Hello to All of YOU!
I'm looking for an advice on two questions:

1. What radio should I buy between the two: Yaesu VX-7R or Kenwood
TH-F6A
2. Where should I buy it from (price) or maybe someone sells one used ?

the first question: I want this radio in order to be able to
monitor (listen) to all possible things: weather, radio, police chat,
trackers, taxi dispatchers an so on.
Also I would like to be able to talk back to some of them (definitely
not a police )
If it's matter, I'm in San Francisco, CA and love to hike in Lake Tahoe
area of the Sierra Mountains.

Most frequencies REQUIRE some sort of license to "talk back".
It's unlikely that either radio can be used legally transmit outside the
ham bands.
Get a trunk-tracking scanner. Use your cellphone for talking.
