Motorola Spectra UHF Mods - capacitors leak

Motorola Spectra UHF Mods - the capacitors in older spectra tend to leak so it may be a good idea to replace them if they haven't already.

SYNTOR X Glossary

0x - The nomenclature "0x" is used to indicate hexadecimal numerical values. Hexadecimal is a base 16 numbering system. Hexadecimal values are easy to translate into 4 bit binary values. Here is an example:

HEXADECIMAL VALUE DECIMAL VALUE OCTAL VALUE BINARY VALUE
0x0 0 00 0000
0x1 1 01 0001
0x2 2 02 0010
0x3 3 03 0011
0x4 4 04 0100
0x5 5 05 0101
0x6 6 06 0110
0x7 7 07 0111
0x8 8 010 1000
0x9 9 011 1001
0xA 10 012 1010
0xB 11 013 1011
0xC 12 014 1100
0xD 13 015 1101
0xE 14 016 1110
0xF 15 017 1111
Calculator programs like the MS Calculator in Scientific view can convert between Hexadecimal, Octal, Decimal and Binary number bases.
Alternate Control Module - This is a style of mode select control head with push button mode selectors.
Binary - Binary is a base 2 numbering system. Digits 0 and 1 are used to represent binary values. Binary is most often used by computers, in this case as the Syntor X micro-computer or Syntor X 9000 micro-computers.
CEPT - Conference for European Postal Telecommunications administrations. This has to do with specific European compliance issues.
CH - This is an abbreviation for Control Head.
Clamshell Control Head - This is a style of mode select control head with a rotary mode selector.
Code Plug - Your program with all the frequencies and information that you save inside the radio (i.e. Rx and Tx frequencies, Rx and Tx PL/DPL, scan modes, Tx timeout timer, etc.).
Common Circuits Board - The Syntor X printed circuit board which contains the radio's audio portion of the transmitter modulation circuits, transmitter protection, receiver squelch and voltage regulators. The Syntor X 9000 circuit board is similar except it does not have any transmit audio circuits and it added an unswitched 5 volt regulator.
Conventional - Conventional radios are the traditional radios. They allow simplex or duplex (i.e. repeater) communications. Conventional radios are less complex than trunking radios. However, conventional radios allow greater interoperability with other conventional radio systems (i.e. there are no problems with incompatible trunking formats to prevent communications). Also see Trunking.
COR - Carrier Operated Relay. It may also be called COS for Carrier Operated Switch. This is a control used by repeaters. When the repeater receiver detects any signal, it asserts the COR as an output to send to a repeater controller. The repeater controller can use this signal to decide when to turn the repeater transmitter on.

ASTRO Spectra ASTRO25/APCO Trunking codeplug

ASTRO Spectra ASTRO25/APCO Trunking codeplug

For anyone curious, attached is a ASTRO25 9600bps trunking codeplug from a 1M ASTRO Spectra radio. Firmware R10.72.00 / N08.03.05.

I have several of these which I'll be listing for sale, with accessories, this upcoming week.

Review the codeplug. If the ASTRO25 featureset works for you, be sure to drop me a note once I post the items. Note the ASTRO25 featureset supports Linear Simulcast Modulation (LSM, CQPSK). This means it blows the socks off scanner performance, on these types of digital simulcast systems.

Motorola Spectra Amateur Radio Conversion

Motorola Spectra 110w trunk mount programmed for 2 meters. Notice the current draw on the ammeter. This radio makes a very nice base station with a desk mic.


Spectra Tips For use with Lab RSS R05.03.00

Spectra Tips For use with Lab RSS R05.03.00
Consider the following before trying any of these tips. When using the Lab software "Bit Banger" feature it is very easy to create an absolutely brain dead MLM, so be careful. Also, there is no guarantee that all tips will work with every Spectra. Forget about using this RSS with an Astro Spectra.
Bit Banging the model number
This is necessary if you want to clone a different model number Spectra's features into your radio.
The model number starts at location 0x6048 on the MLM and after location 0xB670 on the command board. After making any changes using the Bit Banger read the radio and then program the radio before doing anything else. When the clone operation is started you will most likely get a warning message that the radios features are different, tell it to proceed.
Now you have changed the model number in your radio to match your source, perform the following:
  • Load a codeplug from the "source radio" (the model number you want)
  • Connect the programming cable to your radio
  • Select clone from the menu, and in a few seconds RSS should tell you that your radio has been cloned.
But, before you do it, make sure that you're not trying to tell a dash mount 50 watt Spectra A5 that it's suddenly a 110 watt A9, it won't work.
