- Subject: 2nd Floor Ground or No Ground?
-
- I've recently moved into a new house, and my shack is now on the 2nd
- floor. This new location has provided me with few questions, one of
- which includes the ground for my rigs and antenna.
-
- Some folks say to keep a ground, even though the ground might be as long
- as 40 feet. Others say to do without a ground completely.
-
- Still others suggest using the existing ground that is used in the
- house's electrical system. To confuse things further, I've also seen the
- artificial grounds that are advertised in catalogs (MFJs, for instance).
-
- So, what to do? What options do I actually have? What are others
- on the 2nd floor doing? Any suggestions would be appreciated.

-
- The VCR has a PLL circuit working at 14.318 MHz (4 times subcarrier).
- Your transmissions are disturbing the PLL and causing the master
- oscillator to be pulled far enough off frequency to affect tracking.
- This will cause the motor speed to change as the servo tries to
- compensate, and the tension sensor to detect excess (or slack)
- tape tension and automatically shut down the machine. Better shielding,
- and moving the antenna further away, should reduce or eliminate the
- problem.

- Subject: Lightning protection advice needed!!!
-
- I'm looking for some advice that anyone can offer on how I might protect
- my tower-mounted wind sensors from lightning damage. I've posted this on
- sci.geo.meteorology, but who knows more about electronic equipment on towers
- than a ham?
-
- Here's the situation. The cup generator for the anemometer and the
- electrical distributor for the wind vane are mounted on a 64-ft free-standing
- metal tower in order to get them above the trees nearby. Thunderstorms are
- quite common in my area, and I have mounted these sensors a foot to each side
- and 3 feet from the top of an 8-ft aluminum mast in hopes that the solid tip of
- the mast would receive any lightning that struck the tower. The tower is well
- grounded with a 4-gauge braided copper cable connected to an 8-ft copper
- grounding rod. Yet, in 2 years of operation I've had three instances of
- lightning damage to the sensors and indoor display. The connections from the
- junction box at the tower base to the sensors at the top are made with a 7-wire
- bundle of solid 18-gauge individually-insulated copper wires. This wire bundle
- is plastic covered, but it is not electromagnetically shielded. Is it possible
- that the lightning discharge through the tower is inducing a damaging current
- in these wires? The 200-ft run from the tower to my house is made with 50-wire
- 24-gauge telephone cable (2 wires per circuit, 36 spares) and is buried from 6
- to 12 inches deep inside a plastic conduit. Can this buried cable be affected
- by ground currents from the lightning discharge? The wind direction lights on
- the indoor display are powered by an external step-down AC transformer plugged
- into a regular 120 Volt outlet. This transformer has also been damaged each
- time, but none of the other appliances on the same house circuit have been
- damaged, so I don't think the jolt is coming from the 120 V supply.
-
- I'd appreciate any advice from you radio folks out there. I'll try
- anything not too expensive or ridiculous, including grounded conduit on the
- tower or spiritual incantations. Thanks in advance.

- Subject: Scouting on the Net during JOTA (World Jamboree On The Air)
-
- Here are the side events to the Worldwide Jamboree on the Air,
- which will be held on October 15-16 on the amateur radio
- frequencies worldwide. More details on JOTA 94 and the frequencies
- used can be found on ftp.ethz.ch in the directory
- rec.scouting/worldwide.
-
- (Note: this is an extract of the upcoming release of rec.scouting
- FAQ#2 on worldwide scouting. Since JOTA is so close, I decided not
- to wait until the normally scheduled posting)
-
- At this time, I've received the announcements for three Internet
- Happenings to be held during JOTA 94 (October 15-16):
-
- A. JAMBOREE ON THE IRC (JOTIRC)
-
- IRC stands for Internet Relay Chat. IRC is devoted to just "type-talking"
- with other users around the world. You join what they call a channel
- (similar to AOL's rooms, if you're familiar) and type words which appear on
- the channel. Everyone on that channel receives your words and can respond.
- The software needed is basically a client. Clients can be obtained from many
- ftp sites. See Scott Yanoff's "Internet Services" list on
- alt.internet.services for public IRC clients, or find out if your own system
- has the client installed by typing the following from your UNIX prompt:
-
- irc
- /join #scouting
-
- For more information on IRC, anonymous FTP to:
- cs.bu.edu:/irc/support/tutorial*
-
- One of the permanent channels on IRC is #scouting, which will be the
- central meeting point for JOTIRC participants.
-
-
- B. CIBER CAMPAMENT
-
- The mexican scouts have set up a local chat server called "Ciber
- Campament". While it is set up for JOTA 94, the server is already up
- and running today.
-
- To connect, telnet to 129.108.3.7 on port 7777 (type
- 'telnet 129.108.3.7 7777' from your UNIX or PC host, or use NCSA
- Telnet from a Macintosh). You can log in with any alias and any
- password.
-
-
- C. E-MAIL JOTA 94
-
- Mosman District Scouts, located in Sydney Australia, invite you and
- the girls and boys in your Scout/Guide unit to participate in EMAIL
- JOTA'94.
-
- At 1st Balmoral Sea Scout Hall Mosman District Scouts, Guides,
- Brownies, Cubs, Rovers, Rangers, Venturers and their Leaders will be
- broadcasting on 2 or 3 amateur radio rigs provided by alocal radio
- club. There will also be a dial-up phone link between a UNIX
- computer called 'scoutnet', and a commercial UNIX email service
- connected to the Internet.
-
- In the weeks leading up to JOTA which happens worldwide on during
- October Scouts and Guides will be able to use the email service to
- pre-arrange times and frequencies for radio contact with other
- Scouts/Guides.
-
- For more information on this event or to get in contact with 1st
- Balmoral, contact John Young at yo@sydney.sgi.com.

- Actually, in dense metro areas, it is often best to use a very high
- gain, narrow beamwidth, antenna and an attenuator. That's because the
- sharp antenna can be rotated to minimize multipath. Using just a dipole
- or rabbit ears, you're likely to have severe ghosting.

- Actually, yes. When you "kerchunk" the repeater, you're

- Very good. Your audience was perfect - they already understood our value!
- This is not what I am talking about, that is not the place where people will
- laugh at you. There are many communities where this is just NOT so.

- Well, unfortunately, I am usually addressing the local Planning Commission,
- too. And, there are not the well integrated RACES programs going on in
- most communities I have worked in. And, my presentation is very good,
- usually bolstered by some ARRL person (last time by our Vice Director
- here) who can speak directly to the issues with personal experience.
- This does not always do it. Not in our local communities.
-
- The point I am trying to make is that we, as hams, do not have a special
- place in the hearts and minds of the general population - and that we must
- understand that, and treat the general public with respect for their
- opinions, yet we must help to show the true value of ham radio to those
- who might understand. This is very important, especially with the
- current commercial pressure to take over some of our spectrum - there
- is no constitutional right to ham radio. There is no constitutional right
- to have an antenna. If, tomorrow, congress decided that ham radio was not
- a valuable public resource (look at the other silly things they do :-)
- - we would be past history in a minute.
-
- That is my point. It is not to our benefit to take the "we have rights -
- we're the best even if you don't believe it" approach here. We could lose.
- We need to be constantly aware of the reality that the general population
- does not necessarily see ham radio as a valued national resource - and I
- believe we need to work, little by little, to change that and show our
- value to the community.
