the expense and trouble of putting up two stacked yagi's instead of just
one. FM costs 3 dB or more in S/N over SSB, and vertical polarization cost
another 3 dB in S/N over horizontal polarization, so it is not too long

phone, but using DominoEx, the retransmission is very fast (70 or 100 wpm)

20 wpm. This way, nobody gets left out, and there is a minimum of dead air

If you are not an ARRL member, a description of the interface described
on page 30 of the June QST is here:

In my reply, IC-2000H should have read IC-2200H.

Andy,
Try running a NBEMS Puppy Linux CD live. You can access all the data and
windows partitions with Puppy from the Puppy Desktop.

The latest Puppy Linux is here:
http://puppylinux.org/downloads/official-releases/latest-production-version
(not the NBEMS version, but will work). You just need a computer to
access the Internet and a program that will burn an ISO.

Rodney,
The same interface you use for PSK31 will work. NBEMS is a software
suite. Go to www.w1hkj.com/NBEMS and download the software for your
windows or Linux version.

John,
You might consider NBEMS for HF: www.w1hkj.com/NBEMS. We have optimized
the DominoEx and MFSK16 modes for high static conditions and also have a
verification program called Wrap if you do not want to use flarq.

EMS and so does Multipsk and
PSKmail. You can use either of those if fldigi or NBEMS do not do what
you need.

gnal. Even when using
MT63-1000, a center frequency of 1500 Hz might be a problem on some rigs
with narrow IF filters.
