Just purchased a FT-736R and I love it, except for 2 problems, the CAT comes on by itself, and occassionally the radio will key up automatically. Guide For Detecting Drunk Drivers At Night. When the radio is on for a good length of time I will notice the CAT indicator is lit and I have no control of any functions except TX & RX on the frequency it's on.

When the radio is in memory scan it doesn't seem to happen, but I can't be sure. I am wondering if there is a program in the CAT calling it on. I have done a master reset, before that the AQS would come on by itself, but that hasn't happened since. Line 6 Fbv Shortboard Mkii Guitar Footswitch Review. How can I see if the CAT is on or off. Fs Global Real Weather V1 72712. David W4DWR. Curious Do you have anything connected to the CAT interface on the back of the radio?

I have owned my 736 since 1996 and never had mine come on by itself. When I start the program I use to control the radio, the interface activates but when the program is closed the interface shuts off. If you have anything connected to the CAT interface remove it and see if you still have the problem. If the problem clears up build or buy another interface and try that. If nothing is connected, your CAT should not engage and there is nothing built into the radio calling it to come on. If it is there may be something wrong with the radio. The CAT circuit should never activate by itself at any time especially if you have nothing connected to the CAT port.
