Juan Jiménez All Messages By This Member #54052 Remove the control head from the chassis, disconnect the head cable and check for dust or other debris/damage. Reconnect and ensure proper seating. toggle quoted message Show quoted text On Mon, Jul 1, 2024, 17:04 Seammus via <Seammus=[email protected]> wrote: No. No "KEY" showing. Sent with secure email.

It worked..for a minute.? But, it didn't last and went back to my original complaint. Sent with secure email.

Juan Jiménez All Messages By This Member #54054 Try a different cable. If the problem persists your might have a bad control head. Replacements are readily available. toggle quoted message Show quoted text On Sat, Jul 6, 2024, 07:20 Seammus via <Seammus=[email protected]> wrote: Thanks k1prc.? I did as you advised.?

Kent Trimble, K9ZTV All Messages By This Member #54055 开云体育 Remove the control head again and, with a Q-tip and/or cloth saturated with Deoxit, clean any and all contacts you can get to. That the buttons "worked for a minute" sounds to me like a possible oxidation issue, especially so given the age of these radios. 73, Kent K9ZTV toggle quoted message Show quoted text On Jul 6, 2024, at 6:20?AM, Seammus via groups.io <Seammus@...> wrote: ?
