[Elecraft] VB: Reason to NOT buy a K3?

[Edward R. Cole]

Samir,

Using the K3 as IF for connecting to XV-144 or other transverters 
should work just fine.  I am using my K3 on 28 MHz to operate on 
1296-MHz with a 1296/28 transverter.  I ordered the 25w transverter 
set to drive with 1.0mw.  It runs 5w with 0.25mw and full saturated 
output of 20w+ with 1.2mw.  This is thru the KVX3A.

If you are concerned whether the K3 receiver will be adequate, there 
should be no concern since most transverters have conversion gain 
driving the IF with amplified signals.

My Downeast Microwave transverter has 17-dB conversion gain; this 
means the noise figure of the transverter will dominate, improving 
the receive sensitivity by 8-dB to -148 dBm.  In my case, a lower 
noise figure preamp is located at the antenna to further lower the 
system noise and improve minimum detectable signal (MDS) to -158 dBm 
(400-Hz bw).

Hello,

How's about performance on 10M band? I'm thinking to use K3 like IF 
to my XV-144. Now I'm using K2.

K3 wasn't on market when this list created,

different HF RIG's on 14 MHz and 28 MHz...

Thank You
