[NHRC-user] NHRC-4/M2 Question

Sun Mar 3 17:37:16 EST 2002

Hi David,

   IT would require more than the TS-32 to give you a valid input on the 
NHRC-4.  If you are hooked up with the CTCSS-required scenario, you will 
need CAS(COR) and CTCSS to indicate valid signal to the NHRC-4.

   If you would like, we can check out your controller for you.  Give us a 
call and we can arrange this.

   Regards,

   Jeff Otterson
