I've been lurking here for a few months now...saw the thread on
regenerative receivers and thought I'd put in a question or two.

I had started building a battery-powered receiver a while back...the design
was a cross between two projects I found in a book.  It used a 1S4 detector
and 3S4 audio amplifier.  I think I got a few wires crossed someplace that
shouldn't have been, though, because (1) it never worked right and (2) when
I returned to it a couple of months later to try to fix it, one of the D
cells used to drive the filaments was dead (I think there was some filament
power hooked up someplace even when the thing was supposedly "off"). 
Between lack of time and what would be the relatively high operating cost
(two D cells for the A supply and three 9-volt batteries for B+), it ended
up becoming shelfware.

In three grab bags of parts I picked up at the last Las Vegas swap ($10 for
three one-gallon Zip-Locs of assorted parts), I picked up a small handful
of different types of tubes.  One tube in particular, a 14F7 dual triode,
looks particularly neat--and it looks like it might be of use in an
AC-powered regenerative design.  The specs aren't that different from the
12AX7, which was mentioned as a good candidate for this type of job. 
Developing a power supply shouldn't be too hard, either--A can be a simple
12V transformer (should have one or more of those around here; if not, even
Radio Shack carries them) and B can be a diode (either a SS diode or the
12AF3 that also was in one of the grab bags) and a nice big electrolytic
capacitor to get 120-160V B+ (depending on the type of diode used).

Does this sound doable, or am I smoking something?  B+ is a bit higher than
the 36V or so that has been bandied about here, but the 14F7 is good for up
to 250V B+ and this simple diode-capacitor power supply would be a hell of
a lot cheaper than a transformer for some mid-range voltage.  The two
loctals I have (a 14A7 was also in the grab bags) are neat-looking tubes
and it'd be nice if I could put at least one of them to work in something.

One of the projects on my (growing!) to do list is the
Low Power Phone/CW Rig for 1.8 MHz (sorry, Mc) as described 
in the 1969 ARRL Handbook. It uses two 6T9 triode/pentodes, one
as the oscillator/RF output (xtal controlled) and the second
as the modulator. A 12AT7 is used as a speech amp. About 15 watts
out on 160 metres, see no reason it would not be good on 80 or 40
as well with the proper coils. This is a AM rig...a SSB rig would
be more complex. 

6T9's are $2.30 atr Antique Electronic Supply.

Hi radio fans!
It was a busy Monday night on 3579.5! The band is in excellent condition
with trans-contenental DX between
NA4G in North Carolina runnig a Heath HW16 and N7TM in Washington state
running a Drake 2C/2NT combo.
Also worked were several stations dropping by for the first time. Stations
on were:

KC5TJG/Geo in Wichita Falls, Texas
W5FRS/Dennis in Texas running a great sounding TCS (look ma, no chirp!)
W5TVW/Sandy in New Orleans running a SR150 into a Henry amp (WWL's second
cousin!)
N2CQR/Bill in Va running a Halli HT37/Drake 2B
VA3RP/Rod in Ontario running a Heath DX60B
NA4G/Bob in NC with a Heath HW16
N7TM/Tom in WA running a Drake 2C/2NT combo
K4MSG/Paul in Va running (classified)
AF4K/Bry in MD running (classified) 
WS4S/Conard in TN running HB 6V6->6Y6/R-390A
Also heard calling but not worked was K7FJ.
 
How about some of you BA/GB ops in exotic DX-lands (KH6/KL7 etc.) make some
schedules with us 
for a late-night session so we can work you with our flea-power rock crushers?

If you want to get in some great CW time with an excellent group of
operators, here is your chance.
Come up on 3579.5 after dark with whatever you can find that radiates a
signal. Wait until someone
turns it over to another op and send your call. With the onset of decent
propagation on 80, even 
5 or 10 watts will do fine.

I don't often get up on the stump with a tirade and epistle from The Old

but my email handler (standard unix sendmail with elm) is having trouble
with mime/metamail mailings from the list.  Emails should be 100% plain
flat ascii only to properly conform to unix standards.  Of late certain
email handlers think they own the world and want to get too fancy.
If you have one of these emailers, kindly turn off any mime or metamail
encoding switches, so the Boatanchors of the unix world will stay happy.
I am trying to find the mime/metamail extensions and build them into my
mailer but that will take some spare time (scarce these days).  Until
I build them into my boatanchor unix box, mime/metamail > /dev/null.

HEY! It's a reply from AF4K!

Say Bob - several of us here are going tobe working on an ECL82 
transmitter (Is it 6GW8 or 6BM8?) - anyway, you could start out with 
the basic CW transmitter and then add your SSB generator later.
The tube is just right for a 10 W p.e.p. final, and it contains a 
triode and a pentode. Plans for the basic CW TX should be available 
in a few days.

