The power supply most likely, especially if you use a switching supply.

They are high amplitude and periodic (every 1000 Hz)

I agree, no signals to decode.

But at some point it decoded something; as you have a callsign & distance below the frequency.

Do you have an antenna switch? Maybe set to the ground position?
Bad coax?
Acts like no antenna is connected.

No decoding because of strength of vertical spikes every 1000 hz.
