The 442.000 at Mannford will move to 442.8 soon. This will still be part of the TARC Supersystem and will still be accessed using an 88.5 PL Tone. The reason given is that many of the Chinese made transceivers, for example Baofeng, have a receiver birdie right at 442.000 MHz. Making it difficult to tell if the frequency was actually in use. Since the Supersystem is used for Skywarn and ARES purposes, it is important that everything works properly. 442.8 was very clear at those coordinates in Oklahoma, and we received clearance for the change from Arkansas and Missouri.

The 145.27 repeater in Bartlesville, Washington County NE district was transferred to Johnny N5XQK. It is a Yaesu Fusion machine and will operate in digital C4FM mode only. It is linked on the Wires X network. WHile currently a local coverage machine only, it may be moving to a 300' tower on the west side of town. Note there is a local coverage analog machine on 145.27 in South Tulsa.

A small group of ORSI members got together during the OKC Ham Holiday 2017. Since the turnout was small and our president Duane KC5NID couldn't make it. Also our NE, SE, and SW directors weren't there, we just held some informal discussions.

1. We want to stick with the format of alternating the site for the Fall meeting between the Enid Hamfest and the Texoma Hamarma in alternating years. Therefore, this years meeting will be at Ardmore during the Texoma Hamarama during the last weekend of October. (We might have an ORSI interest table at Enid, but no meeting this year.)

KE5GLC 443.975 Ada PL 114.8 is now fully operational according to the Pontotoc County Amateur Radio Association.

N5KNU 442.5 in Edmond (OKC District) is now a DMR repeater Color Code 1, on a 400' tower should have great coverage.

W4NFD 443.125 in Porum another new DMR machine linked into the Chicago Land C-Bridge, which has many repeaters on it, Color Code 1. Right now only about 80' HAAT, but the trustee says he is trying to get a taller tower for it.

We received kind of an unusual request from a Mr. David Huntz NH6SM of Jones, OK. He is proposing a simplex calling frequency of 147.525 MHz, for users of the C4FM mode. If you are not familiar with C4FM, that is a digital voice mode promoted primarily by Yaesu, but there are other manufacturers that make equipment capable of operating on this mode. Yes digital audio is authorized in the two meter band by the FCC. Although the VoIP modes such as D-Star, DMR, P25, as well as C4FM are much more used on 70 CM. According to Mr.

The W5IAS repeater near Guthrie will move from 443.25 to 443.925 MHz still with an 88.5 PL tone. The change was fully approved on 3/21/2017, and will be made on or about 3/25. The move is being made due to some harmful interference they were experiencing on their input frequency. There seemed to be some unlicensed operators talking to each other on the input frequency. The control operator Dan K5FVL said he was not sure if they were even aware they keying up the repeater. The unlicensed operators are believe to be in the Guthrie area, but the machine is on a four hundred ft.
