Re: [Repeater-Builder] missing posts

2006-05-08 Thread Bob M.
I posted one message to the group Friday morning. I
never got my copy as a subscriber. It IS there in the
group's messages. In fact, on Friday, I never got a
single message after 7am for the rest of the day. I
got a few on Saturday and a few more on Sunday. Things
seem to be back to normal this morning, but who knows.
Even my regular e-mail was rather quiet. I wonder if
it had something to do with Cinco de Mayo???

I'm sure that complaining to Yahoo will get the usual
automated reply. I don't think messages were delayed;
they were just never sent out. They seem to have that
problem a lot.

Re: Crossband/Portable repeaters

-  Here in Colorado, we have two 2 Meter pairs designated for statewide 
use for
   portable/emergency/special event repeaters. These pairs get used to 
fill in the dead spots when
   emergencies occur. A number of clubs and ARES groups have portable 
repeaters set up
   on these pairs.  (Good band planning by whoever put these in place 
years ago.)
-  Some of the emcomm folks use dualband transceivers with crossband 
repeat as a inexpensive way
to extend radio range (often used to extend HT range from inside a 
building or other bad spot).
These radios don't meet the letter of the law (FCC regs) with regard 
to identification (my opinion,
you mileage may vary.)
 - We do not have any designated frequencies for crossbanding to 440 MHz 
in the bandplan.
Most people just find some lightly used uhf simplex frequency.
 - If conventional transceivers are used, the power needs to be reduced 
or additional cooling
supplied due to 100% duty cycle operation.
 -  I constructed a crossband repeater using two transceivers and an 
NHRC-6 controller that knows
how to handle the ID of two transmitters appropriately (most 
repeater controllers do not).
http://www.nhrc.net/nhrc-6/
 -  One issue with a vhf/uhf crossband repeat set up working into a 
repeaterthe repeater transmitter
 must drop before the crossband repeater can turn the link around. 
Shortening the hang time on
 the conventional repeater (or using CTCSS that drops with the 
received signal) helps this issue.

not know it. That said here in some parts of Florida there are a number of

push for a statewide pair or frequency and instead try pushing a frequency 
yourself ! People have a habit of forgetting past history when repeaters in 
an area are down for any number of reasons and that having the ability to 
continue to communicate is very important. When the power goes down after 
storms and it stays down for a month and sometimes more these repeaters come 
in handy. I have a UHF GMRS mobile repeater just for this purpose. While 
mine is duplex I see a good need for simplex repeaters as the radios are 
real cheap! Cross Band as well!  A lot of the repeaters are on commercial

Re: [Repeater-Builder] Portable Repeaters

2006-05-08 Thread Dick
Steve et al:

The various amateur repeater coordinating groups have no official FCC 
authority
or mandate to control spectrum or issue repeater pairs.  As a practical 
matter,
however, the FCC will almost always support a coordinated repeater over a
non-coordinated one in matters of interference.  This is in keeping with the
FCC's mandate to prevent interference.  Fortunately, the vast majority of 
hams
are a cooperative lot and generally work with their local coordination group 
to
keep repeaters from causing interference to each other.

I have a portable UHF repeater on GMRS and one in the ham band and have used
them where I live.  So far, so good and no problems.

By and large, the system works quite well.

 These radios don't meet the letter of the law (FCC regs) with regard

I have one set up in my vehicle to help me get into our UHF system from
inside a building. It uses a 420.something input and a 443.something
output. I have a extra memory position set up on the handheld that listens
to the system output and talks on the 420 channel. We are coordinated
on that 420 channel as a link frequency and the receiver that hears that
frequency is over 100 miles away and is on a directional antenna pointed
at the mountaintop that the repeater is on, so it's not going to hear my HT
inside a building. I'm the only one who is going to use that mobile extender
and I am sure to ID it with through the WA6ILQ mobile repeater as needed.

However Kevin has banned rules and regs discussions on this list for good
reason - they generate a lot of heat and fire and discontent and nothing gets
resolved - and this is getting close to that area so I'm going to 
drop the regs
topic with this posting. Any regs followups to personal mail, or technical
followups to the list.

  - We do not have any designated frequencies for crossbanding to 440 MHz
in the bandplan.  Most people just find some lightly used uhf 
simplex frequency.

