I've looked to see if such a thing (fm voice) exists within D-Star.
Could these folks steer us to some documentation? Here are the RF
modules I've found:

The FM voice is not part of the D-Star specs. It is built into the
ICOM hardware. The IC-2820 dual-band dual-channel mobile comes
"D-Star ready" for $600 and the add-on D-Star module is another $200+.

I'd just as soon wait for the prices to come down.

Do you know of any coordination or frequency placement issues involved
with opening a presumptive FM side?


No, the local coordinator handles that as any other frequency
coordination matter.

You know that whole D-Star "repeater" is not a repeater issue, so
frequencies are opened up for it in repeater crowded areas. Those
frequencies would not be proper repeater frequencies for an FM repeater.

Do you know a reference for that action Phil? I've looked a bit on the
FCC site, but haven't found it yet. I think it was in 2006.


According to what I've heard, that's a "hot button" topic, but Bill
Cross of the FCC (an active ham) said at Dayton that he applies the
"duck test" to the D-Star repeaters (making them eligible for
automatic control).

That makes good sense to me.

As I understand it, some D-Star advocates are claiming that a D-Star
repeater isn't a repeater, because the regs state that a repeater
retransmits the incoming signal "instantaneously", and the packet
delay in a D-Star system makes it not-instantaneous... that it's
fundamentally a store-and-forward system, more like a BBS (albeit with
a very short storage time).

That same line of thought (if valid) would seem to apply to a fairly
high percentage of ham-radio analog repeaters on the air today. It's
quite common to have a digital or bucket-brigate delay device in the
receiver audio path, with the analog audio being presented to the
repeater controller and transmitter some time (up to tens of
milliseconds) after it was actually demodulated by the receiver. This
can help reduce the chopping-off of the first part of the first
syllable, and allows the transmitter to be un-keyed at the end of the
transmission before the beginning of the squelch-tail noise burst gets
out of the delay pipeline.

I can't recall hearing anyone argue that an FM analog repeater with an
analog bucket-brigade (or even ADPCM digital) audio delay circuit was
magically "not a repeater" because the audio retransmission was not
"instantaneous". If the D-Star not-a-repeater proponents were to win
their case, it might be a *very* pyrrhic victory, as analog repeater
owners might also qualify to move into non-repeater frequency
segments. Sauce for the goose...

Right. My thoughts on the whole thing are that with the Bizarre
"repeater that isn't a repeater" argument they couldn't run FM analog
because it would turn the "repeater that isn't a repeater into a
repeater that is a repeater."

Now repeat that ten times real fast! ;^)

Our repeater system uses several polling receivers at different sites.
(6 or 7 IIRC) The recievers transmit their received signals to the main
site. The main repeater site determines which is the strongest signal,
and sends that one through to the main repeater transmitter.

As you can imagine, there is some delay there too. Maybe 250 milliseconds.

One of the biggest problems putting up a repeater these days is that
many areas are just full. There's no room at the Inn. And the area in
which a D-Star is likely to do best is in those crowded areas. So they
tried to do an end run around the issue. Without a lot of thought.

Seems like we have a nice patch of bandwidth between 2 meters and 440
that is a bit underutilized?

Depends on the definition of "full" or the definition of "crowded".

I live in a metropolitan area in which there are no VHF pairs available for
assignment. By some definition that might mean that the spectrum is "full" or
"crowded".

But you could shoot off a cannon on 2M most of the time and it wouldn't hit a
soul. Nobody. Not a signal to be heard. Some days you can scan every channel
in sequence for hours on end with not a peep heard. Then go to each QRG in
sequence and transmit "K0HB LISTENING". Nobody home.

I travel a lot, to large cities like Chicago, Milwaukee, St. Louis, Tucson,
Kansas City, Indianapolis, Detroit, OKC, DFW, Tucson, Phoenix, Denver, El
Paso/Las Cruces. It's the same everywhere. Just a scattering of signals on the

The NFCC needs to quit being the lapdog of the repeater owners, and do some

Well, "listening" generally is taken by an increasing number of folks as
meaning you are listening, not that you are soliciting a call. If I hear it,
and I also have some reason to talk to you, I may call. Of course, if I had
something to call you about, the cellphone in my pocket probably already took

If you want to talk to someone, call them, or call cq.

True. 10 - 15 years ago, they were busy. Now --- silent. It seems that way
everywhere.

I know that for me, I now have a small car with no good place for a rig, and
park in places where one might not want to leave one in the car. At home, being

I don't know what took the interest away for everyone else. However, with

It is possible that I live in an anomalous area, but in Central PA, the
repeaters are pretty busy. And State College is the smallest
metropolitan area in the country. We have 5 repeaters, although one is
down for maintenance right now. Altoona to the southwest has a number of
repeaters that have traffic on them also.

naive mode on:

One of the most interesting aspects of Amateur radio is that we kind of
expect someone to be waiting there to talk to us. While we can't control
what happens in other areas, we can control our own.

