Today I cancelled my order for two CM-7000s from Solid Signal and placed an internet order with Summit Source. At the time I placed the order, the web page indicated they were in stock. I called Summit Source and the man I spoke with said that they have a FedEx tracking number for their order of 1200 with a delivery (to Summit Source) date of Fri May 23. They currently have customer backorders totaling 400, which means they should have plenty for a while. They will ship backorders first so my order will ship on Tue May 27 since Mon is a holiday.

Also for the record, he confirmed that Summit Source charges the cc immediately upon order, not shipment. Solid Signal doesn't charge the card until the order ships.

And that's a bad thing?

Solid Signal is a very reputable company. I think I'd rather pay them a few extra bucks than take risks with most of these other outfits being mentioned around here.

I never said Solid Signal isn't reputable. I have purchased from them in the past and have a large order with them right now. I switched the order to Summit Source for two reasons, less expensive and seemed to have a better idea when they would have stock. What have you got against Summit Source?
post #275 of 1483
I have had a CM7000 order "In Process" at Solid Signal since 4/29, and today it changed to "Shipped". Hopefully this means the logjam has cleared for a lot of the orders wating for that slow boat from Bulgaria.

I'm only annoyed with the delays because of the way the NTIA coupon program is set up. If you can't get the box you want because of shortages, there are two possibilities:

1. If the company doesn't charge your coupon until they have stock to ship, the ridiculously short 90-day expiration means your coupon may expire before the box is available.

2. If the company does charge your coupon before they have something to ship, NTIA's no-refunds policy means the company you ordered from holds your coupon hostage (e.g., MaxMedia/Memsen). If you don't want to forfeit your coupon you're forced either to wait or possibly to accept an inferior substitute.

I'd be more willing to put up with delays if the coupon program had been more flexible. I'd even settle for $30 coupons instead of $40 if they'd last 6 months instead of 90 days.

Anyhow, Summit Source's CM-7000 Web page is now claiming they're in stock again, so maybe we'll get our boxes before much longer. I took the plunge and ordered one Wednesday.

Update: Summit Source said they shipped my box today - and they gave me a tracking number! (Something etronics.com never did for my Philco.) UPS says I should have it Friday. If so it'll have been only 9 days. Not quick but hardly 5 weeks either.

I concur. I've ordered several items from Solid Signal and have been generally happy with their service and value. But their CECB prices seem quite out of line with their competition.

QD9 may be a NPN transistor with a buffer cap on its collector (CD28). Its output goes to impedance matching/filter network RD61, 62, and CD29, and is finally AC coupled to the coax output through CD30.
RA7 may be necessary for signal integrity to cut down on ringing, or provide additional pull up or pull down current.

With one of these in hand, I could probably have a working solution in an hour or less.

I had a thought...many manufacturers build their products using designs straight from a chip's "application guide." Perhaps checking the manufacturer's web site for the chip will yield an example circuit for the digital audio out, with suggested component values...

Just to let others know, I ordered the CM-7000 from Solid Signal on 5/8/08, but heard nothing from them about a backorder... After I sent them an email, they were quick to tell me that the boxes would arrive soon and would ship on Friday. True to their email, my box did ship on Friday, but I wished they had let me know that there would be a delay in the shipment, rather than my having to ask.

As soon as I get the box, I'll compare it to my Zenith and let everyone know....

My backorder at Summitsource finally just shipped (got an email confirmation on shipping with a tracking number 20 minutes ago). My order had been backordered since April 17th
post #283 of 1483
Just opened my front door and the CM-7000 was laying up against it! Wow.. just had received shipping confirmation hours ago and it is here already! The security tape on the box was cut and the box was held together with several rubber bands. Looks like the post office played around with it. They *lost* my DTV converter box coupon and the NTIA REFUSED TO replace coupons that were never delivered. If it were not for a guy I work with to give me one of his coupons, I'd have a big paper weight next year. Maybe Summitsource checked out a handful before sending them out. I knew I was at the top of the backorder list.

