System Notices |
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.
Report interference to
Cass Cable at
800.252.1799, or to the appropriate cable provider. |
ALL
POINTS BULLETIN:
3/01/2010
(Continuing 05/2010) |
DISCONTINUE
using the LAW Legacy Mobile TX
Protocols!
(De-program the former 155.910 114.8 Mobile Tx Protocol; the 154.785
114.8 base transmit protocol is unchanged.)
This receive point is being
DISCONTINUED and will
not be supported after Thursday, April 15th, 2010.
While the receiver may remain
active, it should be considered
unreliable.
The 155.910 mobile TX frequency is being assigned to other uses-
continued TX by mobile users attempting to communicate on LAW
and 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 05/2010) |
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. |
WARNING NOTICE:
3/23/2010 |
A foreign transmitters are causing
System Interference; this issue is being investigated.
-
Macoupin County Sheriff is
(legally) causing intermittant interference on LAW.
- Griggsville PAGING
continues to have frequent short unintended transmissions.
- Some mobile to base
traffic on ALPHA, BRAVO or LAW may have sufficient interference to
cause poor audio.
|
ADVISORY NOTICE:
7/9/2009
(Continuing 05/2010) |
The area along IL-100 between Pearl
and Bee Creek and west to Spring Creek Road, and along Bluff Road
between Pearl and Montezuma is still under-served by any Pike System
receiver. Portable users may find spotty coverage in some or all
locations. Mobile users may find poor portable coverage and may be
required to use or relocate their vehicle for reliable operation. This
was a known gap in the original system design and additional coverage
equipment has been authorized and will be installed with an on-line date
of late spring 2010. |
Notice:
3/22/2010 |
Griggsville BRAVO transmitter
operation has been fully restored. |
Notice:
3/9/2010 |
Trouble has been observed with the
LAW/Pea Ridge transmitter hanging 'up' after being instructed to stop,
resulting in multiple base transmitters being active at the same time.
This trouble was cleared Tuesday afternoon. |
Notice:
3/9/2010 |
Problems were found late Friday 3/5
and corrected Tuesday 3/9 relating to reception of System signals by the
PKSD Office receive site. After repair, this site now handles Pittsfield
area portable-to-system uplink traffic at least twice better than as
designed. |
NOTICE:
10/23/2009 |
Hull EMS Crews are cautioned that
Pages for New Canton EMS (not fire) will not activate their
radios/pagers IF they are set to HULL-FIRE-ONLY mode. |
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-north
areas may find that voting may move from Hull to EL Dara without
warning, however Kinderhook area reception of either voted site should
not be an issue. |
