The ARRL email server has a file devoted to this band. Send an email
to: [e-mail] and only write:
index
quit
and you'll receive a very long list of available files. Look for the
1750M file and order it according to the instruction.

  Best guess based on what little you've told me.

  You have a windsheild antenna. It has a break in it. As the windshied
  warms up, the break is bridged and the signal magically appears. The
  cost to repear this is either a simple reseating of the connection
  point at the base (usually) of the windshield or could go as far as
  having to replace the entire windshield assembly.

  But it definately sounds like a temperature (i.e. expand/contract)
  related problem.

  Please let me know what you find out. I like to know when I guess correctly!

Let's get a few things straight !   Entering the ham license info into
the computer at Gettysburg may only require 8 staff hours a week (probably
not a man).  BUT......
     1) Who buys the paper / pays the postage / etc. ?   Who DONATED their
    new computer ?  Is there a supervisor ?
     2) Do the FCC/Washington people like W3BE and secretary and maybe
    an assistant DONATE their time?  I thought they were paid.  Someone
    has to handle the rulemaking petitions and other harassment from
    the hams at large.  Or maybe you want this activity delegated to
    the ARRL...who would doubtless do it for free (NOT!) ;-)
     3) Do the government people who go to the international allocations
    meetings and fend off a certain number of threats to the bands DONATE
    their time?
     4) Etc.
Thinking that amateur radio costs the taxpayer no more than the salary of
one nice lady who types in the license info one day a week is like thinking
that the only cost in a broadcasting station is the on-air people.  You DO
work for free, don't you Gary ?

Hmm.  If how much we pay an agency determines how responsive they are,
we each should have our very own little IRS agent as our personal slaves....

Whoa, Batman.  This presumes the FCC has some sort of title to the radio
spectrum to dole out to the highest bidder.  Funny, I can't find any
constitutional authority for that.  In the FCC's charter to regulate
the spectrum, it could make a case that the greatest good is for the
amateur frequencies to be used elsewhere but they certainly can't make
a case for selling the frequencies.  That they now do so is a
testament to apathetic the population has become.

Boy, you dropped it on this one.

No. But you know by now that I would always encourage someone to build
rather than buy. ``Keep the soldering iron hot and the fingers cool.''

I see lots of construction articles in the magazines and books; my '91 Hand-
book has a chapter devoted to `UHF and Microwave Equipment', and I believe
the ARRL has entire books devoted to these subjects. Possibly critical
componenets can be gotten from the surplus market. I read that construction
techniques are quite different `up there' than what we're used to on the
lower bands (i.e. 2M). I've heard that it helps to know voo-doo...


>Are propagation characteristics on those bands such that they are as suitable
>for FM voice communication as is 440?

Good question. I'm curious as to what 420-450 characteristics are lost at
the higher frequencies. Why wouldn't they be suitable replacements for
VHF? I imagine there's more shadows in high building density areas; less
refraction, more reflection. Radio waves start behaving more like light.
I'm hoping someone will point out the critical differences.

I guess this is pretty obvious is you already *know* how to
build radios out of TVs.  But, if you don't have this background,
I'm not sure how true this really is.  I suspect a lot of
amateurs can no longer tell you what the specialty ICs are
used in various consumer electronics really do, much less rewire
them up in amateur applications.

On the other hand, surplus microwave stuff is often more straightforward
to deal with.  You can often figure out what frequency the stuff operates
with a ruler (if it isn't marked on the case).  Much of the circuitry is
still discretes, or at least nice understandable building blocks, often
with 50 ohm input and output connections.  Thus, some modifications
consisist of merely tearing out all the junk you don't need, and hooking
up what you do need.

True, getting 10 watt transistors is still a challenge on most of the
microwave bands.  But, low power microwave parts are relatively easy
to get and getting easier, as companies realize they have to actually
sell stuff to stay in business.
