> use YG-ZB to find islands

Yes - but my contact never carried a torpedoe on his last assignment.  
Job was strafing straglers & small craft.  & never in bad weather even
with an ASB aboard.  He cud see home fm 100 mi.s @ 5000.'

Incidentally, is it true three torpedoes wud buy u an SBD in the 
check-out line?

USAF had lotsa B24s in south pacific.  Indirectly know a pilot fm
near Rabal, New Guinea.  Story about him in Atlanta paper a month back -
survived a mission where many B24s lost on mission return.  11 of 50
ditched & 35 men lost.  Biggest no-shooting USAAF loss in WW2.  Naturally
nothing in art'l about BC-946 & ARR1 (ZB).

Note only one ASB per SBD squadron in '43 though 2 ZBs.  And, I bet, the ZB
emerged pre-1940.  & Ret. Cdr Collins sed ASB an undeveloped toy.  You
cud get a target visual b4 ASB'd see it.  But then he always flew in
the sunshine.

Note tnx to Collins, ASB rear-cockpit display mtg re-emerged.  It was
bungied under dash & if gunning req'd, it was un-bungeed & let dangle
fm rear freeing up space.  CAF's SBD so done... with a AA4RM-donated
display.

ZB sure is a TRF with power detector.  The MCW BCB carrier modulation
harks to the FM 38kc subordinate carrier dsb FM-MPX unleashed in '58.

I don't think the ZB modulation scheme would be so intuitive.  If you found
the intermittent YG carrier (as it's yagi spun), then what do you have?

There was a YH system to set on a beach.  You'd find your run-up point
with a ZB on the Landing ship - tho I wonder if ever used.  Wm Donzi
may know

Yep to MM, amazing the BC733/ARN5 system survives w/o change in 2005!
CAF's FiFi cud make a category-1 w. tube eqpt. if properly crystaled fer 
arpt.

Another wunnerful is the VOR doppler-modulated doo-dad.  No system-basis
change since '47.  Note qualification - yagi's don't "spin in the hat"
anymore.

And last, the term Yagi kept appearing.  We sure put that Japanese physics
to advantage, eh?  A fundamental in YG/H-ZB, ILS, VOR.  And in all cases
they were on the ground

How'd Japanese find their carriers in thick wx?  Mostly, I think, they
didn't.  But they may have put up scout planes to take fixes & help
vector the returnees.  Like to know more.

Neat subjects.

Oh yeah, the ZA and fb on ZA.  Never heard of it 'til now.   Ret Cdr Black,
Coronado driver, may have something.  & so too Ft. Monmouth / Bearcat-driver
