I am working on plans for a single op contest station, and need some input on
how you guys key two seperate rigs from one headset. I will have one run
radio, and then I will have a multiplier radio. Just curious as to how that
is done with maximum effiency. Please reply direct and I will summarize
replies if there is interest. Thanks in advance.

I asked the same question about a year ago. The summary of the data I
collected is available on KA9FOX's web site.

Subject: More on MFJ 432 voice keyer
Message-ID: <199602262211.RAA19376 at borg.mindspring.com>
I got MFJ to FAX me a schematic and spent about 30 minutes on the phone with
them and we got nowhere. I can hook my foot switch up to the PTT and PTT
ground but its just like keying my MOX switch on the Yaesu...still no mic
audio gets thru.
Short of sending it back or setting it up so the keyer and the mic are on
two lines to the Yaesu has anyone made this work with a Yaesu? Mine is a
FT-980, but FT1000, FT990, FT767 are all the same. I am using the Heil
BM-10 with Heil wired 8 pin connector (only the mic is wired). I can attach
a foot switch for PTT. The MFJ help line personnel said something about
providing a voltage to key the IC...I though only ICOM had that requirement.
I can record into the memory and then that keys the Yaesu...sure wish I had
a clear diagram and theory of operation.

Islands on the Air Contest Rules 1996
1. General. The aim of the contest is to promote contacts between
stations in qualifying IOTA island groups and the rest of the world
and to encourage expeditions to IOTA islands. Please note the changes
to rules 4(a) to 4(c).
2. When. 1200 UTC Saturday 27th July to 1200 UTC Sunday 28th July
1996.
3. Bands and Modes. 3.5, 7, 14, 21 and 28MHz, CW and SSB. IARU
bandplans should be observed, with CW contacts being made only in the
recognised CW ends of the bands. Contest preferred segments should
also be observed, i.e. no operation taking place on 3.56-3.6MHz,
3.65-3.7MHz, 14.06-14.125 and 14.3-14.35MHz.
4. Categories. (a) Single operator. Only one transmitted signal. Use
of packet cluster or other assistance during the contest places the
entrant in the multi operator category. CW only, SSB only or
mixed-mode. (b) Single operator limited. CW only, SSB only or
mixed-mode. Operation is limited to 12 hours. Off periods must be
clearly marked and must be a minimum of 60 minutes in length. (c)
Multi operator single transmitter, mixed mode. The use of one "run"
transceiver and one "multiplier" transceiver is permitted. NB This
category is open to Island Stations only.
5. Sections. (a) IOTA Island Stations Stations on an island with an
IOTA reference, for example AS-007, EU-005. This section includes the
British Isles. Note: mainland G/GM/GW = EU-005, mainland GI/EI =
EU-115. Entrants intending to operate from a location whose IOTA
status is not clear are advised to confirm validity by reference to
the IOTA directory available from RSGB headquarters. Please indicate
on the entry whether the station is permanent or a contest DXpedition,
i.e. antennas and equipment installed specifically for the contest.
(b) World (listed by continent) Any station in a location which does
not have an IOTA reference. (c) Short Wave Listener See rule 10. The
format of the listings will depend on the number of entries received.
6. Exchange. Send RS(T) and serial number starting from 001, plus
IOTA reference number if applicable. Do not use separate numbering
systems for CW and SSB. Stations may be contacted on both CW and SSB
on each band. Entrants in section (a) MUST send their IOTA reference
as part of each contact.
7. Scoring. (a) QSO Points Each contact with an IOTA island counts 15
points. Other contacts count 5 points, except contacts with the
entrant's own country or own IOTA reference, which count 2 points. (b)
Multiplier The multiplier is the total of different IOTA references
contacted on each band on CW, plus the total of different IOTA
references contacted on each band on SSB. (c) Total Score The score is
the total of QSO points on all bands added together, multiplied by the
total of multipliers.
8. Logs. Entries are preferred on disk using recognised contest
software i.e. SD, CT, NA but must be accompanied by a summary and
signed declaration that the rules and licence conditions have been
complied with. Separate log sheets must be used for each band (but not
each mode). Paper logs are also acceptable. Single mode entrants who
make contacts on the other mode should submit these separately as
checklogs.
Logs must show: Time, Callsign, RST/serial number/IOTA reference sent,
RST/serial number/IOTA reference received, multiplier claimed, and QSO
points. Entrants are encouraged to submit cross-check ("dupe") sheets
and a multiplier list. Entries must be postmarked 31st August at the
latest, and mailed to the following address: RSGB IOTA Contest, c/o S.
Knowles G3UFY, 77 Bensham Manor Road, Thornton Heath, Surrey, CR7 7AF,
England. IOTA stations must state their location, i.e. island from
where they operated, as well as their IOTA reference number. Checklogs
from non-entrants are welcome.
9. Penalties. Points may be deducted, or entrants disqualified, for
violation of the rules or the spirit of the contest. This includes
refusal by IOTA island stations to make contacts with their own
country when requested. Use of a third party to make contacts on a
list or net is also against the spirit and may lead to
disqualification. Duplicate contacts must be marked as such with no
points claimed. Unmarked duplicates will be penalised at ten times the
claimed points, and excessive duplicates may cause disqualification.
10. SWL Contest. Scoring is as for the transmitting contest. Logs
must be separate for each band, and show Time, Callsign of station
heard, RST/serial number/IOTA reference sent, callsign of station
being worked, multiplier claimed, and QSO points. Under "callsign of
station being worked", there must be at least two other QSOs before a
callsign is repeated, or else ten minutes must have elapsed. If both
sides of a QSO can be heard, they can be logged separately for points
if appropriate.
11. Awards (a) Certificates will be awarded to leading stations in
each category and section, and in each continent, according to entry.
(b) The CDXC Geoff Watts Memorial Trophy (Non returnable) will be
presented to the entrant whether single operator or a multi operator
group in the IOTA Islands stations section (Non DXpedition subsection)
with the overall highest score regardless of mode. (c) The IOTA Trophy
(non-returnable) will be presented by the IOTA Committee to the
entrant, whether single-operator or a multi-operator group in the IOTA
Island Stations Section (DXpedition subsection), with the overall
highest score, regardless of mode. A trophy will also be awarded to
the leading non-DXpedition IOTA entrant. (d) The DX News Sheet Trophy
(retained for one year) will be presented to the British entrant
operating from a location in the UK (including GD, GJ and GU) with the
highest checked score in the single operator SSB category, (Category
A). The winner of the IOTA Trophy will not be eligible for this award.
(e) The David King G3PFS Trophy, In Memory of Geoff Watts, (retained
for one year) will be presented to the British entrant operating from
a location in the UK (including GD, GJ and GU) with the highest
checked score in the single operator SSB category, (Category B). The
winner of the IOTA Trophy will not be eligible for this award.
12. Note from the IOTA Director. Amateurs planning to activate an
all-time new one for IOTA over the IOTA Contest weekend should, if
possible, arrange to commence their operation in the preceding 24
hours to enable the new reference number to be issued before the start
of the contest. Once the contest is under way, it will not be possible
to issue a new number and, without this, contacts made will not count
as island contacts.

