I didn't write the progrma, but probably because the data is not
coming in at a neat digital 300 bits per second. It is coming in as
audio tones mixed with noise, and probably needs ffts to extract the
data.

Not a lot of Amtor left so you may be hearing Pactor or Clover
signals.

YOu should be able to find some sound card programs to decode them and
you won't have to buy a seperate 'modem' for them.

You can use a sound card for RTTY, Amtor, and Pactor but I don't
believe you'll find sound card software for Clover or Pactor-II.

I tested HF multicast last year during a two week period, and posted the
transmit freq to both Packet and Internet. I never heard any interference,
and never received any reports of interference during those tests.
Another LandLine Lid mantra, "Hams are no good", tossed back into the
garbage heap it came from.

The destination in the second packet is "S9TW2S". Referring to the table
in the Mic-E spec, this decodes as follows:
ASCII Char: S 9 T W 2 S
Bit: A=0 B=1 C=0 N=0 L=1 W=0
Lat Digit: 3 9 4 7 2 3
The latitude digits match the first packet OK.
According to the spec, the A/B/C bits have to be inverted, so the
message code is 101 (i.e. a "Special" message -- I wonder if this is
correct?)
The N bit is 0, meaning South ........Hmmmm
The L bit is 1, meaning the longitude is greater than 100 degrees ...
Hmmmmmmmmmm
The W bit is 0, meaning East ....... Hmmmmmmmmmmmmmmmmm
Sooooooo, have I *still* got it all wrong, or are the headings on
columns 2 and 3 of the ASCII table transposed (i.e. col 2 is for Bit=1
and col 3 is for Bit=0), and should the message bits A/B/C really be
inverted?
Also, the table heading refers to "Message/N/W/L" bit settings, whereas
Fig 2 shows the octets in the order A/B/C/N/L/W -- i.e. the "W" and "L"
are transposed. Which is correct?
Looking at several other continental U.S. Mic-E stations just now, they
all appear to be South and East, which I'm disinclined to believe.
Comments anyone, please. I really need to understand this stuff.
