The big shack renovation meant I had to put all my stuff back into boxes. No problem spending some time without my rigs and tools, but I didn’t want to spend a couple of months without any form of radio. So I left out the RTL-SDR dongle and a mobile whip to see if I could get some more out of it than digital TV. I have had the dongle for a while now, but I was never impressed by it. Lots of white noise and very few signals to be seen on the waterfall. I even boxed it up nicely to avoid EMI.

The first step was to see if the dongle still worked by scanning the DVB-T bands. After installing the necessary RTL-SDR packages I fired up VLC to see if it would decode signals. There are packages like MythTV and MeTV that can let you watch DVB-T, but I don’t like cluttering up my system especially since VLC is such a versatile piece of software. For it to work you need to open an console though, but the internet is awash with good tutorials to help you get it done.

Step 1: install dvb-apps with sudo apt-get install dvb-apps
Step 2: use the scan application that comes with dvb-apps: scan /usr/share/dvb/dvb-t/tw-All > channels.conf
Step 3: open the channels.conf file with VLC
Step 4: choose your favourite channel and enjoy

Most of the time Linux provides an alternative and in this case it’s w_scan: w_scan -X -c TW

substitute your own country code in place of TW; a list can be retrieved by issuing the command w_scan -c ?

Before I knew it I was watching the WBSC Premier 12 baseball games and found out Taiwan’s public broadcaster is airing Person of Interest. Usually I find that watching tele is just a big waste of time, but I do also find that it is the only time I am not physically active and I do need to rest more. My wife likes PoI too, so now we have a date every Monday through Wednesday at 10.

The FM band was another check to see if the RTL-SDR dongle works as advertised. On Windows the prevalent SDR software is SDR#. On Linux this is GQRX, which is based on GNU Radio, a very powerful but complex piece of software. Before you can start GQRX you need to deactivate the dvb_usb_rtl28xxu driver as this conflicts with the rtl2832 driver. Issue the following command: sudo rmmod dvb_usb_rtl28xxu. If you never watch TV then blacklist the driver in order for it to be never loaded when you insert the dongle.

I could indeed receive FM broadcasts, but as many as I could with my Sangean ATS-909, so no big win there. GQRX also has a build in AFSK demodulator and I tried to decode some APRS signals on our local frequency of 144.640 MHz. I could hear signals and see them on the waterfall, but not decode them. After trying some other antennas and even taking everything outside in the open I grew a bit frustrated and searched for some other signals to decode. Tracking aircraft using ASD-B seemed fun (G4VXE wrote about it before here on AmateurRadio.com ) so I tried to set that up. And in doing so I got a big surprise.

A post from John Henry KI4JPL (reprinted with his permission):

Thu, 3 Dec 2015 06:12:00

I wanted to bring people up to date on what is happening right now.

I had a discussion with the new owner last night, and I wanted to relay some information.

He is now officially the new owner of TEN-TEC.

He is planning the rigs and amplifiers and other accessory products to engineer and to manufacture for the coming year to cover the purchase and expenses for the year, working on the details of the various plans for service, sales, and marketing, etc.

Don’t underestimate the amount of time and planning and effort that this business strategy planning maintaining overhead etc stuff takes.

Learning lessons from the past to help the future of the company be more viable.

What will you see? and when?

Planning on having the OMNI-VII back in production in 1st quarter 2016, hoping to ship in 2nd quarter 2016.

Dayton, He will be there, going to try to get the same TEN-TEC booth/booths as possible. Showcasing the existing products, and possibly something new based on the existing products, time will tell.

He did say that he will either bring back the Orion II or have an Orion III. Time frame is tbd. could be as early as end of 2016 or Dayton 2017????

There might be improvements/changes to certain rigs, e.g. maybe there will be an OMNI-VII+ maybe an OMNI-VIII in a year???

The Eagle will go back into production some time after the 1st OMNI-VII run.

Prices will return to the original pre liquidation sale prices when the new website is up so that each will be at a point that will make enough profit to make the company viable. Other features will get added where possible.

TEN-TEC was actually shipping a $200 bill with every one of a specific model that it sold this last year.