I've been known to use a repeater input frequency from some out-of-the-area
system (with permission from the system owner) and use a different PL tone
on top of that. For a long time I had a roll-around Pelican case (think of a
Samsonite rollaround suitcase that's the width of a rack panel and a 
foot thick)
with a 25w Micor mobile (switchable between the two local test pairs) with
a duplexer, a Scom 7K and a Optima sealed battery in it.  Roll it into a
convention hotel room, stand it in a corner opened up for ventilation, hook up
an antenna to the duplexer (a 6 mag mount stuck to the bottom of a metal
trash can lid and hanging upside down from a top floor room balcony gets
out a lot better than you would think).

  - If conventional transceivers are used, the power needs to be reduced
or additional cooling supplied due to 100% duty cycle operation.

A forgotten fact is that 25w Micor mobiles are continuous duty.

  -  I constructed a crossband repeater using two transceivers and an
NHRC-6 controller that knows
 how to handle the ID of two transmitters appropriately (most
repeater controllers do not).
 http://www.nhrc.net/nhrc-6

A good tip - I'd forgotten that.
BTW the -7 will also.

-  One issue with a vhf/uhf crossband repeat set up working into a
repeaterthe repeater transmitter
  must drop before the crossband repeater can turn the link around.
Shortening the hang time on
  the conventional repeater (or using CTCSS that drops with the
received signal) helps this issue.

We ran into that problem in one of the 1980s Rose Parades... I forget
which year... the floats are built at over 15 locations and have to convoy
in (some from 40 miles away) and arrive at the formation area in the
proper sequence. Formation is on a city street and one float passing
another is difficult - ever try and parallel park a 5-ton float that's 50 feet
long and has a 300-degree blind spot? My assignment was at one of the
float construction areas and could not get into the main parade control
147.27 repeater from there... I had a 440-to-2m crossband repeater in
my car (at that time it was two HT-200s) and the guys at Parade Control
had to wait for the system to completely drop out before I could answer
a call.
A while later another ham showed up with a 10w mobile and a gellcell
in a backpack complete with an 18 spike antenna on a microphone
gooseneck strapped to one of the shoulder straps.
A few years later an outbound CTCSS encoder slaved to inbound COR
was added to the repeater to support the crossbanders
I wish that more repeater owners would add that.

The repeater site is not shared. I have now tried everything I

Re: [Repeater-Builder] Portable Repeaters

2006-05-08 Thread wa6rqd
Ronny,
It does not seem like a good idea to me to pop up on an untested 
channel(s) during an emergency. It would make sense to me to find a 
usable pair before the s**t hits the fan. Things are stressful enough in 
an emergency without trying to move both the repeater and then get all 
users to move without a large hole in connectivity. There is a good 
reason amateur emergency response groups practice _before_ they are 
really needed.


Paul,
One problem with the cross band approach is users with 440 HTs will need 
to wait for the two meter repeater drop delay to run out before they 
transmit. This also can be stressful in an emergency. You can get around 
this if you have the two meter repeater talkback encode PL only when the 
receiver squelch is open and then make the crossband box decode on two 
meters.

There are, of course, coordination problems with portable duplex

RE: [Repeater-Builder] Portable Repeaters

2006-05-08 Thread Eric Lemmon
Paul,

When you push for a wide-spaced portable repeater pair on 2m, suggest a
separation of at least 3 MHz.  The reason is that you can buy compact base
station duplexers that are specified for 3.0 MHz spacing, but the
performance rapidly deteriorates as the spacing is reduced below that point.
I bought a Celwave 5085-1 duplexer that was factory tuned to a 2.655 MHz
split, and it works okay with a 10 watt R1225 repeater, but it took some
tweaking.  The entire repeater fits into a rugged fiberglass case that is
less than a cubic foot in volume.  I hope to complete the final version
shortly.

It will be a challenge to create a 3 MHz pair in only 4 MHz of spectrum, but
it can be done.  Let's not forget that the purpose is to support *temporary*
communications of an emergency nature.  While it would be nice to have a
pair permanently set aside for this purpose, I'll bet that a true emergency
will trump any other claim to existing frequencies.  If the PL encode and
decode tones are intelligently selected, any interference to established
repeaters should be minimal to nonexistent.  If the portable repeater is
positioned in the area where radio comm is needed, low power works wonders!

We can't even get real emergency groups around here to use STANDARD

Color me VERY skeptical that any more than a few people will ever truly 
use a wide-split portable VHF repeater in a true emergency.

