Check ins using Fldigi, mode Thor22, 1500 Hz on the waterfall. Turn on RxID and TxID. Turn off AFC and SQL. Be prepared to send your callsign, name, location and traffic. Here's an example.

NY3J RON BENSALEM PA QTC

QTC = traffic and QRU = no traffic. Forcing a line space before and after your check in makes it easier for net control to read the information. You can create a macro like this.

<TX>

NY3J RON BENSALEM PA QTC

<RX>

The <TX> will turn on your transmit and <RX> will turn it off. In Fldigi go to Configure, ID, RsID and set your Pre-Signal Tone to 2.0 seconds. Check your audio level by transmitting into a dummy load and listen with another radio. Too little audio drive and you won't activate your VOX/PTT. Your audio above VOX level should not be too loud to distort your signal. For receive unscquelch your radio and make sure the audio is strong enough so the the receive triangle is green.

The power of Fldigi is sending traffic with Flmsg so take this opportunity to prepare a message even if it's just to say hello. Experiment with various forms. When directed to send traffic click Autosend, click Save to save your message and it will automatically activate your TX to send your message.

After traffic we will continue to talk about JS8CALL which is as robust as FT8 but is used to chat with stations. The latest version of JS8Call and documentation is available here:

The support group is available here:

Go to the settings by clicking file, settings. Make sure your call and grid square is set up. Under you radio tab set Rig None and PTT VOX. Under Audio make sure that your input and output is set to your USB Audio Codec. The audio level setup should be the same as Fldigi. Look at the level meter on the bottom left under CAT. The scale should be about 1/2 during receive. The slider on the bottom right should be 3 or4 notches from the top. The bottom green progress bar determines when you transmit and when you receive and decode. Remember to check your time and use the operating system to adjust it. For Windows 10 turn the automatic setting off and back on. Any questions or comments let me know.