There were so many ways that TEN-TEC has been hemorrhaging over the last couple of years, and even back a bit further, that changes will have to be made. Some the public won’t like, but then the alternative is that TEN-TEC would close forever.

Also remember, it was made public that the two owners of RKR were looking for a new owner, and how many stood up to say “I’ll buy it/fund it/save it”. This gentleman did and will do what he has to do to keep the brands alive.

There are plans to bring back some VERY good products, items that have been big sellers for TEN-TEC just a few years ago, and were profitable and have been requested for quite some time.

Also, there are still commercial orders coming in that will be there for maybe another year or two using the same RX331/RX340 platforms that will help him maintain a cash flow that will help realize amateur market production runs. There might be a need in the future to try to raise some more capital if certain plans come to fruition with commercial and FEMA customers, if those work out, may need to raise some cash to buy the parts, so there might be a gofundme funding campaign set up, where amateur customers can help donate to purchase the parts, and then part of or all of or x times the amount of the donation is taken off of their next order of a TEN-TEC product > a certain dollar amount.

No, don’t look for exchanging your $100 donation to cover 1/2 of a Rebel, that won’t happen, Talking a major product, e.g. an OMNI-VII, or a high powered amp….. To do this first class, we need a 200K capital infusion for a new factory building and some new equipment to replace what was liquidated if anyone cares to step up and accelerate our success. 400K would give us the facility, equipment and capitol to put everything back in production to a stocking basis and allow us to complete the Orion III. If 400 people will give us 1K each, we will commit to the Orion III of your dreams in 18-24 months and give you 2K off the target price of 5K as well as engrave your name and call on a plaque on the new building that says you helped build it and save TEN TEC.

Where do I fit in?

No, I’m not the owner, but I am going to do whatever I can in the evenings to ensure that TEN-TEC is a success. I want to see it be a success, and maintain what can be maintained of the people, and improve it’s image/products/etc back to where they were years ago. The owner is quite insistent that I remain intimately involved with TEN-TEC even if it is on a part time basis. It is my choice of how much or little I spend on TEN-TEC and the door is assuredly left open for me to come and go as I please. He wants me to be the VP of Engineering, but, well, time will tell how all of
this plays out.

I am also working on digital modes for HRD, so, my evenings are quite interesting.

In the future, who knows?

Where do you fit in?

Be patient, this is a total reboot of a company, ripping away the excess that bleeds it dry (e.g. high rent, using an MRP system that costs $$$$ monthly when something is already in place to take care of it, changing to a cost effective internet/phone system, so many “luxuries” will be removed and put in their place the necessities to get business going profitably), and building the business and products with the key employees to make it strong again. You build the employees, the employees build the company. But it will take time.

The products are there, the technology is also there for the future (some things that were in the works that no one in the public knows about) that the new owner has a plan to finish soon.

Actually, TEN-TEC does need to take the time it will take to make it a success. Otherwise if he runs headlong into this as was done in the past, he will fail. If people buy rigs and amps and tuners and other accessories elsewhere in the meantime, well, that is their decision. The market continually has new and continued customers. existing customers periodically look for something new, enough of a continual market that should sustain itself for years.

The new products coming out that are planned include continuances of good known technology, and of course some are a step ahead of what is in the market today, and you will see those in 1-2-3 years.

I will not divulge nor answer speculation on anything further than what I have stated above as to what products, when, etc. I can also tell you is that the owner has emphatically stated to me that this the last time Ten Tec will change hands for the next 15-20 years or so as he is my age and plans for us both to operate it until we are in our 70s or physically unable to continue, so Ten Tech could not be in the hands of anyone more SERIOUSLY long term goal oriented. He has wanted Ten Tec for a long time for the excellent DSP AGC technology built in to our transceivers so I
think it is safe to say that there will be future generations of the Omni, and Orion style units as finances permit. But again in order for this to happen it is critical that YOU support TEN TEC by purchasing existing TEN TEC products. Look for the Omni 7+ next year.

So, whereas he still wants to remain anonymous until his formal announcement in the first quarter, I myself am convinced that this will work, enough so to help him wherever I can, and so are the key core employees at TEN-TEC. If anything, our message at this time is please be patient with the negativity. There are other things happening behind the scenes which can not yet be publicly discussed before they are finished.

