To: [e-mail]

    Looking for information (elect drawing) for 6 German radios
    from the 1940 period.  All have tubes, and work.  Nice wood
    cab.
        Remember if it does'nt glow, it not a radio.

Dave:  I do a lot of hiking in the sierras and never had problems hitting hams
(some as far as Las Vegas).  I use a Yaesu FT11 with an AEA 1/2 wave antenna
(I think is called the Hot Rod) and with only 1.5 watts!.  The trick is to be
at a high elevation with no trees around you.  I also notice that near granite
walls (plenty in the Sierras) your TX and RX are even better (I think granite
is a very good reflector(?) of RF and acts as a giant dish antenna).

I have also contacted people on simplex as far as Fresno (CA) from Kings
Canyon NP  (about 80 miles away!).  Again you have to be in the right spot.
Near Yosemite you can hit the 147.000 repeater which is linked with 147.030
down in the San Joaquin Valley.

Happy hiking and hamming!

Rafael, KE6JSR

Good idea here, but in connecticut we routinely make 50-70 mile qso's via
6 meter FM with mobile and base rigs at about 50 watts.  A good qth is
a big factor, but if you have relatively open terrain, 6M will give you
very reliable contacts.  These mid-distance (VHF-wise) contacts seem to
be uneffected by propagation fluxuations (E-skip and tropo) except for the
racket on 52.525 when the band opens!!

Look for converted Motorola's for low $$$ and get a pair on the
same freq, such as 52.525, and you should be in business.

I am thinking of getting the new GAP 80-10 vertical. On paper it looks
great and the price is much better than the R7. I would like to hear
from any and all users of the GAP antennas and see what everyone thinks
of them. I would hate to make a real big mistake by getting this and
finding out that everyone but the reviewers hate the antenna.

FOR BEST LIFE, NICADS NEED TO DISCHARGE DOWN TO 1 VOLT PER CELL. THE BETTER
CHARGING METHODS ARE 1/10 OF THE CAPACITY FOR 15 HOURS OR THERE ARE SPECIAL
NICAD CHIPS WHICH USE SIMPLE COMPONENTS WHICH CHARGE TILL THE CELLS REACH
THEIR PEAK VOLTAGE AND THEN DIP SLIGHTLY. THERE WAS AN ARTICAL ON THESE IN ONE
OF THE RECENT HAM RADIO MAGAZINES.

Well I used to top mine off everytime I used them and after a year
or so they had very little left in them. So I discharged them down
to almost zero and then charged them up again and what do you know -
they were back to almost normal capacity. So you've got to discharge tehm
deeply, at least occassionally. I don't know if you should do it often
or not, but that's my story.

Be carful how far you bring them down, you may go past the point of being able
to bring them back. One volt for each nicad cell is a good rule of thumb to
determin when to start recharging them.

There's a place in Alexandria (or Arlington) Virginia (very close to DC) that

The Ham Radio Outlet is located in Woodbine VA.  It has a lot of equipment
and decent prices.  However, you will need an automobile to drive down
there.
Just take 95S and take the Woodbine exit, it is about a 1 mile from the
exit.

There is also Maryland Radio Center in Laurel MD which is really closer to
D.C. than Woodbine VA.  They have competitive prices on ICOM and Kenwood.
However,they don't carry a lot of the items in stock but order them. They
have a fair amount of equipment available but not nearly as much as HRO.
They
do have antennas, mounts, etc.

Look around for a ten tec argo 509, it should be about $300 and is
a standout QRP rig.  5 band, cw and ssb, hears well and has a great
on-air sound.  5w on cw and 2w pep on ssb, you may not be busting
pileups but hey, whatta rig!

The nice thing with the argo is that outside of a mini backpack
single-band qrp cw rig, it may be the last qrp rig you ever need.

for single band rigs look at oak hills research, and especially KANGA-US.
The catalog alone is enough to get one on qrp!

73 and good luck

Thank you for reading this.

I'm looking for information from anyone who uses the Crushcraft R7 vertical
antenna.

Any information you can remember about it will be helpful;good or bad. I'm
looking to get one and would like to hear from actual users of this antenna.
Any problems you have had setting it up, adjustments, SWR problems, hardware,
anything you can think of will be helpful.

To: [e-mail]

        SETIQuest is a new quarterly print/electronic mail (E-mail)
    periodical containing news, technical information, and tutorials
    devoted to bioastronomy and its subset, SETI (Search for
    Extraterrestrial Intelligence).

        SETIQuest is published for professionals, serious amateur
    astronomers, and individuals curious about this fascinating field of
    observation.  SETIQuest fills the need for a specialized astronomical
    publication devoted exclusively to the on-going search for evidence
    of life in the Universe.  Such evidence could be intentional or
    inadvertent signals of other civilizations.  Such evidence could be
    found in spectral signatures of biological activity on extrasolar
    planets or in the interstellar medium.

        SETIQuest is written and edited for the scientifically literate
    individual taking part in the progress of our technological
    civilization, with articles by amateur and professional scientists.
    SETIQuest includes information about hands-on observational programs
    that can be carried out by individuals and groups of amateur
    astronomers at radio and optical wavelengths.

        SETIQuest is filled with articles covering topics such as:

        * Tutorials about bioastronomy and SETI
        * Microwave or optical SETI as practiced by amateurs
        * "Do-it-yourself" participation in bioastronomy and SETI activities
        * Book reviews
        * Regular commentary on issues relevant to SETI and bioastronomy:

        SETI and the political milieu

        Philosophical issues regarding the prospects of success and
    failure in the search

        SETI as a parable of science versus pseudo science

A friend of mine has an Icom 551D 6m multimode with the FM, IF shift
and VOX modules, 80 watts output.  AES lists a price of about $500,
but he's wondering what he can really get for it.  I've seen (and worked)
the radio, it's in IMMACULATE condition.

So what's it worth?  He hasn't decided if he'll sell yet, but a good offer
might tip the scales.
