Mortty v4 Uses Identical – and Simplified – Sketch Upload Methods for all three supported sketches
INTERFACE RTTY FOR MAC
Furthermore, if you do not use the Windows Operating System, fldigi’s multi-platform software for Mac and Linux users supports Mortty in a non-Windows world. If you are an fldigi user or if you want to be able to switch instantaneously between RTTY and CW, then you will want the nanoIO sketch.
This requires, of course, that you have chosen the fldigi software as your digital program. The fldigi nanoIO sketch offers something that the other two cannot – the ability to switch between RTTY and CW modes by a simple menu choice in fldigi. If you want to operate accurately timed FSK RTTY and use N1MM, WriteLog, DXLab, Logger32, DX4WIN, MMTTY, 2Tone, fldigi… and many others, you want the TinyFSK sketch. The TinyFSK RTTY sketch is a time-proven RTTY modulator and is supported by most of the popular RTTY software and logging programs. Mortty v4 triple output for SO1V, SO2V, and SO2R CW operation is described in the installation and operating manual. If you are a CW operator and want an excellent CW keyer (but no RTTY), this is the sketch you want. The CW Keyer sketch delivers a very faithful emulation of the popular and widely supported Winkeyer version 2.3.
INTERFACE RTTY INSTALL
However, if you decide to switch to a different sketch, or install an update to your current sketch, changing sketches on Mortty v4 is fast, easy and fully explained in the documentation. The latest version of your preferred sketch is pre-installed on Mortty as your order is prepared for shipping. Mortty’s behavior is determined by the program (“sketch” in Arduino-speak) that runs on Mortty’s Arduino Nano. W1HKJ’s nanoIO Dual-Mode Sketch supports both CW and RTTY operation using fldigi.K0SM’s TinyFSK keying via widely supported RTTY FSK protocol.
