There are a few models that put out 1000pps. I have one that I use for
overlaying the exact time onto video frames when taping the occultation
of stars by asteroids in order to determine the width and shape of the
asteroids.
The device is here

If you do'nt use GPS as time source than it's not essential. Time
software 
like TAC32 would tell you if it receives those "one pulse per second" 
impulses. Nowadays when cheap integrated GPS receiver/antena devices
like 
Deluo products are quite affordable, some people use them as time source

inputs to specialized software which usually thinks there should be some
Com 
port with GPS attached. When there is no free Com port available usually

USB-Com connectors are used just like for Icom receivers, and the
problems 
are similar. Seems that not all impulses which would be normally
processed by 
Com port come trough USB-Com connectors, at least not trough all of
them.

But this is likely offtopic for this list, so let's return to Icom
topics ;-)
