ETH085 – JT Modes with Ria Jairam, N2RJ

ETH085 - JT Modes
Share

In this episode, I have the privilege of talking with Rai Jariam, N2RJ, for a third time. This time we are talking about the JT Modes, JT65, JT9 and the newest addition FT8.

Here is a typical conversation over JT65:

“CQ K5CLM EM12” CQ call from K5CLM with his locator
“K5CLM N2RJ FN21” N2RJ replies to K5CLM with her locator
“N2RJ K5CLM -12” K5CLM sends his signal report
“K5CLM N2RJ R-08” N2RJ replies with her signal report
“N2RJ K5CLM RRR” K5CLM says Reception Report Received (all OK)
“K5CLM N2RJ 73” N2RJ says Best regards
“N2RJ K5CLM 73” K5CLM says Best regards

Each message of up to 13 characters is sent over the course of 50 seconds, starting at the top of each minute, so the above conversation would take seven minutes. One person sends on the odd minute, and the second person sends on the even minute.

The JT modes are not for rag chewing or typical conversations, they are for chasing contacts and that’s about it. They are not designs to make contacts to talk to, but just to exchange the above information. Call sign, Grid Square and Signal Report.

PWRCheck Power Monitor from West Mountain Radio - JT

Do you have an old fashioned Analog Volt and Amp meter hooked to your station? Are you looking to find something that has more bells and whistles? Check out the West Mountain Radio PWRcheck.

The PWRcheck has eight display modes including voltage, current flow in either directions, wattage and amp-hours and will measure from 0-60V with 40A continuous load. It is accurate to within +/- 10mV and +/-10mA.

It has a backlit graphics LCD that will display data in digital, analog and bar graph formats. You can even monitor your backup battery with a programmable “gas gauge”.

The non-volatile memory stores more than 100,000 data points without power. That is nearly two and a half months worth of data @ 1 point per minute!

It has a USB computer interface for configuration and data download and you can program it to sound an alarm for over current, over or under voltage and amp-hours.

The software that comes with it allows your to program every aspect of the PWRcheck operation such as data logging rate, display formats and alarm conditions. You can display current, voltage, wattage and amp-hours in real time. It has integrated charting software that automatically collects and displays data. All the data can bed downloaded and stored for later analysis!

    Ria neglected to mention that WSJT-X is compatible with Windows, macOS, and Linux operating systems. You just need to make sure you download the correct version for your OS.

    Also, JT-Alert is Windows only. For macOS there is JT-Bridge (http://jt-bridge.eller.nu) . JT-Bridge acts as a bridge between WSJT-X and most common logging applications for the Mac.

    From the website:

    • Displays CQs from WSJT-X
    • Double-click on a CQ to reply in WSJT-X
    • Check QSO and QSL status of calls, DXCC entities, CQ zone, ITU zone, State, IOTA, Grid and Continent in your logging application
    • Send logged QSOs from WSJT-X to your logging application
    • Support for Aether, MacLoggerDX and RUMlogNG logging applications
    • Send notifications to OS X Notification Center for unworked or unconfirmed items.
    • Send a notification to OS X Notification Center when you are called
    • Read transceiver frequency from your logging application
    • Set transceiver frequency via MacLoggerDX or RUMlogNG
    • Control the PTT via your logging application
    • QRZ or HamQTH call book lookup
    • Show LoTW and eQSL users
    • Show distance and bearing to CQ caller
    • Show information about the station worked with WSJT-X
    • Macro buttons with information about the station being worked
    • Mark CQs with strikethroughed text, if the CQ specifies a call area that you are not within.

    • Yes I totally forgot about that BUT I did mention that it is open source so you can pretty much compile it for anything you desire. I also did not know about JT-bridge. I’ll try that on my Mac next time. Thank you.

    • You’re welcome. JT-Bridge is a great app!

      Some hams aren’t good at some computer stuff, like compiling programs. I’m just glad they have the DMG/.app for the Mac.
