and the "RUB OUT" ends the programming and changes the display back to your original page.
The "CR CR LF" sequence at the beginning and end of the text is optional – it will help assure that
the other station's RTTY equipment prints your ID on a separate line.
Next, transmit the HERE IS #1 message with the "CTRL-R":"1" key sequence. A reverse video "1"
is shown in the transmit buffer area; when transmitting is enabled (with SEND switch or with AU-
TO - CTRL-A or CTRL-X as explained in the previous section), the text of HERE IS #1 message is
placed on the blank line of the screen above the status letters and then transmitted. If the "call" to
the HERE IS message were included in other keyboard typed text, the reverse video number will
be entered at the appropriate place and be transmitted only after proceeding text has been trans-
mitted. For example, suspend transmission temporarily and type three or four words, then "call"
the message (with CTRL-R:1), and type several more words. Now, enable transmission and watch
how the HERE IS message is expanded and transmitted when its turn comes.
The same procedure works for programming and reading all 6 HERE IS messages. HERE IS #0 is
special in that a CW ID may be included within its program. An example of a HERE IS #0 program
is:
Type: "CTRL-W":"0"
See: Page 3 of display
Type and see: "CR CR LF DE JOHN, WQ9XYZ CR CR LF * DE WQ9XYZ * CR CR LF
(* in reverse video)
Type: "RUB OUT"
See: Original display page.
This example will send both an ID in RTTY and then switch to CW at the reverse video star (*),
send the "DE WQ9XYZ" in CW, and switch back to RTTY for the final "CR CR LF" sequence. The
CWID A/CWID B front panel switch makes a difference here: in CWID B position, the CW ID is
transmitted using mark-space AFSK; in CWID A position, the CW ID section is transmitted on the
CW key output line as well as the FSK data output line. Host RTTY operations where AFSK tones
are used on the microphone input jack should use the CWID B position; you may use CWID A for
CW or when you are using direct FSK of a transmitter oscillator. Notice that the phrase "CW ID
FOLLOWS" was NOT included in the above example - it isn't necessary, especially if the CR/LF
commands are used to prevent garble overprint on the other station's printer. Try "calling" this
HERE IS 0 message while transmitting text. Listen to the output tones and try both CWID A and
CWID B switch positions.
The switch between RTTY and CW AFSK can be made anytime in the typing of transmit text and
does not necessarily have to be included within the HERE IS 0 message. If you wish to insert a CW
AFSK section within a typed RTTY text, type a "CTRL-Z":"SHIFT-*" command before and after the
CW section of text. The stars will be written into the transmit buffer and the CWR6850 will auto-
matically switch to AFSK CW when it encounters the starred section. Another command, "CTRL-I"
will switch the transmitted output immediately from RTTY to CW for whatever text remains in the
transmit buffer. A second "CTRL-I" will switch back to RTTY. The switch is indicated by a reverse
video star ( * ) in the echoed text in the receive buffer.
The contents of all six HERE IS memories may be transferred to tape and be reloaded from tape,
thus saving them during times that the power to the CWR6850 is turned off. To save the HERE IS
messages, use the following procedure:
