Access to port denied

 

Lately when running N3FJP the program keeps up with my Yaesu FTdx1200 but then I get the msg Access To Port Denied.? I'll try Rig Control and get that msg again.? Then I'll reboot N3FJP and/or my PC and N3FJP now works again.
?
I went into Device Manager and made sure it duplicated the correct port settings, thinking that might be the problem.? But this morning I again ran up against Access To Port Denied after a while.
?
What's the answer?? Appreciate help.
?
Thanks.

You might make sure the USB port is not powering down automatically

Are you running additional software prior to starting n3fjp software

I have seen this behavior when RFI is getting into your computer or com port on the radio.? Try reducing power out and doing whatever activity causes this behavior.? ?If it stops then you are having RFI.

Make certain you have good USB cable; not the cheapest you could find. Put ferrites on all the cables between computer and radio. I recommend the Palomar kits designed for your specific radio.
