i) Now you can listen to your own transmissions - volume set to 40% of received transmissions.
ii) I've added an Exit button at top right of main screen that really terminates it. The Android Back and Home buttons don't terminate 'Morse Intercom' just puts it in the background - you will still hear received messages.
iii) You can predefine up to three message strings which can be copied into the 'Message To Send' field using a two character escape seqence - '#0' '#1' or '#2' (great for your initial CQ call).
iv) Especially on small screens, it is difficult to tap exactly where you want to insert text. In the 'Message To Send' screen the '<' and '>' characters can be used to move the cursor left and right if your tap didn't quite get it right!
NB: '#', '<' and '>' don't have Morse equivalents, so can be co-opted for these alternate uses.
This app allows Android/Windows/Mac devices to send and receive Morse (CW) messages to and from one another across a Local Area Network (wired or wireless).
Many radio amateurs still use Morse (Continuous Wave or CW). This app converts your text messages into perfectly spaced Morse at your selected speed and transmits this to any listening stations. Receiving stations can type a reply which will be sent back to you in Morse!
The 'show last message' button will display the text version of the last message received if you couldn't copy it 100%.
Set 'My Callsign' to your amateur radio callsign if you have one as these are guaranteed to be unique, else to a unique string such as an email address. This version of the app only works on your local area network, so 'john', 'jill', 'fred' etc should be OK as 'My Callsign' values.
The 'Remote Callsign' should be left unset to emulate 'real' Morse - every listening station can hear what you send. But if you set the 'Remote Callsign' before sending a message, only that station will receive the message.
Transmit speeds can only be set to 8, 16, 24 or 32 words per minute, the receive sidetone only to 400, 600, 800 or 1000 Hz, and the channel must be left set to 1. The new popup screens to select these all show additional (greyed out) radio buttons. These are for a later version, and selecting one of these buttons will not change the current value.
I've added a new 'Add Standard Text' button which is easier to use than explain how to use! It allows you to define up to three 'canned' text strings that can be copied into the 'Message To Send' field by tapping the escape character '#' followed by the number of the standard text field '0', '1' or '2'. You must be 'in' (have tapped inside) the 'Message To Send' field for this to work. So, for example, a standard 'CQ CQ CQ ...' message of 19+ characters can be defined once, but used at the start of each new contact by tapping just two characters ('#0' '#1' or '#2')
You need at least two devices running this app attached to your LAN to start communicating in Morse. Not all these devices must be Android however. If you only have a single (or even no) Android device but one or more Windows/Mac desktops/laptops you can install a compatible app for these.
http://www.program2anything.com/morseintercom.html contains a web based version of the intercom that runs in your browser. It can be used as a second intercom if you only have a single Android device. There is also a standalone version that can be downloaded and installed on your desktop/laptop.
