- Subject: CFV: sci.geo.satellite-nav
- To: info-hams@ucsd.edu
-
- FIRST CALL FOR VOTES (of 2)
- unmoderated group sci.geo.satellite-nav
-
- Newsgroups line:
- sci.geo.satellite-nav Satellite navigation systems, especially GPS.
-
- Votes must be received by 23:59:59 UTC, 8 March 1994.
-
- After this CFV appears on news.announce.newgroups, it will be posted
- to the GPS Digest <gps-request@tws4.si.com>.
-
- This vote is being conducted by a neutral third party. For voting
- questions only contact rdippold@qualcomm.com. For questions about the
- proposed group contact Andy Arkusinski <arkusinski_andy@si.com>.
-
-
- CHARTER
-
- This will be an unmoderated newsgroup.
-
- SCI.GEO.SATELLITE-NAV was chosen because the focus of this group is on
- navigation. The SCI.SPACE hierarchy deals with various aspects of
- space exploration and use, but this newsgroup deals mostly with
- terrestrial applications. The fact that the space segment is in space
- is almost incidental to the focus of the newsgroup.
-
- SCI.GEO.SATELLITE-NAV will allow a centralized location for discussion
- of global navigation satellite systems (GNSS). The charter
- specifically includes the US Global Positioning System (GPS) and
- Russian GLONASS, but is also open to discussion of other existing and
- future satellite positioning systems.
-
- Some topics that fall under this newsgroup charter are:
- * Technical aspects of GNSS operation.
- * User experiences in the use of GNSS.
- * Information regarding GNSS products.
- * Discussion of GNSS policy (such as GPS
- selective availability).
- * Extensions to basic GNSS technology, such as
- differential GPS and pseudolites.
- * Navigational uses of satellite systems whose primary
- purpose is not navigation, such as a communication
- satellite net.
-
- Examples of topics that would not fall under the group charter are:
- * Other satellite systems such as communications and
- intelligence gathering, except for navigational uses of
- such systems.
- * Discussion of space policy in general.
- * Discussion of areas that may use GNSS, such as
- surveying, sailing, or aeronautics, except as they
- directly relate to use of GNSS.
-
- GPS, in particular, has turned out to be a technology with a great
- deal of synergism with many fields. GPS is used, not only for
- military positioning which was the original purpose, but in
- applications as diverse as entomology and film making. A major intent
- of this newsgroup is to share the uses to which GNSS technology is
- being put, thus inspiring even more innovative uses.
-
- While part of the SCI.GEO hierarchy, this newsgroup does not exclude
- non-terrestrial uses of satellite navigation. Use of GPS to determine
- space vehicle position is within the charter.
-
- This group is also intended to function as a resource for newcomers,
- who can post their questions and receive help from others who have
- passed that way before.
-
- Rationale: There is no single newsgroup where information on GPS and
- other satellite navigation systems can be found. Questions are often
- posted in newsgroups such as sci.electronics, rec.aviation, and
- sci.aeronautics. To address this lack, the mailing list GPS Digest
- was started about a year ago, and now has over 400 subscribers.
-
- Recently we attempted to convert GPS Digest from a moderated weekly
- newsletter to an unmoderated reflector. Submissions, which had been
- running at 2-3 per week, immediately picked up to 15 the first day.
- Our resources were overloaded, and the Digest is back to the original
- format. Many readers indicated the real-time response was helpful and
- suggested the formation of a newsgroup.
-
- The RFD and CFV will be posted to the GPS Digest mailing list as well
- as Usenet newsgroups. Only those readers with access to Usenet should
- cast votes (for or against) formation of the newsgroup.
-
-
- HOW TO VOTE
-
- Send MAIL to: voting@qualcomm.com
- Just Replying should work if you are not reading this on a mailing list.
-
- Your mail message should contain one of the following statements:
- I vote YES on sci.geo.satellite-nav
- I vote NO on sci.geo.satellite-nav
-
- You may also ABSTAIN in place of YES/NO - this will not affect the outcome.
- Anything else may be rejected by the automatic vote counting program. The
- votetaker will respond to your received ballots with a personal acknowledge-
- ment by mail - if you do not receive one within several days, try again.
- It's your responsibility to make sure your vote is registered correctly.
-
- Only one vote per person and per account will be counted. Addresses and
- votes of all voters will be published in the final voting results list.

