[Elecraft] New K3/K3S firmware handles CR/LF characters in RTTY and PSK modes

[Wayne Burdick]

Hi all,

We're looking for a few testers for the latest K3/K3S field-test firmware. This rev fulfills a long-standing request to properly handle carriage-return (CR) and line-feed (LF) characters in our built-in data modes, FSK-D and PSK-D. CR and LF characters are used for screen formatting, automatic spotting sequences, etc. 

FSK-D and PSK-D modes use the radio's DSP for encode/decode, with text input provided via an attached CW keyer paddle, a keyboard connected to a P3, or from any computer application that can send remote control commands to the radio. One of these applications is K3 Utility. It includes a Terminal screen that works in RTTY/PSK31/CW modes. (We have a bit more work to do in K3 Utility to handle CR & LF characters in transmit mode, as I'll explain in my instructions for using the new firmware.)

This release also fixes a recently discovered PTT bug. Unexpected ERR PTT and ERR KEY messages were being displayed if the operator activated PTT, then tapped A/B, etc.

If you have time to test these improvements in the short term -- preferably this weekend, so we can go to beta next week -- please contact me directly.

73,
