No - Really.? There is little "need" of energy above 3khz for male voice inteligibility.? It goes a little higher to 4k for women. If you want singing or screaming of little children, you might want

Luckily Texas went 20kHz in 146-148 in the 80s...I was the one who made the motion at a TX VHF FM Society meeting in Arlington Texas.. and it passed with only one nay...we got the entire state moved

Hi Bob,? I agree a flat repeater is nice to listen to. I have many articles about that subject on the web site.? Are you in a populated area where there is a lot of congestion on the air? -- -

The easy standard I know:?? 2x(max audio freq + max dev) = bandwidth.? Although this isn't 100% accurate, it is the approximation the FCC accepts for determining occupied bandwidth for narrow FM.?

How / when does the fan normally operate in a DR-1X? Thanks! Jeff KC8VFN

Try the input first. Not sure if you have to enable simulcast for this input to work. One more point. You can use a transformer coupled input if you want to these pins because I assume that PL is the

Have you tried old dos version Have a blessed day/n4jem

Jim, Can you give me some guidance in setting the QUANTAR to "Simulcast" so that I can use Pin 9 & 34 TX in?? I have a R2 VHF with the wireline card.? I had the software read my QUANTAR and then

I think you're the first one here to state that... and it's true! Whether you pass unde-emphasized audio through the controller, or de-emph & pre-emph, you can get "flat audio" either way. In the

Yes Burt. The input is fed from a balanced source. An input value of -10dBm (@600 ohms, which is the SOURCE inpedence) will produce slightly less than maximum deviation. This is the input used for

I would look at the power source first.

Jim, W7RY, Again, the QUANTAR stuff is new to me and I don't speak Motorolaese.? I presently have the QUANTAR set to to not be a repeater and to give me wide band audio out on pin 30 of the 50 pin

Karl's (AK2O) has some great info on his SRG website too about flat audio and some great theory that I have observed with my own eyes. Jim W7RY

THUMBS UP! Jim W7RY

STOP hijacking threads please. Jim W7RY

Have a VXR-7000 running in repeater mode with the internal controller......it keys up and retransmits fine, when the hang time drops and the repeater unkeys, it resets/reboots itself, comes up

The input is direct coupled. No transformers involved since the input passes down to 5 Hz. 73, Jim W7RY -- Thanks and 73, Jim W7RY

I know how to run the software in dealer mode, but once the software is running, I see no where to,change it…..the number in the software field is greyed out, cant type in there…..is it possible

All my repeaters , regardless of using flat or non flat audio sound like simplex...I'm a sticker when it comes to audio...too many years in broadcast engineering I guess lol...it's not hard to do

Have a blessed day/n4jem
