Welcome to the KG4MRA Metropolitan Repeater Association (MRA) Site

The Richmond area 224.42 repeater, formerly W4MEV has been donated to the MRA.

Operation will continue exactly as it has been in recent years.

AllStar network connections remain (on TOD basis).

The ONLY change is the call sign, which is now KG4MRA/R

The Metropolitan Repeater Association, MRA, is a group of Amateur Radio Operators dedicated to providing a high quality, wide coverage area two meter repeater for the Richmond Virginia metro area and surrounding counties. The MRA is not a club, rather, it's an association of people interested in ensuring the repeater remains maintained, supported and most importantly, used!

The KG4MRA repeater transmits on frequency 145.430 MHz, with -600 KHz offset uplink, and requires a CTCSS tone of 74.4 Hz on the uplink. The KG4MRA is now operating with Yaesu DR-2X repeaters, and therefore APCO 25 (P25) is no longer an available service on the repeater. Currently KG4MRA is operating in split Fusion mode, C4FM or NBFM Automatic Mode Selection (AMS) on the uplink, and NBFM only on the downlink. This split mode of Fusion service allows for NBFM (Analog) only radios to hear all traffic and communications when receiving KG4MRA, and use of 74.4 Hz CTCSS Tone Squelch (to block C4FM on the downlink) is no longer necessary.

The repeater transmits a CTCSS tone of 74.4 Hz on the 145.43 MHz output, to enable using 74.4 Hz RX tone squelch on users radios to block whatever noise and interference they may experience receiving the 145.43 MHz downlink. Use of the 74.4 Hz RX tone squelch on users radios is optional. The occurrence of interference on 145.43 MHz in central VA is rare, but there is a repeater in the Washington DC area running full Fusion on 145.43 MHz, and occasionally propagation will cause that repeater being received in the Richmond area.

The vast majority of users of KG4MRA use analog NBFM. But there are a significant number of hams in the Richmond area with Yaesu Fusion mobiles and HT's, so there may be more C4FM traffic on the repeater, versus the very low usage of P25 when that was supported.

The KG4MRA repeater was located on the WRLH Channel 35 Analog TV tower in north Chesterfield County (intersection of Routes 288 & 60) from 1982 to 2016. Original call sign of the repeater was W4SQT (Trustee Rod Kieper W4SQT/SK). In 2014 the call sign of the repeater was changed to KG4MRA. On December 28, 2016, the entire KG4MRA repeater was moved to its new location on the WTVR TV Channel 6 tower, when the old WRLH Channel 35 TV tower was scheduled for demolition in 2017. The WTVR TV Channel 6 tower is located in central Richmond (intersection of I-195 & Broad Street), ~13 miles ENE of it's prior location at WRLH.

The KG4MRA antenna at the new WTVR site is a Sinclair SD-224, 4 bay stacked folded dipoles, centered on 730 feet AGL, on the north tower leg of the WTVR tower.

The Metropolitan Repeater Association owes it's continued operation to the gracious hosting of WTVR TV CBS6, on the iconic free standing 849 foot AGL (1053 foot ASL) tower erected in 1953.
