K3 #296

mark roz
I like my K3.RX is so quiet. Very crisp CW tone and
super clear SSB reception.

However I have some small problem's :

1. On SSB with headphones plugged in and noise
reduction engaged, during transmission the audio
comes from the internal speaker in the form of short
bursts. It is impossible to transmit with NR in ON
position. In the menu, speaker is on 1.
This will happen more often if RF gain is decreased
and when shift is being adjusted. VOX is ON.

2. On SSB only. When NR is engaged noise drops but
also the level of the main SSB signal will drop
significantly. On CW is perfect.
I'm sure that this could be corrected in software.

The one thing I don't like about VOX is the fact that
its sensitivity is NOT independent of MIC gain like in
FT1000D. This probably cant be changed in software.

For those who didn't try very good quality MIC on SSB
I strongly suggest to do that. The transmit audio is
superb. HC5 is good but doesn't even compare to  
Goldline Pro or condenser MIC.

Question: Do I need 6kHz filter in order to try ESSB.
Can't find it in the menu.
