443.85 is the TARC UHF linked system - go to www.w5ias.com for a map of all the repeaters in the system (with their status). NWS uses it to talk to stormspotters in the field for any weather event.

If the storms are in the "immediate" Tulsa area (including surrounding counties, but not (for instance) when they're off by Grand Lake then they also man the second desk, usually on 146.88. TAEMA takes damage reports at the EOC on 146.94. If either VHF freq has a problem, backups are 147.39, 147.045, and 145.11 (pretty much in that order).

In some cases, 147.045 may be "simulcasting" the UHF side, but that link is one way (receives from 443.85, but if you transmit on 147.045's input, it's only repeated locally - not re-transmitted over the UHF system.

Most of the 2m freqs (outside those already mentioned) will either be the local repeaters the outlying EOCs use to talk to spotters without UHF capability - the EOCs then relay the reports through the UHF system. The VHF freqs in Tulsa (and some that aren't) aren't really "weather" freqs - they're just local Ham repeaters (and the list provided in the earlier post is far from complete) - they may or may not have weather related traffic on them. Some most definitely will - used by outlying EOCs (147.06 in Prior is used by Mayes Co. EOC, 147.24 in Tahlequah by Cherokee Co. for example) for "relay" purposes. Others normally won't (146.805 is a TRO repeater, but its coverage is limited, so it's down about #6 on the "backup to the backup" list. Doesn't mean it won't be used, just that it won't be used "all the time".

Also, the ones that are regular amateur radio repeaters or simplex freqs (that would be all 144-148MHz and 440-450MHz) will be used for "normal" amateur traffic (whatever that is) when there is no active weather.

The last few events in the Tulsa metro have been 443.85 and 147.045 linked together. I guess 88 is not 100% and 94 is still down?

That is my understanding. However, TRO seems to be aware of the problem but as with everything, finding time and resources to fix the problems are sometimes tricky. Upkeep of the .94 machine gets blocked by the tower owner at times. Some of the .88 issues will involve some tower climbing and also some instalation of some new repeater packages. I'm confident that things will get better soon. I also think it'll take more time than most folks want or realize to accomplish.

To add what 2B said - 94 is "intermittent". The power supply crowbar (overvolt protect) trips it off if nearby lightning puts a surge on the line. Cycling the power resets it, but that can't be done remotely. However, if the whole tower loses power, 94 comes back up when the power does.

Unfortunately, that means it's unreliable when you need it most - the lightning with the storms is what gets it when we need it most. For the time being, listen for the EOC on 147.39 if 94 is not there, and TARC will be linking the one-way to 147.045 from the UHF side when the storms are close. The "fix" for 94 is ready to go - once they can get up the tower.

88 is much better with the north receiver installed downtown.
