	Yes, it's still true. The first IF frequency in crystal
	controlled Bearcat scanners is 10.8 MHz. The synthesized
	bearcats have first IF's of 10.8 and 10.85 MHz (e.g. early
	and late BC-250).

	The Compuscan (TM) demonstrated to our club was driven by
	an IBM PC. This setup operated about as fast as a BC-250,
	a reasonable speed.
	A review of the Compuscan in Monitoring Times complained 
	of slow performance when a C64 was used as the controller.
	The receiver board in the Compuscan is the same as used
	in the BC-300 and BC-350. The feature board differs in
	these scanners.
