In your statement that I quoted just above this post. You are telling someone to run a radio to 50% duty cycle, that is only rated and certified for 5%. And then you are using that argument to say that the radio is junk because it falls out of compliance when pushed beyond it's design limitations. And you have stated they are junk, that they have failed you, etc, and then made it clear you pushed them beyond what they are designed for.
Anything that is pushed beyond it's design limitations is going to fail at some point.
You are obviously making an assumption based on a collection of multiple posts I have made... and your assumption is wrong.
Actually, the radio in question is rated for a 10% duty cycle; 6 minutes transmit, 54 minutes receive. And I mentioned using the radio in extreme use conditions as a cheap/easy means of detecting if the radio will stay within its maximum deviation. If they can have a 20 minute conversation and not hear any deviation, the radios are performing very well. If they don't get the full 6 minutes of transmit before hearing a deviation, then there is a problem.
I said that BTechs are junk because I have owned several mobile radios that failed within days/hours of ownership. I never mentioned the models, how I used them or what their duty cycle is rated for.
Just to be sure there is no confusion....
I had two UV-50x2's which are rated for 100% duty cycle to build poor man repeaters (also has all remote control features built into it for remote management). I was only using them as mobile ham radios with light-duty use. They both broke extremely quickly while used, literally, for initial testing and configuration. Both radios had less than 20 minutes of total transmit time.
The reason I think the handhelds are junk is because they are built with cheap plastic that has basically zero impact resistance. Also the transmit audio quality is terrible. For the same price as the BTech, I can buy something like an iCom or another mainstream, amazing performer that is also durable. The fact that the BTech units drifted a bit after the duty cycle was exceeded was never a consideration in my opinion of the handhelds.
If you had good luck... God bless you. I haven't. I think after using radio's for work, recreation, and working in Electronics and IT for 27+ years, I'm pretty well experienced enough to develop a opinion on what is junk. You are welcome to disagree and have your own opinions based on your experiences, but please don't put words in my mouth.
