Hi Geoff,

I suppose the reason for this is that My LPFM station is a CHR Top 40 station, taking place of say ZM / Edge etc.. LFM is the only radio station in our area catering for this market. If I'm paying someone to produce these, I want it to work with my station format as priority and if its useful to you guys also, would love for you guys to broadcast it also.

Cheers,
Ethan

Just a thought about why don't you include other music eg original stuff
that gets sent to you by upcoming musicians composers etc.

Rivendell for Automation is going nicely. Been using it since July last
year. I guess the machine has been voluntarily rebooted cos I changed it
to a newer faster machine. The old machine was still running fine... I
just wanted faster.

I'm running Rivendell on Ubuntu Linux now... I prefer Ubuntu over Suse
linux. And still have 3 machines linked together for production and
playlist manipulation. And I run my Discos (on a 4th machine) using
Rivendell and have lots of the popular tracks that people want sitting
on the sound panel and just drop onto the playlist when required. It is
so good not having to worry about software licences on my machines. Just
make another copy and put on the next machine as required. The joys of
open source.

Bryan in Invercargill has my old Rivendell machine for a long term loan.
It is only being used occasionally by a few of his DJs. I think he is
stuck in a Windoze world running powergold and winamp. He has a young
kid that goes around there every week and break things... even his
powergold database... and I foolishly got it going again from an old
backup that only had half his music collection in the database.
Oh well.

Cheers
Geoff

Subject: [LPFM] Switching a LPFM to slightly Higher Power Output

Hi All,

 

I am building a LPFM for our local community in the North Waikato.

As you might understand with the area it has rolling hills and with some obstruction here and there to reduce the coverage area.

I did see or read somewhere about being able to get a licence to use more output power.

I have not been able to find it again.

Is anyone able to place a link to the information, or provide the information?

 

Regards

 

Kevin.

 

This looks kinda promising:

I use MLB4 free edition from burnill.co.uk which I've tweak over a year or
so but that one I just found above sounds very nice, not just louder than
MLB4. I like that the new software processors have MPX output on them. I'm
just downloading the broadcast ASIO version to try as I have ASIO drivers
for the terratec.

Hi guys,

Just giving some heads up on a few cards on Trade Me that came up in my
search results today, a couple of Antex LX-44's for Windows. There's a few
professional cards popping up now second hand. They are PCI.

http://www.trademe.co.nz/Browse/Listing.aspx?id=228932766
http://www.trademe.co.nz/Browse/Listing.aspx?id=228880964

I personally own an LX44 and vouch for how good a card they are. They're
only PCM cards (no fancy hardware MPEG decoding etc...) however they have
four balanced analogue outs (either 2 stereo or 4 mono, or 1 stereo and 2
mono... assignable) and four balanced analogue ins, with four virtual
'stereo' wave devices in Windows that can be mapped to any physical output
arrangement.

The noise floor on them is around -84dB @ 40Hz using unbalanced on the input
and not terminated (on mine anyway). Above 100Hz better than -96dB in cool
edit on a 16-bit 44,100 sample (the D/A's are 20-bit).

The LX44's do up to +24/26dBu which is why I have one for playback. I use
the SMPTE reference of -20dBFS for 0VU (@+4dBu) which gives me a further
20dB of room on my PC's for peaks over 0VU on true VU meters.

I also tested a Terratec Phase 22 (I've seen a couple for under $60 the last
fortnight) to see what those German cards are like. They have balanced TRS
in and outs and don't go above -96dB noise in my machine in 16-bit mode
until below 20Hz(ish). The drawback with the Terratec is that the input and
output is still not a professional level, they're +8/9dBu (2.2vrms) out with
reference to 0dBFS, but okay for software audio processing to a TX where 0
or +4dBu is the limit. The Terratecs have multiple crystals on-board aswell
including 22KHz so you get true 44,100Hz rec/playback not dithered 48Khz
playback like cards with 24KHz cyrstals. You can sync multiple cards in a PC
to one clock and their output is very clean and worth the buy if you're
looking for a entry semi-pro card. There's a few around now and then on
Trade Me.

Those are just my experiences with those cards. I thought seeing more LX44's
come up on Trade Me someone else might be interested.

Anyone else got anything to share about sound cards they use or tested?

Cheers,
Gavin.

This is an excellent example of "height is might". For anyone who doesn't
believe this, try getting your antenna significantly higher than where it is. It
will make a HUGE difference.
Then you will appreciate why most commercial FM transmitters are situated on the
tops of mountains.

Hey Peter,

cheers for the good words!

Well we have managed to relocate the transmitter via an intranet link. Our
signal should have been improved but still going through the testing stage of
tweaking the sound and transmission.

It seems to work fine over the intranet.

