<h3>1: Frequency shift from center frequency of reception</h3>
Use the wheels to adjust the frequency shift in Hz from the center frequency of reception. Left click on a digit sets the cursor position at this digit. Right click on a digit sets all digits on the right to zero. This effectively floors value at the digit position. Wheels are moved with the mousewheel while pointing at the wheel or by selecting the wheel with the left mouse click and using the keyboard arrows. Pressing shift simultaneously moves digit by 5 and pressing control moves it by 2.
<h3>2: Channel power</h3>
Average total power in dB relative to a +/- 1.0 amplitude signal received in the pass band.
<h3>3: Level meter in dB</h3>
- top bar (green): average value
- bottom bar (blue green): instantaneous peak value
- tip vertical bar (bright green): peak hold value
<h3>4: BW - RF Bandwidth</h3>
This specifies the bandwidth of a LPF that is applied to the input signal to limit the RF bandwidth.
<h3>5: Dev - Frequency deviation</h3>
Adjusts the expected frequency deviation in 0.1 kHz steps from 1 to 6 kHz. POCSAG uses FSK with a +/- 4.5 kHz shift.
Check to filter (discard) duplicate messages. Right click to show the Duplicate Filter options dialog:
- Match message only: When unchecked, compare address and message. When checked, compare only message, ignoring the address.
- Match last message only: When unchecked the message is compared against all messages in the table. When checked, the message is compared against the last received message only.
When clicked, opens the Notifications Dialog, which allows speech notifications or programs/scripts to be run when messages matching user-defined rules are received.
By running a program such as [cmail](https://www.inveigle.net/cmail/download) on Windows or sendmail on Linux, e-mail notifications can be sent containing the received message.
By checking Plot on Map, if a message contains a position specified as latitude and longitude, the message can be displayed on the [Map](../../feature/map/readme.md) feature.
The format of the coordinates should follow [ISO 6709](https://en.wikipedia.org/wiki/ISO_6709), E.g: 50°40′46″N 95°48′26″W or -23.342,5.234
* Address - The 21-bit pager address the message is for.
* Message - The decoded message, as per Decode setting (8). This will be empty for "tone only" messages (i.e. when the pager beeps without a message).
* Function - Function bits. In some instances this is used to specify the encoding of the message (Numeric/alphanumeric). In others, it is the pager source address.
* Alpha - Message decoded as alphanumeric text, regardless of Decode setting (8)
* Numeric - Message decoded as numeric, regardless of Decode setting (8).
* Even PE - Number of even parity errors detected in the code words of the message.
* BCH PE - Number of uncorrectable BCH parity errors detected in the code words of the message.
Right clicking on the table header allows you to select which columns to show. The columns can be reordered by left clicking and dragging the column header. Right clicking on an item in the table allows you to copy the value to the clipboard.
