New user having problems - can't hear!
Posted: Sun Nov 13, 2016 10:55 pm
Hello,
I just received a brand new SDRplay RSP1 from HRO. I am in Hawaii.
I have been able to set up CubicSDR on my iMac, and SDRuno on Windows 10. I can connect to the RSP and change settings. I have tried several antennas: a 1m long wire; a 3m long wire; a 10m long wire. I am using a SMA to SO239 jumper about 30cm long.
However, I can't seem to hear anything except 2 FM stations (Hawaii Public Radio 89.1 and 91.3 MHz) which are about 10 km distant. I hear them poorly, even though they are full quieting on my analog receiver. I was barely able to hear a National Weather Service station on 162.550 MHz which is strong on my portable NWS receiver.
I have not been able to hear anything on MW, SW, Ham bands (80m, 40m, 20m, 15m, 2m, 70cm), or other VHF/UHF. I have fussed for hours with the NLA on/off and Mixer Gain controls. I can not find ANY combination which provides a low noise floor with any signals. I have tried FM, NBFM, AM, USB, LSB, etc. I did see some spurs from a digital audio amplifier in the shack, but those went away when I turned it off. My iMac (2015) is RF quiet.
I am in perhaps the most radio quiet place that you can be. In fact we cannot pick up any local AM radio or any TV signals here - because there are none. I can only hear the two HPR FM stations mentioned above on the FM band. However, I can hear tons of HF (Ham and SW) and 2m and 70cm ham here with analog transceivers.
I am an extra class hame - AC7N, with 50+ years of radio experience. Why can't I hear ANYTHING?
Mahalo.
Aloha,
Pascal
