[SignalOne] Milspec 1030 C low pass filters

Hello to the list,

studying the manual and photographs of a 1030 C more closely showed
without doubt that the transmit low pass filters are definitely below
the receiver compartment. And they are not switched by pin diodes
(that would need expensive high current diodes and a generator for a
200-V-reverse voltage!) but with low profile pcb relays.

The problem of excessive ALC overshoots has not been reengineered from
1030 to 1030 C. I will do some research about this problem and inform
the list about my results.
