Don't know. If the HP has a serial port to accept commands then it could.
Also, I saw an HPIB XT card on e-bay once. That would be fun to use for data
acquisition from the HP if it has the HPIB interface.

And thanks for mentioning the rotor! In fact, I do have a
computer-controllable rotor from my Oscar days. Gotta get that in the mix.
Looks like I need to get more serial ports...  8-)

It sounds like the computer will run the VFO and rotate the loop and do a
capture and fire up the little zapper that lets you know in the middle of
the night that it has seen a signal. You'll have to ignore the Looper Band
so you can get some sleep though!!! That sounds like a neat program. Could
it be made to run my HP 3586C???

I, too, have been dabbling in this area. But coming from a different aspect.

I have been playing with Spectrum Lab and it's ability to "dump" the FFT
buffers to a file. I am working on (simple) software that would massage the
data at a point between the FFT engine and the graphic display. This also
opens the possibility of using other plotting programs/software to display
the data.

This started as a program to compare the energy at frequencies around the
desired signal with the energy AT the desired frequency. With appropriate
averaging (still TBD) I feel that I can have the software alert me that it
is possible a signal is present. Combine this with computer control of my
Icom receivers and it is *possible* (in my twisted mind) to "scan" all
lowfers and get informed when energy (a signal) is present on the frequency
that is not present on adjacent frequencies, i.e. not wideband noise.

The software is real and I have some interesting results but nothing to
publish yet.

Thoughts?

Mike
