Subject: Reluctant regen regens!
Message-ID: <Pine.SUN.3.95.970121210241.24518A-100000@spike>

Moved the throttle condenser to the correct side of the RF choke, then
clipped a 190 pf variable cap across the 100 pf throttle.  Using the
80 meter coil with a few windings removed on the tickler (41% of tank
windings), the receiver began regenning by playing with the two
throttles.  Broadcast breakthru eliminated by playing with trimmer
variable cap and the throttle(s). Full 190 + 100 pf is needed for the
low end of 80 meters with less capacitance needed while moving up
towards 6.5 Mhz (about the upper end with these windings). 

So, I'm happy now.  Will experiment with windings for other bands and
with different ways of narrowing the band coverage closer to the ham
bands.

Thanks, guys!  You're great.

   There's some of us who actually *enjoy* CW, who want to continue using
   it.  I also personally believe in the discipline associated with
   learning the code.

Yes, and yes, agreed. (I lost my mike many years ago.)

   My argument is....don't take away or whittle on the existing CW
   bands, they're already crowded and the digital modes are really taking
   up a lot of room. 

The argument *should* be: let's put the most amount of life into
the CW bands, so that we can maximize the likelihood of this mode
being available for the enjoyment of future generations, who may
also come to love it as we do. 

It's disgusting to tune across 80 meters late at night, hear
nothing, and tune up in the ssb (75 meter) band and hear quite a
decent amount of activity.  WHERE ARE THE CW OPS? 

It's disgusting to tune across 80 meters in the daylight hours,
and hear nothing but static -- and then when W1AW takes to the
air: there it is: a 599+ signal!  WHERE ARE THE CW OPS? The only
thing that wipes out the static is a living breathing operator
(OK -- so W1AW uses a robot...).

How do we make the cw bands come alive?  By giving the novices and
technicans their own segment of EVERY cw band.

1900-2000 Novice and Tech +
1950-2000 Technician 

3600-3750 Novice and Tech +
3700-3750 Technician

7100-7150 Novice and Tech +
7140-7150 Technician

10130-10140 Novice and Tech +
10140-10150 Technician

14100-14150 Novice and Tech +
14125-14150 Technician

18100-18110 Novice and Tech + and Technician

21100-21200 Novice and Tech +
21180-21200 Technician

24920-24930 Novice and Tech + and Technician

28100-28300 Novice and Tech +
28250-28300 Technician

6 meters and up: unchanged

Our BASIC THINKING on this issue has to change: it's *not*
generals vs extras, or novices vs. generals or everyone
vs. technicians but   *ALL OF US*   vs the static.

I am dismayed at the poor use we hams make of our alloted cw
spectrum space.

   If they want to give the Technicians HF priviledges
   that's fine...just keep 'em out of the CW bands...they won't be
   CW-certified anyhow, right? 

What really is a ham cw band anyway?  MOSTLY UNUSED SPECTRUM
SPACE, i.e. static (contests excepted) !!  Let us all look that
*FACT* squarely in the face. If you think I'm off the mark, just
tune around and listen for yourself.

 CW is dying partly because we are *discouraging* rather than
*encouraging* the cw neophytes in our midst.  We are turning them
off by our "good-old-boy" mind set; which is nothing more than a
form of hazing: "I had to go thru it, so you sure as hell are
going to have to go thru it!" 

By *forcing* people to "learn cw" in order to participate in the
HF spectrum, we are turning people away from CW -- sort of like
mom forcing us to eat our oatmeal -- after we leave mom's table,
do we ever again eat our oatmeal?  We should not *ever* force any
ham to learn cw because it is a "requirement".  Hams should
*want* to learn cw by seeing the fun we have with it.

   And don't carve a chunk out of the CW
   bands for a place for them or for anyone else,....leave the CW bands
   alone!

You mean leave them to the static?  And in any case, just because
some other mode is *also* allowed use of the spectrum doesn't
mean that we have "carved a chunk out of the CW bands" -- it just
means there is a little more competition for the CW ops -- and
isn't it competition and difficult condx that helps make CW our
mode-of-choice?

Why don't you find any CW "inside" the phone bands?  Do I have to
give an answer?  It's because there is already too much spectrum
for too few CW ops.

TOO MUCH SPECTRUM FOR TOO FEW CW OPS: this is what we have to
look squarely in the face, and think up creative ways of
reversing this trend.

Maybe I missed something - is Glowbugs a forum for this sort of 
discussion?  I was under the impression that most of the GB'ers
ARE cw operators, and that there are Newsgroups for the CW topic.

I really don't relish the thought of an endless debate with
lengthy copied messages being dumped in my in-box, a debate I
chose not to participate in ages ago and just shut up and fired
up my CW rig instead.

