PENNNYLANE - Two Stage Companion Exciter to Mercury
The Pennylane two stage digital up converter (DUC) is a 1/2-watt transmitter/exciter board. It makes a good companion to the Mercury HF direct sampling receiver board. When connected to the Atlas (bus) it will process the I and Q signal from the personal computer.
