760 Kenwood Scan promblems

[Jose_Rogers]

Hello group, I have a 1 owner, 760 Kenwood radio that i have used for apx 20 years. Since I have owned it, I may have only programmed it 5 times. Its been a great radio with NO problems. Just recently I noticed the scan button when pressed will not work. If i press the scan button , it will make a loud BEEP. ok... now thats trying to get it to scan mode. I can leave it in manual mode (lack of terminology) and use the up and down buttons and and i can change the channels to any channel i want to, but i just can not make it "Scan". So i figured i would reprogram it. Programs perfect... on the first try. then I try to make it scan and it will not scan.... I have never changed any of the settings on the radio or program. I can only do manual mode only.

Would the microphone cable if it had a brake in one wire, would that stop the scan operation....? I can still key up and talk no problem....

I don't understand "Firmware" I know that is different from the regular programming software. But if I programmed a new firmware to the radio would that fix it or am I just wasting my time. Would like to thank everyone in advance for there thoughts and input. Please explain it to me on a childs level so maybe I will get it...... thank you all and have a great day....

Hello group, I have just found my problem. I have a metal mic clip that came with the radio when I bought it new years ago. I have worn out the "do-hinkies" don't know the name but are 4 of them, on the mic hanger. So its not allowing my mic to make a connection. The radio thinks i have the mic ready to use but really the mic is hanging on the mic hanger. I applies pressure on my mic and hit the scan button and its fixed.... thats all it was......Thank you all have a great day...

Yes, the mic must be hung up, AKA grounded, for the Scan to work. Same on most other radios.

scan issue

You could also program the radio to "off hook scan" and it will scan regardless of the mic. It should go to priority when mic is keyed, but will scan until scan is toggled off

And replace the metal Mic hang up clip. There are many different ones or types out there. Get a original Kenwood part, I do not have the part number, but someone can chime in with the part number.

You can open the mike & ground it internally. I just had to do this yesterday to a Kenwood KMC-9 base mike which was preventing the radio from scanning. All fine now.
