Hi All, I finally have my SDRplay RSPdx working: I now see why it's
critical to have a spectrum display to start the RFI remediation process!
I haven't turned off the house power yet but that will come soon.
Initial findings:
- I have 10-15 dB spikes every 58 kHz (not 60). I see this on 80 to 10m (I
don't have antennas for higher frequencies). On 160 the spikes are about
every 43-44 kHz. Suggestions on the most likely offenders? I assume HVAC
systems?
- I previously reported no RFI from my shack-installed Utilitech 1500765
recessed LED can/puck lights. I take that back! On my 10/15/20m resonant
antennas (which I recently put up), the shack lights raise the noise floor
by 7 dB on 10 and 15. I see 3 dB on 12 and 17m using non-resonant
antennas. Nothing on 20m or lower.
- recent rains have suppressed the power line buzz from S3-5 to lightly
heard (which may have allowed me to see the above problems)
73, Kenny K2KW
