new rtl-sdr (RTL2832U) not hearing or seeing any ham radio on spectrum

Post by wulfe » Mon Jan 21, 2019 5:24 pm

I can not seam to get any ham reception on the spectrum. I can hear hear my repeater on my portable scanner. But not any on the computer. Is it that I just need to get a better ham antenna an plug it in. The one that came with it is picking up Noaa - am/fm radio an fire- police, but not any ham in the 2 an 70m range. Help

Hello:

Do you have the dipole antenna kit?

If so, can you receive broadcast FM? If you can you should be able to receive 2 meters. If you meant 70 cm instead of 70 meters the dipole kit will also work

Here is an info page https://www.rtl-sdr.com/using-our-new-d ... tenna-kit/

For 70 meters you will need a long wire or an antenna tuned for that wave length.

Hope this helps.
Robert

Can you listen to some FM stations? If so, then the hardware is functional.

What kind of antenna do you have for 70 m? The bundled antennas won't work too well close to the lower end of SW. Your portable scanner most likely have a ferrite antenna for that frequency.

If you meant 70 cm, try using an FM band-stop filter.

For 70m did you mean 70cm? If it's 70m you're after, i.e. HF, make sure to enable the direct sample mode, instructions at www.rtl-sdr.com/V3.
