Re: [Hackrf-dev] hackrf with gqrx on low end of HF

If you're receiving, don't use the RF gain - use the IF and BB gains. If you're transmitting, be careful, assuming no loses, 10 mW of reflected power may fry the RF amplifier. And note, there most likely a DC offset on the center frequency. You should use hackrf_transfer -r /dev/null to test

Re: [Hackrf-dev] Narrowband fm - what is the secret?

Hi - neither APRS or AFSK are FM modulated. AFSK is digital and uses 2 frequencies - FM is analog and uses a wide range of frequencies. APRS is packet based and you need to decode it - which is what your handset is doing. See if SDR has a APRS decoder plugin. Note, gqrx has a APRS decoder. --

[Hackrf-dev] beaglebone black rev c

Hi - I'm running hackrf_transfer -r /dev/null on the BBB, and I have to drop down to a sampling rate of 4 MHz to avoid dropping data. Is this normal for the BBB? I vaguely remember someone claiming to be able to use a sampling rate of 10 MHz. I'm using a wart power supply on the BBB and conn

If I recall correctly, if you add the shield and then the case, there is no improvement. What we don't know, is if it makes any difference if add the case first and then the shield. -- Cinaed On 04/27/2016 04:56 AM, Don Gray wrote: > I'm back "on the air" with a new HackRf thanks to the excelle

Here are transmit powers https://github.com/mossmann/hackrf/wiki/HackRF-One I modified the lines from wiki so I don't have to do a mental back flips 10 MHz to 2150 MHz: 15 dBm to 5 dBm 2150 MHz to 2750 MHz: 13 dBm to 15 dBm 2750 MHz to 4000 MHz: 5 dBm to 0 dBm 4000 MHz to 6000 MHz

Hi - it's not clear what you by it doesn't have enough power. Since it worked on the Win10 machine, I going presume by "not enough power" you don't mean electrical power - you mean it's not as capable as you had hoped. In any case, I know nothing about Win10, but you need to figure out how many b

Re: [Hackrf-dev] Rx Performance new user

If you configure the HackRF with the same bandwidth and sampling rate as the RTL dongle - roughly 2.5 Mbytes/sec, you should find they perform the same below 1.2 GHz. In order to determine if you have enough CPU power to drive the HackRF at 10 Mbytes/sec or higher, type hackrf_transfer -r /dev
