Now manufactured by Castle Creations, the Berg Microstamp 4L is even smaller and lighter than the previous version. This full-range, 4-channel receiver has an on-board microprocessor with new software for nearly glitch free performance. The "True Digital Signal Processing" (TDSP) software uses adaptive algorithms to filter out invalid pulses for virtually glitch free performance even in harsh RF environments like indoors. In addition, the receiver has "Transmitter Signal Recognition" (TSR) software. Upon power up, the receiver learns the characteristics of your transmitter like positive (JR/Airtronics) or negative (Futaba/Hitec) shift, number of channels, trigger pulse length and approximate frame rate. Once learned, the receiver locks onto your transmitter and rejects signals from other transmitters that have different characteristics. Finally, it has a programmable fail-safe function. In the event of a signal loss, it can be programmed to hold the last good servo positions, and upon extended signal loss, automatically switch to pre-programmed servo positions that you can set, for example, to cut the throttle, apply slight up elevator and left rudder to perform a gentle descending circle.

Triple tuned RF circuitry with steep flank 8 pole IF ceramic filter set
TDSP filtering in the microprocessor decoder, with adaptive algorithms based on signal to noise ratio of the received signal
