Switching requirements of SB-200?

[Doug Person]

Is anyone familiar with the SB-200 and its switching requirements? Is it
something the K3 can handle?

Thanks & 73, Doug -- K0DXV

The relay switching voltage is NEGATIVE - about -150 volts.  
Not something to connect to the K3.  You will either need
an external buffer like the Ameritron ARB-704 or - better -
convert the SB-200 to low voltage switching with a product
like the Harbach "Soft Key."  See:
