Pearl Harbor Day Memorial Crossband Operation From Battleship IOWA’s NEPM
With operating authorization from the Navy’s 3rd Fleet Spectrum Manager, Battleship IOWA Amateur Radio Association, Inc. and the IOWA’s Innovation and Engineering Team will activate the ship’s legacy Navy call sign, NEPM, on December 7, 2021 in memory of Pearl Harbor Day. Operation will be from 1600 to 2359 UTC.
NEPM will TRANSMIT on 14781.5 KHz using J3E USB and listen on 14343.0 KHz J3E USB. Amateurs are reminded that they may NOT transmit on 14781.5 KHz. If there is traffic on 14343.0 KHz, the NEPM operator will advise of an alternate frequency where he is listening.
QSL’s will be available if a SASE is provided. NEPM, NI6BB. or NE6PM are all listed on QRZ.com and any route will get your request to the QSL manager. Please visit BIARA’s website at https://biara.org for more information about radio operations aboard the Battleship IOWA soon to be the home of the National Museum of the Surface Navy.

- In process – a remote station operating project in the works. Check back for more info.
- BIARA now has NI6BB/R switched to running low power on 147.975 MHz, -600 KHz , 88.5 Hz PL. The repeater is on the 010 level of the battleship and the antenna is on a yardarm at 013. We had hoped to be coordinated by TASMA to stay on this frequency pair but was advised otherwise this month. We are continuing to seek another pair and will strive to minimize QRM to a coordinated operation on 147.975 in the mean time. We plan to add AllStarLink and Echolink nodes to the machine in the future. In the mean time, check it out and report back to W6HB and WA6MEM with comments or questions.
The Battleship Iowa Amateur Radio Association (BIARA) is an association of radio amateurs whose purpose is the support of radio activities on, or associated with, the Battleship Iowa. The operation of the Battleship Iowa is under the control of the Pacific Battleship Center (PBC), a 501(c)3 non-profit California corporation. BIARA is a social and recreational non-profit 501(c)7 California corporation. All BIARA full members who engage in amateur radio activities aboard the Battleship Iowa are required to be accepted and registered as volunteers of the PBC and to abide by all volunteer guidelines and directives as may be established by the PBC.
BIARA acts as the representative of the Battleship Iowa, the Pacific Battleship Center and the National Museum of the Surface Navy within the amateur radio community; in this role, BIARA promotes the Battleship Iowa, the Pacific Battleship Center (PBC), the National Museum of the Surface Navy, the interests and advancement of amateur radio, coordinates the activities of the associates in providing public service and provide the opportunity and facilities for the gathering of associates and others interested in the hobby.
BIARA operates its station under license NI6BB from the communications center on the Battleship Iowa promoting the PBC, the Iowa and amateur radio in general. We appreciate your contacting us and helping us in our mission.
BIARA does not solicit donations for its operation. Persons wishing to make tax deductible donations are encouraged to do so to the Pacific Battleship Center (PBC) as our host. The PBC is dependent on grants, donations, ticket sales and event income to maintain and enhance the battleship. Your help for the greater good is appreciated.

NEPM was the Iowa’s call sign from her initial commissioning in 1943 until her final decommissioning in 1990. In 2002, it was assigned to the USCGC Heron. In 2016, through efforts by Bob, WB6SLC, the battleship was able to have the call sign reassigned. The USCGC Heron now has NHRN. The Iowa is one of the only US museum ships that has it’s original military call sign assigned.
Having the call sign does not afford any operating authority, although once a year, BIARA may use the callsign NEPM during the annual Armed Forces Cross-band Tests if authorized. The ship’s quarterly activation of the “Gray Radios” is under the Innovation & Engineering Technology’s call sign NE6PM for which Gary Lopes, WA6MEM, is the trustee.
Each station contains an Astron RS-60M Linear Power Supply with an Icom IC-7300 HF Transceiver paired with a laptop for logging and digital modes. We have three identical stations that may be tied each to one of three possible antennas.
Station operator in the photo is Roy, 4X5IQ.
The discone-cage antenna in on the bow. Two antennas, each with a separate feed point, are combined in one structure. Higher bands use the discone, with the radial elements at the top as the disc and the upper section of the cage as the cone; feed point is the gap between the disc and the apex of the cone. The lower bands, fed from the bottom, use the entire cage section.
A trussed monopole is mounted above the Aviation Service Center on the aft deck. This antenna covers 10-30 MHz. The red base identifies this as a transmitting antenna (blue bases denote receiving antennas). The nonskid deck in foreground is for the flight operations area. Three hooded signal lamps are along the aft edge of the hut roof. At left is the No. 3 16-inch gun turret.