So I hooked up the receiver and to my surprise it picked up 15 channels (6 real channels with subchannels) with an unamplified Radio Shack bowtie antenna on top of the TV. Must be the newer gen digital tuner (when compared to my old HD capture boards in my PCs). My PC-based cards are hooked up through a large roof antenna in the attic (with Winegard PR8800, CM7777 pre-amp and CM distro amp) and that system cannot pick up one of the channels I picked up on the CM-7000 DTV converter box. The tuner is definitely more receptive in this box. It's a perfect picture for that one channel at only 22 to 35% signal! The remote looks like it will take a little getting used to, but I'm a happy customer so far. As I play around with it and see how fast it channels channels, I am just more impressed. Glad that 'ol 27" is staying with us til all its inputs die (s-video is the only input still working after all these years, not even RF input works)

Summit Source shipped my two CM-7000s today as promised. Glad I switched the order from Solid Signal; saved ~$22!

Connected the CM-7000. I have an outdoor antenna mounted on the chimney - maybe 40 feet high. Had good reception of Philly analog here in Reading, PA.

The only Philly stations that are being picked up by the CM 7000 are KYW and ION. I think KYW is VHF and ION is UHF. I incrementally turned the antenna and scanned for new channels. Did not get any of the other Philly stations. Figured if I got KYW-3, I would get the rest, because KYW was the weakest analog reception.

So, I am disappointed with the variety of channels. However, the picture via S-video on KYW is better than from my satellite dish.

Does anyone have any ideas as to why I am getting so few stations?

Are you using any kind of pre-amp? If not, you will need a CM7777 or similar to pull in those Philly stations. I'm assuming you have a pretty good antenna. The 7777 works well on weak signals if you have no powerful local stations. You should be getting the York area stations unless you have terrain or ghosting/multipath issues. I'm really toying around with getting one of the CM 7000 boxes. I love the reception of the Zenith, but I really want to have the S-Video option of the CM.

post #288 of 1483
At 5 a.m., I attempted to scan in more channels. I was able to add 29, 48 and 57 from Philly and 69 from Allentown.

Yes, I have Pre-amp as part of the Home Theatre set-up.
post #289 of 1483
From Reading, Allentown is roughly ENE while Philadelphia is ESE. Are you picking up both at the same time? If so you probably need to aim your antenna more towards Philly for reliable Philly reception.

Also it would be helpful to know what sort of antenna you have. Currently all Philadelphia digital stations are on UHF, though this will not remain true.

I received two CM-7000's today from Summit Source. Both worked well and received all my local digital signals (through a DB8 and CM-7777 preamp) upon installation. After four hours, one unit failed (may be power supply, as no power LED is lighting up on the unit). Wrote Channel Master Technical and Customer service this afternoon to see if they can issue an RMA # and instructions for return. Hope the second unit hangs in there.
post #292 of 1483
Looks like summit source raised the price $6 to $75 for a box that should be $50 we are paying much more just because we have the coupons.

I believe the auto powerdown is there to place the unit into standby (orange LED) mode from full on mode (green LED). In the failed unit, the power LED simply would not light up at all (when plugging in, it should go red for boot up, then yellow for standby). I also measured the power supply outputs (12v, 5v, and 3.5), and they were either way off or not readable at all.

Guess it's a good thing I got my order in last week before the price went up.

Mine arrived today. I've hooked it up, and I'm pretty impressed with the thing. First thing I noticed when I opened the box: instead of the typical 3' coax cable with push-on connectors, it's coax has screw-on connectors. Nice touch. I hate push-on connectors; my cats keep pulling them loose.

Since it doesn't have pass-through, I hooked it up behind an old VCR that doesn't play tapes too well anymore, but serves fine as an NTSC tuner. I just turn the VCR on for analog TV and (since all VCRs have pass-through) turn it off or hit the TV/VCR button for digital TV. The VCR is hooked to the TV via composite video and the CM-7000 is hooked up via S-video.

This unit may have been a return: when I hooked it up it already had a few channels from some faraway place stored in its memory and reported "no signal" when it couldn't find them. This panicked me for a moment, but a simple channel scan put everything right.

Sensitivity is comparable to my Samsung DTB-260F HDTV receiver. KDFI-27 comes through fine on both the Samsung and the Channel Master even though it pixellates a bit on my Philco CECB.

Another thing it has in common with the Samsung is that neither one can figure out KLDT-54's audio. The Philco is the only box I have that can decode that station's sound. KLDT's just a shopping channel, though, so it's no big deal.

Update: I think I figured out what's going on with KLDT's sound. DTV stations can broadcast multiple audio streams - typically for multiple languages. The box automatically selects your preferred language.

