I am trying to make an OFDM transceiver using my USRP1.
I used the existing examples of GRC. (tx_ofdm.grc and rx_ofdm.grc)
I am having problem in the communication while i transmit in HF band
using LFTX and LFRX daughterboards.
The model is working fine when i transmit at 700 MHz using flex900
Thanking in advance.
