Dec 2022 Late spare parts item problem, of 60 Hertz and DRM mode ones ...:
But something is indeed happening. I'm flying to the USA tomorrow Dec 11
and will be at WMLK until Dec 22, to work off all the little unfinished
business
and do a DRM upgrade. <<<<<<<<<<<<<<<
The customer had ordered this later, but due to delivery problems
with the equipment I could not finish it in the summer.
Now all parts should be delivered.
In my spare time and maybe the side, I will also be active as ham
radio operator KT3Q partly with the WMLK antenna the KW stations.

USA   Re:  WMLK in DRM 9275 kHz
Surprise: WMLK in DRM 9270-9275-9280 at 1554 tune-in, usual gospel huxter
pontificating about what is adultery and what not, some dropouts, but
S=9+10dB into Maryland SDR. SNR 22v dB. I copy down all the other para-
meters. Label says it's the Ampegon TSW 2300 transmitter.
No spoken ID circa ToH. Presumably a test. FEBC finished with 9275 AM at
1600 UT, but this overlapped. Nominal WMLK-AM sked starts at 1700 UT.
At 1610 UT switched to Johnny Cash, "Ring of Fire", in a loop. Still past
1620 UT. At 1624 UT switched to other music with some dropouts: "Amazing
Grace" on plucked instrument.
Label says test from WMLK; antenna: curtain with double stacked dipole
xHE_AAC(A43456) WMLK EEP Audio 9.14 kbps.
When I first tuned in it was different: xHE_AAC(7B) WMLK Radio EEP Audio
7.46 kbps. SNR varying around 22 dB. Mode B, MSC 64 QAM, SDC 4 QAM
1627 text msg: Hello Nathaniel, how are you doing?
Parameters have changed again: 13.78 kbps, etc.

re Surprise: WMLK tests in DRM mode 9270-9275-9280 kHz at 1554 UT
earlier in December item in TopNews #1526 file of Dec 18, 2022,
Bodo DF8DX Ampegon Made in Switzerland technician wrote
USA WMLK Further transmitter work. The Engineer and his assistant have
returned to Bethel to resume work the WMLK Radio station. The picture
shows one of three rectifiers that change the voltage from AC to DC.
They will also be changing the frequency dynamics from 50 Hz to 60 Hz in
the rectifier firing control circuitry. See:
<wmlkradio.com/upgrade-to-the-rectifiers/>
The engineers that were with the unit before and after we bought this set
didn't think the frequency acceleration from 50 to 60 cps would make a
difference, but it has ! The European frequency is 50 Hz while the
US standard is 60 Hz.

Re: WMLK further work 2.0 WMLK site Dec 11 to 22.
Change from 50 to 60 Hertz Standard Mains Frequency, in North America
is 60 Hz 120 Volt.
It's a strange mail, I don't even know what it's supposed to tell me from
a technical point of view.
But something is indeed happening. I'm flying to the USA tomorrow Dec 11
and will be at WMLK until Dec 22, to work off all the little unfinished
business
and do a DRM upgrade. <<<<<<<<<<<<<<<

Re:  WMLK test in DRM mode on 9275 kHz. Some of the stuff displayed:
"Resistance to large delay/doppler spread"
DRM Mode D ILV L. I have no idea what a lot of this means.
"TX: Ampegon TSW-2500D from Ampegon Power Electronics AG, Switzerland"
Note: earlier it read TSW 2300 !  Which is it ??
1637 UT besides service 1 only, adds 2 and 4 but disappear before can
copy details.
SDR freezes 1640 UT, reload, a bit more, then WMLK signal off per S-meter,
blank DRM readout. 1642UT sig back but nothing heard - because it's now in
AM, starting regular sked early with Yahweh stuff.
Andrea Lawendel, Italy did not have enough to decode but heard via US
remote, same one? Wonders if illegally broadcasting to USA only ?
I think, no more so than all the other US SW stations AM with nominal
external targets.
DEJOM AM drops off AM air again at 1650 UT. 1651 UT back S9 with silent
DRM, 9.14 kbps. And so it goes.

Subject: [bdxc-news] WMLK on 15150WMLK (Assemblies of Yahweh) Bethel, Pennsylvania currently on 15150 khz
with a good signal here at 0830 tune in, usual preaching from the late
Jacob O Meyer. SIO 344.
First time I've heard WMLK on this frequency or at this time although
they have been registering the frequency for many years in the HFCC.
15150 was first reported by Glenn Hauser on 19 June.
WMLK schedule is Sunday to Friday: 0400-0900 on 15150, 1700-2200 on 9275.
