Summer Es - Sporadic E season


In the past week we've seen some increased solar activity; solar flux peaked at 74 and that led to some interesting band openings. I worked LY1000A in Lithuania late last night (20-May-2009) on 20 meters -- an opening to Europe near midnight local time certainly qualifies as "interesting".

The summer sporadic E season (often referred to as "Es") kicked in today with reported 10 meter openings from the west coast to the east coast. I worked KJ7OX in western Washington state just before midnight local time; solid copy on him and after I signed off he was still going strong.

Given that 10 meters was pumping I also listened up on the 11 meters CB band. As expected they were going strong too; I was hearing a lot of AM stations down below channel 23 and I also learned that apparently CB channel 38-LSB (aka 27.385 MHz) is the popular sideband DX calling channel. It was good to see the hams having as much fun as the CBers for a change.

There was an interesting study done on Es propagation by Art KA5DWI; compiled over four years of PropNet monitoring data it shows that "sporadic E" may not be so sporadic after all. One noteworthy finding; Es propagation during ARRL Field Day weekend is typically poorer than the preceding and following weeks.

S 649 : Radio Spectrum Inventory Act


I posted this because I think Senate Bill 649 : Radio Spectrum Inventory Act (intro'd by Sen. John Kerry-Heinz, D-MA) is the first shot in a battle I've been predicting for some time; the application of populist politics towards spectrum management and allocation. You need only spend an hour tuning around with a decent all-band receiver to discover that the vast majority of spectrum is nothing but static. The real targets of this "spectrum socialism" are the big guns; broadcasters, the military, and even divisions of the government itself (such as NTIA) which has been "warehousing" spectrum for years while hypocritically requiring auction-winning licensees for cellular/PCS spectrum to demonstrate high levels of loading; i.e. subscribers.

Radio amateurs, I believe, are especially at risk from unintended consequences if this bill becomes law. I've previously blogged that many amateur radio frequencies are largely unused. Some amateur bands; such as 1.25m (aka 222 MHz) and 23cm (aka 1.2 GHz) are used only in certain regions of the US. (1.25m is popular in the Los Angeles area because 2m is so laden with bootleggers and jammers it's effectively become CB radio.) One reason for this is that the radio manufacturers are not selling equipment for these bands; the last 1.2 GHz equipment was the Kenwood TS-2000X which was introduced 9 years ago. Alinco is reported to be releasing a 1.2 GHz handheld, but that's not enough to drive adoption of the band. If the RSIA is an attempt to document usage of spectrum as a precursor to re-allocation based on purpose and usage, then 23 cm is one of the most likely targets for re-allocation once the limited use of that band becomes public knowledge. Our only hope is that the proximity of 23cm to radio astronomy likely precludes the allocation of that band to commercial use; but it could still be lost.

Equipment availability is one issue but at a higher-level the problem amateurs face with RSIA is simply that there are fewer radio amateurs than there were in the past; younger people prefer communicating via the Internet and if they do express an interest in amateur radio they're all-to-often turned off by the arrogance of a few hygiene-optional curmodgeons who tend to hang around at club meetings and hamfests complaining loudly and constantly about how the demise of Morse code testing will lead to the death of amateur radio; ignoring the fact that it's their own urine-soaked elitism that's probably a key element in keeping younger people from the hobby. So when faced with a trend towards populist politics and thus policies, a Congressional Budget Office estimate that the federal deficit may exceed $1.5 Trillion dollars, and huge swaths of amateur spectrum laying increasingly fallow as the number of amateurs continues to decline; the likelihood that the government will pull spectrum from amateurs and attempt to auction it off as a revenue source is increasingly likely. It's critical that we change the face of amateur radio (even if it means slaying a few sacred cows) in order to attract licensees or the day will come that some lawmaker will decide that it's politically low risk to start pulling spectrum from amateurs in order to pay off the deficit.

Economy takes a dive; amateur radio vendors fail to notice


You'd have to be living in a cave to not know what's going on with the economy, or at least what Washington D.C. is trying to terrify us into thinking is going on. Setting aside this Recession vs Depression debate for the moment; it's clear that the economy is struggling at some level. We're seeing home values drop sharply, credit is hard to obtain, auto dealers in some parts of the country offering 2-for-1 deals, etc. One need only visit your local Best Buy, Fry's, etc to find smoking hot deals on consumer electronic equipment. A buyer's market you say? Apparently not for amateur radio.

Recently I decided to buckle down and learn CW aka Morse Code. I've been using various tools, including a great online trainer called LCWO (Learn CW Online). I've also been using W6TJP's Code Quick; good for getting the sound-alikes for each character but my advice would be to save your money on the optional software and focus on sites like LCWO.

Needing a paddle/key in order to practice sending CW I decided to stop by Ham Radio Outlet (aka "the candy store" and buy the Bencher BY-1 for what their printed catalog said was $99. I pulled up in front of the store and the parking lot (normally full of vehicles festooned with antennae) was so empty I had a momentary thought that maybe it was a holiday and I'd just forgotten. I walked into the candy store (normally full of amateurs festooned with antennae) and was greeted by one lonely salesman. Recession? Depression? Clearly business is slow.

Inquiring about the Bencher paddle I found it was in stock...and that it cost $109. Ex-squeeze me? Catalog says $99. Yes, but the price went up. Since when? Since the catalog was last printed, apparently. I see... So other retailers are slashing prices, people are spending less, your store is completely empty for the first time I can recall...and you're raising prices.

To his credit my friend gave me the catalog price. Normally I'd also get a discount for being a member of the Cactus Intertie group, but not this time. It started me thinking that I've not really seen prices fall on amateur radio equipment the same way that mass-market consumer electronics have fallen. For example; I've been saying that I'll buy an IC-7000 once the sale price drops below $1,000. And yet the price remains above $1,300 and from some retailers seems (like my Bencher paddle) that the price have actually increased.

Is amateur radio immune to economic downturns? Sure seems like the manufacturers and retailers think they are.
