These can’t be connected a reciever. They are inductively coupled. There
are construction articles for these online. I’ve copied Gary, the creator
of these so maybe he can link to the construction articles.

Hi Paul,
I know they are not commercially available. I am interested in building one
myself. All the Youtube videos I have watched (about 15 of them) don't show
any significant construction details. I am wondering if they can be made to
work in the 137, 183 and 475 kHz ham bands and the LF NDB bands. And the
videos I've seen show an FSL antenna that is just one coil with coupling to
an AM receiver accomplished by proximity. How would I connect one to an SDR
receiver that covers this LF range? Zack W9SZ On Fri, Jan 28, 2022 at 11:37 AM Paul B. Walker, Jr. <

USA ... near-freezing conditions in Florida US state.Thanks Roger and Jeff, yes, normaly align remoted SDR units
for fq measurement reason by
WWV, WWVH, WBCQ 9330, exact frequency access or various WRMI 5800, 5850, 5950, 9955, 15770 etc. etc. too and had noticed this morning, around 08 UTC time,
that all WRMI Okeechobee outlets ... had left the air. CUBA RHC Bauta in English checked today Sunday Jan 30 at 07.26 UT, 6060even kHz exact fq, and much clean audio,
no buzz at all today to state,
S=9 noted in eastern states like NY, NJ, MA, also at 9699.996 kHz channel in 31 meterband, also from Bauta site
(ex6145/6165 kHz in B20 season), much clean audio too at 07.28 UT. But on western US tate parts CA / WA, or Alberta-CAN, Masset BC-CAN
the Cuban and Florida signals much poor and tiny this Sunday,
only S=3 to S=6.
The antenna in Masset BC province pointed to East Asia ?
The Japanese Nikkei R1 Nagara signal on 6055 kHz arrived
with S=9+15dB instead, path over Alaska and the Pacific at 07.40 UT.
When tuned-in and checked again both RHCuba Bauta signals at about
08.18 UT, heard RHC in Esperanto language in progress,
the half hour program only on Sundays at 08.00 and 08.30 UT,
S=9+10dB again noted in Rochester, NY state, and
9699.996 kHz - Bauta in 31 mb - same strength too - and
surprise, surprise
an extra treat for the North America and Europe listener
of the Bauta transmissions:
empty signal carriers appeared still on air on both 6060 and 9700v,
between 08.30 UT - and 22 minutes longer, until switch-off exact
at 08.52:30 UTmuch late - ended the sleep of the RadioCuba local Bauta technician. [selected SDR options, span 12.5 kHz RBW 15.3 Hertz]

Power is out at WRMI! At approximately 0745 UTC Sunday 30 January, we
lost all electrical power at the WRMI transmitter site in Okeechobee,
Florida. This is the reason that all transmitters and our Internet
stream are off the air. Florida Power & Light is dispatching a team to
our site to try to restore power as soon as possible. The power outage is caused by the near-freezing conditions at our site
tonight, which is a very unusual situation here in South Central Florida. https://downdetector.com/status/fpl/map/ Most reported locations : Miami,
Tampa, Orlando, Fort Lauderdale, North Port, Naples, Atlanta, Margate, Fort
