[Elecraft] KX3: use at <500-KHz

[Johnny Siu]

Hello Edward,
 
For my K3, I got high S meter readings for local MF AM BC stations.  However, for my KX3, I bearly got a reading on the S meter for the same station.
 

TNX & 73,

Art,

Thanks for your report.  Tonight I connected my 600m band inverted-L 
and found I could copy am BC stations local and in Anchorage 70-mi 
away.  I also could copy the ADIS station on 380-KHz and the RGPS 
beacon 3-mi away (usually a whopping -30 dBm on the SDR-IQ).  it 
registered about S4 on the KX3.

So with a 20-dB preamp sensitivity probably can be restored on 
630m.  The final question then is whether the KX3 is capable of 
transmitting there.  I would be satisfied with 0-10 dBm as that is 
all I need to drive my 100w amp (converted NDB transmitter).

I have been received 2800 km away on 495-KHz.
