NC 2 meter FM simplex
 
Is there or has there been a widely used frequency split for 2 meter FM simplex in NC? I make calls on 146.52 from time to time and have gotten some contacts. I can obviously just tune to any frequency that the contact wants to use but if I was gonna program them should I use 15/20/30khz splits?

in the range of 10 & 15 years ago, Raleigh Amateur Radio Society (or some of the officers in at that time) were promoting use of FM simplex, and picked 147.420 simplex.

I think it suffers from lack of use now, just like the way analog FM repeaters seems to.

I think you mean channel spacing, which, according to the 2010-2011 ARRL Repeater Directory, is 15kHz in NC. 146.520, 146.535, 146.550, 146.565, etc.
A frequency split refers to the the difference between a repeater's input and output.

Thanks! That's a solid answer. I need to get a repeater directory. Yeah, I saw where somebody called it splits and as wrong as it seemed I went with it. Channel spacing makes more sense.

JJ, try this. Just type in State and Distance

repeaterbook.com is a great website, and the smartphone app is really super.

JJ, Here's another

The organization that coordinates repeater frequencies in the southeast (SERA) has put out (on their website) a band plan which designates specific frequencies as simplex only and you can also see where all the repeater pairs are. Although there is no requirement to use these, I have programmed them all into my radios for easy -QSYing without worry of being on some coordinated repeater input. You might want to take a look at it.

And because I am such a nice guy, here is a link to the page with all the band plans.

Dang it Rapid! Now I have a year membership to SERA.

146.520, 146.535, 146.550, 146.565 are the best to try. when i was going to UNC-Wilmington back in the mid 90's 147.555 was very popular in the Wilmington area.

Thanks. Going up from 520 makes sense and I've heard a local mention 555 before.

147.555 is popular with the ARES groups, Guilford County ARES uses it.

15 Khz step is the standard for analog amateur FM. period.

You are wrong. In many parts of the country the 2 meter repeater band plans are on 20 kHz spaced channels.

In Iowa, the "145" repeater outputs are on 20 kHz spacing. 145.130, 145.150, 146.170, ect. . . . "146 & 147" repeater outputs are on 15 kHz spacing, starting at 146.610.

In this area (Piedmont) 146.535 is one of the most popular simplex frequencies in use. Mostly to get away from National Simplex. There are a few echolink and IRLP nodes in/around Charlotte and maybe towards Hickory on 146.52 that make random announcements (I think the one near Hickory broadcasts a message every 10 minutes if memory serves) and kind of make the use of it rather difficult.

In Arizona and much of the West (as of the 2010-2011 ARRL Repeater Directory), it's still 20 kHz for analog FM. (Digital repeaters are 10 kHz spacing with a -1 MHz split on 144 MHz in Arizona.)
Check with the local coordinating body for your state/region, or the state/region you're visiting, for proper channel spacing, repeater split, and analog/digital allocations. You should be able to find contact info in the latest ARRL Repeater Directory.

please refer to three things: 1) the page you are on is the "NORTH CAROLINA Radio Discussion Forum".......2) the title of the thread is "NC 2 meter FM simplex"....and 3) the body of the question specifically asks for local NORTH CAROLINA information only........is there something about this you don't understand ? all my answers hence are specifically implied as being North Carolina information related only...not arizona...not many parts of the country...NORTH CAROLINA ONLY....sheesh....

so.......once again.....the answer directed to jeepinjeepin is :

15 kHz STEP is the standard for 2 Meter analog FM . period.

PS: jeepinjeepin : congrats on joining SERA....well done ! the Repeater Journal is going thru some rough patches at the moment, but hang in there....a wealth of LOCAL NC info on hamfests/repeaters etc......well worth it !

Second the congrats on becoming an associate SERA member. The center of each issue of the RJ includes repeater listings in all areas it coordinates. There is also a listing of recomended simplex freqs. While you're waiting for your first issue to come in the mail, take a look at my ham website on qsl.net. Look for the repeater link. The listings are for my area, but what you would be interested in noting at the beginning of each band listing is the channel spacing and offset info. This is the setup for all areas covered by SERA. Note especially on the 2m section the group of outputs centered on 147.000 (offsets can be either way)!

Yup. 146.865 near me is an odd + offset.
