Hi.
Have anyone make-cp.exe for R100 ?.

I believe that R100 is a suitcase Programmer

The R-1801 is a suitcase programmer. ?
The R-100 is a small Motorola repeater built from 2 modified mobiles. ? See:?
I believe the OP is looking for a piece of software that can program a new EEPROM to replace a bad one. ?(A piece of software that I wish I had)
Hope that helps,
Will

I had a couple of R-100 repeaters and they appear to have specific designed tx and rx boards and not from any mobile I've seen. The repeater is also programmed by software and not EEPROMS, I have the software somewhere and maybe even a programming cable but its been a good 30yrs since I've worked on one.?
|
To add, the R-100 programming software runs on DOS and does not use the old RIB interface, its a simple to make serial type cable.?
|
And my final comment, the R-100 repeater was not very reliable and was plagued with power supply problems. Of the two I had here both had failed power supplies when I put them in storage and when I retrieved them many years later neither would transmit or receive. Both went in the trash can.?
|
My R-100 experience wasn't a good one either, a local ham brought me one that blew a fuse while operating in his garage.
I found a fuse blown figured it was the electrolytics that failed so ordered new ones and installed them.
After more smoke, I discovered the bridge rectifier was shorted.? A LOW duty design for sure!

Actually, I've veen running an R100 repeater as an Allstar node continuously for over 15 years...of course, it's turned down to less than 1w and I disabled the internal PS a decade ago. Also, it's a good job I haven't needed to reprogram it in all that time because I expect I'd be SOL. If someone ever finds that standalone program to make codeplugs, I'd be interested, too...

Hi.
I have examined the radio and it appears that the original (codeplug) eeprom has reached the end of its life and needs to be replaced with a 24C01 or 24C02 serial eeprom chip.
WA1MIK has made a program that can write eeprom data to the M100 radio but apparently the program is not publicly available anywhere?.

|
Sadly, WA1MIK is a silent key so I doubt the “make-cp” program is available. ? The data in the eeproms on the R100 is very, very susceptible to being corrupted if using too fast of a DOS computer and 30 years ago if you hosed one up the only way to get the station back on the air was to purchase a blank (preformatted) eeprom from Motorola in order to reprogram the radio.? The R100 requires (1) eeprom for transmit data and (1) eeprom for receive data and each eeprom must be initialize with a unique data string that is different depending on if the radio is a PL or DPL model.? I am assuming that is what the make-cp program does. ? Somewhere in my archives I made a copy of the “blank” eeproms that I had to order from Motorola for a customer many years ago but doubt I could find them now. ? Andy / NC4AB ? ? ?

The boards are from the German made MC Micro series. ?
They are, in fact, mobile radios repurposed to be a repeater, whether you’ve seen one, or not. ?
I hope that helps,

Pinari,
?
I'm going back decades here, but this is what I remember:
?
As others have pointed out, the R100 repeater is based on European mobiles that have much in common with (but are not identical to) the Motorola Maxtrac line.? Hardware is different for analog PL and digital PL, so check what you've got carefully.? As I recall they can be converted back and forth if you are strong technically.? Melted down PAs are fairly common on these, but as I recall, the PA from a UHF Maxtrac mobile fits just fine.
?
They are programmed with a DOS program and a special cable, not the normal RIB.? Early versions of the programming software had to read a valid EEPROM before allowing reprogramming, but later software versions could start with a blank or corrupt EEPROM.? The software also has to be hacked to allow 440 ham band frequencies, but I've probably still got it around here - likely on a 3.5 inch floppy disk.? I'll see if I can find it and the schematic for the cable.? If I have it, I'll send you a PM.
?
Good luck here - Kurt

Attached is a document I put together many years ago, which outlines how I successfully replaced R100 EEproms, back in the day.? I built a EProm programmer called "Pony Prog", I found described on the internet at that time.? Pony Prog? would program? the? ATMEL 24C02's.?? The programmer may still be documented somewhere on the internet.?? I haven't looked for it lately.? As I remember it wasn't terribly hard to build.
?
I'm pretty sure I can find image files for the? "blank" TX & RX? EEproms,? if it would help.
?
Don't know whether? the ATMEL 24C02's are still available??
?
Memory is fuzzy, but, I think in some cases I could read the R100 and then swap out the EEProms for the new EEProms with the "blank" image burned and write the image back out with the Motorola RSS.???? In other cases I re-programmed the R100 from scratch as described in the document.

They had the misfortune of new mot software that was made for 10 yo 8080, 286 or whatever with an old IBM keyboard so you had to know what the new keyboard keystrokes were that could march you through the software.? Had to be DOS on a 486 or older in low memory with a BIOS switch to make the processor slow.? Haven't done it since the 90s so dont know where the cable went...? Schematic is on Batboard.
?
Rebuilt a lot of PAs on them.? Like Maxtrac with a goofy heat sink glued on with a pound of Wakefield.? The Hi power brick would eat the driver, so best to go with the medium power ones and try not to rag-chew it to death.
?
Good luck with the chips.

In my opinion if you have an old Motorola R-100 repeater there are much better choices these days. Do yourself a favor and move on. Putting just an hour of labor into figuring out how to program or repair one will easily exceed their value.?
|
Late with this one,
If the R100 s/w is like the Motorola Comapct the Euro version then there's an option create a e prom form scratch? look for a "select device" menu?
I've still got business radio users running these and the work well for that,?
For Ham use the 10W version will run 10-15W all daythe 25 W ones wont do "ham" lenthg overs unless you fit a lot of fans and do the PSU mod
Swap the linear PSU for a Good SMPS and the box runs much cooler,if you want to keep the linear psu swap the 100uf caps at least if not all!
On the TRC (Control) bd check the 100uF cap's its likely they will have leaked and that causes all sought of issues? probably worth swapping all the caps, never had issues with the caps on the radio chassis.
The sticky pad that holds the crystal on the radio processor board eats the leads out of the crystal if the can's rusty remove the pad and re fix, if your lucky the crystal will be Ok
Easy to to add a controller or your chose? there's a Compact manual in the RB files section that has a few added notes .
?
Both R100 and the Compact? s/w will run on Win10 using dos box and a USB serial lead (FTDI)

Pienari,

All,
For what it's worth, I have located the diskette I made 30 odd years ago containing the R100 stuff.? This is the version that can create a code plug from scratch which I hacked to cover the 440 ham band, and I also have images for valid code plugs as well.? If anyone else needs it, send me a private email.? Remember that this software will only run properly on an old, slow native DOS computer, that it is very non-intuitive, and that it needs a special RS-232 cable that fits nothing else.? A quick internet search found the cable schematic at repeater builder.
Per my notes, changing an R100 from DPL to tone PL (or vice versa) requires both microcomputers to be replaced, as well as some other stuff, so I hope your R100 is the version you want.
My notes also noted that the original Microchip EEPROM was obsolete 30 years ago, but that an Atmel 24C01 works fine.

I found a file on my server that's labeled R100 EEPROMS that have a tx.bin and rx.bin file in it. I'm guessing it might be blank codeplugs for making eeproms? I don't know if anyone is interested in it. I've got 1 known working R100 and 3 parts units with various pieces missing that I've been needing to work on. I built the programming cable which was easy enough and have it running on my 486 machine quite well. Never can get the motivation to finish them.
