FW: [Discuss-gnuradio] question about BasicTX

[Li Mei-Wen]

Hi:
 
I am trying to transmit in 88~108MHz (FM bands)
I know it have license, but it just research in Vehicular Network.
 
>What kind of antennas you have?
 
I just use car antenna, have better antenna for BasicTX?
Or have other way to add the gain/output power?
 
 
And I try  /usrp_siggen/.py , It can't work.
 
emily /usr/src/gnuradio-3.2.2/gr-utils/src/python
$ ./usrp_siggen.py -f 90M -a 32000
Using TX d'board A: Basic Tx
 
Have anything I missed ? 
 
 
Thanks in advance.
