IC-7300 defaults to LSB for CW

Post by G0DJA »

OK, I've checked on search and I don't think this has been covered.

Before anyone asks, this has nothing to do with LSB being below 10MHz and USB above, this about the setting in "Function" > "CW Normal Side". This affects which side of the dial setting the CW note appears. So, assuming a 600Hz note, LSB will give a tone 600Hz below the dial setting and USB 600Hz above. If you are listening to a signal you won't notice any difference but the problem happens when you start to try and tune into the signal that you want to receive.

If the Setting is LSB you have to tune down and if USB you tune up. personally, I prefer to have the "CW normal side" set to USB so when I'm tuning I approach the signal from below and tune up. LSB seems counter intuative to me.

Whenever I start, or have to restart, LOG4OM it sets the "CW Normal Side" to LSB and I have to remember to go into "Function" > "CW Normal Side" and reset it.

Is there a setting in the INI start up file that will let me change this so it sets it to USB?

Thanks.

Program config/CAT interface - check or uncheck 'Invert SSB side (CW)'

Thanks for the idea, it didn't work but I think I've found out another option.

I use OmniRig to control the radio, and in that programs INI file is a command

[INIT3]
;set CW normal to lower sideband
Command=FEFE94E0.1A050053.00.FD
ReplyLength=16
Validate=FEFE94E01A05005300FD.FEFEE094FBFD

Now I need to find out what the command and validation code need to be changed to.

I found a way to stop it happening. In OmniRig I used the ";" sign to stop the [INIT] command that set it to LSB from working and that seems to have cured the problem.

So, it wasn't a problem with LOG4OM after all. I'm including this information in case any other user of Icom radios has the same problem.
