[WriteLog] ICOM 7600 WL bandmap zerobeating

Gilles,

I think Joe has the Rttyrite ini command wrong.  I can't find anything in 
the Help manual about CW_RECV_FREQ.  It should be

CW_XMIT_FREQ=750

This sets the transmit frequency to the center of the Writelog CW Receiver 
window.  The span of the window is +/- 250 Hz from this center point.

As Joe says the way to set the CW offset pitch is to press and hold the 
Filter button for 1 second.  Then rotate the CW Pitch knob on the 7600 which 
changes the pitch from 300 to 900 Hz in 5 Hz steps.  The actual setting you 
are at shows in the filter setting display along with that filters upper and 
lower limits as you adjust the CW Pitch knob.

Another trick I've found to compensate for the spot frequency being slightly 
off is to use the MouseWheel command in the [Configuration] section of the 
writelogini file.  For CW I use the following:

Mouse_Wheel_Hz=50

Then if the frequency is off a bit just move the mouse wheel up or down one 
click at a time.  With each click of the mouse wheel the frequency will 
change by 50 Hz.  Set a larger or smaller value if you prefer.  Just 
remember to use this for S&P only as it changes both the receive and 
transmit frequencies.

73,

The trick is to set the Writelog CW Receiver to the CW off-set that you like
to hear.  I think the default is 600 HZ but I prefer 750 HZ.
You have to make an entry in the Writelog.ini file like below:

[Rttyrite]
CW_RECV_FREQ=750  Set it for whatever you frequency is.

THEN you have to set the CW Off-set in your IC-7600.  You might have to look
at the manual, but on most of the newer Icoms you press and hold the "Filter
button" while in the CW Mode.  You can then adjust your rigs off-set to
match Writelog offset.

Then if you use the CW Receiver to "tune-in" a station, you will be zero
beat,  if you click on a spot, then it should be right on freq.
hope this helps?

On this weekend CW contest.

I remarked on the Writelog bandmap that when I left clic on a yellow
underline call, when I TRX I am a liitle off of his frequency, and I must
readjust for few cycles the VFO.

What is the procedure to zero beat as much as possible the icom 7600 to be
as close as possible of the bandmap  and other station freq.
