Prior to its launch, CBC Radio programming aired on private affiliate CHNS and its shortwave relay CHNX 6.13 MHz (in the 49m band).

However, CBH had to conform its nighttime signal to protect clear-channel sister station CJBC in Toronto, rendering it practically unlistenable at night in some parts of Halifax.

The station's local programs are Information Morning and Main Street, hosted by Jeff Douglas, in the afternoon.

The station serves the Nova Scotia mainland through a network of rebroadcast transmitters, whose schedule is identical to the signal out of Halifax, with the exception of a regional program weekday afternoons from 3:00 to 4:00.

On December 10, 2018, the Canadian Radio-television and Telecommunications Commission (CRTC) approved the CBC's application to operate a new FM transmitter in Digby at 107.1 MHz (channel 296A) with an effective radiated power of 420 watts (non-directional antenna with an effective height of antenna above average terrain of 256.6 metres).
