Welcome to our Nation's Capital and the web home of the Network
Engineers Repeater Association (NERA). NERA was founded primarily by
amateur radio operators employed in the broadcasting and related
telecommunications fields in the Washington Metropolitan Area. We have
constructed a network of linked remote base and repeater stations in and
around the region to provide clear, long-range reliable communications and
invite all licensed radio amateurs to stop by and give our system a try. We
support SKYWARN and ARES public service
operations and we are affiliated with the American Radio Relay League.
Recent Improvements To The NERA
Repeater System
We have been working to make all the systems P25 capable. Currently all
NERA repeaters with the exception of Baltimore are capable of mixed mode
P25 and FM . Work is ongoing to link up the
repeaters on FM as well as P25.
Also late in 2012 NERA rebuilt, reactivated, and expanded the site of
its currently non-linked VHF repeater in Germantown, Maryland. Located just
off Interstate 270, this repeater’s antennas are at 390 feet and provide
excellent coverage of Montgomery and Frederick counties, as well as some
coverage into Northwest DC. Best of all, this repeater consists of two
separate systems, one being analog FM and the other P25 digital. Both
systems at this site are wideband. What you input to this repeater is what
is transmitted, but it can only handle one mode or the other at a time. The
FM analog input has a PL of 156.7, and the P25 requires an NAC of 293.
Input frequency for both systems is 147.870 and the output, again for both
systems, is 147.270. Our plan is that this repeater will eventually be
linked to the NERA UHF system but at this time (January 2013) it is a
standalone repeater. Please also note that, at
this time, this repeater is open for all to use.
NERA has moved over to Groups.io for
organization communications. If you are a member and need to be added to
the groups.io distribution site please email WA3KOK at ARRL dot net

Operating Guidelines
Good amateur operating practices are encouraged. Whenever you access the
NERA system please remember to pause a moment between transmissions to
allow others to join your QSO or to pass emergency traffic. This practice
is particularly important when accessing other repeater systems via the
IRLP or DRIL since some additional "turnaround" time is
frequently required. Don't use 11 meter lingo when talking on the system.
Speak normally.
If your organization desires to use the NERA system for a planned public
service activity please let us know as early as
possible prior to your event so the activity can be coordinated and the
system configured effectively.
