Thanks everyone for the info.
I have what appears to be a two trace version, 900Mhz, and to be honest it appears to be satisfactory.
No crashes etc.
Although there is one thing that I have not yet played with, and that is how to sweep a small signal range for xtal filters.
I have heard that there are frequency rounding errors on some versions, but I cannot determine if I have that issue because
I'm not sure how to set it up for a sweep, and advice greatfully received.
Not too fussed about a battery indicator, since I think it already has one, if I turn it on and there's no display then battery = dead ;-)
I quite like the idea of an auto find lowest SWR etc function, that could be useful, but no deal breaker, I just zoom in a bit more.
So, I guess that I may have aplay at some time,but I'm not in a rush.
