Guest WRVY696 Posted January 28, 2023 Report Share Posted January 28, 2023 Decode/ encode on the digital private line ( dpl265); on the drop down menu, is there a difference between d265n and d265i ? My radio is a radioddity db20-g. Forgive my lack of knowledge, it's my first day. Chris Quote Link to comment Share on other sites More sharing options...

Usually if the letter is omitted, "normal" is assumed. At worst, if one doesn't work, switch to the other.

WRQI583 Posted January 30, 2023 Report Share Posted January 30, 2023 In my over 30 years of radio, what I have found is that the NORMAL version of the tone is what is always used, so its best to go with that first. There are many articles online that explain the difference between normal and inverted if you google them. Quote Link to comment Share on other sites More sharing options...
Radioguy7268 Posted January 30, 2023 Report Share Posted January 30, 2023 ... and you will also find out that every normal DPL code has (at least 1) matching invert, which is really just another number on the DPL chart. So folks who (over)think it and decide that they're getting some type of super special "secure access" on their repeater by choosing some odd-ball Inverted code end up baffled when someone sniffs out their code over the air within 30 seconds. Inverted code/matching std code 023 047 025 244 026 464 031 627 032 051 036 172 When you're dealing with digital ones and zero's in a streaming bit code, the patterns end up repeating themselves, even if your bitstream originally started with a 0 instead of a 1. Someone with more patience and knowledge explained it better than me, but if you want to go for a deep dive - here it is: DPL demystified WRUU653, PACNWComms and wayoverthere 2 1 Quote Link to comment Share on other sites More sharing options...
