[Milsurplus] RAK/RAL usage

[Robert Goff]

I was wondering if anyone could confirm some particulars on the usage and 
distribution of RAK/RAL sets.  I've been told they were used in all 
submarines through the end of the war, rather than being replaced with 
RBA/B/C sets in '45 as was done in many other ships.  The impression I got 
was that this was done because of concerns over reradiation by 
superheterodyne LO's but, are there other factors as well that played into 
this as well?  Availability?
Thanks,
Robert
