Yes 98.5 is clear in Toronto.There is 98.5 from Kitchener.Buffalo stations with interference problems are 106.5,92.9,104.1,103.3,94.5,93.7,96.1,96.9.The 106.5 is totally blocked with Toronto station on same freq.
92.9 - closest adjacent is 93.1 Barrie. That shouldn't be a problem

93.7 - closest adjacent is 93.5 low power from Toronto, can be a definite problem

94.5 - closest adjacent is 94.7 Hamilton / Burlington. That could be problem

96.1 - closest adjacent is 96.3 Toronto (not CN Tower), had recently upped power (within the last year, now a powerhouse) that will definitly be a problem

96.9 - nothing adjacent on either 96.7 (Kitchener) or 97.1 (Belleville) that I know of. 97.3 is Toronto, but that's 400KHz alternate and shouldn't be a problem.

98.5 - Clear as you report, but note: 98.1 Toronto (CN Tower) is 400KHz alternate spacing... Me suspects other factors at play in the 96.9 problem.

103.3 - closest adjacents (2) are 102.9 Hamilton, 103.5 Toronto (or more precisely slightly north of Toronto) Both could be problems

104.1 - closest adjacent - 103.9 Toronto low power (deviation is set a touch high I notice which could aggravate things) 104.5 is Toronto CN Tower, but again, that's 400KHz adjacent

106.5 - Co-Channel - 106.5 Toronto. Receiver's capture ratio will take care of any chance of out of town signals. In case of an inversion (enhanced reception), in stereo (which technically has a much much lower capture ratio anyway) you'll hear additional distortion and background "racket" that follows the modulation patterns of the other (in this case) Buffalo station. That's why no-one is honest enough to even think of stating their stereo capture ratios... :) The figures would look terrible. Not a fault, just inherent in the FM stereo mode of broadcast and reception technology.

You kinda got a long winded response, but to others who aren't in such a congested radio enviornment, which the corridor from Pickering through Toronto, to Hamilton is, and Toronto north to an extent, can place horrendous demands on even the best in tuner design. What was interesting is, back in '92 I took a trip to England, and took along a pocket AIWA thin FM radio. Here in the Hamilton - Toronto area, it overloaded a lot, but had good adjacent channel rejection. In England, it operated flawlessly, everywhere. They don't use anywhere as much power, and had good coverage. Here, the days of 100KW assignments are pretty much gone, except in northern or unpopulated areas that need a flame-thrower to cover a large geographic area. Lower powers allow more stations, with less coverage.

Further to reception problems with Buffalo fm in GTA.96.9 has Humber college radio,North Etobicoke 10 to 15km range.In Mississauga 98.5 is replaced by the Kitchener station from Miss. rd and 401 west.92.9 is unlistenable in Mississauga with the new Halimond area station.So that leaves 102.5 as the only possible HD radio station from Buffalo since the digital signal is on the sides of the analog signal for me in Mississauga.Too many stations in the area ,poor management by Industry Canada and the CRTC.Everytime a new station comes on it blocks the reception of 2 adjacent channels.

I guess basically the answer therefore lies it depends on where exactly you are in the GTA, as results are for sure going to vary...

I wasn't aware of the Humber College station at 96.9.

If it weren't for the 20KW signal less than a quarter mile away from CIWV, 94.7MHz, I'd probably be fine with a lot more distant stations.

On pocket radios, most interference is comprised of 94.7 Hamilton, and some mixing of various Toronto stations with themselves and 94.7. This shows just how strong stuff from Toronto comes in here. In fact, 94.7 even causes background noise on 95.3 Hamilton, and that's 100KW from the other side of the building, but only slightly further away.

Add a little inversion, and Colberg comes in well, Rochester (89.9) and 106.3 from Eastern Ontario somewhere, or Quebec, not sure exactly.

Way too much receiver overload for serious sporadic-E reception, unfortunately.

Any updates, and are any Torotno stations braodcast in digital?:o

They're almost all broadcasting in DAB digital. Nobody's broadcasting in HD. Nobody's applied. No radios are available in Canada.

per an announcement by Industry Canada on Oct 12, 2007 (http://canadagazette.gc.ca/partI/2007/20071020/html/notice-e.html#i3):

The Department continues its commitment to afford Canadians the highest quality and variety of broadcasting services. At this time, the Department is of the view that experimentation with hybrid digital radio (IBOC (http://en.wikipedia.org/wiki/In-band_on-channel)) broadcasting would be beneficial to Canadian broadcasters and to the Canadian public.

In the United States, the Federal Communications Commission (FCC) has introduced hybrid in-band on-channel (IBOC) digital radio in both the FM and AM bands. Over 1 300 FM stations have been authorized to broadcast digital radio. These are all provisional operations, as the FCC has not yet enacted a permanent set of rules and procedures. On the consumer side, digital receivers are available at major U.S. retailers.

