[Elecraft] Re: CW pitch can go to zero Hz (RS232 problem)

[wayne burdick]

Carl,

The character '@', when embedded in a "KY<text>" CW keying packet, will 
do one of two things:

1. terminate the transmission, or
2. send .--.-. which is the Morse pattern for '@' (you can also think of
    it as the prosign "AC")

To select which behavior you want, go into CONFIG:CW WGHT and tap '2' 
on the keypad. You can select either "@=STOP" or "@='AC'". The latter 
is useful if you want to send e-mail addresses in CW. In fact '@' is 
the newest Morse character and was adopted for just this purpose.

The problem you're describing appears to be with "@=STOP" selected. 
I'll see if I can duplicate this. Meanwhile, you might want to change 
it to the "AC" prosign.

There are two other "meta" characters that can be inserted into an 
ASCII text packet: '<' (go into TX TEST mode) and '>' (exit TX TEST 
mode). These and '@' are documented in the K3 Programmer's Reference 
(available on our K3 page). Refer to the 'KY' command description.

Let me know if this helps--

73,
Wayne
