[IRCA] Re. CFA antenna
Those of us of a Certain Age may well recall the CFA of the 60's and 70's - The 'Joystick VFA'. Go search it out on the net, it was very popular for a while. I suspect that eventually people figured out that the feed line was the active component of the antenna...

By the time it was dark for an hour or so and we were getting blase about the initial rush of DX from Europe, Africa, the Mideast, and sometimes India, then the Brazilians, Argentinians, and many other southerly goodies started rolling in. Depending on conditions, these could persist well into the wee hours of the morning. Additionally, as westerly-progressing sunrise knocked out one group of TA's after another, lower powered British and other stations on the western flanks of Europe and Africa, signals previously buried by Mideast megawatters, would come into their own. In essence, maybe only about 6 hours out of 24 could be considered non-DX time. There were some decent fish places in the area the first few times I went up to Cappahayden (e.g. 1991, 1993). The poor economy caused by the decline of the fishing industry around there resulted in one restaurant after the other "going dark" as the years passed. Typically the communal DX shack room had snack material (chips with dip or salsa, pretzels, nuts, crackers, cookies) of dubious nutritional merit. At least once in a while, oranges or other fresh fruit showed up. No matter how you looked at it, however, there was nothing distinguished from a culinary standpoint. Drinks?

DX efficiency typically declined a few notches at that point. Some of us had very early flights out the next day so we couldn't get too blasted. On the subject of diminished DX efficiency, of course nowadays with SDR's, most of the serious DX analysis goes on weeks or even months after the actual reception times. So as long as you're not so inebriated that you delete (or fail to save) the capture files, you can still make a go at some good DX as long as the alertness is there when you finally do get to dig through all those captures. Even with the benefit of an eventually-bigger logbook, the after-the-fact nature of DXing with SDR's does take away some ! of the old-school "fun factor" of immediate gratification and in-person real-time success-sharing with your DXpedition comrades ... stuff that the late John Bryant celebrated so well in his kid-in-a-candy-shop-enthusiasm writings from the ol' knob-twisting and cassette-recording "dark ages". After-the-fact DX also tends to take useful tools such as shortwave parallel checking, webstreams, and remote web receivers out of the game.

Re: [IRCA] IBOC - Patrick's question
"Do you get any distant FM IBOC? I cannot detect any FM IBOC hash here on the Oregon coast from either Portland or Seattle stations, so I wonder if I woul get any FM IBOC out here." Hi, Patrick. In this neck of the woods (northern New England) the major IBOC players are the NPR stations. Vermont is doing a good job of getting IBOC online on FM although the gentle art of actually streaming the title of what you're listening to seems to be a little beyond their ability to figure out. Which would be nice if they did, seeing as IBOC mainly carries their classical service. I suspect (because of the behavior of the work truck's "scan" function) that there are a couple of stations in NH/VT that are carrying IBOC other than VPR (Vermont Public Radio) but I haven't yet tried to see if they're decodable at the home location. I do note that FM IBOC is far less obtrusive in terms of adjacent channel interference than it is on AM. Hm, mebbe when I get home in the morning I'll do a quick FM bandscan and see if anything shows up - I know AM will give me bupkis...

[IRCA] IBOC, D.C. 1500 propagation
IBOC - I acquired a refurbished Accurian HD radio from Radio Shack - I was curious about IBOC even though I'm none to fond of the racket it generates. It works beautifully on FM IBOC with the local NPR outlet some ten air miles or so from my home. On AM it has been unable to decode any station using the RS passive AM loop I have hooked it up to. Of course, NH isn't exactly a hotbed of IBOC but I would have liked to have had a shot at the AM in Keene, under 26 miles from where I live. Once I get the LF inverted Vee back up I'll give it a shot on AM with that, but I'm not going to hold my breath. Thus far AM IBOC has proven to be nonexistent as a listening mode here. D.C. 1500 - can't speak as to the daytime, but I spend a lot of time on third shift in a turck listening to AM radio as I drive in endless circles. 1500 out of D.C. comes in very nicely all night long - I particularly enjoy listening to the couple of hours of The Twilight Zone they put out on Sundays from 000-0200. Side note: Listen on 1700 (or is it 1701?) kHz CW for the NHVT Medfer beacon in Charlestown, NH. Let's see who can hear it and where.

[IRCA] LF Engineering H-800 opinions sought
I can get one decent wire antenna up where I now live (a 160-80-40 trapped dipole in inverted Vee configuration) and a number of pole-mounted antennas (sticks, discones, that kind of thing.)

[IRCA] iPhones and IBOC
Craig wrote: "This from today's Inside Radio. No receiver at all, much less one for IBOC. It will receive audio streams, however. It's also interesting to see they expect sales of 10 million units vs. the 300,000 that iBiquity claims for HD Radio receivers - which includes automobile factory-installed units. And it's cheaper than most of them, and does many functions instead of just one for the HD radios. Personally, I hope this is a big fat nail in the HD coffin." You know, Craig, I have a more than sneaking suspcion that within the next couple of decades we're going to see OTA radio (including satellite delivery) go the way of the Dodo in any major population area (or well-travelled highway.) The 'net streamcaster model is going to continue to evolve and will become the preferred method of delivery and programming for Joe Listener. Outside of the areas where a good wireless soup can be maintained you'll still have viable markets for listeners but even they (the stations serving to fill those holes) will have to start thinking about serving the audience rather than shareholder value once more. The down side of all this is that radio stations will drastically decrease in numbers on AM and FM. The up side is that (barring PAC-motivated federal interference) the stations left for us to listen to (and DX) will be much more in touch with their audiences' desires and far less likely to belong to a monolithic entity. So, now's the time to buy those AM and FMs with good coverage *outside* of major metropolitan areas!