Robert--

I have an AM project in the cooker in the form of the "essential" handbook
modulator: The one (I'm using a 1964 handbook) that uses a pair of 6BQ6
sweep tubes at audio, working through a UTC S-19 modulation transformer.
It'll plate modulate up to 50W of RF.

I'm going to try using a steel chassis (from AES) for the experience, since
I've never used steel before.  I have a full set of chassis punches so the
only struggle will be making a hole for the S-19's jungle of solder tabs.

I haven't gone after it because there isn't much AM out here, but I have all
the parts and could begin any time.  Once I finish my priority project (a
simple 4-tube superhet) I'll probably start in on the modulator.

But my first fone contact back in 1975 was screen modulation on my Knight
T-60 Novice rig the Friday night after I got my General in the mail.  My
club (Northwest Amateur Radio Club in the Chicago suburbs) had a net that
night, and whereas I was the only AM signal there they were gracious about
it--however, the pressure was on HARD to get on SSB.  I bought a ratty old
Central Electronics 10B but I never quite got a linear together with enough
oomph to make a difference, and finally caved in as soon as I could and
bought a Kenwood TS-520.

I do AM now and then when I hear strong signals, using my Icom (eek!) but
the glowbug crowd can hear the constricted audio and always asks, What kinda
ricebox you got there, Jeff?  Brute power helps on AM but I really don't
want to screw with power supplies well over 1000V.

I'll post my experiences with the modulator here but it's going to be a
couple months yet.

Good luck and don't give up!

Just got delivery of my order of transmitting micas from All Electronics.
Fast service, by the way!  Those guys are aces at getting orders out fast.

The parts are all visually intact, undamaged and usable, but all are removed
from equipment and some are a little dirty.  Don't see anything clean enough
to be NOS.  The manufacturers are mostly Sangamo (love their logo!) with the
rest either Elmenco or unbranded.

I won't be able to test them until tonight but I'll report if I find any bad
ones.  If you don't hear from me it means the lot tested out fine.

I, for one, am well pleased with the turnout we had and the general band
conditions lately on the BA/GB QRG.  I was beginning to think that it
was becoming a lost cause.  But, with the crew that showed up last nite
it was GREAT!  Lets follow the pattern for the rest of the week and the
weekend and see how it goes.  I was amazed to hear N7TM and K7FG so well
on my puny HW-16.  (Never use a HW-16 in the presence of strong locals,
cuz it blocks worse than a toy regennie --- I have some 599999999 chops
down on 3520 within a couple of hundred yards in two directions, and
when they come on [fine ol' navy an' cg chops that can blow yer socks
off an melt yer bug contacts if yer not careful], the HW-16 goes deep
six from the overload.)  Even the ol' RAL regenerator heard them  7's
on a tiny indoor antenna, too.  Mebbee tonight I will fire up Big Bertha
Radiomarine and let her belch a note or two.  Conard's fine lil' peanut
whistle came through 599 from TN to NC.  I almost turned on the ol' lady
Grandma Hartley, last nite, but the shack was in too much of a mess to
handle the switchover safely without standing on the ol' headbone.
Sandy's lusty barnburner held the fort well, from LA.  FB on the west
coasters who joined in.  Let the west coast be heard!  

The bands are hot, the bottles they be a' glowin' brightly, an' the
regeneration be on the ragged edge!  Grapples ye up yer tin cans atops
yer noggins, an readys ye yer keys at the fore!

p.s. Anyone got a good circuit design for a 5 section LC tank tunable
     passband filter that I might could use to knock down the overload?
     I got this 'ere ancient 5 section variable somewhares that might
     make fer a good tunable front end on the HW-16.  If I could build
     it strong enough to pass the 40 or so watts of RF then I could just
     drop it in the line.  If not, then I hafta break out the QSK output
     to the rx section and pass it through the tuner that way......hmmm....

Jeff,

Your story reminded me of why I became a virtually CW-only operator.  When I
was a novice (also in 1974-75 at the age of 14-15) I had a Globe Scout 680
CW/AM rig much like your T-60, and the day my General ticket came I was itching
to try phone.  I plugged in my mike, and tried to tune the rig but got
absolutely
nothing.  I put the switch back to CW, and loaded just fine.  Then to AM but
still
nothing.  This went on for a day or two, but I finally gave up after not being
able to figure out why the AM section was dead (my troubleshooting skills were
not yet very developed!).  So I went back to CW and had a ball in the general
section of the band working in the 'wide open spaces' with my newly acquired 
Hallicrafters HA-5 VFO (still have it).

Only later did I find out that most of the AM rigs of that era required that the
KEY BE REMOVED FROM THE KEY JACK before using AM to complete the cathode circuit
and produce a carrier!

By the time my parents teamed up with Santa to bring me a shiny used SB-101
SSB rig,
I was an OT on CW and didn't have a burning interest in phone anymore.
Nowadays,
I run a TS-820 in addition to my DX-60, DX-40, Drake 2C rcvr, S-120, and a newly
built 6L6 transmitter (gleaned from this group - Tanks!), but never bother to
use SSB.

