It's all about the Software

please have look at this picture...
for HF reception you should choose for Quadrature.

btw are you aware of these sliders? (hoover over them with your mouse)
(i don't have a antenna connected hense the spikes)

I have set the Quadrature in HF mode tuning but still, I can not receive any channel and I am hearing only noise.
Thanks so much for your help.

i'll be back...have to dig in my shack to find the same dongle back that you have.
I didn't use him for a long time cos the newer RTL v3 sticks are much better.

As far as my memory goes...i think you need the RTL v2 driver within SDRC but i'll test that.
You will NOT find this v2 anymore under Radio definitions, now we see only the latest RTL USB and TCP radio.

Thanks a lot for your time and your consideration.

Hi, i tested the same RTL radio that you have. It works nicely with the current RTL dongle support within SDRC.
Maybe a stupid question, did you connect the antenna to the HF port? otherwise i don't understand why you don't receive something on HF.
What is it doing on VHF/UHF?

I have connected the antenna to this port for AM690 and AM730

that's the correct port, please look at the connector....it has to be a MALE connector.
You will not be the first person who uses a cable with a female connector....

Yes exactly, It is Male connector.

Do you use a transmitter in the proximity of your sdr antenna?
What antenna do you use for the sdr box?
