[time-nuts] Beginners GPS locked frequency counter question

I have a Racal counter locked to 1 MHz on its rear panel external
input socket from my Trimble Thunderbolt GPS. I derive the 1 Mhz
from a David Partridge divider board. If I also feed the counter
with the 10 Mhz direct output from the same GPS it reads one or two
Hz out. As I assume the counter is working purely mathematically
why would that be please?
As an aside, I work low frequency RF transmissions on 136 Mhz, and
very narrow bandwidth. Can a soundcard be locked to GPS instead of
its own internal crystal for precise frequency output?
