Huge Tracking Dish to Become Available for EME

Read by: PAUL KJ4WQN

The InfoAge Science History Museum in Wall Township, New Jersey, plans to make a 60 foot tracking dish antenna available to hams for moonbounce, secondary to its function as a radiotelescope. It was on the InfoAge site, then part of Fort Monmouth, that the US Army’s “Project Diana” team in 1946 first received radio signals bounced from the moon.

According to InfoAge’s Martin Flynn, W2RWJ, Daniel Marlow, K2QM, an InfoAge board member who teaches physics at Princeton, wants to use the dish, currently under rehabilitation after being dormant since the 1970s, to pursue radio astronomy for instructional purposes. Marlow’s primary goal is to restore the TLM-18 dish antenna to working order and use it to see the 21 centimeter radiation from the Milky Way. But he also wants to observe radio pulsars, and since that activity can be performed at 70 centimeters, the TLM-18 will be made available to the Amateur Radio community for EME at 432 MHz on a secondary basis.


The dish, adjacent to the Ocean Monmouth Amateur Radio Club’s (OMARC) N2MO at InfoAge, offers a gain of 35 dBi at 465 MHz. Project Diana occupied the building housing N2MO, Flynn noted. The after-effects of Hurricane Sandy continue to hinder the dish rehab project; power on the InfoAge campus remains out since the storm last year, and the facility is running on generator power. “It has slowed down the efforts at putting the TLM-18 back into service but has not stopped them,” Flynn said, noting that OMARC members have been behind the project from Day One. It’s hoped the dish will be ready for service next year. — Thanks to InfoAge and Martin Flynn, W2RWJ, AMSAT-UK International Space

Attention ARRL Field Day and June VHF Contest Participants

Read by: ED KE4JWS

In the aftermath of recent e-mail problems at ARRL Headquarters, the ARRL Contest Branch is asking participants of ARRL Field Day and the June VHF Contest to make sure their logs have been received by ARRL Headquarters.

Visit the Logs Received page on the ARRL website, and if you do not see your call sign, resubmit your Field Day information via the online entry form or resend your June VHF Contest Cabrillo file. If your call sign is listed, you don’t need to do anything. ARRL will relax submission deadlines for a reasonable period to accommodate all who may have been affected.

For more information contact the Contest Branch.

Public Outreach with NTS Messaging


The ARRL National Traffic System (NTS) routinely passes practice messages to help operators build and maintain their traffic-handling skills. One way to create such messages is to solicit them from the public at preparedness fairs, exhibit booths and, of course, Field Day You can download a pre-formatted message form that’s guaranteed to make this process as smooth as possible. Print as many copies as you need and put them on display along with a sign inviting visitors to send a message.
Disaster preparedness for individuals and families includes having out-of-state contacts that can be notified in case of an emergency.


When curious visitors approach the table, explain the importance of having such information. Be sure to emphasize the fact that in a real incident Amateur radio m be the best way to reach their designated contacts.

The message form is easy to use. Your “intake” person simply inserts the addressee and sender information from the visitor and passes the completed form to the NTS operator, who adds the appropriate header information and sends the message on a regular traffic net.

It’s a terrific way to engage the public and it will heighten their appreciation for our disaster communication capabilities. — Clara Woll, KJ6CNO, ARRL Official Relay Station
