5MHz band soon - restrictions?

Well, I will be surprised that anyone modifies their
Collins 32S3B since there were none marketed (there
may have been a test unit, or two)!  The 32S-3A is the
last of the S-Line transmitters.

However, the Collins S-Line, with the 2.1 KHz filter
(which is standard) meets the 2.8 KHz bandwidth
requirements.  Also, Collins approved most of the 5.0
to 6.5 MHz range including all of the proposed 60
meter band in Service Information Letter 2-75.  All
that it takes to put the S-Line or KWM-2 series on 60
meters is to plug an 8455 crystal into one of the band
2 slots (band 1 doesn't work - already tried it!) and
that gives coverage of 5300 - 5500 KHz which takes in
all of the 60 meter band.

As for modifying other equipment, some of it will work
fine and some won't!  That is the "breaks of the
game".  Remember that when 15 meters became an amateur
band around 1950 that most of the rigs didn't cover it
then.  Also, when 6 and 2 meters came into being they
were different from the old 5 and 2.5 meter bands and
required new equipment.

One thing is that since most equipment will have to be
modified, that most of the "trouble makers" (jammers,
etc.) won't take the trouble to modify their equipment
just to play havoc with the band since they can cause
all sorts of problems elsewhere.

What does this last part mean?

Now we have to MODIFY our surface-mount constructed
$2,000.00 Japanese black boxes to USE that sorry
excuse for a "Band" ???

Who will be the first to modify their 32S3B to comply?
