Signalink is not capable of high speed ARQ.
It uses vox, and doesn't have a real PTT with RTS.

at the ppm issues
with modes such as MFSK, even a few Hz is a problem.
Generally, not on HF so much, as transceivers tend to have less drift on HF,
especially on 80m and 40m, but definitely on VHF, where excessive drift can
often be a serious problem for some digital modes.

.
The popular IC-746Pro, for example, drifts 100 Hz between receiving and
start of transmitting, unless a TCXO is added, causing the loss of the first
few characters or words on PSK63, so I have switched our 2 meter digital net
from PSK63 to DominoEx.

Neil,
QuikPSK (http://www.qsl.net/kh6ty/psk63/) can send a picture of your ugly
face, even if you do not have an Internet connection. It is not very big,
but big enough to see how ugly you look! ;-)

and data on the same frequency.
In addition, although we are improving NBEMS support on HF with a new
static-robust mode (soon to be released), 2 meters is still the band of
choice for fastest transfers and dependable point-to-point circuits.

, around 1500 Hz tone
frequency, so that is probably what you heard, since you are close by. The new
mode is called DEX and is expected to be released for NBEMS HF beta testing
with this group in about two weeks.
