May I suppose that you have a usb to serial com? Maybe you unplugged the usb cable and you plug it to a different usb port. This will give you a different com port. Do a right click to computer and select management. Again management or something similar (sorry my windows are in Greek) and see the com ports. See what com ports your computer has. If com 5 is not an option anymore, note what other ports you have and try these ports in dx4win. All these in case you have a usb to serial cable

Hi All,

My name is Carter Craigie, and my call is N3AO, and I live in Blacksburg,
VA, with my wonderful wife Kay N3KN.

I need some help, and don't know to whom to turn. I hope you will be able to
help me.

Here's my problem:

I have a Yaesu FT-450 radio, and I want it to communicate with DX4WIN, and
with other programs as well. At one time all was fine, but something has
changed, and I am no longer able to make the connection to my Toshiba
Satellite E205. Under DX4WIN's Preferences, it is my Second Radio.

I don't understand COM Ports, and Kay will be the first to tell you that!
Hi!

Surprisingly, when using a SignaLink USB, I AM able to do PSK31 with Mix-W.

Hmmm.

Here is what I see under DX4WIN's Preferences (Radio):Radio: Flexradio

Address: 00

Baud Rate: 9600

Notes for Radio: Flexradio

Com Port: COM 6

Poll Rate: 500

Max Tries: 6

Check: DTR High

Check: RTS High

Transverter: 0

Band: None

Second Radio:

FT-450

Address: 00

Baud Rate: 4800

Notes for Radio: ON4AOI

Com Port: Com 5

Poll Rate: 500

Max Tries: 6

Check: DTR High

Check: RTS High

Transverter: 0

Band: None

What is happening now is that DX4WIN cannot "read" the radio.

I am completely stumped!  Do you have ANY suggestions for me, please???

73,
