System Notices |
WARNING
NOTICE:
HIGH POWERED
MOBILE RADIO FAILURES
(Permanent Warning) |
Alpha, Bravo and Law are designed
to operate properly region-wide using low-powered portable radios. Using
a high powered mobile to communicate short distances WILL FAIL
due to the excessive RF radiation from the high-powered mobile
overloading nearby receivers to the point they cannot hear tower
repeaters. Also,
automatic repeater selection is based on mobile transmitter signal
quality as received by the system; use of high powered mobiles may cause
the system to vote to a distant transmitter rendering local
communication difficult. Raytheon/JPS is presently modifying their
voting firmware to improve this situation.
Users are advised to use
mobile ERP's of less than 25 watts whenever possible. In this case more
isn't better, it is absolutely much worse and may fail entirely. |
INFORMATION:
12/21/2010 |
Over the past month, Monday Fire
Dept. test pages have been reduced from 10 sequences to five, with
multiple agencies in each. This has streamlined the weekly test process.
Users are cautioned that test
page signaling is only for fire
departments; end users using EMS page signals for fire alerting will
not be signaled by the new test pages.
Actual pages for emergency
services are unchanged. |
ADVISORY NOTICE 12/20/2010
PEARL SITE NOW ONLINE |
The Pearl receive site is on-line as of last week. No user intervention
is required; the system will simply work better from the South Eastern
parts of the region.
Users may find that locations that
previously voted to the El Dara site (or didn't work at all) now vote to
the Pleasant Hill site.
Final adjustments will take a few
weeks of actual use to iron out, and the system may mis-vote from some
locations. Users are cautioned as always to simply use correct (and
patient) radio procedures. Please document any problems with mis-voting
and forward them in written form to the ETSB for resolution.
PAGING IS UNAFFECTED BY THE NEW
SITE! |
INFORMATION
12/01/2010
MICROWAVE IMPROVEMENTS |
The Microwave improvements have been completed, with much improved
reliability, and serviceability. Rain/weather related system degradation
has been all-but eliminated. |
ADVISORY NOTICE
10/25/2010,
Status Updated 10/29/2010 |
The Pea Ridge Site was off-line during the last week of October due to a
Microwave antenna failure. From 10/26 through 10/29 Pea Ridge was
temporarily set as a stand-alone repeater on BRAVO only. BRAVO was
intentionally disabled at all other sites. This is standard fail-safe
procedure.
This Pea Ridge Microwave system has
been upgraded ahead of schedule. The fault was repaired on Friday 10/29
and the entire system returned to normal operation. |
Policy,
Use of LAW Roam
(Permanent) |
Per the Pike County Sheriff:
Transmitting on LAW is restricted to Commissioned Peace Officers, Fire
Chiefs, or from authorized Emergency and Government-owned Vehicles. The
ability to transit on LAW Roam shall be disabled in all other radios,
including portables and mobiles belonging to Non-Commissioned First
Responders. Contact Sheriff Petty for authorization. |
ALL POINTS BULLETIN:
3/01/2010
(Permanent Change) |
(De-program the former 155.910 114.8 Mobile Tx Protocol; the 154.785
114.8 base transmit protocol is unchanged.)
This
155.910
mobile transmit frequency has been
DISCONTINUED.
The former mobile TX
frequency is being assigned to other uses- mobile users attempting
to communicate on LAW by transmitting on 155.910
Continued use will also cause problems in other unrelated systems.
Local and visiting agencies
wishing to use the LAW channel MUST use the 'new' (March 2008) mobile
transmit roaming protocols of 159.1800 20K0F3E 123.0 CTCSS. |
WARNING
NOTICE:
7/9/2009
(Continuing 11/2010) |
SEVERE
interference caused by solar activity / tropospheric ducting will
continue to cause poor performance of the system with the worst time
periods around dawn and dusk. This issue will continue for the
forseeable future.
Atmospheric conditions cause signals from licensed users located many
hundreds of miles away and operating on our same frequencies to hit the
Pike System receivers at levels at or greater than our own local users.
Expect noise/static, 'foreign' voices or other unusual phenomenon during
these periods. |
ADVISORY NOTICE:
5/2010 |
Users and our own investigation
have shown local cable TV providers to be leaking TV audio from their
'closed' cable distribution system, This locally affects frequencies
between 155.6 and 155.8MHz. Use of the appropriate receive CTCSS codes
will reduce the nuisance audio but not eliminate the harmful RF
interference from leaking Cable TV systems.
The Pittsfield system is
known to interfere with Adams Sheriff on 155.740 and V-CALL (aka 1CAL10)
on 155.7525 by leaking TV-Ch20, QVC. The 127.3 CTCSS should be applied
to Adams Sheriff. The national standard for V-Call is CS receive and
156.7 CTCSS TX. Providing all transmitters are properly programmed with
the 156.7 TX CTCSS, adding the same CTCSS to the RX frequency will
remove the nuisance interference, but users should be cautioned that
some vendors fail to program their transmitters with the NPSTC required
156.7 CTCSS, so open monitoring may be required. |
NOTICE:
8/1/2009 |
Numerous radios supplied by vendors
other than B-K Electric have been found with incorrect programming on
Alpha/Bravo/Law Transmit. These three channels DO NOT use the same CTCSS
tone for TX and Rx. Alpha/Bravo are narrow-band 11K2F3E channels and
will not perform properly in 20K0F3E wide band mode. Please advise your
vendor to download the latest
TECHNICAL
STANDARDS (link)
information and verify that
their products are programmed as required. |
INFORMATION:
7/9/2009 |
The Baylis Receive site is fully
operational on Alpha/Bravo/Law. Mobile users in the Kinderhook-northwest
areas may find that voting may automatically switch between Hull and EL
Dara without warning, however Kinderhook to Barry area reception of
either voted site should not be an issue. |
