[Hackrf-dev] Low signal on my HackRF One with ANT500

[Doug Theriault]

Matt,

You might want to check whether your ANT500 is measuring a short at the connector.  Another user had issue where the spring/coil was shorting or not making proper contact with the center conductor of connector.

I have an old Nokia N900 with an FM transmitter that I've fired up on 95.0MHz. I'm able to receive the transmission from that but the sound output from my speakers sounds like a typical very bad FM reception.
