Hi all,
Like many, I haven't been able to find a decent pileup the last few days
to test the version 4.51 AGC. I don't use the NR or notch function
either so have concentrated on making some measurements using the XG3 as
a signal generator.
The figure on
http://www.ke7x.com/home/miscellaneous-k3-information/agc-4-51 shows
some measurements I did with the 4.51 version AGC using the XG3 as a
signal generator. For each of the three signal levels from the XG3 --
-107, -73, and -33 dBm, I used the 10 dB attenuator and 10 dB preamp to
get 9 different signal levels.
Observations:
As THR increases, the effect of SLP decreases. At THR=20, SLP is
essential 15 for all values of SLP (I tested SLP=0, 7, and 15). This is
the upper curve on the figure. As THR decreases, SLP begins to take
effect. At THR=15, SLP values between 0 and 7 are the same while between
7 and 15 an effect is seen. At THR=8 the full range of SLP is effective.
Changing SLP behavior as a function of THR has been done to protect the
user's ears.
73 and cheers,
Fred, KE7X
