Our "hidden message" last week in the PSK125R mode was not as successful as the
BPSK63F two weeks previously. Because the PSK125R is a wider mode, I had to put
it as low as possible to prevent it from being audible. This put the lower part
of the PSK125R right up against the carrier, and too low for many receivers to
process. This week our hidden message will be in QPSK63, a narrower mode,
centered on 65 Hz. It begins 21 seconds after the closing MFSK32 ends (29:06
into the half hour broadcast), mixed with the closing music. There is an RSID
but, as usual, it probably won't work. To my ear, at least, the QPSK63 is
This weekend's show is in the usual MFSK32 and MFSK64, with
ten MFSK images, And the silent QPSK63 at the end.

EDT) on 9925 kHz, via Germany. A minute of MFSK is at about 0130 UTC.

“This is a Music
Show” is the newest addition to digital modes via analog shortwave.
Most of the show is a music show, but the host transmits some MFSK text and
image near the end of the broadcast. It’s transmitted on WRMI Florida, Thursday
0100-0200 UTC on 5850 kHz, and Thursday 0130-0200 UTC on 9395 kHz (these are
Wednesday evening in the Americas). Also look for a waterfall ID at the
beginning of the show. email@example.com .

New York and Pennsylvania NBEMS nets.
Most weekends, as KD9XB, I check in to the New York NBEMS (Narrow Band Emergency
Messaging Software) net Saturday at 1200 UTC on 3584 kHz USB, and the
Pennsylvania NBEMS net Sunday at 1200 UTC on 3583 kHz USB (with out-of-state
check-ins now starting at 1130 UTC). Check-ins are usually in Thor 22, and
messages are in MFSK32 (PA NBEMS is experimenting with Thor 50x1 for messages).
Messages generally use the Flmsg add-on to Fldigi. If you are a radio
amateur in eastern North America, feel free to check in. Outside the region, use
an SDR in the eastern USA to tune in and decode. You do not need Flmsg to check
in, and most of the messages can be read without Flmsg. If you can decode the
net, send me an email to firstname.lastname@example.org , or tweet to @SWRadiogram , and
I will let them know you are tuned in. USEast NBEMS Net: Please
also note the USEast NBEMS Net, Wednesdays at 2300 UTC (7 pm EDT) on 3536 kHz
USB. I will try to check in to this net more frequently.
