Hello Don.

I live off 290 and 1960/HWY 6 area.

I orders a NorCal QRP FCC2 DDS kit with the FCC1 Display. I am hoping to set
it up to run different rigs, as needed.

It sounds like you have a great setup up there in TN!

You really have a full size, 1/4-wave Vertical for 160 Meters?!?!?!?!

Bow,

I think I used to live not too far from your QTH back in the late 70's.  I
lived in the Heights area of Houston, near the intersection of W 24th Street
and Rutland (Ave?}.

The 815 is a pair of 807's in one envelope.  If yours is good, you could run
about 100 watts plate modulated with it, or use it as a modulator tube and
get enough audio power to modulate a 100 watt carrier.  I had never heard
that about the 815, but many of those tubes with multiple seals in the
envelope are notorious for taking in air as they remain on the shelf for
many years.

What kind of DDS VFO kit did you order?  Several years ago I picked up a DDS
vfo at Dayton.  It was made by S&S Engineering (if I recall the name
correctly).  It tunes up to 16 mHz, but I used it @ 7 mHz and multiplied up
with an old Eico 720 to work 10m, and it seemed to have near perfect
stability.
I used it with the recent ARRL frequency measuring test, and managed to
measure one of the frequencies (80m) within 0.5 Hz.  So if yours has clean
output, free of spurs, it would make an excellent vfo for AM or any other
mode, for that matter.

You ought to try to get in touch with John, WA5BXO and Otis, K5SWK.  They
now live somewhere north of Houston, near Conroe I believe.  They have been
tall ships on AM from the Houston area for decades, and could probably help
you.

BTW, does anyone in the Houston area know what ever happened to the museum
and collection of pre-WW2 radio publications that used to be in the building
that housed the Houston amateur radio club in the late 70's?  They had a
their own building and meetings were held on Friday nights, once a month as
I recall.  Part of the meeting was an auction that alternated between "good
equipment" and junk parts.  Some of the museum stuff was extremely
interesting, and would be highly sought after to-day, and the publications,
mostly broadcast related technical magazines from the  late 20's throughout
the 30's contained a lot of hard to find technical data and history of
radio.  They had some framed photographs of club meetings before WW2, and I
recall one picture listed the members, and one of the members present in the
photograph was Howard Hughes in his younger years.

I understand that the part of Houston where that building was located
flooded out during a hurricane a few years after I left.  I would hope that
all that history didn't get destroyed in the flood.  Someone told me that
the Houston amateur radio club disbanded in the 80's.
