[Hackrf-dev] lowest possible sampling rate

[Cinaed Simson]

Hi - what's the lowest possible transmit sampling rate for HackRF One?

I'm starting to play with a psk signal which has a modulator which
outputs 250 Hz.

Sampling in the MHz range is going to require a interpolation by the
resampler on the order of 5k.

It would be nice if I could reduce it by 3 orders magnitude.

I'm planning on using a rtl donle to receive the signal with a sampling
rate of 300k. I'm presuming it's valid sampling rate for the rtl dongle
since it's in the pull down menu of gqrx.

I believe some USRP's can go down as low as 250k.
