[Milsurplus] No GO-9 On Display. Likely GO-2.

[WF2U]

Mike and all,

I didn't give more than a cursory look at that transmitter in the cutaway display (I looked at it on my "smart"phone screen as I wasn't by my computer) and didn't notice the difference. 
I know that the GO-9 is paired with the double setup (including the double RU-19 junction box) of RU-19's, because it states so and is illustrated in clear photos in the PBY-5A flight manual, revised 20 January 1945 I'm looking at. The radio equipment listed and illustrated, not to mention components such as junction and control boxes, is as follows: command (intersquadron as the manual says) transmitter ATB,  command  receivers  2x ARB. Liaison transmitter GO-9, liaison receivers 2x RU-19. The manual also shows and lists an LM-10 frequency meter. The manual also notes that the ZA equipment was deleted from the equipment installation,  although it shows on the photos.

73, Meir WF2U/4
