- Subject: CW filters and DSP-9
- To: info-hams@ucsd.edu
-
- According to the discussion below and previous postings, I want to
- supply some calcualtions shown in two pictures in following postings
- based on a Fourier analysis of a morse signal of 10 times 'e':
- 00000101010101010101010100000
-
- For that, I assumed a period of 120 ms for one dot, which needs two time
- units of 60 ms: '10'
- (50 time units per word, e.g.'paris', 20 wpm -> 60 ms per unit)
-
- The first picture will show the frequency spectrum for that morse pattern.
- ('morse1.jpg', uuencoded, size: 72833 kB)
-
- The second diagram will show the morse signals after passing filters
- with different cut-off frequencies: 25 Hz, 50 Hz, 125 Hz, 250 Hz;
- These frequencies apply to one sideband, so the filter bandwidth for
- the whole signal is twice the frequency according to two sidebands,
- respectively. For the filter, a flat passband and perfect
- cutting off is assumed. The calculation is just the Fourier sum of the
- peak frequencies obtained from the spectrum in picture 1.
- Here you can see one possible reason for the ringing of narrow filters
- which cut off the higher frequency components of a signal.
- The lower the cut-off frequency, the wavier is the signal.
- Modulated with 700 Hz, you'll get your ring ;^)
- ('morse2.jpg', uuencoded, size: 61701 kB)
-
- Further you can see, how the rise times are affected by the
- filter bandwidths. The cut-off frequency determines the
- shortest possible rise time for the signal. So, the narrower
- your filter is, the mushier are the dits.

- I believe you are thinking of a store that used to be in Leesburg, VA.
- They closed about a year ago. Sold most of their stuff to G and G
- Electronics in Gathersburg, MD. (phone 301-258-7373). I heard the owner
- of the Leesburg store may still be doing some business from his home.
- You might call G&G for more info, or G&G might have what you need, the
- store looks like one fine junkbox.

- Subject: Online Repeater Database Helper Program
- To: info-hams@ucsd.edu
-
- I have written a program to make it easier to enter data into
- the Online Repeater Database devised and managed by Conway Yee
- ( yee@mipg.upenn.edu). He is looking for volunteers to enter
- the information available publicly from several sources.
-
- If you are right now, or were seriously contemplating doing
- some of this work, and are interested, you may email me about
- the program. I would like to have a few people try it out. If
- it seems appropriate, it might be possible to have it available
- by ftp somewhere. For the moment, copies will be distributed
- by uuencode.
-
- What follows is an excerpt from Conway's last message about the
- status of the project. (SInce this message, I've done MA and OR
- with 1991 data.) :
-
- ----------------------------------------------------------------
- This version 0.02 (last updated 19940120) of an online repeater
- directory which currently contains over 1800 entries. All previous
- versions are obsolete.
-
- There are entries for AK, CT, DC, DE, HI, ID, KY, ME, MT, NC, ND,
- NH, NJ, NV, NY, PA, RI, SD, UT, VT, WV, WY. Since the last time
- this data base was posted, I have added one state and two
- volunteers have added four more.
-
- Thus far, people have volunteered for
- 1) AZ
- 2) KY, MS, SC, TN, VI, WV, GA (two states already done
- but the current data will be replaced with up to date
- information).
- If everybody follows through with their intentions, we will
- soon have over half the United States accounted for.
-
- This file with all the data is be available for anonymous ftp as
- mipg.upenn.edu:/pub/yee/rptr002.Z

