8 Upgrade Ideas for Operators

Emergency Management Operators
Sterling Heights, MI
High AM Radio Performance Antenna
Increase your station's signal level.
Some operators may be able to increase their station’s signal levels by substituting the HPR.0990 Antenna for their existing one. Inquire with Information Station Specialists if there is an opportunity for you station to take advantage.
See details about the HPR.0990 Antenna.
2 HQ5.1 TIS Audio Processor  
Audio Bandwidth Upgrade
Give your station a more natural sound.
Add a 5000 Hz audio bandwidth filter or processor to your system’s audio chain to make broadcast quality more natural – like conventional broadcasters.

This is an upgrade usually performed in conjunction with the addition of a high quality IP.76 Digital Message Player and Professional Recording Services (listed below).

If your system was installed after 2015, you already have 5000 Hz bandwidth capability built in.
See details about the HQ 5.2 Broadcast Quality Audio Processor.
See also the HQ 5.0 Audio Filter webpage.

 NX8R Digital Message Player
Add Telco redundancy and maximize phone-based broadcast programming.
A digital message player controlled by telephone (and locally) is an important redundancy on information radio stations that are used for emergencies. It can also be the primary means of program management for stations that only have telephone line connectivity. The NX8R Digital Message Player provide the means to those ends. As an upgrade to an existing player, it works on the same convenient protocols as earlier the IP8 or AP55 Digital Message Players with a quantum-leap in performance:

3 hours of recording time and up to 1,000 messages. (The legacy AP55 Player has 14 minutes and 250 messages, maximum.)


Flash memory means all programming is safe from power loss.

A 16-bit recording rate makes messages sound better.


NX8R can handle two live feeds from sources such as NOAA, PCs, CATV, etc.

Station ID

The station identification plays automatically every half-hour as required by the FCC.


If you lose your telephone lines in an emergency, NX8R offers control by VHF radio.

TMS.020 Digital Audio Management System
Add convenience, quality and network connectivity.
The TMS.020 Digital Audio Management System can be remotely managed via a modern web browser (audio uploaded, deleted, triggered or assigned) or by use of a physical control and screen. No special software or computer type is required - just a modern browser. Audio playback can also be triggered or stopped by simple HTML CGI commands.
