[SBE] Hybrid issues.

[Curt Yengst]

Richard:
 
We have this identical setup at our emergency studio at our transmitter site.  (D-75 with Telos 1x6).  We had similar issues but got the level adjustments happy.

I just finished an install last week of a D75 with the SP-75 phone module and a Telos 1x6.  We used the "hybrid out" from the D75 to the Telos.  Everything works great in both live and recorded mode.  I had some problems when first tested with breaking across the hybrid but that was an issue of getting the level adjustment on the Telos correct.  They are very happy with this equipment.

	Not sure this is the issue. Although we don't use a profanity 
	delay (yet), we do delay our analog signal to match up with our HD 
	signal, which creates an on-air delay of about 8 seconds. This 
	feedback/echo is happening almost instantly (less than half a 
	second).

	"One jock claims it only happens on live calls, not on pre-recorded calls."
	
	Is it this simple:
	Are the problem callers not turning their radios off?
