Are you talking about the TAPR/JAMSAT TrakBox?
I bought a nice one a couple years ago for about $200 USD shipped from
Canada. I found a turbo kit available from someone here on AMSAT to
speed up the CPU and installed it. The turbo kit if still available is a
bargain, new CPU, Y2K firmware, a faster crystal and another faster
chip. Apart from soldering the crystal, there is not much to do but
follow instructions.
I also plan to install a back-lighted LCD display to be easy on my eyes.
They work pretty well. The only drawback is the RS232 interface for the
KEPS. I am going to try and add an Ethernet to RS232 adapter so I can
use a browser to upload the KEPS.
What I like is that it has real time tracking, _doppler __correction
_and autonomous operation in one package. I don't think there is
anything on the market that has everything these have.
Assuming the lithium battery has not leaked and the kit is well
constructed, you should be able to recoup your investment. They are no
longer available.
