[IRCA] TP/Micronesian Radio
I've got Five 45 minute airchecks from KUTE 88.1 FM in Colonia, Yap, Federated States of Micr(aka V6AI, the 10,000 Watt AM signal at 1494 is off air awaiting a new transmitter) They were recorded the second week in April, locally by the State Chief of Media Protocol along with his staff and sent to me on cassette. They are about 21 megs each, give or take. I will post them online this afternoon and share the links with anyone interested. I'm awaiting Airchecks from WAAB-TV, The State owned TV station Colonia, Yap, Federated States of Micronesia along with Radio Cook Islands 630, V7AB Majuro and Atlantic FM in Tristan Da Cunha. I will share those when they come in.

[IRCA] New Australian Radio Guide
For anyone interested: --- Australian AM Radio 1611-1701 Italian, Country, Arabic, Greek and Gold Almost 70 low power stations are now broadcasting in Australia's expanded AM radio dial almost two decades after the new channels became available says the Radio Heritage Foundation which has just updated a contemporary guide to them at www.radioheritage.net. Originally populated by ethnic broadcasters and niche formats, the situation remains little unchanged in 2010 as attempts to bring the low cost extra frequencies into mainstream media have largely failed to materialize. Existing commercial broadcasters saw these licences as a dangerously cheap back door into digital broadcasting and lobbied strongly to exclude 1611-1701 AM stations from digital entitlements. Coupled with poor availability of AM radios able to tune to the new frequencies, attempts by commercial aspirants like Radio 2 to establish economics of scale and a nationwide network collapsed. In 2010, the major players on air are Rete Italia [part of the Italian Media publishing and media group], The Goanna [a fledgling country music network co-owned with 2ME an Arabic language station], Smart Group's Hot Country from Queensland, whilst small footholds in the band have been claimed by 3ABN and Queensland based Christian network Vision FM. A small cluster of independent stations air a variation on the 'Gold' music format of 1960's hits popular with babyboomers, two Greek language stations compete for listeners in Sydney, and a handful of other stations serve ethnic markets for Chinese, Hindi, Arabic, Islamic and Lebanese Christian audiences. A large number of licences held in the 1611-1701 AM band have remained silent for many years and are unlikely to ever come on air. The Radio Heritage Foundation has released a detailed list of Australian stations currently operating in the 1611-1701 AM band together with analysis of this fascinating and little known broadcasting landscape. It's currently available as a downloadable Word document at www.radioheritage.net and will be updated regularly. Radio Heritage Foundation is a registered non-profit organization connecting popular culture, nostalgia and radio heritage across the Pacific. The global website is www.radioheritage.net and all content is available free. Annual supporter packages starting at US$10 and online advertising rates are now available.

Re: [IRCA] Intriguing DXing locations
To add to what Mike had to say on the subject. In mid February 1988 we had a small family excursion to Rockaway Beach on the southside of Pacifica CA. I'd brought my portable radio with me and around 3pm I started to get sunset skip on the beach. I upped my log on Oregon stations by a bunch, they were all over the place. We packed up and left around 4:30 as it was getting bloody cold by then. As we pulled out of the beach parking lot and onto Cal Hwy 1 the skip signals diminished and the locals took over. On the other hand, while dxing from the Sacramento area I had (at times) fantastic reception from Hawaii, Alaska, Tonga, Australia/N.Z. especially Japan. Even better reception from Asians was logged from S.F. in the late 70s and I was 25 blocks from the beach and on the leeside of a hill (that once had been a dune). Oddly I am now located about 15 blocks from the beach and even if all my noises would disappear I'd not have anywhere near the reception I had from further out in 76-78. Don K.

Now that I don't have to go there for work anymore I don't even go to downtown San Francisco if I can help it. Don Mike Hawkins wrote: You didn't go downtown after dark, did you?

I went up to Don Kaskey's house a few times and we listened on car radio and on my Grundig at the beach in San Francisco. I drove the Great Highway south after leaving and had strong signals on several TP frequencies. When I turned inland, the signals dropped off dramatically. Many were gone by the time I was 3 miles inland, though the stronger ones lasted until I was 10 miles in, and the strongest continued on. One night in 1980/1981, I went out to an artichoke patch (I think...it was dark and rainy) north of Santa Cruz with Doug Nyholm (remember him?) and we strung out 1200-1300 foot of longwire on stakes attached to his Yaesu. We had reasonable audio on 30-35 TPs from Australia/New Zealand/Fiji. I had never heard most of them before or after that night. There have been some good exceptions to the rule though...I used to pull in a AM station from Malaysia with some regularity when I lived in Manteca CA, which is politely referred to as the armpit of California. I also had armchair quality on a Central Chinese station on 1525 kHz way back when.

I was also wondering how close they were to the ocean; my understanding is that going even a few hundred yards or so inland puts a significant damper on TA/TP signals - can any TA/TP veterans confirm/correct this? Hi Kevin, I suspect that the amount of loss is somewhat dependent on the ground conductivity of the inshore land, the frequency of the signal, and the arrival angle of the signals, but only really have data for the second of those suppositions. The others are based on the supposition that a low arrival angle signal from over the ocean will lose strength more slowly over highly conductive land (salt marsh) compared with poorly conductive land (rock) the further it travels. A high arrival angle signal, on the other hand, presumably will not be as affected by ground conductivity so one might assume it will be nearly as strong inland as at the shore. As for the second supposition, a few years ago, John Bryant and I did some simultaneous signal strength recordings at the shore and points up to around two kilometers inland at Grayland, and found that the loss was highest for higher frequency signals, and varied from 1 to 12 dB depending on how far inland one was (but signals were almost always best right at the beach). It didn't seem to be a linear decay, rather there seemed to be reinforcements and cancellations of signals at different points, so one might luck out and hit a pretty good spot further inland, so one shouldn't out of hand reject a site a little ways inland. Randy Seaver wrote a good article years ago about this, entitled Sea Gain which is IRCA reprint T062, and some of our results did seem to have some theoretical underpinnings (Randy had found some academic work on the subject). Unfortunately, both John and I were pretty busy at the time, and never really finalized any conclusions on the subje! ctmore study is needed (I'm sure Mike of the Grayland motel would be OK with several weeks of rental from DX researchers.). best wishes, Nick * Nick Hall-Patch Victoria, BC Canada ___ 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 ___ 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
