Quantar/Quantro info
There is a bunch of info here about the technical aspects of the Quantar Stations.
The info on the modification and changing ranges of the various modules is on the respective pages. There is some conversion info below, but it's being migrated and reformatted under the respective pages. I feel this is more logical.
If you find anything to be wrong here, please feel free to make an account and change it. I've had to lock down account creation, so you'll need to have it approved. If you want to email me directly, my email is bryan@bryanfields.net

Firmware
The newer SCM modules can be upgraded via SLIP connection over the tty port, or via IP over the 10Base2 connector (anyone have a hub?).
The Wireline typically will upgrade during this too, unless it has the older EPROM memory. At that point you'll have to swap the chips.
The exciter is still a hard chip swap upgrade, but programed EPROM's are $20 shipped on eBay. Unless you have more than a few to upgrade it's not cost effective to buy the programer and chips yourself.
SIMM Images
The SIMM has a boot1 image which is a basic bootloader (0x460-0x3ffff). This runs just after the bootstrap code (0x000 0x45f). The bootloader (boot.o) contains basic code to initialize the hardware and validate the boot2.o, sc.o and wl.o images stored in the SIMM. It also has a slip loader in it. With only the boot.o code running it's possible to reload the entire OS at 9600 baud via the front port.
The boot.o is the only code not able to be upgraded on the SIMM via SLIP/FTP. To upgrade boot.o you need to flash the SIMM directly. Normally boot.o does not matter, but it is different for IR and NIR stations. The other issue is the newer (EPIC III) SCM cards will not boot with boot.o 020.10.001, and need at least the 020.10.008 code. The newest boot code is 020.10.012, and the images below have that code on them.

The only difference between the various versions of the EPICs (excluding EPIC IV) is the hardware is newer. There is no difference in functionality for conventional analog/astro/P25 operation.
SIMM info
The SIMM used for firmware in the Quantar EPIC 2/3 is an 80 pin SIMM and is basically unobtanimum. It is possiable to use a Motorola Console Operator Interface Module SIMM if you want to modify it.
The conventional uses 4, 29F040 chips arranged to be 32 bits wide. This means each chip stores every 4th byte.
Example we store "QUANTAR MOTOROLA" in the SIMM
| Chip 1 | Chip 2 | Chip 3 | Chip 4 |
|---|---|---|---|
| Q | U | A | N |
| T | A | R | |
| M | O | T | O |
| R | O | L | A |
So if we read Chip 1 we'd see QTMR.
The IR uses a two bank SIMM with the same layout (8 chips total)
It's possible to pull these chips and read/write them if you have the right programmer. Taking advantage of this I was able to build a SIMM programmer for the soldered in place SIMM's that essentially programs one chip at a time (8bits).
It's not pretty but it works.
The SIMM has the ability to be upgraded via the SCM download procedure, but the IR SIMM and NON-IR SIMMs cannot be interchanged. This is do to the boot code being different. Using the SIMM programmer or the socketed SIMM you can reprogram the SIMM's for either.
SIMM-less SCM
It is possible to use 29F040 chips in the sockets on the EPIC 1 with just a flick of the Flash switch, this makes it easy to use the current Quantar Firmware in the EPIC 1 with just standard DIP chips.
In the later revision EPIC's the DIP sockets are only used for 27c040 chips which have a slightly different pinout. It's possible to use the SIMM images as u1-4 maps to U451-454 with a slight modification to the chips. Typically I'll bend up pins 1, (A18 on Flash, VPP on EEPROM) and 31 (!WE on Flash, A18 on EEPROM), and then connect a wire from the board at pin 31 to pin 1 on the chip. A connection to !WE on the chip is optional unless you want to be able to upgrade the chips. In this case you'll need to make a conection from SIMM pins 53, 29, 6, & 5 to the !WE lines on U451-U454 respectively.
The Quantar doesn't care about the ID pins on the SIMM, but I typically will tie 74, 75, 76, 79 to ground/pin 80. If you're doing an ATAC 3k, the ATAC does care about this and you need pins 76 and 79 tied to ground.
Of course the Intelerepeater and ATAC9k will not work in this configuration as they need two banks on the SIMM, so you can't do this if that's your requirement. For most ham stuff, there's no reason you need anything more than NIR code for Quantar and ATAC 3000.
Receiver
Like the rest of the unit the receivers are frequency dependent and consist of their own modules. The basic receiver has a preselector which is 4 MHz wide on VHF and 6 MHz wide on UHF.
The receiver is an excellent high side injection design (exception for 800/900 which is low side). The first IF is +21.45 MHz on VHF and +73.35 MHZ on UHF/800/900. The second IF is 455 KHz. In many cases barefoot (minus preselector) the receiver sensitivity is under .112μV (-126 dBm) for 12 dB SINAD. Couple this with the great built in selectivity and it's truly a bullet proof design idea for high RF sites.
The receiver is pretty dumb, there is not a μP on the board, making it easier to troubleshoot. The devices receive their programming from the main CPU on the SCM via SPI bus. The two main chips are the U2500 receiver IC and U2401 PLL IC. U2401, the PLL, is a custom chip responsible for locking the VCOs to the proper frequency, and selecting the high or low VCO. U2500, the receiver IC, contains the 2nd IF/VCO and final processing of the intended signal. Unlike other designs, the receiver IC presents the recovered audio/data as two digital signals to the SCM where A/D conversion happens (if needed).
There are a couple other chips which present various
UHF R0 was added later and extends the coverage and tuning range of the unit down to 380 MHz. The preselctor for this covers the whole range as well.
Each item has more information on it's own page and covers conversions there as well.

