To me, '73' is merely a code, or token that stands for something else. In this case it is "best regards", which is plural. I just make a simple substitution: '73' instead of 'best regards'. Is that too difficult to comprehend? 73 --Steve Hideg hideg@erim.org p.s. My repeater beeps and has an autopatch.

In the Atlanta Journal, the story said that they found an excess of nonlymphocytic leukemia of 1 in 200,000. IE 7 cases instead of the expected 6 in the sample. Now I'm not a mathematician, but I'm not convinced that's a statistically significant change. I thought that probabilities on the same order as the sample size were considered meaningless.

The temperature gradient is reversed from 60N and the pole in the middle and upper stratosphere from 30 HPA upwards and in the lower stratosphere during the next day.

Only minor optically uncorrelated B-class events were recorded this period. A limb event in the form of an eruptive prominence occurred on the west limb at S16 between 31/0601Z and 31/0735Z. Maximum radial extent was 0.29 solar radii. Region 7698 (S17W11) has shown some growth over the last 24 hours. All other regions are stable and quiet. Solar activity forecast: solar activity is expected to be very low to low. Region 7698 exhibits the best chance of producing C-class activity. The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Geophysical activity forecast: at middle latitudes, the geomagnetic field is expected to be mostly unsettled on day's one and two becoming active on day three. At high latitudes, the field is expected to be unsettled on day one, mostly active on day two with active to minor storm conditions likely on day three. A favorably positioned recurrent coronal hole feature is expected to produce the activity beginning on day two with active to storm conditions likely to persist through 11 April. Event probabilities 01 apr-03 apr Class M 01/01/05 Class X 01/01/01 Proton 01/01/01 PCAF Green Geomagnetic activity probabilities 01 apr-03 apr A. Middle Latitudes Active 15/25/30 Minor Storm 10/15/30 Major-Severe Storm 05/05/10 B. High Latitudes Active 15/25/30 Minor Storm 10/15/35 Major-Severe Storm 05/05/15 HF propagation conditions were normal over all regions. Normal conditions are expected to persist through 02 April. On 03 April, a well-placed coronal hole is expected to begin elevating levels of geomagnetic and auroral activity. Minor to major storming is expected to accompany this disturbance over the ensuing days in early April. Based on recurrence, this disturbance could keep propagation conditions well below normal for most of the first two weeks in April.

People can react the same way to a squelch crash as to a beep. I've experienced one beep system that *does* tend to cure bad habits, but I found it too obnoxious to implement. It uses twin beeps. If you key after the first beep, you get 10 seconds before repeater time out. If you wait for the second beep, you get the normal 3 minutes. The gap is for breaking stations to insert their callsigns. Getting everyone to patiently wait their turn in a conversation is a lost cause when you have 5 or 10 people all wanting to get their two cents in a hot discussion. It's the cocktail party, or beer and pizza, syndrome except that when several people try to talk through the repeater at once, you can't understand everyone. Even so, the tailgating and doubling are preferable to a stuffy ordered roundtable. Ideally, we'd all have duplex radios so we could do CSMA. For now, the best we can do is try to avoid being long winded since we may wind up having to repeat everything after we unkey and realize we were doubling for the whole 2 minutes. :-( Gary -- Gary Coffman KE4ZV | You make it, | gatech!wa4mei!ke4zv!gary Destructive Testing Systems | we break it. | uunet!rsiatl!ke4zv!gary 534 Shannon Way | Guaranteed! | emory!kd4nc!ke4zv!gary Lawrenceville, GA 30244 | | ------------------------------ End of Info-Hams Digest V94 #366 ****************************** ******************************
