[NJARC] IRE Alignment

[NICHOLAS SENKER]

I have just finished recapping a GE J-71 table radio  and am touching up the alignment.  The procedure (Riders 12-29) calls for a IRE dummy antenna for the RF alignment.  What does this mean?  I just used a loop on my RF generator and this seems to work fine.
Another interesting thing about this receiver (1940-41 vintage) is that the shortwave bands are dead while the broadcast band works fine.  While recapping I noticed a disconnected wire that was neatly clipped and tucked out of the way.  Reconnecting it to the band switch, I now get SW reception.  I recall a discussion on the Broadcaster about wartime radios having the SW bands  disabled, presumably to limit propaganda?  I think this was one of them?
