Interfacing With Other Exciters - FlexRadio Systems Tuner Genius XL User Manual

6.3.2 Interfacing with Other Exciters

You can connect more than one radio type to a Tuner Genius XL, provided each radio is exclusively connected to
one of the tuner ports (A or B). Though each port has multiple interfaces to receive band data and key the
tuner, it does not support multiple radios on a single tuner port.
6.3.2.1 Elecraft
The tuner requires both band data and a PTT line from Elecraft radios. Band data is available using a custom
wired BCD band decoder cable.
PTT
Connect an appropriate cable (RCA male terminated on both ends) between the radio's Key output and the PTT
Input corresponding to the tuner Port used (A or B).
Band Data (BCD)
See the pinout diagram below for the cable configuration. The connection is the same for all Elecraft radio
models.