Or am I not correct?  Does anyone know what the group concept
for this is?  

Thanks

How did you arrive at these frequencies? I suggest you subscribe
to the TopBand email list (devoted to 160m) and make this suggestion,
then check into a burn ward, for you'll be flamed to a crisp!!
Make sure you get to know a band well before handing out segments
such as this!

Now, please take any and all discussions about code/nocode to
rec.radio.amateur.policy, a newsgroup created exactly for this
debate. I'll be very glad to introduce you the gang on there;
we've been arguing this topic for years over there. But *please*
keep this issue *off* of GlowBugs!!!!!!

Message-ID:  <[email-masked]>

Hi Gang,
Took a small detour before I start my 6L6 transmitter (almost have all
the parts for it and the supply) and built Bob Shelton'd 50C5 one tube,
two band kit from the Spring 1996 Homebrew. I can certainly recommend it
to anyone who wants a "tube experieince". I breadboarded (?) it and
other than winding the coils in opposite directions, it fired right up.
With a builtin voltage doubler, it is ready to go.  All parts minus the
board. I have assemebled some other QRP rigs but must confess that when
the 'orange glow' starts, it's a "total" experience.
Bob includes a 3700 crystal - not a 243 but one of the aluminium cased
ones. I would like to get something in the 40m band - say 7040 and below

7060. I know that the 243 are in demand but are the aluminium one easier
to get?   Where can you get them and what do I ask for?
Thanks for all your support.  The kit is great.

Back in 1985 when the James River had it worst flood in better than 75 years
my Dad's store took a hit of 7 ft of water.  This is in VA to those of you
that don't know. There was about 50 years of things that he and Grand Dad
and myself had saved.  In my area were the Majestics, the RBM, the Zenith's,
20+ years of QST's and many parts. I had two days to help him clean the
store out and a pickup truck for a day to take stuff to a dump. I had to
hustle. Do you know how much 20 years of WET QST's weigh? The cabinets  of
the Majestic's just came apart--what a mess.  We loaded everything we could
on the pickup truck and drove to the sink hole on the farm we were using for
a dump--I'll always remember giving the Majestic chassis's a heave with a
sigh.  I shudda pulled the tubes,  I shudda pulled the tubes. I do know
where they are buried.  We had to work fast in fact my father-in-law who
came to help us will never forget my Mothers comment to me. "Jimmy, slow
down-it's a flood, not a fire". I shudda pulled the tubes. 73 Jim K4CGY

Can't help you with the pie-wound chokes in the old style (I am assumming
you mean the bobbin style characteristic of the 20's yes/no?).

I would almost give me eye teeth (If I still had 'em) for a good
coil winder that WOULD wind a bobbin pie decently.  There has gotta
be a good way to do this other than the hand/motor drill chuck method.

Maybe this would be a topic for some threading in the list.

My usual method is to hand wind or motor wind on a bobbin (often a
real thread spool cuz that works pretty well) of some sort.  It is
crude, but for 250 turns or so, it works on the usual 160/80/40 sort
of glowebugge thingie.....

> 2. Bell Wire.  This is old red/white or blue/white cotton covered wire.
>                I could ues 50 feet.

The last old cotton striped bell wire that I saw was from a telephone
system that was being dug up (lead covered 100 pair stuff or something
like that).  The older brother and a neighbor got about 10 pieces about
5 or 6 feet long and cut the lead off to melt and recycle.  The kid
radio geek would a WHOLE BUNCH of xtal radio coils on that stuff for
a long time.  Alas, that was back in 1955.

If cotton covered wire is not critical for periodicity, I like the
standard hardware store bell wire in 66 foot packs for a buck or two.
It also makes a good length for the cheapskates simple simeon quarter
wave ether launcher for 80M, in a pinch, and is handy for an odd
receiving antenna.  The yellow or green colors look pretty good
wound on old regen coil forms.  I have seen 500 ft spools around
the hamfests here in the East for 3-5 bucks a spool, occasionally.
I will buy several rolls at that price if it pops up.  It is always
handy for wiring GB projects.

If anyone knows of a source of the real cotton striped stuff in
reasonable lengths (maybe 50 or 100 feet, sufficient to wind the
usual regenerator coils and the like), do holler back to the list.
It might be fun to find some period wire for such coils to give
the coils a polished finesse.

Good Luck finding the real McCoy.....

Well, the band was fair, and I did manage to work ten or so stations,
of which several were list folk!  Yeah!

Brian/AF4K in MD was there as well as Sandy/W5TVW out in LA.

