An enhanced Memory form that incorporates new features and supports the new
FM
Repeater mode of operation is available with
PowerSDR
v2.1.5. The new Memory form (or window) is designed primarily for
FM
mode, but can be used with any mode. A representative screen shot of a populated Memory form is shown below.

As you see, each memory form record consists of different data fields. The table below describes each memory channel field in the memory channel entry.
Memory Form Field Description
Group
This is a "free form" field that you can categorize memories based on user defined group name
RX
Frequency
This is the
receiver
frequency for
VFO
-A
Name
This is the name of the memory that is displayed in the Channel drop down box on the console when in
FM
mode
DSP
Mode
This defines the Mode of operation for the memory entry. All
PowerSDR
modes are valid and selectable using the drop down box
Tune Step
This defines the Tune Step value for the memory entry. All
PowerSDR
Tune Step values are valid and selectable using the
drop down box
RPTR (Repeater mode)
This determines
if
the radio is operating in
simplex
or Repeater mode. High, Low and
Simplex
values are valid and selectable
using the drop down box
RPTR Offset
This defines the Repeater offset frequency in
MHz
.
Valid only in
FM
mode
CTCSS
This check box determines
if
a
CTCSS
tone is added when transmitting.
Valid only in
FM
mode
CTCSS
Freq
This defines the
CTCSS
frequency or sub-audible tone in Hz transmitted.
Valid only in
FM
mode
Deviation
This determines the transmit frequency deviation selectable using the drop down box.
Valid only in
FM
mode
Power
This determines the transmit power in watts. Valid values are 0-100
Split
This determines
if
the radio is in
SPLIT
mode.
If
this option is selected, the radio is automatically taken out of Repeater mode and
put into
SIMPLEX
mode. Refer to the KB article
How to Use
FM
Repeater Mode
for additional information.
TX
Frequency
This defines the transmit frequency. It is a user defined value that is valid only in the
simplex
mode of operation.
The default value is the
RX
frequency unless you are copying data from
VFO
-A to memory when the radio is in
Split
mode and the
TX
frequency is different than the
RX
frequency
RX
Filter
This determines the defined
RX
filter
specific for the
DSP
mode.
NONE is the only valid option for
FM
mode
RX
Filter
Low
This displays the
RX
filter
low cut point. It does not define the
RX
filter
low cut value in
FM
mode
RX
Filter
High
This displays the
RX
filter
high cut point. It does not define the
RX
filter
high cut value in
FM
mode
Comments
This is a "free form" field that you can add comments specific to the memory channel
AGC
Mode
This defines the
AGC
setting. The
AGC
setting is selectable using the drop down box
AGC
-T
This determines the
AGC
Threshold for the memory channel. Valid values are 0-100
Getting Started with Using Memory Channels
To open the Memory form, select
Memory
from the
PowerSDR
menu bar.
There are several operations that can be performed to add, delete, manage and select a memory (or memory channel). The following sections will describe these operations in greater detail.
How to Add a Memory Channel
Adding a memory channel to the Memory database is easy. It will take the currently configured parameters on the
PowerSDR
console and store them as a memory channel "record" that can be recalled later.
Open the Memory Form from the
PowerSDR
menu bar by
left clicking
on it
Left click
on the
ADD
button at the bottom of the Memory form
A new memory channel will be added to the memory form at the bottom.
At this point you can customize or change values in the new memory channel. Changes you make to the memory channel record are automatically saved to the database so there is no need to do anything to save the changes

How to Select a memory Channel form the Memory Channel Form
Once you have created a memory channel using the ADD feature, you can recall or Select the memory channel which is change the
PowerSDR
operating mode to the parameters defined in the memory channel. There are two ways to select a memory channel from the Memory database. You can select the memory channel directly from the Memory form or you can select the memory channel from the
PowerSDR
console when operating in
FM
mode. This example selects the memory channel from the Memory form.
Open the Memory Form from the
PowerSDR
menu bar by
left clicking
on it
Left click
on the
SELECT
button at the bottom of the Memory form
The information in the memory channel will be transferred to the
PowerSDR
console

How to Select a Memory Channel from the
PowerSDR
Console
As noted above, there are two ways to select a memory channel. The following example demonstrates the second way of selecting a memory channel by using the option in the
PowerSDR
console when operating in
FM
mode.
From the
PowerSDR
console, select the
FM
mode
In the
FM
mode specific control area on the console
left click
on the
Channel
drop down box
A listing of all memory channels will be displayed (see screenshot below).
Left click on the memory of your choice. In the example below the
SkyWarn
memory channel is being selected.
The information in the memory channel will be transferred to the
PowerSDR
console

How to Copy a Memory Channel
If
you want to make a copy of an existing memory channel to use as a starting point or template for creating a new memory channel, you do this by executing the following procedure.
Open the Memory Form from the
PowerSDR
menu bar by
left clicking
on it
Using your mouse,
left click
on the far
left hand side
of the memory channel you want to use as the source information. The memory record will highlight and there will be a right pointing triangle in the far left hand side indicating that the memory channel has been selected.
Left click
on the
COPY
button at the bottom of the Memory form
A new memory channel will be added to the memory form at the bottom.
At this point you can change values in the new memory channel to create a new unique memory channel.
Changes you make to the memory channel record are automatically saved to the database so there is no need to do anything to save the changes.
How to Sort Memory Channels
You can change the sort order of the memory channels by simply clicking on the column header.
Left clicking
on the memory column
header
once will display a small upward pointing triangle indicating that the column is sorted in ascending order from top to bottom.
Left clicking
on the column
header
again
will display a small downward pointing triangle indicating that the column is sorted in descending order from top to bottom.
How to Delete a Memory Channel
You can delete unwanted or un-needed memory channels by using the Delete feature in the Memory form.
Open the Memory Form from the
PowerSDR
menu bar by
left clicking
on it
Using your mouse,
left click
on the far
left hand side
of the memory channel you want to delete. The memory record will highlight and there will be a right pointing triangle in the far left hand side indicating that the memory channel has been selected.
Left click
on the
DELETE
button at the bottom of the Memory form
A confirmation dialog box will appear asking you "Are you sure you want to remove the selected row(s)?".
Left click
on
YES
to delete or
NO
to abort this operation
If
you clicked
YES
, the memory channel was removed from the Memory database.
Modifying Data in a Memory Channel
Once you have a memory channel defined, you can change any of the data fields on the memory channel record. Note that
if
you change the value of one field, that it does not necessarily update other fields in the memory channel record. As an example,
if
you change from
Simplex
to Repeater mode with a positive 0.600
MHz
offset, the
TX
Frequency is not updated to reflect a
TX
frequency that is 0.600
MHz
greater than the
RX
Frequency.
