And that's why we offer the KPAK3AUX cable set, which includes: 1. The AUX cable between the K3 and KPA500 with several pins removed (see cable description in the KPA500 manual). 2. A Y cable to allow more than one device to use the K3s AUX connector when th eKPAK#AUX cable is in use. 3. A M-F 15 pin adapter with the PTT pin removed to allow other devices to interrupt PTT via the regular RCA-RCA PTT path, if needed.
