| # RTTY operation

You can operate RTTY or PSK direct out of RUMlogNG using the contest and dx-ped module. ESM is supported. Fldigi or a K3/KX3 can be used as modem. Make the required settings in the Contest Preferences under the RTTY tab: Menu–>Contest–>Preferences.

If an interface configured, the RTTY drawer opens when the operating mode is changed to RTTY or PSK. Fldigi must be started separately. You have to enter the tcp/ip address for the Fldigi xml-rpc port in the logbook preferences under the TRX#1 tab in the Fldigi section.
If you use a K3/KX3, you have to set the mode to FSK-D or PSK-D and you have to enable the text decoding feature. CAT must be working.

The RTTY window has 3 parts. The received (yellow) and the transmitted (white) text will be shown in the upper part.
You can pre-type text into the lower field. Use the button “Send text” (cmd K) to start transmitting. Following keyboard entries will be transfered directly to the interface. The button “Receive” (cmd R) switches PTT off, after the whole text is sent.
To abort the transmission, the Escape key can be used always.

A table with decoded callsigns will be found on the right hand side.

### Callsign recognition

Callsigns can be pulled out of the incoming text stream. You have to load a SCP (Super Check Partial) database first: Menu–>Online–>Load SCP
Words will be interpreted as callsign:

- Callsign is already in the current logbook - green (red when dupe)
- Callsign is in the SCP database - cyan
- Words following a “de” - gray

Not recognized callsigns can be copied to the callsign field with a double click. When the field is always filled, the double clicked text will be copied to the NUM RX field!

### QSO

The curser can be kept in the callsign field to select a callsign.
You can operate RTTY in the same way as you would work in phone or CW and enter all data manually. It is more convenient to use the found callsign table:

- Use the Arrow up/down keys to select a callsign from the table.
- Use the Space bar to copy the selected callsign to the callsign field
- Use Enter key to copy the selected callsign to the callsign field and to start the exchange
