Notice to all Buzzboard readers & posters: A requested server migration took place Saturday evening. Unfortunately, I did not re-point my DNS records to the new server until roughly 7:45p ET on Monday, November 12. As a result, any posts and new user registrations occurring between the nighttime hours of 11/10 and approximately 7:45p ET on Monday, 11/12 have been lost.

This was unavoidable, and the longer I waited to re-point to the new server, the greater the number of posts that would've been lost.

Please feel free to resubmit any threads / posts you created. They will NOT be lost this time! Many thanks for your patience these past couple of weeks while I've worked to migrate the Buzzboard to a more secure, more robust platform.

There was also MORE-TV, which I think just used to rebroadcast HBO? I can't remember which service had this ad, but I remember one of them featured a girl with one of the pay-TV logos on a t-shirt. I don't remember if getting a t-shirt was part of the campaign, but she stated that she would 'give you the shirt off her back', and reached down to the bottom of her shirt as the ad ended.

Wasn't channel 20 ON-TV for a while in the 80's?

So was this an encrypted OTA signal? It sounds like it died off once everyone one got wired for CATV

It was broadcast on Ch 31 Ann Arbor which was WIHT then (In Home Theatre). The transmitter was actually near Chelsea, with a satellite repeater on Ch48 in St. Clair Shores. At one time it was scrambled 24 hours a day. They used a much more secure system called SSAVI, then what was used for ON-TV.

After IT folded, both 31 and 48 would become independents, then HSN, before becoming PaxTV / Ion. I believe the channel 48 transmitter closed down shortly after channel 31's digital signal relocated to Southfield. The transmitter near Chelsea would become the new home for Lansing's WHTV, a rare instance where a station serving one market operates from a transmitter in another market (that originally served that market).

Nope, when I first dabbled into using antennas after decades in 2015, I was still able to receive the 48 transmitter, albeit in digital and broadcasting Daystar programming.

There's another example not far away: Toledo religious station WLMB broadcasts on RF 5/virtual 40 from a transmitter in far southwestern Monroe County, which is also in the Detroit market.


My furthest DTV tropo: KDKA Pittsburgh, Pennsylvania at 202 miles for three days in January 2017 and a night in September 2017 with only an Antennas Direct C2V!

I no longer maintain my RabbitEars.info DX listing.

Actually the transmitter is in Lenawee County, in Fairfield Township.

Not "encrypted" in the true sense, but "scrambled" using a sync pulse inversion technique similar to the Macrovision process used for VHS copy protection. Pirate descrambler boxes were abundant and cheap and could also be built by anyone with basic electronics skills of the day, contributing to the demise of the OTA pay channels.
Many of us remember (yes, admit it) catching a few fleeting seconds at a time of late night soft core pr0n by flipping channels and getting a visible image until the TV got unlocked again by the fake H sync signal.

Yeah, my parents were legit ON TV subscribers but I had a small Panasonic television that was pretty good at getting IT TV without the scrambling. I don't remember it being for only a few seconds at a time but it was a long time ago. I think they called it Adult Theater at night when they aired the soft pr0n.

Furthermore, Lenawee County is the only Michigan county within the Toledo market:

MORE-TV started out on 2.154 GHz MDS (multipoint distribution service) facility as single channel HBO unencrypted. In detoilet, it was first on the Book Building, then moved to the Renaissance Center ca 86-ish. Satellite receive location was first on a big dish and small microwave tower adjacent to a golf course on Wayne Road near I-94, and microwaved to the TX location(s).

The downlink location was eventually moved to WGPR on Jefferson, and microwaved to the Ren. Later, when they went to MMDS with the ITFS channels (see below), they went to a VERY expensive and not-so-reliable video leased-line-coax provided by MBT from 'GPR to the Ren. 'GPR always had a pretty impressive satellite downlink facility, since they ran so much stuff delivered that way. I recall most of what Microband wanted already had a dish pointed at the correct bird, and only needed another RX port and receiver.

There was a short lived similar MDS single channel installation in Pontiac on the PSB building downtown; it didn't work out though, and was shut down. Ditto Ann Arbor. They were kept in place and fired up once a year with bars and a test pattern to keep anyone who really wanted to do something with the frequency from getting the license.

It was owned by a company called Microband Corporation of America in New York City; they had installations in many large cities. It was leased to the 'MORE TV' people locally; they were located in Livonia....they were Microband's 'customer'. Microband eventually bought MORE.

Later, ITFS channels were purchased from the Archdiocese of Detroit (that was always a complete boondoggle, and I suspect merely an investment). I don't recall if all the spectrum came from A of D; there may have been others....U of D is rattling around in my dusty head. A of D towers and red microwave dishes are still on a few Catholic schools around town.....it never really got going well, though. It was first put in when I was actually attending one of the elementary schools.

Anyway, Microband bought them, then went to a multichannel system from the Renaissance. I recall it was 5 or 6 channels; 'HBO' was still on the higher power MDS freq it was always on. Receivers did some simple decryption; and required two different antennas due to polarization of different channels used.

Channels were eventually supposed to become wireless internet; I recall maybe Sprint being peripherally involved in that, then 'Speednet'....I think Bob Liggett has some interest in that. Nice idea, but cable 'caught up'.

Anything else needed? I know that MDS/ITFS/MMDS system then like I know my cat today.
