Dear all,

Please recommend me some exciters for our radio station,
– analog exciter
– MPX input (for BBP )
– 30W

I know only R.V.R., so i’d like to know your opinion for alternative options.

Thanks.

Maybe unknowns brand, but good transmitter for less money: http://www.pcs-electronics.com/cybermax … -1404.html

Does that have a composite input on it that bypasses all of their audio processing?

If all I wanted was less than say… 300 watts, I would get one of these:

and then build my own amp for it. Saving the money for a decent antenna.

They do make something close to your needs though:

Great quality, not cheap. Just the exciter, and building your own amp, and you’re probably still talking about less than $250 USD total.

The new models come with optional ports for:
- USB port for RDS
- 3 BNC connectors for MPX in, MPX out and 19KHZ pilot
Info taken from their User Manual PDF.

I think this one is around 1500€, but you must call to check.

Sigmacom is interesting seem to be good.

For BW broadcast, it is 100 Khz step, i need 10 Khz step (.75 Mhz).

Thank you.

Most PCS have PLL steps adjustable to 5KHz-200KHz
If you can electronics, get this one and box it yourself, 40W for 399. http://www.pcs-electronics.com/maxpro-5 … -1845.html

No problem, go for one of there boxed and ready to use transmitters: http://www.pcs-electronics.com/transmit … c-1_5.html

PCS also have antennas and cables, all you need, and great service.

It depends on the performance you want.
The DDS FM technology is considered as a professional cutting edge solution.
Many ordinary exciters with VCO+PLL, can’t compete at the same time the noise and modulation performance of a DDS.
Also, none analog exciter can process digital audio directly. The "digital" PLL exciters with AES/EBU input, are actually using DAC internally – and then they do FM modulation.

That’s amazing! *drool*

But I have wondered.. how much does the bit depth affect in this type of application? There seems to be something like 14bit and 12bit DAC’s with enough MSPS.. I have thought about building a DDS FM-modulator myself

yeahhhh, many hardware engineers say that they CAN MAKE a DDS FM exciter but their spurious and harmonics are going to planet mars

They key is the software that uses the DDS exciter
Sigmacom just MADE IT WORK perfectly and 100 % stable under any conditions! i ve seen it and it is a value for money

Sigmacom , are u ok? i m comming to your city in a few days!
can you respond? i thought u where out of Greece!
