SKY COMMAND VHF FREQUENCY COORDINATION                    3 April 2007
----------------------------------------------------------------------

Sky Command as implemented in the TS-2000 requires both a UHF and VHF
freuency for the links.  UHF will not be a problem in most areas
because we have many more MHz there and there are plenty of unused 
left-over *packet* channels there for the UHF link.  But 2 meters will 
be a MAJOR problem in most metro areas.  

Here is my recommendation for how to avoid the 2 meter band congestion
problem of implementing SKY command in METRO areas:

1) Put the "VHF" link on 220 or 900 or 1296 MHz.
2) Wire the TS-2000 SPEAKER to a 220 or 900 or 1296 transmitter.
3) Put the VHF cable of the TS-2000 into a dummy load 

Although the D700 can receive on 220, 900 or 1296 and can operate on 
UHF at the same time, Sky Command appears to take the Band B for the
packet link and so then you do not have band B for the  220,900 or
1296 receiver.  Bummer....  Too bad we cannot select band A for
Sky Command packet link so that band B can be used here for the audio
link on these other bands.

But it can still be used if the COMMANDERS are willing to have 
another scanner or radio in their mobiles to monitor the 220, 900 or
1296 band audio link from the TS-2000 system.

Another advantage of using a coordinated channel on 220, 900 or 1296
is that it will then allow you to more or less keep that audio link 
up most, if not all the time too for ease of monitoring.
