====================================================================== From a discussion with OM Curt Kolovson (W6RQ), who wants to use his » TG-5-B « as a MORSE-TRAINER, we came to the following SOLUTION ... ====================================================================== o No [BA-2] Line-Battery o No [2BA-30] Local 2 x 1.5 Volt Batteries ... ... INSTEAD: Connect ( on front ) Ports (+) & (-3) with a 6 Volt (= 4x1.5 ) PACKAGE or a 9 Volt BLOCK o CONNECT PORTS (L2) === (-3) o Hit the MORSE-KEY ........... and set RECEIVER-RELAY appropriate ... until the B E E E P s are clear and separated COMPARE THE WIRE-DIAGRAM: ----------------------------------------------------------------------- This configuration let the MORSE-KEY be in loop with the RECEIVER-RELAY and 6 ( or 9 ) VOLT PACKAGE. When the MORSE-KEY is hit, the CONTACTS of the RECEIVER-RELAY are activated and the BELL chimes ( or a "BEEEP" can be heared in the connected HEADPHONES instead ). R E M A R K S T O M A I N T E N A N C E I F N E C E S S A R Y : ----------------------------------------------------------------------- o Clean CONTACTS of RECEIVER-RELAY with a strip of fine sandpaper o Wiggle CENTRAL CONTACT: Its position is critical !!!