- Subject: Quake Alert via Amateur Radio
- To: info-hams@ucsd.edu
-
- I thought people in these newsgroups would find this info to be of
- interest.
-
- In a post from another newsgroup someone said:
-
- "A recent posting made mention of a "Quake Awake" device which warns of
- P-waves which preceed S-waves in a quake. Can anyone give me more
- information on this device?"
-
- And someone else said:
-
- "I bought two "Quake Awakes" after Loma Prieta. Not because I thought
- they would be particularly useful as a warning device, but because I
- found the concept interesting. Subsequent postings to the net
- ndicated that they were not particularly reliable, but since we ave
- had *no* noticeable quakes in the last four years, I have no mpirical
- evidence :-(."
-
- And finally I said:
-
- "Better yet, if you are a amateur radio operator or have a scanner,
- you may be interested in a SEISMIC DETECTOR on frequency 445.400 MHz.
-
- Someone has a seismometer interfaced to a radio transmitter. Perhaps
- it is the USGS. I just don't know. Anyway, this unit probably picks
- up P waves (and maybe S waves) from a seismometer somewhere in the
- mountains in the Los Angeles basin. The transmitter sends out a tone
- on some secret frequency. Maybe it is not so secret, but, I don't
- remember it.
-
- Anyway, the ALERT group knows the frequency regenerates the signal and
- pipes it via landline to one of its repeaters on Easter Hill (My note:
- located in the hills of Orange, CA). We get a 8-14 second warning
- before aftershocks generated from the Northridge sequence. Events
- from Landers take about 10-15 seconds and those from Big Bear take
- about 7-10 seconds. The detector picks up events from afar if they
- are strong enough. It even picked up events in Oregon last year.
-
- Here is info from one of the bulletins sent to ALERT members.
-
-
- SEISMIC DETECTOR WORKING WELL
-
- The new seismic detector on the 445.400 MHz repeater continues to work
- great. A 186.2 Hz CTCSS tone will be heard over the repeater during
- earthquake events. To use this new feature set your radio frequency
- to 445.400 MHz and your PL to 186.2 Hz decode (stored this into an
- extra memory slot for easy access). Whenever an event occurs your
- radio will pass the earthquake warning tones but normal conversation
- on the repeater will be muted. This great new feature allows your
- radio to stay on all night in a mute mode. Please remember when you
- hear the earthquake tones coming through the 445.500 MHz Easter Hill
- repeater we ask all members to stop QSO's and stand by until the
- warning tones stop coming through the link. This allows all members
- to get a bearing on where the earthquake activity might be. This
- seismic tone will continue to be TESTED at 9:00 PM every Monday and
- once again at the conclusion of the Net around 9:25 PM. Thanks Gary -
- WA6SUL for maintaining this important ALERT system feature.
-
- Note: ALERT means Amateur Licensed Emergency Response Team (I think)."

- Subject: Voice of America News Now Available on Internet
- To: info-hams@ucsd.edu
-
- The Voice of America's international News and English Broadcasts radio
- newswire is now available via anonymous FTP and the Internet Gopher,
- along with a variety of other information from VOA and Worldnet
- Television.
-
- The News and English Broadcasts wire service includes the texts, in
- English, of radio reports prepared by VOA staff correspondents, contract
- news reporters ("stringers"), and feature and documentary writers. The
- wire provides a comprehensive daily report of news events, worldwide.
- It is one of the core news products of the Voice of America, and is used
- as the basis for much of VOA's programming in all languages. The public
- Internet server is updated within a few minutes of the issuance of each
- report by the VOA central news department; a seven-day archive of the
- wire is available on the public server.
-
- In accordance with U.S. law, program materials such as the News and
- English Broadcasts newswire are provided exclusively for recipients
- outside the United States.
-
- Selected VOA and Worldnet program schedules, shortwave radio frequency
- and satellite downlink information, public announcements from the Voice
- of America and Worldnet, and technical documents on international radio
- and television broadcasting are also available on the public Internet
- server.
-
- All the materials on the server are available by anonymous FTP and the
- Internet Gopher. Schedules and other general information materials may
- also be requested via electronic mail; the News and English Broadcasts
- newswire is not available via email because its contents change so
- rapidly.
-
- The Voice of America and Worldnet are, respectively, the international
- radio and television networks of the United States Information Agency,
- and operate out of headquarters in Washington, D.C. VOA has news
- bureaus in many major world cities.

- Hello Andy:
-
- I am not sure what you mean by "less than ideal antenna" if you exclude
- dipole. The dipole is the basic antenna for me, and I use QRP, mainly
- SSB, sometimes CW, and almost always on 40 meters. Do you intend to
- use a quarter wave vertical? A mobile whip?
-
- It is really hard to predict what sort of experience you will have with
- QRP from your QTH. Really hard. I have had a lot of luck, even with
- a mobile whip on the car using QRP. You muse realistic, but also
- know that things can happen with QRP that others just won't beleve.
- I have worked a LOT of DX on 40 SSB with 5 watts and a dipole. A LOT.
- But this is by patient working and late late nights and stalking guys
- and things like that. Other times it has actually been easy. There are
- even a few hams locally who run 100 watts with other dipoles and verticals
- and on occasion, I get as good a signal report as they do, even when I
- ask for a real one.
-
- 40 CW is really interesting. The antenna is the key, not really the power.
- 5 watts is plenty for most contacts under a lot of circumstances. My only
- advice to you is to very carefully consider the sort of antenna you will
- use. A good dipole, even shortened, up 20 feet or more should be fin.
- A 50 foot long wire made of invisibly thin wire thrown into a tree or over
- a roof will work fine also. Good luck.
