[Elecraft] K3 & RemoteRig

[Paul Christensen]

Still getting used to a recently installed RemoteRig used with my K3 and 
K3-mini.  A few questions:

1) Since the K3's RS-232 port is wired directly to RemoteRig, is there a way 
to access control of the RS-232 port for firmware upgrades, SDR-IQ control, 
etc.?  As it is, LP-Bridge doesn’t appear to apply here since the K3 is not 
connected as a PC COM port;

2) Any means to monitor mic audio on the K3 mini while transmitting?  I've 
tried bringing up MON audio, but nothing heard.  I thought perhaps the K3 
mini would inject local mic monitor audio into the receive audio.

3) K3 mini speaker audio is extremely loud and the CW sidetone is even 
louder.  However, receive audio and sidetone in headphones is excellent. 
It's as if there's a gain structure problem just ahead of the speaker amp. 
Any way to easily reduce speaker amp gain after the AF control?

4) Consider a situation where two K3 minis are each trying to access a K3 at 
the remote site.  When one of the K3 minis connects to the remote site, will 
the other K3-mini's display read "busy" or in some way let the user know 
that the K3 is being tied up by another user?  Or, must we rely on the green 
PWR/connect light on RemoteRig?

Tnx!
