-
- ...I've modified my Icon 271E for 9600 (also an MFJ TNC/modem). As I
- recall the signal injection point I used was the wiper of the audio
- level pot leading to the varactor. There is a blocking cap on this line
- already. I fed my sig thru a non-polarized 1mmf cap and a 1K resistor.
-
- The "conventional wisdom" scheme is to connect through a cap & 10K resistor
- to the varactor - but this does not seem to work.
-
- By the by - the circuit in this area is the same in several Icom radios,
- the IC-290 and IC-490 being among them.

- New Landline BBS Provides STS-59 SAREX Information
-
- The Johnson Space Center Amateur Radio Club has set up a telephone computer
- bulletin board (BBS). The purpose of the BBS is to provide a source of
- current Space Shuttle mission Keplerian Elements.
-
- There are limited number of BBS files available for downloading. Among the
- current files are:
-
- o Current and old element sets for the mission in progress
- o Current mission information
- o Shuttle Amateur Radio Experiment (SAREX) information
- o Recent Space Shuttle Mission Schedules and Manifests
- o Astronaut/Cosmonaut Ham List
- o Current JSC Amateur Radio Club Newsletter
-
- We ask that no files be uploaded to the BBS. The telephone number is
- (713) 244-5625. Our modem can handle all bauds up to and including 9600
- baud. The parameters are N-8-1.
-
- The BBS is currently running in ProComm HOST mode, so the logon is very
- simple and downloading is easy. After logging in, you will see the
- Welcome Screen describing the BBS. Also, the Welcome Screen contains the
- current and latest element set number (e.g., JSC008) loaded on the BBS.
- Check it against your last set so you won't waste your time duplicating a
- set you already have. Press ENTER to bring up the second page containing
- the current Space Shuttle Keplerian Element Set. If you have a file cap-
- ture or screen capture function in your communications software, then you
- should use it for this page. That way, you won't have to go through the
- file download process if all you wanted was the latest element set. If
- you have any comments for the Club or BBS sysop, leave a message and we
- will respond.

- CT1ERC Reports POSAT-1 Voice Contacts Made
-
- CT1ERC reports that a special event amateur satellite station, CU2APO, was
- setup on the island of San Miguel in the AZORES for a technical exhibition
- to a youth grounp using POSAT-1. This demonstration was arranged by the
- PoSAT Consortium in which they agree to switch the satellite to operate on
- the amateur frequencies and it was configured as a FM transponder for a
- single pass to allow voice contacts between this island in the middle of
- the Atlantic ocean and the continent. Everything was arranged overnight
- and on short notice so unfotunately there was not enough time to send out
- notices of this event for other radio amateurs to participate. However,
- CT1ERC wishes to pass allong his report of the this first time voice
- contact on POSAT-1.
-
- "The uplink frequency was 145.975 MHz and the downlink frequency was
- 435.275 MHz which by coincidence is a frequency with alot of strong QRM at
- CT1ERC's QTH. At 12:28 UTC 24-FEB-1994, with the satellite heading from
- North, the mutual window between CT1ERC's station (located in the extreme
- North of Portugal) and CU2APO (located in the extreme West, half way to N.
- America) opened and he exchanged a QSO with Pedro Carvalho (CT1DBS). The
- reports were both S59 but only for short periods, due to the strong bursts
- of QRM which made communication very difficult. One minute later there
- appeared Miguel Gomes (CT1EVH) operating the club station CS1APO located in
- Lisbon and Artur Gomes (CT1DIA) located in Faro (extreme South of Por-
- tugal). The QRM affected all stations except CT1DIA who have copy all of
- us during the whole pass with reports between S57 and S59. Sometimes
- during the pass two Spanish stations, apparently mobile, in a QSO on the
- VHF band were completly unaware that they were using a satellite uplink and
- reaching the downlink with S55 to S57."
-
- CT1ERC wants to thank to the the Consortium for made the satellite avail-
- able for 10 minutes and to Pedro, CT1DBS, for all his efforts and hours
- spent in convencing the POSAT Consortium to allow this demonstation to
- happen.

