I also ponder this from time to time.  It seems as if the guys who
do the repeater coordination would HAVE to be the ones who are most
involved in USING the repeaters - chances are a guy who never uses
a repeater won't want to take the time to be involved in their
coordination.  This isn't necessarily a bad thing, as long as the
repeater councils stay within the agreed bandplan (which covers
ALL modes, and hopefully comes from an organization which respects
the needs of stuff like experimental and weak-signal work).

Everyone (including the federal government) now recongizes the radio
spectrum as a limited resource.  Unfortunately, it isn't respected
as such.  The general philosophy is something like: "They are
running out of frequencies so we better reserve a couple now in
case we want them later".  It is very difficult for a repeater
frequency to be re-issued, unless the original owner has died,
because within days someone will complain "it's just being fixed!"

This is the reason I am against having packet channels coordinated
by the repeater councils - I don't think any coordination should
operate in this mode.

One problem is that there is no practical way to say, "There are enough
two meter repeaters in this area - try 900 or 1200".  As a 'self-
regulated' radio service, we aren't doing a very good job in this
respect.  Amateur radio is by no means isolated, either - two examples
close to home are a 450 commercial repeater on campus, so that the
stage crew can talk in a one-mile radius around campus, and an
STL frequency given to our campus broadcast station so they can
link the studio to the transmitter -- 1/4 mile away.

All this discussion of closed vs open repeaters and CTCSS (which seems 
such an attractive solution) brings up the question:

If two stations transmit at the same time on the input of a repeater,
one with the CTCSS which the repeater uses and one without, what comes out
of the repeater transmitter?

If the CTCSS signal is stronger, he comes through. Otherwise, nothing. Right?

Yes, Ed, you are quite correct, because the CTCSS decoding takes place at
baseband audio AFTER demodulation. The really sad part is that this is not
fully understood/appreciated in the Land-Mobile arena, where it's assumed to
be the panacea for their congestion problems. We have that precise situation
here in northern New England where a fire department in the Boston area has
a very powerful repeater outputting on a simplex frequency widely used in
central New Hampshire to dispatch about 35 departments in the region. Although
CTCSS is in use, the handhelds in NH are continually being stepped on by
the Boston area repeater (which only has to serve about 10 square miles; why
they have to be dead full quieting in valleys 70 air miles away is unknown).
Oh, BTW, the department near Boston is eligible and is using many other
frequencies on other bands, making their VHF high-band repeater requirement
a bit dubious anyway. In any case, the FM capture effect continues to work.

I have an R-388/URR reciever.  It is a very nice unit.  As far as I
know, the 388 is exactly the same as the 51J-3, except for the name
plate.  For receivers of its age, it is a fine unit (mine was made
in 1954).  One thing that you won't like the absence of true
product dectector for LSB / USB reception -- all you have is a BFO.
I think the 51J-4 has a product detector(?...). I don't know if
there is matching military version.

Here are a couple of hints:  be sure the VFO tracks correctly.
It seems that the corrector stack can go bad Check the tuning
against the internal calibrator.

Make sure the tuning slug racks move freely.

Don't use a solid state rectifier replacement for the 5V4 without
use of appropriate ballast resistor.  The design accounts for
voltage drop in the 5V4; problems arise if the plate voltage is too
high.  Mine had a solid state replacement in it when I bought it;
it worked much better when I installed a real 5V4 for the
rectifier.

Be sure to get the operators manual TM 11-854 / TO 16-35R-388-5.

The December 1992 (boat show) edition of the French yeachting magazine
"Bateaux" has a picture and writeup on an interesting new Sony radio.
It is the ICF 55. Like their older all-wave models, it covers from 150 kHz
to 29.999 MHz, and the FM band from 76 to 108 MHz. There seem to be two
interesting new features:
	> It is "really" intended for SSB reception.
	> It tunes in 1 kHz steps (not 5 kHz like the older ones).
	> It has a real and substantial rotary knob for continuous tuning.
	> Less importantly, it's dial seems to be a very large gee-whiz
	  LCD affair with world map, lots of numbers, etc., etc.
I have no idea how large it is, but it's clearly not a "baby" unit.

The French price is 3200 F, which is just under $600. I would expect the
USA price to be a lot less, maybe about $395 - since things are just
cheaper here.

