RTL-SDR Blog v4 Dongle is Sensitive on HF

Hearing signals at no rf gain and no agc's enabled. Does not take much gain to reach a listenable level.

Thanks for this. Sensitivity is the datum I've seen cited only very, very rarely!

What antenna were you using?

homebrew center fed dipole cut for 27MHz

I have just bought RTL SDR v 4 . What is the simplest antenna that can be used to receive airband/vhf/uhf /shortwave and ham bands?

[@sunplio]

long wire with an alligator clip clipped to telescoping antenna. speaker wire works. 30ft of wire is fine.

@@sunplio which all bands will it cover?
