Just wanted to ask about tsbks...what does this stand for? Is this like a data counter? Also the number in parentheses next to the frequency what does that number indicate? Thank you!

There's really not a "right" answer. You want a low noise floor and a strong signal giving you a low SNR and solid decode.Hey,@boatbod In reference to LNA what is the optimal Noise Floor to Reception (DB)(Gnuplot 5)? Sneaking a quck question in before the weekend gets kicked off![]()
I've been toying with 20-25-40 20 is good when the system isn't busy....bump up to 25 I see the noise floor spiking a bit but still good decodes I'm going to rock out with 20 for a Saturday night because I don't get the crazy mic chirps. Site is 10 miles away getting-40db and -90 on noise floor only worry is im missing out on transmissions but it sounds so cleanThere's really not a "right" answer.

Increasing the LNA gain usually increases the noise floor at the same time, but it's not a linear relationship, so the usual methodology is to increase LNA until you start seeing the noise floor rise significantly, then back off a bit.
-40db signal with -90db noise floor sounds like a solid decode. How tight are the constellation plot clusters? Ultimately that's the real metric for how good a signal you are pulling in.I've been toying with 20-25-40 20 is good when the system isn't busy....bump up to 25 I see the noise floor spiking a bit but still good decodes I'm going to rock out with 20 for a Saturday night because I don't get the crazy mic chirps.
