They are a collection of my own experiences of using a Chaparral Monterey Model 70 and a Monterey Model 55. 1.2 CONTACTING CHAPARRAL COMMUNICATIONSWorld Wide Web: Electronic Mail: Telephone: Fax:
InfoFAX: Snail Mail: Receiver Warranty Service Center: 1.3 MONTEREY SATELLITE RECEIVERS1.3a PASSWORDS FOR ALL MONTEREY RECEIVERSThe factory default password for all Chaparral Monterey satellite receivers is [2], [3], [4], [5]. When your receiver asks for a password try the factory default first. If the factory default password does not work, or if you have forgotten the password that you put in, you will need to do a password override (see below). 1.3b PASSWORD OVERRIDE FOR MONTEREY MODEL RECEIVERSTo override or delete the password on Monterey receivers, when you are asked for the password, instead of entering any numbers, press [SATELLITE], [MSG], [TEXT]. This will permanently remove the password from the Monterey. If you desire the password protection, you will have to go back in the Receiver Setup and re-enter another. If you have tried the password overrides, but everything is still coming up locked, it may be necessary to master clear your receiver (see below). 1.3c MASTER CLEAR INSTRUCTIONS FOR MONTEREY RECEIVERS
b. Audio subcarriers c. Transponder frequency, bandwidth, TI filters, etc. For Monterey 35,50/55,70,95/95,100c Receivers: Move the dish to the 5000 position - this is usually the west limit. The reason for doing this is that the Monterey will default to 5000 when it's first power up after a master-clear and expects this to be the west limit. If you have a very high count acuator (high pointing accuracy) you might want to point the dish due south (half way point between east and west travel) this will allow your satellite position count to go range from 0000 to 9999. Unplugging the receiver and reconnecting the AC power, then turn the receiver on using the front panel power key. This performs a restart on the receiver memory system. From the standby mode (off), press and hold on the: Continue holding the keys, then press and release the front panel power key to turn the receiver power back on. Continue holding the keys until "MASTER CLEAR" is displayed on the front panel. This should only take a few seconds. You must now restore the database from the list you made of programmed items. The receiver is now restored to the factory database, any custom programming you have done will have been lost. The factory default password is [2], [3], [4], [5]. 1.3d CLEARING TIMER EVENTS FOR MONTEREY RECEIVERSYou cannot stop an event once it starts. If the hours have been set incorrectly, i.e. 60 hours, the timed event must end before other events can happen. The easiest way to cancel the event is to set the year ahead and save it. Then go back and reset the year to the correct date. This will cancel out the timed event and allow others to work again. 1.4 CURRENT EPROM VERSIONSTo find out if you have this revision, go to MENU 6 , move the cursor to the line that says ON SCREEN PART NUMBER and press enter. Look only at the first 6 digits in the long number that comes up at the bottom of the screen (ie. M55-123456xxxxxxxxxxxx).

The default database contains many items that you may not be using these may be deleted to free up memory for use by something else. By following these procedures you will provide the most memory available for your custom programming and ensure that none of the default sub-carrier audio setting are stored. 2.1 DELETING THE DEFAULT SATELLITESStart by performing a master-clear as described in this FAQ. Set your East/West limits. Go to the Satellite definition menu and erase all satellites East and West of your current location. Using the Satellite Definition menu add a new satellite - for an example let's add Galaxy-IV C-band.
Format: FOUR GHZ Satellite Type: GALAXY 4 Go to the Satellite/Channel setup menu and set odd numbered channels to Horizontal (101) polarity and even numbered channels to Vertical (172) polarity. Change the channel to 24 (CBS NEWSPATH) Locate and store G4's position Go to Satellite menu and delete the only other satellite in the database besides G4. Repeat the same procedure for the rest of the satellites you want entered. Using this procedure will guaranty that only the minimal amount of memory is used and no additional audio sub-carriers are stored without your knowledge. Anything that is changed from the default setup will use some memory. ITEMS THAT USE MEMORY IF CHANGED

