Howdy - could the units have switch mode power supplies instead of transformers to reduce the voltage? Poor design switch mode supplies generate LOTS of RFI. Tom, W7QF >>The few schematics I've reviewed (the actual schematics tend to be trade secrets and the guts of these things are usually potted to make quick reverse engineering a bit challenging) show that they run on AC, using a transformer or running a string of diodes in series _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.contesting.com/mailman/listinfo/tentec |
