Charlie,

The Hilltopper firmware is all pretty straight forward. I made some simple modifications to mine and it works FB. Sidetone frequency/offset, and tuning time are the things I changed. 5 seconds of tuning isn’t enough for my T1 tuner but 10 seconds is more than enough. A couple of build tips:

One more thing I forgot!
If you don't want ear splitting sidetone volume, change R8 to 100K instead of the 22K that comes with the kit. 72, Chas - NK8O

Thank you Bill for your patience and persistence, it was only my 3rd CW contact and not really sure of CW Net protocol ..... you did great to pull that much info out of the junk I sent !!

Re: 40m Net
Paul Goemans
Hmmm
Were you on at 0200z? I didn’t hear a trace. I think I heard a trace
of W2SH.
I then moved down to 7030 and worked W6PU in AZ. He told me he was
running a kW and a 6 element beam! Wow. Look him up on QRZ. Sure enough, 6
elements full wave Delta Loop rope beam, electrically reversible. No wonder he
heard me! I was running my S & S Engineering TAC 1 at about 4 watts out to
my Carolina Windom 80.
I did QNI the 80 meter net.

FT-243 FUN!
Rex Harper
4Staters, Many years ago, I hung out with a couple of pals, Darell WA3OPY & Ron AC5UR, who
both worked at ICM. Darell was their crystal engineer and
Ron was his right hand man. I
was working with QCMs (Quartz Crystal Microbalance) where we slathered bare quartz crystals with a patented
glue and stuck
compounds on top of
the crystal. Then
we put it into a holder of my design and pumped water over
the crystal face. Specific contaminents
in the water would bind to the compounds and change
the crystal frequency. We could then
determine the contamination level
by how fast the frequency
changed. That was another life
back in the engineering world
many moons ago....but
it fueled my interest in quartz
crystals. Darell,
Ron & I hosted a
workshop at Ozarkcon in
Joplin Mo. where we
showed how you can take
a 'worthless'
6900+ military
surplus FT-243
crystal and grind it
to 7030. The 7030
frequency was just recently (at
that time)
declared a QRP frequency
of activity
and nobody had
any crystals
then. I
designed a
little crystal
oscillator and
measuring
technique for
the workshop
where we could
oscillate
& measure
the frequency
of the quartz
slab without
having to put
it back into
the FT-243
holder each
time you
wanted to
check your
progress. I
seem to
remember we
had about 35
QRPers all
grinding away
and every
one came out
with a working
40m FT-243
crystal... That whole process was updated and used for my FDIM Buildathon in 2017 but I added a direct display frequency counter to the oscillator to replace the frequency counters we had to round up way back when. That design was recently reviewed by none other than Bob Allison WB1GCM in the ARRL lab and written up in the November issue of QST. All hell broke out and I was kitting & shipping the X-CHECKer kits for 2 months. I finally caught up to the end of the list leaving me little time to much of anything else. Along the way, I redesigned the board one more time to make the kit a little easier to use. So there are lots more hams out there having lots of FUN grinding crystals. The other point of this email is to let everyone know that I now have a decent supply of brand spanking new FT-243 crystal blanks that make grinding a custom FT-243 for the 40m band a breeze. I would wager that Im the only one in the world silly (or stupid?) enough to track down someone who is silly enough too (to listen to me) and make me FT-243 crystal blanks! I invested an entire SS payment to stock my shelves with another crazy item. These crystals are in the rectangular FT-243 form factor, AT cut and are pre-ground for 7015 +/- 1000ppm which makes them run between 7008 and 7023 so they are already in the 40m band to start. I've ground one successfully up to 7218 so they are easily ground to any 40m QRP frequency of interest. They make putting a vintage rig anywhere on 40m pretty easy. I probably bought too many but I had to in order to get the price down to a reasonable selling price. I have a 3 pack on my parts page for $22 + $3 S&H so you could turn 3 junque FT-243 holders into 3 nice 40m FT-243s on your favorite 40m frequencies for $25.

Paul Goemans
Rex,
A local ham buddy has one of your new X-Checkers, and loves it. He
showed it to me, great design. He is a NRR (Novice rig roundup) NRN (Novice Rig
Night) operator, so he needs crystals too!

Re: FT-243 FUN!
KD5ALD
Hello :) I have done a bit of crystal grinding myself ! Can`t say it is much fun though ! Can take serious time :) Crystals are ground on a machine ! All a ham can really do is lapping ! or he could chemically etch ! One of the major Crystal manufacturers Bliley the name was devised a method of suspending the finished ground crystal blanks in a solution of Hydrofloric acid to get the crystals to a very specific and accurate frequency ! Neverthless however it is done ! Imperative that the surfaces remain parallel and flat as possible !
