Tom, If you are using MMTTY for FSK with a USB-based device, then in the MMTTY setup under the Misc tab where you select COM-TxD(FSK) for FSK keying, you must also click on the "USB Port" button and select option C. Limiting Speed. If you don't do this, MMTTY will release PTT as soon as the computer has finished sending the data to the device at USB speeds, which happens long before the radio has finished sending the data at RTTY speed. 73, Rich VE3KI ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