Dish Position Polarity Favorite Channel Groups Favorite Channels Satellite Name 2.2 DELETING AUDIO SUB-CARRIERSYou may delete audio sub-carriers that you are no longer using or don't want to provide additional memory for storing custom programming. Select the satellite and channel on which the audio subcarrier is located and select the subcarrier you wish to delete. Go to the Audio Menu the tuning values should be displayed for the subcarrier you wish to be deleted. Set the mode to STEREO (even if it's a mono signal) Tune both the LEFT and RIGHT Frequencies to 6.80 MHz. Set the stereo/mono mode to MONO. Set the Audio Bandwidth to NORMAL. Set the Audio Level to NORMAL.
SETTING POLARITY Option 1 Option 2 C-BAND transponders on all domestic satellites are always 36 MHz wide, the Monterey uses a default setting of 26 MHz. I set the all the non-encrypted active channels on C band to 36 MHz - doing this however uses some memory - it would be far better if the default stored in the EPROM was 36 MHz for the FOUR GHZ format. The exception to this is some of the weaker Atlantic satellites (ie. Intelsats) where a narrow bandwidth setting helps to clean up the video signal. For VC2 encrypted channels setting the video bandwidth to 36 MHz does not seem to make a difference. KU-BAND transponders vary in there bandwidth - in general most full transponder work good with a 26 or 36 MHz settings and most half-transponders work well with a 14 or 20 MHz bandwidth setting. You will need to adjust this on a per channel basis, as opposed to per satellite, because transponders on any given Ku stallite can vary between half and full transponder. TI-FILTERS can also be used to further narrow the video bandwidth on weak satellites. But sometimes they tend to add more noise to the picture. By using the video shift feature in the receiver setup menu you can adjust the video frequency +/- 99.9 MHz which means that you can tune C band 3.6001-4.2999 GHz and Ku band 11.6001-12.2999 GHz.

Another solution is to let the snow build up and then take a broom and sweep the snow out of the dish, this works okay for removing snow but not ice... provided you have someone willing to go outside to sweep the dish out!. What you really need to do is heat the surface of the dish to prevent snow or ice from accumulating in the first place. This can be done quite easily with "heat tape" or "pipe wrap" found in your local hardware store. Since snow usually only occurs at higher lattitudes you may only need to heat the lower half of the dish surface, but if you experience a good deal of blowing snow you will probably want to go ahead and heat the entire dish surface to some extent (maybe reduce the amount of heat tape on the upper half of the dish). You may need to do a little experimenting to determine what pattern and how much "heat tape" to use to melt the amount of snow you receive in an "average" snowfall. Always apply the heat tape on the backside of the dish whenever possible. A pie shape pattern (dividing the dish into 8 wedges) might work well if you are doing only the lower half of the dish, whereas a spiral pattern might work better if you plan on doing the entire dish surface. You may also need to disable the built-in thermostat controls, since they usually turn off at 35 deg F. PAINTING THE DISH
4.1 FOCAL LENGTHMeasure diameter of dish, square that figure. Find the depth of the dish, multiply by 16. Divide the squared diameter by the depthx16 and you will have your focal length - measured from the hub of the dish to 1/4" (0.25") inside the feedhorn throat.
dish depth: 21.5" x 16 = 344 divide: 14400 / 344 = 41.86" focal length 4.2 CALCULATE AZIMUTH AND ELEVATIONLOdish : Dish Longitude
Azimuth = arctan[ tan(LOdish-LOsat)/sin(LAdish) ] + 180 (degree) for elevation it is better to use an temporary variable, say B: B = arccos[ cos(LAdish)*cos(LOdish-LOsat) ] and Elevation = arctan[ (cos(B)-0.15126)/sin(B) ]
This information pertains to the Monterey 35 & 30, Monterey 55 & 50, Monterey 70, Monterey 95 & 90, Monterey 100C satellite receivers with on screen part nuber 020104 or less. To find out which version you have, go to MENU 6 , move the cursor to the line that says ON SCREEN PART NUMBER and press enter. Look only at the first 6 digits after the M95- in the long number that comes up at the bottom of the screen. If it reads 020105, then you already have the current version (the Y2K fix) which was released in December of 1999. If these first 6 digits is a number lower than 020104 you'll need the new eprom kit that fixes the Y2K problem. If you have one of these systems and use the timer functions at this time you probably already know that the timers are not working properly. Everything else works, aside from the timer nothing else is day/date dependent. The problem is that as the year rolled from 99 to 00 and the day changed from Friday to Saturday the Monterey receiver change the day to Sunday January 1, 00. The common fix (workaround) of changing the date to 72 doesn't work for this firmware version, I have found that setting the year to 56 *seems* to work (also year 28 appears to work) properly... that is until the updated eproms arrive!
