K3: TX INHIBIT error

[ab2tc]

Hi,

K3 #82 has a new home here in Central New York. I am having a blast with it in the WPX contest.

It has developed a minor problem. After a while, the TX icon below the [A] display label sometimes starts flashing and the radio will not transmit. If I use the XMIT button to key it, the message TX INHIBIT is shown in the B display. Turning radio off and back on instantly cures the problem (haven't found any other way). I doubt if anything is overheating, I am only using SSB with a relatively low duty cycle.

Note that the radio is *not* in TEST mode as suggested by some at the Yahoo forum. The symptoms are different as the radio will not enter transmit mode at all. I hope this is not anything serious. It does look like this will only happen when the radio has been on for several hours, not necessarily transmitting a lot.

There is an item in the CONFIG menu called "TX INH" that you should
check... It should be "OFF" unless you have set something special up.

Thank you! Sure enough, it was enabled, so I turned it off. This feature must be recent, since it is not in the manual. My firmware is up to date. This will probably cure this problem.

Case closed. This has not happened again.
