Question 1: 
I want a USB version, but operating at 915MHz (web site said 880 to 925MHz). Can I configure the operating (carrier) frequency with the software? What is the modulation frequency? (64Khz)?
WENSHING Answer:
Please refer to the following points in response to your previous questions. 1. Operating frequency: 922MHz ~ 928MHz, which is adjustable by software. 2. It would be able to use 915MHz, but it would also reduce the sensitivity by doing so.
