The 2020 Green Country Hamfest, ARRL Oklahoma Section Convention will be held April 10-11 2020 back at the Claremore Expo Center. 400 Veterans Parkway in Claremore, Rogers County. Claremore is about a 20 min drive NE of Tulsa. Prize package yet to be determined. Last year we sold completely out of flea market tables and dealer booths. So we plan to try to add some more tables. Registration will open by mid-January. Admission prices will be same as last year $8.00 in advance and $10.00 at the door. Commercial Booths $50.00 each and includes admission.

Some Surrounding States Starting to Put Repeaters on What Were Simplex Frequencies

We've recently received some clearance requests from AR and I believe MO to clear repeaters on frequencies like 145.45. Which have traditionally been used for FM simplex. I believe they are using these frequencies for some of the digital audio modes, such as DMR. They might be simplex DMR hot spots, since 145.5 to 146.0 is reserved for amateur satellite operations. Otherwise they may be using a + offset. I'm not sure how this works.

W5HTK 145.29 On the Air From New Site

The Enid ARC moved their 145.29 machine to a 250' tower located near Goltry, OK. northwest of Enid. Solid mobile coverage from Harper Kansas on the north, to south of Watonga, to Waynoka on the west, and east to Ponca City. May be usable in Perry for mobiles. The PL tone is 141.3.

TARC's 442.000 @ Mannford in Tulsa District to change frequency

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.

145.27 Repeater in Bartlesville Changing Trustee

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.

Discussed at the ORSI Summer Meeting during Ham Holiday 2017

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.)
