• The Radio Shack PRO-652 appears to be similar to the Whistler WS1065, but the firmware is not compatible.
• The PRO-197 was manufactured for Radio Shack by GRE America Inc.  Later, Whistler supplied an equivalent unit to Radio Shack as the PRO-652.  The Whistler WS1065 is the later equivalent radio.

Q.)  How do I get the PSR-500, PSR-600, PRO-106 or PRO-197 to output control channel data to decode?

A.) The PSR-500, PSR-600, PRO-106, and PRO-197 have the capability to send control channel data to the PC/IF port anytime the scanner is monitoring a 
	control channel.  While this data may be decoded by Pro96Com, this data stream will be lost by Pro96Com whenever a voice channel becomes active, 
	or conventional, search, or sweeper objects are being scanned. In addition, if you are monitoring a multi-site system, Pro96Com will constantly 
	reload the data each time it finds a new site.

    To get a steady stream of data, these radios need to be placed into analyze mode on an active control channel. There are two ways to get into analyze mode.

    In manual mode, locate a talkgroup that's a member of the system you want to monitor. Once located, Press the F2 (TSYS) key, then the F3 (Analyz) key. 
	Using the up or down arrows, locate an active control channel. When you see the decoded information on the screen, the scanner is ready to send the 
	control channel data.

    In scan mode, you can wait for a talkgroup on the system to become active, at which point you can follow the same procedure (F2/F3) to place the scanner 
	in Analyze mode.
