New user - UV-5R question

Postby Rick101 » Wed Jun 01, 2016 8:52 pm

Hello,

I'm new to radios and hoping someone more experience can give me some help with a UV-5R I purchased.
I have done some reading but am failing to get the connection I need for some reason.

They radio is used to communicate with friends when driving in convoy on legal 446 frequency.

My friends have simpler radios and the display shows 1 19dcs
I understand this to mean Channel 1 (446.00625) with the digital squelch set to 19 or (D116N) as per the table in my handbook.

I've set my U5-5R to 446.00625 (with dcs off) and can hear them but they cannot hear me due to their dcs setting.
I've tried setting my DCS transmit and receive setting to D116N but that blanks it out completely, almost as though 116 is not the correct code for 19.

Just as a control have tried on channel 2 with no encryption and that worked fine both transmit and receive.

Can anyone confirm if D116N is correct for a DCS setting of 19 or is there something else I need to set on the radio for it to work?


Thanks

Rick

You may be on a PMR 446 licence free frequency but your radio does not conform to the requirements to be on PMR 446.

http://stakeholders.ofcom.org.uk/binaries/spectrum/spectrum-policy-area/spectrum-management/licence-exempt-radio-use/licence-exempt-devices/Analogue_and_Digital_PMR4461.pdf

Refer to page 3 of 6 at the bottom - PMR446 equipment is limited to 0.5W ERP - The Baofeng is 1w (low) and 4w (high).

I didn't think many people used DCS but ordinary CTCSS tones? I guess what you will have to do is programme in the same frequency to a load of memories but each with a different TX tone until you find the right one unless you have a monitor that tells you what tone they are really using.

A scanner with close call would help identify frequency & DCS or CTCSS codes./
Another way is are all the other radios the same make & pre programmed? If so google could help.

Thanks all. Seems not a simple way to do it. Will see if i can find out their pre programing.

Just a thought by why is the DCS code set to 116N? Is the N not setting it to inverse?? It is on one of my radios.

Ahh may be something there. Scrolled right through from D23N and eventually got to D754N then it started again with D23I.

Have set to D116I, will try it again next time I see them. Hopefully that will work. Many thanks.

I have a radio, I forget what make, but the letter I (India) after the DCS code is the code wanted for normal use & N means inverted.

Tries 116i but still not working.

Simply can't understand why I'm having so much trouble trying to make a connection.
I did find some information on websites this morning which suggested the UV-5R can scan for DCS tones.
I will try setting one of my radios with DCS and scan with the other . If it picks up I'll then try and scan my friends and see what information it gives. Maybe the 116 is wrong.

From Wikipedia:
(https://en.wikipedia.org/wiki/Squelch#DCS)

"Radios with DCS options are generally compatible provided the radio's encoder-decoder will use the same code as radios in the existing system."

Just use CTCSS.
I reserve the right to ignore people who have made no attempt to the read the manual, and expect others to do it for them.