KLDT is "broadcasting" three audio streams, but is flagging all three as English! Worse, only one audio stream actually contains anything. So the stream the box selects appears to depend on unpredictable factors like the box design, the phase of the moon, etc. And there's only a 1 in 3 chance your box will select the working audio stream. KLDT got lucky with the Philco but not with the CM-7000.

The fix is easy: I just push the "audio" button on the remote until the sound comes on. But in doing so, I discovered a minor problem with the CM-7000: it doesn't remember your audio selection separately for each channel. So if I switch the audio to stream 2, KLDT-54 starts working, but KDAF-33 switches to stream 2 also, and I get Spanish - or nothing at all if there's no Spanish sound for the program.

In contrast, my Philco remembers the audio setting separately for each channel. If I switch KLDT-54 to stream 2, it doesn't affect KDAF-33 and vice versa. But when I return to a channel I've changed, it remembers my selection from earlier.

The channel setup is the best of the three. When scanning you can either clear the channel table or you can scan to add channels to the existing table. You can then flag any channels you don't want as "deleted" so CH +/- on the remote will skip them. Unlike the Philco, you can delete subchannels, and the channels aren't "really" deleted; if you change your mind you can just go back into the menu and unflag them. (With the Philco you have to either rescan or tune in a deleted channel by its digital channel number to add it back.) The CM-7000 also lets you select some channels as "favorites." The Samsung's channel setup is similar, but I like the CM-7000 better. The Samsung's "favorite" button just moves to the next higher "favorite" channel, but the CM-7000's "favorite" button brings up a list of all the "favorite" channels that you can navigate with the arrow keys - or you can switch to a list of all (nondeleted) channels!

The only drawback I've found with the channel setup is that you can't tune to a channel that wasn't on the original scan - even if you know the digital channel number. I guess that's why "deleted" channels aren't truly deleted: if they were, you'd have to do an update scan to add them back, and you'd get them all instead of just the one you want.

The S-video picture quality is excellent. So far on HD broadcasts I've seen none of the NTSC artifacts ("rainbow ties," etc.) that are common when using composite video. (I did see some artifacts on an SD broadcast, but I suspect the video was transmitted that way. If it were a problem with the CM-7000 I'd expect it to show up on all the channels.)

My RCA universal remote controls the CM-7000 with cable box code 034 (Pioneer - just like the manual says). The only problem is it lacks many of the functions of the CM-7000's own remote, including volume! The RCA remote insists on sending the TV's remote codes when you use the volume or mute buttons, which could be a problem if you use a separate amp for audio instead of your TV. But that's a problem with the RCA remote, not with the CM-7000. There are undoubtedly other remotes that would work better.

The aspect control is better than the Philco in two ways. First, it's one-button access. (The Philco makes you go through the setup menu to change the aspect setting.) Second, it has two zoom settings. Zoom 1 is a "partial" zoom; sort of a compromise between letterbox and the full-screen Zoom 2. This should be useful with TVs that have a lot of overscan.

Overall, I found it well worth its somewhat higher cost. The only feature it lacks that it really should have is pass-through. (Well, and for $69, er, $75, including an S-video cable would've been nice, since S-video is its major selling point )

I received my CM-7000 today from Solid Signal. Initial tests shows that the box performs very well. As far as sensitivity, it is VERY close to my Zenith DTT-900. I tried connecting both to the same antenna and seeing how well the weak stations came in. Both boxes were about to pull in Channel 10, KGTV San Diego (I live in the LA area). The signal was on the edge and both boxes froze up a lot. The Zenith froze up a little less, but because the signal came and went, I can't be sure if the Zenith is a tad better OR when the Zenith was connected to the antenna, the signal came in a tad better.

The photos of the box make the box look like cheap plastic, BUT as I hold it, I can see it's made of metal and feels solid. The image is also great!!!

Compared to the Zenith...
THE GOOD:

S-Video out

Program guide is more than just now/next, it's 12 hours of information ...

My RCA Universal Remote as Pioneer Cable Box #034. With the RCA Remote, volume changes the TV volume, not the box's output.

THE BAD:

The CM-7000 remote can not turn off my TV.

OK, it costs $20 more than the Zenith

I couldn't buy it local with a coupon.


