Operating FT8 Remote on the 6m Band

FT8 Digital Remote Setup

FT8 Digital Remote Setup

I have been operating using the FT8 digital mode on the 6m band using our remote operating gateway quite a bit this summer. The SDR-based remote operating gateway in our station allows us to operate our station from other rooms in our home as well as from outside our QTH via the Internet. When I’m at home, I have computers set up with outboard monitors to create an operating setup for FT8 digital contacts on the 6m and other bands. The photo above shows this setup. Having the extra screen space and multiple laptops enables control of our station, making and logging QSOs, and checking propagation via Reverse Beacon Networks as we operate.

Radio and Logging System

The main system is a windows laptop. It runs the SmartSDR software which operates the Flex-6700 Radio in our shack (upper right window below).

This laptop runs the WSJT-X software (left windows above) which conducts QSOs in FT8 and other weak signal modes and the JTAlert Software (lower right windows above) which interfaces WSJT-X to the DXLab logging suite. JTAlert displays all callsigns decoded by WSJT-X and compares them to my log to determine which potential contacts are new DXCC’s, Grids, States, etc. JTAlert adds contacts to my logs in DXLab when a QSO is completed using WSJT-X.

The windows laptop also runs the DXLab logging suite. DXLab handles logging of QSOs, one-click pointing of our antennas based upon the callsign being worked, and uploading contacts to LoTW, eQSL, and ClubLog for confirming contacts.

I like to use the second computer to monitor propagation and strength of my FT8 signal while operating.

I use two tools to assess propagation conditions while I am operating. The first is PSKReporter which is a Reverse Beacon Network (RBN) tool that is enabled by WSJT-X and most other digital mode software programs. Each time WSJT-X decodes a stations transmission, it reports the decoded callsign along with location and signal strength information to the PSKReporter website. This website then uses this information to display all of the stations that hear my and other’s transmissions in real-time. The RBN information is used to determine where a given band is open and as a tool to determine how much transmit power is needed to provide acceptable signal strength at stations that I am trying to work.

The DXMaps website shows a real-time map view of contacts being made on the 10m and higher bands. This second tool provides a real-time view of band conditions and opening on bands like 6m which have somewhat unpredictable propagation characteristics.

Together, these tools help to determine where to point antennas and what stations we can work on the 6m band.

The second laptop also runs Teamviewer remote control software. This provides access to the antenna switching controls, SWR and power monitoring equipment, station electrical power, and amplifier controls in our shack. These tools are important elements in safely operating and controlling our station when we are not in the same room as the radios and other equipment we are using.

I’ve been using the remote operating setup described here on the 6m band quite a bit over the last few weeks. I hope this post provides some ideas that other can use.