If we want to generate traffic on the repeaters, the simplest way is to
generate some traffic on them. Get a friend and talk on the thing. Next
thing you know, others will join you. If enough places do that, there
will be plenty of traffic.

naive mode off:

That is what we did in our area. Traffic was down, and the obligatory
bemoaning of the problem was up.

We just had people get on the air and yak it up. Could be coincidence,
but more and more people joined the party, and a few years later the
repeater is in constant use.

This is one that Hams themselves have to bootstrap.


The NFCC needs to quit being the lapdog of the repeater owners, and do some

Interesting concept, but how to determine use or lack of use? (sounds
easy, but in practice it isn't.

It's certainly that way in rural Minnesota. There are repeaters in many
of the small towns, and they're alive in the sense of being technically
there, but they're dead in the sense of anyone using them on a regular
basis. Sometimes there's a regular group who gets together in the
morning, but for our local repeater even that custom has faded away.

We lost our UHF repeater almost a year ago when the elevator it was on
was destroyed by lightning. [For you city slickers, the word "elevator"
out here in the sticks is used to describe a large structure in which
grain is stored.] That repeater is still silent. A new location was
secured, and funding for it was provided by the local emergency
management agency, but the antenna still hasn't been erected.

So I have to wonder, in metro areas where all the slots are "full", how
many of those repeaters actually exist and would respond if presented
with a correctly-toned signal on their published input frequency.
Perhaps more important, how many of them are used regularly? It might
actually make more sense to shut down several repeaters that don't have
a critical mass of users and move those small groups to the remaining
repeaters so that there was actually someone there to talk to. Better
to have two or three active repeaters in a metro area than a dozen dead
ones.

It's a chicken and egg problem. I know that I'm contributing to the

that I need to buy a "real" 2-meter rig and put up an antenna . . . but
it's difficult for me to justify the time and expense to do so when
there's no activity.

When I hear someone say "listening", I think, "that's nice, they're
listening". I'm listening, too. If I don't know them or have some reason
to talk to them, I don't call them.

The NFCC needs to quit being the lapdog of the repeater owners, and do some
spectrum management housecleaning.


So now it is also the responsibility of the repeater owner to protect
his investment in equipment by seeking people to use his repeater all
the time? Otherwise, it will be "housecleaned" out from under him?

Do we have enough people to use all the possible repeaters all the
time? If not, then "housecleaning" to open spectrum up for other people
to install repeaters will just result in more empty repeaters. If you say
you just want to houseclean out all the unused repeaters and replace them
with nothing, what value is the housecleaning? You'll remove valuable
resources and replace them with nothing. The only "gain" (in the former
case) will be that new people who want the status of owning a repeater
will own repeaters that are empty. No gain at all in the latter.

I'll point out the opposite opinion: a repeater that is filled with
chit-chat all the time is unlistenable. It just drones on and on and
becomes background noise. Couple that with people who think they need
to be cute and entertaining on the air and it's no longer just noise,
it's painful. We have a "lunch bunch" on a local system every day. The
net control seems to think a sing-song delivery and "creative phonetics"
for everyone checking in is mandatory. I know some people like it. I
find it difficult to understand what he's saying most of the time. Is
he saying something important, or is he just spouting words with the
right first letters for the callsign he just heard? I turn it off.

I didn't make my point very well. We don't need to "generate traffic", we
simply need to clean out the dead "legacy" assignments and free up room for
things like DStar and other emerging technologies.

I just had a look at our local (Minneapolis/St Paul) pair assignments. In the
2M and 75CM bands there are 108 repeater pairs assigned. You read right --- ONE
HUNDRED AND EIGHT! Yet I can scan both bands for hours on end and hear nothing.

Since this thread is about the "5th Pillar" of ARRL emphasis, "technology",
perhaps ARRK and NFCC could jointly sponsor a Skimmer-like technology initiative
which would put up a broadband receiver on a local highrise (we're in flatland
country out here) and count squelch-tails per QRG for three months. Then
approach the low 10% and suggest they might reconsider their needs. Especially
those clubs who sponsor multiple quiet repeaters all covering an identical
footprint.

If you know a "dead" frequency pair, what interference do you imagine you

you from using that pair?

which would put up a broadband receiver on a local highrise (we're in flatland

I'm not sure how you count "squelch tails", but that's such a simple

"active", I'd simply make a dozen calls a day on the output frequency. (Is
THAT what this QRG thing you keep talking about is? I don't speak CW

If there are a dozen repeaters with zero activity, most will go dead in
any disaster because it takes real human interest and work to provide
emergency power. I'd rather have two or three solid repeaters than a
dozen where the maintenance is hit-and-miss and there's no one who
really cares whether they are up or not.

