Introduction
The DaySequerra M3 HD RadioTM Multi-Tuner is the first broadcast quality monitor available with three
AM/FM tuners each complete with multicast capability. The M3 has been designed as the benchmark
in sensitivity (< 15.0dBf in FM) and reliability, and at the same time delivers the highest quality,
accurate monitoring of existing analog and HD RadioTM AM and FM broadcast signals (THD+N <.005%
with stereo separation >90dB for HD RadioTM FM signals).
Each of the three independent tuners in the DaySequerra M3 features an ultra low noise RF front-end
with built-in preselector and double-balanced mixer, low-jitter DAC and Class-A biased audio outputs
provide the highest fidelity reception and demodulation of HD RadioTM programs, including display of
program applicable data (PAD) for MPS and multicast signals, including Apple “Buy Button” UFID.
Its robust, modular architecture ensures that the M3 will never become obsolete. The rugged M3
chassis houses dedicated hardware RF, audio and power supply modules that, along with firmware
updates via flash programmable memory, completely anticipates the growth of new HD RadioTM
services and programming. This design approach along with our product update program ensures that
a broadcaster’s investment in a DaySequerra product will continue to pay off well into the future.
Please read this manual thoroughly before operating your M3.

HD RadioTM PAD message data field for approximately 5 seconds before scrolling to the next PAD data
field.
The PAD UFID (unique file identifier) contains a hierarchal encoding of “Buy Button” or song purchase
information. Each UFID frame consists of two components: an owner identifier in the form of a URL
(uniform resources locator) and an ID (purchase identifier). The URL will be displayed as an internet
URL, e.g., www.itunes.com. The ID component contains the purchase identifier according to the
specific encoding format defined for that owner.
Station long name, station short name and program type are processed as an ID3 tag. HD RadioTM
PSD message, i.e., song title, artist, album, genre, comment, commercial and UFID “Buy Button” fields
are limited to 127 bytes each for a total of 1018 bytes per message per iBiquity specifications. For
more information on ID3 tags and PSD messages, please visit www.ibiquity.com and www.id3.org.
When an HD RadioTM FM broadcast is forced to analog using the Forced Analog option in the
FORCING menu, the default DATA - DISPLAY setting is off with the RBDS program information field,
most often the station short name, to be displayed in second line of VFD. Each subsequent momentary
push of SELECT switch scrolls through each RBDS field in the following sequence:
•Program Type (PT)
•Program Identification (PI)
•Radio Text (RT)
Subsequent momentary push of DATA - DISPLAY switch turns DATA - DISPLAY mode and DATA -
DISPLAY LED off. VFD display second line scrolls if RBDS field is longer than 16 characters. If there
is no data for the selected field, VFD displays “NO” plus the data category, e.g., “NO RT DATA.”
If “Scroll All Data” mode is enabled in DATA - DISPLAY menu, as described above, tuner displays each
RBDS data field for approximately 5 seconds before scrolling to the next RBDS data field.
