Update
on Repeaters
Many enhancements to the
Tidewater Wireless repeaters have been accomplished over the past several
months. We have also expanded the
number of repeaters we operate. Work
continues to make the systems even better. Many
thanks to all who have helped, whether at one of the repeater sites or by
helping with signal and audio checks from various locations.
Special kudos to KO4FR, N2NMH, and WA4WX for the substantial amount of
time and effort expended in support of the repeaters.
The
Norfolk
145.33 and 442.95 repeaters are running on new equipment and share the same
controller. This has enabled the two
repeaters to be linked together full-time. They
may also be operated as stand-alone repeaters when the need exists.
The 145.33/442.95 system has a weather alert receiver connected, but is
not yet fully functional. The
repeater controller has a digital voice recorder that can be used to send Tail
Messages. Such messages are
currently set to sound at intervals no sooner than 15 minutes.
The 145.33/442.95 system includes a remote base that is still being
worked on. Band modules include 440
MHz and 6 meters. An EchoLink
connection is now also available on this repeater system.
The autopatch is being adjusted, so you may have better success making
calls on 147.375 until the adjustments have been completed.
The repeater transmits CTCSS 131.8 and may also be set to require a user
to transmit the same tone to activate the repeater.
The
Norfolk
147.375 repeater is the newest Tidewater Wireless repeater.
It has a 440 MHz remote base as well as autopatch.
The antenna is about half the altitude as the one on 145.33/442.95, so
the range is somewhat less. The
repeater transmits CTCSS 131.8 and may also be set to require a user to transmit
the same tone to activate the repeater.
The 145.17 WA4ZUA repeater should soon be on the air in
Hampton
. This repeater will not have
autopatch capability, but will otherwise function the same as the W4VB
repeaters.
If you desire an autodial slot for the 145.33/442.95/147.375 repeaters
please contact us with your request. Repeater
supporters receive an unlimited number of autodials.

Operating Modes
Tidewater
Wireless repeaters have several different operating modes, often identifiable by
a different courtesy tone. The most
easily recognized are the Normal Mode (M1), Rush Hour Mode (M2),
Net Mode (M5), and Red Cross EchoLink Net Mode (M6).
Here are some of the characteristics of the different modes:
Normal Mode (M1): Used on all
of our repeaters when other modes are not scheduled or activated.
Has a 3-tone burst for the courtesy tone.
Rotates between several different IDs.
Tail Messages may or may not be activated by a control operator.
Rush Hour Mode (M2): This mode
is set on weekdays
5:30 am-9:00 am
and
3:30 pm-6:30 pm
. It uses a distinctive courtesy
tone and has a Tail Message announcing the time.
Other Tail Messages may or may not be activated by a control operator.
This mode is designed to remind users of the potential for an influx of
mobile stations on the repeater while traveling the area roads and highways.
Net Mode (M5): This mode is
used
7:20 pm-8:15 pm
on the 145.33/442.95 repeater system to facilitate the RASON Net
Monday-Wednesday and the Norfolk ARES Net on Thursday.
A single-tone burst is used for the courtesy tone, however, a different
tone is used depending on whether the user is transmitting on VHF or UHF.
Once you recognize the two sounds you will be able to tell which repeater
the person is using during the net. A
single tone courtesy tone on any of the Tidewater Wireless repeaters may
indicate a net in progress. Control
operators have the capability of activating the Net Mode whenever needed.
All Tail Messages are normally off while in Net Mode and most IDs will be
in CW.
Red Cross EchoLink Net Mode (M6): This
mode is used at
9:00 pm
on the 145.33/442.95 system to facilitate an EchoLink connection into the Red
Cross Communicators Net. This mode
does not use a courtesy tone and has a very short repeater carrier hang time.

EchoLink
EchoLink is a Voice over IP (VoIP)
system established for amateur radio operators around the globe.
Amateurs may connect to the system from their computer or by way of an RF
link connected to the system. RF
links may be through a repeater or on a simplex frequency.
The 145.33/442.95 repeater system has an EchoLink connection known as
W4VB-R and EchoLink Node 311763. Amateurs
from around the world may connect to us through this node and call out through
the repeater. All amateurs on the
repeater are invited to communicate with stations connected via EchoLink.
Users of the 145.33/442.95 repeater system desiring the ability to
connect to specific EchoLink stations on demand from over the air may email us
in order to make arrangements for a special code.
Additional EchoLink information is available at http://www.echolink.org

Providing assistance to visitors to the area is encouraged, however, the
authorized user must dial the codes for the visitor.
