Re: Fuel Cells, How They Actually Work?

No, not really. Ignoring the issue of where to get the fuel, the advantages of a fuel cell are that it can be quiet, has few moving parts, and emits only water vapor. It's basically a battery that isn't a sealed system, and can be refueled rather than being recharged. But as you observed, it isn't a...

Re: MotoTrbo Audible Tone Over DMR?

Short answer: no, that won't work. Longer answer. If digital radio just sampled the data and pushed it over the air, you would need about 64kbits/sec to handle voice. That would require about 32 to 64 kHz of bandwidth to carry in any reasonable modulation for what we are doing. The point of digital ...

You need to understand that the T/R path adds a 40dB attenuation to the signal, and the TR/Aux RF switch is on the upstream side of that - so the RF leakage "seen" by the receiver is 40dB higher than the real signal. In other words, what you are seeing is operation as designed. Really, if ...
