, see www.ariss.org.

The TNC cannot run FT8 or RTTY, those modes are sound modes and have nothing
to do with packet radio (you need WSJT-X or MMTTY for those). You can do
Amtor and you can connect directly to Winlink or some of the raw packet
programs.

I believe that RTTY is built into the TS-2000, I could be wrong.

The TS-2000 can transmit FSK (RTTY) with outside keying, like the W3YY
FSK/CW Interface or the Timewave Navigator.
