*** REPLACE THIS LINE WITH YOUR MESSAGE ***
Aside from the pros and cons of japanese-made rigs (I have a Ten Tec Argonaut
and an old pair of heathkit Twins - the SB401/SB303), the inclusion
of aserial I/O port allows control of the rig from a remote. A recent
article in QST Magazine outlined a short BASIC program for doing this with
the new Yaesu FT757GX xcvr. (I've actually been toying with acquiring
one of these so I could rig it up with my Model 100 lap-portable).
The feature was written by Kjell Strom, SM6CPI and appears on page 38
of the October 1985 isse. The article also references the following publicat-
ions:

QST, July 1984, p.34, Low Cost Computer Control for the ICOM IC-720;
QST, August 1982, p.19, control of an ICOM IC-701;
QST, May 1981, p. 30, re IC-701;
The 1985 ARRL Handbook for The Radio Amateur, 62nd Edition, C. Hutchinson (ed),
ppgs. 19-24, Fig. 26;
and
Compute! Magazne, August 1982, J. Butterfield and J. Law, VIC Communications:
the RS-232 Interface, p. 99.

So there! I hope this is of interest and I would be quite interested in
learning how others are making out with similar systems of control.
My ideal system would allow the MiniMUF program to pre-set the rig at
the appointed hour for either AMTOR or packet transmissions with automated
message store/forward nodes! I'd also like to find out if anyone has
experienced any problems/solutions with emi/rfi while using these rigs
under program control.
