[Discuss-gnuradio] Using UHD with one USRP and trying to verify that Im sending data

I have on USRP and I'm simultaneously sending an receiving data from it using the UHD interface. Im trying to determine if I am sending my samples at all. I am sending all 100's using COMPLEX_FLOAT32 interface. I have a basixRX and basicTX boards. Both are hooked up on the A side of the USRP. I have a cable connecting TX-A to RX-A with an attenuator in the middle. I transmit but do not seem to see my signal. Here is a dump from my program.
-- Using Device: Single USRP: Device: usrp1 device Mboard: usrp1 mboard - 48cc208a RX DSP: usrp1 ddc 2X + hb RX Channel: 0 RX Dboard: usrp1 dboard (rx unit) - A RX Subdev: Basic RX (0x0001) - AB
TX DSP: usrp1 duc 2X TX Channel: 0 TX Dboard: usrp1 dboard (tx unit) - A TX Subdev: Basic TX (0x0000) - AB
Setting RX Rate: 250000.000000 sps... Actual RX Rate: 250000.000000 sps...
Setting RX Freq: 4.000000 Mhz... Actual RX Freq: 4.000000 Mhz...
Setting RX Gain: 0.000000 dB... Actual RX Gain: 0.000000 dB...
Setting TX Rate: 0.250000 Msps... Actual TX Rate: 0.250000 Msps...
Setting TX Freq: 4.000000 Mhz... Actual TX Freq: 4.000000 Mhz...
Setting TX Gain: 0.000000 dB... Actual TX Gain: 0.000000 dB...
LO Locked = 1 -- I have also removed the attenuator for a short while but still see no signal.