However I found a great solution for anyone else planning to do intranet
broadcast:

for using mono in the LPFM band.  You really need 300-400khz minimum gap for
stereo, but you can get away with a 200khz with mono on some receivers.

reception.  I'm basing my comments from experience with my car stereo.  When the
signal is week, there is no increase in noise, and there is a small but
noticeable reduction in treble, and stereo separation.  Perhaps it is just
switching completely to mono.  Only when the signal is very week does it go to
noise.

a matter of receiver performance and antenna quality. Most cheap receivers are
built for environments where they have high powered transmitters close by making
reception a non issue and the dollars saved in production means lower prices.

amplifier stage the signal is limited or chopped off to remove any AM component.
If the signal is not strong enough to reach this limiting point you get noise. I
have a couple of researchers where I work who spent hours trying to get rid of
background noise on their Lab receiver. They spent hours going around the
buildings trying to trace the source of the noise while I smiled - all because
they would not take my advice and install a decent antenna.

or switches the receiver to mono to reduce noise. At home I have an old JVC
receiver with a car gutter mount whip aerial so if I try to listen in stereo I
find I have about 1 reasonable station but switching to mono I can pick up 10 or
so. I haven't paid the price for good equipment so I don't blame the stations I
just get what I paid for.

I went past a motor vehicle dealer yesterday and spotted a freshly sign
written motor Vehicle with Hauraki on the bonnet and a frequency 106.2
on the side... that will be the new TRN fm station in Dunedin. (I took
photo with my camera phone too)

Subject: Re: [LPFM] Suggest a good transmitter

Hi guys,

thanks for all this info.

The reason I am asking is that we currently have a mono TX and should be in the most ideal place for maximum distance being on a very high hill that overlooks Wellington city, however for some reason we have very bad reception everywhere.

We are currently in the process of switching our TX location on top of the highest building about 100 meters away.

So we are forced to send a stream over the intranet from 1 linux box in our studio to another that is in the plant room of the 10 storey building where the TX will be relocated.

To give you a bit of background: When we first started we had no idea how LPFM worked etc. Our studio being located in the basement we had to run a 30 meter RCA cable up to the 5th floor which connected to the TX and then COAX to the Aerial that was about 18 meters away.

Now with the relocation we will be sending a 320 Kbps stream and the stream will connect to the TX and 15 - 20 meter Coax that will connect the aerial.

I am sure this should improve the quality of the transmission... I do have a few questions though.

1. If we are sending an audio feed from our compressor through the intranet, will it need to be compressed again when it comes to the TX location computer.

2. what would be the best way to compress and send a stream of audio via linux ubuntu computer? icecast or anything better?

3. Do I need to upgrade the soundcards to be ballanced or something?

I am a newbie when it comes to all this radio knowledge but I cannot seem to find solutions via the net.

cheers,

Doug

Most cheap receivers are built for environments where they have high powered transmitters close by making reception a non issue and the dollars saved in production means lower prices.

> The reason FM radio is quieter is because in your receiver IF amplifier stage the signal is limited or chopped off to remove any AM component. If the signal is not strong enough to reach this limiting point you get noise. I have a couple of researchers where I work who spent hours trying to get rid of background noise on their Lab receiver. They spent hours going around the buildings trying to trace the source of the noise while I smiled - all because they would not take my advice and install a decent antenna.
>
> Most receivers have a muting stage which mutes out weak stereo signals or switches the receiver to mono to reduce noise. At home I have an old JVC receiver with a car gutter mount whip aerial so if I try to listen in stereo I find I have about 1 reasonable station but switching to mono I can pick up 10 or so. I haven't paid the price for good equipment so I don't blame the stations I just get what I paid for.

Hi Matrix,

we currently broadcast on 88.3FM in Wellington and have been doing so for the
past 3 years.

I should have given myself a better introduction.

cheers,

reception.  I'm basing my comments from experience with my car stereo.  When the
signal is week, there is no increase in noise, and there is a small but
noticeable reduction in treble, and stereo separation.  Perhaps it is just
switching completely to mono.  Only when the signal is very week does it go to
noise.

matter of receiver performance and antenna quality. Most cheap receivers are
built for environments where they have high powered transmitters close by making
reception a non issue and the dollars saved in production means lower prices.

This was even the case in good old AM days as well.

stage the signal is limited or chopped off to remove any AM component. If the
signal is not strong enough to reach this limiting point you get noise. I have a
couple of researchers where I work who spent hours trying to get rid of
background noise on their Lab receiver. They spent hours going around the
buildings trying to trace the source of the noise while I smiled - all because
they would not take my advice and install a decent antenna.

or switches the receiver to mono to reduce noise. At home I have an old JVC
receiver with a car gutter mount whip aerial so if I try to listen in stereo I
find I have about 1 reasonable station but switching to mono I can pick up 10 or
so. I haven't paid the price for good equipment so I don't blame the stations I
just get what I paid for.

