The Geloso G.215-AN I have recently been re-exploring the hobby of photography, which is a lateral move from studying astronomy (my main interest being astrophotography). At one time in my life I was a semi-professional photographer, having studied photojournalism in college and dabbling in nature and street photography (as it is now named). And no, I was never a paparazzo! Following a link from an article on today's SWLing Blog I landed on an Italian radio/audio company's archive, the company being Geloso. The above image is an audio amplifier and it caused me to think about radios (and related equipment)
We all need a little humor now and then! Recently the "Frank and Ernest" and "Ziggy" comic strips have been really causing me to have a chuckle in the mornings. I get a compilation of comics each morning for many years now, and often they help to start the day on a bright note. How clever is that?! Sent from a friend recently - cute, and not a small amount of truth, especially in a culture obsessed with always wanting more. I love this one!! Now, whoever came up with this one is really clever! Enjoy! 73, Robert
One would not think radio could be a window into the soul, but for me, at least, it is. A recent discussion with a friend brought to mind various hobbies I have enjoyed the most over my life, and Radio, Woodturning, and Photography grabbed the top three spots. I won't begin to try to rank them! What I did realize is that all three relate to my desire to be in touch with this incredible Creation. Photography (nature, animals, astrophotography) all cause me to be in awe of the world (and universe!) around us. Sometimes in nature it is the

I love old radios, as any reader of this blog will probably know. My collection has grown both in quantity and in variety. Like with any hobby, there is only so much room for storage and/or display before you have to downsize a bit to grow in new areas. I am selling one of my childhood favorites (never owned one as a kid, but my mom had an earlier version of this radio, the 3000) to make room for a new boat anchor. I am mentioning this here (and I promise not to do this often) because I realize some

Beating the Solar Minimum Doldrums
04/04/2018
Experiments with SDR Luigi Freitas Beating the Solar Minimum Doldrums Solar Minimums. Yes, they are a drag. We've been talking about the solar minimum for some time in the amateur radio community, but of course we are not the only ones affected by the lack of vigorous ionization. Shortwave radio is affected, utility monitoring is affected, as well as almost any signals dependent on the atmosphere for propagation. And yet . . . . The truth is there are always radio signals of one form or another traversing the sky, running along the ground, or shooting straight at us from
I have placed on the Reviews and How-Tos page a review of the FoxDelta Antenna Analyzer kit originally published in The Spectrum Monitor.

A New Year, A New Radio
01/03/2018
I confess to being quite excited! Not by the New Year so much (I've seen a lot of those come and go!), but by a new radio I received last night. The radio is a uBITX kit by HF Signals (http://www.hfsignals.com/index.php/ubitx/), covering the HF band for reception (yeah, shortwave!) and transmitting capabilities on the amateur bands up to 10 Watts. Here's a description by the manufacturer: The µBITX is a general coverage HF SSB/CW transceiver kit with features you NEED for operating ease, convenience and versatility. It works from 3 MHz to 30 MHz, with up to 10 watts on
Many of our readers are familiar with The Shortwave Listening Post by Thomas Witherspoon, and consequently are familiar with his non-profit group, Ears To Our World (ETOW). EOTW works with partners around the globe to provide radios to schools in areas where electricity is either non-existent or very spotty. The radios are ones we are familiar with, Tecsun Green-88, having the option of being powered by several means: FM/AM/SW 4 Band Radio. Proprietary tuning knob speed control. 2.5 inch Speaker with excellent sound quality. Hand crank recharge. High Efficient Power generator for cranking charging. Built-in
Believe it or not, it was not all that long ago when computers were new and amateurs started to integrate computer technology into their shacks. Fast forward 30-40 years and most amateurs have a computer somewhere in their radio room. Or at least I am guessing this is the case. I am not so sure that I would bet the family farm on this statement. Perhaps better to say I presume such is the case. I bring this up because I see a great deal of hesitation for folks to try new things, particularly when it comes to computers, digital
Long ago I "cut the cable" and started watching over-the-air (OTA) TV. Your remember, it's the TV most of us grew up with if you were born pre-1980. I actually use my police scanning antenna on a splitter to receive my TV signals, and it works pretty good (I get about 30-35 channels). The only problem with OTA programming are those dagnabbit commercials! I can't stand 'em! Fortunately there is another type of OTA TV, called Free-to-Air satellite, or FTA. I have written about this before The Thrill of Discovery so I won't cover all of that ground again. Commercial

Winter Nights, Radio Nights
10/02/2017
October is here and for those of us in the Northern Hemisphere, days are getting shorter, temperatures are finally cooling down, and fall is almost here. In other words, Radio Nights are here! I love fall and winter for the radio opportunities they bring. Quieter atmospheric conditions mean more signals to hear, more beacons to catch, and more radio activities. Pirates will be on the air toward the end of this month, as Halloween brings out many pirate radio stations. AM broadcast chasing really comes into its own during winter months. On quiet nights you can expect to hear stations

I worked the station on 15m and 40m FT8 mode, as indicated from their award lookup page shown below. One of the neatest things about amateur radio and shortwave radio is learning about new lands and some of their history, influence, etc. You may have noticed the award and the log-check page are in Russian.

