Link-Comm controllers used to have this problem in that the breakpoint was effectively 600 Hz, not 300. I actually like to go much lower to make the repeated audio as flat as possible without resorting to the direct FM approach. Try listening to your "tinny" users directly on the input, & output (through the repeater). If they sound tinny both ways, I'd leave it alone. Bob Yahoo!

Re: [Repeater-Builder] Tin Sound Audio
Thanks Bob, will try this and see if there is any changes. The audio on the repeater actually seems fine to me, with the exception of a few folks, and they have used other radio's, and about the same quality, but in person there voice sounds nothing like they do on the repeater. Will see how it works.

Re: [Repeater-Builder] Tin Sound Audio
I have a MASTR2 on 6 meters and rolled off the high frequencies. I find that noisy signals are more readable this way, as background noise seems to be mostly high frequency. It makes the repeater a little more bass, but improves useable coverage. Maybe it's just my ears. 73, Joe, K1ike --- Q <[EMAIL PROTECTED]> wrote: > Why guess?

Re: [Repeater-Builder] Tin Sound Audio
Mat: You don't say how you are using the M-Pro Rx. The Vol/Sq Hi point is the best point to get audio from the Rx on older M-Pro Rx, if you have a plug in card shelf with a remote audio card in it, the 600 ohm line output is a better source of audio as it is already de-emphasized. If you are using a repeater controller, there should be some means to select de-emphasis on the audio input to it. If not or you are using some other method to interconnect your Rx/Tx, you'll probably have to build a de-emphasis network to go in the audio path. If you have a copy of the 600 ohm line driver card that mounts in the EP38 power supply in early M-Pro, there is a simple de-emphasis network on this circuit board that you could copy.

Any idea where a good point would be to get the audio from on the Mastr receiver would be. I do have the schematic so if you could just give me a reference point that would be very helpful.

Re: [Repeater-Builder] Tin Sound Audio
Mat: The de-emphasis network on M-Pro receivers is after the Volume Control. Since you are getting your audio feed from Volume Control High, you will need to provide a de-emphasis some where in your interconnect/controller to get rid of the tinny sound.

Re: [Repeater-Builder] Tin Sound Audio
Never thought of listening to them on the input. Most of the guys I know do sound the same, but there is just a select handful that just has that tinty sound. Will do the input check and compare that way. My audio coming into the repeater sounds just like me, so I know it's not really just the repeater, just thinking ahead here. Till someone complains, I will just leave it be. Thanks again for the input.

Re: [Repeater-Builder] Tin Sound Audio
Why guess? With proper test equipment you can plot the response and see what its really doing. A "good" repeater will faithfully reproduce what it actually hears without changing the response. There is a good discussion in archive and on the repeater-builder site about pre-emphasis,its a must read for repeater owners! After you insure the repeater is performing well,then you can tell those that sound tinny that its their equipment which is at fault. There should be little difference when you listen to a repeated signal,then switch to listen to them direct on the input and compare the audio.

Re: [Repeater-Builder] Tin Sound Audio
most of them are using yeasu radios with stock mics that came with the radios. Just want to make the audio a little more to the base side rather than the tinny sound I get, but thought I would just play with it to see if it could be changed a little. But I do agree with what you are telling me.

Re: [Repeater-Builder] Tin Sound Audio
If its say a few stations, I would ask what kind of a radio they are running, be surprised at the answers I found a few that I would like to share .. 1) Yeah I am running my D-104 Lollipop mike from my CB on my XYZ Radio that has HF , 2M. and 440 sounds good doesn't it ? 2) Well I bought this at ABC Radio Shop and I got a dandy deal for $1.95 they said they work good on ANY radio. 3) well I had to turn up the Mike Gain ( in Actuallity the Golden Screwdriver clown turned his Devaition Control pot as far as it goes ) so it sounds really loud how do you copy me now ? If the idiocy of these types on 2M. have carried their so called professionalism, and after monitoring or talking to these YAHOOS makes you wonder.