The Department is now prepared to consider applications for experimental hybrid digital radio authorizations for existing FM radio broadcasting undertakings in Canada. At this time, it has been decided not to extend experimental authorizations to AM undertakings, as this would be premature.

Future actions

Should these experiments prove successful, Industry Canada will work with the public and private broadcasting industry to develop the required technical regulations in order to accommodate hybrid digital radio on a more permanent basis.

FM radio signals travel very similarly to VHF-lo band TV signals, meaning long distances and fairly good penetration through forests, urban centres, etc.

HD radio receivers have multipath interference rejection qualities similar to those of ATSC OTA digital TV receivers, so no matter where you are in Southern Ontario or the BC Lower Mainland, if you can get Buffalo's or SeaTac's regular FM radio stations you will get the HD ones.

If you already have a CM4228 OTA TV antenna pointed at Buffalo or SeaTac you can split off a coax lead to an HD Radio receiver and likely get solid, reliable FM reception in my own personal experience, due to a quirk of its design. The CM4221 or other UHF antennas won't help you much for FM, unfortunately.

If you already have a VHF yagi or VHF/UHF combo yagi up there then you are already set for splitting off FM.

If you want to put up a specific FM Radio antenna you should check out Delhi's 2 models. One is the omnidirectional dual-perpendicular-dipole C667M and the other is the directional QFM-9 Yagi. Channel Master has stopped making FM-only antennas, but Winegard continues to make the 6000 yagi and the 6010 omni.

Get a sneak preview of high-definition radio in Detroit

Daily Oakland Press, August 15, 2005
By: Art Vuolo

Last week, my colleague Mike Austerman reported on the debut of HD (high-definition) radio in Detroit. Besides offering a high quality digital version of a station’s signal, HD allows for “secondary” channels that can offer more specialized programming than their primary stations — all in the battle with satellite radio for listeners. Two years ago, the mammoth Consumer Electronics Show in Las Vegas offered a taste of HD, but I just experienced it locally and want to share what I saw and heard because it is impressive.http://www.michiguide.com/archives2005/2005/08/get_a_sneak_preview_of_highdef.html

Received a Sangean HDT HD radio component tuner.Locking perfect on 4 Buffalo NY stations in HD.WNED 94.5 HD1 & HD2,WKSE 98.5 1 & 2,WDCX 99.5 1 & 2,WTSS 102.5 1 & 2.Not locking onto WBLK 93.7 and 103.3 WEDG in HD but indicates it.Regular FM comes in great.This is a very selective and sensitive tuner with a remote.Also WGRF 96.9 is transmitting HD but not locking.

rob50312, could you run a monthly scan through all Canadian FM's that you receive. It would be interesting if any testing preceeds any anouncements on the CRTC site. :-)

By way of comment, no change in the Toronto DAB scene, all 5 ensembles are up and running, but 680NEWS, CHFI, AM640 (Labelled Mojo640), CJMR and CJYE are silent without any audio, and it's been that way for several months now.

I've been eyeing this particular tuner myself for several months now, but I guess the big question is how does it sound in HD? Does it really sound like all the samples that are floating around on the web from the HD radio manufacturers or does it (hopefully) sound better than these? FWIW, of the actual live Canadian DAB broadcasts I've heard, I would be very surprised to learn that IBOC/HD could come anywhere close to the fidelity potential of the Eureka L-147 system.

BTW, can you pick up any AM HD stations?

FLACer no I have not tuned in any AM hd stations.I listen mostly at night .Most AM HD stations turn the HD part off at night because of skip problems.The sound is definitely better than those internet samples stations.HD sound is only a little better than that of FM. The Sangean tuner matches my modified Onkyo for selectivity and sensitivity but does not offer the same level of control.Sangean is a great tuner.

Just wondering if anyone has used an HD Radio in the Toronto area. I realize we don’t have any local stations currently broadcasting in it, but I was thinking some of the stronger Buffalo stations might reach us here.
I’m curious if...

A: will it reach us here ( I know the regular signals will, 94.5, 102.5 etc).

B: Is there anything decent on them, 102.5 HD 2 channel is suppose to be 100% blues music.

Thanks

Ah good, I see I missed this thread entirely & most of my questions are already answered.
Thanks for moving it.

Thank you for the link Stampeder. I've asked before if anybody had any experience with HD Radio? Any i see okmrbh is curious too.
I'm going to break down and buy one for the car just to see if we can get Buffalo stations on this side of the lake. I travel in the US sometimes so it will be nice for for Summer vacation anyway. Planning a trip to Bristol for the Sharpie 500 in August.

Hi everyone, i installed a turnstile FM antenna on my roof however i found it to be a short range omni-directional antenna. I live in Hamilton Ontario and i see that Buffalo (roughly 40-50 miles from me) is loaded with HD radio sataions. However after setting my presets on my receiver i only get a few of them and i'm planning to upgrade to a reciever with HD radio. Anyone with suggestions on an antenna that will pull in these stations (bonus if i can still grab Toronto only 30 miles away) Thanks for your time, have a good day. :mad:
