Ok, I am having a brain fart here....
Will a standalone quantar repeat a secure signal without a DIU?
For instance, is I just put one up on a mountain top somewhere as a basic astro repeater...and I flip on xxx-xl, will it pass?

Quantar secure question
Lowband radio. The original and non-complicated wide area interoperable communications system
..
if it is programmed to do so, yes it will.
quantars can only be transparent w/o a diu... but the good deal is that no additional hardware is required inside the station.
be advised....
XL operation and IMBE operation are *NOT* intermixable... you can have the following combos:
analog only
analog and securenet
analog and IMBE
IMBE
you can run secure IMBE (the quantar doesn't care if it's encrypted - it's all digital)
but
you can't run analog -xl on a machine set up for mixed mode analog/IMBE
also, if you program a station with Quantar v13.xxx RSS, you will remove all securenet functionality from the station... this is documented in the help file as securenet analog encryption is "no longer supported"

Keep in mind that there is no DVSI IMBE codec in the Quantar station, so while it can pass IMBE, it can NOT encode nor decode it. The DIU3000 is essentially a box with a DVSI vocoder in it, plus a bunch of other things (e.g., encryption module, optional ASTRO modem or V.32 signaling, interface to standard analog remotes, etc.). The DIU3000's primary attribute is the coveted IMBE chip, of course.
Motorola left the DVSI IMBE vocoder out of the Quantar for two main reasons: 1) the Quantar BOM list had gotten very, very high, and they couldn't "afford" to put any more upward pressures on the cost of the DIU's BOM, and 2) for any type of "decent" secure operations, the decrypting/encrypting functions must take place remotely from the Quantar site, such as very nearby or optimally physically collocated at the customer end point loactions. Therefore, the encrypted digital audio should ride down the dedicated circuits in encrypted form. This necessitates that the vocoder and encryption process be remote, thus the DIU.
The Quantar replacement also has its vocoder remotely in a DIU-like box, albeit it is somewhat smaller since the ASTRO modem function (and others) are accomplished in DSP, as opposed to discrete option boards, such as what is used in the DIU3000. And, Yes, the DIU3000 with its ASTRO modem board thankfully will be fully compatable with the Quant replacement.
