[MRCA] Regency Radio Pallet

[chancewolf at me.com]

GPS TOD would likely load the same way it does in SINCGARS, via a time fill
cable from the system to the AN/PSN-11 PLGR or equivalent.  I don't recall
if you can get it from AN/PSN-10 SLGR or SAGR/ Centurion the same way.  NEMA
sentences won't help you, unfortunately.  

I would think the system would only hang up on TOD in some modes, wouldn't
it?  I have the Team Terminal computer display unit NOS here in the hopes
that I'd one day find more of the Team Terminal pallet, but.nothing's really
shown up.  Toronto Scientific had one of the RFOs and another component a
few years ago but wanted Toronto Scientific prices.  I've not seen anything
for Regency Net since apart from a Force Terminal display unit awhile ago on
the E-Place, and of course the mountain of the various test jigs for the
system at Murphy's, American Milspec, Fair Radio and some others.
Occasionally you'll come across a bunch of TN-612s for the Force Terminal
too.    

You have an ambitious project.  Hope you can find all the bits and pieces.
KY-65 and KG-84 demils show up now and then and 'fill the hole' but don't do
anything else.  I haven't seen either for about 2-3 yrs though.

Ok, so am seriously planning on starting on a new long term project. This
would be restoring and setting up a AN/GRC-215 Regency Network radio pallet.
This would include a GRC-215 transceiver, power amplifier, reference
assembly and digital control unit. No, I don't have and will not be looking
for the TSEC KG-84 or the KY-65A security equipment but fortunately they
include a bypass box on the pallet that allows you to use it without the
security equipment installed. 

The problem I see right now is according to the manual the digital I/O
control system, they call it the D/K assembly looks at the reference
oscillator assembly (RFO) and wants to load TOD (Time of Day) data when the
system starts and without a valid TOD entry the system is in fault. 

Been thru the book a couple times now and it looks like you had to use a key
loader like a KYK-13 or maybe a MX-18290 to load the TOD data. They also
have a GPS port on the reference assembly but cannot imagine that it would
be as easy as just providing NEMA data at that port. Anyone got any ideas? 

So far this is a hypothetical project, got a line on the pallet with most of
the hardware and now may be in a place where I can get the radio itself so I
am trying to see how much more would be involved with this.

Also posted this to the GRC-215 group, who would have thought! Have to
wonder if they have a GRC-106 user's group?
