I don't know if this will work for you, but I just set the rig (IC-7200) to the AM broadcast band in CW mode, tune off of a station to get rid of the carrier tone, and practice CW that way. I only hear one tone. Seems simple to me. ??
Actually, I don't think it was that many. The thing is, this is not history, unless it's history in the making. This real, and the threat is for millions of people dying from radiation poisoning. If Fukushima Nr. 4 continues to what may be it's logical conclusion, we may all be history.
The thing the bugs me is people that mention an item in the for sale section, when all they want is the item. They don't have it for sale. I've wasted a lot of time this way. A simple 'WTB' would let everyone know they want something.
I joined Army MARS about '75 or '76. Stayed with it thru 2 overseas assignments, to Germany and Korea. I actually got a couple pieces of equipment: An R-390 and a tube tester, but have neither now. I quit MARS after 20 years because 95% of the activity was a couple of nets a week with check-ins and comments. When I retired in '06 I thought about joining again, but all of the additional new training and requirements put me off, and I didn't rejoin. WX4O
When I was in the Army Security Agency, one of the main things I did was called 'RFP' or Radio Finger Printing. We identified transmitters sending CW routinely using a special recording technique. This was in 1964-1967.