Exciter
The exciters contain their own CPU which communicates with the SCM over a SPI bus. This CPU runs it's own firmware and requires a socketed UV EPROM to upgrade it. This also controls the PA meeting and the bit of EEPROM in the CPU stores the alignment settings for the exciter and PA. Generally a Exciter/PA pair will not need to be realigned if moved from one chassis to another, although it should be checked.

Power Amp
The power amps are actually a cool design.
Their are two basic power amps, a 25W, and a 100/110/125w (depending on band). The power amps all use the same general board layout, with the frequency dependent parts separate from the support components. The 25W PA is a passively cooled unit with a massive heatsink, while the 100/110/125W unit has active cooling with a horizontal heatsink and two cooling fans moving air front to back.
There are a couple different revisions of the PA's so the main PCB has changed a bit over time.
[[|thumbnail|center]]
The PA doesn't contain any CPU, it's controlled via the exciter CPU with basic analog level lines going over to the exciter. Some of what's measured by the exciter
- Intermediate PA drive level - this is the output of the IPA to the final PA pallet
- Driver PA Level - output of the final PA before the circulator (FPA_DETECT).
- TX Power Forward - Output measured at the output of the Low Pass Filter
- TX Power Reverse - Reflected Power from the antenna port
- OMNI voltage - this is the control voltage on the IPA which comes from the SCM as a 0-5V control signal (V_CONT). This 0-5v controls a transistor making a 0-14v signal to provide the gain of the IPA. This is the basis of the power control. The Control Voltage from the SCM is only present during keydown.
- IPA Current detect
- DPA Side A & B current sense
- Temperature of the PA
- Fan on/off and alarm
- PA_ID bits A & B - resistor divider that programs to reference voltages in .5v increments to ID the PA hardware to the exciter.
All these are measured over an TDM bus that selects each at a 200ms interval using a single analog input on the exciter CPU.

Conversions
Work in progress on moving Qunatar bands. These are depreciated, refer to the pages on each FRU.
Going to move this to the various exciter/PA/receiver pages verses having its own page.
VHF R2 to R1
Looks like it should work
Exciter
Parts difference and re-tune the VCO's
Amplifier
25W PA
This covers both R1 and R2.
125W PA MODELS TLD3101/TLD3102
The 125W PA is the same PA pallet, Low Pass Filter, and IPA. The circulator is different, and about 300 from MOTO. Should be a matter of changing the ID bits
CLD1298 and CLD1299 newer 125W PA's look like they are them same.
VHF R2 to 220 MHz
Software works, it's putting the R4 code plug in, verified the 212.5 cross over frequency for the VCO's. Still need to work out some bugs in it. Should use the 800 MHz for the 220 MHz programing.
Exciter is working.
PA is a complete rebuild, working on it, circulator is being reworked. The A+B voltage feeds are a problem. Right now it keys up, and then shits the bed as the PA is fail. I've tested it by putting good voltage on the IPA, PA, FPA and SWR sense lines. Still doesn't like the PA not drawing current and craps out after like 30 seconds, but it was long enough to test the output from the exciter, it's 13.5 dBm on the Rigol.
Receiver VCO is working, need to modify the image filter and test.
