Repeater heard on uv-5r but not on ubc125xlt !

Postby Bobcode » Mon Feb 05, 2018 11:36 am

Good day everyone,
I am very new to the hobby so I may be being a little dense here, my uv-5r picks up a repeater on 433.175 very clearly just using the standard antenna whilst sitting in my living room. My ubc125xlt scanner does not, nothing heard at all.
My question is, why ?
I am not licenced, yet, that may well come in the fullness of time as I am now retired, so the uv-5r is purely for rx and nothing else.
So what am I doing wrong with the scanner chaps ?

Thanks."?....

Is the attenuater (ATT) on your 125 set to on...? If it is it will reduce the signal strength...

That should be the Ipswich repeater on 433.175 & are you saying that in the same location one radio picks up the repeater & the other does not? Or that your UV-5R picks up the repeater, but else where?
Is your attenuator off? It should be.
Also how high is the squelch set on the scanner? The squelch should be set to it's lowest point possible. Just so it stops as many unwanted signals as possible, but you want to hear weak signals too, so not too high.
But small distances can make a very big difference. My own handheld picks up my local repeater pretty much all over our house, but my wifes does not & to use the repeater, she needs to stand in one position. My handy is not good in the Kitchen, but as long as I keep it in one small area it's OK.
Comparing two radios in different rooms of the same house is not going to prove anything, nor is different places in the same room.
My guess would be & assuming that the CTCSS & DCS are off on the 125 & that the squelch is set as it should be. Is that what is happening is simply down to one radio being designed for two small bands with a antenna that is the same. While the scanner is designed to cover a massive amount of spectrum with an equally compromise antenna. But as I said small distances make a big difference. So try your scanner else where, especially in front of a window facing in the direction of Ipswich.

Attenuator on/off, I did not know this was an option, Where is this setting?

Looking at the manual it does not look like it has one :shocker: :shocker: Hence why handhelds are not good on larger base antennas. I was just working through potentials & most radios have a attenuator for good reason.

Thank you gentlemen for taking the time to reply.
I have checked the manual and can find no mention of an attenuator on this scanner, is this right?
Yes, sitting in exactly the same spot and holding both scanner and radio in the identical position, the uv-5r chirps up but not the scanner. Subsequently I tried in many and varied places with the same result.......

Meant to say, squelch down to 2.."?

Getting the squelch right, is down to trial & error as the setting is going to vary from location to location. If it's too low, the radio will not scan & get caught up on every silly little noise. But too high & you will miss a lot.
The problem is the background noise level will vary not just from location to location, but also sometimes by what time of day it is. During the evenings here I get a lot more background noise due to more people being at home & thus more electrical noise, as an example.

Thank you mOlsx, I will persevere with the scanner next time the repeater is heard on my uv-5r, I am sure this is going to be an interesting hobby!
Knowledgeable people such as youself will make the learning curve less steep, thanks for your input....

Sorry my mistake... most unidens I've had did have an attenuator and I thought that could have been the problem...

As molsx says tho... the uv-5r is a dedicated tx/rx for that band with a dedicated antenna... the scanner is a jack of all trades wideband and not as finely tuned so that may be why... have you tried opening the squelch on the 125xlt to see if you can it at all...?