If this sounds like cheerleading, well, then so be it, I care about TEN-TEC, the people, the legacy, and will do what I can to make it a success, and, if this fails, well, we will give it a valiant effort.

Please understand that I have other commitments from now until Monday next week that I may not be able to respond/answer questions until then. But do realize, that I have disclosed about as much as I can for now. This statement came from a draft I created, and the new owner gave me inputs on, which items he felt like disclosing now, etc. So, there may be some he/I/our’s mixed up, but I hope the message from him is clear. TEN-TEC is something he is passionate about, and is committed to making it a success. Yes, there are trials and tribulations, but, he is convinced he
can do it, and I will do whatever I can to assist, and so will various core TEN-TEC individuals.

A Virtual Tour of WEAF in 1927
By John F. Schneider W9FGH

The iconic radio station WEAF in New York City began in 1922 as a grand experiment by the Western Electric Company, a subsidiary of AT&T. Western Electric was interested in exploiting its collection of radio patents, which it believed would allow it to corner the market in the exploding field of radio broadcasting. The station went on the air August 16 of that year from an antenna atop the eleven-story Western Electric Building at 463 West Street. WEAF was initially conceived by AT&T as a “toll broadcaster,” a radio-station-for-hire, with blocks of program time that would be leased to anyone that wanted to broadcast. Later, WEAF began broadcasting from a new transmitter site located in more rural surroundings on Maple Avenue in Bellmore, Long Island, 28 miles East of New York. John gives us a tour of this historic radio station.

Variacs 101: Answering those Questions
By Rich Post KB8TAD

One of the most useful tools for vintage radio repair and restoration is the Variac. All it does is vary the line voltage from zero to full and, depending on its connections, beyond full line voltage. It can be found in the chemistry lab, in older hotels and theaters for varying the lighting levels, as noise-free dimmers in recording studios, and as a way to gently warm up guitar amps from a cold start. It has been used to control the heating of soldering irons, to carefully adjust coffee roasters, and to increase the life of older incandescent Christmas lighting. And, of course, for radio restoration, it allows an older radio to be powered-up gently and at reduced voltage.

Retro Radio: Antique Radio Classics and the People Who Love Them
By Richard Fisher KI6SN

The dulcet tones of Dinah Washington, Frank Sinatra, Nat King Cole, The Andrews Sisters and Etta James no longer float through the air from the more than 2,500 radios consuming Barry Dagestino’s three-car garage and a nearby 1,000 square foot storage unit. The singers may be gone, but many of the radios that brought their voices to bygone generations are very much alive today—dusted off, rewired, restored and glowing from side tables and mantel pieces around the world. This first of the two-part TSM “Retro” series on Antique and Vintage Radio opens a window on broadcast band and shortwave receiver collectors, calling on the advice of experts to tell us how to get started in this fascinating niche of hobbyist communications.

Cutting the Cord: Part 1
By Mike Kohl

Much has been written in the mainstream press during the past several years about the subject of cord-cutting, which is the act of dropping cable-TV and other subscription services for less costly and sometimes totally free alternatives. This article is a primer on the options now available to most consumers, with future articles going into how-to details that will attempt to compare those options so that one can form an opinion about how to save money on home entertainment delivery.

The Spectrum Monitor is available in PDF format which can be read on any desktop, laptop, iPad®, Kindle® Fire, or other device capable of opening a PDF file. Annual subscription  is $24. Individual monthly issues are available for $3 each.

The IC7300 is being actively “pre-sold” with UK dealers asking people to part with £50 deposits to secure these transceivers when they become available. I don’t think any have shipped yet and I suspect it will be late spring before they appear in the UK.

http://www.icomamerica.com/en/media_events/news/NewsArticle.aspx?id=201521

The price will drop once the dealers have creamed good profits from those who must have the rig at any price – the early adopters. Really I would like the 10W version which would be a class QRP rig. This would be even better than the IC703.

It is quite likely that the early sets will have some software or hardware issues which will be corrected on later models sold.

Of all the products around, it looks the most attractive and I like the SDR architecture. Let’s hope the ball grid arrays are soldered well! From bitter experience I know this can be a nightmare tweeking the process.  I can wait.

ICOM America has more information on this transceiver.