- SYNOPSIS OF ACT
- --------------------
-
- Solar activity was low. Two C1 x-ray events were
- observed this period; the first was correlated with a SF flare
- from Region 7668 (N08W17) with a maximum at 12/2346. Since the
- flare, 7668 has shown some decay, particularily in the trailer
- portion of the group. The second C1 event began at 13/0051Z,
- maxed at 13/0244Z and finally ended at 13/0429Z. It was
- optically uncorrelated. Culgoora reported a Type IV sweep with
- start and end times at 13/0159Z and 13/0234Z respectively. One
- new region was numbered this period -- Rgn 7671 (N11E75).
-
- Solar activity forecast: solar activity is expected to be
- low. Rgn 7668 and Region complex 7670 (N09E60) and rgn 7671
- all have the potential to produce C-class activity.
-
- At middle latitudes, the geomagnetic field has been mostly
- unsettled to active with some minor storm conditions reported
- during the past 24 hours. High latituds conditions have been
- at mostly unsettled to minor storm levels with some stations
- reporting major to severe storm conditions.
-
- Geophysical activity forecast: the geomagnetic field is
- expected to persist at mostly unsettled to active levels with
- periods of minor to major storm conditions likely. Conditions
- are expected to moderate to mostly unsettled on day three of the
- forecast period.

- B. High Latitudes
- Active 40/30/25
- Minor Storm 25/10/10
- Major-Severe Storm 10/05/01
-
- HF propagation conditions persisted below-normal over all
- regions. Hardest hit continue to be the upper middle to polar
- latitudes where occasional near-useless propagation conditions
- have existed at some times of the day. No significant changes
- are expected over the next 72 hours, although a very gradual
- trend toward improving conditions is expected, particularly
- after approximately 15 or 16 February. High latitudes will
- require several additional days to recover from this rather
- influential disturbance.

- On the subject of nicads, I have been reading all the magazine articles,

-
- : Two rules for long NiCd life: don't overheat them by overcharging; don't

-

- has discharged more than the others. To prevent cell reversal, always
- recharge such a battery pack before using.

- A comment on the TH78A. I think it is a great radio with the following
- exceptions: 1: Cannot be used on external antenna on 2M due to horriffic
- intermod problems.
- 2: The battery release latch will occasionally trip when wearing

- Wow, Aaron! You must grow some big watts in your neck of the woods.
-
- Seriously, you are better off using a large capacity heat source, such
- as the 250+ watt gun, because the longer you keep that heat on the
- connector, the more likely it is that the center conductor will
- migrate. My technique is to get it hot, melt the solder, and get it
- cooled down, as quickly as practical. By the way, if you use cheap
- connectors, you will also notice that the insulator that holds the
- center pin will melt and the pin will sag. Use Amphenol. Hold the
- cable and connector still until the end of the cable is cooled so the
- center won't migrate. Scotchkote, tape, and more Scotchkote to seal
- for outside connections.

- Subject: which is better qrp band--30 or 40?
- To: info-hams@ucsd.edu
-
- You will be much better off by using 30m for followin reasons.
-
- 40 is segmentaized e.m. different ITU zones can operate only on certain
- freq. or segments of the 40m band.
- 40 has Broadcasts and other QRM working against QRP.
- On 40 "other" station can use 1KW so ham to ham QRM is a factor.
-
- 30 is 'NEW' and same freq. for all ITU.
- Very little QRM
- On the edge of muf
- Max power is 100w
- Beam fix or rotatebl is feasable and in my opinion a must for QRP.
-
- Try it you may like it!!!!!
