Berkeley, CA (PRWEB) July 8, 2006

On Saturday, July 15, the California Historical Radio Society (CHRS) will be holding its annual “Live! At KRE” public event on the grounds of the old KRE radio station building near Aquatic Park in Berkeley.

Although thousands of Bay Area commuters pass by the old radio station every day — you can’t miss the 400-foot tower off Interstate 80 at Ashby Avenue — only a few have had a chance to look inside. Now, CHRS has renovated the nearly 70-year-old building into a broadcasting museum, filled with vintage radios, televisions and studio equipment, as well as a working amateur radio station, radio repair shop and broadcasting library.

Bay Area radio legend Carter B. Smith (KSFO, KABL) will host the event, which will run from 10 a.m. to 3 p.m. on July 15. Also on hand will be members of local radio’s famed Broadcast Legends (http://www.BroadcastLegends.com) plus live bands, an auction and flea market featuring antique radios, tours of the KRE building and an Edison Cylinder concert. Admission is $ 5 for adults; children under 12 are admitted at no charge.

For the record, the old KRE building continues to house the transmitters for two local AM stations, and George Lucas filmed the scenes featuring Wolfman Jack in “American Graffiti” at the station.

CHRS President Steve Kushman, who spearheaded the KRE renovation project, is available for interviews, photographs and media tours in the week leading up to the event. In addition to his role with CHRS, Steve is a news editor at KGO-TV (Channel 7) in San Francisco.

Winter Park, FL (PRWEB) March 21, 2006

Studio1AProductions, the media umbrella enterprise for PodSqod.com and HamRadioCast.com has just opened a modern broadcast studio exclusively for Podcasting in Downtown Orlando.

Managing Partner for Studio1AProductions, Mark Jensen says “I envisioned a fully equipped studio that would surpass the technology of even a traditional broadcast environment. …Studio1A has lived up to that challenge.”

Jensen continues, “Being a full-time Podcaster meant a new level of dedication and that dedication shines in Studio1A. As I do my daily PodSqod Morning Edition show, I wanted to take Podcasting to the next level.”

From the new Auralex Tile product featured on “Extreme Home Makeover”, to triple redundant digital mastering recorders, exclusive use of Heil PR-40 microphones, and both vocal/broadcast processing provided by Aphex, Symetrix and Orban, Jensens Studio1A contains the ‘best of the best.’

What is next for the Studio1A Media Enterprise? Jensen explains, “While Studio1A reflects the ultimate in broadcast dedication to Podcasting, my next project takes a different turn. I’m not abandoning the high-end trend for Studio1A, but I do want to offer a high quality audio experience for those that are not able to make a Studio1A type investment. The next move is one I can’t fully divulge at this time, but I will say that the goal is in line with the very principals of Podcasting. …bring quality audio means to people and they will provide the content”

Austin, Texas (PRWEB) August 01, 2013

Averna, an industry-leading developer of test solutions and services for communications and electronics device-makers worldwide, announced today the availability of RF Studio for National Instruments Software Defined Radio Platform (USRP), converting the USRP into a portable and cost-effective RF system for the recording and playback of real-world GNSS signals.

National Instruments USRP is an affordable, PC-hosted platform used with NI LabVIEW system design software to build powerful wireless communications systems for research and education. RF Studio is Averna’s proprietary software platform designed to streamline work with real-world RF signals. It provides user-friendly modules for capturing, processing, analyzing, archiving and playing back RF spectrum while also maintaining the signal-recording context.

Working together, Averna and National Instruments teams developed RF Studio for the USRP, an innovative and portable solution to record and play back live RF environments to accelerate RF project work. RF Studio’s LabVIEW compatible plug-in support delivers great value to LabVIEW users as it gives them quick access to a rich toolset for their in-house applications, and supports additional capture sources and customized views.

“RF Studio for the USRP is the only cost-effective and portable product on the market that offers the flexibility to cover a wide variety of use cases, thus making it a very competitive solution for general-purpose RF record and playback,” commented Brendan Wolfe, Director of Market Development for Averna. “We’ve been working very closely with the NI teams to bring this innovative solution to market, and we expect great success from this solution partnership.”

RF Studio for the USRP features:

Record and play back real-world RF signals, up to 40 MHz wide
Capture actual RF spectrum like FM, DAB, GPS, GLONASS, and cellular
Visualize and record weak signals with the Noise Figure view
Advance signal analysis with the Spectrum, Histogram, and Power views
Use simple RF-chain configuration tools to quickly detect and set up the recording environment
DriveView option: Log video, audio and NMEA data at the same time as recording RF

Click here for more information about RF Studio for the USRP.

“The combination of RF Studio and the USRP provides a flexible, affordable solution for RF record and playback. Now in addition to prototyping wireless communications systems in LabVIEW, users can test them by reproducing realistic RF environments in the lab,” said Erik Luther, Wireless Communications Group Manager for National Instruments.

Pricing and Availability

RF Studio for the USRP is available now to customers worldwide through National Instruments’ LabVIEW Tools Network. Contact us at sales(at)averna(dot)com for complete details.
