Produced by the GPO Film Unit. Models are used to demonstrate the working of a teleprinter. Shown is how the pressing of a key on the keyboard generates a five unit teleprinter code, is then transmitted as a serial code to the teleprinter line and finally is decoded to select the correct character on the type wheel of the printing mechanism of the receiving teleprinter.

eBay find: Mullard Meteor 600A

Mullard-Tube-Radio-Bakelite-1Many thanks to SWLing Post reader, Monti, who knows that I have a serious affinity for 1940s era receivers. Monti writes from his home in Australia:

I had to send you this link Thomas. I’ve never seen this model before but what a stunning shape for a 40’s piece.

Look at this on eBay:
Mullard Meteor 600A Vintage Art Deco Bakelite Valve Radio c.1947

Lovely! While I could never pay $485.00 AUD for a non-working radio, I can certainly appreciate this gorgeous and unique design with radiating speaker grill louvres.

Check out this beautiful “meteor” dial:

Any lucky SWLing Post readers in Australia or New Zealand own one of these Mullards?

Phil’s initial impressions of the Degen DE27

Degen-DE27

Many thanks to SWLing Post reader, Phil Ireland, who comments:

I’ve just received my Degen DE27 from China. Interesting little radio, I haven’t had a good chance to put it through its paces yet but my initial impressions are the radio seems well built and fairly intuitive to turn it on.

However, all the instructions are in Chinese so luckily there was someone in my office who could set the language to english otherwise, setting up the radio is a nightmare! I will have to take the radio outside to test its performance as the office environment is useless to listen in.

The box says the radio tunes from 3.2 mhz to 21.850 mhz however, I havent been able to work out how to make it tune out of the standard SW Broadcast Bands yet. Toggling between 10 khz and 9 khz steps for AM is easy as it setting the FM band coverage but I’m yet to determine the SW settings. It appears tuning is only in 5 khz as well on SW.

As for venturing into MP3 settings and recording, I’ll leave that, it seems too much of a challenge! The clock and calendar, sleep timer, alarms are all fairly straight forward but there is an “E-Book” setting which defies description! It has a USB flash disc function and inputs for a micro SD card. Charging the supplied Lithium battery is via a supplied USB cable.

The display is easy to read and attractive with excellent backlighting. I’m not expecting stellar performance on any band, after all, it was a cheap radio (about 40 AUD with free postage) but it is built around DSP architecture. Only a single bandwidth is available and there is no SSB capabilities. The radio hopefully will be ideal to throw onto a backpack or pocket as a travel portable.

If DEGEN read these comments, perhaps an English manual put online would be extremely helpful to allow users to get the most out of the DE27.

I’ll comment more on the performance later but for now, the radio shows promise.

Thanks so much for sharing your initial impressions, Phil! Please keep us informed as you discover more about this little radio!

This reminds me that I have yet to put my Degen DE221 through the paces. Stay tuned!

Dave reviews the Yaesu FT1XD

Yaesu-FT1XDSWLing Post contributor, Dave Zantow (N9EWO), has completed a review of the Yaesu FT1XD (FT1XDR) “System Fusion” Digital-Analog Handheld Transceiver.

The FT1DX 2 meter/440 HT provides both analog and digital communications on both bands with up to 5 watts. It also has wideband receiver that covers from 500 kHz to 999 MHz (US version, less cellular) including the AM and FM broadcast band. It even has a built-in ferrite bar for mediumwave/AM reception.

What does Dave think?

Historic Ocean Gate antenna field may be removed

GoodLuckPointMany thanks to SWLing Post contributor, Ulis K3LU, for sharing the following story from newsworks.org:

Pole removal project planned for Good Luck Point tidal marshlands

The iconic poles emerging from the tidal marshes in Bayville’s Good Luck Point may soon disappear if a federal plan clears a historic preservation hurdle.

A plan funded by the federal Disaster Relief Appropriations Act of 2013 calls for the removal of hundreds of poles along with cables, wires, metal towers, and concrete blocks that sit within Barnegat Bay marshlands at the foot of the Toms River.

“The goal of this action is to enhance coastal marsh habitats by increasing marsh resiliency from impacts of large storm events and other ecosystem stressors,” according to a U.S. Fish & Wildlife Service release.

The poles are a component of inactive shortwave antenna fields associated with AT&T’s ship-to-shore shortwave communications system, which was in operation at the sites from the early 1930s until 1999, according to the release.

The area also includes a shortwave transmitter building and antenna field. Under the call sign “WOO,” the station helped broadcast Voice of America around the globe after 1944 and enabled communication with ships at sea throughout the twentieth century.
