This was posted on the ScanIowa list back in April 2001. The database did have a bad tone listed, and I have corrected it. I do know that up here they use a tone of 167.9.
IOWA CHANNEL
Purpose
The purpose of the IOWA channel is to provide inter-agency communications
between public safety and non-public safety governmental agencies in the
state of Iowa. The IOWA channel is different from the Mutual Aid channel
(155.475) in that it allows non-law enforcement agencies access to a common
channel.
Eligibility
Any governmental agency in the state of Iowa may apply to the Iowa Department
of Public Safety for a special use agreement to operate on the IOWA channel.
Governmental units may include sheriff, police, fire, DOT, public works and
other local government agencies.
Rules
1. Government agencies may only operate mobile and portable radios on the
IOWA channel. Base stations and fixed stations will not be permitted.
Mobile repeaters or crossband repeaters may be permitted as approved by
special use agreement.
2. The IOWA channel frequency is 151.475 with a CTCSS tone of 167.9 Hz.
3. The IOWA channel shall be analog FM and shall not be encrypted.
4. The FCC license will be held and maintained by the Iowa Department of
Public Safety.
5. The IOWA channel shall be used primarily for emergency communications
between governmental agencies. Brief and occasional non-emergency
information is permitted. EMERGENCY COMMUNICATIONS SHALL ALWAYS BE GIVEN
PRIORITY OVER ALL OTHER RADIO COMMUNICATIONS.
6. The IOWA channel shall not be used for routine traffic between mobile
units of the same agency.
7. Counties bordering Nebraska and Minnesota should use caution not to
interfere with operations in neighboring states. The special use agreement
may restrict operations in certain locations to ensure the state of Iowa
remains a good neighbor.
8. The IOWA channel may be installed in non-governmental mobiles such as
private ambulances, public utilities, tow services and others, which in an
emergency would require cooperation and coordination. Such operation on the
IOWA channel shall be limited to within the geographical boundaries of the
jurisdiction involved. Communications from non-governmental mobiles shall be
limited to the official activities of the governmental agency involved. The
agency involved shall be responsible for the proper operation of the mobile
unit under their jurisdiction.
9. The Iowa Department of Public Safety LEATAC committee shall approve the
special use agreement requests and resolve any conflicts that may arise.
