[Elecraft] drift - a new solution?

[Indy]

I did not install the BFO mod because I do not have the K100 and I do =
not have much drift (20 cycles typical)...

BUT, follows is what seems to me a clever solution to drift applied to a =
stock FT-1000MP that led to total drift from start-up in the fractions =
of a cycle!!!!

I am wondering if one or more of our engineering aces might take a look =
at this to see if something similar might work for an Elecraft.  I am =

I have posted additional pictures of the ref oscillator mod that I made =
at
www.k0to.us . The pictures have links in the table following the home =

picture. The four pictures showing the reference oscillator board and =
the
modifications are DSCN4434,DSCN4435, DSCN4442 and DSCN4443. The
thermistor-resistor circuit is one that uses a 25V50/50C positive
temperature coefficient thermistor, (Mouser part # 527-3006-25V50/50C  =
about
$2.28) in series with a 1/4 watt 68 ohm resistor connected between =
ground
and the +9 volts on the board. One lead of the thermistor is soldered to =
the
case of the crystal and from there to ground. The other lead of the
thermistor goes to the 68 ohm resistor which has its other end connected =
to
+9 volts. The thermistor should be physically touching the crystal case =
to
assure good heat transfer. Remove the board before working on it. Scrape =
the
metal case in a thin line so that you can put a bead of solder on the =
case
(20 watt iron is plenty hot). Then solder the thermistor lead to the =
case
along the solder line. Dress the ground lead to the bottom of the board =
per
the picture. Connect the 68 ohm resistor to the +9 volt point shown on =
the
picture. Use insulated tubing to protect the leads from shorting.
