Someone asked for the RF Design issue containing the spectrum analyzer
article. It was in the January 1988 issue.

Another option is to build the Science Workshop spectrum analyzer
described in Ham Radio September 1986.
It uses a modified cable TV converter to scan 0-500 MHz and a UHF TV
tuner to scan 420-900 MHz. They sell kits for modules except the power
supply and cabinet. They also have a tracking generator (0-500 MHz)
and a digital center frequency readout module.

The prices aren't too bad:

	Basic Kit (Main and Ramp boards):

		SW-6006K (Main board kit)	$30.00
		SW-6006W (Main board wired)	$50.00

		SW-6001K (Ramp board kit)	$20.00
		SW-6001W (Ramp board wired)	$30.00

	Tuners:

		SW-5800 0-500 MHz cable tuner	$35.00
		SW-5810 420-900 MHz UHF tuner	$15.00

	Tracking Generator:

		SW-5900 (works with SW-5800)	$50.00
	
	Digital Frequency Readout:

		SW-6007	(works with SW-5800)	$39.00
		SW-6007W (wired)		$59.00

The 3 chip analyzer described in RF Design was said to cost $100.00.
For the same price you can have 0-500 MHz (SW-6006K, SW-6001K and SW-5800)
instead of 0-100 MHz.
