The repeater, not the Weird Al movie.

Please tune to 443.7000 MHz, tone 141.3, and give it a test drive.

This 10-year-newer Motorola unit was a gift from Ken, KC5OU, who found it online and gave it a new home. Controller for the unit is a Computer Automation Technology CAT-200B. Although used, it is in very clean condition.

KC5OU and your editor took it out to the site and installed it today.

While the antenna remains at about 175' AGL, the new unit puts out a little over 25 W versus the 7 W of the old unit. That should give us a little more range.

The Technical Committee solicits your feedback on the voice quality as well as range.


Stadium Remote is ON THE AIR

Ken KC5OU has refurbished the Stadium Remote and it is back in service atop the OU Football Stadium press box.

A new channel element was installed moving the input to 147.660, the same as the main receiver. To use the Stadium Remote, please use tone 100.0.

Consider the next few weeks as a "test" to make sure that all is well.


More power!

OK, not really. In fact, you'll probably need less power to reach the VHF repeater.

Thanks to Ken KC5OU, the receiver section of the repeater was recently re-aligned.

The increase in sensitivity was on the order of 25 dB thanks to adjusting some components that had changed value over time.

We've had some good reports from KE5DVB in Newalla and KD5RAK on his HT in far west Norman.


Programming your radio (repeat)

(This has been posted this before but it's worth repeating)

Your HT, mobile, or home station should have the following channels programmed into memory slots:
  • 147.0600 +600 kHz offset, transmit tone 141.3 Hz
  • 147.0600 +600 kHz offset, transmit tone 100.0 Hz
  • 147.0600 simplex, transmit tone 141.3 Hz
Following this pattern allows switching between repeater receivers with a minimum of hassles.

The repeater also passes the 141.3 Hz tone, but whether you include that as a receive tone in your configuration is up to you.

If you can set channels to be "skipped" or "locked out" on scan, you should consider doing that for the 2nd and 3rd channels above as they all carry the same audio.

Why the simplex version? Should the repeater go down completely, you will be able to talk to folks on the repeater's output frequency. This will alert others to the fact that the system is down since they may be able to hear you.

For UHF:
  • 443.7000 +5 MHz offset, transmit tone 141.3 Hz
  • 443.7000 simplex, transmit tone 141.3 Hz
Again, lockout, or skip, the simplex version so that you don't end up scanning what are, essentially, duplicate channels.


Stadium Remote

Whenever the power cycles at the Stadium, the Stadium Remote resets. That's why we've been hearing AC6GT's Echolink node coming through the repeater.

We are working on gaining reliable access to the Stadium in order to visit with the equipment which is surely lonely not having been touched in several years. If we can repair the CTCSS tone board, that should end the interference issues with AC6GT.
