Isn't 1 watt twice what you are allowed under the rules of LPFM here in NZ?? I'm just checking because I'm about to buy a TX too and 1 watt would be...
... As I understand it, the 500mW is "radiated power" measured a certain distance from the antenna, not transmitter power, so it depends on what your antenna...
Yes, but when you take into account loss due to SWR (which are affected by a number of factors), loss through co-ax cable, the fat pigeon that roosts on your...
Could people out there that have the Veronica brand of transmitter, please message me. I have a few queries for you. Cheers ... Do you Yahoo!? Meet the all-new...
Do I? OK, here's how it works. First the golden rule: Everything in FM works backwards. Why? Receive level dictaes radiated power which dictates antenna gain...
Er Jochen, Since when has a dipole antenna had 3db gain? I am assuming a 1/2 wave ant. Cheers Brian ... Do I? OK, here's how it works. First the golden rule:...
... I'm fairly sure a standard dipole was considered the base unit for measuring antenna gain, and it was given a 0db gain rating. ie. All other antennas gain...
Isn't the base unit on which antenna gains are measured is an isotropic radiator? A dipole does not radiate in an isotropic fashion but instead a flattened...
I blame my poor memory :-) I've checked with the experts, a standard dipole has a nominal gain of 2.2dBi. But the principles are the same. I always forget the...
You can use dBi (gain over isotropic) or dBd (gain over a dipole) A dipole has 2.2 dBi, or 0dBd Remember the basics: To quote something in dB is only correct...

Please disregard my previous message dah! I had a visit from your average freindly R.I just last week and he questioned my use of 1 watt. I protested my...

Trust the visit showed you complied with all applicable rules and regulations :-) He insisted correctly - a folded dipole = 2.2dBi gain. See my previous posts...
Hi M.B., The only policy framework in place is for non-commercial community TV. This gives you a free licence, subject to your complying with certain ...
I just sold my radio broadcasting software to a non-commercial TV station in Pakistan. They spent $500 on my software, a couple of hundred on a PC video card...

Okay, so we've thrashed the Veronica brand of transmitters here quite a bit. But what do you think of NRG vs Broadcast Warehouse? I'd be interested in any...
I am using a NRG and have found it to be very good in an operational sense. As far as building it and mounting it, it ain't so grand. The actual assembly is...

That's interesting. I wonder why a more common 96khz soundcard could not be used. I believe the modulation never exceeds 75khz for FM. Ross. ... From:...
It looks like it's all got to do with the maximum frequency of the sound card before the 15KHz filter is applied, I don't fully understand it myself as it...

Hi - here is why you would need a wideband soundcard for a software modulator "Stereo audio signals are also transmitted by the FM station using a form of...

The 19Khz is the pilot tone – the sub-carrier is 38Khz so the stereo info is modulated round 38Khz meaning its bandwidth is 23Khz-53Khz. Stewart Finlay ... ...