Overloaded, stressed out people, don't respond well to dig out your 
manual and figure out how to program in a 2.655 split repeater.  And a 
large number of people wouldn't or couldn't -- sad, but true.

Plopping a simplex repeater or even a backup real repeater on the 
output of a dead repeater affected by the emergency... (no power or 
whatever other damage it suffered)...

... right on the regular old coordinated pair... (once you know the real 
repeater there is dead and down for the count)...

... is SO much more likely to be effective -- that anything else pales 
by way of comparison.

We hams over-engineer this stuff, constantly.

Some of the silly stuff I've watched so-called emergency planners come 
up with over the years is amazing.  NONE of it can be reasonably done in 
a REAL emergency, and isn't, usually.

(Ex: Yeah, everyone who hasn't used packet in 10 years is all of a 
sudden going to fire up the Statewide backbone, put a couple more BBS's 
on the air, and everyone's going to remember how to set up their user 
stations perfectly and no one's going to hog the channel or interfere 
with anyone else... Packet always comes up as one of the big answers 
ES people seem to like, and NEVER EVER really USE.  We had a 1200-baud 
digital-regenerative repeater on the air from a site that had 5W outdoor 
150+ mile coverage, and it was on the air for 5 or more years.  Know how 
many users it had?  Maybe 5.  Was it the perfect answer to the hidden 
node syndrome of a busy packet channel?  Yes.  Want to know why ARES 
didn't use it the two times in that 5 years they fired up packet for a 
real emergency?  PRIVACY CONCERNS!  They could make the hops they needed 
DIRECT so there the repeater sat, unused.)

The reality of emergencies is -- real emergencies -- people will 
congregate on frequencies they're used to using -- even if just on the 
output frequency -- and by putting something THERE in a REAL emergency, 
it is 100% more likely to be effective and USED than anything else.

In fact, that's my experience... the gaggle of hams wanders around 
kerchunking until they find the best coverage real repeater on the air 
that covers the affected emergency area, and then that repeater 
instantly becomes the busiest repeater around.  No matter if it's the 
worst-engineered, or the best... if it's on the air when the 
big-bad-high-sites are down, and it covers the affected area -- whoever 
built it better hope it has the ability to handle 100% duty-cycle.

Just common sense.  People are going to use what they're used to, so 
don't over-engineer an emergency solution -- build one that 
capitalizes on people's repetitive and habitual nature.  Build emergency 
RF plans SIMPLER not more complex.

Eric -

Thanks for the comments on duplexers. When I started this in January,  
I remember reading some comments about some duplexers getting out-of- 
tune from bouncing around (mainly in shipping) and that's what got  
me thinking about simplex repeaters and, now, about cross-band  
repeaters. Is subjecting the duplexer to vibration and shocks in a  
truck on a rough road really something about which to worry?

One of the comments I received when I proposed using simplex  
repeaters was that, if a fixed-repeater went off the air because of  
power failures, it would be possible (with the permission of the  
repeater owner/trustee) to tune the simplex repeater to the fixed- 
repeater frequencies as a temporary measure until the fixed-repeater  
could be returned to service. What do you think of that?

You did a great job of answering the question I posed to Eric before  
I read this. Parking a standby itinerant repeater on a pair of  
frequencies that are temporarily down due to the emergency does make  
a lot of sense. Hopefully this discussion will spark some inter- 
association cooperation and exercises. In an emergency, hams in the  
area may have serious problems of their own that demand attention and  
the solution to communication problems will be resolved by hams from  
neighboring areas who move their time, talent, and equipment in just  
as volunteer firemen move up to man vacant fire stations while the  
local firefighters are busy elsewhere.

Your comments about preparedness are right on the mark. I took the  
trouble to become a certified planner in connection with my NYSDOT  
career but I know a lot of other planners who ought to be  
certified (and not with the AICP designation). A week or so ago, I  
had almost decided to forget about providing a standby repeater of  
some sort in my Sprinter ARK but this discussion has revived my  
plans and I'm very appreciative of the response from all you experts.  
My telecommunications background goes back over fifty years in the  
telephone business where I worked on a lot of magneto crank phones  
and step-by-step dial systems and I've only been a ham since January  
when some other hams scoffed at my idea of furnishing a GMRS repeater  
that volunteers who were not hams but had access to some bubble-pack  
hand-helds could use.  You folks have come up with a lot of great  
ideas that I plan to discuss with the repeater coordinators and I  
need all the help I can get. Thank you all!

