« on: December 14, 2024, 0042 UTC »
0039z - Music. SIO 443. Peaking ~S8+ via Airspy HF+D and 31' vertical. DSB sync tuning. Some band noise and fades but copyable.
0043z - ID perhaps? Moderate to deep fade.
0044z - Music.
0048z - Liquid Radio ID.
0048z - Liquid Radio ID.
0055z - Music. SIO trending 444. Better SNR with my 30' inverted delta loop (without preamp for a change).
0058z - Liquid Radio ID.
0115z - Liquid Radio ID and liquidradioonline.com mention.

Thanks for the broadcast! :)

0029z - Waterfall carrier. Intermittent modulation. Airspy HF+D and 31' vertical.
0031z - Carrier disappeared. Likely OTA.

Nonetheless, thanks for the broadcast! :)

Equipment / Re: Best MWDX antenna?
« on: December 13, 2024, 2217 UTC »
Power company knocked out part of my local RFI. Lose clamp on a nearby pole. Waterfall looks better.

Changed preamp on the 148' LoG. Still not a great preamp, but it pulls me back into the top 30 SNR rankings for Kiwis, at least at night.

Using an active RF distributor to split the 148' LoG to my two online SDRs.

2026z - Moved to 6965am, likely due to intermittent UTE above.
2028z - Music. SIO 444. ~S8 peaks via Airspy HF+D and 30' inverted delta loop with preamp. DSB sync tuning. Some static crashing but otherwise a decent to good copy with some noise filtering applied here.
2036z - Music. SIO trending 443 at times but still copyable. The recently added ability to set IF/AF DSP noise filter bandwidths in SRSharp 1921 beta helps.
2038z - Sternradio ID.
2113z - Switched to ~6962.2am at some point. SIO 444. Peaking over 50dB SNR.
2141z - Sternradio ID and QSL info.
2156z - Music. SIO 443. Wide audio.
2203z - Signing off music. Band also seems to be improving here. SIO 545. Peaking over S9+10.
2306z - OTA.

Thanks for the broadcast! :)

0316z - Music. Closer to ~6849.92KHz, so likely Liquid Radio. SIO 433+. ~S8 via Airspy HF+D and 30' inverted delta loop. with preamp. DSB sync tuning. Some band noise but generally copyable.
0322z - Liquid Radio ID into music.
0327z - Liquid Radio ID into music.
0353Z - Music. SIO 333+. ~S5 via KiwisDR 2 and 148' LoG. AM sync tuning and some noise filtering. Some fades but listenable.
0356z - Liquid Radio ID into RoboCop ED-209 clip.
0359z - Music.

The forum crashed last night, but IIRC, the broadcast continued to sometime after 0500z.

Thanks for the broadcast! :)

Equipment / Re: Useful audio DSP gear? Could be. Taramps Pro 2.4D Dynamic Peak (audio DSP)
« on: December 04, 2024, 2146 UTC »
Basically a multi-channel equalizer and limiter, though no noise filtering is noted.

BHI does have a parametric equalizer, but otherwise most of its product line is known for the company's digital noise filtering routine(s).


I have not used BHI noise filtering, but I do have a couple of now ancient Timewave DSP-9 noise filters. They are decent for narrow CW filtering and filtering, plus cleaning up some of the background noise in casual SSB voice listening.

With SDRs these days I like SDRSharp for its integrated IF, audio, etc. digital noise filters. Otherwise I sometimes pipe audio through EasyEffects to use RNNoise and/or DeepFilterNet algorithms. StereoTool's dehummer and noise gate filters can also help cleanup background band noise.
