Midland MXT500 missing some DCS codes in its programming software.

[WROY499]

I am trying to program in DCS privacy codes on repeater channels where my club requires and I have discovered that Midland's software for the MXT500 is missing some I need.  For instance, 036N.  What's with that?  Midland strikes again.

That's because 036N is not a valid code. 032 and 043 would be standard DPL tones. What kind of repeater is it that requires that code ? Must be a CCR style repeater. The seem to use alot of off the wall stuff.

BTW - standard DPL Chart here - https://www.repeater-builder.com/tech-info/pl+dpl/pl+dpl.html

Thank you.  Not certain as to type of repeater.  New to the local GMRS club that owns the repeater.  Have sent an email to them to get more info as to why that particular DCS code was chosen.

I do see from the webpage that Yaesu and Kenwood do list the 036 DCS code.  Wrote Midland support to get an answer.  They haven't returned an answer yet.  I guess life is full of "trade-offs."  I have read that some have experienced this problem with the MXT400.

Both those lists were from HAM radios. I'm not at my work PC so can't really check my Vertex or Kenwood software. In the end its not standard which is why Midland doesn't list it. Here is a list from an old manual of the 275. Lookin back I dont see that tone in any of there manuals. The club may of used that tone to keep certain radios out of the system. I wouldn't think that would be best route but could be. 

01=023 11=071 21=134 31=223 41=306 51=411 61=503 71=631 81=734

02=025 12=072 22=143 32=226 42=331 52=412 62=506 72=632 82=743

03=026 13=073 23=152 33=243 43=315 53=413 63=516 73=654 83=754

04=031 14=074 24=155 34=244 44=331 54=423 64=532 74=662

05=032 15=114 25=156 35=245 45=343 55=431 65=546 75=664

06=043 16=115 26=162 36=251 46=346 56=432 66=565 76=703

07=047 17=116 27=165 37=261 47=351 57=445 67=606 77=712

08=051 18=125 28=172 38=263 48=364 58=464 68=612 78=723

09=054 19=131 29=174 39=265 49=365 59=465 69=624 79=731

10=065 20=132 30=205 40=272 50=371 60=466 70=627 80=732

They're missing some of the additional CTCSS tones. Per Midland, they have no plans if going beyond the standard codes and tones.

[WROY499]

Well, I have been sufficiently humbled.  Apparently, the DCS list for the Midland MXT500 is out of order.  Instead of finding 036N at number 6 on the list of DCS codes, you will find it at number 84.  Must have been an after thought on Midland's part.  Well, it is early in the morning, or I have not had sufficient coffee, or I am just plain stupid.  Please opt for the "insufficient coffee intake."

Glad you got it worked out. I found a couple of sites that listed that but said "may or may not be in radio" so I didn't suggest it. Again this is due to non standard tones. Not sure why some manufacturers use them but it does add some confusion.

Rugged Radios also lists it like Midland does.