The QRN was rough last night, for some reason.  Maybe the warming wx
down south blew the last weekend's quiet peace.  Last weekend, the
top band was armchar copy on the regenerator.  I was getting 2.5
amps rf out, but I dunno its QRD.

Mebbee I needst checkie-checkie my antenna for ether leaks.....
Big Bertha seemed weaker than normal on the other end, although
the regenerator was pulling them in outta the mud.

It was a fellow in PA running a genuine 5 watt 6Y6 final vfo QRP rig on 160!
I was surprised to even hear him at all.  Kudos to a top band tube qrp
GB fellow, even though I don't think he is on the list.  Mebbee we
should invite him.....

It's appropriate for glowbugs only in that we (as homebrewers, of whatever
technology) represent in most cases the last thoroughly nutso advocates of
CW.  If CW withers away, we lose a priceless heritage.

By encouraging the creation of CW rigs, we can help keep CW alive.  Tubes or
sand, whatever it takes, I say.  I do both.

My suggestion has always been this: Work within the clubs, and make CW an
*adventure.*  Do it on the buddy system.  Get a class together, and make
teams out of pairs of people who are physically close to one another.  Then
get them to make their own simple CW rigs and try to contact one another.
If the team is less than a mile apart, this is a slam dunk.  In denser
areas, people can be a few blocks apart, and make Q5 contacts on 75mW out of
a single transistor.  Give the guys some reason to claim bragging rights: "I
built this crummy thing out of almost nothing and somebody heard it a mile
away!"

THAT'S how to keep CW alive.  If I ever hear the "I hadda do it an you do
too" argument again I'm gonna start throwing things.

But realistically, an involved discussion on this list isn't appropriate.
Let's just keep the technology alive; without the technology the spirit of
CW will follow into history.

Subject: Coil winders--build your own?
Message-ID: <[email-masked]>

Hi guys--

Bob was pining for a coil winder (like those wonderful ones I used to drool
over in the 1961 Allied Radio catalogs Uncle Louie gave me) and I wanted to
remind interested parties that Lindsay Books publishes a booklet on building
your own coil winder.  The book is by Dave Gingery, who has written a number
of other intriguing books for Lindsay on building a lathe out of junk car
parts, building an electric furnace out of dryer heating elements, and great
stunts like that.

I don't have a Lindsay catalog here at work but they're somewhere in central
Illinois.  (Bradley?)

I'm hoping to build one at some point, tho I'm more likely to use parts from
my Meccano set.  With care, you can create separate pi windings with #36
wire , looping back and forth to minimize interwinding capacitance.  The
trick is keeping the wire in place; I think you may have to spray some sort
of stickum on the pi periodically to keep it together.

The only mechanically tricky part of such a mechanism is the cam that moves
the wire "snout" back and forth.  Again, having an old Meccano or Erector
set (which can be had at garage sales) would make that lots easier.

If I ever go ahead with the project (time has been almost nonexistent
lately) I'll post reports here.

Well I don't know of a direct source, but I do know that cotton covered
wire is still being made.  In my business (telecommunications) AT&T now
known as Lucent Tech. supplies cotton braided wire.  When me and a buddy
whos a Ham were working on some new Lucent equipment once we noticed the
stuff and couldn't believe our eyes.  Here we stood in front of some
High Tech. fiber optics equipment and they were using cotton braided
wire!
Quickly with a pair of dikes and some disecting we found that the braid
is woven over a filler (possibly PVC, etc) and then comes the copper
wire.  This is new (1996 vintage) equipment that the wire came with so
it's not old wire.  

Now my story ends on the note that someone (possibly Lucent themselves)
is making the stuff. I've seen some of the stuff at local hamfests where
telecom installers are scavenging it from the dump and selling it, so I
see two possible sources, new and used.  Unfortunatly, I suspect to buy
it new would require at least a 1000' minimum or more.  Used - well I've
seen it a couple of times at Hamfests disguised as wiring harnesses so
it's available this way.

I don't know if this rambling helps anyone or not, but I've got a few
feet of the stuff and it's great for replicating the "old" wiring look
safely.

BTW the cotton cover was re-created (according to my supervisor) because
of the Hinsdale, IL central office fire.  The PVC catches on fire to
quickly, and the cotton has been treated to resist heat....

I was looking for the early digests of the GlowBugs mailing list in the
sunsite archives and it only starts at issue no. 032.  By any sort of
long shot in the ether bucket, does anyone have email copies of the
early glowbug digests 001 through 031 still about, or have they gone

This is a great suggestion.  I talked with a Novice buddy of mine like 
this when I first got licensed until I felt ready to tackle "the rest 
of the world", and the thrill was indescribeable -- probably more so 
because we were talking in an exotic (!) "code".  I think the biggest 
barriers for the rank beginner are (a) passing the 5wpm and getting 
licensed, and (b) getting a @%$* crystal in a Novice/Tech band.  I 
wonder if low-power self-excited operation at the top of the BC band is 
feasible over a mile or so, both using the strict FCC guidelines and a 
slightly more liberal "don't bother anybody" approach?  (I'm sure the 
FCC is just waiting to pounce on any 200 mW stations using 25' 
antennas, right?)

