[1000mp] Real S9

[Art Searle W2NRA]

Hi Pete,

The history of my Mrk V Field is the same as yours.  And I've also felt the
receiver was a little week.  Thanks for the info.  I'd considered getting
one of those kits when I put in the Roofing Filter.  Now I think I will get
one.  Thanks for the tip.

I just finished building the Elecraft XG-1 signal generator.

So why am I talking about it here?  Because It puts out a calibrated 50 uv
on 7040.  After I built it, the first radio I hooked it to was my TS-930.
S9 right on the button.  Then I connected it to my Mark 5.  S6!

I had thought for a long time that the Mk 5 sounded "dead" compared with the
930, but put it down to DSP, etc.
Not long after I got the MK5, I put in the Inrad IF mod, and then a couple
of years later I substituted the roofing filter.  The radio also has
cascaded 400 Hz Inrad CW filters.  In the course of doing all that, I guess
I had turned the IF gain down too far - anyway, using the XG-1, I was able
to reset it to ~S9 at 50 uV - certainly sounds like the band is more open!

I expect the VG-1 is going to prove very useful, anytime I want to check the
performance of my antenna switching or bandpass filtering - and for $40, I
can't imagine a cheaper way to do that.
