The radio is a TK-760G(128ch)K according to the programming software.
148-174 frequency range, no option boards.
I have BCL disabled and all of the frequencies I have programmed into the radio are within the frequency range.
After further testing, I am now only experiencing the “unlock” message/no transmitting on radio channels 3 & 4, all other programmed channels are tx & rx as normal. I’ve checked all the menu options and don’t find anything that would explain or correct this issue. I even programmed the same two frequencies on different channels and they tx & rx as normal. So for now, I just won’t use channels 3 & 4 lol.
Thank you to everyone that replied so far.

PS- thank you for the link to the manual but, I already have a printed copy and can’t find anything listed that would explain or correct the issue.
Thank you both for your response and invaluable information. I’ve been trying to learn as much as I can about this model and I’m surprised that this is the first time I have heard of the TX power reduction “feature”. I can’t thank all three of you that responded enough. This all makes sense now. My friend/tech, I’m assuming adjusted the power setting to 27.5 intentionally, in an attempt to minimize the chances of overheating and since the power is a slow & steady reduction that returns to the full 27.5 on each transmission, it would make sense that it has been programmed to do so for the reason you both pointed out. I did re-check all of my connections again with a focus on my cables and everything seems tight and secure. I’m sure my friend/tech intended on informing me of this feature and to be honest, he may have on the day I picked it up. I either don’t remember or it’s possible I was too busy babbling with his wife (most likely) or since my visits were usually spaced apart by several months, and as friends do, there was always a lot of catching up to do, some show and tell, some gifts and more. My bad for not paying closer attention and taking better notes.
Whether I receive good news or bad, I always receive the information I need from all of the supportive members on this site and I can’t thank everyone that responds, enough, for taking the time to to monitor and offer guidance by sharing their knowledge and experiences with the rest of us.
Until next time (and I’m sure there will be plenty of “next times”, stay healthy, well, safe and happy !
