Programming Baofeng to talk to Vertex Standard
In one case the Vertex frequency is 445.998 with a tone frequency of 114N. As a relative novice, I take it this is a DTCS tone mode, and have coded the Baofeng as such.
In another case the frequency is 445.997 with a tone frequency of 82.5, which I take it is a TQSL tone mode.
Third case frequency is 456.378 with tone frequency of 114N, which again I presume is a DTCS tone mode.
Any suggestions of what I am doing wrong ?
I have coded the UV5r to talk successfully both ways with a VHF radio on another shoot, so this really perplexes me !
Something to look at would be making sure that the tone for both TX and RX;
IE: You said one channel had a frequency of 445.998 with a tone of 114N. You are correct in assuming this is a DCS tone, but make sure that 114N is the tone for both TX and RX from the Vertex. If they are different then that would be why the Baofeng is receiving, but not the Vertex.
A way to fix this is a process I use a lot to find those pesky tones. It may take a while but eventually you will find the right tone. On the Baofeng, manually key in the frequency for the channel you are trying to link with the vertex, then go to the menu and manually test transmission on every TX DCS/CTCSS tone (depending on which protocol is used on the channel). Eventually, once you hit the right tone, the Vertex will receive the full voice.
I've posted the CHIRP data on the next post
On your channel, you'll want "Cross Mode" to be set on DTCS–>DTCS. With the setting, you will then be able to punch in both your DTCS code and your DTCS Rx Code, and the polarity (this is usually NN). The frequency you type in on the very left is your TX and RX frequency for simplex, so I don't think you'll have to do anything with offset.
