Heathkit SBA-2001-01 QSK Board for SB-1000 Amplifiers
$175 - Shipped
The Heathkit SBA-2001-01 QSK Board is supplemental transmit / receive switch that allows rapid operation on all modes. It is designed to be used with the Heathkit SB-1000 Linear Amplifier. The QSK Board can handle power levels as high as 1500 watts into a load that has up to a 2:1 VSWR. The switching time is less than 500 microseconds under worse-case conditions, and the attenuation to the receiver is less than 1.0 db. Supply voltages of 12 volts DC at 500 milliamperes is provided by the low-voltage supply in the amplifier, and 350 to 450 volts DC at 1 milliampere is supplied by the amplifiers high-voltage supply. This kit was supplied factory built! I have taken the liberty of measuring and cutting and attaching / soldering all the necessary wires along with the assembly of the mounting hardware. You will need to drill two (2) holes in the SB-1000 chassis to mount this board. Wiring changes to the SB-1000 are minimal and you should have this installed and working in less than 2 hours including the hole drilling. As new and works 100%
This is probably one of the rarest Heathkits available and if you own a SB-1000 amp and operate high speed modes, this is for you!
Here is the schematic of the board
