New World Record On 10GHz:
A new world record in distance on 10GHz has been established between the Cape Verde islands and southern Portugal. On 10 July at 10:46 UTC the previous record of 2070km was smashed by a SSB QSO at 2696km during the Hyperatlantica 2010 DXpedition. A detailed report will appear in the September 2010 RadCom but in the meantime details, in French, can be found at www.hyperatlantica.ch. Congratulations to all involved.

Radio Days: One Man's Collection Lives On:
Radios were the late George Helmer's passion. The older the better. Taking in his radio collection in the Riverside home where his widow lives transports one back to those early radio days when families gathered around to listen to the Ozzie and Harriet show, Bob Hope or Fred Waring, or heard the deep, far-off voice of Edward R. Murrow broadcasting his vivid accounts of the London Blitz during WWII . "All of us growing up listened to those little radios in our bedroom," says Robyn Helmer, George's widow. "There was something so magical about it. Signals coming through the air that you couldn't see coming to your house. It was so much more fascinating than television. It was miraculous." Robyn is now custodian of George's collection. There are radios -- big and small and in all styles -- on display in numerous rooms of her house, including the basement. "We went to some of the strangest houses to look at radios," Robyn says, recalling her husband's collecting days. There were the radio swaps up in Nashua, N.H. and the more upscale haunts in New Haven, where they found art deco radios. "I carried the money," she says. "The people who were buying were interior decorators for stores that would resell them for enormous prices. George said he never paid more than $25 for any of them."

NARF!

The Lab RATS section is the venue for local hams to showcase some of their homebrew engineering as a way to elmer others through some of the technical aspects of our hobby.

I.C.E. engineers and staff technicians have prepared a list of free technical publications for customer reference. These cover a variety of subjects related to the usage of I.C.E. products, facility design and construction, lightning and over voltage protection, and product comparisons with other companies' goods.

 

Written in easy-to-understand language for the non-technical:  Special Publications

Easy Digital EmCom

This method of sending Data for emergency communications is the best idea I've seen ...ever.  It can be used with any operating system...Mac, linux Windows whatever  all you need is a computer and a radio ...that's it no cables nothing else.  You play the encoded message from your computers speakers right into your microphone. It can be used on repeaters or without and it is also cross platform!  It's ideal as it requires almost no training to learn how to do it! Other forms of packet etc require special cable interfaces  or a TNC and a dedicated node to act as a hub in some cases.  This requires non of that!!! It's very simple......

 

The use of the NBEMS software requires nothing more than a laptop or desktop computer and an amateur radio transciever (even an HT) to send and receive data/text using the NBEMS soundcard-based digital software.

 

This site concentrates on only a few of the primary digital communications modes available within the FLDIGI software package that are best suited to Emergency Communications.

A key to promoting the widespread adoption of digital communications is to keep the protocols as simple as possible and providing means of conducting digital communications with the use of equipment and transceivers that are already commonly used.

The NBEMS/FLDIGI software is the perfect package for digital emergency communications because it is:

- FREE!
- Easy to configure
- Easy to use
- Easy to modify and standardize
- Works on Windows XP, Windows Vista and Linux systems
- Usable without the need for additional/complex/expensive hardware

WSPR-stands for Weak Signal Propagation Reporter-by VE7REZ
WSPR - Distant Whispers ( the following is courtesy of G4ILO )

One of the things that makes communicating with amateur radio more fun than using the Internet or the phone is that you never know where your signals will be received. Short wave radio propagation is never completely predictable, and can often surprise you. If this is an aspect of radio that fascinates you, then you'll enjoy using WSPR.

WSPR is a piece of software that enables you to participate in a world-wide network of low power propagation beacons. It enables your radio transceiver to transmit beacon signals, and to receive beacon signals from similarly-equipped stations in the same amateur band. Because participating stations usually upload spots that they receive in real time to a web server, you can find out within seconds of the end of each transmission exactly where and how strongly it was received, and even view the propagation paths on a map.

If you left WSPR running while you were doing something else, you can also search the database to find out later where your signals were received during the day. You can analyze past signal reports to see the effect of seasonal propagation changes or antenna improvements.
What is WSPR?

WSPR stands for Weak Signal Propagation Reporter, but it's pronounced "Whisper" - quite an appropriate name as it is all about sending and receiving signals that are barely audible.

WSPR is a software application written by Joe Taylor, K1JT, a Nobel Prize-winning Princeton physicist. It was first released in April 2008. It uses a transmission mode called MEPT-JT. The "JT" stands for Joe Taylor, while MEPT stands for Manned Experimental Propagation Transmitter.

Joe's web site has the software to begin your adventures with WSPR:
