It's fairly simple to equip the COM215 and the identical Albrecht AE-60T, Realistic PRO-2036 and Uniden Bearcat BC890XLT with a discriminator output. The interior of the scanner is spacious, and DIL IC's are used.
The receiver IC is a JRC 3359. Undoubtedly, this is a clone of Motorola's MC3359. The unfiltered audio can be found on pin 10.
