[Milsurplus] More TCS questions

Bob, Ray & Group,

35' Whip vice 30'.

There was supposedly a shorter whip actually made for use with the TCS (can't 
locate the nomenclature right now) but I don't know of anyone who ever 
actually found one of them.  May have been made for use on landing craft, etc.  The 
external loading coil would probably be required with it on both of the lower 
bands.

The few ships that I was aboard in the 60's and 70's that still had a TCS 
aboard mostly seemed to have it connected to an end fed wire.  I think that the 
one on Valley Forge was about 60'-65' long and ran more vertical than 
horizontal.  The only thing I ever recall the ships using the TCS for in those days was 
Harbor Common (tug control) on some 2 MC freq that I can't remember.  But it 
was on the tuning chart, complete with typical settings.

My TCS-14 loads a 45' horizontal wire on 75 with the external loading coil 
switched out.  On 160, I have to switch it in.  I suspect that in the "old 
days". the yard birds ran tuning tests and filled in the chart with settings for a 
range of freqs.  Especially since what antenna (length) might be assigned 
varied from ship to ship.  No two alike, even among the Essex Class.
