[Elecraft] How does fskd work on the k3?

[Richard Ferch]

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.
