Which one of these scanners pick up more signals than the other? Also how does the HP-2 receive in comparison? I heard that the 436 and the 536 are the ame radio it is just that the 536 has a bigger speaker.
I'm sure you understand the 436 is a handheld portable and the 536 is a mobile/base type. Specs look identical; perhaps a few feature differences but nothing major pops out. And in regard to the signal; that would totally depend upon the type of signal, antenna, your location, etc. I have the 536 and it works great, although I do not have an external antenna for it at the moment. I would like to have a companion 436 for portable use but the funds are a little shy at the moment.
