I have a local repeater that I have permission to use. The CTCSS code is 67.0 and according to the Midland conversion chart they do not have 67.0. They only have 67.09 code 1.
Is there something i am missing?
Hi karpy, welcome to the forum!
67.0 is a pretty standard assignment for tone 1 across the board, and I am unaware of any CTCSS tone that uses a .09 or anything in a hundredth of a hz. I checked the manuals for several other Midland radios and they all list 67.0 as tone 1, with an exception of the MXT115. The MXT275 is similar to the MXT115, however instead of a display and control panel on the radio, the controls are integrated into the hand microphone. Itâs possible the CTCSS tone chart was duplicated from the MXT115 manual to the MXT275 manual. My guess is the .09 is merely a typo, and itâs really supposed to be 67.0.
Of course, the real test is to try it, and if the tone 1 setting gets you connected to the repeater, then itâs probably just an error in the manual.
Sir
Thanks for the reply! The Manual that came with the radio MXT 275⌠has only 67.09 code of 1. I also thought it could be a typoâŚnew to GMRS and donât want to mess up a new radioâŚSorry I am a newbie!
I will try when I get home.
Rick already answered your question but I just wanted to add that you are not going mess up your radio by choosing the incorrect tone (code). The worst that would happen is you wonât be able to use the repeater. You can simply change the tone (code) to something else if it doesnât work. The nice thing about Midland GMRS radios is they are made almost sailor proof (I was a sailor) even though they chose to make you cross reference tones/codes. I personally know someone (me) who made a mess of programming an amateur band handheld to the point that the easiest thing to do was to perform a factory reset and start over. Have fun.

As an interesting side note, ETSI actually defines an maximum allowable frequency error for CTCSS which is +/- 0.75%. At 67.0 Hz, thatâs +/- 0.5 Hz so thereâs a full Hz of leeway so even if the frequency was actually 67.09 HzâŚthat is still within allowable margin.
