Respectfully and only with respect -- I think it suggests a lot about character when I read your reply Mr. Dengler. TASMA does not *yet* have a band plan but you are fully aware of a motion placed before the board recommending the continued use of the SCRRBA band plan as it exists. Therefore, TASMA has a 70cm band plan. http://forums.scaroa.org/showthread.php?p=16posted=1#post16 This is a partial list of the WIN System that features repeaters with overlapping coverage, but granted coordination.

I believe that most of us know that on 440 1) most repeaters are limited range and private and this practice absolutely does not serve amateur radio operators, and 2) one has to pay to play.

Who's invited? Yet another closed door meeting? One entity conrolling all spectrum will only add to the corruption most of us know takes place but say nothing about because we're already coordinated and don't want to find ourselves penalized for having an opinion.

[Repeater-Builder] A Home Brew 224 MHz Repeater Project. - Part 2
A Home Brew 224 MHz Repeater Project. May 2009 Part 2 The Receiver First Post May 2, 2009, this post May 6, 2009 This text is part 2 of a description of a recently completed 224 MHz Repeater Project. One could easily apply the same techniques toward a repeater project in different frequency ranges. Pictures of the completed repeater project reside in the group photos section. http://groups.yahoo.com/group/Repeater-Builder/photos/album/1157128983/pic/list I selected a Hamtronics R302-6 Receiver for the project for a few of the following reasons. The receiver is frequency synthesized, relatively low in cost (about $229 each at the time of this post), respectable in performance and fairly straight forward to interface. Hamtronics normally requests the frequency of operation at the time of purchase so the receiver arrives pre- tuned and ready to interface after mounting. Having an original Hamtronics Equipment box from a previous project I drilled the proper locations for threaded standoffs at the receiver PC-Board corners. The volume and squelch controls extend through the front panel and are normally accessible with the repeater in operation. There are pro and con reasons for leaving controls accessible to magic fingers. New old stock (NOS) Com Spec TS-32 CTCSS (PL) tone boards are very nice Ebay sleeper deals. Using one of the available sub audible CTCSS tones validates the TS-32 unit for use in this type of repeater performing 3 different functions. If you need a CTCSS tone not available with a TS-32, try looking for a TS-64 or similar easy to use Tone Board. Repeat Receiver audio is routed through the TS-32 on-board CTCSS tone filter to provide fairly clean filter flat audio output to your external controller. The repeater audio source connection point from the receiver provides De-Emphasized flat audio with CTCSS present. The output of the TS-32 tone filter section (to your external repeater controller) is De-Emphasized (relatively) flat audio without CTCSS. Connect the Hamtronics R302-6 repeater audio output direct to the TS-32 tone filter input. Don't panic, the TS-32 also provides a separate tone generation encoder section for your transmitter CTCSS requirement. A shielded audio quality wire is routed out of the receiver box to the transmitter board at the proper CTCSS connection point. After levels are properly set, you need not worry about transmit CTCSS. Of course a third section of the TS-32 board provides CTCSS (sub audible tone, aka PL) detection. The Hamtronics R302-6 Receiver provides a connection point from the discriminator to the TS-32 decoder input. The first transistor switch Out-1 is active low and JU1 JU2 or normally removed (opened). Don't forget to ground the TS-32's Mic Hangup lead to enable the decoder function. Diagrams for the TS-32 with instructions are easily found on the web using Google. The Hamtronics Receiver COR/COS output is active high, which I don't like one bit. So I simply routed the receivers COS/COR Output logic line through a 120 ohm resistor to the gate of a 2N7000 FET (also known as a VN10K and similar device). The FET source lead is grounded and the drain output lead becomes the main active low logic output source routed to your external repeater controller. DB-9 Connectors are very popular with repeater builder types. I for personal preference and experience tend to move away from using them in for this type of repeater chassis through hole connections. I have returned to using through hold feed-through capacitors and while the value is not ultra critical, you don't want the capacitance value large enough to impact the information passing through. I found and used surplus 100pf (pico farad) feed-through capacitors although I'm sure higher values will work. In my opinion the 100pf value is enough to bypass troublesome stray RF, but not greatly impact or modify the audio information passing through to the external controller. A square pattern of 3 X3 feed through capacitor holes was drilled in the back panel. I also included solder lug ground connections on some of the mounted capacitor bodies, both inside and out. Through any choice of the 9 available feed-through capacitors: 1. Repeater Audio, gated on/off with squelch, De-Emphasized and CTCSS filtered. Level is fixed at what you get, which is not a problem with external repeater controllers with adjustable input controls. This tone filtered audio is taken direct from the TS-32 tone filter output pin. The input to the TS-32 tone filter circuit on the TS-32 board. 2. Carrier Squelch COS/COR active low logic (connection is grounded with the receiver squelch open/on. I wired a 2N7000 fet drain lead directly onto the feed-through capacitor lead (chassis inside) and adjacent ground lug receives the fet source. The receiver COR/COS logic output wire arrives at the fet gate through a series 120 ohm resistor. The
Re: [Repeater-Builder] 440 Repeater Project
You simply use your own call sign, or the club you represent if you are the trustee for same. it is not like the early days of ham repeaters where one had to license it separately. I have used a club license, and presently use my own call sign. A bit more research on your part, especially the rules may be in order.

I have always used small diameter coax for my audio leads, as I have a lot of it around. I remember a discussion about audio wire in the past. Is there any problem with using coax for audio? Capacitance, maybe? I've always had this question in the back of my mind. 73, Joe, Kike

Before this gets out of hand, allow me to state that my post mentioning TASMA in conflict with SCRRBA was in error, and I posted a retraction. The potential conflict is between SCRRBA and NARCC; TASMA is not a party to the low in/high out versus high in/low out issue on 70cm band plans.

RE: [Repeater-Builder] Re: TASMA 70 cm band coordination
Guys, I really don't care to hear about your issues with the coordinating body and who likes or dis likes Shorty and his system, if you really know him he is a very generous person. Let's be done with this. I would hope that Skip and others would agree this thread is not about building repeaters or trying to figure out how to build one. No dis-respect, but you guys should keep the coordinating board business to internal email. It does not look good when everyone all over the world sees how the coordinating body acts like.
