@IronArcher No, it cannot be done, b/c it doesn't really matter. I've been sharing some ISO-tee tests figures here, and all I get is people arguing personal opinions, swirling personal attacks and sowing doubt, deflecting from the problem at hand, while painting me as someone who is trying mislead people, etc. So, I've decided its just better to silently laugh watching people fumble around with garbage equipment, always wondering why their ranges are only a tenth of a mile, than me getting all worked up, writing long posts trying to explain things that noone cares. And why it doesn't matter to have any spec chart, of any sort? Well, its very simple: Because we are cheap. Lets just say we had a chart with a bunch of radios, so, you see that fancy XPR7550e, and everything looks great, a +18dBm better effective sens, tight selectivity, and better everything... so you quickly realize this is the radio you want, but then, finally, when you look a the last column, the pricetag... you have a heart attack.... so in your mind you quickly disqualify the XPR7550e, b/c none of things can be that much better than the 59 dollar garbage CCR special... so without having any sense of what a 18dBm difference truly means, or any of the other spec chart parameters mean, all of the sudden, that 59 dollar CCR garbage special becomes the best radio, the same radio Jesus used to call Home before ascending back to Heaven... Seriously, it doesn't matter. Only way to guarantee learning is making mistakes over time, and if it has to be an expensive mistake over a long period of time, so be it. The more expensive the mistake, and the longer you've made it, the better you learn the lesson, and I can certainly attest to heart to that... until then I'll be laughing... yeah, I am a cruel person, I am gMan the heartless, the troublemaker, the troll... etc etc. G.
