>>>Thoughts: I realize that all s-meters read differently and the fact that the MP s-meter shows a 4 s-unit stronger signal above the noise level doesn't mean alot.
Correct, 4 S-units on an MP meter at that level is probably more like 2 real S-units (10-12 dB). See below: http://www.mail-archive.com/elecraft@mailman.qth.net/msg63910.html >>>But the fact is that the signal on the MP sounds MUCH louder with alot more headroom above the noise level. The K-3 receiver sounds so noisy even with the S-7 signal that it isn't enjoyable listening to and that's why I ran the comparisons because I couldn't stand all the noise. Switching on the K-3's NR, ATT, and/or adjusting the RF Gain does help some but the signal still sounds noisy compared to the MP. CONFIG: AGC THR may be set too high. Try a lower setting. Also, for a given band/antenna combination, set ATT ON>ATT OFF>PRE ON in that order and stop when connecting the antenna gives you band noise (i.e. don't use any more gain than necessary). This ensures you are not wasting dynamic range by setting the noise floor correctly. After doing this, I set my AF GAIN knob to about 9-10 o'clock (for headphones) and adjust RF GAIN back for a comfortable volume. If you run RF GAIN wide open the receiver will sound noisy and you are limiting your dynamic range. 73, Bill -- View this message in context: http://n2.nabble.com/Noisy-K-3-Receiver-tp4173832p4175133.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
