[R-390] Please spare us

[Kenneth Arthur Crips]

All of the arguments about which one is better the R390/URR or the R390A/URR at this point in time
is foolish.  Both radios filled a military specification and both did their jobs very well.  Instead of arguing which
radio is better the discussion show center on what is different and why they are different. I look upon old radios as a kind of historical document.  You are looking at the expression of electronic engineers of the past.
so instead of some of the pointless arguments we have this forum let us discuss why Collins radio did what they did. Fortunately at least for Collins Radio this type of documentation has been collected and published.  I wish there was similar documentation about rigs like the Lysco model 600 Transmaster which has to be one of the worst transmitters ever produced for sale, the engineers who designed this turd must have been drunk.
