I picked up one of those OLD Lucent digital phone answering machines at the local thrift store for $2.00.  Connected the speaker output directly to the phone patch input on my SB-101.
 
I recorded a "CQ" on the out-going announcement.
 
BTW, I left a 5 sceond pause at the end of the CQ message so that I would have time to un-key the mike after "calling CQ" and before the "Beep".
 
IT WORKS !!!!.  Admittedly the impedance match causes a loss of audio quality but that will soon be solved with an audio transformer.
 
I did put a $1.99 switch in the circuit to the phone patch output and an RCA jack on the back of the device.
 
TOTAL COST so far is about $4.50.
 
 
Comments welcome!!!
