Longwave Loggings / Medi 1 171 AM 0132 UTC 1 FEB 2024
« on: February 01, 2024, 0137 UTC »
Music at 0132z. SINPO 35443. ~S6 via Airspy HF+D and 31' vertical. DSB sync tuning. Some static crashing, but listenable copy.

Verified against online stream.

FM DX Loggings / FM DX Propagation 31 JAN 2023
« on: February 01, 2024, 0022 UTC »
I am not an active FM DXer, and it was only a relatively short hop, but around 12:00AM EDT earlier today I noted an occurrence of FM BCB propagation

WCFB Deland on 94.5 at ~80 miles away was knocked out temporarily by WARO Fort Myers at ~300 miles away. Lasted several minutes.

The tropospheric ducting forecast for 1/30/2024 predicted marginal to fair conditions for propagation along Florida's west coast.

BTW, it certainly was not the antenna. ;) I have one of those small inexpensive Bingfu dipoles vertically oriented in a window for local FM BCB. At 10" wide it likely would be much better suited for UHF. Anyway, it was padding for free shipping of an Amazon order, and it looks slightly better than the two wires I had there previously.

Music at 2342z. SINPO 55343. ~S9 via MSI SDR and 18' end-fed vertical. AM sync tuning. A little noisy, but a listenable copy.

10/11 meters / Re: 11m Band Activity 30 JAN 2024
« on: January 31, 2024, 2324 UTC »
No video or recording. These posts with SDR screenshots are mostly just an occasional quick glance at 11m activity from my QTH's perspective. 11m DX has been quite actove in recent weeks.

I used to somewhat more actively log and detail upper-HF activity with frequencies, mode, times, regions, etc. Not so much these days.

I can note R4002 does a nice jog logging 11m digital, pagers, etc. :)

SDR - Software Defined Radio / Re: Recommended Linux distros, for SDR. Overall Linux OS for communications
« on: January 31, 2024, 2146 UTC »
If you package SoapySDR support, you might want to look at libmirisdr and SoapyMiri for SDRPlay devices. They are open source alternatives to the proprietary API. :)

https://github.com/ericek111/libmirisdr-5
https://github.com/ericek111/SoapyMiri

I use them with SDRAngel and Gqrx for a couple of inexpensive Mirics-chipset SDRs. AFAIK, they should work for SDR++ as well.

SDR - Software Defined Radio / Re: SDRPlay RSP1B
« on: January 31, 2024, 2134 UTC »
I started down the SDR rabbit hole with RTL-SDR and Airspy products, so I am usually more at home with SDRSharp on Windows and SDRangel on Linux.

My potential interest in SDRConnect is primarily because it is a native Linux app. I am focusing more on receiving and getting a KiwiSDR 2 running (hopefully) in the near future, but I will keep the RSP1B in mind for afterwards.

BTW, checked the SDRuno release notes. Only note is adding RSP1B support.

Moderate 11m DX activity at ~1730z. Columbia, South America op working DX on 27365lsb. MSI SDR and 18' end-fed vertical.

1242z - 26585am - Spanish language ops over music.
2244z - 27385lsb - Australian DX noted.

More specs:

Launch video:

Low frequency noise appears considerably improved:

I might have to order one for further evaluation.

Anyone using SDRconnect? If so, feedback?

SDR - Software Defined Radio / Re: SDR++
« on: January 31, 2024, 1644 UTC »
I get the feeling, though I suspect all you really need to do is install SoapySDR. :)

That would mean getting SoapySDR installed on your system if not already deployed. There appears to be Homebrew scripts for MacOS here:

https://github.com/pothosware/homebrew-pothos?tab=readme-ov-file
https://github.com/pothosware/homebrew-pothos/wiki

Since it is part of the source tree, the SDR++ binary build should already have the needed support to interface with the required SoapySDR module.

Equipment / Re: Best MWDX antenna?
« on: January 31, 2024, 1635 UTC »
Need to check the 31' vertical. Signals are way down. Suppose I will start with inside jumpers and work my way from there. Fun stuff.


Resolved. Appears to either have been the jumper to the KD9SV common-mode choke right outside the house, or it could be the choke itself. I just removed them on both my 31' and 148' loop-on-ground for now.

I probably should replace the chokes with galvanically isolated chokes anyway.


Seller cancelled the 5v power supply order. Oh well.

Ordered a Lambda LCS-CC-5-O with a LHOV-5 over-voltage protector installed. It is way oversized for my purposes at up to 16A capacity, but it was decently priced.

The 11m band is hopping this morning, UK traffic and usual DX on 27385lsb. Noted 27.78125nfm (UK CB ch19) traffic.

MSI SDR and 18' end-fed vertical.

« on: January 30, 2024, 0109 UTC »
Waterfall carrier and hints of intermittent modulation at 0108z. Airspy HF+D and 31' vertical. It is there, but it is not copyable at the moment.

Nonetheless, thanks for the broadcast! :)


Faint modulation heard at 0118z via Northern Utah WebSDR Server #3.

10/11 meters / Re: 11m Band Activity 29 JAN 2024
« on: January 30, 2024, 0106 UTC »
Sure enough, 11m DX was rolling much of the day when I occasionally checked. :)

0056z - 27385l - 11m propagation is going weak signal here, but Australia/NZ and potentially European DX noted. Airspy HF+D and 31' vertical.

« on: January 29, 2024, 2340 UTC »
2329z - Radio play or skit. SINPO 35433 via Airsphy HF+D and 148' loop-on-ground. Generally copyable but the audio seems quite dynamically compressed, or I suppose it could be the accents, too. Moderate fading.
2341z - Mention of being produced for the BBC.
2343z - Reference to "August 4, 2026."
2347z - Dropped a search and verified dialog against "There Will Come Soft Rains" by Ray Bradbury (thanks Ct Yankee)
2348z - Off air

Thanks for the broadcast! :)