There must be a compromise between these two opinions. There cannot be

Hi again Mark,

Certainly there are places where there or only "one or two repeaters", but my
hypothetical example was built from my own local area where there are 108 pairs
assigned. If my PBI were implemented and the Repeater Council could harvest the
arbitrary 10% I mentioned, then there'd still be 97 legacy machines to choose
from, and 11 pairs opened for emerging technologies.

One of the several radio clubs which I am a member of maintains a
rather extensive UHF repeater system which usually sits silent except
for about a half-dozen of us during commute hours or when we are doing
some exercise like Field Day. If this was to "go away" (fat chance of
that, knowing the reality of the situation and the folks involved) the
local medical center where I am the Disaster Communications Team
co-manager would be without required ham radio backup. We went to
that arrangement when we found out in a real disaster last December
that the local ARES groups could not accommodate the type of traffic
that we needed because of their own overloads.

Consider the trap that the FCC's first-generation automated Spectrum
Management System fell into some 30+ years ago. It sat on Fire Radio
Service frequencies and reported no activity. Of course not - if
there are no fires there is no radio traffic, and the vast majority of
fire radio activity is with 5-watt on-scene HTs. Similarly, it
reported almost no Railroad Radio Service traffic in New York City -
where the monitoring was done during daytime and the bulk of freight
movements are at night. And to cap it off, it reported continuous
occupancy of a lot of channels in Chicago 24/7, until one of the old
hands at the Field Office listened and found out that it was a
defective electrical device throwing RFI into the air.

You assume that those repeaters do not have backup power. I found

out. Most of the repeaters that are reported "silent" are because
they are kept alive by a small group of people whose activity is not
always observed by the casual ham. I'm the trustee of two club
repeaters maintained by one of the other members who is a 2-way radio
tech. Our 2 meter machine is used all the time by ham-licensed
truckers driving up and down the Interstate. The other is used only
by the few club members who have the 223 MHz band in their radios. The
casual listener would consider that one "unused", which is not the
case.

Similarly, during the many hours each day that I spend in my Comm
Center at home - a cross between a home office, a library, and a ham
shack - I maintain a speaker watch on the UHF repeater that my other
local club uses for commute-hour rag chews and is available for use
for hospital disaster communications. Except for the commute hours,
it is "silent" but I'm there to answer any calls and to join in the
rag chews. That seems to be the norm for the "silent" repeaters in
this "no pairs available" area. We do have several where there's
pretty frequent use, though.

I am assuming that a repeater with ZERO activity is a repeater with no
one who cares about it. In one of your previous posts you mentioned a
repeater in your area which is "only" used during commute times and FD;
this is not zero activity and indicates that there is a core group of
people who care about the repeater.

The kind of repeater I'm talking about is one that might have been quite
active a decade ago, but has been running on inertia for several years.
Maybe it still responds to a signal on the input frequency, but the
chance of it having usable backup power is extremely low. Another issue
is potential damage during the disaster; if there is not a group of
people who use the repeater, no one will be there to make the
perhaps-trivial repairs necessary to get it back on the air.

The key word in your sentence is "used". "Zero activity" is
incompatible with "used".

I said, "I'd rather have two or three solid repeaters than a dozen where
the maintenance is hit-and-miss and there's no one who really cares
whether they are up or not." I did not imply that if a repeater is
silent that the maintenance is hit-and-miss. What I said is that if
there is not a group of people who care about the repeater, it's likely
to be useless in a disaster, and I stand by that statement.

Any repeater that has a regular group that uses it during commute does
not fall under the category of "zero activity", and obviously there is a
group of people who care about it.

Good. I think that perhaps you misinterpreted my initial comment to be
that a repeater needs to have constant activity to be viable, and that's
not what I was trying to say. I do stand by my initial statement that,
given the choice of a dozen zero-use repeaters or a couple of busy ones,
I'll take the lower number of busy ones because they will be more likely
to survive a disaster.

And again let me point out the difference between urban and rural
environments. The simple fact that you have a higher population density
almost guarantees that you have more people using the repeater(s). Of
course, if you have many repeaters, the person-per-repeater number may
be as low as ours.

Our situation here in rural Minnesota is rather marginal. We do have a
local club with a core group of people who care enough about the
repeater to keep it going. On the other hand, our UHF repeater has been
down for almost a year now, and somehow the group has not been able to
get it back on the air, primarily because one person has promised to
provide a new site for the repeater and has not followed through on that
commitment.

