New CAUHF Repeater in North Little Rock, Arkansas

The CAUHF Group has a new UHF repeater high atop the Towbin VA Medical Center in North Little Rock--perhaps the highest peak in all of the downtown Little Rock and North Little Rock area. This repeater operates on 444.700 mHz with a 114.8 PL tone and id's appropriately with W5NLR. Charlie Roberts KD5OCQ, with his professional crew from Simplex Towers, along with Tem Moore N5KWL erected a new Cushcraft 16-bay dipole on Friday, November 17th, completing this project which has been in the planning and construction stages for almost a year. The CAUHF Group is fortunate to have several professional RF engineers in our membership, making impressive projects like this one possible.

Preliminary reports tell us that you can hit this repeater from anywhere in the downtown area on 1/4 watt or LESS! Additionally, it should easily cover a 50-mile radius with a 35 watt UHF mobile. This high performance repeater is operated through a Memorandum of Understanding between The CAUHF Group and the Central Arkansas Veterans' Administration Medical Center. Aside from the remarkable elevation, Towbin VA Medical Center provides us with 24/7/365 standby power if the need should ever arise. Other hams assisting with this project over the past several months include Joel Echols N5QLC, Ron Lynch K5POG and Steven Hicks W5NLR.

New CAUHF "Porta-Peater" has been deployed in Malvern, Arkansas

The new CAUHF "Porta-Peater" has been deployed in Malvern, Arkansas as 442.225. We could not wait for the permanent machine to be completed because we were anxious to put something on K5RQO’s newly erected 125’ tower. 442.225 is permanently linked to CAUHF’s 443.200 machine in Little Rock.

On Thursday, November 2nd, Charles, Tem N5KWL, Gene K3IC and Ron K5POG hauled the “Porta-Peater” to Malvern in the back of a pick-up truck.

Tem N5KWL had previously installed the equipment from the former 444.850 machine in a 4' rack complete with wheels—and thus the “Porta-Peater” was born and appropriately named by Charlie KD5OCQ. It has been temporarily re-tuned to 442.225 mHz for the Malvern project while a permanent machine is being built. Pictures of the “Porta-Peater” and K5RQO’s tower can be seen on the Flicker string on the right side of this page. Matt KE5HLH and Joe N5IOZ also stopped by and helped out with the project.

Initial CAUHF Constitution Adopted

The first CAUHF constitution was adopted by unanimous vote at the last quarterly meeting held Thursday, October, 19th 2006 at Shotgun Dan’s Pizza in west Little Rock. We’re now official! Our next task is to officially register with the ARRL.

Holley Mountain 442.000 now permanently linked to 443.200

Jim Collom N5YU has worked hard these past few weeks to establish a new dedicated link between the 442.000 (82.5 PL tone) machine on Holley Mountain and the 443.200 repeater in Little Rock. The Holley Mountain System consists of several repeaters located just north of Clinton, Arkansas on US 65 and covers a large portion of north and northeast Arkansas. This new, dedicated link now enables one to talk on the CAUHF system all over north central Arkansas. For more about the Holley Mountain System click here.

Charlie Roberts KD5OCQ installs the 443.200 machine on Shinall Mountain

This is its permanent home. The Alexander and Sherwood remote receivers are up and running and the VHF and UHF secondary inputs are both working as well. RBI commissioning and antenna upgrades will be occurring shortly. We appreciate everyone’s patience.

The K5POG 443.000 repeater has been switched to an ultra-rugged Motorola MSF 5000

The existing machine will be retuned to 444.700 and will carry the W5NLR call sign and be deployed in North Little Rock as soon as a location is available.
