[ARC5] BC659 dummy load

[WA5CAB at cs.com]

No.  I'm sure that at the time, and in the US Army, it would have been a 
thermocouple type, so much lower resistance than 300 ohms.  Thermocouple type 
RF milliammeters are not easy to come by today.  A 1 ohm resistor at the 
ground end of the 300 with a decent 'scope across it would work fine.
