Guide to Programming the HT1000 (this is a draft, will include
much more material, work in progress for comment purposes
only)

This guide is intended to be used by those who need to get a basic understanding of how
to use the Motorola RSS (Radio Service Software) to re-program their HT1000s for use
1
with MURS, 2M Ham (simplex and repeaters), and other VHF uses. The model HT1000
I prefer to own has a dtmf keypad to allow me to use phone patches with repeaters.
The HT1000 was chosen as the perfect SHTF radio, it’s old, well supported, there are
many accessories available for the radio. The HT1000 is mil-spec rugged as evidenced by
decades of use by Police, Fire and EMS personnel.
You should be familiar with basic computer skills, have a list of desired frequencies, their
modes, and understand how to connect the radio to the computer.
Background
RSS (Radio Service Software) is a program that runs on the PC that allows you to read
and write programming information to and from a radio (in this case, the HT1000). The
various sections within the program accept the frequency, tone, and other miscellaneous
data and then builds an “image of the flash memory into a “codeplug’ which can be
written to the radio. The RSS also offers functions to print the contents of the codeplug,
to retrieve the codeplug from the radio, as well as saving and retrieving the codeplug as a
file on a floppy or hard disk. The RSS allows the codeplug / personality to be stored on
disk, cloned, or edited without the radio as well. The HT1000 radio has an internal
microprocessor which runs its own program from embedded firmware. This radio
firmware reads the data / codeplug and uses this data to configure it’s receive/transmit
frequency, power modes, squelch controls, tone controls, etc.
Basic Requirements
1. Motorola RSS (Radio Service Software)
2. Old, very slow computer (around 100mhz seems to be optimal) with at least (1)
serial port running DOS.
3. Motorola RIB or RIBless cable
4. Motorola HT1000 with a fully charged battery or a battery eliminator
5. Ham Radio License authorizing you to operate on the frequencies you intend to
use.
Note: If you’re just programming MURS, or setting the programmed channels
to not transmit then obviously you won’t need a license
Computer Hardware
It’s important to understand that you do not want a newer, fast machine. You something
between 100mhz and perhaps 200mhz at the upper limit. You also should (to be safe)
only operate this system using MSDOS. I’ve tried MSDOS 7.10 and it works fine. An
older version works as well. The Motorola programming software was written in the
early 90s and although updates were made as recently as 1998 it’s safe to assume that
noting newer than that should be used.

Laptops vs. Desktops
I prefer to use a laptop with a good battery. I’ve had desktop systems die because the
UPS failed, commercial power failed and while the odds are certainly against it
happening while you just happen to be in the middle of writing a new codeplug into your
radio, it could happen. With a laptop I don’t have to worry about it. If you use a RIBless
connector and have secured it by screwing in the DB9 connector there is very little that
can interrupt your write operation. I also like using a laptop for when shtf and you may
not have commercial power but can keep a laptop charged. With the HT1000 since you
have only 16 channels, you may find yourself re-programming them often if you travel
outside of your normal area of operations.
Memory requirements are minimal. I’ve operated RSS in as little as 16mb of memory, so
I am sure whatever you have will do just fine.
Disk space requirements are also minimal. I have a Panasonic Toughbook with only a
4gb disk and to be honest that is about 3gb too much even with Windows 95 installed.
You should have at least a floppy drive in your machine so you can make backups of
your codeplugs and store them somewhere safe. It’s important to keep backups, you will
eventually need them if you do a lot of hacking on your radios.
Basic Procedure
1. Power up your computer, get into DOS. It is important that you are in DOS, not a
command window opened under Windows itself. You can either boot a DOS
floppy or restart Windows in DOS mode. For more discussion why this is
important please see Appendix A.
2. Make sure your HT1000 is turned off, then attach the RIBless cable to a serial
port (usually COM1) and then attach the cable to your HT1000. Power up the
radio at this time.
3
The RIBless connector should fit snugly, make sure it’s well secured.
3. Depending on where you installed the RSS you should change to that directory.
CD \MRSS\HT1000
HT1000
4. You should see the following “splash” screen.

5. Press “Enter” and proceed to the main menu.
6. Make a backup. If this is the first time you’ve programmed your HT1000 it’s a
very good idea to save it’s current configuration. You can do this by choosing
“F3” and then from the “Get-Save-Clone Menu” choose “F2” (Read Data from
Radio), then save the contents of it’s “codeplug” to disk by using “F7” (Save
Workspace Data to Archive File), the RSS will name the file based on the radio’s
serial number. It might be a very good idea to archive this within a zip file or
relocate it out of the RSS directory “ARC” which is the default location that RSS
uses to save/read codeplug data in order to preserve the “original” data.
7. Program the HT1000. Once you’ve made a backup copy of the codeplug, and you
wish to proceed to actually programming the radio, exit the “Get-Save-Clone”
menu by pressing “F10” and from the main menu, choose “F4” which is
“Change/View Radio Codeplug Data”. In the “Change/View Menu” you can re-
program every facet of your radio’s functionality. Once you’ve made the
necessary programming changes you should exit the “Change/View Menu” and
return to the “Get-Save-Clone” menu. Save the modified workspace data by
choosing “F7” (Save Workspace Data to Archive File) and using the <TAB> key,
select a new file name. Since you’re working in DOS, remember that the filename
can be 8 characters long with a 3 character file extension. An example of a valid
filename would be:
terminus.001
Once you’ve saved the modified data, you are
now ready to write the new configuration to the radio. It is critical that this
process not be interrupted so make sure your radio battery is not low, and that the
RIBless cable is securely attached. Once you’re ready to proceed, press “F8”
(Program Data Into Radio). You will see a Red warning screen pop up prompting
you with a last reminder of what you’re about to do, and offering the option to
cancel or proceed. Press “F8” again and you will see a progress window pop up
indicating how far along the process is, and you should hear a “beep” at the
beginning of the process and a “beep” at the end. There should be no error
messages. If there were you probably just destroyed your radio.
