FM band exciter with incredible features, now new hot v2.1

The new MAX PRO 3000+ FM exciter is a complete redesign of our old and extremely popular MAX PRO 3+ board covering entire FM band from 87.5 to 108MHz (extendable for japanese band down to 76MHz) without any tuning. We have taken the best of the old and added an impressive number of new hot features such as power/swr readout, temperature readout, modulation level readout, complete supervising of optional output amplifier with power, swr, voltage and current readout and remote control via RS232/USB. Units also feature easy connect Maxlink socket, DIGIAMP socket, improved silent cooling system and the new ALC (Automatic Level Control) system. SWR and TEMP alarms can be adjusted via LCD and protect the unit from destruction. See the manual for a full list and explanation of all the features, a number of usefull guides are included as well!

The design of the MAX PRO 3000+ is the result of over 2,000 hours of research and development, encompassing mathematical analysis, computer simulation and modeling, and numerous prototypes and experiments spanning over several years. The result is a rugged, high quality FM exciter designed to run silently and cool 24/7. The MAX PRO 3000+ is purposely over-engineered, using the very best components and materials that can be located. MAX PRO 3000+ is built the way you would build it for yourself if you had the time, knowledge, money, and inclination to do so. Why wait? Your dream FM exciter is a reality right now!

The exciter carries a one year limited warranty on parts and labor against defects in materials and workmanship, except the RF final transistor.

You can find the manual for this (and other products) here.

How is MAXPRO3000+ v2.1 better than previous versions of MAX PRO 3000+?
- Better output stage efficiency and as a result slightly higher maximum output power
- MAXPRO3000+ v2.1 now has complete PC remote control (USB/RS232).
- MAXPRO3000+ v2.1 features ALC (Automatic Level Control); keeps output power level the same across the band
- MAXPRO3000+ v2.1 shows an additional parameter, that is Amplifier Current. Requires external filter PCSLPF 5000+.
- MAXPRO3000+ v2.1 has improved firmware
- MAXPRO3000+ v2.1 now allows LCD module in DIP mode; LCD module shows frequency that is set via DIP switches
- MAXPRO3000+ v2.1 has a number of small improvements
- MAXPRO3000+ v2.1 has greatly expanded new manual

Technical specifications:
- RF Output Power: 0 to 15 Watts (22W max., 14-18W typ, fully variable via LCD or trimmer)
- Some units do up to 25W, but pushing them above 15W is your responsibility (may reduce life)
- Output connector: BNC
- Output Impedance: 50 Ohms
- Frequency range: 87.5-108MHz (76-108 via DIP switches, reduced output)
- Extended frequency range: 40-54MHz (*)
- PLL Steps: 5KHz (10/25/50/100/200KHz adjustable via lcd)
- Frequency stability: +/- 20Hz
- Spurious/Harmonic rejection: Harmonics: >50dB, Spurious: -90dB
- Power Supply: 11-15V/2.5A or car battery (does not require 15V anymore)
- Power connector: 2.1mm power socket, center (+)
- Quartz Locked PLL Frequency Control

- PC Board Size: Same as MAX PRO 3+, 100x125mm
- Audio connectors: RCA jack, optional MCX

(*) In extended frequency band PLL/VCO support 40-54MHz without modifications, but output stage requires modifications to reach full output power and required filtering.

What parameters can I change via remote control?
Its best that you look at the screen capture below. The program may change slightly over time as we make enhancements, but the main features will remain as below:

Can I upgrade my CyberMaxFM+ transmitter with new exciter?
Sure, but note that some old units had different I2C connectors to the stereo encoder. If your stereo encoder is not the new SE5000 you may have some trouble figuring out the connections so it may be better to replace the stereo encoder as well (replace with SE3000 or SE5000 with new MaxLInk I2C socket)

What is the IO board and why do I need it?
IO board is required, if you want to control MAXPRO3000+ remotely via RS232. It plugs into the LCD control module.

What is the ControlMini1 board and why do I need it?
ControlMini1 board is only used when you install this exciter in an enclosure together with amplifier. It can than be connected to mains power supply to control the voltage and with that the output power. It plugs into the MAXPRO3000+ via flat cable. You can read more about this in the manual.

What is the ControlMini2 board and why do I need it?
ControlMini2 board is only used when you install this exciter in an enclosure together with amplifier. It can than be connected between the exit from filter and antenna connector to provide power, swr, temperature and voltage information to the FM exciter. It plugs into the MAXPRO3000+ via flat cable. You can read more about this in the manual.

What is the Software+IOBOARD for changing logo?
This is a combination of special unlocked version of software and RS232 IO board, which is required to control MAXPRO3000+ remotely via PC/RS232. It plugs into the LCD control module. Software lets you change welcome text (logo); you can replace that text with your company name for example. Your customized text will be saved and used at every power-up.
