[FADCA] D-Star Status Request

Gentlemen, I am sorry that Neil has not responded to your request (if he 
has, I did not see any correspondence that indicated that he had).  I had to 
relinquish the position of frequency coordinator as I am now residing in 
another state.  However, I did not see that anyone was acting in any 
official capacity with FADCA.

Here are the frequencies we have for coordination if digital systems in 
Florida.

2 Meter:

144 Mhz ..........
144.91, 144.93, 144.95, 144.97, 144.99, 145.01, 145.03, 145.05, 145.07, 
145.09
145.51, 145.53, 145.57, 145.59, 145.61, 145.63, 145.65, 145.67, 145.69, 
145.71
145.73, 145.75, 145.79

As you can see there are some pairs within these frequencies, i.e. 144.91 
and 145.51, 144.93 and 145.53, 144.97 and 145.57,etc.  If your equipment 
allows you to set them up on offsets other than 600 kHz, you have addition 
options.

440:

430.050, *430.150, *430.250, *430.350, *430.450, *430.550, *430.650, 
*430.850, 430.950
431.025, 440.975, 441.000, 441.025, 441.050, 441.075, 441.100, 441.150
441.175, 441.200, 445.025, 445.050, 445.100, 445.125, 445.150, 445.175, 
445.200
445.250, 445.350, 445.450, 445.550, 446.025, 446.050, 446.075, 446.100, 
446.125
446.175, 446.200, *446.250, *446.350, *446.450, *446.550

* Are 100 kHz wide channels for high speed packet

As you can see there are a variety of "pairs" that are 5 megahertz apart or 
more. Depending on the ability of your equipment, you should be able to find 
"pairs" that will support half duplex, and in some cases, full duplex 
communications.  I suggest you monitor a select set of "pairs", check the 
FRC database and if there are no other stations you can identify that are 
operating on the frequencies you have selected to consider, submit an 
application for coordination to FADCA

Here are the frequencies that FADCA has to coordinate in the 1.2 mHz band:

.......... 1240 Mhz ..........

1249.000, 1251.000, 1298.000, 1298.050, 1298.100, 1298.150, 1298.200, 
1298.250
1298.300, 1298.350, 1298.400, 1298.450, 1298.500, 1298.600, 1298.700, 
1298.800
1298.900


Here are the frequencies for digital the FRC has on their web page (with 
their mispellings) and since they are not responding to your request for 
coordination, I suggest you take the initiative and determine the "pairs" 
that will be useable by your equipment:

23 Centimeter Band Plan
      Frequency Usage
      1240.000 - 1246.000 ATV #1
      1246.000 - 1248.000 FM Narrowband Links and Digital
      1248.000 - 1252.000 ATV #2
      1249.000 Digital/Packet, 2 mhz bandwidth channel
      1251.000 Digital/Packet, 2 mhz bandwidth channel
      1258.000 - 1260.000 FM Narrowband Links and Digital
      1260.000 - 1270.000 Satellite Uplinks, Experimental and Simplex ATV
      1270.000 - 1276.000 FM Rrepeater Inputs
      1276.000 - 1282.000 ATV #3
      1282.000 - 1288.000 FM Rrepeater Outputs
      1288.000 - 1294.000 Wideband Experimental and Simplex ATV
      1294.025 - 1294.175 Digital/Packet, 26 khz bandwidth channel
      1294.100 Digital/Packet Calling Frequency
      1294.200 - 1295.000 FM Simplex (narrowband)
      1294.500 FM Simplex Calling Frequency
      1295.000 - 1297.000 Weak Signal (no FM)
      1295.000 - 1295.800 STV, FAX, ACSB Experimental
      1295.800 - 1296.000 EME and CW
      1296.000 - 1296.050 EME Only
      1296.070 - 1296.080 CW Beacons
      1296.100 CW/SSB Calling Frequency
      1296.400 - 1296.600 Crossband Linear Translator Output
      1296.800 - 1297.000 Experimental Beacons
      1297.000 - 1300.000 Digital/Packet
      1298.000 Digital/Packet, 2 mhz bandwidth channel
      1299.050 - 1299.950 Digital/Packet, 100 khz bandwidth channel




If they are unresponsive (and it appears they have been) I suggest that you 
research the frequencies with the bandwidth you need that you can use with 
your equipment, monitor those frequencies and submit a notarized affidavit 
of intent to operate on the pair that you select with a copy of the 
documents you have submitted to them along with any proof of the dates you 
submitted them, and a notice to the FRC that their continued failure to 
respond to your repeated submission for coordination of a digital repeater 
has resulted on your declaration of intent to operate a repeater on 
frequencies within the frequencies authorized for amateur communication in 
the band.

If you know a lawyer you can consult with regard to serving the FRC with the 
notice that can help you word it so that you are putting them on legal 
notice that would may end up being helpful at some later date.

Remember, they are a coordinating body, not an authorizing body.  If they 
fail to respond to you (as apparently they have repeatedly) they have lost 
the ability to act in a coordinating capacity and they can not defend any 
challenge to your use.
