My VX-7R is acting strange.  Was working great all week and then all of a sudden the frequency display started blinking and when you push the PTT switch the TX display shows that I am transmitting but it is not doing so.  When I release the PTT swt. the display appears to still be transmitting but it is not.  I have to turn the radio off before it "releases" the transmit indication. I tried set mode reset and that did not help so I tried microprocessor reset and that did not help.  Is there anything else I can do to fix this problem?

Thank you for your help in this matter

Are you running this HT on its own rubber duck, or through an amplifier with an external antenna?  I had a similar problem years ago using a 2m HT to a 2m amplifer to a mag-mount - and the radiation from the amplified signal was getting back into the HT and causing an oscillation - had to power the whole thing off, not use the amp with the HT mobile.

I don't know about your particular radio, but I've seen similar problems when one or more cells of the main battery is kaput. It's also a good idea to check that the  memory backup cell isn't on its last legs.
