My normally reliable TH-28A has gone psychotic, I'm afraid...... It was performing beautifully until it started to emit key-pad beeping noises at almost regular intervals; also, it will not TX or RX. I've reset the HT twice, both mem and CPU- didn't work. Checked the mem support batt, and it was 1.25v. I'm stumped! I did a search on the -28A and mysterious beeping, but no luck. Have any other TH-28A owners had, or heard about this problem? If the problem is terminal, it does give me a plausible excuse to buy a TH-78A, -79A or suchlike. I do revere the older Kenwood HT's. They set the standard for aesthetic "Cool" that no HT's have ever surpassed.
