[Heathkit] Running the HX-10 Marauder outside its cabinet

[Glen Zook]

The DX-100B uses the same cabinet as the Apache, et. al, except that it was painted a different color.  The DX-100 uses a completely different cabinet which is somewhat larger.  Both the DX-100 and DX-100B cabinets do provide quite a bit of shielding.

It is true that TVI isn't an issue in reality.

The Mohawk, Apache, and Marauder all used the same cabinet.  The Apache 
and Marauder have shielded enclosures for the PA.

I don't know if the DX-100 cabinet is the same or not.

However, I suspect that the rack would perform adequate RFI enclosure duty.

The only issues I have run across regarding RFI in the last number of 
years has been ONE squawk from someone in the neighborhood that happened 
to hear me through their portable telephone.

I pointed out that it was subject to Part 15, and therefore interference.

That ceased the grumbling.
