Xiaohu3389 I would like to buy a device that can be used for direction finding (in conjunction with a logarithmic spiral antenna) for things like directional radio or shortwave broadcasting.
BG5JOK This directional finding isn't very good. Once the temperature frequency deviation exceeds these indicators, it starts to rise. Also, when using the SDR++ on a mobile device, the C to A adapter is relatively easy to loosen and not very stable.
Xiaohu3389 BG5JOK Okay, I'm ready to buy a field strength meter that was previously used with an old TV.
BG5JOK Xiaohu3389 I'd like to take a look at the waveform and see how it performs. If I really need to measure in the field, should I get something like Tiny SA instead?
