Sigtronics SPA-400 Panel-Mount Intercom
TSO'd four-place panel-mount intercom, made in the USA.

Integrated area navigation unit with VOR/LOC, glideslope and DME.
The KNS-80 combined VOR/LOC, glideslope, DME and RNAV in a single box, letting a pilot build waypoints by radial and distance long before GPS arrived. Still a practical way to keep an older IFR panel capable on DME and add area navigation without a full stack rebuild. Offered used; we confirm tray, connector and indicator compatibility with your aircraft first.