Subject: Waddaya do wid ole tv junker tubes --- regenerate of course
Message-ID: <[email-masked]>

Whilst pondering the deepest mysteries of regenerators wats glows in the
manner befitting any self-respecting Glowebuggeite, I thought a list of
generic triode tubes in the leftover tvscrappo piles that would be suited
to the making of a cheapskate's regenerator (wat else we can do with them
thar unused tvscrappo tubes, eh?), might be of benefit in the reference
department...... thus.....

1  Many tube types have several filament voltage ratings from 2 to
   as high as 117 volts, although the usual ones are 2, 3, 4, 5, 6,
   8, 10, 11, 13, 15, 17, 18, and 21 volts.  Among these types you
   will often find a 2, 3, 4, 5, 6, and 12 volt equivalent.  These
   are usually from TV series string filament applications, and often
   wind up forever unused in the junk box.  But, they can often be
   pressed into service in regenerator circuits, with a little bit
   of thought into what filament voltages you may want to run, and
   how you may want to obtain them (one source parallel, or maybe
   a series string of 2 or 3 volters on 6 volts, or 4 or 6 volters
   on 12 volts ac or dc operation).

2  The 7BT basing is a dual diode plus triode design, that can be
   used as a straight triode in regenerator service, quite well.

*********************************************************************

Other triode types may exist, but that is all I could find in a quick
perusal of the tube manuals.

Enjoy.... and Happy Glowebuggeing.

I must be a real cheapskate, because I would never buy by the foot
for wire if it were possible to buy at least a 100 foot roll.  The
cost would eat up all of my little bit o' Glowebuggeing guildern
de realme, in a hurry.  The only exception would be square bus bar
wire.  That I would probably not use sufficient quantities to buy
in the roll, although if I ever would run across a big spool of that
stuff, right.....(:+}}.....

Remember that the average regenerator coil for 160M can eat up gobs of
wire, for one coil, or well over 75 feet, easily.  A whole set of
coils for 160/80/40 could eat up a couple of hundred feet, if you made
no misteaks(....) and got the coils right on the first time (rare in
my book).  Add 10 or so feet for general wiring of a receiver and even
a plain regen can eat up the wire, if you don't look after it.

If you are winding a choke coil with 250 turns on a 3 inch form, go
figure...... (maybe 250 feet very roughly).  

So, buy by the foot if you have to, but try to pick up at least a first
order discount for a 100 foot lot.

If you see the stuff under the tables at hamfests, in the odd wire
boxes around those big trucks that show up just dumping the surplus
out the back, maybe we should stoop and snoop a little and see if 
a big shareable roll of that fine ol' cotton stuff is about.  If
you can't use it particularly, maybe another of us can.  I often
buy the bell wire in about no 22 guage any time it surfaces at
the 3-5 buck a 500 foot spool.  So, maybe we should all look around
at the next years hamfests and see what can be garnered therefrom.

Anyway, if anyone has that AES catalog handy, what are the pricings for
that cotton covered wire, in sufficient quantity for a regenerator?
That would be 100 foot or 500 foot lots.

Anyone know if the Newark or other biggie distributors carry it?

Can anyone find out where the fone company was getting theirs?

If anyone can find a 2,500 or 5,000 or 10,000 foot spool, would a bulk
order for the group be feasible?

Just thinking out loud..... what is that pennywise vs footpound foolish
or sum such like that.....(:+{{.....

Thanks

Subject: Tubes For Glowbugging..........
Message-ID: <[email-masked]>

Gang:

Received a flyer from Antique Electronic Supply last week, and I
see that they have some obscure tubes on sale that are of possible
glowbug interest.

One is the 6DB5 beam power tube. A 6W6 with a 9-pin miniature
base. Plate dissipation 10 watts. Same as a 50C5/50L6GT and the like,
but with somewhat higher ratings (max plate voltage 300). Cost
is 50 cents each. Filament 6.3V 1.2 A.

If you don't mind odd filament voltages they have 10GK6's
(same ratings as a 6BQ5 but different pinout) for $1 each and
the octal 26E6WG (ratings about the same as a 6F6 or 6V6) for $1.50.

My order went in today....don't worry, lots left for you guys
as well. 

No, I don't own stock in AES........they do appear on my credit card 
bill on occasion however.
