16 Quickstart for common use cases
This chapter is rather intended for those users, new to HAM-radio. If you are
familiar with analog ham-radio but new to DMR, we suggest to take a closer look
at the document we did prepare some time ago (not specific for the DB25-D or
GD88 but most topics applicable for the Radiod
d ity DB25-D and GD-88as well. You
find the document via our Blog entry at:

The next subchapters describe the most common use cases for the Radiod d ity
DB25-D and GD-88. Only those CPS menus that are mandatory for the specific
operation mode will be covered in the explanations.
If you do not understand all specified parameters that are mandatory for a certain
use case, we advise you to read the corresponding paragraphs of this manual. Yes,
the manual is quite comprehensive, but it is intended to make it easier for you to
get the best results out of your
Radiod d ity DB25-D and Radiod d ity GD-88.
16.1 Simplex analog FM operation with other station
In order to setup the radio for simplex analog FM operation, follow these steps:
1. Add a new zone via ‘ Zone[Channel] ’
→
‘ +Add ’ and give it a ‘ Zone Name ’ of
‘ simplex FM ’ . The new zone will be created and will already contain a channel of
either ‘ CH mode ’ being ‘ analog ’ or ‘ digital ’ .
2. Setup the channel for ‘ CH mode ’ being ‘ Analog ’ .
3. Give the channel a ‘ CH Name ’ of some name, e.g., ‘ FM simplex ’ .
4. Set both frequencies ‘ RX Freq ’ and ‘ TX Freq ’ to the very same value (e.g., 145.500
MHz or 432.100 MHz). You may choose any frequency that is allowed for your
type of ham radio license, for analog FM operation and not occupied by some
other station. Make sure the other station you want to call is setup for the very
same simplex frequency.
Notes: Do not use GMRS-frequencies or other frequencies that are not allowed to
be used for analog FM with an output power of more than allowed for the
specific frequency band.
5. Set the output ‘ Power ’ to ‘ Low ’ if the other station is close to yours. If the other
station is some miles away, you may need to set it to ‘ High ’ .
6. Set ‘ Scan List ’ to ‘ off ’ in order to avoid unexpected behavior.
7. Set Bandwidth to either ‘ 12.5 ’ or ‘ 25 ’ (kHz), depending on your personal
requirements. If unsure on that one, set it for ‘ 12.5 ’ (kHz).
