[Lowfer] The slant

>Bill, seems like I remember you using a slant some last year ... didn't
you?

Yah, in fact all my normal transmissions on 185.300 have a slant somewhere.  
I've tried different ways to insert this into my ID and to determine the 
effect on reception. The initial concern was that a slant would not be as 
compatible with ARGO as a horizontal dash. I sent Identifiers containing 
different patterns of slant/no slant and slants of different slopes. The 
findings for weak signal conditions using QRS30 were:
a) A 45 degree slant was the easiest slant angle to see.
b) About 60% of the time a slant was easier to make out than a dash.
c) Most importantly, the use of one slant at least every other ID made 
identification of WA a whole lot simpler and more positive. Equivalant to at 
least a 2db signal increase <G>. (Do I need to point out a certain ID 
question that occurred today with a familiar beacon?)

    I like that idea, and think I'll try that this year .... perhaps throw a
slant in once an hour or so between QRSS30 IDs covering, say, .2 or .3 Hz
at that speed?


I'd go for the' between ID's' approach, or between every other ID. or 
actually make one of your ID dashes a slant. This would help set you apart 
from other 'slanter' beacons in a crowd, should this idea catch on. Don't 
neglect the fact that you can slant either up or down.

The amount of FM is determined by the QRSS speed. It seems your .2 to .3 Hz 
is about right for 45 degrees .... and wouldn't get in anyone's way (unless 
you want it to <G>).

PS: Is anyone else having their postings to this reflector rejected as spam? 
IE: "that 2db...." subject of mine and "slant insertion". Well maybe I can 
see the reason for that <G>
