Locked Re: Rig Control Error 40 Meters Only? #FT8

Sounds like RF from the rig getting to the USB cables & computer. Have you
started with a low power out (5 watts) to see if the problem is there?

Try increasing the spacing of your coax & USB cables.

Have you added ferrites to your USB cables?

Just downloaded ver. 2.5.4 and testing showed that it works on 20, 15
meters etc. but not 40 meters? Rig is an Icom 7300 controlled by a Dell PC.

40 meter FT8 receive initially performs as expected but when the
transmission tries to start, the rig switches to the transmit frequency,
tries to initiate a signal but fails and shows the rig control error. The
rig is then receiving on what I believe is the offset transmitting
frequency. Why does this happen on 40 meters and not the other bands?

Is there a problem with the correct offset frequency that I'm not aware
of? I apparently retained and earlier version of the program when I
downloaded the new one. Tried the previous version with the same result.

Well, I'd appreciate any suggestions as to the cause and the solution!
