PS: When using the ClassAxe Database if you don't know the call simply enter the frequency in khz in the freq field. It will list all NDB's using that frequency (and several Khz above the entered freq in ascending order)
Hi Paul: I am in the USA so I can't receive any ndb's from Europe. Here is the info I found on the Horta NDB.

Some of these RSP2pros had internally reversed A & B port connections. That is, the A input connector is internally connected to the B port and vice-versa. I have also noticed that strong signals can bleed over into the unused antenna input.
Have you tried putting the IFAGC into manual and reducing the slider to minimum (20db) and checking the effect? I have also noticed that some of the settings in SDRUno do not persist, they can change for unexplained reasons. I have seen this happen in the IFAGC setting when in manual mode.

glovisolL That's an interesting experiment you've done. Very helpful. I have a question. Any ideas why the noise floor is inversely proportional (more or less) to the RF gain setting? More RF gain lowers the noise floor. In my case it was varied from -116dbm at min RF gain to -135dbm at max RF gain....

A way to check this is to power down the 12 volt DC antenna supply w...
