Thumbs up HD Radio Reception In Mississauga ON

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.

Default HD Radio

Just wondering if anyone has used an HD Radio in the Toronto area. I realize we donít have any local stations currently broadcasting in it, but I was thinking some of the stronger Buffalo stations might reach us here.
Iím 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.

Default Looking for a long range FM antenna

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.

Totallyr, roughly where in the city do you live?

I used to live in Dundas, below the escarpment, just off of 99 HWY, between Creighton and Overfield. I had a 48' tower with a 6 element Colban (made in Dundas I think, and that's a while ago ). From there, with the beam fed with 300 ohm shielded twin-lead, and a Sansui TU-9900 tuner, I could listen to WOMJ 104.3 with the beam west facing. Erie was more difficult, Buffalo was a shoe-in. The main problem I had was front-end overload from 95.3, 93.3 and later in years, 102.9. Those who designed the front-end of the receiver placed the RF attenuator AFTER the first RF stage. Using a TFM-2 double tunable FM trap, made by Gerald helped a lot. Also some wide-band switchable attenuation made the situation more manageable. It would have been interesting putting a McIntosh MR-80 on that feed line... But given a clear, un-tinkered with FM signal was an amazing experience.

So... Where you live will determine which stations you'll have problems with.
Depending on your tuner, you may or may not need to notch 94.7 and 95.3., as those two are in line more or less with Buffalo.

The tower also had amateur radio antennas for the HF bands as well as 2m, and a J-Pole for the 220MHz repeater.

Default HD radio Reception

I can receive 5 HD stations from Buffalo 93.7,94.5,98.5,99.5,102.5 .4 stations have HD2 second channel.I am using a 25 year old radio shack fm yagi that I cut off all the directors off the front to allowed it to mounted high in the attic so i have 3 driven elements and the rear reflector.I am using a Sangean HDT 1 off ebay.I am very pleased with the sound quality.

rob50312, how is the dynamic range of the digital audio on the HD1 feeds.

Have they regurgitated the analogue compressed audio, or left it alone and peak limit the loudest levels? I'm interested in how they're handling things. The DAB feeds I've been listening to seem to be a mix of analogue regurgitation, analogue STL feeds, and some direct digital feeds. Then... There's some feeds that have have the DAB feed sounding a right pigs ear terrible. Don't know how they're managing it, but hey, they must be working towards an engineering equivalent of the Darwin awards....

Cameron it would seem that that the dynamic range is being compressed on most stations except WNED the classical station.No need to do this with digital but the signal probably goes thru the same processor.The frequency response is better.I agree if they want HD radio to succeed it should sound exactly as a CD with no compression.
