U20282 Used Elecraft SP4 External Speaker

U20282 Used Elecraft SP4 External Speaker

Overall Condition: Used, very good functional and cosmetic condition! Shows light surface scuffs on the outer black case from normal shack use, but overall well-kept. Front mesh grill, front panel labeling, rear input/output jacks, bottom rubber feet, and flip-down tilt bail are all clean and intact.

Designed to match the styling and high performance of Elecraft's K4, K3S, and K3 transceivers, the Elecraft SP4 is a high-efficiency external speaker engineered specifically for speech clarity and weak-signal HF operating.

The SP4 features a front-panel A/B input selector switch, allowing you to quickly toggle between two separate audio sources (such as dual receivers or two distinct transceivers). With a rear expansion output jack for chaining a second SP4 speaker, it easily supports true stereo reception, dual-watch, or main/sub-receiver audio separation setups.
