[Milsurplus] L-5 Liaison Aircraft Radios

[Charlie L.]

Not RCA, but the Lear set up in the attached pic looks very similar.  I had
a story in ER a year or so back about getting a Lear UT6A on the air, and
it is still working fine.  Runs on 28VDC and puts out about 35 watts.  Mine
is 4 channels, auto channel select with 4 preset grid and tank capacitors
for max output from 3 to 7 mhz.  The original UT6 had 6 channels, and two
had to be within so many percent of two others as they shared grid and tank
caps.  This UT6A apparently went to some form of rework or modification
center, as the changes made to it for only 4 channels were very clean and
professionally done, and the nameplate was stamped with an additional 'A'
after the original UT6 stamping.  Took quite a while to get info about this
gear as just as I was needing info, and there was none on the internet, the
Lear organization had just sent all their documentation about  Bill Lear's
work to the Museum of Flight in Seattle, WA, and it was all still in boxes,
a lot of boxes.    Then  along came the Covid restriction idiocy and made
the task take more than a year.
