Changing "R" to a slower transmit rate is a matter of changing an input
parameter in the C-64 program that keys my beacon, and it takes less
than a minute to execute the change. I estimated a number that would
get me somewhere near QRSS-30, then entered that value and timed the
dot length that it produced. So beacon "R" is now transmitting QRSS-50
- the dot is close to 50 seconds long by stopwatch. The dash is 150
seconds, etc. - standard keying. This should work good at your QRSS-30
setting because there is just the one character in my ID.
I made sure that the beacon was running maximum possible antenna
voltage, and the string of neons is lit up brightly.
As for frequency, the really critical thing at your end, I took note of
the 7 Hz window in your screen shots of those other beacons. I tried to
get my old frequency counter working so that I could give you a better
target, but it's hopeless; the counter was actually dead this time. The
last time it worked right the beacon read 169.863 kHz, but that was
years ago. The Counter read 169.882 right after I moved to Cotter and
constructed the existing antenna, but I had doubts about the counter at
that time. The crystal itself is a fundamental and is the size of your
thumb! It is not in a STALO oven (something that needs doing). The
value stamped on the metal case is 169.800 kHz. If you have the
patience, try starting at 169.860 and scan 25 minutes, then move up
about 6 Hz, etc.
If I were to guess, R in Cotter might get out 25% of the signal radiated
by my better Oklahoma beacon.
Please pass this info to the others.
