Fairhaven RD500 User Manual - 4.13

select a new group unless you need to add to an existing one. A scan can now be made 

using the VFO frequency as a start point, or alternatively a band can be used, where 

the start and stop frequencies are specified. Up to 999 entries will be added to the 

current group, the records can then be renamed or deleted if not required. Entries of 

the same frequency will be made where signals have appeared many times, while this 

is useful to see the level of activity on a particular frequency the user may wish to 

delete this type of multiple entry after the scan. 

 Auto memory is selected by pressing - 

4. More,      2. Automem.    

Autotune. 

Auto tuning is enabled by selecting  4. More   and selecting   1. 

Auto tune.  

Autotune ensures that the signal is always properly tuned to, and the receiver will 

track drifting signals. The progress of autotuning is displayed on the tuning meter. 

(Autotune does not work with SSB modes).

 Frequency entry, fast tuning and fast stepping. 

The receiver’s keypad can be used for direct entry of frequencies unless a  menu, 

memory or band etc. has been selected. Any menu can be escaped from by pressing 

to get back to the normal tuning mode. When entering frequencies the 

first part of the entry will be in MHz, then the decimal point should be pressed and the 

remaining frequency can be entered. If the frequency is less than 1 MHz, it should be 

prefixed with 0.  For example  0.12345     

Fast stepping 

If  a decimal point is entered without prefixing it with a zero, the cursor will appear 

below the frequency display and the frequency can be incremented at the position of 

the cursor.  The cursor can be moved up and down to allow frequency steps from 10 

Hz to 10MHz. Enter returns to normal tuning mode. Alternatively, 

, (the step size facility) would be used for permanently setting the 

receiver to a conventional step size. 

Fast tuning 

Pressing  increases the manual tuning rates by a factor of 10, to allow a 

quick means of checking a large frequency range for signals. “F” is displayed at the