We had an actual disaster a few months ago, not in this immediate area
but in rural Minnesota. There was a need for ham radio communications
because the incident was "down in a hole" where cellphones wouldn't
work. (Floods often happen in river valleys.) The response was not
what it should have been. Part of this is due to the low number of
hams, and part is due to the lack of organization.

If we want to generate traffic on the repeaters, the simplest way is
to generate some traffic on them. Get a friend and talk on the thing.
Next thing you know, others will join you. If enough places do that,

I didn't make my point very well. We don't need to "generate
traffic", we simply need to clean out the dead "legacy" assignments
and free up room for things like DStar and other emerging
technologies.

I just had a look at our local (Minneapolis/St Paul) pair assignments.
In the 2M and 75CM bands there are 108 repeater pairs assigned. You
read right --- ONE HUNDRED AND EIGHT! Yet I can scan both bands for
hours on end and hear nothing.



I'm not sure that the idea of getting rid of analog repeaters so that D-
Star repeaters can be given those frequencies is really going to do
much. If your area has 108 repeater pairs coordinated, and no activity,
I suspect that a D-Star repeater will be likewise not have much
activity. At this time you would probably just have one more repeater
that isn't used.

Your area's problem is lack of interest, not too many repeaters. My
point is if Hams start using the repeaters, they might bootstrap
interest.

After interest is generated, then the possible next conversation might
be "Hey, we have that old repeater on the south side of town, maybe a
group of us can get together and go digital....

Respectfully no. my lack of communication skills is showing sorely.

What I am saying is that if the sum total of communications is Zero, no
one will use a new repeater, D-Star or analog.

Further, I am saying that if no one is interested, who among the
disinterested is going to put up that repeater?

Finally, if interest is generated, perhaps some of the interested will
remove that unused analog repeater, and put a digital one in it's place.

Or the condensed version:

An unused digital repeater sounds the same as an unused analog one. ;^)

Unless you monitor a frequency 24/7/365, it is impossible to claim

Hi again Mark,

Certainly there are places where there or only "one or two repeaters",


I wasn't talking about a place where there are only one or two repeaters.
I was talking about a place where there are a large number of repeaters,
but only one or two have a lot of activity. If you want to got through
and shut down the "inactive" repeaters so you can harvest the assigned
pairs, then you will wind up with not enough infrastructure when it is
really needed.

If my PBI were implemented and the Repeater Council could
harvest the
arbitrary 10% I mentioned, then there'd still be 97 legacy machines to choose
from, and 11 pairs opened for emerging technologies.


If there are 10% of those pairs truly unused, there doesn't need to be any
harvesting. Just use them. Who will you be interfering with?

QSL?


I verify this conversation took place.

If I lived in Resume Speed, Montana that might work, at least for awhile, if I

It would be far easier to connect a voice-activated tape recorder
(like a Sony TCM-37V recording walkman) to a scanner that was set to
scan just the frequencies that are suspected of being dead. Then, you
could document your results when claiming that the frequencies should be

Gentlemen;

The point to remember is that NO repeat NO one has a right to any
particular radio frequency. Even coordination does not grand any right
to a particular radio frequency, only license to use the frequency.

The repeater coordinator has a responsibility to insure that an
applicant really does intend to utilize the assigned radio frequency. If
the applicant does not do so after a reasonable time then the
coordination is or should be null and void. No, I am not going to define
reasonable.

It's like cell phone companies getting assignment to a block of 10,000
numbers and not using them causing the creation of a new area code to
free up new numbers. The FCC, I believe, has baned this practice.

Repeater Coordinators have a responsibility to allocate an extremely
scarce resource in a fair and reasonable manner. Those who get a
coordination just to have one and don't place equipment on the air, even
if they use it in a limited manner, do not deserve to retain the
coordination and the frequency should go to a new applicant.

Remember the FCC gives precedence to a valid coordinated applicant over
a claim jumper. But the coordinated applicant must be using the
coordination. Maybe applicants should report back to the coordinator
when the repeater is placed into service and when it is removed from
service for reasons other than routine maintenance to include damage due
to natural causes. This will keep applicants on their toes to keep their
repeater on the air and active.

97.205(c).Where the transmissions of a repeater cause harmful
interference to another repeater, the two station licensees are equally
and fully responsible for resolving the interference unless the
operation of one station is recommended by a frequency coordinator and
the operation of the other station is not. In that case, the licensee of
the noncoordinated repeater has primary responsibility to resolve the
interference.

So does 97.205(c) give the licensee of the coordinated repeater any
rights? Seems to me that it does.

We can go on and on with "could of" and "should of", and with discussion
of what "harmful interference" means. The bottom line is that frequency
coordination is recognized in the regulations and thus it's not a
prudent idea to simply ignore it and pick a pair for your new repeater.
