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 "The Elecraft K3: Design, Configuration, and Operation" www.ke7x.com ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
