The 145.43 going from Quantar to Yaesu repeaters – needs user financial support

Reaching out from 730 feet (AGL) near the merger of I-195, I-95, and I-64 sits the antenna for the MRA (Metropolitan Repeater Association), 145.43. It is a nice complement to the RATS 146.88 repeater in the southwestern part of the metro area. 145.43 has a long reach north towards Fredericksburg, west to Mineral, east to Bottoms Bridge, and even to southern Chesterfield.

The commercial-grade Quantar repeaters with analog FM and P25 digital have finally worn out. Parts are not easily acquired. It is replacement time.

The Yaesu DR-2X analog+digital transceivers will replace the Quantars. The MRA is buying two so there is backup. It will start with analog. Once stable the Fusion digital mode will be enabled. Finally some WiresX functions will be added.

If you use that repeater, please contribute to the fund to buy the repeaters. The transceivers, the supporting LAN cards and other items will cost over $2,000. Send your contribution to:

New How to area

There is now a new how to area on the website, on the right under RARC.

Currently there are 3 sets of instructions

  • How to change your address with the FCC
  • How to renew license with the  FCC
  • How to find where Hams are in Virginia (FM17 grid, and several club’s members), and all of the Virginia repeaters. You need Google Earth to display the locations on the map.

Designing and Constructing Magnetic Loop Antennas

Two presentations, one by John DeMajo, K5HTZ, and a second by Ken Zutavern, K4ZUT, at the 10 January 2020 RARC club meeting are outlined here.

John DeMajo Mag Loop presentation

John‘s presentation is available by clicking this link: loop-antenna-project

John’s spreadsheet calculator is at mag_loop_calculator.

Ken showed another design that used a hand-wound toroid transformer instead of a small loop to feed the large loop.

K4ZUT toroid transformer and motor-driven capacitor tuning

Ken’s loop also used a motor to turn the tuning capacitor. This allows him to locate the loop away from his operating position.
