For instance, 95.3MHz shows 61dBu in the apartment on channel. The 95.5MHz racket shows 53dBu, and at 95.1MHz it's 49dBu. If you look carefully at the SDR spectrum plot a few posts back, you can see that even on it, the upper and lower "rackets" are slightly different in strength, with the upper one a tad stronger.

During the "Fresh Radio countdown" things were rock solid, then, just a couple of minutes before 7:30pm things fell apart again. Why that happened, I don't know, but as I'm typing this the analogue / digital switching is happening every 30 seconds to 1.5 minutes... really annoying....

95.3MHz "Fresh FM" Hamilton seems to have nixed the problem with the on / off cycling of the HD streams.

One side effect though is that at the moment, HD2 isn't labeled "AM640", but instead the top line is "HD-2" and the second line "CING-FM".

Shouldn't this finally say on the top line "AM640" and the bottom line "CFMJ"?

I've noticed when traveling in the U.S. that the additional HD streams have been labeled with their respective callsigns and not the originating transmitter callsign.

My MotoG smartphone gets FM radio (hint: cut off the earbuds from an old set and you can listen through the phone speaker(s) and that serves as the antenna). HD app possible for a smartphone?

I wonder what the CBC management thinks about HD? Can't wait or do they want to avoid possible pain?

What I do know is that previous government was unfavourable to CBC funding and dropped it by $105 million, and nominated to the Board persons affiliated with the governing party. (I hope moderators will see no political comment or any bias in that presentation of published facts. Readers can "fill in the blanks" for themselves.)

Soooo, what will Mr. Trudeau's party want to do?

Sure would be nice to have more audiophile-like classical music receivable at home. Pity 96.3 plays what comes across as MP3 (or worse) compressions. Shame on them. Maybe HD will change them.

Data point:

Hamilton CING 95.5, both channels strong in mid-Toronto (with 10 foot yogi aimed at Buffalo).

My impression is they've skewed the bass up to delight folks in SUVs and Jeeps. Not my cup tea.

Since I have CD's with what they're playing currently, the bass, although sounding heavy, is consistent with the CD's. That's the way of pop music currently.

Slightly OT:
Listening to classical or vinyl for that matter, the base is a lot less, and in most cases, natural. Going to a live concert of classical music will correct references people have to tonal balance. :) (that discussion of HD tonal balancing can be moved over to the HD general discussion thread).

Perhaps pop music is no more exaggerated than the CD - I have nothing to compare. But 95.3-2 male announcers are unlistenably bassy on my carefully mic room-equalized music system.

As I've mentioned before, the most immediately obvious benefit of HD on an already high-class radio system is the extended bass. So, stations that are "gilding the lily" in bass come across as bass-heavy in HD.

So back to this thread, with pop content on music and booming announcers, 95.3 adds nothing to my Canadian radio listening opportunity.

95.3MHz HD1 matches very closely with the analogue in the bass response area. The mic EQ is often a function of how the station producer want's the "station sound" to be. And yes, the tonal quality of HD2 is bass heavy also, whereas the AM is thinner at the low end.

We need a good man like Cam to break the news to the station engineer!

Do you volunteer?

Joking aside, there has always been the problem of engineers using table radios to do recording mixes. Or is it a myth? But here engineers really are facing a choice, eh.

I've been keeping an eye on the CFMI HD transition, which as those in Vancouver have observed, has not been without teething. Corus moved CFMI and CFOX from the Selkirk/Rogers site on Mt Seymour to their old site which is about 1/3 the way down lower on the mountain which cost them coverage up the Fraser Valley. How this is going to flesh out with HD will be interesting to say the least.

On the CKNW sub channel, the levels are lower, and there's around 30 seconds of delay. I too have seen the random unlock occur both in North Delta and Richmond, both place have proper rooftop FM antennas, so it shouldn't be for lack of signal.

The big question is: are we only going to see them fill sub channels with their AM talkers or are they going to follow what's happening in the Seattle market: exclusive content (like KING, KJAQ, KUOW)? If it's just their ability to make CKNW sound better down town, there isn't going to be a rush by the masses to go out and buy a receiver and it's DAB all over again.

Now we also have the SCMOs that could be moved to sub channels or new ones created. The recent community stations in Surrey that broadcast religious programming could also be located on sub channels...

CBC in Vancouver has 5 FM stations in an already tight short spaced dial, 2 are class C's the other 3 probably class A's. Given that the Class C's could carry 3 additional channels each, that would allow them to transition the class C's to sub channels, and provide more services with an overall reduction of operational costs and better coverage than the class C's. How could CBC's brass not like this?

95.3MHz "Fresh FM" from Hamilton is not in HD at the moment.

Early this morning the HD was cycling again...

Seems this is something they need to ferret out.

Edit: HD Back on. No "AM640" title on HD2 at the moment, but the AM640 audio is there.

Since my post above rolled beyond the edit time frame... :)

Those listening to 95.3MHz "Fresh FM" from Hamilton might encounter periods where the HD is not running.

Found this happening today. On a trip into downtown Hamilton on the bus, I had HD all the way. On the return trip, the HD vanished at some point while the FM analogue remained strong and stable.

I suspect teething problems at the moment, and that would also explain why they're no longer mentioning the HD2 signal on AM640.

One correction to that story: CING-FM is NOT a low power signal... it's a blowtorch on 95.3MHz. :)

I had the HD signals up on Stratford a couple of weeks ago...

Looks like CKRY FM (Country 105) in Calgary is broadcasting an HD Radio stream now. While I don't have an HD Radio-capable receiver, my Grundig G8 shows a signal of 17dBu / 5dB when tuned to 105.3 or 104.9Mhz, and the static is louder. Adjacent channels to other stations show the expected 0dBu/0dB signal strength. This was tested in my basement though, which is why those numbers seem a bit low. That said, when I checked a few weeks ago, this wasn't happening.

Anyone in Calgary have an HD Radio to confirm?

Also it will be interesting to see whether CKRY carries a second feed, and what that station might be if they do.

More than likely it would be CHQR (AM770) as that's also owned by Corus Entertainment.

Again, this is speculation as I haven't actually heard how an analogue radio treats the noise from an HD stream before, but even on my G5 radio it seems something is different with the adjacent frequencies of CKRY vs other FM stations.

I still have that Personal Telecom DR-101 that was used for DAB reception.

On it's FM section, the digital "racket" can easily be discerned on each side of CING-FM Hamilton's HD signal, so that's two radios that I can determine the racket on. The DR-101, while scanning, will stop on the racket. It's signal meter shows full scale (because I'm close to the CHCH tower).

The Grundig Traveler II G8 also stops on the racket.

To give someone an idea of the signal strengths found, with the Grundig CING-FM will be 60dBu on it's main FM signal. The racket 46dBu.

Keep in mind those range of values when tuning weaker stations.

The G8 does indeed stop at the adjacent frequencies. Moving the radio around in my basement, I saw signals up to 22dBu on these frequencies as well. Tuning to 105.1 I could get up to 40dBu in the same spot
