Subject: SSB + Skimmer idea

Dear David,

Together with my friend, Yuri, UA3ATQ, we came up with an interesting idea
on how to identify SSB stations in contests using skimmer technology.

All of the elements are currently present out there and require no or
minimal modifications

1. Radios
2. Computers
3. Skimmers
4. Spotting networks

What needs to be modified would be logging software to enable additional
radio station identification.


The idea is to identify stations by transmitting CW ID at high rate of speed
(at maximum speed that skimmers can accept), at intervals that would be
determined by the operator's behaviour (CQing vs. searching).
CW ID should not be set to tax outside ops' hearing and would be for
skimmers only (although I would not exclude humans entirely).

Logging program would send an ID based on what the op is doing.

There is some trial and error needed to set this in motion - how often
should ID be sent, how fast, on what sideband (to correspond to the
operating SSB frequency). The op should have a choice of turning it on and
off, not to slow him or others down, not to cut into his transmissions etc.
Operator's action should have precedence over logging program actions. When
ID has not been sent in its entirety, skimmer should ignore it or wait for a
successful re-identification.

I'm sure there is a bit of intelligent analysis required on how to make this
work for everyone. CW ID can be very short (fraction of a second), it would
not slow things down, it (hopefully) would not be viewed as an annoyance
(unlike an end-transmission beep in the commercial world)

In my view, it needs to be experimented with before it becomes a mainstream,
in or out of contests

What we have seen in CW contest with skimmers basically changed how we
operate, where we operate and how stations are spotted. Perhaps this is an
easy and inexpensive way of bringing this technology to SSB. I don't think
FCC should object since maximum allowable CW speed is not an issue -
transmitting station identifies itself in voice anyway.

I'm not a member of any forum where this can be turned into a disussion, and
eventually - into someone's action.

Can you help and post this someplace on our behalf? This would be great

Thanks and 73
