[ARC5] WWII SG Radar

[Bill KA8VIT]

The SJ radar on our boat works but is currently not functional due to power issues, (but we're working on that).
 
The USS COD is the finest WW2 submarine anywhere in the world today and the last remaining unmodified US boat from that era, (sorry COBIA).
 
She's totally intact.  No stairs, doors or other holes we cut for public access.
 
The only way in and out is through her original crew hatches and ladders.
 
If you're interested in radio operations aboard a WW2 submarine below is a link to a PDF version of a presentation I did for a number of different radio groups around the area back in the mid-2000s.

We still operate from the radio room albeit using an IC-7300 these days and her original long wire antennas.
 
Most all of the original equipment in the radio room has been restored and is operational except our main TBL-7 transmitter, (working on that too...  still...), but being that we are a bona fide museum we us it very seldom except for limited demonstrations and certain special events.
 
If you check out this youtube page you find videos of some QSOs I made a week ago or so.
 
As you can tell how I am dressed, it is already getting really good in a steel tube that is half-submerged in an almost frozen Lake Erie.

The COD also has a pretty cool youtube channel at:

Scroll down the page about half way for links to some cool pictures and video on our way to, from and in dry dock.
