It's visual and all math. A higher FFT value also requires higher processing power

What is your location?
What is in your surrounding area? Solar panels? LED lights for the streets?

That looks like power line noise to me. How high up the band is the noise?
Did you put a rotor on the loop? How is it pointed?

It takes very little RF to blow the front end of the RSP. You need at least 5-10w minimum either dead key or a CW carrier to engage the LDG tuner properly. I suggest a manual tuner if your want to zero in on signals with the RSP. You can find them used at Ham fest for $30 or online from $30-50. If y...

P4 with two gigs of ram should be ok to run HDSDR. I don't think you will be able to process a full 8 gig of bandwidth. You would want to run the zero if mode at 1.5 with a bandwidth of 2 megs If it starts to stutter in audio dropouts go into low If Mode and lower the bandwidth further Good luck Mike

With your setup and antennas i would recommend the following setting in the EXT/IO Turn off the AGC Ride your gain control in the 60 (high)- 70 (low) per conditions per band. Usually 65-60 is the sweet spot. Later i will post a my complete tutorial on optimizing the SDRPLAY with HDSDR. All the best ...

Just my 2 cents. You might want to invest in a par HPF and or a FM Notch (fm trap) it will solve most if not all of you image/intermod issues. I use both and have not had any issues since... You can get a radio shack fm trap on ebay for $3.00-$5.00 if one does not work then run 2 of them back to bac...

The ext/io is for hdsdr and sdr# and any other front end that supports the ext/io. Sdr-console does not use this