I will be the first to admit I am a radioholic - I can't seem to get enough radios or radio accessories. This has led to overcrowding in the shack, moments of "oh I forgot I had one of these," and many times the throwing up of hands in bewilderment as I try to find an organizational and storage structure which makes sense. I would take a picture of my shack but it would be too discouraging, as well as having to make it a panoramic. No one shot would cover it all. This is not to say I

What is the Price of Negativity?
08/31/2017
With all of the buzz created by our recent Solar Eclipse here in the states, many hams wondered what the effects of such an eclipse would have on propagation. I admit I was mildly curious myself, but did not expect big swings in any direction. Locally the effect was pretty minimal, even with 91% totality. I expected the sky to get much darker than it did here, but in reality, it didn't even come close to a mildly cloudy day. But there has been enough written already about the solar eclipse, and much more will be written. My interest here
(Okay, a bit of hyperbole!) Visit the Restored "Interesting Links and Books" Page for new resources where I have added some of my favorite YouTube video links in Electronics, Radio, and Propagation. I am working to resolve email issues (that's why there have been no new posts for a while), but I confess, it is a mystery why they suddenly stopped working. Apparently I am the only one on the planet to whom this has happened! (At least I cannot find any solutions through my usual sources, that is, Google!)
I seem to be a man of contradictions. As I look at my "shack" (amateur radio speak for where I keep my radios!) I must be conflicted. I have radios from the 40s, 50s, 60s, 70s, 80s, 90s, 00s, and the 10s. I like radios of every era as each radio is a marvel of technology from the simplest to the most complex. Even radio designs we take for granted today are scientific wonders, and radio is itself, of course, magic! On the same table I use for day-to-day radio fun, I have two modern marvels of technology, and four
Memorable Radio An interesting post from the excellent SWLing.com Blog got me thinking about memorable radio sounds and segments. The post referenced a piece done by "Twenty Thousand Hertz" on the historicity and significance of the NBC chimes. There was a lot there I did not know. One of the things I found most intriguing is the idea of how these three notes (originally 7!) have been a part of our culture for 90 years! They have signified triumphs and tragedies, milestones and things we would rather forget. And they were even used in WWII in a special way (No
Today a good friend of mine, Justin KE8COY, posted a link referencing a broadcast piece on Natural Radio - a reference to the radio signals produced naturally by the earth. The piece notes how it was Thomas Watson, co-inventor of the telephone, who first heard the earth's radio signals coming over a telephone test line strung up over the roofs of houses in Boston. The piece is fascinating, and opens up yet another aspect of radio I (and Justin) find fascinating. And yes I know I am using "fascinating" repeatedly to describe this aspect of the hobby, but it truly
I ran across a post in an eham forum on the topic of Elmers where the person was contrasting Experts and Elmers. It was a well-written piece, and the follow-up comments were sometimes equally interesting. More often than not when a person asks a question in a forum or on a chat board or a mail room, experts jump in and (attempt) to show off their knowledge. Obviously, there are real experts in any field, and their input is always useful because it is more likely to be correct. But the so-called experts to which I am referring are the

I had an interesting experience this evening listening to the Voice of America's digital broadcast (I have mentioned this in previous posts) as Hurricane Matthew pounds the eastern seaboard of the Carolinas. The atmospheric noise tonight was almost like the waves of the ocean crashing in along the beach, receding and coming again with a new wave. When I first tuned into the broadcast on 5.745 MHz I could barely hear the opening theme music or the initial voice introduction. I wondered if I would pick up anything at all.

This summer has been a tough one for me in many ways, not the least of which is the minimal amount of time I have been able to spend playing radio. I have several commitments involving radio each week/month, but I do not consider that "playing" radio. To me, playing radio is where we get to sit down in front of a radio of any kind and do something with it just for the pure joy of it. The good thing about this hobby is it is always there whenever you are ready. It is like a good friend who

A blurb in the QRZ.com News and in the ARRL weekly newsletter caught my attention concerning an interesting reception report involving the ISS (International Space Station).

I have logged many APRS signals (including several DX stations!), as well as a dozen or more states.

I find old radio souls now and again who seem, at least to me, to be in touch with the spiritual side of radio. I am not talking about religious programming or some weird cult, but rather they are folks whose souls have been touched by the magic of radio.

It is as though our minds are connecting with the radio signals like old friends, able to hear and be heard. Yeah, I know, I am weird.

04/04/2016
A typical radio day for me usually involves several different aspects of the radio hobby. Granted, I may include things others would not strictly call radio, but for me anything associated with the radio hobby is fair game! Sometimes this can be something as mundane as logging contacts, or checking for QSLs (confirmed contacts with other radio operators or stations), or it can be as exciting as putting some test equipment to work checking circuits or measuring frequency response. For me anything connected with radio in almost any form is interesting. A typical day (or portion thereof) might involve listening
One of the best things about the Internet is the ability to tap into a vast supply of knowledge available from a multitude of sources.

For some reason I have never been much into FM DXing, and I am not sure why. The best answer I can come up with is the FM signal, because it is so much higher in the RF band, never has a chance to travel very far even with the best of conditions. Of course I am not referring to special propagation conditions like ducting or the like, but just day-to-day listening opportunities. I am an "AM man" through and through. To be fair, I have never given FM DXing much of a chance because usually the best DX you

WWII Promotional Piece for Hallicrafters

Here's an interesting 15 min. video demonstrating the Army Signal Corps using an Hallicrafters SCR-299. While certainly a promotional piece for Hallicrafters, this has great footage and captures a bit of the excitement of radio expanding into new frontiers. There is a discussion of how the radio was modified for military conditions as well as some innovations which were implemented to make such a system mobile. I think what intrigues me most about these types of pieces is the sense of a common purpose -- the nation was at war and everyone was pitching in. Yes, Hallicrafters was a business
