Comrex and ISDN Services

KGNU provides studio services to the broadcast industry for Comrex, ISDN, and tape sync interviews. We use Comrex ACCESS and Telos Xstream ISDN, each accessible from 3 studios.

Rates, scheduling

We charge $150 per hour, with a one hour minimum, and in 15 minute increments thereafter. Call Operations Director Evan Perkins at +303-449-4885 or email us for connection details and to schedule a time.

Please note that once you have booked a studio with us, it means that we have reserved time in our schedule exclusively for you. If you cancel your booking less than 24 hours before it is scheduled to take place, you will be subject to a cancellation fee of $100.

To avoid a cancellation fee, please notify us at least 24 hours prior to your appointment. You can cancel or reschedule an appointment by emailing us or calling our office at +303-449-4885.