Hi Doug
Is an internet link the only way to do it?
I've heard of 2 ways you might want to consider instead of streaming.
(Most streaming solutions add a delay to your signal 2 - 120 seconds
depending on your system.) (I use Darkice, shoutcast and Debian linux
for my internet streams and have 20 - 90 seconds delay.)
1. Use a video sender from Dick Smith or Jaycar? It is possible to
extend the range with directional aerials. This needs line of site.
2. Run a balanced 50 volt line from studio to TX. Line transformers cost
$10 each. You run your TX out into an Audio Amp. The speaker out goes
into one transformer... the voltages gets stepped up to 50 volts... goes
over a length of cable and gets stepped down to normal line level at the tx.

- Both of these solutions require your audio processing at the studio
end only. If you wanted to be stereo I think you need to double up your
lines, because I don't think transformers are capable of running the
19khz pilot tone through it.

Hi guys,

thanks for all this info.


The reason I am asking is that we currently have a mono TX and should be in the
most ideal place for maximum distance being on a very high hill that overlooks
Wellington city, however for some reason we have very bad reception everywhere.

We are currently in the process of switching our TX location on top of the
highest building about 100 meters away.

So we are forced to send a stream over the intranet from 1 linux box in our
studio to another that is in the plant room of the 10 storey building where the
TX will be relocated.

To give you a bit of background: When we first started we had no idea how LPFM
worked etc. Our studio being located in the basement we had to run a 30 meter
RCA cable up to the 5th floor which connected to the TX and then COAX to the
Aerial that was about 18 meters away.

Now with the relocation we will be sending a 320 Kbps stream and the stream will
connect to the TX and 15 - 20 meter Coax that will connect the aerial.

I am sure this should improve the quality of the transmission... I do have a few
questions though.

1. If we are sending an audio feed from our compressor through the intranet,
will it need to be compressed again when it comes to the TX location computer.

2. what would be the best way to compress and send a stream of audio via linux
ubuntu computer? icecast or anything better?

3. Do I need to upgrade the soundcards to be ballanced or something?

I am a newbie when it comes to all this radio knowledge but I cannot seem to
find solutions via the net.

cheers,

Doug

using mono in the LPFM band.  You really need 300-400khz minimum gap for stereo,
but you can get away with a 200khz with mono on some receivers.

Item 4 is much more important when using stereo.  Another good reason for using mono in the LPFM band.  You really need 300-400khz minimum gap for stereo, but you can get away with a 200khz with mono on some receivers.

From an old-timer

I have always believed that FM reception ( irrespective of if you are Mono or Stereo ),

depends largely on the following:

1: your transmission setup , ie antenna and transmitter.

2: your location

3: the quality of your transmitter input signal ( this does affect the RF outout results ).

4: the proximety to other stations on similar frequencies.

many other factors are also involved, but as we see it here in the Hawke Bay, co-operation

between stations tends to be the most important for all involved.

tahts my 2 cents ( now obsolete ) worth.

You are basically confirming exactly what I said, except the car radio reception.  I’m basing my comments from experience with my car stereo.  When the signal is week, there is no increase in noise, and there is a small but noticeable reduction in treble, and stereo separation.  Perhaps it is just switching completely to mono.  Only when the signal is very week does it go to noise.

In comparison, I’ve been in another car where it doesn’t reduce the treble when the signal is week, but you get much more noise instead while driving around.

Hi all,
Sometimes I get amused reading the comments on this group mainly because not many have a technical background.
When it comes to mono versus stereo transmission it is just about 100% a matter of receiver performance and antenna quality. Most cheap receivers are built for environments where they have high powered transmitters close by making reception a non issue and the dollars saved in production means lower prices.
As far back as I can remember good stereo receivers listed the sensitivity for mono and stereo showing they needed a signal 3-4 times stronger for stereo. Most people who pay top dollar will not skimp on a good aerial system.
As far as car receivers – they always have a good RF amplifier stage and a properly matched antenna because moving around is quite a demanding situation. This was even the case in good old AM days as well.
The reason FM radio is quieter is because in your receiver IF amplifier stage the signal is limited or chopped off to remove any AM component. If the signal is not strong enough to reach this limiting point you get noise. I have a couple of researchers where I work who spent hours trying to get rid of background noise on their Lab receiver. They spent hours going around the buildings trying to trace the source of the noise while I smiled – all because they would not take my advice and install a decent antenna.

Most receivers have a muting stage which mutes out weak stereo signals or switches the receiver to mono to reduce noise. At home I have an old JVC receiver with a car gutter mount whip aerial so if I try to listen in stereo I find I have about 1 reasonable station but switching to mono I can pick up 10 or so. I haven't paid the price for good equipment so I don't blame the stations I just get what I paid for.
How about spending time on your stations to educate your listeners – a little technical knowledge can be a big benefit and maybe gain a listener for life.