Hello Mario. I believe I read something about your CW decoder in the NCJ
some time ago. Last year I wrote one myself for the PC. It was to be a TSR
you loaded before running CT. You pipe receive audio to it via your sound
card. The program would listen to a CW pileup, pull out multiple callsigns,
and display them in a little pop-up window on the CT screen. The idea was
to recover weak callers (multipliers!) that were aurally masked by louder
signals.
I got part of the system running (the FFT that generated parallel CW streams
and the correlator that decoded them). Technically it was great fun,
especially the correlator (I didn't bother to decode dots and dashes--I went
after whole characters). But after I got the basic algorithm working and
printing pileup callsigns on my screen, I realized that I would not want to
use this device in a contest myself! I love CW and I love digging calls out
of pileups. To me, that's a big part of the fun of operating. My decoder
wasn't perfect but it certainly would increase your score. Therefore, a
serious competitor would feel compelled to use one whether he wanted to or
not, whether it made the contest more fun for him or not. I thought this
was an awful position to put someone in.
Logging programs make contesting more fun by eliminating the tedious work.
They free you for the enjoyable parts--like digging callsigns out of
pileups! For me, automatic CW detection steps across the line and takes some
of the essential fun away. It's like hiring someone to have sex for
you--sure, it saves time and gets the job done, but is that what you really
want?
I think it might be fun some day to have a contest pitting program against
program (like computer chess matches). In fact, I'm sure this is coming.
It might also be fun to have a variant of SOA that involves what amounts to
artificial intelligence. But for me, there's definitely a point where I
want the machinery to stop.
My product was going to be called PileUp Buster 1.0. Maybe some day I'll
resurrect it. After some soul searching, I decided to take the technology
and apply it to RTTY where human decoding wasn't involved and it wouldn't
take away any fun.
73--Brian, K6STI
