Repeaters and Nets

The Calvert Amateur Radio Association operates three repeaters that serve amateurs around the Calvert County area.  The 146.985  repeater is located in the northern end of the county in Sunderland, Maryland.  The 444.950 repeater is located in the central area of the county in Prince Fredrick, Maryland.

The repeaters can be linked to provide good coverage of  Calvert County and the surrounding area.  When the repeaters are linked, a transmission from the remote repeater has a two tone courtesy beep following each transmission.  A transmission originating through the local repeater will not have the courtesy beep.

On March 9, 2020 a new 2 meter antenna was installed at the 6th floor level of Calvert Medical Center.  Repeater testing will start soon.  Stay tuned.  Currently the 440 machine is operating from Sunderland and the 2 mtr machine from Prince Frederick.

DMR REPEATERS

Two new DMR repeaters have been setup by N3PPH to cover southern Maryland, one in Mechanicsville covering southern Calvert county and one in Sunderland covering northern Calvert.  These repeaters also supply coverage to parts of St. Mary’s, Charles and Anne Arundel counties. The Sunderland site is using the clubs dual band antenna, the Mechanicsville site is on the same tower as the 147.195 repeater. Some club members are already using DMR and all are welcome. All of the information about available  talkgroups, nets, other local repeaters and a good description of DMR can be found at http://delmarvadmr.com.

6 METER REPEATER

The repeater was set up for all hams to use it is an open repeater this means it can be used at any time by anybody for any situation.

The frequency is 53.170 megahertz receive. An the transmit frequency is 52.170 megahertz . with the offset is minus with a PL tone of 100.0.

There are no formal nets on this repeater but every morning between 8 AM to 10 AM you may find someone to talk to.

Please take a few minutes and look at the YouTube video https://youtu.be/up5A_57u2kg    It shows you the repeater and how it’s put together nothing fancy just a bunch of parts put together to make a repeater system.  The receiver is at Shawn’s house N3AE and the transmitter site is at Bob’s house N3PPH.

In the future: I have a receiver voter this means I can have more than one receive site. I can have several I am always looking to put up more receive sites.

The transmitter covers the county very well. I have been south and north I here it from my mobile very well but I do need more receiver sites
