HF-90 Operation & Installation Guide
If your HF-90 receives a Beacon Request, the response from
your radio is automatic - ie. there is no need for you to
respond manually. No Selcall Alarm will be received or
recorded when receiving a Beacon Request. If your HF-90
is in scan mode when you receive a Beacon Request, the
scan sequence will restart immediately, once the Beacon has
been transmitted.
Please note that, if you are using the HF-90 in conjunction with a
Q-MAC Electronics autotune system, you may hear a continuous
high pitched tone for a few seconds, having received a valid
Beacon Request, prior to the transmission of the Beacon. This
is the Automatic Tuner entering its tune sequence (refer to
Section 7.1 of this Guide).
Several seconds after pressing the STAR key to send the
Beacon Request, you will hear the Beacon as a series of
three or four tones (depending on which station you are
making contact with). The strength of these tones will
indicate whether or not you are on a suitable channel to
communicate with the other station. If the Beacon is very
weak, you should repeat the above procedure on another
channel. Once you have achieved a strong Beacon, you can
then proceed with your Selcall or Telcall to that station.
