I was able to find suggested replacements for several of the tubes asked

from a GE domestic tube guide.  The domestic replacements may not be

A few of these tubes are still manufactured in the US by the employee owned
company that bought out GE's plant in Lexington, KY, when GE closed the plant.
They make mainly small industrial varieties including a few transmitting
tubes like the 807, 6146, and 7984.  They also make a few of the more popular
domestic varieties.  Most small vacuum tubes are now made in eastern Europe.
I guess the replacement market and the audio "phreaks" are a big enough 
market to keep these companies going.

I've had similarly excellent results with the Avanti antenna.  
I currently have three.  One of  mine has been installed since I
bought my El Camino new in 79.  I've done fairly extensive
testing of the 2 meter antenna vs a Larson  5/8 wave mag-mount. 
Under most conditions the Avanti performed as well as the
Larson.  The differences seemed to be as much a function  of the
differences in radiation angle as anything. 

The key to eliminating the problem you mentioned is to not use the 
sticky tape.  I believe the current antennas and the remount kits use
silicone RTV to mount the matchbox.  In any event, I've used RTV
since the sticky tape came loose on my first Avanti in about 1980.

The only really critical thing is to accurately tune the matchbox.
The antenna does act like a dummy load if the tuning is even a little
bit off.  Beg, borrow, or steal a Bird or equiv wattmeter and do it 
right.

A few years ago I was stunned to hear music comming from my Model 15
Teletype!  I was in contact with a friend in RTTY when the bell on
the teleprinter rang out 'Jingle Bells' (just before XMAS). It was 
in one tone but it was quite unmistakeable.  (somehow I don't think
it would be the same on an IBM pc)

Keywords: Yeasu, FT-1000, CT, Computer-control
Date: 21 Jul 92 21:39:45 GMT
NNTP-Posting-Host: bbn.com

Hi all,

I thought you would be interested that I received a letter from Yeasu
last night acknowledging the fact that the initial FT-1000 computer control
software was not sufficient for high-speed contest operation with CT.  For
those of you unfamiliar with the inner workings of the FT-1000, the problem
is that for CT to sample the frequency or mode of the transceiver, it has
to do a "Status request" command that returns about 1400 bytes of information
at 4800 baud.  That takes about 3 seconds, which is a significant amount
of time for a serious contester (which, by the way, I'm not).

The interesting bit is that because of the number of comments on this by
FT-1000 owners, they will now offer an upgraded ROM for the transceiver that
will enhance the computer control link software to permit selective
requests (at least, I assume that's how they solved the problem; they didn't
say in the letter).  They will provide the ROM *free* to those owners wishing
to install the upgrade themselves, or, at your option, will do it at the
factory (presumably at some cost).  The factory upgrades will be *not*
be done immediately, but will be scheduled at a later date.  I assume
all new FT-1000s after this point will probably have the new ROMs.

So if you are an FT-1000 owner and CT user, you might look for a letter
from Yeasu Musen USA in your mailbox.  I have to admit to being very
pleasantly surprised with Yeasu's commitment to their (admittedly high-end)
customers and their willingness to back that up with their own dollars
(namely the free ROMs).   I thought I'd just pass the word on to others
who have not gotten their letters yet.

This varies from state to state. In Texas:
EMTs are not required by law to stop and help. There is some case law that
suggests that someone who is identifiable as an EMT (by a car sticker, for
example) who does not stop at a scene may be held liable for problems caused
by the delay between the time he passes up the scene and the time EMS
personnel arrive, but this is a bit sketchy.
The Good Samaritan law protects anyone who acts in good faith at a scene; if
that person has medical/EMS training, he will be held to the same standard of
care as if he had a duty to act, but he's protected as long as he adheres to
that standard.

FWIW, I strongly support helmet laws; there's a 100% correlation in my
experience between survival of serious motorcycle accidents and helmet use,
and I've cleaned up too many dead motorcyclists off the road.

Well I don't know why this is happening, but for some reason the
last few sets of TS Kelso numbers haven't agreed with the amsat
numbers.  One set puts AO-13 in one place and the other somewhere
not even close.  I first noticed this on Field Day.  AO-13 didn't
show up!  Going back to three month old numbers saved us.  I FTPed
from the site TS Kelso's postings points to and got the same bad
numbers for AO-13.

Using TS Kelso numbers about three weeks ago I found that AO-13
shouldn't be visible, but it was.  Using the amsat numbers placed
AO-13 somewhere completely different, but visible.  I can't tell
you that the position was right on, but at least it was right about
AO-13 being visible.  And it was AO-13, I copied the RTTY beacon to
verify that I was hearing AO-13 not AO-10.

Now I use the amsat postings.  I save the Kelso numbers too, but I
don't use them unless the agree with the amsat numbers for AO-13.
The strangest thing is that sometimes they do and other postings
don't.  I alway make two runs and keep the Kelso numbers only if
they agree with the amsat numbers.  What is going on?  Is NASA
confusing AO-13 with another bird or something?

Thanks for the comments on the IC-2SRA, Glen.

Does anyone have any thoughts on how the wideband receive capabilities
of the IC-W2A compare to that if the 2SRA?  The 2SRA has the wideband
receive and scanning features that I like, but the W2A is a dual-band
radio, which I also want.

The 2SRA seems to have wideband coverage as a documented feature,
whereas on the W2A, as far as I can tell it is a "keypad" mod to get
the extended coverage.

Are there any other handhelds by any manufacturer that I should
consider too?

Thanks,

Hello all,

The amateur radio club here at NASA-Lewis Research Center is in the 
process of creating new QSL cards. Our old one is a black-and-white 
picture but we want a new one using color pictures that will give
whoever who receives it an idea of what NASA-Lewis does. 

Therefore I would like to get information about the QSL card
manufacturer that your company or local ham club uses. A few things 
I would to mention:
1) We would be ordering 1000 or more cards for our first order. 
2) We need someone who does custom work and accepts color pictures
since the QSL card will either be one full color picture or a 
collage of 3 pictures.

Any info, name, prices, your personal views, reliability, etc
about the company is also welcome.

Thanks in advance.

If you break down 70 miles into the desert, there's no cellular service,
no passing vehicles for the last two days that you can flag down, and
the buzzards have started to circle, you still shouldn't call a commercial
towing service. You should call the Sheriff's Rescue Unit. It's not an
emergency unless you need emergency services personnel.
