To: info-hams@ucsd.edu

Are your senators and congressman co-sponsors of these bills which are
presently going through the house and the senate?  If not, then write
them a letter!  (And if they are, write them a letter to thank them for
sponsoring the bill which recognizes the amateur radio service as a 
national resource.)

Write your letters today!  (See Jan & Feb 94 QST for more information...
I will try to post some more info soon as well.)

You might be able to get your representative & senators names and addresses
from the blue pages of your phone book.

Ronnie - since you appear to be at Camp Zama, see if you can contact
Roland Cowan there.  He is an accredited VE and is one of the most 
helpful hams I've met.  His callsigns are:  WF4P and 7J1AKI.  He's very
active on both Internet (I'll find his address and advise by separate e-mail)
and packet radio [7J1AKI@7J1AKI.10.JNET1.JPN.AS].   Ask him for information
on TIARA - the Tokyo Int'l Amateur Radio Association as well.  They are a
good group of people.

Subject: Boring WWV Programs
To: info-hams@ucsd.edu

There have been a number of negative comments expressed here concerning the
boring consistency of WWV programming.  Perhaps you all would be interested
in what I will call the WWV Chant.  Some friends and I came up with it way
back when before WWV moved to Colorado.  Unfortunately I can only remember
a few lines ......

                         The WWV Chant
 
                   We're WWV
                     On standard frequency
                   We're on all day,
                     We're on all night.
                   Don't tell us we're wrong
                     We're always right.

I agree.  In other words, it should be easy to design a CW filter with
the narrowest usable bandwidth that has negligible ringing.

Subject: HAM licence and after
To: info-hams@ucsd.edu

Hi all,
I am going to take the Ham test _basic , tomorrow. now i was wondering and want
some advice on what type of radio should i get and what make, what should i be
looking for in a handheld, what price is good for a beginner, etc, after i get my
licence.  i can only work above 30MHz as you all know, so i was thinking of a
dual bander - 2m and 70cm  handheld. is  this a good choice, or what else will
you sugggest. at the moment , more important is the price range i am going to be
loooking at for a reasonable set. 
For the set that you suggest where can i get it in Toronto.

Thanks in advance you your much appreciated advice to this (hopefully) very new
Ham op.

mail me if possible to :

       cs922150@ariel.cs.yorku.ca


Thanks

Subject: Nobel Prize to 2 Hams
To: info-hams@ucsd.edu

The December, 1993, issure of Physics Today, published by the American 
Institute of Physics, has an article about Russell Hulse and Joseph Taylor,
who recently received the Nobel prize in physics for their discovery of
the first binary pulsar. Near the end of the article, Hulse is quoted:
"I came to ham radio by way of radiotelescopes. In Joe's case it was the
other way around."

Interesting, too, was the fact that Hulse "is the fifth graduate of the 
Bronx High School of Science to win the Nobel Prize in Physics."

A local surplus shop, HalTek in Mtn. View, CA has several of these radios, just
came in a few days ago.  They look very incomplete, but if someone's interested
they might be chock full of difficult to get parts.  I don't work for them, 
just a frequent customer.

NOTES:
       Predicted geomagnetic activity is based heavily on recurrent
phenomena. Transient energetic solar events cannot be predicted reliably over
periods in excess of several days.  Hence, there may be some deviations from
the predictions due to the unpredictable transient solar component.

NOTES:
     The 10.7 cm solar radio flux is plotted from data reported
     by the Penticton Radio Observatory (formerly the ARO from
     Ottawa).  High solar flux levels denote higher levels of
     activity and a greater number of sunspot groups on the Sun.
     The 90-day mean solar flux graph is charted from the 90-day
     mean of the 10.7 cm solar radio flux.

NOTES:
      These VHF DX prediction charts are defined for the 30 MHz to 220 MHz
bands.  They are based primarily on phenomena which can affect VHF DX
propagation globally.  They should be used only as a guide to potential
DX conditions on VHF bands.  Latitudinal boundaries are the same as those for
the HF predictions charts.
