WSJT-X
WSJT-X is a computer program developed by Joe Taylor – K1JT that is used for weak signal radio communication modes like FT-8. The software is well documented and widely used by amateur radio operators.
In addition to numerous YouTube videos, the three URL’s listed below should provide a comprehensive reference on which to start learning about FT-8 and weak signal communications.
JT Alert
JT Alert is a companion program for WSJT-X. If you use WSJT-X for FT4 or FT8 you will love JTAlert. JTAlert will allow you to set up audio and visual flags for wanted grid squares, states, countries, provinces etc. When these entities are seen as an incoming CQ they will be highlighted in selected colors for you to decide whether you want to try to initiate a QSO. Another great feature allows you to open a text box to communicate directly with an FT4 or FT8 contact, like text messaging by radio, if they have this function enabled on their end. Another great feature is the flagging of incoming CQ’s with “B4” if you have already had a QSO with that callsign on the band being used. JT Alert is a very sophisticated WSJT-X add on that you are sure to love.

QRZ
QRZ is one of the most popular amateur radio apps. It allows a lookup for callsigns, QSO on-line logging capabilities, QSO confirmation, awards for various types of confirmed QSO’s, biographies, and much more. It must also be noted that QRZ requires an annual subscription. The annual subscription currently costs $35.95
Here is a sample QRZ logbook:
ARRL – LOTW
Logbook of the World (LOTW)
Logbook of the world is arguably the most widely used on-line logbook in the world. The vast majority of your QSO’s can be confirmed on-line thru LOTW. There is no charge for using LOTW for logging, however there will be a charge for securing award certification and certificates. US hams will need to be ARRL members to receive awards and certificates.
Many US hams use both LOTW and QRZ for QSO logging. The reason for using both is that many hams will use either LOTW or QRZ for logging but not both. By using both logging programs, the databases can be downloaded and combined allowing for a larger number of confirmed QSO’s.
On the QRZ sample logbook page note the Stars in the rightmost column. Solid yellow stars reflect QRZ confirmations and Stars with a green circle reflect downloaded LOTW confirmations. Blank entries in this column indicate no confirmation has been received from either QRZ or LOTW.
To use LOTW your identity will need to be verified before you can use the log. The confirmation process takes a few days and will be confirmed by a postcard. You will require a password to get into the LOTW program and another password to digitally sign to upload or download data.

Frequently Asked Questions – LOTW
PSK
PSK Reporter is a freeware program that allows the ham to see where his/her FT4 or FT8 digital signal is being received and how long ago was it received or where a signal in question is being received. It can help to answer the questions such as “is my signal being received in Australia?”
The program can be loaded by using the following URL: PSK Reporter.

Dimension4
Several of the new digital modes used in ham radio require clock synchronization to the second. If your clock is out of sync everything may appear to be good but you may not be able to initiate a QSO. The manual setting of your computer clock is usually not accurate enough for this task. Dimension4 is a clock synchronization program that will synchronize your system to less than 100 milliseconds. It is advisable to always start a time sensitive program (e.g. FT-4 or FT-8) with a synchronized clock. This is usually done as the first step in bringing up your software. Dimension4 is one of the gold standards for this task. The program is free for home use and can be downloaded HERE.
When the program is started a box will display. Click SYNC in the upper right corner and it will handle the rest.
Time.is
Time.is is a URL that when loaded calculates the deviation of your clock from standard. Type Time.is into your browser and it will return deviation. If it is less than 100 milliseconds you are OK on calibration. If more that 100 milliseconds use Dimension4 to recalibrate your computer clock.
