I'm forwarding to the President of ARC to make the necessary corrections in
that database.

John,

When you talk to them, ask them to update their web site with the NFCC.

I figured as much. Just thought someone may have come up with a way to
tap into the circuit and make it happen.

[kc7gf]

The Motorola R100 is another good choice for a portable UHF repeater, comes in a 15 and 25 watt version, is programmable, can be run directly off of 12v and is quite small.

You may find that even 7 bit audio is fine, if the samples are regular enough.

They get nasty when lightly loaded. A 2.2k pullup solves it.

John,

Contact Howard Grant (below) for coordination request.

The troy state univeristy url is old. Used to auto-direct you to the new
one, but looks like they've finally pulled the plug. The new one is:
http://www.alabamarepeatercouncil.org/ which Jim correctly gave you.

The website has an online application you can download and send to Howard.
I'd drop Howard an email telling him where the proposed repeater would be
located. You'll find many areas of Alabama have no open 2 meter pairs
available.

My recommendation: TLV2372 (dual) or TLV2374 (quad).  Rail-to-rail in & out 
& no crossover distortion.  There is a slight offset voltage shift about 
1.35 V below Vcc (not the same or as bad as crossover distortion but can 
affect the common mode rejection ratio); for maximum performance just run 
off of 12 V & bias @ 5 V for 0 to 10 V operation.

The LMC6482 & LMC6484 are allegedly better but pricier too.

Use a timer to space out the ADC samples.
The timer runs as long as the longest ADC conversion (BTW you can 
violate the aDC clock, you just get less resolution)
You don't start a new sample till the timer runs out.

Stay away from the LM324, nasty crossover distortion.

Re: [Repeater-Builder] Re: Delay line chip (DAD4096) for Kendecom Mark 4

[DCFluX]

Progress Report on this dead thread:

I got some free time to experiment.  I was able to make a attempt
using a ATtiny26.  I used the atmel's internal ADC biased to 2.5V with
100K resistors to +5 and GND and audio coupled in with a 0.22uF
capacitor.  For the DAC I used a resistor ladder built with 20K and
10K resistors and audio coupled out with a 0.22uF. And I am using a
256Kbit 25MHz bus speed serial nvram for the storage.

It works, But...

Because of the succesive aproximation nature of the atmel's ADC there
is not enough speed to make the project usable.  Each conversion takes
between 16uS and 256uS. and a different variable means a different
sampling time.  I was able to sustain a sampling rate of about 2.8kHz,
 which if you know anything about digital audio means that the best
frequency that can be passed is 1.4kHz.  I am doing some math to
convert the 10bit ADC to 8bit for the DAC and to save space in the
RAM, but it is not what is slowing it down as it is a simple Shift
statement.

So, It sounds like ass.  But you can hear audio running and I was
supprised by the fact that it actually worked at all.  It kinda sounds
like a really bad digital cell phone connection at the moment, or the
sound from a OP-amp that doesn't have negitave voltage to it.  The
closer I could get the audio to do a full swing from 0 to +5 or 5V
peak to peak the better it sounded because of utilization of more
bits.

I am now trying to locate 12 or 16 bit ADC/DACs to continue
experimentation, with sampling rates of either 32kHz for 12 and 44.1
or 48kHz for 16bit.

In the future I will use a dual op-amp for the audio in and out as it
will do a better job of biasing to 2.5V than the 2 resistors.

Re: [Repeater-Builder] Micor repeater power supply

[Neil McKie]

  If it is a TPN1105A, then the battery back-up is built in. 

  Connect your battery to the large terminal block on the back 
 through a 30 ampere fuse.  Be careful to set the output voltage 
 of the power supply so you don't boil the battery. 

  I have one of those power supplies in service here for a pair of 
 Micor Repeaters.
