Moshe’s early birthday gift: a Philips 90AL765

Philips-90AL765-FrontSWLing Post contributor, Moshe, writes:

After reading your post about your Panasonic RF2200 pre-birthday present, I decided I want to do the same. The radio I chose has a story behind it…

My Grandfather had the same exact radio. I used to play around with the radio as a child, (especially with the shortwave bands, looking for number stations…). When my Grandfather died, about 23 years ago, the radio disappeared.

I decided this is the radio I want for my birthday. I could not remember the maker of the radio, nor it’s model, but I remembered how it looked.

I spent many days looking for all variations like “portable transistor radio” and so on, until I found a photo on the Internet: I was looking for a Philips 90AL765 radio.

I found it on Ebay. A very kind seller from Australia had it.
I purchased and receive the radio on the 26th of June (my birthday was the 12th of July). As soon as I got the radio, I opened it up; it needed cleaning (the case itself and the contacts).

Philips 90AL765-Back

After cleaning the contacts and washing the case, the radio runs (and looks) like new. I thought I would have to recap the radio, but it sounded perfect and without even a hint of hum, so I left it as it is.

It has the volume and tone knobs missing, but it can be operated with no problem. Sound quality is amazing (I added a video of the radio playing All India Radio on 6155 kHz)–it works very well on all bands and is very sensitive. By ear, the bandwidth sounds like 8 kHz or more. Radio bands are: MW, SW (2 bands) And FM.

The shortwave band is divided in two: SW1: 2.3MHz- ~7.4MHz, SW2: ~9.4MHz- 22.5MHz. For fine tuning on shortwave, the radio has a “Fine Tuning” control, which is a potentiometer connected to a varicap.

If you place the control in the middle (It lacks a detent spot) and tune in a station, this control will put you spot-on (the receiver is very stable).

Some info about the radio: According to Radiomuseum.org, the radio is dated to 1977, and was made in Austria (mine and my Grandfather’s were made in Singapore).

It contains 13 transistors, 3 of them are can transistors (not plastic).

Tuning is slide ruler type, and the only connection is A DIN5 for recording (wired for mono).

Philips 90AL765-Back2The radio can be operated from 4 D cells, or directly from AC (in the picture you can see the transformer). It can be operated from 230V or 120V. Note that if you move the plastic pin cover from the left pin to the right one, the center pin remains visible at all times. Also you will have to move the plastic cover piece on the back to the left.

The Ferrite is 14cm long, the telescopic antenna is 79cm fully extended, and it has an elbow joint that allows you to place the radio in your lap and still the antenna will point up with no problem. Only thing is that if the antenna is extended, the handle cannot change position since the antenna is in the way.

Philips 90AL765-Side

Width of the radio itself is 29cm (31cm with the handle and the knobs).
Depth is 7cm.
Height is 16.5cm (21cm with the handle).

All in all, it is a very fine radio and I love it!

Moshe, thanks so much for sharing your story!

Perhaps, one of the true virtues of sites like eBay is that they allow us to search the world for somewhat obscure devices that have such a strong family and nostalgic connections. Congratulations on your find!

Rob’s Yaesu FTDX3000 video series

FTDX3000My buddy, Rob Wagner, has started a series of videos featuring the Yaesu FTDX3000 transceiver. On his blog, the Mount Evelyn DX Report, Rob describes his first video:

Some shortwave listeners may not be familiar with using single sideband for receiving stations transmitting in the Amplitude Modulation (AM) mode. I have prepared a little video designed to demonstrate reception of SWBC signals in single sideband (SSB) mode. Under certain circumstances, this can be beneficial in providing better reception and more pleasurable listening in times of heavy interference (QRM).

[…]This video is the first in a short series featuring my new Yaesu FTDX3000 transceiver. You’ll get a good idea of what this rig can do by seeing it actually in operation on the shortwave bands. There are more videos to follow…..

ECSS is indeed a powerful and often overlooked tool for mitigating QRM and adjacent signal interference. Many thanks, Rob, for showing us how easy it is to use!

Though I’ve embedded Rob’s first video, above, I would encourage you to follow his excellent blog so you don’t miss future videos.

Richard’s search to find the best SWLing spot on campus

Richard-UNB

SWLing Post contributor, Richard Langley, has been seeking the perfect spot on the campus of the University of New Brunswick (UNB) to listen to shortwave. He recently shared the following:

Here’s a link to a brief video of my recording of last weekend’s VOA Radiogram “in the field” (a UNB parking lot):

Richard goes on to say that he’s found an even better location:

“That location on campus (green pin on attached image) turned out to not be noise-free on all bands. Found an even better location (red pin). Negligible power-line interference although still within Wi-Fi range of UNB’s system but no significant effects from that discovered yet. Got excellent reception of VOA’s Radiogram this past Saturday afternoon. Extremely clean waterfall in Fldigi. And virtually noise-free images [below]”

Many thanks for sharing this with us, Richard!

Those of you who live or work in areas with significant radio noise should consider scouting out a listening spot like Richard has. Also, you might be inspired by LondonShortwave who takes his radios to public parks. Regardless, moving your receiver as far away from sources of radio interference as possible will always yield better listening results.

Jack Barsky: KGB spy who relied on numbers stations

JckBarsky

Many thanks to SWLing Post reader, Anthony, for forwarding this CBS/60 Minutes video: an interview with former KGB spy, Jack Barsky. During the interview, Barsky mentions that he received encrypted KGB “radiograms” via a numbers station he believed to be in Cuba. He admitted that the messages could take an hour to copy, then an additional three hours to decode. This is a fascinating story–well worth watching.

Here is the intro via 60 Minutes:

“Tonight, we’re going to tell you a story you’ve probably never heard before because only a few people outside the FBI know anything about it. It’s a spy story unlike any other and if you think your life is complicated, wait till you hear about Jack Barsky’s, who led three of them simultaneously. One as a husband and father, two as a computer programmer and administrator at some top American corporations and three as a KGB agent spying on America during the last decade of the Cold War.

The FBI did finally apprehend him in Pennsylvania but it was long after the Soviet Union had crumbled. What makes Jack Barsky’s story even more remarkable is he’s never spent a night in jail, the Russians declared him dead a long time ago, he’s living a quiet life in upstate New York and has worked in important and sensitive jobs. He’s now free to tell his story…as honestly as a former spy ever can.”

Jeff Murray presents: Love, Death & Shortwave

SINPO-Pictures

From my buddy, Jeff Murray (K1NSS), the Mastermind behind Dashtoons:

“Created for the North American Shortwave Association’s Winterfest 2015, this unflinching documentary recalls a time when tuning a short wave radio was something akin to enjoying a schnapps in a cool West Berlin jazz bar less than a klick from Checkpoint Charley, especially if you were eleven years old.”