RE: [Repeater-Builder] Portable Repeaters

2006-05-08 Thread Eric Lemmon
Paul,

Full-size BpBr cavity duplexers can easily be detuned with rough handling,
especially when the box is dropped on its side- which puts sideways shock
loads on the center tuning element.  Notch-only duplexers of the mobile
type are, by design, far more resistant to vibration and rough handling.
The Celwave 5085-1 duplexer I cited is a notch-only duplexer that is about
50% larger in all dimensions than a typical mobile duplexer, but it should
be nearly as rugged.  I don't expect this portable repeater to be bouncing
around in the bed of a pickup; it will likely be strapped to a shock-mounted
storage shelf in my RAV4, along with magnetic mount antennas and a
telescoping mast.

A simplex repeater on an existing repeater pair is an excellent idea.  I
already have one in service, being tested on a coordinated pair assigned to
me.  It is a Motorola SM50 VHF radio connected to a Zetron 19B Simplexor
simplex repeater controller.  It listens on the repeater input frequency and
plays back on the repeater output frequency.  A Comm-Spec ID-8 performs the
identification functions while the repeater is in use.  It gets used a lot

admit that a simplex repeater (isn't that an oxymoron?) gets to be tiresome
to use real fast, and some users get annoyed by hearing everything twice.
But, hey, in an emergency it works.

One of the posters commented that it would be chaos while everyone tried to
reprogram their radios to the special wide-split portable repeater
frequency.  Not!  The majority of the Hams who will use this portable
repeater are fully-trained ARES members who test their equipment on a weekly
basis on several nets, and all of their personal radios are pre-programmed.
One of the local ARES groups has a cache of Motorola HT750 portable radios
which are already programmed with every local repeater, including the
wide-spaced portable.  We take emergency preparedness seriously in my neck
of the woods, and we don't expect or need to have a sudden influx of
clueless people who don't know how to program their own equipment.  It is a
requirement that each ARES member have in his or her possession a valid
Disaster Services Worker identification badge issued by the County Office of
Emergency Services.  Mandatory refresher training, including CPR, is
routine.

Thanks for the comments on duplexers. When I started this in January,  
I remember reading some comments about some duplexers getting out-of- 
tune from bouncing around (mainly in shipping) and that's what got  
me thinking about simplex repeaters and, now, about cross-band  
repeaters. Is subjecting the duplexer to vibration and shocks in a  
truck on a rough road really something about which to worry?

One of the comments I received when I proposed using simplex  
repeaters was that, if a fixed-repeater went off the air because of  
power failures, it would be possible (with the permission of the  
repeater owner/trustee) to tune the simplex repeater to the fixed- 
repeater frequencies as a temporary measure until the fixed-repeater  
could be returned to service. What do you think of that?

Randy,

I believe you have a 30 watt radio intended for the 450-470 MHz band.

Thanks for the education on duplexers. I had planned to stow the  
repeater in a Pelican case but some of our New York roads are a  
little rough especially if we're looking for a high point in the  
vicinity of an incident. Your comments on preparedness are well- 
presented. If we want to do a job right, we need to plan and train  
and practice

Well, you've gotten me all fired up again on the simplex repeater  
idea. Hearing everything twice isn't a bad idea. In the telephone  
business, we solved a lot of operator problems by service observing  
that consisted of recording a sample of each operator's calls and  
then calling them in and asking them if they'd like to hear what they  
sounded like before we erased the tape. We didn't need to say a word  
and the look on each operator's face as they said Oh, no! or Is  
that what I sound like?' or Did I say that? showed it was the best  
training they could ever get.

 Paul,

 A simplex repeater on an existing repeater pair is an excellent  
 idea.  I
 already have one in service, being tested on a coordinated pair  
 assigned to
 me.  It is a Motorola SM50 VHF radio connected to a Zetron 19B  
 Simplexor
 simplex repeater controller.  It listens on the repeater input  
 frequency and
 plays back on the repeater output frequency.  A Comm-Spec ID-8  
 performs the
 identification functions while the repeater is in use.  It gets  
 used a lot
 by Hams who want to hear how their radio sounds.  I will be the
