Creaking door sound

[Fred -]

Did anyone else notice that opening some 2m repeaters produces kind of a creaking door noise?

When opening the same repeaters with other transceivers, there is no such sound.

I hope, it is just a minor issue and not a sign of something broken...

[David Colson]

I have one repeater that seems to do this but not all the time. I didn't notice it on my other radio.

Mine sounds more like motor boating, if you know what I mean.

[Fred -]

Yes, true, the first one sounded like a creaking door, the second one now like a motor boat - that describes it quite well.

Hi Fred

Not knowing your setup, BT microphone of used and version of firmware, mobile or fixed. 

My crystal ball is a bit cloudy this morning 😫😫😫. 

An audio issue I did hear about was pager 📟 noise from stations tx that were not filtered and their tx was broadband !!!!!

Doesn't matter which microphone. Happens with all of them and also the smartphone speaker. Using latest firmware 0.5.1 and being at home.

[David Colson]

Just some more info:

Rx freq: 145.130

Tx freq: 144.530

pl tone: 107.2 (both tx and rx)

Only notice it on channel one.

BW: 25KHZ

latest software

Using the wired mic.

Also, as I said before, it is not all the time.

[Fred -]

Yeah, I should also add:

first time it happened: RX 145.600, subtone: 71.9, offset: 0.6

second time: RX 145.7375, no subtone, offset: 0.6

So the phenomenon seems to walk around.

[Fred -]

Do not see a way to edit my post...

Bandwidth 25 kHz, too.

[Fred -]

In the meantime, did anyone else observe this "issue"? And what could be the reason?

[Mark Karagas]

I just got my new radio setup and someone on our local net said that my signal had a screeching sound for less than a second at the end of my transmission. I tried it on my dummy load today and I can hear it. I tried turning on and off "tail elimination" and it didn't make any difference. I also unclicked "emphasis/de-emphasis" on each channel that I programmed, no noticeable change either. Is this the same issue that is being discussed here? Just curious. 73 K5MGK

[Fred -]

This is not the same phenomenon that I described in this topic.

[Marnoch Standen]

The sound at the end of an over is the ID feature that has not been turned off.  All 3 ID buttons have to be off.  

This is a feature that other radios working this app can see the distance and location of each other.  

If you read the documents for best setup it will save the new owner problems.

The problem of mkar...@gmail.com might be solved by what Marnoch explained.

But again and not to confuse others or no longer get helpful comments:

This is not the problem I was hoping to get answers here! The "creaking door" sound is something that happens from the very start when keying up some repeaters (2m only, as far as I can see) and it persists during the QSO when the *OTHER* OM is speaking. Moreover, it does not always occur. I do not see a consistent pattern, but with most repeaters it never happens.

[Fred -]

Marnoch, you asked for a sound file of the "creaking door phenomenon". Listen to the attached file.

[Carlos Navarro]

Where would I find such document?

Hi Fred

 

That is a strange one and can’t think that the radio could produce that sound but I willing to learn anything.

I have heard of interference from pagers locally that aren’t filtered correctly and the wide band open front radios have now a days.

 

Wonder if others have any sensible suggestions as it would be interesting to compare it with another radio.

 

 

Most people have the ID and position data tones at end of TX problem as there is no detailed manual on the radio, only what does this do learning J
