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

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

Oh yeah duh… how could I forget about this one. This is the last exciter you’ll ever need. 8)

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

I didn’t have knowledge about electronics, unfortunately 😐

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!
D U still speak Greek ? 🙂

p.s.
( i ve 150 mbps 18 km wi-fi link at -54 working with uptime 3 monhts, IT IS TIME FOR your FINAL DDS version 🙂
( also , 60 mbps 49 km wi-fi link with the second transmiter site stable 🙂
