145.270 Operational For Testing


This past Saturday, we enabled the 145.270 and did not hear it act up, so we have left it turned on.  Please try it out and see if it acts up for you.  If so, you will hear the squelch hang open after a person talks, and it generally sounds like some type of digital data.

E-mail myself, KB0NHX, direct at kb0nhx@nixahams.net if you see it is having problems.

Thanks for your help!

February Club Meeting A Blast!

With close to 30 people present, last night's club meeting was standing room only as we began our 3-part series de-mystifying ham radio repeaters.  At last night's meeting, we discussed how the FCC defines a repeater, some of the general differences between repeaters on different bands, and we gave a general overview of all system components normally used.

We then broke off into a hand's on session with our laboratory repeater, a Tait T800.  We discussed the process of setting up the repeater, getting software and programming cables, and some of the general alignments required to make the repeater work.

By the end of the meeting, the T800 repeater was now on our new lab frequency, and we confirmed the transmitter was on frequency, making proper power without harmonics and checked receiver sensitivity.

Next month, in part 2 of the series, we will be discussing the SCOM 7330 site controller in depth and the TX RX duplexers and interfacing both components to the Tait T800 repeater.

At the conclusion of the series, we will have a working ham repeater, and users will get to try it out at the March meeting.

Nixa ARC Club Meeting Tonight at 6 p.m.


It's winter - and we invite you all to get out of the house and to come enjoy the club meeting tonight at 6:00 p.m. at the Nixa Fire Station located at 711 N Main St in Nixa.  

Tonight is the first of a 3 part series titled "Demystifying Ham Radio Repeaters".  We will be discussing what a repeater is and do an overview of all the major components tonight, then have a practical demonstration of setting up our "Labratory" repeater, a Tait T800.  This series will not only show you some of the details of how our technical group builds our repeaters, but also allow you to see some amazing test equipment that most amateurs will never get to see or use.

We will build on this month's presentation over the next couple of months as we work our way up to Field Day, which will be discussed in short tonight as well as we make a decision on whether to reserve the white mobile command post or not.

145.270 Repeater Remains Shut Off

Due to ongoing interference, the 145.270 repeater remains out of service and shut down.  Jeremy Tannehill, KC0UJZ, part of the Nixa ARC Technical Committee, and James Adkins, KB0NHX, spoke recently about a new microwave dish that has been installed on the tower.  Jeremy is familiar with this type of dish and it is known to cause broadband noise problems due to the microprocessor.  As of now, we do not know who the dish belongs to, but it is mounted to the Verizon pod mount atop the water tower without permission from Verizon.  Currently, they are making official inquiries as to who the dish belongs to since it is also interfering with them re-positioning their antennas..

We hope to know more sometime in the following week.  Thanks for your patience as we try to sort out this issue.
