Aye, 2 meter or so,  Some muni frequencies are 130s, 170s,, 200s, etc.  However it changes from area to area.

many times airports and places like that require regular users to have a "transponder" (similar to a "pikepass") to identify who they are and how often they come and go.

Just my wild guess that it is something like that!

My RTS has something similar, just a different shape.  I was told it was for the antenna for the transit driver to communicate with their office.

I have toyed with the idea of trying to mount a wifi antenna in it.  Just not much motivation for me since I use a cellular wireless card and have a signal most places I go.  And if I didn't, I likely wouldn't have a wifi signal available either.

I had three on mine, one up top, and the two you see on the cap, pulled 3 business band radios out of it. It did have a 10 inch S/S pig tail antenna also, guess Harran coach really was in touch with it's drivers, before they slammed the door shut on the drivers Angry.

Reel -

Van got it right - it's a business band radio antenna cover.

Extremely common on transit buses, lots of communications between dispatch and the fleet on the street.

Check it out a little closer, as most are fiberglass or plastic.  If so, the idea of using it as a cover for a GPS antenna is a good one.  If it's metal, a GPS might not be able to obtain a signal.

FWIW & HTH. . .

Yup, radio antennae cover.

And that isn't the front cap your coach left the factory with.

Lots of MC8 had a slope top riveted on to hide the hump, trying to fool the customers that it wasn't an "old" bus.

This is as good as any: Compare the MC8 to the MC9, you'll see what the slope top was imitating:

The stock MC8 has a roof line that had a marked hump behind the driver/entrance door.

This was a continuing styling mimic of the trendsetting GM Scenicruiser, and the following MC7, and the GM 4107/4108/4903/4905.

All of these had windows in the hump, but leaks were a pain.

The MC8 maintained the visual cues, but were solid humps, no windows.

With the MC9, the move to taller windshields and a flat roof front to back began.

Towards the end of the useful commercial life of the MC8 line, towards the turn of the millenium and beyond Y2K, the 2nd/3rd tier operators started installing dress up kits on these older coaches, as the customers were becoming savvy to the fact a hump in the roof meant old bus. To be fair, it was also an easy way to fix the fibreglass hump if it had been damaged, or was cracking due to sagging supports beneath or otherwise the ravages of time.

All those modernizing facelifts from R & M, and others, continue this opportunity to this day.

My MC8 has a stock roof hump.

reelnative, in looking at your pics again, your MC8 appears to be of the last batch that had the square windows front to back, no "D" window behind the driver and no slanted roof brace midships.

Find a unit number for your coach, either a plate riveted to the ceiling near the driver or back in the rad fan compartment. I'm doubting it is a '76. That style of side window was just before MC9 production started, 1978 or so.

Yup, BK, that's how they did the last of the MC8.

For what reason, I have no idea, IIRC, there weren't that many built that way before the switch to the MC9.

Those MC8's square windows were all shorter than the MC9.

My parts book is not at hand, or I'd find the build date for those.

reelnative, got a unit number for us?

Josh, thanks for the compliment Smiley, I have been told that I am good with PHOTO shop Grin. Yup mine was built for HARRAN coachways ( Comac L.I, unit 601, then went to some tour co. in chicago, were it was purchased through an estate auction by the PO. The extra radios were to stay in contact with the other tour co's they supported i believe, found this out after exploring the prom chip that was installed in it. Atlantic City for one, the N.Y.C sports teams club house's (mets, Yankee's, Islanders) as well as 12 other tour company's names were also displayed. If any one want's them (antenna covers), I will send them out to you once they are removed ( mid summer) F.O.C.

reelnative, we/you need the unit number. It's on that same plate.

The serial number in those days was determined at some point in the ordering process of the coach, the Unit number determines when in the run it was built, and is the number used throughout the maintenance and parts manuals to differentiate the coaches and their quirks.

For instance, there were EIGHT different air schematics for the MC8 model run.

Your unit number should be something in the low 30 thousands, your serial number is 800 and 900 higher than my two 1975 coaches, so it does correlate to 1976.

Now I'm really confused...maybe I remembered the years wrong for the square windows? Or someone playing monkey business with the coach build plates?  Where's my manuals....

happy coaching!

I have to say those pictures bring back memories.  I grew up in Ottawa and spent a lot of time on Voyageur buses as a kid.  We toured all over eastern Canada in them.  I have distinct memories of sitting in the jump seat behind the stairs on an MCI that was just like mine, watching the driver stir the 4 speed shifter on a trip from Ottawa to Perce, in Gaspe, Quebec. where part of my family is from.  Just fantastic. 1975, would have been an MC-8.  Even then I wanted to drive a bus!
