Listing memory channels:
The first channel listed (in blue on colour monitors) is the memory channel that will appear on the
display of the TFM-138B when it is turned on. The next two channels listed are guard 1 and guard
2. (in red on colour monitors) Only TX CTCSS tones or TX DPL codes are listed for the guards
since the TFM-138B has a CTCSS tone/DPL code decoder for the main receiver only. The rest of
the memory channels displayed (in yellow) are the 120 memories listed in sequence. Either
LOCK or SCAN is displayed for each memory channel which indicates whether that memory
channel will be included in the scan list or locked out. After reviewing the multi-page list, you have
the option to return to the final page, for further review, to return to the main menu or to print out
the memory channel list.
Edit menu:
You can select which memory channel to program, main or guard. When entering memory
channel information, if you just press return, the previous information will be retained. For
example, you only want to change the receive frequency. Type in the new receive frequency and
press return for all of the other prompts. You also will not be able to type in frequencies or
information that does not make sense. If the information entered is not what was prompted for,
you will be re-prompted for the correct information. For example, if you type in 999.9999 for the
transmit frequency you will be prompted again because the frequency range of the TFM-138B is
138 to 174 MHz. Keep in mind that the label for the memory channel can only have characters
that exist on the TFM-138B. These include only capital letters, numbers 0 to 9 and a few other
characters. Any other character will show up as a blank on the unit’s display.
You will then be prompted to enter a receive CTCSS tone, a transmit CTCSS tone, a receive DPL
code and a transmit DPL code. Although both CTCSS tones and DPL codes can be programmed
simultaneously, this should not be done. Care should also be taken to program the correct DPL
code since non-unique (inverted) code numbers will be accepted.
Downloading to the Transceiver:
Select 'D' from the main menu. Follow on screen instructions. The memory channels will be
downloaded sequentially to the TFM-138B. You will be able to see them on the radio's display as
they go by. The download process will take several minutes. (The data transfer is fast but the
non-volatile memory in the radio needs time to program.) The PC will return to the main menu
when the process is complete. The radio will also return to the normal operating mode when
done.
Files:
The file containing the memory channel list is named 'DATA1' in the \PCDLB directory. The
program will not run if it can not find the 'DATA1' file. To have multiple databases, you can copy
the data file to a new name and edit the 'DATA1' file again. To retrieve a database, copy it back to
'DATA1'.
