This is a Heathkit HF station based on the SB-104 transceiver. It includes the SB-104 transceiver, and matching HP-1144 AC power supply. The individual items are listed below, but the station is being offered as a set.
Drake 1 Kilowatt maximum below 30 MHz Low Pass Filter - 52 Ohm impedance. Rated greater than 80 dB attenuation above 41 MHz.
Unit is is physically in good condition with no dents. Testing pending.
This is a solid-state square wave generator that covers 20 Hz to 2 MHz in 5 decade ranges. It incudes an attenuator with 6 attenuators that can be switched in (1, 2, 3, 10, 20, 20 dB) allowing up to 56 dB of attenuation. Sine wave output is 0 - 6 volts RMS into a 600ω load. Square wave output is 0 - 10 volts peak (nominal). No manual; operating manual is available on web.
It is in good physical shape, though it is a bit dirty. Unit operates but is erratic in stability; possibly just a feedback adjustment.
Old HP-400C audio voltmeter. 1 mV RMS to 300 V RMS in 12 steps (10 dB steps). Unit has 10 tubes including ballast tube.
Unit is dirty; leather handle needs repair. Unit is physically complete with no major dents. Unit was powered up (properly) and was found not to work. Among other possible problems the ballast tube is inoperative. Good for parts or a full restore job.
This unit has two meters, one for current and one for voltage. It is rated at 13.8 VDC at 20 Amps ICAS and 16 Amps continuous.
This is the single metered version of the dual meter unit above. It has a meter switch to select voltage or current, and is rated at 13.8 VDC at 20 Amps ICAS and 16 Amps continuous.
This is the unmetered version of the RS-12M. It is rated at 12 Amps ICAS and 9 Amps continuous. This is an older style with a bat handled ON-OFF switch.
Physically, the unit is in good condition with no dents. Outside needs cleaning and removal of a piece of masking tape remnants. The switch is broken and needs replacement. It appears this unit has been modified slightly by the addition of a pilot lamp on the front panel (lower right) driven directly from the 13.8 VDC output. There is a problem with the voltage adjusting circuit, causing the OVP circuit to trip.
This is the unmetered version of the RS-35M. It is rated at 35 Amps ICAS and 25 Amps continuous. This is an older style with a toggle ON-OFF switch and separate pilot lamp.
Physically, the unit is in good condition with no dents. Outside needs light cleaning. Unit was tested unloaded on the bench and puts out 13.7 VDC with no noticeable ripple voltage.
This is a classic 1958 5" Heathkit Oscilloscope, Vertical response 3 Hz - 5 MHz (5dB down).
Unit was powered up (properly) and displays a trace. HV recitfier is weak.
Ramsey compact frequency counter. I couldn't find much on this item. One website had it rated at 60 MHz, another had it rated at 100 MHz. It has eight digits and two time bases: 100 mSec and 1 Sec. Also has built in scaler and BNC input connector. Size approximately: 6-1/4" W x 4-1/8" D x 2" H.
Unit is in good physical shape, with one small bend at the very end of the right lower front of the cover. Display has one segment intermittent on the six MSD digits and an additional segment out on the MSD. Unit has possible modification, there is a resistor with one leg unconnected on circuit board.
