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

Station Control info

Station Control Module or SCM is the heart of the Quantar station. The SCM comes in different revisons known as EPIC.

• EPIC I - TTN4094
• EPIC II
• EPIC III
• EPIC IV - This is only for the Smart Zone trunking. IT will not work for conventional
• EPIC V

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. 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).

80 Pin SIMM Programmer

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.

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. 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.

Troof Table

There is a ID code representing the exciter type, it consists of R3700 to R3710. These are either pull up or down resistors on a 6 bit code and are identified on the schematic on the left side of U3700, the μP. Below is the table in MSB-LSB format, with a 1 being high (5v) and a 0 being a low (0v).

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.

PCB Layout High Power

PCB Layout Low Power

[[|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

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.

UHF R0 to R2

This is doable

UHF R1 to R2

Converting the R1 (403-433) to R2 (438-470)

I've done a number of these that all meet spec. If your planing on a conversion it's the best to start with, due to PA isolator covering it, and it being easier to remove material from the preselector than add it.

I've never done a R3 or R4 to R2, I'd like to though.

the R0 is easy as well, but it's got a different design to the VCO's.
