Two cable connections are required from the SignaLink to the
Elecraft KX3 as follows:
Connect the RJ-45 end of the SLCABKX3 radio cable to
the SignaLink’s “Radio” connector. Connect the 4-pin
right-angle
TRRS plug to the KX3’s “Mic” jack, being
sure to fully insert the plug.
Connect the supplied
right-angle
mono audio cable
between the SignaLink’s “SPKR” jack, and the KX3’s
“Phones” jack. Be sure that both plugs are fully inserted.
KX3 Radio Settings:
1 - The “Mic Bias” setting in the KX3’s menu system should be
turned OFF if you are using jumper wires. This setting can be
left ON if you are using our SLMODKX3 jumper module as it
has a built-in DC blocking capacitor.
2 - The “Mic Btn” setting should be set to either “PTT”, or
“PTT Up.Dn.”.
3 - We recommend turning the KX3’s “Audio Effects” feature
OFF, as it will likely cause receive problems during digital
operation.
