Check back in Jan 2004 QEX. There was a construction article on a nifty
little calibrator that you can build cheaply that would work perfectly.
It was written by K3NHI. It used a CMOS clock, battery and a few other
parts, and only requires a DVM to calibrate.

I recently built the rf power meter discussed in the last QEX and QST
issues. It was a fun project and works very well. However, it needs to
be calibrated and this requires either an accurate (i.e. calibrated)
reference meter or a calibrated rf signal generator capable of -70 dbm
to +7 dbm (or somewhere close to those numbers). Unfortunately, no one
in my local club has such equipment and several calls to possible
sources have not been fruitful. I am located in Alameda, CA. Does
anyone have a calibrated signal generator or know where I could get
access to one?
Thanks
