I have just wired up my 524 set and ran the cable (cx-4723) to my intercom box (C-229) and from this i have connected a LS 454U loud speaker and a handset H-250/U.
My problem is i cannot hear myself transmit in the front loudspeaker or in the earpiece of the handset at all, the volume is up and the set does power up when the front handset is keyed.
When at the radio itself i can hear my transmissions in the set speaker and through the earpiece of the headset H251.
Im also experiencing a sound like a helicopter in my ear when the set transmits???.
I have swapped handsets and know that all my audio kit is good, any advice would be great.
