i use an old rca vcr whose video head is bad... it has a 7 day timer...
i used it to capture weather satellite audio during the times i
couldn't be at the computer... the specs on the audio channel
are fantastic... cd quality... my unit has audio agc and manual
input level adjustment for each audio channel... check with a
vcr repair shop... they usually have a few old units lying
around whose video heads are bad consequently they are not
worth fixing... i got my unit for free that way...

ZIA-link does get into Phoenix. However, it is not always "up." Lately,
it seems to be down more often, at least here in Arizona. ZIA covers the
southwest from California through Arizona and New Mexico to West Texas.
It seems pieces are up but not necessarily all the links.
I'm afraid I can't help you with Northlink.

Completely, totally, absolutely, INCORRECT. But thanks for playing!
How could SWR and PF be the same? SWR *cannot* be less than 1.000:1, while
PF *cannot* be greater than 1.000. Further, your assertion tha SWR is
somehow related to voltage vs. current phase would imply that it is impossible
to acheive other than a perfect 1:1 SWR with a purely resistive load, which
is most definitely not the case.
I'd go ahead and post the real definition of SWR, but I see that this has
already been done MUCH earlier.

How to find the Rec.radio.amateur.misc Frequently Asked Questions list
------------------------------------------------------------------------------
This article will tell you how to find the answers to frequently-asked
Questions (FAQ) from rec.radio.amateur.misc. The FAQ articles are posted on
the 7th of each month. This article is posted on the 14th, 21st, and 28th of
every month as a reminder of where to find the FAQ.
The FAQ articles are intended to summarize some common questions on the
rec.radio.amateur.misc newsgroup and Info-Hams mail list as well as to help
beginners get started.
Besides the monthly posting, the FAQ is always available via anonymous FTP
and from e-mail servers. This article contains instructions for obtaining a
copy of the FAQ. It also contains the table of contents from the FAQ so
that you know which questions are covered by it.
Please provide a copy of the FAQ to any new or soon-to-be Hams you know.
Regular FAQ postings can help save network bandwidth and maintain a good
signal-to-noise ratio in the newsgroup. However, they can't do it alone - you,
the reader, have to use them. If you are a new user, please print and review
the FAQ articles and look at the instructions in the news.newusers newsgroup
before posting any articles. If you are an experienced user, please help by
refraining from answering frequently-asked questions on the newsgroup if they
are already answered by the FAQ articles. Instead, send e-mail to the user who
asked the question. (It will be helpful if you include the part of the FAQ
that answers their question, but not the whole thing.)
--How to obtain a current copy of the FAQ-------------------------------------
There are 3 ways to obtain a copy of the FAQ.
1) NetNews
2) Anonymous FTP
3) An Electronic Mail Server
Option #1: NetNews
------------------
If you are familiar enough with NetNews to look through previous articles on
your system, Option #1 above may be the easiest for you. The FAQ is posted
so that it should not expire from your site's news spool until the next one is
posted. Unfortunately, some news administrators do not honor the expiration
dates meant to preserve the FAQ.
Look in rec.radio.amateur.misc, rec.radio.info, rec.answers, or news.answers.
If the FAQ has expired at your site, try Option #2 (and ask your news
administrator to honor expiration dates for articles cross-posted to
news.answers if he/she can.)
Option #2: Anonymous FTP
------------------------
Anonymous FTP uses the File Transfer Protocol. It is only available to sites
which are directly connected to the Internet. If you don't know how to use
FTP and can't find a friend to help you, continue to Option #3. If your site
is not connected to the Internet, you should also continue to Option #3.
The following sites have copies of the FAQ:

Option #3: Electronic Mail Server
---------------------------------
If you can't use Options 1 or 2, your only remaining option is electronic mail.
You can retreive a copy of the FAQ by sending a message to
mail-server@rtfm.mit.edu
The body of your mail will contain a command for the mail server software.
To get all of the FAQ (consisting of 70K of e-mail in 3 parts), place the

As at least one other person has said, you don't have to go out and buy
the most expensive HF rig you see. :-) In fact, there's nothing that
says you even have to buy a brand-new rig. My first HF rig was an old
Galaxy V Mk 3. Here's the story.....
I was home for vacation (Christmas break, in fact) from school, and one
of the local hams (this was in San Antonio) heard that I was looking to
upgrade to general (I was a tech), but that I didn't have an HF rig. He
found out about this because I asked about details on where to either get
a very inexpensive rig or get help building one. He wasn't too happy
about the fact that I didn't have a rig, so he set out to ``solve'' this
``problem''. :-) Within 10 minutes, he'd found two people willing to
donate gear. The first person who responded said he had an old military
receiver that would at least get me started. The second person said that
was nice, but he had an old Galaxy V that he'd sell to me for 25 cents.
So I ``bought'' a Galaxy V Mk 3 for 25 cents (he could then tell his
wife, ``yes, dear, I *SOLD* it!''). The only condition on that sale
was that when I was done with the rig, I either return it to him, or
preferably, pass it on to another new ham. You guessed it...I ``sold''
it for 25 cents. :-) And, of course, the same conditions applied
there, too---he's going to eventually ``sell'' it...for 25 cents.
Now, this may sound like an extreme example, but there are lots of old
tube rigs out there, many of which are in pretty good shape. In fact,
there are some tube rigs that I wouldn't mind having right now. I have
a Kenwood TS-140S---it's a good rig, but somehow the old Collins and
Drake rigs I remember using just, well, out-did it...don't ask me to
explain it, because I can't. The same could be said for an old Heathkit
HW-101 that I played with at one point (a friend from school and I made
a temporary trade just to try the other's rig out...the day I had to
give that HW-101 back was a dismal day). It was as stable as any synth
rig I've seen, and the audio quality, both xmit and rcv, was out of this
world. I don't know if this applies to all of the 101s, but it certainly
did for that one!
Look around. ASK AROUND! Let people know that you're looking for a rig
that fits in with a college student's budget (i.e., it's virtually free),
and that you just want to get on the air. Someone should be able to
help you out.
Oh, one last point. Don't expect to get all sorts of fancy filtering from
an old, inexpensive tube rig. Don't worry about it, either. First, your
ears will develop to the point where you'll be able to pick out even the
weakest sigs from the noise (I got really good at this, and when I'd go to
the Texas A&M club station, W5AC, I'd easily work people who others in the
shack couldn't even hear at all, even with all of the fancy filtering on
the TS-930 that was there at the time). Second, you can always build your
own filters and add them as outboard units. Op amps are dirt-cheap, and a
+12/-12 VDC power supply isn't *THAT* expensive to build, either.... Just
be careful about the voltage levels going to the (external) speaker on the
tube rigs---you may need to add some level conversions (I did with the
Galaxy).

Sorry if this is a bit terse---there's a thunderstorm on its way, and here
on the island, we have power failures every time the wind blows...not to
mention thunderstorms. I've got to be shutdown when the power starts to
fluctuate..... (No, I can't afford a UPS yet, even at $100 US.)

HF is *NOT* dead as far as new technology is concerned. The directions
have just changed a bit, that's all. If you look at the world of small
(i.e., apartment-sized) antennas, for example, you'll see that there's
a lot of room for experimenting. If you want more meaty experiments,
look at the newer digital modes: clover, PacTOR, etc..... Ok, what
about designing HF rigs themselves? There are all kinds of new things
that can be done with filtering, for example (DSP being the new world to
play with).
Ok, granted, some (much) of this is out of the budget range of your
average person, but there are other areas that I've left out in my quest
to have this system shutdown while the thunderstorm is still a couple of
miles away. Oops...time's up.
