HP 8672A signal generator. 2-18 GHz. Blows fuses when plugged in. I believe it is just a problem in the oscillator oven circuit — which is the only thing turned on all the time. Should be an easy fix. I have the manual for it. A bargain at $250. Fully operational HP8970A Automatic Noise Figure Meter, with a calibrated HP346C noise source, good to 26 GHz/ The 8970A is good to 1500 MHz. $1100 for the pair. Calibration of the 346C was $1200 when I had it done. Comet CF-360 Duplexer, 1.3 - 30 MHz and 49-470 Mhz. $50.00 Comet CFX-324 Triplexer, 1.3 - 150 Mhz, 200 - 320 MHz and 390 - 500 Mhz $65.00 Both units are in very good condition Radio Shack 12VDC - 120VAC inverter. Looks new… $35.00 Downeast Microwave 6M transverter, 28 Mhz, 1 watt in, 50 Mhz 25 watts out. $175.00 Downeast Microwave 2M transverter, model 28-144 INT. Low power. This item used to convert 28 Mhz to 144 to use with microwave transverters. $150. This is almost new. Shipping extra. I don’t recommend shipping either of the HP units. I can meet you half way to deliver. Thanks and 73, Dave, K4TO ___________________________________
