Paul Prescott writes about allowing the I.F. to oscillate as a means for
creating a BFO.

That technique was used to a great extent for a period of years.  If I recall
correctly, the Halicrafters S-38 and other inexpensive receivers of that era
used this technique.  Although I can't recall the name (Super Q or some such
name) at the moment, several articles were written around the oscillating I.F.
to enhance the I.F. Q factor for selectivity and some sensitivity improvement.
With so many ways of skinning the cat, one has to make a choice as to which

Recently, Scott NF3I was lamenting about not being able to put
up antennas for 80 and 40 due to covenants on his property...

Fear not!  How about putting a HF antenna on your car and running
coax into your townhouse window?  

I've had very good success using the Hustler mobile HF antenna
setup on 40m CW running only 5 watts with my Ten-Tec Argonaut.
I worked Maine to Massachusetts and got about a 559, for example.
The Hustler antenna setup consists of a five-foot aluminum "mast"
(radiator) to which you add a "resonator" for your band of choice.
(Incidentally, the vertical alone is about 1/4 wave on 6m.)
Yes, you will have do some significant drilling to mount this to
your car, or you could build one of those monster mag-mount things
that was in QST(?) recently.  The 40m resonator has a very narrow
bandwidth, so you'll have to adjust the top whip section if you
move around the band much. This sounds like it would work very
well for your situation, too.  Total cost (swivel mount base, mast,
and resonator) would probably be around $50 to $75.

Of course, you could build a fine "fixed mobile" antenna from scratch:
1/2 inch copper pipe for the vertical section, wind your own coil on a
short piece of PVC, and add some welding rod for the tip section. Mount
it on a piece of plywood that will set on the roof of your car. For the
ground side, run some braid to a large alligator clip to the car body
(rain gutter?). You'd have a temporary antenna that the covenant cops
probably have no grounds to complain about. Total cost of this setup
would probably be about $10.

Finally, a end-fed half-wave worked fine for me running 75m SSB with
my Argonaut to make contacts throughout New England. Of course, living
all around wetlands helped! :-) RF in the shack was a big problem when
I put my Icom 735 running 100 watts into it, though. A good ground
helped that. Maybe a really thin wire end-fed half-wave on 40m, about
65 to 70 feet, would work for you especially if you ran low-power for
less potential TVI/RFI and CW to get the most bang for the low power.

73 and good luck...

You might try the Century Club net (7.233.5 or 3903.5 Mhz) or the
Geritol net (I've forgotten the frequency but it's in the extra
class portion of the 75 meter band).  They often have West Virginia
and Delaware and it should be a easy to get them from Connecticut
(much easier than it was for me in California).

If you're interested in a little less power, the 4CX250B makes a good
400 watt amp (down 1 s-unit from legal limit).  The hamfests in this
area are lousy with used 4CX250Bs - most of them OK.  At <$10/copy, the
price is right.

These tubes are used by chip manufacturers to etch silicon with plasma.
Rather than risk botching an entire run of expensive chips, the tube is
swapped out early with plenty of life left.

The tube itself is very well behaved.  Even a hacker like me can design
a workable linear amplifier from it.

Identical experience I had at Ft. Dix 05B school, except in operating procedure
class, we learned to verify operators from a code book to make sure our nets
weren't infiltrated by charlie.  (victor charlie that is).  I had been a novice
as a kid when it self-destructed in 12 months, and never was too proficient at
copying cw.  Under the military method my cw shot up to about 25 wpm in a few
short weeks.  They sent me on to  05C school (RTTY) then 31M (multiplexed FM
UHF stuff).  I was inactive after that for literally 20 years (1969-1989) and
found I could copy cw 5 wpm cold (no brushing up) and in a month I passed
the general cw test. The training really sticks!

The other things that I remember fondly was the gear, hand crank generators,
Prick 25's, kite elevated longwires etc.  and the operating procedures.  If
you said "Over and Out" you were immediately humiliated with the "Sky King
Award", as the two were exclusive procedures.

An individual who trained as a radio operator during WW II said that
they were forbidden to pick up the pencil until 45 seconds of code had
been sent.  They were forced to "copy behind", writing down what had
been sent 30-45 seconds prior.  This technique has been recommended
by various sources over the years as essential for high-speed code
operation.

Service manuals for most Tandy/Radio Shack products are available at
a nominal (usually) charge from Tandy National Parts, if your local store
either doesn't know how to order them, or doesn't seem to want to do it
for you.  What you want has a part number of "SMxx-xxxx".  For example,
the service manual for a 25-1000 would be P/N SM25-1000.

Their 800# is 800/442-2425, and they take plastic money, ship UPS next
day, if you want it (you pay the freight, obviously)

Yes, most popular personnal computer is NEC's PC-9800 series. (usually named

(I  have one)
There is (or have been) many type of '98. And NEC releases some new model in every 
six months. (for magazine's article ??)
 All of them is DOS machine. (But remember, ver# is different from PC-DOS)
DOS used in  usuall is called MS-DOS 3.3D (what is 'D'??) or some use DOS 5.0A.

Character of typical (hi-end) '98 is ( like PC9801FA)
CPU: 486sx 16MHz RAM: 1.6MB Display: 640*400 dot 16color
Price: about $2,200- (not list, at discount store) for basic model (without HD)
(of cause, without display, machine and keyboard only)

Which do you like to buy when you have $2,200-, PC98 with 486sx+640*400, or 
PC compatible with  486dx+SVGA ??

of a good antenna design I can build or, perhaps, a signal amplifier or
even an antenna kit that might do the job? This is a powerful Portland

Er, I know this is not what you asked, but Radio Shack has a book with

once you know the characters start increasing the speed once you are copying
65-75% of the characters. That way you are allways pushing yourself and

OK, Bob Smits VE7EMD finally stirred me to response on this thread!! 

First, Bob, you're a brother ham and I respect your point of view....for no
reason other than it's yours and you're entitled to it. However, I disagree.

First, DXers aren't necessarily a "subculture" of Ham Radio....way,way back
"DXing" ....that is, trying to make as many contacts as possible over the
greatest distance possible....was the main way that improvements were 
developed and demonstrated. The competitive aspect of it all goes to the
very roots of Amateur Radio, and if it were not for such appeal to the
competitive nature of those pioneers, I daresay the technology might not
have progressed so rapidly. You can measure that in terms of prestige, or
satisfaction or money profits, but it's all based in competition.

So (IMHO) it might be just as fair to say that the rest of Ham Radio is
really a spin-off of DXing, rather than the way you put it, Bob.

Again IMHO.....Ham Radio as a whole seems to be considered by most to be
a "hobby".....but most DXers I know look on their activities as a SPORT...
and like most sports, there are your more laid-back, weekend practitioners
(like your neighbor, the golf duffer who just enjoys 18 holes on Sat morning
for the exercise) and you have your pros, like Arnie Palmer who eat, drink,
and breathe golf....in between, there are many levels of capability, interest,
expertise, dedication, investment, and competition. All the weekend golfers
I know look up to those pros, watch the competition eagerly as fans, and
learn the finer points from them. Of course, some of the pros on the
circuit are real jerks and the rest of the pros will be the first to say so.
It's that way among DXers, too.....the good ones deplore the kind of
behavior and tactics that started this thread in the first place.

So, Bob....my friend....please don't toss the baby out with the proverbial
bathwater.....condemn the behavior. 

Sorry for hogging the soapbox for so long..... 73, Jerry K1MER
