Q-MAC Electronics Pty Ltd HF90 Manuale Utente

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.