At least now, when I fire up the DX40 and plug in a mike to say howdy in the
local
75m AM net, I remember to unplug the key!


Just my little anecdote!

Yes, Robert, I am also fond of AM fone and am fairly active on the HF bands 
using the mode. I use a plethora of gear, all homebrew by yours truly, or 
highly modified commercial rigs. One of my creations is a legal-limit PDM/PWM 
AM transmitter, but that's not strictly a glowbug topic (marries those high-
tech sillycon thingies with an 833A as the pulse width modulator toobe and a 
pair of 4-125A's in the RF deck). Another is a 6EW6 -> 6AG7 -> 6DQ6 rig which 
runs 35-40W output in CW for glowbuggin' or 8-10W screen-modulated AM. I like 
AM operation because (1) it sounds good, (2) it is practical to build 
transmitters and receivers that work well, and (3) the round-table operating 
style allows me to be in QSO while I'm working on projects at the bench.

Incidentally, I agree with Bry/AF4K that Dave/WB7AWK need not worry two much 
about consuming too much bandwidth, as long as the signal is free of 
overmodulation, distortion, and the resulting splatter. One advantage of using 
that audio amp as a modulator is that he can use the bass and treble controls 
to tailor his frequency response to conditions - when the band is crowded, 
attenuate both lows and highs 'cause the guy at the receiving end won't be able 
to take advantage of the wide range audio anyway. When the band isn't busy, go 
for high fidelity and there's no harm done. My approach is to design the 
transmitter for a flat response throughout the full audio range, and use 
equallization to adjust for conditions.

They have a toll-free FAX number:

For all voice traffic call

Have NO idea who that 800 number is--it's not AES.

Boy, do you guys know how to bring back old memories! I got my novice
(WN4IUY) in 1974 at age 14. I was running a Hallicrafters SX-42 rx and a
homebrew 50w input TX built from an old handbook project. I ran rockbound
until I got my general ticket. Once upgraded, I bought an Eico 720/modulator
and a Johnson VFO-122 at the local hamfest. Boy, was I ever big-time then!
40 meters phone was fun, but the SSB guys were realy giving me a lot of
flack about my AM signal. I quietly began to slip back down to the CW
segments...suddenly I realized how nice the general CW segment were, and
hardly worked any more phone for several years.

Over the next few years I was "glo-buggin" A lot. I built several TX's: 807,
6DQ6, 2-6146 (!), and a 6T9 (I think that's right). I also built a few
simple rx's from various handbooks. My commercial complement grew to a
Valiant, Viking II, SX-101, HT-19, heath apache/mohawk combo, and a
super-pro. There were a few more in there somewhere, but I don't remember
them as well. 

Anyway, so much for old memories. How many of you remember the nights when
you'd turn the lights in your room off and watch the almost magical glow of
the tubes in the dark??

Being that it was just last night, the memory is quite fond!


But seriously, I know exactly what you mean.  I have almost always operated in
a near-dark room, with only the panel lights to log by.  I now have a track
light
on a dimmer and lower it to that level, and still prefer to operate that way.

Also, I just finished a 6L6 xmtr that uses an OD3 regulator tube.  I
intentionally
put a view-port on the front of the rig to allow the mystical purple light out.
I now want to make up a little circuit to use a 6E5 (I think that's it)
'magic eye'
as its tuning indicator, in addition to the panel meter.  I have 1 of these
tubes
that's NOS from my teen years that never got used.

Thanks, Roy for straightening out my dyslexia!  I mated the 800 part 
with the local part, and inadvertently send some calls the way of
the RV place. Boy, I hope no one asked them for a good deal on a 6T9!

There's a little-known Fifties-era magic eye called the 6AL7, which is a
*twin* magic eye unit, where each "eye" is a rectangle of light that grows
to about 1/4" X 1/2" or shrinks down to a line.  I don't know what it was
ever used for, but I found one in a junkbox I bought years ago and I've been
itching to find something to do with it.  Believe it or not, there's a whole
article (by the estimable Don Stoner) on the 6AL7 and how it's used, and
I'll certainly entertain notions of a good use for *two* magic eyes in a
single project. Any thoughts?

Like a lot of "weird" tubes, the 6AL7GT is fairly cheap ($3.50; cost of a
so-so hamburger) at AES.  It's smaller than the 6E5 and uses a standard
octal base.

What area are you in Gordon? And where does that local AM net meet?

Is the DX-40 plate modulated or screen?
The T-60 was a good little rig, but its 30W of AM didn't carry too 
far when condx got rough!
I mostly ran it on 40m AM when I wasn't on CW.

Not at all Tom! We will be patient and go slow with you if you like.
There are enough straight key operators in this bunch to keep you
