Loss of two meter simplex frequencies IMMINENT in Texas!
Texas two meter simplex users stand to lose a large portion of available frequencies if proposed changes to the two meter band plan are passed by the Texas VHF-FM Society.In an effort to make room for D-Star repeater pairs, the Society has proposed a revised band plan that will take spectrum from two meter simplex users statewide.
Below is the band plan being proposed by the Texas VHF-FM Society:
146.450 - 146.490 MHz, High in/low out, 1 MHz offset, 12.5 kHz channel spacing or less, any
digital voice/data air interface technology suitable for the Amateur Radio Service that is compatible with the channel spacing. No analog transmission permitted.
145.520 Analog
145.540 Analog
145.560 Analog
145.580 Analog
145.600 Analog
145.620 Analog
145.640 Analog
145.660 Analog
145.680 Analog
145.700 Analog
145.720 Analog
145.740 Analog
145.760 Analog
145.780 Analog
146.420 Analog
146.440 Analog
146.450 Digital }
146.460 Digital }
146.470 Digital }--------------- Simplex allocations that will be lost due to proposed restructuring.
146.480 Digital }
146.490 Digital }
146.560 Analog
146.580 Analog
147.400 Analog
147.420 Analog
147.440 Analog
147.450 Digital }
147.460 Digital }
147.470 Digital }-------------- Simplex allocations that will be lost due to proposed restructuring.
147.480 Digital }
147.490 Digital }
147.560 Analog
147.580 Analog
This proposal was placed on the table at the March 1, 2008 General Meeting of the Texas VHF-FM Society and has yet to be voted on, possibly due to opposition from avid simplex users.
Contrary to public opinion, two meter simplex frequencies are regularly, and in some cases heavily used throughout the state.
A well-established group of simplex operators in north and east Texas have used the frequency of 147.420 on a daily basis since the mid 1970’s. While that frequency is not in immediate danger of being reallocated, other well used frequencies are!
A group of simplex operators around the Cedar Creek Lake area in eastern Texas that regularly use the frequency of 146.475 stands to lose that piece of spectrum.
146.500 is another frequency currently being used on a regular basis by hams from Dallas all the way down into the Waco area that is on the chopping block.
I’m sure there are many more frequencies all across the state that are in use that we do not know about! If anyone knows of other simplex frequencies in use in the state of Texas please feel free to e-mail me at WX5VHF@gmail.com
In an effort to display the utilization of these simplex frequencies I am asking for all Texas two meter simplex operators to attend and cast a vote at the Texas VHF-FM Society’s Summer Meeting that will take place at Austin Summerfest 2011. The meeting will be held Saturday, August 6th at 1:00PM in the Pecan Room of the Austin Marriott Airport South at 4415 South Interstate 35 in Austin.
In order to vote at this meeting you MUST be a member of the Society! To become a member you must download the form from the link below and send it back with $15.00. (I guess it’s sort of like a poll tax?)

I believe I speak for most all avid simplex operators when I say, I am in no way anti D-Star. New technology and operating modes are the life blood of amateur radio. What I am against is reallocation of simplex spectrum as repeater pairs! D-star or analog, a repeater is a repeater and should be placed on frequencies that are already allocated for that purpose. If all of the repeater pairs are in use then get on the waiting list; just as analog repeater owners do. What is the rush?
Hams always say “Use it, or lose it” when it comes to radio spectrum. Well, this time it’s being used and we still may lose it!