No endorsement given.

Questions that require perfectly spelled answers (such as calls)

Multiple choice allow for a marginal error in copying callsigns 
and such (they are sent only ONCE).
Fill-in-the-blanks test comprehension and minimize passing with pure luck.

A FM receiver typically responds to the strongest signal ... known, in some
circles, as the capture effect.

    Desense is when a strong out-of-band signal causes the AGC of
the receiver to cut the gain, which affects the in-band signals.
As a discone antenna will pick up a very broad band of signals
whereas the whips don't do so well, this could very well be your
problem.
    Adding a trap to filter out the offending signal will help,
particularly if there's only 1 strong local signal.  If there's
more than one, you'd need several traps.  Try a series-resonant
LC circuit to ground at the offending signal's frequency.
Depending on the Q of the circuit, you could get >30db of
attenuation there without affecting anything else.  Install this
trap where the coax comes in to the scanner.

BZZZZZZT! Wrong answer!  Have you checked your ARRL band plan lately?  The
sections of 3/4m below 440 are set aside for modes like TV, and weak signal
work, and EME, OSCAR, and CW, ...  If you want to see some hams really get
honked off, try running FM in the weak signal, SSB or CW areas!

The area from 440-442 is setaside for ATV, 442-445 are for FM repeaters, 
and from 445-447 are control links and repeaters, and 447-450 are repeaters,
leaving 446.0 as the sole and only FM simplex frequency allowed for in the
ARRL band plan for 3/4 meters!

I know that some areas deviate from the plan, but this ARRL plan is the ARRL
plan that I mentioned in my earlier posting.

Secondly, ICOM 4ATs only cover 10MHz of the band.  It's all I have.  I would
gladly upgrade if your would give me your commercial version of the 04AT, or
maybe your Porche ;-)

I hope I am not prolonging the "closed repeater" thread but I
would like to put a couple of comments in before it (I hope) dies.

We have a repeater here in New Jersey (call, frequency and location
omitted by design) that I think typifies the problem. This
repeater is owned by a club. The repeater comes on the air,
generally, between 6 and 11 PM. The repeater is used **ONLY**
for DX spotting, so if there is nothing rare on the HF bands
then the repeater is quite **EXCEPT** for the IDing that lets
you know there is a repeater there. 

The repeater is operated as a closed repeater and the PL 
changes monthly or quicker. To be a member of the club you 
**MUST** have a DXCC number. The last I heard there were nine 
active members in the club.

I feel that if at all possible the repeater coordinator(s) should
reassign the pair in cases like this. Maybe the FCC should delegate
the power to do this??

I do not disagree with closed repeaters, (I don't like them) but
to use the "if your going to play you must pay" analogy then,
unless the owner of the repeater is independently wealthy, you
should be willing to pay for the maintenance, etc to use the 
repeater.

[Begin forwarded message]
You can post this from me with the note that I will have more info
when the team members return - I will answer direct questions as 
well but the response will be a little slow as I have other work
and I shall have to track down some info - I am software person afterall.

The decision to use an optic fiber was made early on because of the
amount of information being sent (ethernet, several video camera, and
several serial i/o lines - I shall get a full list later - all on a
single mode fiber using a special in house designed board). The
original set up had Dante's fiber part of the power cable, however
this failed early on due to a bad cable - the fiber didn't work under
cable load! Getting a new tether with power and fiber would have taken
too long - this project was only for this year. To solve this we made
use of another fiber which was going to relay information from a
second autnomous robot which was built named Virgil who was going to
transport Dante to the rim. Virgil fell out of the picture for other
mainly tranportation reasons and was replaced with a simple wheeled
cart named Geryon.

This "yellow" fiber was then hand wrapped and passively paid out by Dante.

The radio was not used was due to a combination of factors, primarily
driving us was time, the amount of information, the amount of
available power on the Dante, the fact that we were not line
of sight and the desire to only put computers on Dante that we were
used to programming (again the time factor) and could withstand -40C.

The video for nasa select was with a compression board in one sun
tcp/ip via satellite TDRSS and decompression on the other end. This
required encoding and decoding a clock which we built a board for but
the goddard folk provided us with a clock off of the satellite links.
I will grab more detailed info on that as well.
