Disable router queries – When this box checked, Router will not poll the radio for frequency and mode when
that information is not available from the communication between the application and radio.
NOTE: "Disable router queries" disables Router polling only when the port has been opened by an
application program. When the virtual port is closed, Router always polls the radio to support the
automatic switching and iLink update functions. If it is necessary to disable all polling, select one
of the "none" options in the Radio box.
WARNING: DO NOT select "Disable Router queries" unless you have a specific reason to do so. Router only
polls for information that is not requested by the logger and does not interfere with logger polling. Disabling
Router queries may result in incorrect frequency and/or mode decoding and can have a serious impact on
overall operation.
PW1 on radio bus – When this box checked, Router periodically generates an Icom "Transceive"
broadcast to keep the PW1 synchronized.
NOTE: Check this box if you have an IC-PW1 or other Icom compatible accessory physically
connected (in parallel with the transceiver). Do not check this box if the only connection is to the
transceiver and the PW1 or other other accessory is connected to the accessory CI-V PA port
(described later).
Forward autoinformation to CAT port: When checked, all unsolicited packets (Icom "transceive" packets
or "Auto-information" data from Kenwood, Elecraft and recent Yaesu transceivers), coming from the radio
are transfered to the CAT port. Each CAT port has own check box.
Port: Defines a virtual or hardware serial port for an SDR radio used with the MK2R. The CAT connection
in MK2R is disabled. This function is not currently supported.
SDR Tracking:
Tracking: This function allows an external receiver to track the transceiver attached to the MK2R.
NOTE: The transceiver attached to MK2R must be properly interfaced and CAT must be
functioning properly. Tracking does not work for "no radio" choices.
Radio: Specifies SDR receiver model.
Source QRG: Specifies whether the SDR will track the transceiver transmit or receive frequency. .
Port: Specifies COM port used to communicate with the SDR.
Offset: Frequency offset between the receiver and transceiver. Default is 0Hz, resolution is 1Hz.
NOTE: For specific SDR receiver configurations, please refer to Appendix . .
The bottom two-thirds of the Radio window is a serial communication monitor. The monitor uses colors and tags
to indicate which device is responsible for the data. Black queries (H1-TX or H2-TX) and gray radio responses
(H1-RX or H2-TX) are from the "host" application (e.g., logger), H1 indicates the host application on the main
CAT port, H2 is the host application on the 2
from/to Router and not routed to the application.
Router monitors the communication when the host application performs control and polls the radio periodically
for any missing information (VFO frequencies and mode). Because some applications do not poll the radio
regularly or completely, Router must break this communication to update its internal state. In order to avoid
confusing the application when Router polls the radio, data from the application is buffered and sent to the radio
after Router receives a response to its query. If Router does not receive response to a poll within the time
allowed or does not understand the response, it displays "oldest query discarded" but forwards all data to the
virtual serial port to avoid confusing the application (logger).
