Re: [Hackrf-dev] release 2017.02.1

I have a dual boot computer (Windows and Ubuntu). So, I could use the Ubuntu system to update the firmware, but would I need to update hackrf host on both OS? If yes, then I would like to hear from anyone who has actually built the latest hackrf host tools on Windows. The instructions on the

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

Yesterday (thanks to help here on this mail list) I got my hackrf One working as an FM receiver. I have SDR# v1.0.0.1483 running on Windows 10. So, today I want to move on to narrowband fm. I picked APRS channel because there is steady traffic. I tuned SDR# to 144.39 MHz, NFM, bandwidth 8k, LNA

[Hackrf-dev] How to verify hackrf is working

I have a new hackrf One and I can't get anything out of it. I am running Windows 10 (64 bit). I have it plugged into a USB port, it shows up in Device Manager. I ran the Zadig program to set the driver to WinUSB. I can see the device with hackrf_info, as follows:

Re: [Hackrf-dev] FATAL: No supported devices found to pick from.

I tried to run my hackrf in a VM and it almost worked. For the Osmocom source block, I had to specify the hackrf by serial # on the device options. I got it to recognize the hackrf and it would appear to function for a while, but the virtual usb driver would randomly fail without any error

Re: [Hackrf-dev] Is my new (old) HackRF Deaf?

Jerry, Learning how to use Ubuntu, and Gnu, and HackRF is a challenge! I went down that path about a year ago. The issue you describe hits every new user. When you are running GNU radio, you have to turn up the IF gain to about 40 - it defaults to 0. Also, turn up the BaseBand gain to about

[Hackrf-dev] Still hoping for PTT

Has there been any progress on implementing digital i/o from/to the hackrf One. I'm hoping that someday the hackrf can supply a PTT signal to an external amplifier. Jake ___ HackRF-dev mailing list HackRF-dev@greatscottgadgets.com

Re: [Hackrf-dev] RX/TX switching

Matteo, Using GnuRadioCompanion, there is a way to switch from RX to TX, but it is not obvious. If you use the Osmosdr Source and Sink blocks, and specify the hackrf as the device, then one works but not the other. However, if you use the Osmosdr Source and Sink blocks, and specify Soapy as the

Re: [Hackrf-dev] HackRF and Spyverter

Alejandro, The Spyverter will shift the 457kHz signal up by 120 MHz, so the result will be 120.457 MHz. Connect your 457kHz signal to the input of the Spyverter; connect the output of the Spyverter to the rf input of the hackrf. Remember to apply 5Vdc to the Spyverter (make sure you use a

[Hackrf-dev] Hackrf One output impedance

What is the output impedance when transmitting at 147.42 MHz with and without the output amplifier? I’ve built an RF amplifier to boost the output about 26 dB, but with no signal it oscillates. The data sheet suggests it is probably due to an impedance mismatch between the Hackrf and the amp.

Re: [Hackrf-dev] How to tell if antenna is faulty

Cliff, I have a hackrf and an Ant500. With the antenna fully extended, you should measure a very low resistance between the tip of the antenna and the center pin of the connector. Mine was about 2 ohms. If you have 75 ohms, then there is a problem. Try again between the center pin and the elbow