-
- It occurs to me that a particular Newsgroup should pertain to a specific topic.
- Not a jumble of as many things as can be stuffed into it. That is the obvious
- intention of having so MANY different, and exciting newgroups to choose from.
-
- Although "Cross Posting" as you call it, may not incur additional "bandwidth"
- in posting the original article, it certainly does increase the size of each
- newsgroups dumped message. Since I am using UUCP which costs me .10 Cents
- a minute to retrieve my newsgroups, it's even more annoying to find that I'm
- getting mutlipule copies of material I am not even remotely interested in
- being placed along-side info that I am very much interested in, simply because
- it is remotely connected to Ham-Radio. I would not fault the newgroups
- themselves as much as I would the person or group that was doing the posting.
-
- That sorta shoots the who Idea of having so MANY newsgroups in the foot
- doesn't it?
-
- If I subscribe to several different newsgroups all pertaining to HAM-RADIO
- in General, I don't expect to see the same posting on each newsgroup. If there
- were a few General Coverage Newsgroups I might expect it, but not on different
- HAM-RADIO areas, like "space", or "digital", etc... I don't expect to see
- DX Info in either of them. In actuality I would be annoyed by finding
- DX news in a Ham-Digital newsgroup.
-
- It's seems to me that it does cause an increase in what it costs to operate
- my UUCP system, if someone is posting multipule copies of news to several
- individual newsgroups which I subscribe to. And I am only on such operator.
- I am sure there are hundreds, or thousands just like me all around the world.

-
- Ah, but it DOES take extra bandwidth to send them to my system from the
- news-server. It takes my system extra time, and cost to download the
- same FAQ, or whatever, over a UUCP connection. Storage? I can dump
- the message once it's here, but I can't stop it on it's way if I don't
- know its coming down the line.
-
- I am just a small operator of a UUCP to TCP/IP Lan. So if you sent a 1mg
- file to more than one newsgroup I subscribe to, you are seriously cutting
- into my budget.
-
- Seems to me that common sense would dictate that you would only forward
- such material to one newsgroup, and store the FAQ at a well known
- 'anonymous' access site for folks to pick up at will.
-
- Just my two cents worth after watching this message get larger, and longer.

- 1. You would think that the first cell site to pick up your signal would
- carry it on as far as it could, right? I do see how reaching many at once
- would pose a problem, but, what about 2. areas where you're in your car and
- you're in an area where two cells overlap? That does happen, especially here
- in Alabama where the hills are just large enough to wreak havoc on anything
- over 400Mhz... But, back to the second part: How would cell phones or sites
- know which site would carry the phone? I don't see how both would as this
- would interject other problems which I don't want to get into. The answer to
- the problem lies in that second part. The only difference in two overlapping
- on the road and 50+ overlapping in the air is that that one cell that picks
- your signal up can carry it a lot longer distance... I see how this could
- cause other problems, though. What about a preson on another cell 20 miles
- away, who's on the same frequency? You're up high enough to reach it, and it
- you, so...?

- Now that the repeater project is back on track (I hope), I am asking

- What's so odd about that? Are you confusing full scale with full

- I think you are forgetting WWV's mission: they are not out to work DX,
- they are trying to provide the maximum coverage to the maximum number of
- people. For this, a half-wave vertical dipole is an excellent antenna.
- It has a mix of high and low angle radiation and everything in between.
- It's the same reason you wouldn't use a beam while conducting a local
- net - you need to talk to everybody. A certain amount of phasing has
- been used probably to overcome their location at the foot of the
- Rockies (just a guess).
-
- Incidentally, there is no such thing as an "antenna with more gain which
- would give the same radiation pattern". Can't happen. Antenna gain is
- created by intentionally distorting the radiation pattern and/or angle
- in the favored direction. You can't get something for nothing.