PHOTOS (More to come later)

Here's the box sitting on my Zenith DTT-900 converter.




In the back side view, you can see the unused RCA connection, the S-Video connection, the Channel 3/4 Switch, and other connections.


The remote has a lot of buttons, but 4 of the buttons are not used.



More updates to come, stay tuned...

After reading dozens of pages of info on CECB's, I'd decided on the CM-7000...
Below is a copy of the correspondence I had with Summit Source, the timeline starts from the bottom up between the bars...

====================

Terry,

Regarding your question below...

We can beat the Fry's price, since Fry's is NOT able to accept the Government rebate coupons... and we can!

$68.95 - $40 rebate = $28.95 + shipping

Here's the link:

Hi,

Will you price match the Channel Master CM-7000 selling at Fry's during this Memorial Day weekend sale?

Their price is $59.99.

The ad is on page 6 of a Fry's promotion, found here:
http://ads.ocregister.com/interactiv...0523082345.pdf

The CM-7000 is located in the middle of the page.
You might need to zoom the pdf to 100% or more to see it clearly.

If so, I'd like to use both of my coupons for two of these units.
I will order immediately after your confirmation.

Thanks,
Terry

===========================

Long story short: Summit Source advertises they will "price match", and "we will not be undersold".... it's bull.

I wonder how many people would fall for their BS retort?

My tax dollars are paying the $40 coupon reimbursement.
Price matching this example would mean I pay $19.99 per unit of the Fry's advertised $59.99 price.

Wholesale prices on these units are the same for every source.
The fact Fry's can sell it for $59.99 without a coupon is proof that everyone who accepts a coupon and sells it higher than $19.99 is in effect charging more than it's worth.
It shouldn't matter where the money comes from if indeed Summit Source cared to honor their advertised price match.
Summit Source is taking advantage of the public by undue profitting on this government sponsored program. This was of course before they raised their prices even further since Memorial Day weekend...
Yes, they have the right to charge whatever they want.
But, add the false price match advertising on top and I'll take my business elsewhere, thanks.

Summit Source has lost potentially hundreds in profit from my future purchases by not honoring what amounts to $10 a unit on price match principle alone. That's a stupid way to run a business, folks.

Solid Signal is of course doing the same thing... gouging the public even worse on this unit.

And, they'll keep doing it as long as you allow them to...

If anyone locates a reasonable source that accepts the coupon, please post.

Data Action @ $68.85+ship (but unclear if in-stock)
Given the apparently strong demand, I wouldn't be surprised if they follow suit with a price hike.
post #298 of 1483
that is the business of retail, supply and demand. They can charge any price they like but that doesn't mean you have to buy from them.
post #299 of 1483
Received my CM-7000 yesterday and have given it a functional checkout. It seems to give slightly better image quality (composite) than our Artec. I don't have an S-Video cable yet. Sensitivity is on a par with our Sharp 1081P HDTV and the Artec. Since we're not in a deep fringe area, small sensitivity differences between the three are hard to judge. All three are receiving channel 12 off the back of the antenna at 60 miles or more distance this morning. We are equipped as described in our post #236. The meter does give higher readings than our HDTV or Artec, but who can say whether their calibration is comparable without checking them with lab equipment?

I find that my concerns voiced in post #236 before I had ever touched a DTV converter are satisfied, although it was difficult to envision the effects of the various aspect selections before having tried them all.

Bob Diaz's excellent photos show the hardware as it really is, and it looks far better than in previous photos or illustrations. I particularly like the content and convenience of the INFO display. It includes the sensitivity meter. The aspect ratio selection with one button is fast and convenient.

I have one big disappointment. The font used in the INFO box is small, and is displayed all wavy and distorted on our Sony 36" WEGA CRT set. I have major difficulty trying to read the channel number.

Fortunately got my order in to Summit Source before their recent price hike. I consider the extra expense of the CM-7000 to be worth it in view of the quality improvement its S-Video output is sure to provide.
post #300 of 1483
tgorle,

You're correct about Summit Source's claim to price match - it is not accurate in all cases.

Fry's is having to sell their stock of CM-7000 at or close to their cost because they aren't eligible (perhaps missed the deadline to sign up) for the NTIA coupon program.

Will Summit Source will match the price from another dealer that is able to accept the $40 coupon?
