picking the cleaners up now 10.00 am but it has some sort drone noise on it not that clear.so maybe your right

[radio_ryan]

re above i have heard why it may not be much activitiy on the above channels and it would explaine my question. but it is 2ed information and i feel not to be put in an open forum.

Hi


i have just checked the channel for me localy 2 of westfield channel i hahave and get builders that work at King mill, when they where building the new centre.

the on to which you get QRM is down in my data base has

westfield ch 1
CCTV
builders

from what you say and the way they are talking it the builders you are picking up from somewhere, i am not sure which builders they are. may be Andrew can help with this.

[Gemini4]

yeah definetly getting westfields co's i picked the fire up when it happened..the security there we're going mad lol.
as for the interference..it sounds so close and clear..but one of the annoying users calls BJ so loud it nearlys breaks my speakers!!!
dont think andrew lives this way does he.

I take it the builders / painters are on a different tone but the same frequency and so they are unwittingly being 'annoying'. If you don't have a box that can store same frequencies and individual tones it can't be helped. I have at least 4 users on 456.3875, some in duplex, some just on the duplex 461.8875, and the tone selection lets me pick out the ones I want and name them. This is especially helpful on the 3 x 449's, seeing as Tesco and Morrisons all have the ability to use all 3, and Asda trolley dolly's and porters use 449.400. I even have scrap yards on 449's around here.

Obviously this is difficult when it comes to 446's if you are centrally placed between two users on the same channel and tone but they are out of reach of each other. You also get 446's that transmit with no CTCSS or DCS tones at all.

The builders aren't being 'annoying', they are just pointing out a failure in your set up that can be avoided, at a cost.

I live 30 miles southwest of Glasgow, but the principles of radio are basically the same. Someone did have a pop at me once for answering outside my area' which is difficult for a global moderator.....

well thats cleared that up then Andrew..still learning everything in this..when you say it can be avoided at a cost...does that mean a big expense to eliminate these problems.
or would it be cheaper to just get another scanner.
