Remote Panadaptor : Question on K3 i-f buffer amps...

[Gerry Hull]

Hello All,

I have worked with Tom, N1MM ad we now have a running remote spectrum
window running.
It's an AirSpy HF + at the station and a copy of N1MM+ which is forwarding
the XML spectral data.  Using this mode, it only uses about 6 kb/s for
spectrum display and works VFB over a very limited DSL connection.

Right now, I'm using the K3 i-f output.   It's a bit low.   I've seen some
chatter on i-f preamps for the K3, but can't seem to find any.  I need one
that has the decent filter so the LO doesn't clobber it.

Any ideas?

Gerry,

Was your K3 purchased before about 9/1/2009?
If so, it may not have the IF buffer mod installed which increases the
gain at the IF output by about 10dB.

See  IF Output Buffer Gain Modification  in the listing of K3 mods.
