Released toward the end of the AM era, the MK II was a modernized version with improved performance. Power Output: The RF output was significantly boosted to approximately 20–25 watts.
Updates: It featured a speech clipper to improve the punch and intelligibility of the AM signal.
Construction: The internal layout moved toward modular printed circuit boards, and it utilized an early linear integrated circuit (CA3053) in the IF stages.
Tuning: It retained the separate receiver VFO and crystal-controlled transmitter, requiring the "Spot" switch to align the two frequencies.
