Hi:
I used USRP1+BasicTX, USRP1+TVRX and ./benchmark_rx/tx.py to transmit packets
but used different bitrate (35K, 125K, 216K) in FM bands (88Mhz~108Mhz)
Why the 35K can reached distance longer than 125K and 216K.
In my implementation result, the 35K was 20m, 125 was 18m and 216 was 16m.
Why

Hi:
How can I get the receive signal strength (db) from usrp_wfm_rcv.py or
benchmark_rx.py.
Or have other way can do?
Thanks in advance.

Hi:
How to get the FM receive data (like: burst dBm, signal strength, timer,
frequence range, distance...) from benchmark_rx.py or usrp_wfm_rcv.py files?
Or have the other way?

Thanks in advance.

Dear all:
I use cygwin and Basic_TX, I test the usrp_siggen.py, usrp_fft.py and
usrp_oscope.py, but they seem can't work.
In any frequence it seem have not different, even I transmit packet in the same
frequence.
And the usrp_siggen.py may can't work, have not anything happen, sometimes ha

Hi:
Why the Basic-TX can not use ./benchmark_tx.py on 50~83 MHz?

Dear All:
I want to use Basic TX to transmission signal by 100m distance.
But I can't reach the distance.
Have any way to help it?
In hardware I added the gain booster (30dBm)
But I only got 5 m.
They be caused by hardware? or the software can help?
Thanks in advance.

Hi:
I use benchmark_rx.py and benchmark_tx.py to send file to receive side.
But, If only one packet, it always false or the last one packet always false.
If I let it sleep ( time.sleep(1) ), the next one packet also was false.
Why? And How to solve it?
And the other question, How receive side
Hi:
Why the benchmark_rx.py always can not receive the last one packet?
Have any way to solve it?

Have anyone use BasicTX and TVRX, did you used amplifer?
What's amplifer or antenna amplifer do you use, can you tell me, that let me

Can I use the FM frequence to transmission file/data to receive side?
If can, how can I do?
Or which files I can modify and reach I want.

I need use some tools, they need modify the /etc/bash.bashrc file (In cygwin)
Add follow words

export PATH
But, If I do this, I can't run gnuradio example files, like follow error:

I install other tools in cygwin, and when restart cygwin, it occur this

Hi:
I want to try my daughterborad basic_TX and TV_RX.
I try to use ./benchmark_tx.py -f 100M and ./benchmark_rx.py -f 100M
Only the ./benchmark_tx.py can run, The ./benchmark_rx.py can't receive any

So, what's wrong about this? How can I do?
Thanks in advance.
