FLEX-6700 - Software Configurations

From
Jump to: navigation, search

Over the Jan-Aug 2016 period many additions were added to the FLEX configurations.


The following was configured over the term:

  • N1MM
    • SO2R full duplex
    • N1MM can control two slices, on different bands
    • There were no measurements to determine if it would be dangerous to operate the FLEX over the two
  • WSPR
  • JT65 and JT9
  • RTTY
  • FLDIGI
  • Antenna Selection
  • Remote control (See VPN article)
  • Temperature monitor
  • SWR plotter

[edit] N1MM

First, these steps were followed: http://www.flexradio.com/downloads/using_n1mm_logger_with_smartsdr-pdf/

After N1MM could communicate with the Flex, RTTY was configured via the following steps.

[edit] WSPR

WSPR was configured via trial and error. The figure below shows the configuration that worked:

The TS-2000 is the serial CAT device that the Flext emulates. Interestingly, on WSJT-X, using the TS-2000 does not properly control the Flex, rather DX Labs Commander must be used in order for the rig to be controlled properly. Note how a second device for PTT is needed, on COM 8. This can be seen in the SmartSDR CAT configuration below:

[edit] JT65 / JT9

WSJT-X needs DX Labs Commander software in order to operate the FLEX. This is done using the configurations below in DX Labs:

The following settings are needed in WSJT-X

JTAlertX is used to monitor WSJT-X and alert the operator if a specific rule is met. For example, JTAlertX can monitor your logbook for new countries and play an audible alert if someone from that country is calling CQ. JTAlertX enables the operator to have WSJT-X running in the background while doing other work.

[edit] FLDIGI

FLDIGI radio control is enabled by loading a XML file available here: https://sourceforge.net/projects/fldigi/files/xmls/flex/

All slices on the Flex can be controlled by FLDIGI by loading the appropriate XML files. The XML files are then loaded into FLDIGI and the following configurations are made as seen in the figures below:

[edit] Future Work

The Flex needs its full duplex characteristics to be measured. We don't know if the front end of the Flex will be overloaded using our antennas and reflecting against buildings like ECS or the various metal structures on the science buildings. Future work with Additional characteristics need to be measured how the K3 affects the Flex if both have selected antennas at the sametime. For example, if the K3 was transmitting on a 20m yagi and the flex was on a 6m yagi, what level of attenuation exists? If there is a danger to the flex, the Array solutions 6 pack can be retrofitted to disconnect the Flex antenna when the K3 has selected an antenna. Further measurements are needed to determine how the flex handles running continuously at various power levels. The new 4o3a flex amplifier requires a drive level of 50W, which needs to be monitored for continuous duty cycle modes like RTTY and PSK31.
