Question #1
A fellow ham( VE4GH ) has an IC-751 which he uses with CT. It seems that when
he uses CT for CW contests, the rig switches to CW mode and mutes. Obviously,
the program has switched the rig into CW mode and is looking for a specific
filter. I believe he has a 500 hz filter installed. Can someone in the CT
bunch tell me exactly what Icom filter the program switches for ?
Question #2
VE4GH also likes to run " QRP assisted" category in contests. Since our
cluster in Winnipeg is stand alone and has no input from remote areas,
spots are few and far between. Is QRP category all lumped together ?
I've never seen a "QRP ASSISTED" class in any of the contests.
Is there such an animal. If not, and single op QRPers who use cluster
spots are placed in the "SO Assisted category" , what's the point in
running QRP ??
Any comments/ Suggestions appreciated. Thanks
Rob VE4GV

Lost few hours because of equipment problems. Working japanese in the

I think the 10-minute rule is easiest to interpret and apply if one thinks of
each
QSO as a "toggle". No band changes are required until an event occurs on
the new band. Then, and only then, does the 10-minute clock begin to run.
Toggle #1 says that to be "on" a band, a QSO has to be _completed_. What
happens when the mult station is calling away like mad for many minutes
prior to making that QSO (or maybe never makes it) while the run station
continues to make contacts? Clearly, two transmitters were on the air at
the same time, but only ONE was making QSOs. The log looks no different
than if only one station is transmitting. But if the QSO is made, then
the 10-minute toggle is invoked and operation must remain on the new band.
Toggle #2 says that _any_ transmission on the new band, even "QRL?" in
the strictest sense, starts the 10-minute clock. That means that a
conscious choice to work that new mult has to be made, requiring a band
change. I would then expect the run station to move to the _same_ band
and begin calling CQ, synchronized with the mult station's pauses between
calls and shutting down while the mult station QSO is made. This, too,
satisfies the letter of the rule.
I think both toggles are clear and have a simply stated invoking condition. I
would vote for Toggle #2 as my preferred interpretation.

Eric's mail points out two serious problems with understanding and
interpretation of the multi-single rules. Wish the contest sponsors
would publish some clarification on this.

We used to assume that the 10 minute period started when the QSO was
made. This is the best way to prevent a 10 minute rule violation.
However, most people just look for a 10 minute window around the QSO.
This is the best way with regard to maximizing score.
The way the rule is written, the 10 minute window is OK.

I agree. There is nothing that says you have to be off a band for 10
minutes. Only that you may work multipliers on a second band during a 10
minute period.

I am not on the committee but it's my opinion. Multi-single is a really
great category that leaves plenty of room for interpretation. There is
no rule which simply states only one transmitter may be on the air at one
time!!!
I have been at M/S efforts where 4 people are talking at the
same time and we are not in violation of the rules. Just a rule calling
for only one transmitted signal, coupled with the 10 min multiplier rule,
would "equalize" all the various M/S efforts a lot.
