Looking for copies of the manuals for the Digital DECwriter II and

(There's plenty of room in the cage to put a small TNC...)

The procedure is the same whether you are a US citizen or a foreign
national.  The exams are the same also.
However, there are two things which must be considered:

1. A foreign national must not be an agent of a foreign government.
Basically this means that you must not have diplomatic immunity
to prosecution if you break the law.

2. You must have a mailing address within the US or Territories.
(presumably anywhere there is a US Zipcode), and similarly
a station address within the US (these might be the same address
if you don't use a Post Office Box or Rural Route).

If you are a student this shouldn't be much of a problem since
you should be able to receive mail from the school while you are
attending.

The N connector was named by a guy with the last name of Neil.  The C
connector by a Mr. Concelman.  (Not sure of spelling.)  

The collaborated on the BNC connector:  Bayonet-mount Neil-Concelman.

The TNC is a Thread-mount Neil-Concelman.

I think the "SM" in "SMA" stands for Sub-Miniature.  There is also an
"SMB" and "SMC" connector, so I think the "A" is just to serialize
the series.

UHF means Ultra-High-Frequency.  When these connectors were invented
back in the 40's (30's?), anything above about 30 MHz was considered
"Ultra-High".

The main reasons I use N connectors instead of UHF are that
the N type is water proof (unlike the UHF) and the N type
doesn't require soldering to the braid like the UHF type.
With polyfoam coax, this is very difficult to do without
a lot of heat damage.  Think about it:  no other connector
besides UHF requires soldering the braid; they all use 
crimp or clamp type attachment.  Even (chuckle) RCA connectors
now come in crimp versions so you don't have to solder the
braid.  The only crimp type UHF connectors I have seen are
for RG-58 only, not RG-8.  And these are not waterproof like
clamp on type N's.

Extra cost??  K-Mart's sporting goods department sells a beautiful
Delco "Voyager" sealed maintenance-free Group 27 (105 AH) battery for
just $69.95.  I have one sitting under this desk, and in conjunction
with a Tripplite SB1000b SPS, it reliably runs my two Unix setups for
more than two hours.  The battery doesn't slobber all over itself; it's
as neat as a Gel-Cell.  This same battery is available at Price Club,
Costco, etc. for roughly $50. Deep discharge batteries aren't really
more expensive. 

An ordinary car battery, for whatever chemical reasons, will not stand
significant discharges.  Two or three really deep discharges, and it's
a total loss.  

If you want a very nice "inside" battery, get this Delco "Voyager";
it's the nicest such battery I've ever used.  I now have it in several
SPS systems at my radio station.

I built a Knight T-60 (1962), which miraculously worked the first

power supply in the T-60 nicely modulated the VFO I was powering
from it, so I connected scads of pulled electrolytics in parallel 
to try to smooth out the ripple.

The VFO drifted a mite, too, so I left the power on all the time.
One day I encountered a basement full of noxious smoke. A small
flame was visible inside the transmitter, and the meter was
melted! Yes, an electrolytic had shorted.... A fairly large
quantity of tar had poured out the bottom of the transformer.
I carefully scraped it off the chassis, heated it in a tin cup,
and poured it back in! I replaced the relative-power meter with
a 150-mA meter for plate current (so I could dip the plate 
current on 80 meters, and not accidentally tune the final to 
the second harmonic--I had more states confirmed via OO 
notices than QSL cards), and got back on the air. I later sold
the T-60 and built a 6AG7-6AG7-807 40/20-meter transmitter,
but that's another story.

That 610 would have a forged signature on it.  Odds are that it isn't even
close to looking like a real signature of Joe Ham.  Convincing the FCC
may be a bit difficult, though.  Fingerprints on the bogus 610 might
finger the tricksters (assuming investigators have time to spend on

Posted to: telecom@eecs.nwu.edu, rec.radio.amateur.misc

I'm developing a product for stutterers that will process 
speech when talking on the telephone.  To connect the 
processor to the phone, I bought a "phone patch" for ham 
radios, the MFJ Telepatch II, for $69.95.  It works fine, 
but if I get this working well I'd like to sell them.  I'd 
like to find a cheaper phone patch, without the ham radio 
features I don't need.

Are there other manufacturers of phone patches? I have the 
schematic for the MFJ unit, but if other phone patch 
schematics are available, I'd appreciate a reference.

All I need is audio in and audio out.  My processor unit 
will have volume controls for both.  I suppose I should have 
something to keep the outgoing level below -20dBm, as I 
understand that the phone company doesn't want levels over 
this.

I don't think I need the microphone or speaker jacks, null 
adjustment, etc., that the MFJ unit includes.  I don't need 
the circuits to switch between sending and receiving voice, 
as telephones do both at the same time.

Lastly, if I sell more than 20-30 of these, I'll have a 
complete circuitboard designed with a phone patch on it.  If 
it connects to the handset jack, not the phone line, can I 
avoid FCC Part 68 certification?  I understand that 
certification costs about $20,000.  Will the phone patch 
circuit be substantially different?

Hello Net Folks!

Does anyone have a source of SAW (Surface Acoustical Wave) filters
commonly used for removing the larger portion of an AM video signal?

Such filters are made by Plessey and CTI, but I haven't been able to find a
source for these filters short of cannibalizing an existing video modulator
that uses a SAW filter to produce vestigial sideband AM.

I need a VSB SAW filter for VHF-TV channel 3 (video carrier = 61.250 MHz)
for an Amateur Television (ATV) transmitter I am currently in the process
of designing and building (who said all hams are appliance ops?), but have
found it extremely difficult to find an outlet for SAW filters.

BTW, I wrote to Plessey and haven't received a response in about a month.

If anyone knows of a source of SAW filters suitable for VSB filtering of
a VHF-TV channel 3 video signal, I'd sure appreciate hearing from you.

Please e-mail your responses, and I'll post the replies.

THANKS!

nachos died a terrible death several months ago (disk crash) and since it
was a very ancient Apollo DN3500 we decided not to expend resources bringing
it back up.  We are otherwise disk limited and I could not scroung available
space on another machine to maintain the archive.  However--

Cliff Yamato at JPL is now running an FTP site that mirrors the same element
sets that I was carrying on nachos.  The details are:

	hostname:	kilroy.jpl.nasa.gov [128.149.1.165]
	directory:	pub/space/elements/nasa
				pub/space/elements/molczan


I get elements emailed from Dr. Kelso and then (usually :-) ) forward them
to an automatic process on kilroy which puts them into the FTP directory.

Ted Molczan's elements are mailed directly to Cliff by Mike McCants.

We normally see new data on a weekly basis.

BNC - Bayonet Niell-Concelman         "
N   - Niell			      "
C   - Concelman                       "
HN  - High Voltage Niell
UHF - Ultra High Frequency (when 30MHz was UHF).

SSMA - SubSub Miniature type A
MHV - Medium High Voltage (variation on BNC)
