Hello, John. Do you need metric or inches?

Please be aware that aircraft radio installations both in the 8th Air Force and other units, were dependent upon the time frame. A typical B-17 radio installation in 1942 was not necessarily typical in 1945. It was also dependent upon the theater in which one was operating.

37% casualty rate for B-17 crews. Nasty odds.

Gents: In my above post, I mistook the P10 for one I have, which is the P8. The radiation concerns would be the same. I plead old age :D

Good Morning. Ex-Nuke worker here. The P-10 was installed in Spitfires forward of the control column. I believe it was also in Hurricanes. Image attached. There is no problem with the Radium as long as it is contained within the device. The radiation coming from it has decayed a great deal...

Do you have one of the tuning units that go in to large slot at the bottom? If not, I will be glad to send you one for the price of postage. General Electric BC-375 transmitter, part of SCR-287, which was installed in all U.S. Army Air Corps Heavy and Medium aircraft until late war, when it...

I believe the gentleman is asking about the "blade" antenna, not the ADF "football." The "blade" is the standard AN-104 antenna for SCR-522 VHF Command Radio, 100-155 MHz. The angle of the blade on the trailing edge is the "tell." Note that this could also be an earlier version, AN-74. Same...

Just saw your reply. Thank you kindly for your offer. I did find the manual I needed. Regards, David S.

Is there any chance of find an actual manual for the TR9D? The items you commonly see on the 'net are the "concept" prints from the Wireless overview book. They are not actual schematics and are missing many circuit elements. I have recently resurrected a TR9D and still have a few...
