Hi Andreas, thanks for the hint. However I am using a Ettus B200 and do not have access to a different SDR right now. I will test outside and then trying to find out what is going on. BR Mike > Hi Michael, > > i read your mail and i could remember i had a similar problem with a lot > of lost s

Hi Mike, the B200 should usually be a little more reliable than the RTL dongles; what gain setting are you using? Best regards, Marcus On 08/25/2015 02:08 PM, Michael Thelen DK4MT wrote: > Hi Andreas, > > thanks for the hint. However I am using a Ettus B200 and do not have > access to a different

Hi Marcus, I hoped so, that is why I bought one ;-). I think the max is 73dB. The actual value I set with a slider is 90dB. Thus I am pretty much maxed out there. But like I wrote earlier, that is the only way to receive at least one station. Don't have good RF working conditions. Even cellular is

Hi Julian, I managed to finally get data across…I was leaving the payload to automatic (0) and it turns out I was sending messages less than the default of 512…I knew it had to be something simple and there it is. I change the payload to 8 and now it will send messages greater than 8 character

[Discuss-gnuradio] Better approach for FEC

2015-08-25 Thread bob wole
Hi, I have a burst system in gnuradio which is working fine with usrps. I have used tags (tx_time, tx_eob and tx_sob) to define packet boundaries and transmission time. Tags are inserted by a block which is connected before the usrp sink. I did not use any "tagged stream block" in the burst system

[Discuss-gnuradio] USRP's not Communicating

2015-08-25 Thread John Garrick
Hello, I want to transmit the data between two USRP's and make them communicate with each other. But I guess the packets are not being received properly. I am connected the two USRP's to the same laptop and trying it. Is that applicable? I mean, will it work if I do that? Or should I connect to tw

You can have each USRP on the same computer or not, that shouldn't matter. I've done this test with some USRP2's and I remember what we did was transmit a CW tone from one to another and measure a frequency offset (maybe 10s of kHz?). Basically, transmit a tone at some known frequency (like 200 M

Ah sorry I wasn't specific. This was from years ago, the numbers I used were just meant to be an example, not accurate. On Tue, Aug 25, 2015 at 10:25 PM, Marcus D. Leech wrote: > On 08/25/2015 10:17 PM, devin kelly wrote: > > You can have each USRP on the same computer or not, that shouldn't ma