Re: [IRCA] HD Failure
Option 1 - Take the hard drive out of the casing, connect it directly to your computer as if it were a regular internal HD. This eliminates everything but the HD as a possible source of the problem. Option 2 - If the problem persists after Option 1 and you consider the data to be that important, you have the option of obtaining an identical model HD, establishing that the new HD works when directly connected to your computer and then swapping the HD electronics boards over. This is not for the faint of heart. This eliminates the HD electronics as a possible source of the problem. Option 3 - If the problem persists after Options 1 and 2 are executed, chances are that the problem is mechanical/electromechanical in nature and would require the services of a data recovery house. That is an expensive proposition. I can vouch for Options 1 & 2 personally. Option 3 I wouldn’t pay for. Lee No virus found in this outgoing message. Checked by AVG Free Edition.

[IRCA] How things sound to me since 9/14
Well, did finally sit down and take a quick look across the band to see how things were sounding since IBOC went 24/7. Basically, wherever I have a station that's of good stregth running IBOC, I lose the upper and lower adjacents. Didn't try phasing the hash out, I still have to get the second antenna for that purpose erected. Fortunately there still aren't a huge number of stations running IBOC as yet even up here in new England. WOR had an excellent signal up here as ever (S9+20) but the adjacents were wiped out, of course. WBZ was wiping out the upper adjacent but KDKA was nicely audible on the lower due to its strong signal. Thought: Has anyone with an HD-capable radio taken a look at how well two strong HD signals live side-by-side? Does that seemingly extra hash produced at the +/- 10kHz mark degrade the audio recoverability for both or not affect either?

[IRCA] IBOC
It's not about the audio, it's about monetizing what couldn't easily be charged for using analog transmission systems. It doesn't matter whether or not the public want it provided that the FCC can be induced to do an end run around public wants and needs by unilaterally declaring that analog AM and FM will be phased out by a certain date. If that's done, IBOC is here to stay. And thus will the terrestrial equivalents of Sirius and XM come into existence. Shutting down free-to-air AM and FM within a certain time frame is a tricky gamble for IBOC proponents - the timing is particularly critical because they need the current corporate-friendly, listener-unfriendly FCC in place - but if they manage it then there's a pot of money to be made for corporate interests.

[IRCA] DRM - how well it works
I've been listening to DRM for three or four years now. Never heard IBOC - I refuse to pay $199 for something (the receiver) that should cost $25 at most. Observations on DRM and how it compares to people's comments on IBOC. DRM sounds fine - better than AM SW, near FM quality - when it can be received. Both encoding/modulation schemes have the same three problems - - A drastically reduced coverage area. - Extreme vulnerability to interference or propagation changes. - Interference to adjacent channels. DRM is more user friendly inasmuch as it's an open system and it's easy to see what audio bw is being transmitted, what CoDec is in use, etc., etc. AFAIK there are, at this time, no easy to use tools for divining what's going on in an IBOC stream. RCI regularly make DRM transmissions on behalf of various customers from Sackville, Canada. I *may* be too close to Sackville for proper SW propagation but I find that reception is spotty and frequency/time dependent. There is no such thing as 24 hour reception of DRM. It's also heavily dependent on bandwidth/FEC tradeoffs - the lower the audio bandwidth the more forward error correction data that can be sent to render the signal more robust. One of the more sublime examples of audio bandwidth versus error correction is being able to receive a transmission from the middle east that's a S7-8 with a 11kHz audio bandwidth (when decoded) whilst being unable to receive an S9+5 signal from Canada that has a 22kHz audio bandwidth encoded in it. There are tranmsissions from outside the USA but not a large number of them are decodable on a regular or continuous (as in: no audio dropouts) basis. BTW, for continuous audio decode without dropout you usually need a S9+15 signal. DRM, like IBOC, is in no way whatsoever a DX mode. So far, apart from a few tests, I have yet to see any DRM station (decodable in NA) making use of the data transmission facility that exists within it. What it all comes down to, really, for both schemes is improved fidelity, vastly reduced coverage, interference to adjoining channels (on AM and SW.)

[IRCA] Dialup speeds
If you get okayish but not great dialup speeds, you can also try MPPP connections to the web. Basically Windows will allow you to connect a second modem and phone line, you then dial into your ISP on *both* lines and Windows will tie the two lines together and make them into one pipe with the combined bandwidth. Your ISP has to support it as well, of course. They usually do. I used it for a while at my location (Goatbum, NH) out in the boonies, but eventually I switched to WildBlue satellite service - the phone lines, even two of them, were just too bad to be usable for data. The humorous thing is that I'm all of about 4 miles from the local exchange and they still haven't gotten off their cellulite-laden *sses to provide xDSL out here Lee ___ IRCA mailing list IRCA@hard-core-dx.com http://montreal.kotalampi.com/mailman/listinfo/irca Opinions expressed in messages on this mailing list are those of the original contributors and do not necessarily reflect the opinion of the IRCA, its editors, publishing staff, or officers For more information: http://www.ircaonline.org To Post a message: irca@hard-core-dx.com
