I was looking at a repeater directory at 70cm repeaters and many of them, under the PL tone say DGTL, do I need certain equip to use a digital repeater or can any 70cm HT use them? Thanks.

Hi Matt - in this case it means that the PL code to enable
you to key up the analog repeater is not a subaudible tone
but instead a short digital sequence.  It is commonly
called DCS - an abbreviation for Digital Coded Squelch.

It's available on some amateur FM rigs. You need to have
an FM rig that has the DCS feature installed. For example
the current Kenwood HT  TH-K2AT has it available.  Just
check the manual for your rig. It's not new, but has been
available for some time.

Oh I see ok. Thanks! I just have a baofeng and I do see R-DCS and T-DCS so I guess I am good! Do people in your area even use 70cm repeaters? I have been listening for 2 months or so and have never heard anyone on one and there are a lot of them in my area.

Also, when I go into R-DCS, I see D754I, D743I, etc etc. The repeater directory does not specify which one, just "DGTL". How might I go about finding which one to pick? Thanks again.

I don't think DGTL means DPL. it means DGTL as in DSTAR,P25,DMR and those would need a special rig.

most lists will show DPL as D072 or similar.

Not so sure. I have seen PL repeaters that do not list PL frequency in directory. Same can be true with DCS.

I always check the state repeater council to double check. most will post a repeater list of coordinated repeaters.

repeaterbook.com does a decent job. and repeaterbook.com DGTL = digital mode repeater.

And you are right not all lists are 100% correct. some machines get converted to DMR or another digital mode, some that were CSQ end up having pl turned on. but between the state coordination list and repeaterbook.com you can get at least 99% of the info.

Most of the lists I have seen show DPL, DCS or something similar for Digital Code squelch, and typically also have the number listed (for example 072) in the tone entry. Most analog only HTs (like the Baofengs) and mobile units are able to use either the DCS or the CTCSS tone.

DFM or DGTL usually means Digital FM mode such as C4FM (Yaesu Fusion), Dstar, DMR, etc.
