<br></div>Using compression on the refteks helps alot, so use either CO or C2, but be aware that C2 for a very quiet station can pack more samples into a reftek packet than will fit into a tracebuf, resulting in the tracebuf being booted out of the system. For most normal stations this shouldn't be an issue, and in the cases where it is you can use CO or can set the gain to x32, or both.<br>

Our real-world numbers from 6-channel Q330s (Steim 2
compression) show volumes of about 3.2Gb/mo or less. We have
exceeded the 5Gb/mo limit when there is some pathology at the
station that causes lots of resends. So far our carrier, Verizon,
has not dinged us for any overages.<br>
